IF your iPhone keeps running out of juice, a rogue app could be to blame.
Luckily, there’s an easy way to figure out what’s going wrong.
Apps can severely drain your iPhone’s battery life, so deleting the most power-hungry apps can significantly increase your life per charge.
Inside your smartphone are tiny computer chips that you use to operate the camera, watch a video, and everything else.
The harder the task (or the poorly designed app), the harder the processors have to work—and drain more juice from your battery.
Some tasks run in the background, e.g. B. tracking your location for Google Maps or checking Facebook for new notifications.
You don’t see these tasks, but they still drain your battery life.
Your iPhone has a built-in Apple tool that you can use to find out exactly which apps are draining your battery life.
Go to Settings > Battery and then wait for the page to load.
Next, tap on the “Last 10 days” option, which shows battery usage for various apps over the past week and a half.
If you scroll down, you’ll see the apps that used up the majority of your battery life in percentage form.
So, if an app has 20% next to it, it means that it has consumed one-fifth of the total battery life used in the last 10 days.
You can also toggle it to view the items listed by activity and organize them by battery usage.
So if you’ve spent very little time on an app but it’s at the top of your usage list, that means it’s a battery killer.
This section also breaks down the time the app has been running in the background.
Watch out for apps that consume a lot of battery and take up a lot of background usage time – they’re particularly bad for your battery life.
You can delete any apps that are causing problems, or you can turn on battery saver mode above.
Power saving mode temporarily reduces background activity on your iPhone until you can fully charge the handset.
Of course, it’s entirely possible that your iPhone’s maximum battery capacity has dropped.
In the battery section of your device you can see your maximum capacity.
This gives you the exact percentage of charge your iPhone battery is holding compared to when it was new.
For people with battery life issues, the percentage matters.
A battery is considered “worn out” when it is below 80%, which means it’s time to upgrade your battery.
You typically reach this point after 500 full charges — it takes most users less than two years.
If you’re still under warranty, you can request a free battery replacement from the Apple Store. Everyone else has to pay a fee.
It costs $79/£79 for a battery change, which is significantly cheaper than buying a brand new iPhone.
