Battery Guru, from developer Paget96, is a detailed battery monitoring app for Android. It estimates the capacity your battery has left and keeps a close eye on charging sessions, heat and drain. If you are weighing up a Battery Guru alternative, this page compares it with bCare feature by feature as of November 2026, using Battery Guru's official Google Play listing.
The short version
The two apps overlap a lot. Both estimate capacity in mAh from your own charges, count cycles, show live charging current, rank apps by battery use and offer full charge, low battery and temperature alarms. Battery Guru goes deeper on statistics and reports. bCare adds things that reach beyond the one phone in your hand: linked family phones, Bluetooth device levels, and an alarm-ready check aimed at phones that stop background apps.
bCare vs Battery Guru feature comparison
The Battery Guru column only reflects what its official Google Play listing says as of November 2026. Where the listing does not describe a feature, the cell says Not confirmed. That does not mean the app lacks it, only that we could not verify it from an official source.

What Battery Guru does well
- Transparent health readings. It shows estimated capacity beside the design capacity and labels each reading by confidence, from Learning to Verified, so you know how much weight to give a number. It can use the phone's own health figure where one exists.
- Rich charging detail. While the phone charges it shows current, power and voltage as they change, rates the charging speed, estimates time to full, scores every session out of 100 and sums it up, peak power and temperature included, once you unplug.
- Drain insight. It tracks how long the screen stays on and off, how much time the phone spends in deep sleep and how much charge goes overnight, and it warns you when drain climbs well past your usual level.
- Reports and exports. Weekly summaries, a history of past sessions, PDF reports, CSV exports and backups that can be encrypted.
- Lots of widgets. Eleven of them, so charge level, health, heat, power use and time left can all sit on your home screen.
- Two-cell phones. Settings for phones whose battery is split into two cells.
If you like to dig into numbers, export them and see trends week by week, Battery Guru covers a lot of ground.
Where bCare is different
bCare covers the same basics, and puts its extra effort into alarms that ring reliably and into the other devices around you.
- Alarm-ready check. Some phones close background apps to save power, which can silence an alarm. bCare walks you through notifications, battery optimisation and autostart, then plays a test alarm, so your battery full alarm, 80% charge alarm and low battery alarm ring when they should. Each has repeat, snooze, voice announcement and the option to ring on silent.
- Simple heat limit. The overheat alert rings when the battery passes a temperature you set between 35 and 50 °C, 42 °C by default.
- One health score. The battery health check measures capacity in mAh from charges of about 20% to 80%, counts cycles and folds them into a single 0-100 score, with the habits wearing your battery listed below it.
- Family phones. Link family members' Android phones by QR code with family devices and see their battery on your screen, with an alert when one runs low or goes offline.
- Bluetooth devices. See the level of your connected earbuds, watch or speaker, shown as one level per device, with a low battery alert.
- Charger check. The charger test compares each new charger or cable with the last one you used.
- Drain and looks. Apps draining battery ranks apps by share of screen time over 7 days. Seven battery widgets and six charging animation styles cover the home and lock screen.
bCare also offers reminders to charge before calendar events and a drive mode. It is available in 15 languages and has 100K+ downloads on Google Play. Charge alarms, live readings and temperature alerts are free; an optional PRO subscription removes ads and adds extras.
Which should you choose?
- Choose Battery Guru if you want the most statistics in one place: confidence-labelled health readings, per-charge scores, overnight drain reports, weekly summaries, exports and a large set of widgets.
- Choose bCare if you want alarms you can count on, a single health score that is easy to read, and battery levels for family phones and Bluetooth devices next to your own.
Both are free to install; health estimates in both need a few charges to settle. Comparing AccuBattery too? See our AccuBattery comparison or browse all app comparisons.
