Recently I've thought my battery seems to be dying much quicker than it used to, and my iPhone 5S is nearly a year old. Seems about right. I chatted with Apple online, they received diagnostic info, and told me the battery is fine. Then, I downloaded the iBackupBot app to get the real numbers, and it says my battery has 283 cycles, original capacity of 1550, and current capacity of 1500. Does that seem right, or even possible? I'd expect a much lower current capacity after 283 cycles, so I'm wondering if the numbers Apple got are even correct. I don't want to go to the Genius Bar unless I know my battery is worn/defective, so I'm trying to get more insight. Does it seem like my phone is reporting incorrect info on the battery?
