Apple's iOS 7.1.1 tweaks shown to extend iPhone battery life

post #1 of 36
Thread Starter 
The latest version of Apple's mobile operating system seems to have brought with it enhancements designed to ease strain on the iPhone's battery, as some users are reporting noticeable increases in uptime with iOS 7.1.1.

Battery


iOS 7.1 brought a significant dip in battery life, according to journalist Adrian Kingsley-Hughes, who has been tracking power consumption on his iPhone 5 since the handset's release. That trend has been reversed with iOS 7.1.1, he noted for ZDNet, with battery life returning to levels seen in iOS 6.

Specifically, Kingsley-Hughes's battery meter now comes in approximately 16 percentage points higher after a six-hour test. Where his iPhone dropped to about 61 percent under iOS 7.1, the same workload nets around 76 percent with iOS 7.1.1.

Kingsley-Hughes says his data is averaged over "many six-hour runs." He measures drops only from a full charge in order to eliminate the possibility of a non-linear discharge curve.

Apple has been seen exploring numerous ways to improve the battery life of its devices in the past, including changes to the hardware itself that would lower power consumption. One notable invention, first discovered by AppleInsider, would monitor the device's charge and discharge cycles and use that information to alter various parameters -- such as screen brightness or the CPU clock speed -- to conserve power based on what it predicts the user will need.

I have no problem with overall battery life. The problem I have every once in a while is a complete shutdown for no reason when my percentage is showing between 15 & 20%. Sometimes I can power on again and other times I get nothing but the battery image showing a sliver of red along with the lightning connector plug. All other times I can run down to 1% and she still runs fine. iPhone 5 running 7.1.

Why does Apple bashing and trolling make people feel so good?

I have exactly the same problem. Very odd and annoying.

Yes, but lots of people do. By most accounts 7 has been more eager to drain your battery than 6. Here's to hoping 8 has so clever battery life enhancements, even if simply optimisations.

 

Too bad the iPhone 6 is going to be so, so, thin. It's going look cool being so thin, but they could enhance battery life more if they weren't so obsessed with being the thinnest smartphone out there. Just as the iMac is now the thinnest AIO out there, but the speakers sound much worse than the previous gen, thanks to the funnelled-audio sounds. I literally switched to the MacBook Air from 9 years of owning iMacs because of this issue, as the reason I bought the iMac is I was a true AIO desktop guy. Even adding on speakers to it ruins he whole point of the iMac IMO, and I really think it was a bad tradeoff. True form over function in the iMac case.

Has anyone seen an increase in battery life for their iPhone 4S?  I'm hoping so as my 4S  was drawing down at an incredible rate after installing iOS7.1

Frustratingly my 5S and my wife's 5 have both seen a decrease in battery life since upgrading to 7.1.1. We often get the 20% warning mid-afternoon where normally it would come around early evening!

@dickprinter

same here. it was described as a bug with a patch soon.

I still need time to know if it happens again with 7.1.1

7.1.1 was released Tuesday so just how many "afternoons" are you talking about here? One? Two?

 

FWIW: My current numbers at 3:39; 83%, 1 hour 8 minutes of usage, 5 hours, 50 minutes of standby starting at fully charged and plugged. On a 5s running 7.1.1 with all the radios enabled, LTE, cellular data, WiFi, Bluetooth, location services.

Your battery might be shot. Apple stores will diagnose it for you. My dad's iPhone 5 had this issue.

I had this same problem with my iPhone 5 when going from iOS 6 to 7. Eventually AppleCare replaced the phone after showing the problem still after a complete restore as a new phone. My replacement phone has no battery problems.

I find the speakers on my 27" iMac is surprisingly good. But really, the requirement (for me) is just that it is usable. I don't great audio from any computer, laptop, phone or tablet. If you need good audio you need external spacers and it was always thus. I bought my kids bluetooth spacers for their phones / iPads but they NEVER use them. They can be screwed with the charging and the setup etc. I think they have ridiculously low standards but they are happy. So my ever so slightly higher standards wasted me a couple of hundred bucks. :no:

I had this problem after I upgraded to iOS 7, and my phone was replaced under warranty. The Genius said my battery was failing.

post #13 of 36

I've had battery crashes with previous laptop batteries back when they were removable. Display a reasonable remaining level and then, splat. Something in the controlling electronics goes bad as I understood the tech: if under warranty I'd get it looked at rather than put up with the uncertainty.

I have an odd battery problem as well. The total usage time down to 20% seems to take the same amount of time as before but if I turn it off with around ~55% left the battery will show ~25% when I turn it back on and not move for an hour or so and if I plug it in the percentage will jump into the 40's

I dont see the battery drain issue as much, what I have noticed though with 7.1.1 is the phone becomes hotter performing the same operations as 7.1.

I just want to reinforce what @Sporlo, @jabohn, and @Mazda 3s stated. Get your iPhone checked out and push for a replacement or battery change. This is not normal. This is not an iOS bug.

7.1 was far worse on battery life on my iPhone4.
Stop laughing.
Much better with 7.1.1

Hey no laughing here; that was and still is a classic, quite beautiful design. I don't regret putting a case on my 5s (I resent the added weight but not the esthetics) and I always did when I slipped my 4s into one.

