I think many of you know this way but stop knowing what you want to share, you don't know if you need it. I used an iPad and one day I went out to the street, left the computer at home and on that day suddenly I found the battery of the phone down to 92% although it was morning before I left to charge. After finding out, it is due to the feature of screen lighting when jumping the notification, and the most for me is Messenger and Telegram.
To turn this off, it is quite simple, you just need to go to Settings -> Notifications, then find the necessary application, such as Messenger. Here, you will see all three notification methods are turned on and to prevent application notifications as bright screens, you uncheck the Lock screen. It is done. Since I turned off the wake-up feature when there are notifications for frequently used applications, the battery of the device no longer falls too much when I don't use it anymore. Hope this trick is useful to you.
