Many iPhone users believe that when they close all their apps, the battery will last longer. In fact, it’s just the opposite.
There was a long time ago when it made sense to close apps that were running in the background of your iPhone. It made sense because you saved a bit of power and your iPhone felt a little faster. Fortunately, that time is over. But no longer need to do this, and that has not been necessary for a long time. However, I see people daily who time and again close all their apps on their iPhone … even the SMS application. Then they open it again 2 minutes later. Of course, they think that they save battery on it, but in fact it can be just the opposite in many cases.
Let iOS control your apps
The control system on your iPhone (also called iOS) over time has become more intelligent, and one thing it does really well is to control which apps can run in the background, thereby using your phone’s RAM. The myth is that when you close your apps on the phone, they are not in the background and use power. That is not the case in reality. The iOS keeps track of the apps running in the background and automatically shuts down apps after a short while if they are not needed or if RAM is to be released.
Once you have used an app and then you press the Home button, the app will automatically be suspended by the operating system and stop using the processor in your phone. It no longer swallows electricity. There are, of course, exceptions to this, such as music apps where you are actively listening to music. An app like it will first be suspended when not in use. But as a basic rule, you do not have to spend valuable time closing apps in the iOS system for you.
It can sometimes look as though you have many apps running in the background when you get the double click on the Home button. But one must remember that the multitasking window also shows apps that the operating system has long since shut down. Instead, it is now just a shortcut to the app, and not something that is actively running in the background.
The only time it makes sense to shut down an app is if the app freezes or behaves.
You save power by NOT closing apps
When you close an app on your iPhone, remove it from your phone’s RAM. Ie that when you need to use the app again, the phone has to use processing power to open the app again, thereby using more power. Instead, if the app was still suspended in the phone’s RAM, it could be active at a split second – and at the same time, your apps open much faster, win / win.
Determine which apps must run in the background
On your iPhone, you can help determine which apps can run in the background and thereby save power. Enter settings and select the “General” menu item. Then find “Update apps in the background” and press it. You now get a list of your apps. Those marked with a green are those your phone allows to run in the background. If you have some apps that you do not need background activities, then you can turn it off. For example, by not allowing Facebook to run in the background, one can save a lot of power.
