To resolve this issue, I have added an additional two entries in the system.prop to allow vold to use the uevent names based on the user configuration. Unfortunately, on different platforms, the name of the uevent may be different, but Android vold hardcodes the uevent name. vold catches the uevent for power supplier type changing events. In essence, these entries tell the Android battery service code to look for the information in the correct place. #ro.sys.fs.power_.temperature is not supported #ro.sys.fs.power_.health is not supported Step 3: Tap the word Bluetooth, not the switch next to it, to see a complete list of connected devices and their current battery levels.

Different platforms, however, may give you a different directory layout under /sys/class/power_supply/, but Android hardcodes the directory layout to /sys/class/power_supply/. In Linux, applications collect the battery status through sysfs, where the battery status is located in /sys/class/power_supply/. This document explains how to configure the android-x86 platform to support different type of batteries. To resolve this issue, we have developed an easier method of supporting different platforms and battery types. When running Android on the different hardware platforms, the battery status often shows up incorrectly. Discharge your phone fully until it turns itself off. But if your phone battery is causing you real problems, its worth taking the risk. Android battery service was developed with only one type of battery and power management in mind.
