Here is a little tutorial I have put together for the upcoming Motorola Moto X Style (Pure Edition). The new Moto X comes with a Q-HD display. Though a higher resolution might be nice it does use more battery as well. With this simple guide you can force the GPU to render the OS and everything in it, in 1080p instead of Q-HD. The display will still be Q-HD but everything on the phone, including the full Android OS, will be displayed in 1080p. This will increase S.O.T and battery life noticeably.

Prerequisites:

1) A rooted device running stock/stock based ROM.

Step 1:
Quote:

Install the Terminal Emulator app from the Play Store. Download from HERE

Step 2:
Quote:

Open the app and type the following:

Code:
su
Grant terminal Emulator super su access.

Step 3:
Quote:

Next type the following:

Code:
wm size 1080x1920

Step 4:
Quote:

After that, type:

Code:
wm density 420

Step 5:
Quote:

Finally to re-render all the un-changed drawables and pre-loaded system components type:

Code:
stop && start
Your phone will now reboot.

That's it! Now you can get some extra juice out of your new Moto X.

To Revert to Stock Settings:

Step 1:
Quote:

Code:
wm size reset

Step 2:
Quote:

Code:
wm density reset

Step 3:
Quote:

Code:
stop && start

Are there even any QHD videos or games available? What would make use of the QHD screen?

My point exactly...If you go the the Google developer stats website you can see on 4.7% of apps on Google Play take advantage of QHD. Also almost 89% of youtube videos are max 1080p. Knowing this I put together this guide. So at least Q-HD won't drain my battery.

If this phone comes out as scheduled or somewhere near that and I buy one, I'm going to avoid any tweaks or hacks for a while but I appreciate your info. Thanks for posting it.

This might just end up being a big battery saver.

This could be awesome or a complete fail. I know with other phones I have tried this on some stock apps like camera completely stop working and a lot of the FYI isn't working. However I didn't do this exactly so it may have been the wrong ethod. I'm excited to hear results. ☺

Code:
su
wm size 1080x1920
wm density 420
stop && start
