Side by Side Comparison of: Long Run Technologies USA vs UNU

I never realized how much I depended on this case. It's a life saver because I constantly drain my iPhone4 battery. When the product stopped working I ordered another one because it worked so well and I was very satisfied with the way it works and protects my iphone. On the second order I mentioned to the company that I ordered another one because the first one stopped working. They responded immediately. The service was fantastic and beyond what I expected. I may also order more in the future because I want one for each day of the week so I never run out of battery power. If I buy more, this would be the one I would buy.

I liked the case so much that I bought 2 and would like to share some insights regarding there case/batteries for IPHONE 4S of which I have several I have been through several OTHER big name case/battery products, including M****e, I find these on par or better them these, here's why.

The case is thoughtfully designed to not be slippery in the hand. The design and production was well executed I say this because the case has a remarkably good tight fit to my IPHONES, there is no wobble and the upper and lower portion of the case mate perfectly. I know these are for IPHONE 4 so take these next 2 observation with that in mind ... I wish the designers would fix 2 things in future issues of the case, (highly unlikely additional IPHONE4 cases or battery will be done again). I find the lights on the bottom to be annoying when the phone is charging because they stay on, can't figure that out, I would have expected they might come on for 45-60 seconds and then go out, to my experience they don't. My solution to this although primitive is very effective to me a piece of black electrical tape about 1 inch long sliced down the middle and placed over the lights, I get my charge information mostly visually from the front of the phone, this works for ME; your mileage may vary.

Secondly I wish in future editions (if there will EVER be any) that the Mirco USB charge port would be located on the bottom or top. I question why the designer put it right on the corner, I suspect that this was done to be like other big name manufactures. Follow the enclosed instruction and charge up the case for the time interval indicated.

When needed the case has charged my phone pretty darn fast. The supplied micro usb cable seats well into its port, to my feel it is a good solid connection. The top audio out port is easily accessible through the top half of the cover and I use a stylus with a plastic plug all the time. Also the left side cutout to operate the vibrate mode on / off switch is easily accessible for those meetings when you for get to put it into vibrate mode before hand. First photo is with tape in place, second is with tape removed and charge indicator MANUALLY turned, third photo is the placement of the micro usb charge port. I feel that I got good value for my money as I have paid over $80.00 for similar cases. These cases will protect and let me keep my IPHONE4s a while longer and remove running out of battery too quickly when I am away from electric power for extended time periods. I would buy theses cases from the same vendor in the future if I needed to. -mh

This is an awesome product! It protects my iPhone when I drop it, and it can recharge it while I'm on the go. As my phone gets older, it drains faster. As I add apps, it drains the chattery faster. This case has saved my bacon more than once. I use it daily. I'd recommend it for anyone who needs backup battery power.

Best purchase since having my iPhone 4. I choose free shipping, since I also bought another item, and they came when promised. After fully charging the included battery, I put my phone in the case nice and snug, and everything lined up perfectly. At night I charge my phone and the battery in the case at the same time, plugging the included cord into the cube that came with my original cord. The case makes it easier to hold my phone, as it adds a a little heft and is comfortable to hold. It looks like a part of the phone and gives it an updated, larger look.

It does everything it's supposed to.

So far so good, arrived on schedule and even and a 1/2 charge. Iphone 4S fits like a glove . I like that they put the usb plug on the side vs bottom so I don't knock it around on the nightstand. Also the on/off switch is a really nice touch compared to others which you have to hold down the charge display button to turn it on. the charge Display button is on the bottom with 4 led indicators. Its a little larger then my original one but not much. Actually feels more comfortable in your hand and top portion seems to be more solid then previous one I had.

This UNU battery case works great, I did not want to enter a comment until I had some reasonable time to experience it's functionality, and I am very pleased with the fit and fell, it may be a little thicker than other protective cases with-out a battery but I like the fact that you can hold the cell phone with a better grip.The silver-white combination gives it a classy look, I look foreword to my cell phone having great protection, a full load of added charge time as needed and an extended cell phone battery life with this product.

