Rated 2 out of 5 by from Too fiddly to charge both I bought this for my wife, so it needed the WAF. After 2 weeks, she still couldn't figure out a reliable way to charge both case and phone at the same time. I know there's been chatter here on plugging it in, then pressing the power button on the case to get the phone charging too. Well - didn't work. I also tried letting the case charge a bit first.. etc. etc. Never found a reliable way that meant both phone and case would be charged in the morning. That's the killer. It also offers little protection from a drop (especially face first), and you need a key or strong fingernail to press the release button to remove it

Rated 1 out of 5 by from not good Seemed robust and well designed. First time used it charged phone (albeit during use) to 70%. Second time it switched on for 10 seconds, switched off then refused to turn back on. Device was fully charged (3 led's) on both occasions. Either ive been unlucky with this one, or its overpriced tat. Plan to take back and get a decent external backup.

Rated 5 out of 5 by from Worth the price I bought this product to try it and liked so much that I bought a second one. The market leader (Morphie) costs about Ј80-90 and still only 2000mHa. You can therefore buy two of this model and outdo the the Morphie by 50%! I normally use it permanently switched through to the phone so that the 4S continually shows a 100% charge. When at home I simply plug the combined phone-battery unit into a charger and keep it/them on charge. I find that as long as the backup hasn't run down too low, both can be charged at the same time. If, however, the charge in the backup is low (e.g. only one light shows when plugged into a charger), the backup has to be charged alone. As long as at least two lights are showing, you can charge both together. If I am out for, say, half a day, then the combined iPhone plus backup will last the course (unless I do a lot of work with it). For a whole day out, the replacement as well may be necessary. (I also have another portable charger I can take with me.) There are now plenty of portable chargers on the market, some of which, no bigger than a small wallet, will charge your iPhone 4S several times over. So why bother with this product? Well, because it fits on the phone, adding very little to the size and weight, very much a fit-it-and-forget-it device. Another reason why I like this product is because it makes the iPhone safer to handle. The bare phone is slim and slippery and easy to drop. The backup battery makes it less slippery and chunkier to hold. I would say this is Ј20.99 (or Ј41.98!) well spent.

Rated 1 out of 5 by from Last one in the shop - now I know why Took at least 3 hours to charge (didn't time it as after three hours, I went to bed!) That in itself is not a problem as it is USB after all. However, the fact that it only charged the phone for approximately 2 secs before switching itself off is a BIG problem, it will be going back for a refund - I don't want another, even if there are some left in stock somewhere. The second was given because the principle of the design is great. Avoid.

Rated 4 out of 5 by from I have owned this case for over a month now and am really happy with it, below are the key points I was looking for while shopping and things I've since found with it. Size - this case pretty much doubles the thickness of your phone, this was an issue for me to begin with but I have since found it easier to hold than an un-cased iPhone and with its rubbery texture, it is also more difficult to drop as I find my phone has an almost 'soapy' feel to it without a case. As all of my previous cases obscured the lens in some way, I was concerned that the thickness of this case would do the same and was pleasantly surprised to discover that there are no interfearences what so ever, not even glare from the kudos to the designer. Design - this is a bulky case but sits flush to the face of the phone which looks great, this does however mean that it offers no protection to the screen so I'd recommend still getting a film cover for it. There are vents by the speaker and mouth piece and I have found little/no change to the sound quality and volume. As the apple charging slot is taken, there is a mini USB cable provided for charging this case and the even links to iTunes when plugged into your computer (as long as it is in charging mode) but I have found this connection to be unreliable and instead opt to remove my phone from its case when linking to iTunes. Issues - apart from no longer being able to dock it to my bedside radio without first removing the case...which by the way locks very tightly and requires a coin or something similar to open as it is very rigid...I have found no issues with it, the obvious ones such as its size I have grown used to so it is no longer an issue. I would say that it does not double the lifespan of the battery but does give it around 60% more juice meaning that I no longer have to worry about carrying my charger around with me on an average day at work (which for me is up to 16hrs). There is a warning on the box about signal and wifi being affected by this case but I have not found this to be the case at all. When charging at night, you need to remember to press the charge button on the case or it will only recharge the case battery and not the phone but trust only make that mistake a couple of times before learning your lesson. I really do like this gadget overall and have recommended it to many friends, it's a real bargain for its price too.

The battery on my iPhone is pretty well shot, only holding charge for a couple of hours. Does the Power Case operate as an auxiliary battery or is it designed to recharge the phone battery? 

Asked by: Dead Battery
This recharges the battery inside your iPhone, it that battery is not functioning correctly then the item would be of little use.
