Lower Brightness Levels
The brighter your phone screen, the more battery being consumed — the facts are as simple as that. Lowering your brightness levels will require you to get used to using a less bright phone, which may be strange at first. But if you can deal with less light, it will pay off with a battery that simply stays charged for longer. Go to Settings > Display & Brightness > drag the brightness setting down lower.
Turn Off Background App Refresh
Background App Refresh is a setting that ensures your apps are constantly refreshing, even when you aren’t using them. The goal is for you to experience new content without waiting as soon as you tap on an app. But how necessary is this? If you can have a little patience and turn off this setting, you’ll be rewarded with a longer-lasting battery. Head to Settings > General > Background App Refresh to turn this setting off.
Don’t Use Wallpapers
Wallpapers is a very cool setting that allows you to customize your background image and choose from a variety of photos, emoji patterns, and other fun graphics. One rule of thumb though when it comes to your phone and graphics is that the latter can deplete battery power.
Turn Off Haptic Feedback
Haptic feedback is so satisfying because it provides actual sound when you’re typing on your phone’s keyboard. Is this necessary, though? No. And disabling it can help boost your battery power a bit. Turn this off by going to Settings > Sounds & Haptics > Keyboard Feedback. Turn off Haptic.
Location Services
You’ll need to have Location Services turned on if you’re using GPS, Bluetooth, or something like your Weather app. But, for the most part, you probably do not require this setting to be enabled at all times. Doing so can take a toll on your battery, as well. Go to Settings > Privacy > Location Services > and tap Never, Ask Next Time, or While Using the App to choose when and how you’ll allow your phone to access your location.
