Apple Reiterates: Force Quitting iOS Apps Doesn’t Help Battery Life

It does absolutely nothing except give me peace of mind for my compulsive brain.
These are the people that don't let facts get in the way of their beliefs. Just give up.
I remember Steve Jobs saying when quick switch/multi task was introduced in iOS that it wasn’t necessary for the user to quit apps to stop the battery draining etc.
Here’s a link which refers to what I mentioned above.

iTunes for windows was done out of necessity to get them to sell more iPods... a LOT more ipods than Apple ever would have if it kept it restricted to just OS X.
iMessages for Android would mean less of a reason to buy an iPhone. WON'T HAPPEN.
I tried an experiment. I closed all apps on my iPad Mini 4. Cleared the task bar. Charged that puppy to 100% overnight.
In the morning I opened Kindle and read off and on all morning (vegetable day
). At the end of 5 hours I was seeing 83%. Next day I did the same except (you knew this was coming ) I opened TWC TV then closed it. Kindle all morning long. At the end of 5 hours I was seeing 52%. I have tried this several times over the last week doing different things with the only difference being whether or not TWC TV was in the task manager. In every single case, my battery consumption was significantly higher with the TWC app in the task list.This tells me that the original comment was misleading and likely carefully worded politic speech.
YMMV. For me, this was as conclusive as I need. I generally do not empty the task list unless I see abnormal battery consumption. This action though, is not an uncommon occurrence.
ok, i can tackle a challenge
Apple's improved battery life can be a result for why u could be seeing this.. However,, it boggles the mind to even think 'how can u get "better battery" running apps in the background ?"
That's a new one on me.And something i'd rather not try and solve.... That's for you lot

Interesting! This is kind of the problem with abstracting stuff too much...the reality is the more like a real OS something is, the more it really does need basic tools, like a task manager or the like.
It occurs to me that maybe for these mobile OSes the program switcher could list CPU usage (and RAM usage that it won't give up)...that would take the guesswork out of things. If it's any thing other than 0, we'd know to manually quit it unless we have a specific need to keep it open.
FYI, I'm gonna ask Apple to make an Official statement that Force Quitting backgrounded apps does in-deed improve the Performance, sometimes SIGNIFICANTLY, of HIGH Performance apps running in the Foreground !
Too many people simply do NOT know that it does !
The problem is REAL, and Apple really needs to fix it ! ... i.e., lack of education.
For those of you who don't know, backgrounded apps do NOT use up processor cycles (& thus are NO drain on the battery), but they eat into your available memory ... as such, they cripple High Perf apps that require lots of available memory (i.e., DRAM).
Even the three Apple mobile devices with 3 GB of DRAM (i.e., 7+, 8+ and X) require this to perform at their best, with High Perf apps.
You'd be surprised how many people spend $1K or more for a new iPhone, yet don't know that it's simply a custom computer, and that the availability of DRAM for an app is crucial to it's Performance.
Apple really needs to step up to the plate & do a much better job of educating it's customers.
And don't get me started on How Badly Phil Schiller dropped the Ball with their Rollout of Wide Color ! ... I give him, and Apple, an F-- for that one !

Apple certainly needs to educate users better, given that people like you that claim to know what's going on seem to be stuck in the 80's, when one had to manually adjust the OS's management of memory. So maybe your request will actually be useful, even if it ends up in Apple saying exactly the contrary to what you expect.
Also, you sound like you might fall prey to scammers like those pumping "memory optimizer", "memory cleaner" apps you'll see around the web. Just remember: this is not the 80's anymore! And if someone mentions "High Perf apps", make sure that your wallet is firmly settled in your pocket and slowly back away.
Also, stop trying to low-level format your (rotating) hard disk!
Backgrounded apps are discarded when other/active apps demand the memory.
But please, tell Apple how you know more about their OS than they do.

