How to check screen time on Android
So, how to check screen time on Android? From your device's home screen, pull down the Quick Settings panel, and tap on the battery icon that you'll see in the upper right corner. Once you do that, a Battery menu will show up, displaying detailed info on what's draining your battery. Most of the time, your Android's screen time will be among the top battery consumers, so you should be able to notice a Screen tab somewhere in there - tap on it when you spot it, and that's it: you'll see exactly how long the screen has been on. Note that this is the screen-on time since the last full charge - so it won't be accurate if you have the habit of charging your phone or tablet without waiting for the battery to get to 100%.
