Turn off Adaptive Battery optimization and Auto optimization: While in the Background usage limits option, tap the three-dot icon in the top-right corner and select Adaptive battery. If you think your phone is delivering good battery life, as most high-end smartphones do, you can turn off the Adaptive battery option. This way, the apps will behave predictably instead of intelligently using AI. Inside Device Care, you will also see the Auto optimization option. This feature periodically restarts your device and force-closes background apps on a schedule to keep things running smoothly. However, instead of keeping things on the smoother side, it interrupts anything you had running and resets apps you wanted to stay open. When you turn the Auto optimization feature off, your phone won’t be quietly rebooting itself or closing apps while you aren’t looking.

Say goodbye to RAM Plus: Plus. Samsung has a feature, RAM Plus, enabled by default, that acts as virtual memory. To do that, head to Settings -> Device Care -> Memory -> RAM Plus. Here, when you turn off RAM Plus, your device will prompt you to restart. Proceed, and RAM Plus will be turned off.
