Replacement 3.7V 1200mAh Lithium Polymer Rechargeable Battery with Tools for iPhone 3G

Pros: The battery comes with a screw driver and plastic tool. After installation the battery worked fine, although the original Apple battery was better in the beginning, it was a big performance improvement over the old one (1,5 year old). Battery fitted as well as the original one.

Cons: The instruction that is added is not the best one. Google and download a better one.

Other: Cheap and effective way to extend the lifetime of you old 3G iPhone. The replacement procedure is not easy; You have to remove 6 cables and 10 screws and put them back in the same order. It took me about 1/2 an hour, including the cleaning of the inner parts.

Pros: Decent replacement to my dying 3 year old battery, nothing special, you still have to recharge the battery every day, but that could be bacause the device is too much fun. Left the phone with its new battery on the table for 2 weeks, checked it later, it showed about 70-80% left, 3g was on the whole time.

Cons: Insanely hard to replace, did it myself. I'm not a noob to this kind of stuff but when the old battery was out and all whst was left is to put the new one in I already said goobye to my phone, but to my surprise it turned on and worked. Camera didn't work but i think i didn't connect the cable or just didn't press on it hard enough. Tools that came with the battery were useless, broke right away, used my own.

Other: Will be back in a year or two for the battery for my iphone 4...

Pros: The price is very good for the state I live in. I had a battery which fully charged lasted 5 hours,I bought this one and now lasts for two to two and a half days with one charge.

Cons: It still lacks power that original new battery has. It holds on iphone which is broken by putting firmware 6.15.00,that firmware uses a lot of power from iphone even in idle so the battery is not so bad if you need two days of work with iphone.

Other: So maybe not perfect but it is solid built, has the power to restore your iphone for more work with it than drained out old battery. If stuck on 6.15.00 buy this and you will have two days of work,better than 5 hours if your battery is like mine was.

Pros: For me replacement really works and capacity of the battery is good, the replacement process was easy for me. I am actually using it and no bigger problem I havent found. Also the temperature is accetable.

Cons: Worse materials, lower time of use with it, wrong percentage shown sometimes on iPhone but it doesnt make any problem.

Other: Its a real replacement and price is really good think someone who needs it can buy it...