I already have the Power DX version and love it with one exception . . . the upper slide-on/off piece which allows you to remove the battery from the iPhone, is very fragile and I have gone thru 3 of them (they are available online). After the most recent breakage of the piece, I decided to try this Power DX PLUS battery and I find it to be a more rugged version. Although I have only had it a short time, I fully expect it will solve my breakage problem.BTW: The "slide on\off piece" on the "PLUS" version is not compatible with the non-PLUS version in case you are considering buying one as a replacement for installation on your non-PLUS battery.

I purchased 3 uNu cases. A 1700ma for myself and two 2400ma cases for family gifts. They all more than met our expectations. I've had Mophie and 2 other brands that failed in less than 3 months. They failed because of the mini connector on the case stopped accepting a charge or detached from the case internally. The uNu cases are good quality and have performed extremely well from day one. I get 2 days from my 1700ma and my son and daughter in law both are averaging 3 days from their 2400ma cases. We all added the dry transfer screen offered by AT&T and have come up with a no-fuss operating mobile phone. This case is very reliable and would recommend it to any 4s iPhone user.

Three weeks after ordering this, I decided to test it to its maximum capacity as I wanted to drain the 4s battery and fully charge it as I do once per month. I had fully charged the uNu a week earlier and I had not used to fully recharge the 4s. I left home on the way to work with about 32% battery capacity on the telephone with a 90-minute commute ahead of me. I listened to music and downloaded a dictionary on the way there using 3G on the subway. I also conducted a couple web searches. On my return trip home (I leave my phone off at work), I began with ~18% battery power (these percentages are all according to the meter on the iPhone). I allowed the telephone to drain down to ~1% battery power before turning on the uNu to begin charging my telephone (it took about 30 minutes of reading an e-book, downloading a dictionary, and checking six email and three text messages to go from ~18% power to ~1% power using 3G with WiFi turned on). The telephone continued to charge throughout my trip while undergoing what I would consider to be moderate-to-heavy usage while on a typical subway commute (listening to music, and conducting a 3G download of two e-books on the way home at one stop with decent cellular coverage, all while reading another e-book - no talk, however). When I returned home, I began browsing the news using WiFi while still using the uNu to continue charging the battery. A little over two hours after I starting charging the telephone using the uNu, it stopped charging the 4s battery. My battery indicator read the telephone had reached a 78% charge.I cannot say whether all will get these results, but I think they are reasonable for commuters who use their telephones for entertainment while commuting. Also, I cannot say whether or not this is the best phone case for all as I have never dropped the phone using it and I have never broken a phone because I dropped it on the ground (water will be likely to get in if you drop it in a tub of it). For those primarily interested in battery life with a least some regard to telephone protection, this product delivers.

I've had such positive experiences with the DX-1700 by uNu that when I saw the DX Plus I knew I had to get my hands on it and see for myself if the DX Plus is a worthy successor. Dissatisfied by the majority of existing reviews on the DX Plus, I decided to create something that would give the average consumer, like me, a glimpse of the product before committing to a purchase.As a consultant, I run a hectic schedule that demands mobility and flexibility. Being on a conference call for an hour while driving or working at a client site can be taxing on my iPhone's battery, which initially led me to look for a viable solution to additional battery power. Enter the DX Plus.The Good:1. Competitively priced with a great balance of quality and reliability.2. The DX Plus echoes the aesthetics of the iPhone's design, especially the glossy white and silver trim. And speaking of design, the battery case feels like a cohesive unit. No clumsy wires or additional cables to carry around.3. It works, and then some. I can go an entire day without plugging in my phone to a wall charger, and that includes web surfing, sending/reading emails, and running various apps.The Bad:1. The DX Plus will add some considerable bulk to your slim iPhone.2. The DX Plus adds extra weight.Bottom-line:At 2,400mah, the DX Plus was aimed at a specific target market - power users. That's 10 hours of extra talk time! I've checked the power capacities of other brands and the DX Plus has more juice than most. Indeed, this thing will make your iPhone feel like a mini-tank, but in my humble opinion that's a small tradeoff for the convenience and peace of mind in knowing that you won't be stuck without power when you need it most.