Yeah, iOS dumps programs from RAM when more RAM is needed. (And obviously even on full OSes like Windows and MacOS they can dump them to virtual memory as needed...which is sort of a similar idea.)
The confusing thing here of course is that there's SOME kernal of truth to "closing" programs. Most stuff I figure is well behaved...I'm certainly not worried about programs from Apple (save for Safari, technically) or other companies I trust.
BUT it is possible for programs to stay open in the background for good, or potentially nefarious reasons. Netflix and Amazon Prime's programs for example can continue running to continue downloading data, which is great. (The TiVo program is excellent, but doesn't seem to be coded to allow running in the background for that purpose.)
And then programs can potentially do nefarious things-collect data while in the foreground or background. At least as of iOS 10 it was possible for web pages to keep collecting data in the background. (I HOPE Apple has gotten more aggressive about preventing that...obviously it's not something that's obvious/easy to understand why OS companies wouldn't think to worry about it at first!) At least as of iOS 10 we technically should all be force quitting Safari (or closing all open pages) when we're done with it, to prevent tracking.
Sooooooo MOSTLY there's zero reason to be manually managing it, but there can be badly coded programs that wind up running in the background for no good reason, or well coded programs that stay running in the background for bad reasons.
I'm still shocked that even on a 2GB iPad I'm sometimes witching to a program, switching directly back to the previous program, and STILL having it reload from scratch. 2GB right now still ain't bad, but I wish Apple would be several years ahead of where they are with how much RAM they stick in these things. The iPhone 5 should have had 2GB, the 6s probably ought to have had 4 by then, instead of being the first with 2 lol

Did this thread really need to be dug up from well over a year ago just to rehash the things that have already been brought up multiple times over the already existing 10 pages?
Actually, they can. If they play audio, or use background tasks, and so on, they will use up CPU.
No, not typically. iOS is quite aggressive about purging your background apps from memory.
It's not such a big issue now that these devices have much more RAM and the flash storage is much faster, but anyone else annoyed by how iOS takes a photo of a running program to try to make it look like it's responding faster than it is?
Like when you switch to a program, I'd rather just have some indication that it's loading, rather than staring at a JPEG that LOOKS like the program but isn't. Used to be an issue on older devices, where you'd get no feedback on when clicking the program would actually do anything, since you're not REALLY clicking the program until it's loaded.
Not such a big deal now, but even still you get weird things like I loaded settings and went "what?!?, my VPN is on?!? I thought I switched that off hours ago?!?" only to have it turn out that I was just staring at an IMAGE of the settings program showing incorrect info. Was confusing enough even knowing how this works, which most people wouldn't since it's never explained.
I think I'd always just prefer a loading screen rather than this cover up. I don't mind how Chrome on iOS does it where "dead" pages that are really just jpegs are in gray. That way you get an idea what they are, but also visual indication that this isn't actually a real web page.
Windows Phone 8.1 did the same thing. Don't think I noticed this on my higher end Lumia 9xx phone, but a lower end 635, the images it took were actually low bitrate enough that you could sometimes see artifacting in the image until the real program loaded lol (not bad, more of a curiosity than anything...and boo to Microsoft giving up on Windows Mobile...I like it and iOS better than Android...)

Force quitting only frees up RAM.... only 10% will every understand it. I wish we had a setting in iOS to only allow 10 background apps and auto close the oldest... For RAM sake!

Not always. Or maybe it is an issue with 11.
My biggest culprit - Spectrum TV. It just tells you there is "a problem - try later" if you have too many apps in the TM.
As their rep told me, clean out some of the TM apps and it should run fine.
This is on an IPP 12.9 G2 and a iPhone 7+.
Running into it also on a test app - Heckfire. It will go into "Low RAM" mode - minimized GUI at times. Clean out the TM, and back to normal.
Also run into issued with Office 365 on occasions. Same fix.
It exists BUT it is far far better than a few generations back.

That is WEIRD. I've never run into that and it shouldn't be happening unless there's some scenario where a bunch of badly coded or nefarious programs are tying up all the RAM... (?) Should be no big deal for iOS to just dump enough programs to fit the new one-especially on a device with 4GB! Seems like something's going wrong somewhere.