I've had that problem as well, which I thought was really bizarre. I plan on installing this update and see if that helps, otherwise I'm going to follow Solip's and a few other's suggestion and see a Genius. The Apple Store I go to gives excellent support and never an argument about anything, even though I am well out of warranty. I think the Geniuses have been given the directive to not even question a hardware issue except in the instance of 3rd party screen replacement or water/moisture damage. Samsung, et al. turning up the (competition) heat, I'm sure, is the motivator there.

After these updates, I always find my bluetooth turned back on.  Same applies for iPads as well.  I find turning it off helps.

I know it is a pain, but I think you guys should do a clean install, and set them up as new devices.
post #22 of 36
Sadly, 7.1.1 did nothing to fix cellular battery drain issue. At my home I%u2019m forced to disable mobile data (despite having robust WiFi connection) to prevent my iPhone 5s getting warm and drying up battery in realtime while idling (from 100% to 20-30% for 8 hours of doing nothing). The reason? Nearest 3G tower of my cellular provider have very poor internet connection. And still my iPhone insists on keeping alive cellular data connection despite being always on WiFi. It%u2019s not the battery %u2014 @ other locations battery life is excellent. It is inability to disable power-hungry and useless connection in place of low-power and fast one.

Let me get this right, you switched from an iMac because it had crappy internal speakers and your solution was to replace it with a MacBook that also has crappy speakers?

Seriously, it doesn't matter what computer you buy they all have rubbish speakers, just some are slightly less crap than others.

If you care about sound plug in some B&W MM1's or use a pair of decent headphones.

I double that the 20% to 0% has anything to do with the battery failing, as this didn't happen to me when I was on 7.1.
I think that 7.1.1. is the bug.
post #25 of 36
What is with Apple using 1000 cycle batteries on laptops and only 300 cycle ones on iPhones?

That is less than one years use before the KO approaches for many. That matters little phones with a battery hatch.
It just pains.

Just keep in mind that when everyone was speculating about the iPhone 5 design, there was case manufacturers who made thousands of "tear drop" designed cases (iPhone 5 rumor at the time)in anticipation.

http://www.gizchina.com/2011/10/04/iphone-5-cases-point-tear-drop-design/

So this could all be quite different by the time they release the phone.

They even went as far as making a physical mock up of what everyone was sure to be the iPhone 5 http://www.gizmocrazed.com/2011/09/first-rumours-based-physical-mockup-of-iphone-5-created/

I have an iphone 4s and noticed almost no battery loss when sitting unused all night . huge improvement over 7.1,

post #28 of 36
I've had terrible battery life on my 5 lately. Something is sucking it down to 50% by lunchtime with or without use. Turned off notifications, background app refresh still no help. Turning off icloud services has helped somewhat, but 7.1.1 has done nothing to stop it. Guess I'll try a wipe and restore.

Funny how in the news this morning this wasn't mentioned but how installing 7.1.1 causes a black screen and then you have to restore your iPhone losing all pics, apps etc. Report came out of Britain.

Of course when you restore an iPhone that's been properly backed up: you "lose" precisely nothing. No wonder they lost the empire.

You have a faulty battery. I had the same thing, took it to a Genius bar and had it replaced for free. They have equipment which instantly show if the battery is faulty.

I think sometimes a rogue app can drain the battery if you're unlucky. Also, run the iPhone down once a month to keep the battery calibrated. If you're noticing battery drain, try turning the iPhone completely off and on.

Ha, yeah I am not laughing.  My wife and I both have the 4, going on 3.5 years now, we will probably upgrade when the 6 comes out.  That being said, I did see improvements from 7 to 7.1.1 in battery life.  My wife's phone is still on  version 6 and she seems to have poor battery performance.  I wonder if an upgrade to 7.1.1 would hurt, or help?

Oh boy, if your wife has had an iPhone for three and a half years, the battery will be inevitably worse. I would certainly upgrade to 7.1.1 for the last few months of its life. I've read more than one report saying that 7.1.1 is comparable to 6 in battery life. To help the battery as much as possible, make a note to completely drain the battery once a month.

Edit: my iPad 2 is almost three years old, and I'm very pleased with how well the battery has held up. It's not as good as it used to be, but still easily gets through a day and then some.

In bed, 6 minutes before the end of a TV episode I got the 20% warning on my iPhone 5s. I turned to discover my charger cable was missing. I decided to try and finish watching the episode, put my phone to sleep, and tried not worry if my iPhone 5s would make it until the morning to wake me up with the usual alarm. 6 hours later I woke up to the alarm, checked the battery which had only slipped down to 15%. 5% battery drain from 6 minutes of video plus 6 hours of standby. Thank you iOS 7.1.1.

Personally, I thought the speakers in the previous iMac design weren't good enough either.  But I don't think adding a set of external speakers to an iMac ruins the whole point of the iMac.  It's not like you are carrying an iMac around all the time -- just plug in some speakers and route the cables nicely out of sight.  You won't worry about it again.

 

It sounds more like you threw out the baby with the bathwater in this case.
