PBH - Phone battery health

Battery health monitor: real capacity in mAh, wear and live power draw. No root.

PBH shows how much of its original capacity your phone's battery still has.

It reads the fuel gauge chip inside the phone - charge counter, voltage and temperature - and works out the battery's current full capacity in mAh. Compared with the factory capacity, that gives you battery health as a percentage, so you can see how much wear the battery has picked up. No root required.

WHAT YOU GET

• Battery health in percent, with a plain verdict on the wear
• Charge level, temperature, voltage and estimated full capacity in mAh
• Capacity history with a trend chart (PRO)
• Live power draw in mA, refreshed every second (PRO)
• The context that explains the draw: refresh rate, screen brightness, network type and signal, thermal state and memory use (PRO)
• PBH Pulse home-screen widget with a power trace over 60 seconds, 24 hours or 7 days (PRO)

FREE AND PRO

The free version measures your battery five times, so you can check the readings make sense on your phone before paying anything. PRO is a single purchase that lasts forever - no subscription, no ads.

ACCURACY

The result is an estimate from the fuel gauge, not a factory measurement, and typically lands within 3-5%. It is most accurate right after you unplug the charger at 100%. PBH takes the median of your recent measurements to cut down the noise from the sensor.

If your phone model is not in the built-in list, enter the battery's design capacity from its spec sheet once and the app handles the rest.

PRIVACY

Nothing leaves your phone. No account, no analytics, no ads, no tracking. Every measurement is stored on the device and nowhere else.
