Pine Phone Battery Issue

Other distros don't seem to be doing this. Did you see any difference in behaviour between distros?

Depending on whether the phone is suspending, and what power state the modem is going into, you could see long or short battery life. Assuming there's nothing faulty, a few hours suggests the modem is in a high power state, and the main cpu isn't suspending - and possibly that the display is kept on. The back of the phone being warm an inch or so below the camera would be indicative of the modem using a lot of power. If your phone is cool and the screen is off, but the battery life is still short, something odd is happening.

Random charge level reporting seems odd - I've not seen that, so it may indicate a fault. I'm not familiar enough with the battery management hardware to narrow it down though.

Thank you very much, this is a very nice guidance. I don't have the phone on hand right now (I'm not at home), and will try to see more deeply ASAP.
IIRC, I didn't see hi cpu usage on  'top', but since the modem is device related, I don't expect to see it there. I will investigate on interrupt request usage next time. Finally yes, the phone was hot (not too much, but like with a 100% cpu usage).  I didn't notice any difference in behavior btw distros, but I will put a more accurate eye next time.
Once again, many thanks for your tips, great. I will come back next week,