I have had the case for 7 months. I like it very much .The good things are1) The case seems very well made. I purchased a DX-04-2400 White base with silver bumper case, the white piano finish looks every elegant2) The textured feel of the case is good. Less likely to drop it, and not prone to fingerprints and smudges. And it is slightly less likely to fall out of my shirt pocket when I bend over.3) It protects the phone from drops and most types of damage very well. The phone almost bounces ,and I have never had any physical damage to my phone since I use this case.

iPhone 4 and 4S is less and less in demand. But for those of us who still have them we still pamper and coddle them.

My first backup back died and this was its replacement. Any color you want as long as it is black. Amazon delivered as promised, good. The shell/case of this backup is very good.

However, instructions were on one piece of paper with no illustrations nor diagrams. There is a good length USB to micro USB and yet the length of the micro USB port to the backup is, IMO, deeper than many mini USB connectors. One needs their cable or a mini USB connector that might be longer than what you are used to putting into your devices.

The length to charge is decent, but it seems to discharge at a faster rate, or just doesn't have the capacity I was hoping for.

This battery case is still charging after a couple of months. So far so good. It also charges phone first then the case. The flip switch has to be pushed firmly to charge though. Still it has been an excellent product.

very handy device. you get the extra power that you need without having to charge your phone. Definitely nice to have

Durable case and long lasting external battery.
I would choose this product again.

Just got the case and it seems great so far. A little bulkier than I expected but that didn't affect my rating. It would have still received 5 starts if the case didn't constantly have my power button pressed in.

Have used it successfully with my our iPod generation 4. its smaller than iPhone 4/4s so buttons aren't as accessable as much, but the battery was shot on the iPod and now we can use bluetooth without being plugged in continuously. I initially bought an external battery pack for the iPod but having have two of them connected all the time was a hassle. I Like this better, you have to stick your finger under the frame to get at the shut down and turn on buttoned and there is no way connect headphones. But for bluetooth play with the iPod in our car or boom, it works great.

Great Battery Case. NOTE: uses Micro USB plug for charging - does not have iphone style plug on the outside of the case. So when it is connected to the phone, the only way to charge is to use micro usb. I think most people like me have a bunch of micro usb chargers as well as iphone charges so be prepared to break out the micro usbs for when you want to charge this up.Also, the case doesn't need to be off or on after charging when the case is on the iphone. If you leave the battery case "on", it will just provide power for the iphone 4 or 4s during the day until the battery case runs out of juice. Then the iphone battery will kick in, and this should be *significantly* longer than just trying to run on your iphone battery. Or, if you turn the battery case off after charging (holding down the battery case button for 2-4 sec) it will remain off and the iphone can run on its battery, then when you need it you can use the battery case button to turn it on and charge the iphone.Either way for me it's been about one charge per day, or on a couple days it has been about a day and a half before both need a charge.The iphone will be getting two charges (one with the battery and one with the wall) if you turn the battery case off during the day when unplugged. Or it will just get one charge per day on its battery if you leave the case on... (it will only actually use the iphone battery towards the end of the day, then both will recharge full, then you start out running off the battery case. I think this is better for battery cycles on your iphone - cause you can always get another battery case.The only thing I would say is that the plastic top piece which clicks over the phone to enclose it into the larger battery case is somewhat hokey - the plastic detent clips wear easily and I ended up playing with it, causing it to slide right off in no time. So I had to add tape to thicken the plastic before I slide it on.

The UNu Power battery case for the iPhone is an affordable alternative to the better known Mophie. The case feels solid and fits well. It's also pretty thick, about 3/4 inch, so it's noticeable in your pants or sport coat pocket, not much so in a backpack or outer jacket. It's a hard case that feels like it offers some protection but this is not an Otterbox Commuter.With my phone's aging battery (a year old) and this new case fully charged, you can go a full day, all night, and into the next day with the phone mostly on standby, some talk, a little web browsing. If you use it for GPS navigation, that sucks down power but still you won't run the phone dry even if you stay out late.The worst part: The manual is poorly written by a non-native English speaker. It's unclear in the extreme about whether you drain the phone battery first or the case battery first in order to maintain the built in battery for many more months. It's also unclear how the button on back works, that is when you press it, how do you know if you've turned the battery flow to the phone on or off. (When the case is unplugged from power, if you just turned the power flow on, the charge light on the phone glows green.)There are 4 blue LEDs on back to indicate state of charge. Some people may find them too bright to leave on the nightstand without tossel a washcloth or T-shirt over it. Overall, mostly because of the price the competition, this feels like a good deal. If you're iPhone battery if fading and you need to make it last 6 more months, you're willing to pay $40 for a battery case; it stings to pay $100.

I have owned this for over a week now, for the most part it is great.The good: The charging port acts as a pass through port to the phone, so rather than taking the case off and plugging in your 30pin cable, all you need is a micro usb cable to charge and sync with iTunes. It is definitely meant for big hands (some may see this as a downer however.) The battery makes my phone last from the time I take it off the charger in the morning between 9-10am and lasts until I goto bed at 1-2am.It will take my phone from 10-15% right back to 100% in about an hour Which is great, no more car chargers, no more charging at school or the office. It matches the white iPhone nicely.The Bad: Case gets hot, although it is a once in a while thing, but it happens. Poor internal design. I had to see how the internals worked so I cracked it open (Yes, total geek) The circuit board has a small black plug, like the motherboard case connections in a computer, tiny. One drop and this portion was damaged, however a little solder and realignment fixed it. There is a piece of plastic between the volume + and - buttons, for big hands/fingers this is bad, if it were between the volume + and the vibrate switch it would have been fine, I ended up cutting it out and filing it down smooth to get rid of it, to me it was extremely annoying.Everything considered I would recommend this to everyone, although some may need to slightly modify it as I did. It allows the iPhone to last all day with heavy usage and makes the phone fit better for those of us with large hands.

I had a Mophie prior to this one. The Mophie's mini USB jack became too loose to charge it, so I purchased the uNu. I am frequently on the phone during the day away from chargers. I cycle and at the end of the work day I need enough additional power for at least two hours to run my GPS mapping app, MapMyRide, while playing music, through the speakers, from Rhapsody. The uNu handles it beautifully. Have only once run short and that was more me than it.It is noticeably heavier than the Morphie, but it also has more power, 2400 MAH versus Morphie's 1500 MAH. It has survived numerous drops. The biggest problem is the case interferes with the camera, especially the flash to the point you have to remove the case to take a flash photo. The other slightly annoying thing is that it is more difficult than the Morphie to know if the external battery is on stand-by or connected to the phone.

I ordered the case basically because I travel all the time, or I'm working all over and I want to be able to watch my tv using slingbox on my iPhone 4S. Before I got this case I could watch maybe a 60 minute stream using 4g or a 100 minutes connected to wifi before my battery would be dead. My times are estimates because honestly I don't remember, nor do I care because it was very frustrating always looking for somewhere to plug in my phone.When I got the case and put it on it made my iPhone bulky, kinda ugly, but I guess I should have expected that. The case fits almost perfectly, not perfect because the case is 2 pieces that connect top to bottom. I don't fault them for this because after all I want function not style. The first day I took my iPhone in the new case to work I also took a charge cable(which by the way is not an iPhone cable, it's a micro usb). The micro usb cable plugs into the bottom of the case, thus why a traditional iphone cable won't work. I have been using my case for 3-4 weeks now and the charge cable has still never been used at work. I am one of those people who always charges my phone at night, however during the day my percent has never gone below 86%, and that was on a saturday. On that day I was at the bar with my wife, I streamed a soccer game, an ncaa basketball game(GO KU), and most of an nfl football game with my battery not dropping below 86%.I can't say anything more. It's not the prettiest thing, it is bulky, but it works like a charm. Several of my coworkers have since bought them same model.I made the right choice, and fyi......this is the first review I've ever posted about a product that I like.

Decent Battery Reserve back up which works inconjunctiuon with internal battery, but charging port is on a corner that is difficult to connect for charging . Comes with Usb Charging cable which is a plus but without the plug .

