Battery issue with iOS 8.2

i have ipad 4 with retina display. Since my upgrade to newer version today to IOS 8.2 .
I Have notice this more than anything my BATTERY IS DRAINING TOO MUCH FASTER NOW, n heating up faster too.
before that I did had issue with battery since upgrade to IOS 8, but now typing this msg 1% is gone. Same for when playing games, watching movies n other work. The drawing time have increased a lot. And I am using my iPad without my cooler master cover too.
please have this fix ASAP. And where is the health app ?

Same here, i have a similar issue..
My iPhone 32Gb 5s (ios 8.1.3) facing this issue too, the battery precentage jumps when using at 61%-59%, 55%-53%, 31%-29%.
I also facing this issue too when it was 8.1.2..
When the precentage shows 59% on the iPhone, i charges it to the iTunes on my MBP, then precentage on the itunes for a while shows yea, it is true 59%.,
I'm waiting for about 3min, the battery precentage on iPhone shows it STILL at 59%, BUT the precentage showed on iTunes is 60% !! And the next 3 minute, the battery precentage on iTunes shows the battery up into 61%, AND when i look the battery precentage on the iPhone, it was JUMPS from 59% directly to 61% !! (that's not showing 60% on iphone)
I assuming it just an iOS wrong battery precentage. (the battery actually isn't broke)
Because when the iPhone unplugged and the battery precentage on the iPhone shows 61% for a while, ACTUALLY at the moment, the battery precentage is JUST PASS THROUGH 60% first, before it turn to 59%. And yea, there's the main trouble, the 60% battery precentage isn't show on the iPhone.
I already do a hard restart the iPhone, calibrate the battery, and even restore the iPhone but it doesn't work.
i Hope in the next 8.2, this issues can be solved.

  • IOS 6 battery issue with iphone 4s

    My Battery is getting low in drastically

    Good to see others have the same problem...  I started with 65% this mornig at 7 am - now, after some whatsapp and aprox. 5(!) minutes of gaiming I'm down to 36% at 10 am...  what's going on?
    Under iOS 5 I could use it more than a day including calls, whtasapp, safari, etc etc
    I already used some tips&tricks, reseted the phone - nothing helped.
    Have the 4S
    I'm really a fan of Apple Products - but this aongoing battery issues with my iPhone are daisappointing me more and more... I do not want to turn of all the services that make the iPhone what it is - otherwise I could use my 6 year old HTC or something....

  • Severe battery drain with iOS 8.1.2

    I am having severe battery drain issues with iOS 8.1.2 with all my iOS devices (iPhone 6, iPhone 5s, iPad Mini Retina, iPad Air). I can have my device in DND mode overnight with 100% battery, then the following morning I will wake up to find my device down to 20%. The battery usage graph shows nothing abnormal, just very rapid battery drain. What gives?! I saw a couple other threads mentioning this issue. I have attempted Network Reset and verifying Bluetooth is off, but this is just crazy. Anyone else get a resolution on this or experience this after iOS 8.1.2?

    tldr; Check the secd process on your Mac. If it is consuming greater than 50MB of memory...turn off Keychain sync on ALL your devices.
    The Full Story
    The last few months I've had instances where my iPhone would start getting really hot in my pocket, and the battery would drain at 3x the speed. After much research I also discovered that a process on my Mac (secd) had a vicious memory leak and that single process was consuming 13GB of memory and paging thousands of console messages. After discovering that the process was related to Keychain sync, I disabled keychain sync across all 5 of my devices. Immediately, the battery life on my iPhone was restored to normal.
    After I reenabled Keychain sync across all my devices, everything would run fine for a while, but after a few weeks, the problem would resurface. And I would repeat the process of turning it off on all my devices, to effectively reset the iCloud keychain data.
    Anyway, Apple does need to fix this, as it affects performance on both OSX and iOS.

  • When will these issues with iOS 8.0.2 be fixed?

