Hi @SuzieSoo Are you using the optimisation tool within Device care? You have a few options in Power Mode, High performance will use up more Battery Life so think optimised is a good choice or you could consider Medium power Saving. Best to only have Wi-fi and Bluetooth on when you need them (though the Covid-19 apps require bluetooth ) You can put some apps to sleep so they are not always running in the background and may wish to look at sync settings for some apps.
