Battery optimizers allow mobile devices to extend their batteries but at the expense of performance, notifications and even shutting down background services on your child's device. Boomerang in Child Mode needs to run as a background service and can get turned off by these very aggressive battery optimizers.
Similarly to Huawei and Xiaomi, Meizu take a very aggressive approach to background process optimizations. Meizu is not as popular in our user base so we do not come across them as often. Here are a few things to try if your child has a Meizu device.
Adjust your settings:
- Device Settings > Advanced Settings > Battery manager > Power plan set to Performance
- Device Settings > Advanced Settings > Battery Manager > Protected apps – check your app as Protected
- Enable Device Settings > Apps > your app > Battery > Power-intensive prompt and Keep running after screen off
