Ok, more stuff on TODO list. I actually use python hacks, and not libbattery now. Is this one correct? voltage_min_design:3100000 I believe you mentioned flash stops working at 3.3V. What is important from my point of view is to shut the system down when the battery is low. I believe that still needs to be implemented. Is it appropriate to shutdown at POWER_SUPPLY_CAPACITY_LEVEL_CRITICAL? But then libbattery will race with shutdown to save the thresholds... I also have some hacks to allow configuration of the full voltage. Charging to 4.35V is pretty agressive, and I believe baterry will be damaged less if we only charge to 4.1V.
