Tokolozi , Jan 2, 2021 : Usually this is caused by background apps. Battery statistics would be needed to figure out what is causing it. AOD can also cause additional drain of the battery. About 1% an hour sound about normal to be honest.

If it's low (say <110dBm), this can REALLY drain your battery, pretty much ANY mobiles' battery. It's a LONG industry problem, going back to the very beginning, pretty much...
