Charge current - allows you to set custom charging current. While this actually limits the current input, it effectively decreases or increases the available current transferred to the battery. This is useful in multiple ways:
- Slower, but more effective charging. Your battery will last longer.
- Faster charging when connected to USB. For example, USB charging is limited to 500mA, but newer PCs allow drawing up to 800mA or even more. This can be configured via the setting.
- Manual override of non-standard charger allowing to draw more than 500mA.
Magnetic sensor calibration - lets you delete previous calibration information. This is useful to recalibrate the compass (when it's inaccurate). Just tap the item & then open any compass up to recalibrate your sensor.
