User Reviews

GSam Battery Monitor delivers deep battery analytics (per-app usage, wakelocks) and helps identify power drains, even on non-rooted devices via ADB. It’s readable with useful widgets and has a long, active history. However, users cite ads/upsell, the need for ADB/root for full data, data inaccuracies, stability issues on some Android versions, and UI polish concerns.

Pros

Detailed per-app battery usage, wakelocks, and background activity insights.
Helps identify power-draining apps and optimize battery life.
Provides data via ADB, enabling advanced stats on non-rooted devices.
Readable, straightforward data with useful widgets.
Long‑standing, actively developed tool trusted by many users.

Cons

Ad-supported with upselling; pro upgrade is required for full features.
Requires ADB/root access to unlock full statistics, adding setup friction.

The app can't handle extended stats in Android 16 along with smart charging: it shows negative values and values above 100%. It's basically unusable. Now to the old issues: 1. Shows the wrong sign for both charging (-) and discharging (+): it's been happening for over five years already. Looks like no one really cares about anonymous usage statistics. 2. Lacks AMOLED (true blacks) theme. 3. It must request Phone permissions and it doesn't otherwise Telephony battery use is not shown.

Works well but unfortunately the android updates mean I can't see which specific apps use what percentage of battery use. I do love the widget though!

He*****, 2026-06-05

It crashes at least once a day sometimes more. That makes me question how accurate it really is. I'll uninstall and try some other apps. I'm disappointed since I've heard for years how great this app is at helping to find battery hungry apps.