    Admittedly, this problem has been going on since Apple released the core iOS 8 software, but it's glaring (worse) here. Let's go to the beginning.
    I own an iPhone 4S 8gb and upon release of the core iOS 8 software, I installed it like a fool and I didn't know that a lot of problems came with it, so the next morning, my iPhone's internet (connected to a WiFi network) was shotty as sin and I really needed it at the time because of a Transit thing I was doing until recently. The features that came with the iOS 8 is impressive, but I also was shocked when I couldn't even listen to my music for a whole day (I fixed that when I hooked up and synced in iTunes), despite my library having the same number of songs before the update on the iPhone. Now, I've heard of these problems from a friend who apparently works for the Apple tech department days after I discovered them myself, so I waited for the next update in hopes that it'd fix all of the core iOS 8's problems, but... short and to the point, this update is even worse than the core software. Problems include, but not limited to:
    Safari lags like crazy at times, especially when you're trying to type something. Also, Safari seems to not direct you to Google unless you searched for the topic again; I don't like doing that. I like typing in a research topic in Google's engine only once.
    Siri is much worse than the 7.1.2 software; the assistant can't tell what you're saying 69% of the time. I'm also not pleased with holding the home button to speak to the assistant and continue holding it until you finish speaking to her/him.
    Apps freeze and become unresponsive and in common cases, they crash in the middle of the night (a perfect example would be YouTube) while I'm sleeping (not 100% sure who's to blame for this, Apple or the app developers themselves).
    (refer to the lagging Safari bullet) The keyboard lags on you badly and I'm not just talking about Safari, this problem is every where you need the keyboard in, including basic texting in iMessage.
    The Music app apparently can't judge your selection at times, like, when you select a song from your library, it takes 3 hard pushes on the touchscreen to select it and sometimes, it randomly selects the next song under the one you want to listen to.
    Did I mention the constant lag?
    I'll probably find more problems as I scan though the iPhone tonight, but above are the main problems that I have with 8.0.2, not 8. I know what you're probably saying: "Why not just downgrade back to 7.1.2 where you didn't have barely any problems at all with your iPhone?" Well, apparently, Apple stopped signing the software when I tried to restore the iPhone in iTunes to that firmware, so I find it completely pointless to try to downgrade. My core question is "When will these issues with iOS 8.0.2 be fixed?" I know the iPhone 4S can work with the newest iOS, because, if it wasn't, iTunes wouldn't have notified me of the update. I was thinking of getting an iPhone 6 or 6 Plus June or July of next year, but if the software is still buggy at the time, I'll stick to my 4S until my contract ends at the end of 2015

    Also, I've noticed that the 4S' battery life is horrible even if there's just music going on in the background. Common battery life for the iPhone is 3 hours (just having music and data active) and most of the time, I'd have to carry my USB charging cable with wall socket so I don't have to worry about it shutting down on the go and I know it's the software that's the problem because it wasn't like this prior to iOS 8.0.2 or even the core iOS 8. Common battery life for the iPhone on iOS 7.1.2 was atleast 7-9 hours on the same conditions as listed above.

  • Battery uses with iOS 4.2

    Hi,
    I have noticed a battery use issue after upgrading to iOS 4.2 My iphone and ipad battery is draining quicker than it did before the upgrade. For example, if my iphone (Model 3GS, 1.5 year old) was charged full and left idle for 24 Hrs, the charge drops just a few percent. I used to get 90-96% charge remaining after one day idle. Similarly, in ipad too, the charge will retain 85-95% if left one week idle after full charge. But after updating to iOS 4.2, the battery is draining quickly. iphone charge drops to approx 80-85% if left idle for one day and by 3rd day it drops to 20% if left idle. Similarly in ipad too the charge is dropping faster too. If kept idle for one week charge drops to some 70%. Did any one notice this? I am unhappy with this issue as it requires me to charge the devices quickly. Also the drain in charge is unreasonable as i have not used any extra feature which may use more energy.
    Thanks,
    N

    Are you sure? I'm using 4.2.1 and don't have any battery issues with mine.
    Did you check that nothing is running in the background? Some apps like Skype can still run in background even if you exit out of the app.
    Also try this:
    Delete your mail account by going to Settings > Mail. Once deleted, do a hard reset, by holding the home button and the power button for 10-15 seconds until apple logo appears. Then re-set up your mail account. Sometimes the mail server can get stuck.

