A Device reports normally for a while, then goes quiet for most of a day, then reappears as if nothing had happened. Nobody touched it, nothing failed, and it was often sitting on a charger the whole time.
That is almost always the manufacturer's battery layer suspending the Applivery agent to save power. Many Android manufacturers add their own power management on top of Android's, and it is far more aggressive: it decides which background Apps get suspended, and the agent is treated like any other App.
Ruling out Android's own power saving
Android has its own mechanism, Doze, and it is the obvious suspect. It is usually the wrong one.
Doze does not apply while the Device is charging. So if the Device was plugged in and still stopped reporting, Android's own power saving is ruled out and the cause is the manufacturer's layer. This single check separates the two.
Excluding the agent from battery optimization
The fix is to tell the Device to leave the agent alone. The exact route depends on the manufacturer and on the version of its Android skin, so treat these as a starting point rather than exact steps.
Manufacturer | Route |
|---|---|
Redmi / Xiaomi | Settings → Apps → Manage apps → select the App → turn on Autostart and set battery saver to No restrictions. |
OPPO | Settings → Battery → select the App → allow background activity with no restrictions. |
Samsung | Settings → Battery → Background usage limits → check the App is not listed under "Sleeping apps" or "Deep sleeping apps". |
Exclusions can be reverted by a firmware update. Build them into your periodic checks on affected models rather than treating them as a one-off fix.
For per-brand detail, dontkillmyapp.com is a useful community reference. It is not official documentation, so use it alongside the manufacturer's own settings rather than instead of them.
Devices marked as inactive
A Device is marked as inactive after 5 days without reporting, so a suspended agent is one of the ways a perfectly healthy Device ends up flagged. See Device States for what the status fields actually mean.
If the exclusion is in place and the Device still goes quiet, contact Applivery Support: we can review the agent activity on that Device and confirm whether it is still being suspended.
