What shud be the battery health for Note 9 after 16 months usage? Mine is showing 78% on accu battery app. Anyone suggest? Anyone knows abt benchmark for battery health % after 16 months of usage?
Battery performance dipped drastically after Nov update. Battery draining in night upto 10% drop on power saving mode. I mean goes down to 90% by morning in 8 hours if full charged in night. Wifi/data off in night.
