Tutorial: Turning off power saving on Android phones

In last couple of years, Android phone manufacturers have been concentrating improving the battery life of their phones. In consequence most new phones limit 3rd party apps’ access to the internal GPS when the app runs in background. Some phones will even stop applications from running in the background.

The intent is good, but all this has effect on apps like RaceChrono that collect data – even when the display is turned off and the app has gone to background.

Most phones have settings to turn off the power saving measures. Here’s the list of preferred settings for different phones, to allow recording in the background. Probably not all the settings are needed, but this list will give you a good starting point.

Please contact RaceChrono support if something is incorrect, or you have something to add.
