Since the upgrade to Android 13 to me it seems like a higher battery consumption.
Battery usage also tells the Android OS always is on top!
I ordered and installed a new battery pack, and it got better.
But still a lot af consumption: 25% less in flight mode after 15h doing nothing,
Maybe this could give a hint:
I noticet hat without beeing connected
a notification message from USB popping up every now and then.
When tapping in you can see that under
“Device that controls the USB connection” the
“Connected Device” flickers on and off.
Any other ideas or suggestions?
