I'm looking for an app to check which app is using my battery mostly. I've a Huawei P20 on EML-L09 but I debloadet it and mostly F-Droid apps are in use. Unfortunatly the OS itself don't show me values wich are useful ( <1 sec/<1mAh for every installed app ). Can someone recoment an app to me to find my drainhole? I have a guess (AdAway) but I´m not for sure. I already have a replacement battery which work fine the last 6 month. So this shouldn't be the issue.
