How to save your iphone battery.

Most of us take our trusty iPhone with us wherever we go. And if you commute long distances or are always on the go, you need your phone to last the distance.

Battery power plays a big part in the performance and popularity of mobile phones; so here are some tips on how you can save your iPhone battery to get the most out of your Apple device:


  • Adjust your screen brightness.

    You can prolong your battery life by adjusting screen brightness. Swipe up from the bottom of the display to open the Control Centre, then drag the brightness slider as far left as possible.
  • Turn off ‘push’ mail and notifications.

    You can choose to get emails manually by going to Settings > Mail > Contacts > Calendars > Fetch New Data.

    And if an app frequently wakes your display with notifications, you can turn these off in Settings/Notifications. Just tap the specific app and set Allow Notifications to Off.
  • Auto-lock your phone.

    While the screen of your iPhone is on, you're consuming power. If you want to get the maximum battery life from your iPhone, set the Auto-lock to one minute in Settings > General > Auto-Lock.

    Another tip is to press the Sleep/Wake button at the top of your iPhone as soon as you've finished using it.
  • Disable Bluetooth.

    Bluetooth is considered to be a battery-drainer. If you're not using it to connect to a speaker, headphones, or other accessory, or to use the Continuity features in iOS 8, then switch it off by going to General > Bluetooth.
  • Stop your iPhone vibrating.

    When your phone vibrates it drains the battery massively. Simply go to Settings/Sounds and turn off both of the vibrate options.
  • Turn down the volume.

    The volume setting on your iPhone will affect its battery life too. If you’re playing music or other audio from your phone, turn it down using the volume buttons. If you really need to save some battery life, you could switch to headphones, which don't need as much power as the iPhone's internal speakers.

    The music equaliser also takes up a surprising amount of power so go to Settings > Music and make sure EQ is turned to Off.
  • Disable app updates.

    Before iOS 7, if you switched between apps, the old app would be frozen. Now, you can see all the latest app updates while you’re doing something else which can burn through processing power and battery juice.

    Go to Settings > General > Background App Refresh to turn off Background App Refresh altogether; or you can choose which ones to turn off on an app-by-app basis.
  • Manage your app usage.

    iOS 9 was designed to be the most battery-efficient iOS ever. And it gives you more ways to improve iPhone battery life, because you can see exactly which apps are the biggest battery drainers. To view and manage your usage, go to Settings > General > Usage > Battery Usage.

    The arrival of iOS 9 also gives you a new battery-saving mode that Apple says should help your iPhone's battery life last much longer. We can’t wait to give it a try. In the meantime, there are plenty of portable chargers to help you out, like the Liquids Emergency Charger and the Premium Power Bank.