  • Is there an issue with iOS 8.2?

    It seems like there are a lot of people that are experiencing issues with iOS 8.2.  I guess it was just a coincidence that this happened to me when I unknowingly updated my iTouch out of the box.
    Missing songs and playlists after update
    Nothing has worked to fix this.  Is there an Certified Apple representative on this board that can address this with all of us?  If so, what is the timeframe for fixing these issues?

    Does the iOS device connect to other networks? If yes that tends to indicate a problem with your network.
    Does the iOS device see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on your router
    .- Reset network settings: Settings>General>Reset>Reset Network Settings
    - iOS: Troubleshooting Wi-Fi networks and connections
    - Wi-Fi: Unable to connect to an 802.11n Wi-Fi network      
    - iOS: Recommended settings for Wi-Fi routers and access points
    - Restore from backup. See:
    iOS: How to back up
    - Restore to factory settings/new iOS device.
    If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • Has anyone had app update issues with iOS 8.1?

    I'm running iOS 8.1 on a iPhone 6+.  If I try to update an app from the app store without being logged in, it will hang the process and the update will fail.
    Previously, with my iPhone 4 and iOS 7.1.2 the app store would ask me to log in when an app update was attempted without being logged in.
    The work around until apple fixes this bug is to ensure you are logged in BEFORE attempting an app update.  An honest techie at the local apple store admitted this is a bug (one of many) in iOS 8.1.  Has anyone else had this issue with iOS 8.1

    Nope, I'm able to update an app in iOS 8.1, even if I'm not first logged into the iTunes & App Store in Settings.  It prompts me to update the app, then I sign in with my password.
    Do you have Touch ID enabled for App Store or not?

  • Battery Issue With iPod Classic?

    I have my iPod hooked up to my radio so it usually just charges that way, but I kept having low battery so I decided to charge it all the way and then reboot it and when I rebooted and the iPod turned back on it went straight "to low battery" or "no power remaining" and it never use to do this.

  • Issues with IOS and WPA2 Enterprise

    Hi,
    Done a lot of searching on this, but can't find anything useful!
    I've got a network running WPA2 Enterprise using AES and PEAP/EAP-MSCHAP-V2
    For some reason, all our apple IOS devices connect to the network fine and are able to accept the server certificate, but can't seem to access anything over the network such as the internet once connected. I'm currently testing an iPad mini with IOS 7.0.4
    I have other devices such as laptops and a Windows Phone 8 devices, and everything works fine.
    Am I missing something here? What could be causing the IOS devices to stop accessing the network?
    Cheers,
    Carl.

    I just found this on the frontline support site, I believe my question has been answered:
    Important Notice
    iOS Devices
    Apple has made a change to the PushMagic or UnlockToken values in that they may differ in size to previous values. This can cause issues with iOS devices being able to connect to the Afaria server as the current database field size is not adequate to facilitate the variable length of this value.
    Apple has made a change to the PushMagic or UnlockToken values in that they may differ in size to previous values. This can cause issues with iOS devices being able to connect to the Afaria server as the current database field size is not adequate to facilitate the variable length of this value.
    There is an Apple issue that we have found in our testing that occurs when iOS devices are enrolled. This issue fails a check when the enrollment payload is inspected and the signing cannot be read. SAP believes Apple will fix this issue prior to iOS 7.1 being released but we are working on a patch that will address this issue shortly in case the fix does not make the iOS 7.1 GA release.
    Afaria will be providing a patch to address this issue that increases the size of the database column from 2K to 6K to accommodate this change.
    This issue is resolved in Service Pack 3 Hot Fix 39 and Service Pack 4 Hot Fix 3. Available now.

  • Why doesnt the Ipod touch 5th gen have Battery Percentage with IOS 7?

    I read that the Ipod touch 5th gen will have battery percentage with IOS 7. But so far it doesnt. Just wanted to know if this was a lie or if something happened and apple decided to remove it.

