Rate this thread to express how you deem the speed at which the Samsung Galaxy S8's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

It is because of the android apps that is running in background. It keeps running if you are connected to the internet. If you checked which cause battery drains you will come to know that majority of apps are consuming too much power. It is better to install those apps which requires less space and don't updates frequently. Gaming Apps, Time management Apps, Fitness Apps, News Apps are updated almost everyday. So it is good to uninstall it if you are not using it.
I have seen many people who install so many apps but never used any which is not only uses the spaces but also consume the battery power.
