My battery capacity according to my system(evolution X) as well as as accu battery app, and when it turns off when It hits 0% when I tried to recalibrate it, dropps really really quickly. 4days ago a had 2675mah and now I have 2135mah…. Is that normal ?
Total battery capacity usually doesn’t drop that fast. Try resetting your phone to remove any faulty drivers or malware that can interfere with good battery reading. If that doesn’t work, replace the battery. The link below has how-to instructions: Xiaomi Mi 9 Battery Replacement