    "Battery percentage in status bar added to iPod Touch (5th generation)"
    I seen this
    and i have seen pictures of the Ipod touch with the percentage next to the battery on the apple website.

  • Resolving battery drain with iOS 5 (not 5.0.1)

    Hi
    New iPhone user (first iPhone).  Unlocked 4s 64Gb.  iOS 5  United Kingdom
    NOT impressed with battery drain so far and reluctant to "upgrade" to iOS 5.0.1  On standby (most services set to "off") phone has decent life (looking at about a week bofore the battery dies) but as soon as I start using the phone - eg browsing over WiFi, battery drops like a stone (4% in 20 minutes).
    I can see lots of folks upgrading to 5.0.1 and doing a full battery drain, full reset & set-up as a new phone and this seems to resolve some issues. 
    My question is, does this same technique work with iOS 5??
    Hopefully 5.0.2 (or whatever it is called when released next week) will sort this out - otherwise the 4s goes back to store for a refund.
    Any comments gratefully received.
    Cheers
    RB

    I have also noticed what appears to be decreased battery life after the upgrade, though not this bad.  Seems many people are noticing problems. 
    I noticed and changed a couple of settings that seem to have helped.
    - first, fully shut off the phone and then turn it back on - i read online this helped some, immediately after the update.
    - in mail settings, for the icloud account (I dont use this but it was configured by default) check the sync settings . it defaults to push, which takes more power.  you might want to disable push and set to fetch for this and any other accounts you have, for additional power savings
    - in settings, location services, scroll to the bottom and tap system services : All of them are defaulted to on.  I turned off location-based iads and setting time zone since i dont need those. (I also opted out of the diagnostics and usage as part of the setup, but it was set to on in this screen - i left it on for the time)
    - also in settings -- location settings:  check the list of apps and verify that only the ones you want, are enabled
    These few settings seem to have improved things

  • Issues with IOS 8.0.2 on iPhone 6

    Hello  Users and Apple What is going on with IOS 8 and IOS 8.0.2 my iPhone 6 with the latest update my device while I am using apps my iphone does not respond also battery dies quicker. I aready follow troubleshooting articles from Apple Support but no resolution. Please Apple respond I went thru a lot rush and big lines for me to get a get a device the does not work properly. I think you guys had enough time to realease a Perfect iPhone after all that waiting and crazy lines on apple store. Please respond!!!!!!

    My wife and I are also experiencing intermittent issues with our new iPhone 6s. We both recently upgraded, she had an iPhone 4S and I had an iPhone 5 both of which worked very well and reliably. So far, in the week that we’ve had the 6s, we’ve experienced more app crashes and issues with iPhone remaining connected to our home and work networks. The wifi issues are occurring on both of our phones even after updating to iOS 8.0.2 so those issues have not been fully resolved. The app crashes we experienced initially seem to have been fixed after updating but, it’s only been a day. I’ve only owned iPhones as my last three cell phones (3G, 4S and a 5) and the 6 so far has the most issues. iOS 8 is also the buggiest OS to date in my experience using iOS. Not a great sign for the direction Apple is going in. The reason I’ve always preferred an iPhone to other available phones is that they’ve always worked exactly as promised and whatever few issues may have existed either with the OS or the device, they were fixed quickly. Unless another iOS update is forthcoming that truly corrects the remaining OS issues, for the first time since first owning an iPhone, I’m going to really begin to lose a little faith in Apple products. Between my wife and I, five iPhones, two Apple TVs and two Macbook Pros. As an example of the wifi issue I’m talking about, last night my wife was watching a show on HBO GO on her iPhone while she was preparing dinner in the kitchen. Her iPhone was connected to our home network as usual and as it always was with our previous iPhones. While watching the show, she gets a message stating that using 3G to stream shows could affect her data bill. Meanwhile, the wifi symbol was still showing on the top of her phone as if it was still connected to our home network but apparently, the phone was actually using our cell network to stream HBO GO. That obviously shouldn’t be happening and is definitely going to affect our cell bill big time. Neither of us have ever experienced these issues on our old iPhones. Very disappointing.

  • Anyone notice ALS issues with iOS 6?

