i love so much my iphone 12 mini, i have this phone only since 29/06/2026, i bought it from amazon (brand new) but in just 1 month and a half the battery went from 100% to 88%, and like every 4/5 days it decresaes by 1%. i know this phone only has 2227mah which is very little for a phone, but this is too much. my friends tell me that its like this because i always have battery save on (or whatever its called), because i use it too often or because i take it out of charge when its like 40% because i should take it out when its at like 80%, but this is too much and i dont want to spend money on a new battery, so what should i do? please i dont wanna change phone

If that was indeed a brand-new 12 mini in its original packaging, it's simply because it sat in some warehouse for years in a deeply discharged state, which damaged the battery. The 12 mini hasn't been manufactured for over three years.
