# Why does Android background delivery stop?

Android background delivery is limited by deep-sleep battery optimisation, which suspends background tasks after a few hours.

Android background delivery is limited by **deep-sleep battery optimisation**, which suspends background tasks after a few hours.

Workarounds:

* Have users exempt the app via **unrestricted battery use** in Android settings.
* Use Android SDK 1.7.3 or later and make sure the user granted Health Connect's background-read permission. Periodic syncs then run in the background, but aren't guaranteed to run exactly on schedule.