This case has its issues. You can't really tell how much battery life you have left. You can charge it every day and be pretty safe on not running out of battery. I'm not sure if this one was defective or that it was just poorly designed

Not a bad power alternative/additional power source as a whole, and I would have given it more stars but for the following reasons that you should consider before YOU buy this product: If you keep it attached to your phone all the time you will not be able to use ANY of your OEM synching/docking cables/systems/devices - you must use mini USB cable, like the one provided, in order to charge - and IT will not allow you to sync; Your previously purchased carrying cases or vehicle mounts probably won't work as this charger/case increases phone size enough to make fit very tight or unusable.
On the plus side - it does extend your battery life; it's not to bulky in the hand; and the phone mates well with the case. I would not think, however, that it could withstand long-term repeated disassembly and reassembly in order to sync your phone (unless you sync wirelessly). There are also some edges you can feel along the seams that catch your attention - but not overtly so.

Overall the case functions well and protects my phone, but the material is a little too slippery and I've almost dropped my phone several times. Also, the area where the charger plugs in doesn't allow the charging cord to seat very well. Often times I find the cord has backed out partially or completely and therefore isn't charging the phone or case.

Delivers but build quality leaves so!ethin to be desired. Multiple seams not properly sealed.

Purchased as a gift, but I installed, and the fit was veerry tight; didn't close fully. Not as simple to "turn on/off" as other units, but the flush pushbutton also does not have the risk of damage as happened to the unit it replaces.

I bought one in February. It stopped charging in May. I took it off the phone and tried charging the phone with its original charger. The phone battery charged. I then tried charging the case without the phone and it did not charge.I got another one in May and in June. It stopped charging. I tested both the charger and phone separately and found that the phone would not charge, the uNu case did charge. When I took the phone in for repair, I found that it needed a new battery which I did replace. I put the uNu case back on and it worked. Three weeks later, the phone stopped charging. I took it in to find that the charger port on the phone needed replacing. I wound up replacing the phone itself with another iPhone 4s and put it in the charger. Both charger and phone are working as expected.I am disappointed that the first uNu stopped working after three months. I'm hoping that this one lasts until September when we can inexpensively update the phone.

Unit was a great design and looked good. Installed on my I Phone 4s was easy. Just slide the 4S into the bottom piece and then slide the top piece on to phone until it clicks and you are done. Would advise charging unit prior to install because it takes 2-3 hours for a full charge. It was good on recharging phone at least 2-3 times during the day. As directed it auto charges at night when you plug it in to recharge. The negative of unit and weak point is the charging cord and plug. It was hard to get it to stay in the unit. And I made a mistake of buying what I thought was a replacement cord and plugged into the unit and damaged the female receptacle on phone and had to throw it away. Could not charge after that. There is a little micro PC Board that your plug connect to and it has to be perfect fit when you plug your charging cord in or you will damage unit........

Poor quality overall, though it does help extend battery life. I have purchased several of these in the past years, and the first one lasted the longest. Now, when I buy a replacement, I use cut pieces of Gorilla tape to tape the edges and the seems to keep it closed. I found that without the edge protection and the seams taped, the unit would disintegrate qhen dropped onto a hard surface. Now the unit is not disintegrating, it just no longer can be charged and charge the phone at the same time. The batter life is also much shorter than it was originally. Very low quality product, but I have not been able to find and decent high quality alternatives.

