What is the problem?

Most smartphones these days have long-living batteries, but who doesn't want their phone to last for just an hour more? While using an app, you maybe not necessarily need your display. Up to 20% of your battery power is consumed by the display. So, why not turn off all the pixels on it? Plus, this app can help prevent burn-in caused by statically displayed images and text.

Here is the solution!

FakeStandby is an Android app to turn off your screen while keeping apps running. This includes foreground jobs, which means you can keep

  • listening to music on YouTube
  • staying online in various text messengers
  • running your favorite game
  • listening to podcasts

all with your screen turned off!

Some more use cases

A user has reported to use the app to keep the GPS tracking in a buggy navigation app running, whlie the phone is in the pocket. Another user wrote me he uses it while driving to have a video call in only one direction where the calling person could see them, but the driver is not distracted.

How does it work?

This app displays an overlay over the foreground app using Android's accessibility services. All it renders on the overlay is a black canvas, effectively turning your pixels off. The apps you're using won't notice this, because technically your phone is turned on.


Some smartphones have LCD displays with background lighting that only turns off when you actually press the power button to lock your phone. The concept of this app works better with OLED or AMOLED displays, where "turning pixels black" is identical to "turning pixels off". You should not except huge power saving effects on any device, especially on devices with LCD displays.
