Is it possible to run a command in adb shell, dumpsys perhaps that will show the power on off dates and times from a year ago ?
I have run dumpsys and it has created a huge file with loads, 100's of thousands of records in a file - what text should I search for ?
I have tried searching for shutdown, power, reboot and some date strings when I know it was last turned off "2023-02-26 19" and "2023-02-26 20", and have found entries, but there is no textual description to say whether it is a power off of the phone for example:
