##. I always try to improve battery runtime but it is not easy. None-AOD supported devices before Galaxy S7or LG G5 like Galaxy S6 or LG G4, they doesn't have Low-Power-Display so battery might be used more fast then before not using AOD with apps such like this app. This App was made by Korean High School Student. My hobby is developing apps not my job.
Get the .apk installer of Always On Display 4.5_release1 at no cost and read users' reviews on Droid Informer. This setup package takes up 4 MB on disk and it works flawlessly on Android 4.4 and above. The app has been scanned for viruses and it has been found completely secure. Dev. LR is the developer of this application which can be found in the Tools category.
Always On Display was downloaded and set up by over 100K users and its latest stable update was on Sep 18, 2020. On Google Play, the app was rated 3.8 by its users. Take into account its terms of use since there are in-app purchases and ads.
The way users see it, this application features some important advantages, they are a nice UI and update notifications. In users’ view, you can notice such a disadvantage of Always On Display as a battery drain.
