I never want my Android tablet to go to sleep, can I prevent sleep mode?

Depending on your tablet, you may have the option to set the screen timeout to "never" under Settings > Display > Sleep.

If you do not have this option, you can enable Settings > Developer options > Stay awake. This will keep your tablet awake while it is charging. This could be useful if your tablet does not support the "never" screen timeout.

Note: If you don't see Developer options in Settings, you may find them and Stay awake in one of these places:

  • You may first need to unlock developer options, as described here.
  • Simply search for Stay awake in Settings.
  • Settings > About > Build number. Developer options should appear after tapping the build number several times.
  • Settings > System > Advanced > Developer options
  • Settings > About > Android version > Kernel version

(Rowan) Note: Developer options are not always under Build number; they can be in other places such as Kernel version. The developers apparently try to hide them in various locations and I know this because I myself have found them in different locations on different devices.

There is a stay awake option while charging. For the older Android Froyo 2.2, it can be found under:

Settings > Applications > Development > Stay awake

"Screen will never sleep while charging."

The same option is still present up to the current 8.1 version, but you first have to unlock developer options.


You can probably prevent you tablet from sleeping using an automation app like Tasker (paid) or Automate (free).

Here’s a automation “flow” for Automate to keep the screen and CPU awake, but you can easily modify it to only keep the CPU awake: http://llamalab.com/automate/community/flows/374


I use the app Caffeine, and it works very good. It's free, and highly helpful. It's very small also (few kb).
