Firmware update on battery power

The firmware update was executed automatically on battery power - which is a remarkable. Power loss during a firmware update usually is fatal - causing a corrupted software version in flash memory. There was no notification to connect external power - which is normal when updating software stored in flash memory aka firmware memory.
