worsening battery health
Hey, so i have my iphone 17 pro since october 24th 2025 and since that day i use a 5w charger (less heat/overcharging), optimized battery charging, never let it under 15%.
Im now at 257 cycle counts, at 225 it dropped to 99%, but now after around 30 cycles later it dropped further to 97%.
just how? I take so good care of my phone and battery and it just dropped so fast.
Any explanation or what to do now?
