iPad: app stops when screen is locked Basically I have a problem with apps stopping when the screen is locked. I have first encountered this issue when I started using Strava. 

I would normally start recording on Strava, lock the screen and put the iPad into my backpack, after I finish the ride, I would unlock the screen just to find out that the app is not running.

I initially though that this is Strava specific issue, but I have since tried Endomondo and it exhibits exactly the same behavior.

Few details:


If I start the recording, then lock the screen, then unlock it within the short period of time (~ 1 minute or less) - the app is still running. Which means it does not stop immediately after the screen lock
If I don't lock the screen, but just put the iPad into my backpack, the screen locks automatically in 5 minutes. In this case, no matter how long I ride, the app will keep running and will be still active when I unlock the screen. This is a workaround but not prefered solution


I would like to know why does iPad stop apps after the screen lock and how do I change that behavior.

I am using iPad mini and iOS 8.2

UPDATE:

based on the comments and answers from other users, few more details:


Location Services are enabled for these apps and set to "Always on"
Background refresh is enabled in the system and for these apps
The worst, but working solution will be to set screen locking to 30 seconds, so that it will go to sleep faster. Looks like apple does it on purpose.
