I've been using some Bluetooth peripherals lately which has meant I've been charging my phone two or three times a week. Consequently, Peak Performance has now dropped to 95%. I suppose that's still pretty good for sixteen months. Also, I need to keep the following in mind:

  • Apple claims a 20% for 500 cycles.
  • Assuming I charge about 50 cycles in 60 days (two months).
  • That's roughly a 2% loss for 2 months usage.

I'm nowhere near that so I think the battery is still doing fine.
