Yesterday my phone was quite hot all day and battery drain very fast. Then I noticed there was Bluetooth on. I didn’t put it on. Maybe it went on accidentally.
But is is normally that battery drain very fast and phone gets hot when Bluetooth is on and not connected to any device. Maybe it try search connections all the time.
No.
Obviously some process ran wild, using all CPU.
Troubleshooting - do our docs have a general/initial troubleshooting section? Couldn’t find one just now.
Are you familiar with the Linux command line? If not, install a process monitor app like Lighthouse.
Thank you for the link. Didn’t know it before. I know command line. My computer had Debian OS. I will examine Lighthouse.
