Note: "icon" here referred to the settings entry icon at the upper right corner of certain apps
1. Lock Apps(@Security\Boost speed\"icon"),
2. App battery saver(@Security\Battery\"icon"),
3. Battery optimization(Settings\Privacy protection\Special permissions).
What are the differences between these 3 settings? Why would a phone have 3 settings with seemingly similar purpose? I believe there’s a different job for each, but i don’t know how they differ. A explaination/clarification would be much appreciated. Thanks in advance
