How To Control Samsung Galaxy S4 Battery Drainage
Not Completing 24 hours a day with a single charge is something that comes to many phones with age. Assuming you find that your S4 is not holding its charge for as long as it used to, it is possible that there is a problem with your battery, but it is more likely that apps are to blame.
You can check which of the apps you have installed are responsible for draining your battery by opening up Settings.
Tap More followed by Battery and you will see a graph that illustrates how your battery has been draining, as well as details of which apps are the culprits.
If you spot apps here that you are not using any more, you can simply uninstall them, but it may also be an indication that you need to remember to manually terminate certain apps when you stop using them.
Just press and hold the home button to bring up your Recent Apps list and then swipe away any apps you don’t use.
Probably you’ll notice that there is an entry for Screen very near the top of the list, if not at the very top.
If you tap this you will be able to see just how long your screen has been on while your phone has been unplugged.
To help reduce the battery draw your screen has, tap the Display button and try adjusting the Brightness and Screen timeout settings to something a little bit lower.
Longer battery life can also be achieved by enabling Power Saving Mode.
Head to the My Device section of your Settings and you can switch on the feature that will limit processor speed, turn off haptic feedback and automatically adjust screen brightness.
It’s also a good idea to turn off any phone features you are not using — like Air View, NFC and so on.
Swipe down from the top of the screen and tap the button to the far right.
In the list of Quick Settings, disable any options you do not need by tapping them.
