Short answer
Battery savers on Xiaomi, Samsung and similar phones close apps in the background, which stops location and alerts. On the child's phone, give SAFE Child an unrestricted battery setting, turn on auto-start, lock it in Recents on Xiaomi, and remove it from sleeping apps on Samsung. The Settings and permissions screen in SAFE Child walks you through each step.

- 2Turn on Autostart.
- 3Battery saver: choose No restrictions.
- 4Open Recents, then long-press the SAFE Child card (or swipe it down) and tap the lock icon.

Frequently asked questions
How do I know if it worked?
Lock the child's phone for an hour, then check the last activity time in SAFE Parent. It should keep updating.
Do I have to repeat this after an update?
Sometimes. A big system update can reset battery settings, so check the Settings and permissions screen again.
Does this drain the battery?
Battery use goes up slightly because the app is allowed to work. Turn on the low-battery alert to know before the phone dies.
