On my old android, I used AccuBattery but now I’d prefer an open source alternative. I’ve seen Battery Bot and another called Plus Plus Battery. The former is really old, last updated like 3 years ago and the latter seems like it is in early stage and built for a few brands in particular. What apps do you use to keep track of battery health?

What I’m looking for is keeping track of battery health like AccuBattery does, monitoring charging and discharging cycles, time remaining etc. Basically everything that AccuBattery does. Any ideas?
