Closing iPhone Apps & 5 Tips for Extending Your iPhone’s Battery Life

Learning how to save your iPhone’s battery life is a necessity for any traveler.  You don’t want to find yourself without a phone or internet connection when arriving in a new city via plane or bus.  You may also need to use it in an emergency situation.

Although you may not always have cell reception in a foreign country, it’s still a good idea to have your phone nearby.  You can use it as a flashlight, internet browser or as entertainment to watch movies and play games.

In other instances, such as at music festivals, you may want to have your phone last all day on a single charge.  (See Coachella survival guide for more music festival tips and tricks)

There are four ways to save your iPhone’s battery life: close background applications, turn off bluetooth, turn off Wi-Fi, reduce screen brightness and turn off cellular data.

How to close iPhone apps

Note: Refer to this tutorial for closing apps in iOS7

Many people are unaware that they have multiple applications running in the background on their iPhone.  Every time you open an application (such as Instagram, Safari or iTunes) it stays open until you close it or completely shut down your phone.  And every open app uses a little bit of processing power, which in turn uses your battery life.

Luckily, closing your apps is very easy!  **Note: If you have iOS7, please refer to this tutorial for closing apps **

  1. Quickly double tap the home button to open the multi-task bar.  You will see multi-task bar, which displays all of your open apps, along the bottom edge of the screen.

  2. Press and hold one of the app icons for a second or two.  You will notice the icons start to wiggle and a red minus symbol will appear on the top left of each icon.
  3. Press and hold an icon to display the close option

How to turn off Bluetooth and Wi-Fi

When you’re Bluetooth is turned on, your phone will constantly search for a device to pair with.  When your Wi-Fi is turned on, your phone will constantly look for a wireless signal to connect to.  All of this searching takes a lot of energy and drains your battery.

To turn off Bluetooth, go to Settings >> Bluetooth >> Select Off

To turn off Wireless, go to Settings >> Wi-Fi >> Select Off

How to dim iPhone screen brightness

Your screen is composed of thousands of little lights (326 per inch to be exact), and as we all know, lights require power to function.  Dimming your iPhone’s screen can save a significant amount of battery life.

To turn down your screen brightness, go to Settings >> Brightness & Wallpaper >> Slide to Reduce Brightness.  Also, make sure Auto-Brightness is turned on.  This feature will automatically dim your screen when you enter a dark room.

How to turn off celular data on Iphone

If you don’t need to use data (used for web browsing, sending picture messages etc.) you can turn off your cellular data to save your battery.  I often do this when I absolutely need to preserve my battery life.

To turn off cellular data and LTE 4G go to, Settings >> General >> Cellular Data >> Select Cellular Data Off


Armed with these tips, you should be able to preserve your iPhone’s battery life when necessary.  If you can’t live without Bluetooth, Wi-Fi, or cellular data, then you should consider purchasing a Mophie Juice Pack.  This nifty case also acts as an external battery and adds 8 hours of talk time to your phone’s battery life.

    Hate to spoil your breakthrough but I’m afraid it’s only 4 tips
    Closing down your background apps only wastes your time and doesn’t effect your battery.
    Closing down background apps may boost performance speed but not battery
    Other tips were great btw though!
