Most Android devices and ROMs these days include some kind of support for displaying the battery percentage in the status bar, but not stock Android. For whatever reason, Google has neglected this very basic feature – until now. Android 4.4 on the Nexus 5 includes a battery percentage display option, but it's pretty buried and far from an ideal implementation.

percent-49 percent-39 percent-28

You can enable this hidden feature (without root) on the Nexus 5 using the following ADB shell command:

adb shell content insert --uri content://settings/system --bind name:s:status_bar_show_battery_percent --bind value:i:1

adb reboot

After the device reboots, you'll have a battery percentage indicator, but it's inside the battery icon and the digits are white. Yes, that means you can only see the number when the gauge gets fairly low – in the mid-40s or so. If the ADB thing isn't up your alley, an XDA member has thrown together an app that can do the same thing, and just like the above, no root is required.

This really feels like an unfinished feature. The fact that there isn't even a toggle in the developer options bears that out. Still, the code is there. I can only hope Google makes this a real option with a future OTA.
