Can't change battery configuration in Android Emulator

I'm trying to change in my emulator the battery status as capacity and ac status but isn't working.

I made the whole steps:

1) Connected to the emulator via telnet;
2) Tried to use the commands such power ac off and power capacity 70
3) Every time I checked the power display, the same configuration appears and no change I input is save, and the emulator always show the battery with a "!".

FR I saw this link Change emulator battery level in Windows, tried it and nothing resolved.

Follow my data about the battery:

power display
AC: online
status: Not charging
health: Dead
present: false
capacity: 0

Thank you!

Solution

It seems like your emulator device has battery option turned off.

You can change AVD battery configuration through:

Open AVD configuration file:

Default location for Linux/MAC

~/.android/avd/<AVD name>.avd/config.ini

Default location for Windows XP

C:\Documents and Settings\<user>\.android\avd\<AVD name>.avd\config.ini

Default location for Windows Vista and later

C:\Users\<user>\.android\avd\<AVD name>.avd\config.ini

Change the line:
```
hw.battery=no
```
to
```
hw.battery=yes
```
