HOW TO ENABLE SYSTEM UI TUNER IN YOUR ANDROID.

To enable the System UI Tuner on your device. The primary reason I do this is to get a numeric representation of battery life remaining on my device on the status bar. To enable this functionality, you will first need to activate the hidden settings menu by following these steps:

1. Swipe down on your screen to show notifications.

2. Swipe down again to show device settings.
3. Press and hold the small cog/gear icon on the top right hand side of the screen and then release it.
4. Enable the System UI Tuner menu.
5. Go to your device settings and scroll to the bottom and click System UI Tuner.
6. Click Show embedded battery percentage and you are done.

There are many additional options that you can play around with in this newly activated menu, but showing battery percentage via number is my favorite.
