IPhone 5 battery still draining after 6.1.2 update

I just upgraded to a brand-new iPhone 5 that had 6.1.1 already installed.  When I got home I updated to 6.1.2 and soon noticed that the battery was draining fast, like I was streaming video or constantly downloading, even when not in use.  Last night I had about 40% battery charge when I went to bed and when I woke up 7 hours later the phone was dead with the battery completely drained.  What is going on?!?

You may want to give Apple Support a call, but here are some things to check first:
1. Screen brightness
2. Bluetooth on when not in use
3. Location services running that's not needed
4. Push notifications for email accounts
5. Close running background applications
6. Use wifi as much as possible instead of cellular
7. Limit notifications from certain apps like Facebook, Twitter etc.
Take a look at http://www.apple.com/batteries/
If you limit these and the battery is still draining I'd recommend calling Apple Support or visiting an Apple Store.  Hope this helps.

  • X201: battery still drain after shutdown and unplugged

    This is really a confusing problem for my new X201. Everything goes very well, except for this battery drain problem.
    Generally I'll completely shut down my laptop and unplug it after one day's using, but when I open it the next day, battery will drop 7 or 8 percent to 92% or 93%. If I left it unused for more days, battery dropped even more.
    I don't think it's a battery problem, because if I remove battery after shutting down my laptop, and reattach it when I want to use my laptop, it won't loose any power. So, it means even when I shut down, my X201 is still comsuming power.
    Another proof is when I shutdown and unplug my X201, all lights go out. But shortly afterwards, the power light (not battery light)begins to blink slowly. I presume some devices may still consume battery power.
    According to some instructions, I used "powercfg -devicequery wake_armed" to turn off all wakeup devices, but it turned out to be of no use. I googled and found it's not an individual case. So, could anybody give me a solution? Don't tell me to remove battery every time.
    Thanks.

    Hi, did you guys ever found a solution? I just bought an used Thinkpad X201s from ebay and it has this problem too. I've tried everything: disabled everything in BIOS and disabled fingerprint reader, wake from lan etc. in the Windows 7 Pro. I also tried the newest BIOS with no luck. The power led will blink even if just visiting BIOS and then shutting down the machine from the power button (without ever visiting Windows after battery reset). I'm pretty certain that I've tried every trick there is as an end user.

  • IPhone 4 battery still draining fast after ios 5.0.1 update

    5.0.1 update did not help, my battery still drains just as fast as it did on 5.0. My phone used to last 2 days no problem, now it lasts about 6 hours, I could go to bed at 5% and wake up with 3%, now if I got to bed with 25% it's dead by morning. I have all iCloud services turned off, only Maps turned on for location services, notifications for Phone, Messages, Reminders, Calendar, CNBC RT and Words Free. I have 2 email accounts, one is a pop3 and the other Exchange, both are set to pull every hour and preview is turned off. Is the issue with notifications? the only thing that has changed from 4 to 5 is I have notifications turned on and my reminders & tasks are synced with Exchange. I'm starting to think the issue is with notifications, I tried to turn off email notifications for the lock screen but they still show up.
    Are we getting another update after 5.0.1 soon for the continued battery drain issue?
    Email notifications continue to display for locked screen even though the option says Off, is there something else I'm missing?

    Do we really need another thread, with over 7,000 posts already on other threads?

  • Ref:iphone 3G.I was visiting the US last week.One day my iphone battery completely drained overnight.I re-charged it but ever since it has either come up with a message saying it's registering, or that I need to register it.It was registered years ago.

    Ref: iphone 3G. I was visiting the US last week.  My iphone battery completely drained overnight. I re-charged it but ever since it has either come up with a message saying it's registering or saying I need to register it.  I'm concerned that if I re-register it on itunes I'll lose all my data.  I originally registered it a couple of years or so back, when it was new.  Any advice much appreciated.

    Thank you for quick reply.  The data is still there - every so often when I switch it on, it comes up with the main icon screen, rather than the emegency calls only screen (which it does most of the time), and I can get to my contacts, photos, and so on, but it won't connect to any mobile/cell network provider, including my network here in the UK - O2.

  • My factory unlocked Iphone 4 got locked after 4.3.2 update, How do I unlock it?

    "factory unlocked Iphone 4 got locked after 4.3.2 update, How do I unlock it?"
    Do I have to use the apple's fast lane to resolve the issue or is it something that can be resolved quickly using the ITunes or combination of power and home key please advice...

    From where did you purchase the iPhone? Are you certain it really was factory unlocked? I can't say that an iOS update couldn't inadvertently lock an iPhone, but more commonly it would happen with a jailbroken iPhone. If by "from Irvine" you mean Irvine, California, then you don't have a factory-unlocked iPhone unless you purchased it from another country, as there are no unlocked iPhones sold through any authorized reseller in the US.

  • Pls. help: iPhone 4s battery still bad after replacement

    I got my iPhone 4s 64GB on day one as it became available in Europe. It was a big investment for me, so please help me find out what I should expect from the device.
    First some background. I've had all iPhone models thus far, so I'm not new to the game. Also, I tried messing with the settings as described in many sites. Nothing helped. So I waited for 5.0.1. I installed it and it didn't help at all. It didn't make things worse or better. I then saw my wife's iPhone 4 going incomparably stronger with the same settings after a year and 3 months of usage. Basically her battery would go down to 92% compared to mine going to 72%, whilst she was even making calls and I just had mine in sleep.
    So I decided to give up, and after discussing my issues with Apple Care conceded it *could* be a hardware problem and sent mine in.
    I received my replacement iPhone 4s yesterday. I charged it fully and put it on my night stand at around midnight. Also, I made sure I didn't even restore my previous iPhone, but rather set it up as new, just entered my iCloud data and turned off the location services, etc. At 7 a.m. my battery showed something over half. It's noon now and after no phone calls and only checking a few emails my iPhone battery is deep in the red.
    I'd appreciate your help, testing, opinions. I'm at loss whether this should be considered normal, because sending in device after device doesn't seem right to me and perhaps makes no sense.

