Update: It only seems to happen when phone stays plugged for some time (4h) after end of charge. Then it stays for a while at 100%, and drops suddenly from 10%. Problem disappears if phone is unplugged within 2h after full charge. So maybe a calibration problem, but possibly without solution due to changing battery parameters (voltage for energy, etc...).

This has happened twice in a row already, and probably will systematically. Battery warning means I need to plug in instantly to avoid shutdown. There seems to be no way to calibrate battery measurements, or set a different warning level. I have no idea where to get log history for battery level, but I'll do it if someone gives me directions.
