Battery life on the Galaxy S8 is actually quite good.
Especially if you opt for the larger plus variant.
But, if you find yourself needing to top off the device throughout the day, there are a few settings you can adjust to stretch out a single charge.
Glancing at your phone, as it sits on your desk, to check the time or view pending alerts is very convenient.
But, it's also a slow drain on the battery.
You can disable the always on display by going to settings, lock screen and security, always on display, or by toggling it in the quick settings menu.
You can also change the Galaxy S8's screen resolution between HD plus, FHD plus, and WQHD plus.
You will see a small but noticeable boost in battery life by- Switching to a lower resolution.
Samsung makes it easy switch screen resolution on the fly by using either the power saving or performance mode toggles in the quick settings menu.
But of all, turning on power saving would increase the screen resolution to FHD plus Decrease screen brightness and activate a CPU speed limiter.
You can make it switch to HD+ for even more power savings.
Performance mode increases the screen brightness and ramps up resolution to WQHD+.
The Galaxy S8's auto brightness is sort of aggressive.
That tends to err on being too dim and then sometimes makes the screen too bright.
I often end up adjusting the brightness myself anyway.
So to save yourself from frustration and also some battery life in the process.
Turn off auto brightness.
Pull down the quick settings panel.
Tap the small arrow next to the brightness slider and toggle the auto adjust button to the opposition.
To conserve battery, Samsung's custom software would put unused apps to sleep.
When an app is sleeping, it won't run in the background and any push notification from the app- Will be paused.
The Galaxy S8 will automatically sleep inactive apps, but you can manually put apps to sleep as well.
Long press on an app icon until a settings pop up is shown.
Select sleep from the list.
Then tap OK.
