These quick tips will help to make sure that you’ll get the most out of your iPhone or iPad’s battery.
Turn off Background Refresh
This setting enables apps to use the internet to refresh information when they are running in the background. Although this can save you time when you open up an app, it will cost you battery life. To change this setting go to Settings > General > Background App Refresh. You can choose to either turn it off for every app, or just for ones which you don’t use very often.
Turn off Location Services
This setting can drain a huge amount of your battery, as it allows apps to turn on your GPS and check your location whenever they want. Threats to privacy aside, this will use a lot of battery. Outside of a few apps which make specific use of your location, for example, Maps, most don’t really need to know where you are, so why waste the battery? To change this setting, go to Settings > Privacy > Location Services. From here you can choose to disable all by tapping the slider at the top, or scroll down to disable access on an app by app basis. At the bottom of this list you’ll also find System Services where there are more settings which you can modify. ‘Frequent Locations’ is a relatively new setting found here which delivers you location-based ads and drains your battery.
Having a notification pop up to tell you that you’ve missed a call is very handy, but some apps use this feature to advertise or, it seems, to just plain annoy you. Turning off notifications for apps which bombard you with notifications, or ones which don’t concern you, will save you plenty of battery life. To do this, navigate to Settings > Notification Center. From here you can click on individual apps and choose whether or not they appear in the Notification Center. Additionally you can also modify the appearance of certain notifications, making them bigger or smaller.
Keeping your device’s wifi on at all times will drain its battery quickly if you aren’t connected to a wifi network. This is because your phone will keep searching for an available wifi network until it finds one, so turning wifi off when you leave the house can help save your battery life. However, you should remember that accessing the internet over wifi uses less battery (and typically also less money) than your mobile network’s 3G or 4G connection, so where possible, always use wifi.
On Apple devices you can turn wifi on and off by swiping up from the bottom of your screen and clicking the wifi icon; if it is grey then it is deactivated.
Your smart device will be configured to automatically turn off its display after a certain length of inactivity. By making this amount of time shorter, you can save your battery life, and also make your device more secure.
On Apple devices, you can find this option under Settings > General > Auto-Lock.
The brighter your screen is, the more battery it uses. To help combat this you can activate a feature which automatically dims your device if you’re in a dark room (it’ll also save your retinas if you check your phone whilst in bed).
To change your screen brightness on Apple devices, swipe up from the bottom of your screen to access the Control Center. Auto-Brightness can be activated by navigating to Settings > Wallpapers & Brightness.
