iOS 8 - Close all apps with one tap?

Why have they not implemented a "close all apps" feature within iOS? I thought we would get something like this in iOS8 but nothing.

Thoughts?

It sure as hell IS necessary. Ugh people like you who think just because Apple hasn't incorporated something makes it unuseful.
Its not necessary because the system is designed to free up resources as and when it needs to. Many apps are often in a suspended state and not using any memory anyway.

iOS has had multi-tasking for a few years now and people still don't understand how it works, or think they can do a better job of managing their device's memory than the OS itself.

How can you make a personal attack with reference to someone's inner motives based on such a short statement?

On the other hand, your statement gives some evidence that you're the fanatic here since you make such an emotional response without basis.

because contrary to what most people believe closing all apps is bad for your battery life. when you close an app the phone uses more battery and resources next time you launch it, whereas if you leave it in the app switcher it's in a dormant state and when you launch it your phone won't work as hard to bring it up. So its ok to swipe up and close an app you wont be using for a while but if you have something that you keep going back to throughout the day its better to just keep it open.

This is why Apple probably didn't give that option.... I am not saying it's right or wrong so don't shoot the messenger, just giving you a possible reasoning for why its not included.

How do you know they are using up your battery life?

If they are suspended and not using any background services then battery impact will be minimal to none. All you are doing is removing them from memory and increasing the battery usage required to relaunch the app - if you are regularly killing apps you use on a regular basis this will be affecting your battery life even more.

The system will remove suspended apps from memory as and when it needs to - it will prioritise more popular apps over less used apps when purging. Trying to do a better job of memory management than the OS is pointless.

Why would you want to close them all and make your battery life worse?

I did not know this. That's why edited my post.

Useful if a buggy app stops working properly and you want to kill it and force a restart, or if you simply want to remove apps from the recently used list, but thats about it. It can occasionally be useful if you want to kill an app that is using a background service but if its causing you regular problems you would have better success in disabling background services for that app in Settings.

As a rule, I would consider any app that is using background services to an extent that they are having a noticeable impact on your device's performance to be buggy. But there's a limit to how much memory problems an app can cause because the system watchdog will kill apps that are using too much memory.

There is so much written about this, just google. Here is a few articles on the subject. First one is from an Apple ex-employee.

3. Stop quitting your apps in multitasking

Most people tell you that closing your apps will save your battery life because it keeps the apps from running in the background. However, this can actually make your battery life worse if you do it on a regular basis.

By closing the app, you take the app out of the phone's RAM, so when you open it again 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.

The truth is, apps in your multitasking menu are not running in the background at all: iOS freezes them where you last left the app. Unless you have enabled Background App Refresh, most of your apps are not allowed to run in the background.

No, the ability to close an app from the tray is to fix an app that has become unresponsive.

Unless the app expressly uses a Background Activity API of some kind (and you have not disabled this separately in settings per app, as you can do), there is no impact to battery life. Suspended Apps are not running.

RAM also doesn't care how many of these apps there are. App states are stored in a way that does clog up RAM, and thusly, not draining battery.

This is well known by developers. We are well aware that many users believe in lots of placebo effects, one of them being that quitting apps speeds up your phone or preserves battery.
