Hi guys. I registered so i could ask you for some help regarding my iPhone 5's battery life. I bought it in February 2013 and now I am seeing some bad battery life. Starting, today i JB my phone to install Batterylife and see how the battery was: Capacity: 990/1430mAh (69%). 525 cicles. Not only is the battery draining fast, but it also turns off when there is supposedly ~30%. I can wait a little and then it will turn on, for a while, until turning itself off again. It does this until I charge it or until it actually dies. Yesterday, for instance, it was around 5pm and started having this problem. It has become really annoying. Some guys told me that it could also be the logic board. I hope it isn't as that would be very expensive to repair. I was thinking on replacing the battery myself, but I'm afraid I will buy a non-Apple battery. (I live in Argentina, where there is no official apple support). Thanks. EDIT: Btw, i did a DFU restore and i tried callibrating the battery.
