From one day to another I saw that my battery had an very high battery drain when connected to an powersupply via USB. I use the App "Battery charge limiter" which allows me to see the battery drain, because I can stop charging while on power supply. With another App i have found out, that the power supply prevents the device from going to deep sleep. So far I disabled all Apps in connection with the battery, wiped cache twice and updated the OxygenOS. The problem is still there. Does somebody know a solution for this or at least a workaround?
