Hi I just bought iPhone 5s a week ago.
I checked the battery cycle count were 170, the full capacity of the battery is 1600.
Now the cycle count is 189 but the full capacity has dropped to 1500.
Is it normal?
Thanks, cheers
iPhone 5s, iOS 9.3.2
Which app are you using to measure? I don't think Apple has any app for that?
Regardless what the app says, do you see actual degradation in battery life or performance? Get to the Apple Store where you bought it and ask, you are in the two week period of return without asking
I used iBackup for pc. It told me about the battery cycle count
I was asking because the SDK and APIs of iOS do not expose battery as Android does, so those measures are difficult to be accurate since they don't really have access to the core battery management. Anyway, I think it's worth reviewing how many apps you have in Settings > General > Background App Refresh and how many services open like GPS, location, bluetooth, mobile data and wifi and others you could be using at the same time (i.e: mobile data and wifi, turn one of them off) to maximize battery life.
