To set your Nexus 4 display so that it is always on whilst charging you need to get into the developer options. On Android 4.2.1 and higher this requires you to do the following process to get access to these options:
- Within Settings, select About Phone
- Now scroll down to the bottom and find the Build Number
- Tap the build number 7 times
After 7 taps the developer options become are available under the System section of Settings. Google have decided to hide this option on the Nexus devices as I guess it keeps some of the power options out of the hands of regular folk. I guess there is potential for not technical people to get confused by some of the options and set things they didn’t mean to.
To set the display to stay awake, tick the box next to Stay awake. With this set your screen stays on whilst plugged in.
Why Do This?
If you are developer you’d want your phone to stay unlocked whilst on charge as it makes testing software that much easier. If you listen to music in the car, then whatever track you are playing stays on screen. Also if you wish to use your Nexus 4 as a bedside clock then it can be handy to have the display on all of the time.
Turn it off
If you want to turn the display off, then the on / off button will turn the display off and continue to charge your phone. Alternatively you can uncheck the stay awake box in the developer options.
Any more ways to use the stay awake feature?
I’d be interested in hearing if you have any cunning ways to utilise the stay awake feature as I’m finding that it serves a purpose beyond what it is initially intended for.
