No, closing apps does not save battery life. When an app is closed, it is not using any resources, but it is still running in the background. This means that the app is still consuming some battery power, but it is not as much as if it were running actively.
Closing Android Apps Doesn't Increase Your Phone's Battery Life. It's natural to think that background apps constantly use up your phone's battery. However, those apps are not the cause of your battery drainage, and closing them frequently will not increase your phone's battery life.
Closing background apps would not save much of your data unless you restrict background data by tinkering the settings in your Android or iOS device. Some apps use data even when you don't open them, therefore, if you turn off background data, notifications will be stopped until you open the app.
You should only close an app in the quick-launch screen if it is "misbehaving" - not working right, or if it is using energy (as per Settings/Battery) and you don't need it at the present time. There are several reasons you should not close apps.
When you close the apps, you are taking the app from that suspended state and putting it into an inactive state. This makes it more laborious for the phone to re-open the app next time you use it. Closing the app will also drain the precious battery that you are trying to save.
You Don't Always Need to Close All Apps on Your iPhone
However, this isn't necessary. In fact, Apple doesn't recommend closing apps unless they're frozen or not responding properly.
The biggest battery drainers are social media apps, including Facebook, Instagram, LinkedIn, Snapchat, YouTube and WhatsApp. They are in the top 20, and all allow 11 features to run in the background. Android and Iphones will refresh background apps periodically by default. This uses your phone's battery and your data.
Right?! Wrong. In the last week or so, both Apple and Google have confirmed that closing your apps does absolutely nothing to improve your battery life. In fact, says Hiroshi Lockheimer, the VP of Engineering for Android, it might make things worse.
You should close an app only if it's unresponsive.
On an iPhone, you only need to force close apps when they start misbehaving. iOS on its own is efficient in handling apps when left unused.
That perception, however, has been refuted, and the fact is that you do not need to close apps on your Android phone or tablet frequently. In fact, closing apps on your Android device can actually slow it down instead of improving its performance. Let's dissect why that's the case.
While background apps may not use your phone's resources on their own, Android phones and iPhones will refresh background apps periodically by default. This uses your phone's battery and your data.
There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi‑Fi. Dim the screen or turn on Auto-Brightness to extend battery life. To dim, open Control Center and drag the Brightness slider to the bottom.
Yes, indeed, those apps just keep running in the background and consume a lot of the power and other resources on the phone. While this fact may give the benefit of a quick start when you want to go back to them again, ultimately, they do slow down the phone.
There are too many apps running in the background. The screen is too bright. The screen is staying on too long before going to sleep. The phone doesn't have service.
It's not harmful other than the phone will actually use a little more battery power because once you have force close an app, it has to relaunch all over again when you use it again, whereas if you don't close an app and leave it a suspended state, it doesn't use as much power to wake it up from the suspended state.
What happens when you close Android apps? Closing apps on Android means shutting them down, and it isn't the same as permanently uninstalling them. Instead, app closing ends all current foreground processes. These processes are app activities that you can see.
If your phone's battery is draining faster than usual, it either means you're using a lot of energy or your phone is not using energy efficiently. This could mean you're overworking your phone by running too many applications, or something is physically wrong with the phone battery itself.
If the onset of your battery drain is sudden, it may be that an app updated or your phone installed a patch. The newer version could contain features that are more resource intensive, or has a bug which runs your battery dry. Check to see if any apps have updated recently.
