Automatic On/Off in Realme Smartphone is similar to Scheduled Power On/Off in OnePlus’s OxygenOS. You can use this feature for various purposes. For example, you can schedule to switch off the phone at midnight and schedule to switch on it after some time to refresh your phone and kill any resource-draining apps. You can see the Automatic On/Off option under Additional Settings in the Settings menu of your Realme phone. Once you set the time, your phone will turn off and turn on automatically (restart) as per your settings. FYI, Realme recently upgraded Realme 3 Pro and Realme XT to Realme UI (Android 10). The update brings a new UI design and several new features to the device. Smart Sidebar, Dual earphone connection, Native dark mode, Private information protection, etc. are few examples of the update.
