Batteries have a limited life. Every time you charge your device, the battery drains, reducing its overall (design) capacity.
Now, you can increase your phone’s battery life, spend less time with your Android device connected to a battery charger, and make more use of your phone’s life without constantly worrying about battery running low.
Use Battery Guru to find the fastest charger and USB cable for your device. Measure the load current (in mA) to find out! The app will show you the maximum current that has been reached while charging.


– A section dedicated to battery statistics, including charge / discharge ratio and estimated time of full charge / discharge.
Displays battery information: battery voltage, temperature, capacity, status, battery charger history …
The section also provides information about the app stats and the device’s deep sleep and wake time.

– Shipping records are also part of the information section, and this will tell you how much you care about the device’s battery if your charge is healthy or not. Shipping logs also contains advanced information to show you the shipment history of the last 3 months.

🛡️ protection
– In the protection section, you can set reminders for battery temperature and charging limits. As we know, these are two unwanted factors that degrade our batteries. Use the suggested protectors to extend battery life and keep it in good condition.

💊 health
– The health section contains useful battery saving tips, and everything is well described and ‘readable’.

– The save section contains save modes, two of which are already managed and cannot be changed, while one of them remains customizable. Managed mode reads the current state of the device automatically.
