Check Battery Usage Of iOS Apps

Last updated: September 16, 2014 at 8:26 am

Do you want to know which app consumes the most battery life?

How about a simple technique that will help you see a list of iOS apps quickly draining the battery life out of your iPhone, iPad, or iPod Touch?

And what if you could use this information to make your fully charged battery life last a little longer?

Apple demoed the key iOS 8 features on stage at WWDC, and one of the most simple yet handy addition was the…

Ability to Check Battery Usage Without Third-Party Apps

In earlier iOS versions, you have to download paid or free third-party apps from the App Store to deeply check the current battery life. They were good, but we always questioned their accuracy.

Jailbroken users could download apps like “Battery Life” that will show the battery’s charging state, cycles, temperature and even the capacity of your iOS battery. Note: If your device has a capacity of less than 75%, it is time to replace the batteries through Apple’s battery replacement program.

Now, all these details are useful, but the one solution that will really help you find out which apps consumes the most battery life is available right within your iOS 8 device.

Every iPhone, iPad, or iPod Touch running iOS 8 have access to this “Battery Usage” option wherein you can find out the apps (and even games) that are using the most or least of the battery life.

Here is an example:

As you can see, Safari consumed 21% of the battery life while WhatsApp Messenger used 1% of the entire battery life. Just swiping the home and lock screen took away 13% of the juice.

iOS 8 Battery Usage: How to Access This Feature

Make sure your iPhone 6, 5s, 5c, 5, 4s, iPad 2 and over, or iPod Touch 5G has the latest iOS 8 firmware installed. After that is confirmed, head over to the Settings.

From Settings, go to Usage. Here you will find the Battery Usage option.

You can either select “Last 24 hours” or “Last 4 Days” to check battery consumption of each of the app.

How does this information save you from a poor battery life?

It’s simple. Once you have found out the app that is eating the most battery life out of your device, you can do the following:

  • Stop using that particular app.
  • Find a replacement for that app.

For example, as Safari browser is using 21% of the entire battery life, we decided to switch to Google Chrome app. Did we notice a significant battery difference? Too early to tell, but this is how we use the data gathered from the Battery Usage option.

Another way is to minimize the usage of the battery-sucking apps, or close them if they are running in the background.

Note that, however, we wish Apple added a “reset” option or forced everything to be set back to zero. So that whenever the battery is fully charged, we can accurately analyze the data.

For now, such an option does that not exist. The simple (yet useful) Battery Usage should come in handy in desperate times.
