battery drain fast after ios 8 update

Please, everyone posting links to "handy tips on saving phone battery" sites, stop. This is most definitely an issue with the last update, not a situation where people need to optimize their phones. My phone was working perfectly fine prior to the last iOS update, now my battery is drained before lunch (after a full charge) and my Home and Lock screen is using up 59% of that battery power. There is quite obviously something wrong with the last update.

I Am experiencing exactly this problem. iPhone 4s was fine until 8.1.1 upgrade, now having to charge twice each day and overnight. Mostly the battery usage says the Lock screen is causing the problem. Everything is turned off - even the phone!!!! Ridiculous situation.

i Wish Apple would do something about this. I can't even turn the **** thing off - it keeps turning itself on again! I'm now looking at how difficult it will be to move to an Android phone.

No. There's not. It's your device hardware or your usage. If you've tried all the optimization tricks and it still doesn't work, then it's your hardware. If it was the software, then everyone (literally, everyone) using the same iOS would have the same problem.

Use this procedure:

- First, charge up the device to 100%. To enable the percentage indicator, go to Settings > General > Usage, and turn on Battery Percentage.

- Once the device is charged to 100%, make sure to close out all Apps that are running on the device. In iOS 7/8, you close out running apps by double-tapping the Home Button, and then swiping your finger up across the preview screen of each app to move it off the top of the screen.

- Then, turn off Wi-Fi, Bluetooth and cellular data. Settings > Wi-Fi > Wi-Fi: OFF, Settings > Bluetooth > Bluetooth: OFF, & Settings > Cellular > Cellular Data: OFF. This will not prevent you from receiving any phone calls.

- Go back to the Home Screen, and take a screenshot. Press both the Sleep/Wake button and the Home button together briefly, and you will see the screen flash white for a split-second, and an image will be saved to your Photo App Camera Roll.

- Disconnect the iPhone from the charger, and lock the screen so it is dark.

- Let the iPhone sit in this ‘standby state’ for as long as possible, preferably overnight. No apps running, no internet connection, not connected to power, and the screen locked.

- In the morning, unlock the screen, and then take a screenshot of the Home Screen again.

These two screenshots will help to document how long the device was in standby mode, and how much battery percentage was used. If it's not more than 1% per hour or so, then there's nothing wrong with your device, and it IS your usage.

"If it's not more than 1% per hour or so, then there's nothing wrong with your device, and it IS your usage."

And if it's more, say 20% per hour, what then?

i had same problem on my i5, home and lock screen uses ALWAYS a lot of battery, about 16 - 25%. I have made all tips and recommendation for improving battery life, but it doesn't help. All what i do with phone now - checking news w safari calls and music. All this apps takes from 5 to 15% of battery.. Looks like this is problem not with device, but with iOS
I'm disappointed

To do my best to diagnose my own issue, I have wiped off my iPhone 4s and reset it to factory settings. I've disabled Siri, location services, and have no 3rd party apps running.

My battery will drain in about 4-5 hours, without being used at all - so the lock screen is basically draining 50-60% of the battery life, and a few background apps, like mail or draining the rest.

This obviously is not normal behaviour. Keeping in mind, that prior to me updating my phone, I had no issues with battery life at all. I would use my phone moderately, checking mail, the occasional app/game, take pictures, etc. and it would last the entire day. The last update completely screwed with something.

This fixed the problem. Thanks!

IM sure everyone apearicated you helpful hints, however there is clearly a problem. I went from having my battery last a couple weeks on my iPad to draining in a day or two. My usage habits haven't changed, however the OS has changed. You can't call it a hardware issues considering there are so many different models and within each model there are different generations needing different tweeks in the software for soother compatibility. This is preaty much confirmed in my household because my wife and sons all had different issues with the update. From slowing devices to a crawl to calls not being able to be made as normal.

You are maybe one of the lucky ones that the hardware you are using is more compatible than others.

OK - there's clearly a lot of concern about this amongst iPhone users, particularly the 4S. I'm in the market for an iPhone 6 but this has made me step back and think about Apple as a vendor and how they support their products.

It seems to me that they may be struggling to manage their legacy devices (i.e. older iPhones and iPads) effectively. I don't want to have to pay for a new phone every time a software update is inadequately tested on legacy hardware (if indeed this is what has happened here). It's this lack of proper testing on legacy devices, like the iPhone 4S that causes problems with iOS updates.

I have an iPhone 4S that is now barely usable because something in the core iOS software is draining the battery so fast that the phone physically heats up.

Apple will not focus resources on fixing this problem unless the user community gives a clear message that we're not idiots and we're happy to bring evidence and metrics that demonstrate the problem. So all of you who have this problem - take heart that if you keep repeating the message, not just here but in other forums and public sites, Apple will eventually hear you and allocate resource to fixing the problem.

Me - I'm seriously considering Android or Windows and evaluating how hard it will be to move all my investment and ongoing subscriptions in Apple technology.

