Phone Still Awake
You must have wondered many times as why your phone screen turns off so quickly and goes to sleep. It is due to the fact that most of your battery is spent lighting up your screen, and the longer your screen is left on, the quicker your battery will deplete.
The following few steps will help you to find out how to change the length of time your phone to stay awake.
1. Open your Apps list and find Settings.
2. Tap on it to continue.
3. Scroll down the list until you find Display, gestures & buttons.
4. Press it to view the display settings for your HTC One phone.
5. Find and tap on the Screen timeout option.
6. You can choose from a number of different time settings. Pick either one or two minutes as anything higher will make your battery run down much quicker.
7. If you’re feeling adventurous you can set it higher.
8. If you’re not touching the phone screen for longer than two minutes it’s usually because the phone isn’t in use so set the time setting accordingly.
