I have done all of this multiple times and the battery drain continues. It started with the July 2023 security update and has been happening ever since. I noticed that if I disable Google Play Services the drain stops, also if I disable location the drain stops. The drain also continues in Safe Mode, when all installed apps are disabled. I have set location to Ask or only while using the app for every app I can including system apps. How can I find what is really causing this and finally fix it. The actual drain is about 2+% per hour so in a typical day, 50% of my battery is simply used by Play Services without doing anything at all. All sync or location options are off.
