sntrack

Tracks the battery discharge rate during sleep.

Description

The script is executed automatically on sleep enter and exit and persists the current timestamp and energy level in a database.

This data can be later used to calculate and plot the discharge rate.

Requirements

• python3 and the following modules
  • matplotlib for plotting historical data
• systemd for automatic execution on sleep enter and exit

Installation

• copy the script main.py to /usr/local/bin/sntrack and mark it as executable
• place a symlink of the script /usr/local/bin/sntrack to the directory /usr/lib/systemd/system-sleep/

Usage

While using a battery as the power source, suspend and wake the system. Run sntrack plot to plot the recorded data.

Short sleep durations are discarded by default.

For more information see the output of the command sntrack -h.
