Genuine Replacement 1420mAh Battery for iPhone 4 - Black

Pros: This is a perfect replacement for the original battery. It looks well built and up to the specs of the original one. iFixit has a full guide on replacing the battery step by step. And best of all it is done at a fraction of the cost you would normally pay at a 'repair centre'

Cons: It should come with a new placement two sided sticker. As you remove the old battery the is a strong chance to damage the previous sticker.

Other: So far it has been in the phone(s) for over a month. It has restored the original capacity and time of the original battery

Pros: Perfect way to revive your iphone 4 to a good as new condition! Exact same part as the current battery in the iPhone.

Cons: none, unless your pair of hands are not steady enough. The little flexy cable needs to be folded slightly so as to fit in nicely

Other: perfect way to keep that iPhone 4 going for another year! all for less than USD 10! Don't need to upgrade to iphone 5 so you won't be bothered by the new stupid connector.

Pros: The price is very attractive I have added it to my first generation of iPhone 4 10 days ago and this battery works perfectly I have done about 20 cycles, the battery does not heat while charging The time to charge is the same as with the original battery The phone lasts about 1 day, the same thing that 1 year ago with the original battery. The battery does not heat in normal use. I recommand this product.

Cons: No cons at all.

Other: Nothing special to add.

Pros: Cheap. Looks like the original. Perfect fit. Seems of reasonable quality.

Cons: Probably not genuine replacement part.

Other: Need a replacement battery for your iPhone 4? Buy this. There are cheaper replacements out there but you never really know what you're going to get. Rely on this.

Pros: Easy to install, battery life is the same as an original battery, very cheap. Great shipping delay (24h), recieved in just one week (shipping to France)

Cons: The tools aren't included, which makes the incredible price. The packaging is just a plastic bag The informations about the battery in the iPhone settings menu are wrong

Other: Good quality, perfect product. The best battery available at DX

Pros: It looks like the original product and it fits perfectly in the iPhone. The connector also was of good quality. Now the original capacity of the battery is back again. Cheap and easy fix!

Cons: No cons, great product!

Other: Cheap way to get the battery life back like it was out of the box.

Pros: the price ofcourse is good, but there are cheaper products running. though, the quality is extraordinary. it works just as fine as a new apple battery.

Cons: when installing the product into a device, it didn't fit. A little piece of metal was somewhere it shouldn't be and so the battery didn't fit. I first needed to saw it out before i could continue the installation.

Other: a very usefull and high quality product. a good replacement for a broken original battery for iphone 4

Pros: It looks, feels like the original Iphone battery. And it holds power just as good as if you bought a brand new iphone.. Easy to install if you have a little technical knowgle. Worth the money, cheap solution to make ur phones battery work like it was new again..

Cons: It does not include any asemblin tool to install the battery. but you can buy that seperatly on dx, or maybe get borrow it from your local phone store..

Other: Buy it, enjoy it, love it

Pros: A cheap battery. Reasonably decent build quality given its price. Installation went without a hitch, connector quality is good.

Cons: Runs a bit warm during charging and usage compared to the stock Apple battery, but nothing over-the-top. In terms of battery capacity it seems to be lower than that of the stock battery; my phone lasted about 16-18 hours with this (little to no usage) compared to about a day and a half with the stock battery. Nothing to shout about here. My battery came in having clocked 195 charge cycles, which is slightly curious since it is supposed to be new.

Other: If you're looking for a cheap and decent battery, you can't go wrong with this. Don't keep your hopes too high, because this battery will probably not last as long as the one which originally came with your phone.

Pros: Works great, no problem! I have a couple of these now, and they always worked for me! It´s totally worth its price! In europe you have to pay three times for the same.

Cons: Nope, nothing bad to say. Can´t say anything bad for a product that costs 4,99, and works.

Other: Dx has allways worked well, and delivery took about one week to Finland! And also free shipping is nice!
