Touchwiz battery usage

[mark7914]

I've had to have the battery in my S8 replaced as it wasn't holding charge. When new it would last for two days on a single charge, before replacement it was down to perhaps 8 hours even when doing almost nothing.

What I have noticed before and since - using an app called AccuBattery - is that something called TouchWiz is the second biggest consumer of power.

Apparently that's an integral part of the operating system concerned with keyboard/screen input.

Everything else in the "Discharging" list makes sense except perhaps for this.

This is an S8 with the same OS and firmware as when new (Android 7) using a package blocker to keep it that way and prevent the phone from detecting updates so the battery drain doesn't have anything to do with OS updates.

In every way the phone is "like new" except for the fact that the battery life is simply not as good as when it was new even with the brand new battery.

Am I right in thinking that typing and scrolling will see this app use power but when the phone is idle it should not use any?

Is it normal for this to be such a big drain on the battery?

TouchWiz is your launcher - your home screen, your recents, your app drawer, your widgets. When the screen is on, it uses a lot of battery - because the screen is the largest consumer of battery. You should have the screen timeout set to about 30 seconds maximum. If you're not doing anything in 30 seconds, let the screen turn off. (If you need a longer time, say for reading a book or a long web page, an app like Tasker (not free, but worth it for what it can do) will let you set the timeout longer when certain apps are in the foreground, and revert back to 30 seconds when they're not.)

Thanks. Have reset that to 30 seconds (was 2 minutes).
