Frequently asked questions
Does Battery Snitch need root?
No. It uses Android's built-in usage-access permission to detect background battery drain — no root, no custom ROM, no risky hacks.
Is it really free?
Yes. Drain detection, alerts, the Charger Lab and the Hall of Shame are free. An optional Pro+ subscription unlocks advanced analytics and power-user tools.
Will it drain my battery itself?
No — the opposite. Battery Snitch runs lightweight periodic scans and is designed to save far more battery than it uses.
Do you collect my personal data?
There's no account and no login. Your app usage is analysed on your device. Only anonymous, aggregated app-drain numbers are shared to power the global Hall of Shame. See our Privacy Policy.