    Just one thing:

  • Why is os 6 upgrade causing my iphone battery to drain?

    Why has the os 6 upgrade caused my iphone 4 battery to drain unusually fast?

    when I use the computer usb port to charge the battery, I found something strange:
    battery indicator is showing 100% from my iphone within a hour
    battery indicator is still showing "charging" from iTunes after two hours.
    After two and half hours, the battery indicator is showing "charged" from the itunes.
    The battery indicator might make you think your iphone's battery is fully charged from the iphone but it doesn't.
    I had same problem from my 4s after upgarded to iOS 6 but Charged the battery overnight or more than two or three hours and it works fine now.

  • New battery still drains while not in use

    A few months ago I noticed a battery performance issue on my 1 gen nano (quickly discharged, drained while not in use). I bought it the day they were available in stores (which was in 2005) so assumed I just needed to replace the battery. I installed a new battery and fully charged it with the ac adapter. However, I'm still having the same problem. After some troubleshooting, I found that it played for 5 hours on a continuous loop with no EQ and backscreen light off. The battery was fully drained. I again recharged in with the ac adapter to make sure the battery meter was recalibrated. After it was fully charged again I placed it on my desk and didn't use it. However after another 5 hours or so it was drained again. This is my second purchased battery so I doubt it's the battery. I have restored the nano numerous times. Any thoughts as why a new battery would drain while not in use? Could this be a hardware issue? Thanks in advance!!

    You either have an alarm set in clock or calendar which is causing it to play while you think it is off or you have a logic board short. I'd bet on the latter. You can have it diagnosed at http://www.iresq.com for $9 or Google for other 3rd party repair sites.

  • IPhone battery got drained to 0 by low network

    My iPhone 4 had abnout 75% battery today. I went in to a place where the wifi and cell phone network was very low but occasionally visible. It had not been connected to the local wifi at all.  In a few hours, I realized my phone was completely dead - drained to 0 and off.  I assume it was because it was trying to get hold of the very low cell phone signal (and/or wifi) - that was way too fast to drain 75% of my battery.   Is this plausible and if so, how do I prevent it?  It's terrible to think that just by going somewhere with poor signal, it can drain my phone super-quickly, for no useful reason (I wasn't trying to use it!), without telling me. Surely there must be a way to disable this?

    The magnet in the cover "could" cause lower reception and thus cause the EDGE or 3G antenna to use more power to boost the signal causing the battery to drain faster. It's a known fact that an iPhone will eat through battery in low 3G areas, with 3G on, trying to maintain that 3G connection.

  • IPad Mini will not boot after battery drained after IOS8.0.2 Update

    I upgraded to IOS 8.0.2 having skipped 8.0.1 two days ago. I did not notice any unusual problems, but with hindsight a few apps did crash out on occasions, but not consistently.
    Yesterday night I let the battery completely drain and I plugged it in to recharge overnight.
    This morning I find that logo is still on screen and it doesn't look as if the iPad has recharged. I have tried re-booting a number of times, but it will not progress beyond the Apple Logo. I have tried connecting to iTunes on my Macbook Pro, but no device is recognised.
    Having left the iPad sitting next to me while still connected to a charger, I have noticed on a couple of occasions a flash of blue screen followed by black and then the Apple Logo appearing again.
    My iPad Mini Retina 128Gb appears very dead at the moment. Any suggestions on revival?

    Try to put your iPad into DFU mode and do a full restore this way. To do so, follow the steps below:
    1. Open iTunes on your computer
    2. Connect your iPad via USB.
    3. Press and hold the Sleep/Wake and Home buttons for about 10 seconds.
    4. Release the Sleep/Week button but keep pressing the Home button until iTunes shows that it has detected and iPad in DFU mode.
    5. Try restoring your iPad.
    If this won't solve your problem, and you are not able to do a restore via iTunes at all, then take your iPad to an Apple Retail Store because then it is possibly a hardware failure. Here you can find the service options: https://getsupport.apple.com/ProductSelector.action

  • Batter drain after 6.1.2 update

    My 4s was the third replacement from apple in 2 months because of battery drain after 6.1.1 was released. This current phone did not have the 6.1.1 update installed on it and I did not install it. My battery would maybe get to 60% after being off the charge for 18 hours. Yesterday I p,urged it into iTunes for the first time and it did the 6.1.2 update AUTOMATICALLY and now the battery only lasted from 7 am to 11 am and it was at 20%. I did not change settings, I did not I stall any new apps, nothing changed except the apple software. I have reset the phone, turned off the cloud, set it up as new, and still have the same issue. When going and looking at the usage, before the update my usage time and stand by it ex would be what you would expect, usage 2 hours ans stand by 12 hours, or something close to that. Noe the usage and standby are only 9 minutes different. What in the software is causing it to run continuously and preventing it o go into standby???????????

    The same thing has happened to my wife's iPhone 4

  • How do I restore the contacts in my IPhone?  They dissappeared after I did the update.

    After I did the update, my contacts comletely dissappeared and my email locked up. Any help would be appreciated. I contacted Apple, but they were not of much help. The Icloud was not of help either.

    Do you have sync contacts with the Address Book on your Mac selected under the Info tab for your iPhone sync preferences with iTunes?
    If not, this needs to be selected.
    If you want to replace contacts on your iPhone with what is available in the Address Book on your Mac, select Contacts for replace info on this iPhone under the Info tab for your iPhone sync preferences followed by a sync.
