To make long story short - there is an apparent bug in 10.1 software (e.g. .273, .2354) that messes up battery percentage counter - sometimes phones shut off at e.g. 15-20-30% indicated and do not charge fully (till eg. 85% - 90%).
Battery health and life seems ok, so this is software issue that needs to be taken care of.

It's actually a discrpency between the actual calcualated battery remaining power and the on-device battery meter.
It's happened on the legacy BBOS device and other Z10 OS releases.
Usually, this can be reset when your device is down to 15-20% charge, by leaving your Z10 to charge with the OEM wall charger, and with the charger STILL connected, remove the battery, reinsert, reboot, etc. You can also try this with a simple top edge power button Restart.
It may take a time or three of doing over the 2-3 days, but it normally works to correct the "reading" of the on-device battery meter.
