The battery in my Iphone would not hold a charge and would shut off when the the level dropped to around 85%.
First replaced the battery with one I purchased from another site. It lasted about 2Hrs. When I tried to charge it, no such luck. I then did some research and found the IFIXIT site with other stories about buying the wrong replacement. I ordered you battery and it had the exact number of the OEM. The replace ment was pretty easy and I'm satisfied with the results.
Do your homework before buying from the web. I didn't get my money back for the 1st battery.