After a few months of using this charge case (I purchased this to replace the Mophie case that kept failing at the usb input) I noticed that the top part of the case that slides on and off began to loosen and would frequently "fall out" of its track. This began to be somewhat of an annoyance after sometime. The "silver" finish on the sides of the case began to wear off over time and no longer looked nice. It did protect my phone from several falls and drops and it did so without any damage to my phone. As far as a charger, I still use it on my old iPhone 4s that my kid beats up on a regular basis.

so far battery has provided extra life for iphone 4 just as promised.Pros:Like that the battery lights are on the back and dont flash all night long while trying to charge while sleepingsleek modern case, does add length and weight (stays in armband while running but isnt covered completely if it rains)Consdont like that it needs its own charging cordwould like it better if the bottom popped off (rather than the top) so that I could use regular Iphone car charger easily.it's also too easy to hit to the 'charge' button as it is placed on the back of the phone... several times I've activated charging by accident.all in all a good option so far. Will see how long it lasts.Update:been using it for a few days now... really feel like my phone battery is being drained by this battery case. I normally just save the extra battery for events (running marathon, vacations) but since using this as my daily case, I've had to use the extra battery almost daily. It shouldnt be causing additional drain just so I have to use it. decreasing a star.

Disadvantages:
The Battery case claimed to be 2000mAh, but with a Full-charge, it only charges up to 74% of my iPhone 4 (which is 1420 mAh, which is brand new replaced with Apple Battery)
-The charging socket is Micro-USB and very poorly designed. In a way that the cable socket easily may inplugs from the phone! Moreover, your iPhone cables would be Useless as soon as you buy this Battery case.
-Cover sizeably affected the Sound and the vibration of the phone. In a way that many times i would not realize the buzzes and rings of the call, while phone is in my pocket.
-if your phone does above 26% of bettery once you turn the Case-Battery switch on to start to charge your phone-battery, case-battery would NOT Auto-off the chargerging process once your Phone battery is fully charged and it literally drains/waste the rest of the Case-battery power.
Advantages:
-Nice outerior coating of the cover.
-LED indicator of the Cade-Battery.
-On/Off switch for the Case Battery.

i had a mophie on my previous phone, but thought I could save some money by buying this. Wrong. It's junk - the charging connection is loose, and the functionality is such that it was actually impeding my ability to keep a charged phone.
Awful.

the first one did not work, however they shipped me a new one. still having issues. my I phone 4 seats in the second one . unfortunately my phone lasts longer with out this installed. I tried charging them together, separately. no work. I have not notified the vendor. wish them luck. I don't think a 3rd unit is the answer

1st of all its not a Mophie case. A mophie would fit perfect. A mophie case would at least charge the phone to 100% from 5%. And still have more juice. This almost fits perfect. I have a iPhone 4s and the top piece doesn't fit right. Lock button would stay stuck. Which would make phone show "swipe to power off". So I used my mophie top with the new bottom.This case would charge your phone from 5% to 75% and that's it. I was better off paying $85-100 for a mophie. But this would do for now.

I've had this product for about two months and when fully charged, it doesn't charge my phone completely. It doesn't take long for the power to deplete. Also if you are charging it at night while asleep, the lights on the device are bright and will light up the room. I suggest putting a towel over it. It does, however protect my phone.....that's it.

I need to be able to remove the phone from the case to dock the phone to various speakers etc. The case is very difficult to remove once the phone is inserted. There is no 30 pin external plug on the case to attach it directly to a docking plug. Also it seems my phone loses power more quickly with the phone case installed than it did when I used no external battery power. This defeats the purpose of the charging case in my opinion. So I returned the charging case and went back to the original non-charging case, and I will use my external RAV charger instead. I do like the external LED's on the back that tell you how much charge remains in the case battery. I would prefer a one piece case which is softer and easier to remove and put on.

I loved this uNu Power DX Plus much better than my Moto which died after three years - but after less than a month the uNu extended battery won't charge although it will charge the IPhone. However I needed an extended battery for the phone not just a protective case.

Initially I loved this case, got it put my phone in it and it charged immediately! Then came time to charge the case, plugged it in and it just wouldn't charge so, decided well you must have to charge separately so, I attempted to remove my phone from the case and had a little freak out because it wouldn't budge! I actually had to take a butter knife to jimmy my phone free!! Then I plugged the case in to charge and it took 6 hours! What a waste of $39! Only positives are it looks good and does charge your phone but, who wants the hassle of having to remove your phone (and that is difficult) to charge a case for at least 6 hours! Wasted my money :( Over priced, underwelmed!

