Going to use 1080p on this device for a few days topic

I'm going to downscale the device resolution to 1080p for a few days if the 2K screen really affects the battery that bad.. If you want to do this, download Resolution Changer from Google Play, and set the screen res to 1080x1920 480 dpi, apply and reboot (important to reboot, if not, the UI will be messed up)
Going to edit this in 3 days. Cheers!
