Sorry, Closing Your Apps Does NOT Help You Save Any Battery
It actually makes your phone slower and less coherent.

You're out with your friends and you realised your phone's battery is diminishing at an alarming rate. There isn't a charger or power bank in sight too!
What do you do?
Your first instinct would be to close all your apps to slow down the draining of your battery, right?
You couldn't be more wrong! Both Apple and Google have confirmed that closing your apps does absolutely nothing to improve your battery life.
Yup, seriously!
An Apple customer named Caleb emailed company chief executive Tim Cook to find out if the theory works. While Cook didn't write back, iOS chief Craig Federighi replied with a short and sweet response.
Not only does it not help, but your phone's going to do more work in the long run reloading those apps from scratch
By closing an app, you take the app out of the phone's RAM. While you think this may be what you want to do, it's not. When you open that same app again the next time you need it, your device has to load it back into memory all over again.
All of that loading and unloading puts more stress on your device than just leaving it alone. Plus, iOS closes apps automatically as it needs more memory, so you're doing something your device is already doing for you.

You see, those apps in your multitasking menu are actually not running in the background at all!
iOS actually freezes them where you last left the app so that it's ready to go if you go back. Unless you have Background Refresh enabled, your apps are not allowed to run in the background unless they are playing music, using location services or recording audio.
What about Android devices? Does the same concept apply?
Yup, the same concept applies. In fact, Hiroshi Lockheimer, the VP of Engineering for Android, says closing your apps might make things worse.
Lockheimer also explained that the Android system is designed to manage apps on its own and messing with it will cause more 'trash'. You can read the series of tweets here.
On both Android and iOS, algorithms run memory management, meaning that the system would automatically close apps that needs to be closed
These apps are typically apps that have been dormant for a while or are using more power or memory than they should. Both systems are very good at knowing when you’re going to need data, or want a refresh, or open an app again. You’re far better off letting the system work for you rather than forcing it to re-open and re-start everything every time.
If you’re into saving battery, there are lots of things you can do like using Low Power Mode in iOS, or enabling Doze on Android
You could also turn down screen brightness and turn off background refresh for apps like Skype, Instagram and Facebook. If you're desperate, putting your phone on Airplane mode would be the thing to do.
Just remember to stop swiping your apps out of view, because it’s not helping. If anything, it’s making it worse.
