Battery Doctor, Phone Booster

Battery Doctor, Phone Booster protects battery health, displays battery usage information, and measures battery capacity (mAh) based on science.

❤ Battery Saver

Batteries have a limited lifespan. Every time you charge your device, it wears out the battery, lowering its total capacity. Scientific research shows that battery lifespan can be extended up to 200%, when you charge your device to only 80%.

- Use our charge alarm to prolong your battery lifespan.
- Discover how much battery wear was endured during your charge session.

📊 BATTERY USE

Battery Doctor, Phone Booster measures the actual battery usage using information from the battery charge controller. Battery usage per app is determined by combining these measurements with information on which app is in the foreground. Android calculates battery usage using pre-baked profiles that device manufacturers provide, like how much power the CPU uses. In practice however, these numbers tend to be highly inaccurate.

- Monitor how much battery your device is using
- Know how long you can use your device when it’s active or in standby mode
- Find out how much power each app uses.
- Check how often your device gets woken up from deep sleep.
