Batteries have a limited lifespan, every time you charge your device it drains the battery, reducing its total (design) capacity.
Now you can reduce wear and tear, spend less time with your device connected to the charger, and get more out of your mobile phone’s life without constant worry about low battery power.
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 reached during charging.
