Android shows you the basics. Battery Guru goes deeper.
Get your actual battery capacity in mAh, track health degradation over time, measure real charging current, monitor temperature and see everything on an always-on display or homescreen widget. Battery Guru builds on top of Android to give you the full picture.

Recent changes: Battery health is more accurate. Fixed the health number jumping far above the graph, reading twice as high on phones with two cells, and staying stuck too low.
The battery percentage now always matches the one your phone shows.
Fixed the first widget colour option doing nothing.
No more full screen ad when you reopen the app.
Also fixed the charging summary going missing, and a battery below freezing reading as 0 degrees.

Comments on Battery Guru: Battery Health for Android
★★★★☆G· Aug 20, 2026
Very good competitor to accurately. Just one recommendation, make SOT easier to read. For example, in session history you can show SOT for every session directly on the list, much easier that way. I feel I need to dig too much to find the SOT.
★★★★★Shaun Carolan· Sep 3, 2026
The app keeps getting better, lots of detailed info about the battery, and it's overall health and charging stats. Love that it can tell me what type of charge I'm getting too. Amazing work!
★★★★★Jeremy Lavender· Aug 23, 2026
Seems to be providing good battery health readings, over heating alarm and rates the gentleness of charging for improved battery health.
★★★★☆Abdulsemiu· Aug 2, 2026
A good battery and charging monitor app, there are ads but not intrusive
★★☆☆☆Deano· Aug 3, 2026
I've decided to uninstall the app. Too many bells and whistles, which makes the app more unintuitive with every update. Also the app is using too much of my mobile data, even though I only open the actual app when I'm connected to Wi-Fi. 94 MB in 12 days. The other popular battery app only used 1 MB! Mobile data is not cheap outside a data bundle, so I'm afraid I have no choice but to uninstall 😔

Very faulty readings and information. Reports wrong information compared with real test and factual information
★☆☆☆☆RC· Aug 5, 2026
I wish they had a separate thing for screen off and deep sleep in the previous version, but no, now screen on, screen off all together in one menu. I have to click again to see screen on time. Why don't you make this simple? Screen on: x hours xx minutes screen off (without deep sleep): x hours Move the deep sleep to another sub menu. I don't want to see hours off battery life just to realize 80% of it is deep sleep.

was one of the best, but now there is full screen unskiable ads also less accurate than before