    Since the recent update, I have noticed that on iPhones and iPod touches alike, that the Ambient Light Sensor seems to be real slow to respond to environmental changes... sometimes not at all.  No case used.  I will say it seems to transition between lower brightness and higher brightness okay... but the reversal doesn't seem to happen at all.  This happening to anyone else?

    Thanks for the response. I'm a bit surprised no one else has responded to my post but I'll check out that discussion you linked to. I have also submitted feedback to Apple regarding this issue under iTunes and iOS 6 so I hope you do too.
    I find it bizarre that such an obvious bug would not be noticed before they released iTunes 11 and/or iOS 6. I've also noticed a few other issues with iTunes 11 like the store not always connecting so I have to close the app and restart it and then it connects. I also get delays and beach balls sometimes when simply selecting a song or video. Anyway, that belongs under iTunes.
    I have to say though that other than that issue I am extremely impressed with the performance and reliability of my iPad 4. Coming from a 1st gen iPad to the 4 is a night and day difference. Everything about it is much quicker, such as wifi, cell service, even on 3G, and things like browsing and opening and using apps. I'm no longer using my little Windows laptop as browsing is just as quick, if not quicker, on the iPad. Even the battery life is better. Charging is not as quick but certainly much better than I experienced on the iPad 3 when a friend bought his and quicker than my laptop.
    Thanks again for the response.

  • When will you fix battery issues on ios 5.1.1? I have the same settings but 85% less battery life!!!

    I have read many tips about what to do for increasing battery life. However
    I hav the same setting with ios 5.1.1 that I was using with the previous
    version (ios 5.1) but with 85% less battery life time. It is so frustrating because this
    issue come back every 2 update : one killing your battery and the second
    to fix this, and it starts again... I am really sick of this.
    I am using an iPhone 4.

    Hi All – I have also experienced the battery drain issue on upgrade to 5.1.1.
    Like many on the forum I have tried ALL suggestions to resolve this issue, none of them have resolved the problem that Apple owners seem to be experiencing, it’s not in our minds as some suggest. My iPhone 4 and iPhone 3GS are working a treat under 5.1.1, in fact I believe the 3GS is running better than under 4.3.x.
    However I do think I have tracked the problem down, which I will document here, but first a list of the things I’ve tried:
    - Fully discharge battery to <5% and then back to 100% and leave charging for 3 hours after
    - Turn off all notifications
    - Turn off all location services
    - Turn down brightness
    - Turn off ALL iCloud services (effectively delete the account)
    - Reconfigure email account to ‘MANUAL Fetch’ only
    - Factory restore to fresh 5.1.1 from within iTunes and then restore from back-up
    The only thing that stops the battery discharging at around 5% every 8 hours is turning off Wi-Fi during standby mode. Prior to 5.1.1 the iPad would drain maybe 1% every 24 hours in standby mode with Wi-Fi on.
    Puzzled by this I did some research to understand what the iPad is doing whilst in standby mode with Wi-Fi on, so below is a trace from the iPad system log so that hopefully someone can look at this , identify the issue and hopefully fix it in a future ios 5.1.x release:

    These repeating messages appear approx every 30 seconds the wakeup packet contains the MAC addresses for my router and iPad, so one of them is misbehaving. This may be to do with how these have been implemented:
    http://en.wikipedia.org/wiki/Wake-on-LAN
    http://en.wikipedia.org/wiki/Sleep_Proxy_Service
    Either way I believe this is the source of the power drain issue whilst in standby with Wi-Fi turned on, perhaps this could be a router issue and that is why the issue not hitting everyone post 5.1.1?
    All the best.

  • Iphone 5 battery problem with iOS 7

    I am experiencing horrible battery time since I upgraded to iOS 7. I feel like I'm down to almost 60% of battery power. Anyone else experiencing battery power issues with their iPhone 5 and the new iOS?

    Strangely enough, the phone seem to have stabilized by itself, as if it had to learn my ways before getting back to normal. I did turn off some notifications, as well as some localizations, but that did not have any effect on my battery. After 2-3 recharges though it's now back to normal.
    @razmee209, Thanks for your help.
