4. Close Out Your Apps
Once every day or two, it’s a good idea to close out your apps. In a perfect world, you would never have to do this and most Apple employees will never say you should. But the world of iPhones is not perfect – if it were, you wouldn’t be reading this article.
Don’t Apps Close When I Go Back To The Home Screen?
No, they don’t. They’re supposed to go into a suspended mode and stay loaded in memory so that when you reopen them, you pick up right where you left off. We don’t live in iPhone Utopia: It’s a fact that apps have bugs.
A lot of battery drain issues occur when an app is supposed to close, but doesn’t. Instead, the app crashes in the background and your iPhone battery beings to drain without you even knowing it.
A crashing app can also cause your iPhone to get hot. If that’s happening to you, check out my article called Why Does My iPhone Get Hot? to find out why and fix it for good.
How To Close Out Your Apps
Double-click the Home Button and you’ll see the iPhone App Switcher. The App Switcher allows you to see all the apps that are stored in the memory of your iPhone. To browse through the list, swipe left or right with your finger. I bet you’ll be surprised by how many apps are open!
To close an app, use your finger to swipe up on the app and push it off the top of the screen. Now you’ve really closed the app and it can’t drain your battery in the background. Closing out your apps never deletes data or causes any negative side-effects – it can only help you get better battery life.
How Do I Know If Apps Have Been Crashing On My iPhone? Everything Seems Fine!
If you’d like proof, go to Settings -> Privacy -> Diagnostics & Usage -> Diagnostic & Usage Data. It’s not necessarily a bad thing if an app is listed here, but if you see a lot of entries for the same app or any apps listed under LatestCrash, you might have a problem with that app.
The App Closing Controversy
Recently, I’ve seen articles that say closing out your apps is actually harmful to iPhone battery life. My article called Is Closing iPhone Apps A Bad Idea? No, And Here’s Why. explains both sides of the story, and why closing out your apps really is a good idea when you look at the big picture.
5. Notifications: Only Use The Ones You Need
We’ve all seen the question before when we open an app for the first time: “App Would Like To Send You Push Notifications”, and we choose OK or Don’t Allow. Few people realize how important it is to be careful about which apps you say OK to.
When you allow an app to send you Push Notifications, you’re giving that app permission to keep running in the background so that if something happens that you care about (like receiving a text message or your favorite team winning a game), that app can send you an alert to let you know.
Notifications are good, but they do drain battery life. We need to be notified when we receive text messages, but it’s important for us to choose which other apps are allowed to send us notifications.
How To Fix Notifications
Go to Settings -> Notifications and you’ll see a list of all your apps. Underneath the name of each app, you’ll see either Off or the kind of notifications that app is allowed to send you: Badges, Sounds, or Banners. Ignore the apps that say Off and take a look through the list. As you go, ask yourself this question: “Do I need to receive alerts from this app when it’s not open?”
If the answer is yes, leave everything as it is. It’s absolutely fine to allow some apps to notify you. If the answer is no, it’s a good idea to turn off notifications for that app.
To turn off notifications, tap the name of the app and turn off the switch next to Allow Notifications. There are other options in here too, but they don’t affect your iPhone’s battery life. It only matters if notifications are off or on.
6. Turn Off Your Phone Once A Week (The Right Way)
It’s a simple tip but important nonetheless: Turning your iPhone off and back on again once a week can resolve hidden battery-life issues that accumulate with time. Apple would never tell you that because in iPhone Utopia, it wouldn’t.
In the real world, powering off your iPhone can help resolve issues with apps that have crashed or other, more technical problems that can occur when any computer has been on for a long time.
A word of warning: Don’t hold down the power button and the home button at the same time to shut down your iPhone. This is called a “hard reset”, and should only be used when absolutely necessary. It’s akin to powering off a desktop computer by pulling the plug out of the wall.
How To Turn Off Your iPhone (The Right Way)
To power off your iPhone, press and hold the power button until “slide to power off” appears. Swipe the circular power icon across the screen with your finger and wait as your iPhone shuts down. It’s normal for the process to take several seconds. Next, turn your iPhone back on by pressing and holding the power button until you see the Apple logo appear.
