Battery Guru: Battery Health v2.4.9.2 build 703 [Expanded] [Mod Extra]
Requirements: 7.0+
Overview: Battery Guru displays battery usage information, measures battery capacity (mAh), show estimates, and helps you change your charging habits with useful tips to prolong battery life and increase its lifespan.
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.
Battery Health and Capacity
Your phone shows a percentage. Battery Guru shows you whether your 4000 mAh battery still holds 4000 mAh or has quietly lost 20% of its capacity over time.
– Actual battery capacity in mAh compared to original design capacity
– Battery health percentage and capacity loss tracked over time
– Battery wear analyzed per charging cycle
– Charging cycle count from system data or calculated from your session history
– Maximum temperature recorded during each charging session
Charging Speed and Current
Not all chargers deliver what they promise. Battery Guru measures the real current flowing into your battery so you can compare chargers and cables by actual performance.
– Live charging current in mA and power in Watts
– Voltage readings in mV
– Estimated time to full charge with screen on and screen off shown separately
– Complete charging history with start time, end time and capacity per session
– Compare chargers and cables by their real measured output
Battery Drain and Usage
When your battery drains faster than expected, Battery Guru shows you exactly where the charge is going.
– Screen on time, screen off time, awake time and deep sleep time
– Battery usage by app running in the foreground
– Wakelock monitor to identify apps and system processes keeping your device awake in the background
– Alerts when abnormal battery drain is detected
– Discharge rate and usage pattern history over time
Temperature Monitoring
Heat is the leading cause of permanent battery damage. Battery Guru tracks temperature continuously and alerts you before harm is done.
– Real-time battery temperature with 24-hour history graph
– Custom high and low temperature alarm thresholds
– Minimum, maximum and average temperature per session
Alarms and Notifications
– Full charge alarm so you unplug at the right time and avoid overcharging
– Low battery alarm before you run out
– High battery drain warning when something unexpected is consuming power
– Temperature alarm for both overheating and cold conditions
– Status bar notification with customizable icon showing percentage, temperature or both
– Do Not Disturb schedule so alarms respect your sleep hours
