charge-control allows controlling battery charge to avoid overstressing the battery with full charges or full discharges. The script requires root permissions.

How to use

Just download the script and make it executable with chmod +x /path/to/charge-control, then run it with sudo:

Usage: sudo ./charge-control [-d DEACTIVATION] [-r REACTIVATION] [-f FREQUENCY] [-p POWEROFF] [-a ANIMATION]

Options:
  -d DEACTIVATION: battery percentage at which charge is disabled (default: 90)
  -r REACTIVATION: battery percentage at which charge is enabled (default: 75)
  -f FREQUENCY: monitoring frequency of battery level (default: 10s)
  -p POWEROFF: battery percentage at which the device is powered off (default: 10)
  -a ANIMATION: monitoring animation, 1, 2, 3 or 4, in decreasing CPU usage order (default: 2)
  -h: show this help

All arguments are optional. Values can be provided as positional arguments in that order
if not prefixed with flags, or provided in any order if prefixed with flags.

Example output

  Auto power-off level: 10%

  ▪ Charge disabled until battery drops to 75% (21:02)
