The device got normally discharged until bme shuts down. Screen always on and full brightness, the process took some 4..5h from a full battery to shutdown. Below you see tail of log created by a slightly modified bq27200.sh 5, as c&p from PC ssh session.
Watch the bq27200 chip learn immediately prior to bme shutdown. The period time for one logline was 5 seconds.
It's quite unlikely bme just incidentally shut down the device exactly same moment the bq27200 reached EDV1 battery threshold of 3248mV and thus learnt about true battery capacity. Also note about the remaining ~17..20min until battery would reach EDVF, the final discharge voltage at which the device should shut down unconditionally
