Prepare the Termux workspace
Open Termux in the Academy root and prepare this lab with the local companion. It creates safe samples, notes and evidence files under your Termux account.
python Smartphone-Academy.py prepare battery-drain-evidenceNo root. Keep the workspace under $HOME and avoid personal identifiers in evidence.Practical mission
- Record battery level, temperature, screen state and network conditions
- Run two controlled usage periods with only one planned difference
- Compare Android battery statistics with your own timestamped notes
- Identify likely causes, alternative explanations and safe next tests
A battery investigation report with test conditions, observations and confidence limits.

Analyst reflection
Which result from “Identify likely causes, alternative explanations and safe next tests” needs stronger evidence before it can support a real decision?
After checking the evidence, run python Smartphone-Academy.py complete battery-drain-evidence. Progress is stored locally in the Termux home directory.
