Here I have TCL 10 SE, and today I'm going to show you how to enable power saving mode on this device. So first, you have to open settings then go to the smart manager battery, and here you have normal saving mode. You can switch it here, and you can also access some settings of this mode here and the only option is the schedule, and you can just set it for you here, and you can also switch power saving mode here at the upper bar, and that's it, thanks for watching.
