Battery Hero: Health & Widgets

Battery widget, health monitor, per-app usage, screen time & drain rate

Track battery health, detailed screen time, drain rate and per-app battery usage with Battery Hero — the complete battery tracker and health monitor for Android.

Ever wonder which apps are eating your battery? Battery Hero shows you how much battery each app uses in the foreground, how fast it's draining, and how it's holding up over time.

🏠 HOME SCREEN BATTERY WIDGETS
Add a battery widget to your home screen in three styles — classic, minimal, and circular. It shows battery percentage, charging status, time to full, and time remaining at a glance — without opening the app.

📱 PER-APP BATTERY USAGE
See how much battery each app uses in the foreground. Per-app usage is estimated from current draw and app foreground time, helping you identify the biggest power-hungry apps.

⏱️ SCREEN TIME TRACKER
See your daily screen-on time across the past week. Tap any day to break it down hour by hour and see which apps kept your screen on the longest.

⚡ BATTERY DRAIN RATE
See how fast your battery is draining in real time. Measure your drain rate and view an estimate of how long it will last.

🪫 USAGE SINCE LAST CHARGE
See exactly how much battery you've used since you unplugged — power drained, screen-on time and screen-off time, plus the level you last charged to. Know whether apps or standby are draining your phone.

📊 REAL-TIME BATTERY MONITOR
Track battery voltage, temperature, current, and charge level in real time. See estimated time remaining and time to full when charging. Watch live stats update as you use your phone.
