**Hi,
I own a Fairphone 4 with /e/ OS, now on official v. 3.5, I have two batteries and recently I observed that after every battery swap, the maximal capacity displayed in Battery** → Informations about battery is set back to 100% (the same as fabric capacity).
By the way, I’m not sure if the Health of the battery is measured the proper way, as one of my two batteries is extremely exploited (after running BOINC on it for 3 years when phone was unused), and when I use that battery, the Health is displayed as “Good” anyway, whereas some other apps claim that battery has 1600-2000 mAh left from the original 3905 mAh, and when that battery reaches ~20%, sometimes it drops from 20% to 1-3% in one or a few seconds instantly, so that battery is surely not healthy, I use it as a substitute for powerbank after I have bought the new one.
Best wishes
