how long das you battery last?

Batteries is batteries. Who knows why these things happen? But they do. I don’t check battery health any more. I’ve no idea what it is on my SE2, bought mid-2021. When the battery obviously affects performance adversely, I’ll replace it.

You trippin dawg, don’t drain it below 30% and you’ll be fine

how much are you charging it? are you using it as a main phone?

Completely normal. My iPhone 13 was at 100% for 7 months and then on the 8th month, it went down 2%. The Apple battery health indicator is false and does not provide an accurate reading.
