Chosen Solution
Hi, My partner’s SE battery was ‘replaced’ by Apple ‘under warranty’ in Dec-19, when coconut battery was showing 88% of design capacity. The ‘genius’ said “that’s normal wear”, but I told him I would pay anyway to have it changed. It was with them for a couple of days before we picked it up again, and I was told my another genius that I would not be charged for it. I didn’t think to redo the Coconut Battery after the replacement or check the battery health. Skip forward to Apr-20, and my partner is upgrading. So I restored the phone, and out of interest, downloaded coconut battery again, but it’s saying the battery is now 1,027 days old, has done 527 cycles, and is 85% of its original capacity. For accuracy, I downloaded iMazing which shows 88%, and the iPhone’s software shows 90%. My question is if Coconut Battery’s results are correct, it is impossible that the battery has done 527 cycles in 6 months, and would imply from the age that they never actually replaced it. This would explain their generosity in affording me a ‘free replacement’. If the numbers are correct, I’ll replace it myself as I have done 3 times now for my old 5s. Thanks in advance.
Did you pay for the service? You imply no. So its likely they didn’t open your phone. Why would they swap batteries? Its more likely you got someone elses phone. Did you check the phones S/N? Did it have everything on it before you gave it to them? If the S/N’s match and the apps and data are untouched (assuming you didn’t do a recovery) then your partners phone is the what you have you just didn’t notice the cycle count. Your habits on letting the phone to discharge to a point the cycle count tick off then is the issue. Do you charge it every night? Or at least every other night and you don’t let the battery to discharge less than 1/3 that often. What does Battery Health tell you? iPhone Battery and Performance
