I recently bought a used iPhone 12 about 10 days ago. The battery health was at 91% when I checked, and the seller confirmed it was 91%. After he flashed the phone, the battery health went up to 93%. However, in just a week and a half, the battery health has dropped back down to 91% and I usually charge it to around 80%. I'm concerned—will it continue to drop like this?

Honestly, it might be helpful to just use your phone normally and stop checking the battery health so obsessively. It fluctuates a bit and might even stabilize after a while. Just enjoy your device!

But I'm still a bit worried if it's gonna keep going down. Do you think this is normal?
