BetterBattery - v1.0 BETA - Preview
Accurately observes battery percentage in real time

The app is still experimental, it tries its best to run on all android phones. It worked on my A14

Relies on current_now, charge_counter, level, capacity and other props in addition to pure Android Java and Math. Similar to batt.py in terms of functionality but not hardcoded for one device.