"it IS your usage." ......... or the software. Not sure anything that was written there absolutely ruled out the possibility that it is the updated iOS effecting battery usage on the 4s.

Some peoples troubleshooting skills can certainly be questioned here..

His suggestion never once questioned the fact the iOS update could be at fault..

If you didn't have the problem before the update and your "Usage hasn't changed" and your battery drains repeatedly. Even after optimizing your device as a trouble shooting step how can you not question the update. If that's the case Apple has sold a lot of people defective hardware based on his response.

I hardly use my tablet now becasue the battery drains so quickly.. I can leave it in standby after a full charge and it will be nearly dead by the evening... I used to be able to stream Hulu for nearly 6 hours I am lucky if I get two out of it now... I guess my hardware suddenly became defective right after the update.

I wouldn't usually consider myself in the conspiracy theory camp over this sort of thing, but if this was any other company than Apple, I would suspect that they were intentionally crippling older devices in order to drive Christmas sales of new hardware. It sure feels like that sometimes. This kind of bug feels like it simply shouldn't be getting through the screening process of one of the most financially successful company in the world.

Jpetreman it seems like that sometimes...

I have witness over the years what I consider Apple standard behavior. Please note most of the below items are factual things that Apple does so if it upsets a diehard Apple user, please dont let it bother you becasue im not here to compare what is better or worse. I use my Apple products everyday and there is almost a religious culture that Apple has manifested since the beginning that us users expect a higher standard from them and we get disappointed when that standard seems to have not been meet.

1- Looking at software, they will be update programs only to make it less functional as it predecessor and slowly reintroduce the features bringing it back to what it was. This goes for OS platforms as well. Not sure if this is by design or if its an attempt to give them time to make sure older hardware is still supported.

2- Introduce a new phone or iPad what seems to be every six month to a year. (Sure helps the bottom line when everyone rushes out to go by it. but not the folks that hold on to the older stuff becasue it still just works like it should.)

3 - Release computer hardware with older technology yet keeping the prices at a standard high norm.. (for example 5400 rpm hard drives instead of 7200) why would you introduce a bottle neck on such a beautiful piece of hardware.

4- Drive the market to accepting hardware the way Apple feels it should be. (Still waiting for the 17" MacBook pro to come back so I can upgrade mine. or in other cases create a DVI display port adapter that only outputs pure digital making my two thousand dollar wacom completely useless unless I use VGA to DVI adapters.)

5- Apple store techs seem to make you feel belittled when you clearly show them an issue, and they want to claim its user caused. Being in the industry for many many years its very insulting when a young employee cant size up your knowledge level when going over an issue. Even after showing documentation proving there is an issue. I'm not claiming I know more than the employee, but I defiantly have my fair share of professional troubleshooting experience across several platforms.

6- Release technologies that doesn't seem to be entirely perfected. (Apple TV still cant seem to stream a movie from my Macbook Pro or iPad without getting all messed up. even after software updates using different wireless access points, and even hardwired. Just one of the few weird problems I have encountered using the little critter... Very frustrating.

7- Some of the worst file management when dealing with the OS software, it seems every application wants you to not really know where your files are. Then you are expected to rely on the Time Machine when it goes south. Of course other will disagree and that's fine, this is my personal feelings on the matter. I feel like I am using Windows 3.1 sometimes when dealing with files directly..

The list goes on but I dont want everyone to feel I am bashing the product becasue I do enjoy most of my Apple equipment. On the lighter side of things the hardware is rock solid on most devices when it comes to construction and reliability. Battery life is still superb on my MacBook Pro even though I have had some hardware issues with it in the past. Apple did fix it but still had to fight with them some on the matter.

I still find I am much more productive on a windows based machine, but find myself trying to use the track pad as if I was on my Mac at times. Regardless I still use my Mac as an everyday machine unless I am working on something that requires my PC. I ask myself why sometimes after dealing with all the little annoying items and it seems to boil down to the overall construction of the hardware. It turns on and works, except for my iPad now, I have to worry about if I put it back on the charger...

Anyway I hope Apple will improve some of the legacy support, but there has been I believe at least 3 small iOS 8 updates and still suffering from the battery drain issue.. My wife's phone seems to preform better now after the first update was released, and I have heard some of my fellow employees say their iPad 2 is running as it should now.

But like mentioned earlier by a fellow Apple user suggesting it was an Hardware and or usage problem, I had to snicker at the fact that so many where having issues how could one even suggest that's where the fault was.

Similar to another user who posted here, in addition to the battery drain which occurs even when in flight mode, my phone will not switch off since the update to iOS8. So, in addition to having to constantly recharge and having to have my phone plugged in all night if I want to be able to use the alarm, I can't even switch the bloody thing off to save battery! I had a completely functional iPhone 4S with iOS7 and now I have one which is barely worth having. I wouldn't care if they let us downgrade back to iOS7 but apparently it's too late for that now too!

Yep My phone will no longer turn off either, It turns off then just reboots. iPhone4s 64gig
