The PowerLED is the forgotten feature on a m5xx. BatLight makes this feature useful.
BatLight is a program that links the battery level to an LED action. With BatLight active you can see whether the battery is below a defined level or/and when the device is attached to a cradle/travel charger and whether it is charged or charging. Depending on your settings BatLight can set the PowerLED off, flash or on when the battery is charging, charged or/and low. BatLight only works with a m5xx device and OS 4.x. BatLight also calculates different statistics about the charging process and low level warnings. The statistics are separated in three different groups: general, charging and low level statistics.
