How can I change the battery level (from 50% to 70% and not charging) on emulator in Windows OS? There are some guides, but all of them are for Ubuntu.
telnet from the command prompt, at least on XP and Vista. If you do not find this program on other Windows versions, you can perhaps install PuTTY.
Then, you telnet into the emulator the same way that you would on any other development OS:
telnet localhost 5554
where 5554 is the port number given in the title bar of your emulator window.
From there, it's how the rest of the instructions that you have read describe it. For example, to set the
power to 70%, execute the
power capacity 70 command in the telnet session. There are other
power subcommands outlined in the documentation.