"Made with state-of-the-art technology, the DX allows users to use any function button with case one, sync and charge with the case equipped, and visualize current battery levels (of the case) via the sky-blue 4-LED battery level indicator."So says the description. 10 days later and I can no longer charge my phone; I have to charge the case, then use that to charge the phone, then charge the case. Very inconvenient. The manual says something about the case having an automatic switch that will allow your phone to charge first, then will switch to charging the case. This was true for 10 days.Quality control is.... lacking. Someone forgot to completely paint the camera lens section of the case silver, and it inexplicably fades to black. The two halves of the case have never really seamlessly fit together. Has a cheap feel to it which I was prepared to overlook, but the other issues just make the package undesirable. Will be returning it shortly.

Connector failed after 5 months, but it only took about three months to notice a considerable changes in the time it held a charge. Poorly made. Top section comes off too easily and phone slips right out after it. White effect on pictures from the glare flash off of the plastic is a hint of the design quality.

The battery life was great, however the MicroUSB charging port did not hold up. My first issue started with having to wiggle the cable, or apply downward pressure to keep the device charging. After about a month the USB guts fell out. As far as a case, it is nice, and the battery life was great when I could charge it.

This charger worked really well...for 5 months. At the 5 month mark, it started charging the phone whether or not the charge button was on red or green and then less than a week later, the charger itself wouldn't hold a charge. Now it's going in the garbage and we'll be ordering from a different company.

Buyer Beware - This is a generic battery case, designed to look like a Mophie battery case. The packaging is the same, with a few Chinese/English words here and there. I bought one and it didn't work at all, so I returned it.

This case has a major flaw in the design. While it does achieve the basic functions of providing extra battery life and protection for your phone, the plug for your charger is awkwardly located on the top corner of the case with a slight curve making it very easy for the cable to fall out during charging. Slightly touching the cable will knock it out. If you buy this product be prepared to frequently wake up to an uncharged phone. I regret purchasing this product and I do not recommend it to others.

The case looked good , and that's all I can say. The power cord would not stay in the unit and cord was to short! Bad design.......... or bad plug whatever... It took at least 3-4 hrs to fully charge unit. And could only get one charge into my 4S I phone from a 4 LED charged unit. Would not buy again!!!!

I actually really liked this product when I first got it. It charged my phone as asvertised and the case is pretty nice too. If it still worked I would have given this 5 stars. It will not charge anymore. It quit charging after a month or so. I've tried different cords and power packs thinking that might be the problem but no, It's the case.

Battery stopped taking a charge 3 days after my return window closed. Worked at 100% up until then with no hiccups. Only lasted about 6 weeks with a recharge every other day as I use my phone online a lot.

Battery seemed to charge, but did not allow connection to Iphone or allow charging of Iphone by cord. Would not indicate further charging of case alone. Seems to have been a connection problem. Returned for refund. Not willing to try again.

It seemed to work for a day and then problems occurred. The first day it worked fine. Then it would work on some of my charges but not others.Now it no longer charges the phone when connected to a USB power source. The last couple of days I have to take out the iPhone and charge it separately to charging the power pack.

Product stops functioning after 2 weeks. It will not charge. Besides, it is very difficult to detach iPhone 4 from it. I would not buy it again.

This was probably a good charger case before Apples recent IPhone 4s software upgrade, or so the "Genius Bar" at the Apple store informs me but I bought this case after I upgraded the software in the phone and not only did it not charge my phone but it was depleting the charge my phone had. The charger itself was fully charged at the time too. My IPhone 4s is back in its Otter Box" and the uNu has been returned.

I like the product...alright. The top of the case comes away from the bottom, on occasion. A light touch of hot glue or a very light adhesive works fine to keep it in place. I'm not fond of when you unplug it from the charging cord, it automatically defaults to the charge mode. Also, there are four LED charge indicator lights on the back of the unit, one has never worked.This unit is much thicker than my old Mophie and gives my iPhone the same hour usage. My Mophie was only 1700MAh and this one is rated @ 2400MAh. Something does not jibe. All and all...it's O.K....for the price.06/29/2013-Update: It died. Doesn't charge. Returning immediately.
