IPhone 6 Plus & iOS 8.1 Battery Drain...

Hey,
i have 6plus 64gb, and installed new 8.1 ios.
i noticed clearly that the battery drains so fast. (Like %33 reduction)
After take a look at another iphone user's forums, too many people complain about the battery.
submitted for your information.

In most cases the problems when switching to a new iOS version are (as I had with my switch from iOS6 > iOS7):
- rogue app process (app not updated yet to iOS8/8.1) check Settings > General > Usage > Battery usage in percentage to determine which app is using much more battery although you haven't used it at all or much.
- settings in e-mail receiving is changed
- background app refresh (turn it off if you do not need it)
- location services (look carefully which apps you want to use this feature)
- notifications (look carefully which apps you want to use this feature)
- Facebook app

  • IOS 4.1 battery drain understood

    So I went to the Apple Store locally today to have my iPhone 4 examined for the post iOS 4.1 battery drain and heat issue.
    It took about 90 seconds for them to identify an issue and replace my phone. Apparently the 4.1 update changes the modem software rev and actually creates a background process that is unnamed and never stops. It's a bug apparently.
    My iPhone 4 was one of the original 600,000 sold on day one. In fact, mine was delivered the day before the release. I am thinking the first phones might be more susceptible to this.
    So, the replacement is running 4.0.2 and the older modem FW rev and is absolutely wonderful again. No 4.1 until this issue is resolved.
    Point is, there is an actual issue with SOME of the phones, so don't let anyone tell you you're wrong and you shouldn't have to disable ANYTHING to use your phone normally.
    The guys at my local store were very helpful and interested in this issue.
    Anyway, if you're troubled by the battery drain, take your phone back and let them try to identify if yours is affected. After all, if we want the bugs fixed, we need to let them know and this forum really won't do that.

    Good on ya' then. I'm glad it's not widespread. However, it's also not a one-off. If it's a problem the Genius Bar knows about already, then a fix is obviously in the works. Just like with the touch of death, they're in damage control mode until they know how big it is.
    I'm so tempted to update the new phone, but it's just working so well on 4.0.2 that the idea of a repeat just terrifies me.

  • HT1766 Upgraded iPad 2 w/IOS 7. Battery drains to 0% even with iPad in sleep mode.  Called Apple-they had me clear it.  Battery charge held that night.  Restored from iCloud. Charge not holding again.  Any similar events?  What to do?

  • Will Apple fix the iOS 5.1 battery drain issue?

    People keep giving battery saving solutions to the iOS 5.1 battery drain problem but that is not the issue.  With iOS 5.0 battery life was terriable. Apple quickly fixed it with 5.01.  Now with 5.1 battery life is back to terrible.  I could go at least two days without a charge.  After the update (and all my patterns and behaviors being the same), I don't even get a full day!  Apple needs to fix this! Or allow us to go back to iOS 5.01.  Will Apple fix this and if so how soon can we expect a solution?

    Yes, you need to setup the phone as new.  I understand your issues on the whole process of setting everything from scratch, I'm afraid that's the only way out.  However, if you look closely, on the whole, it boils down to following issues only.
    Contacts - You will get this back once you setup your iCloud account on the phone so it shouldn't be a great issue.
    Apps - Do a transfer purchase to your mac/pc before going for firmware complete reset, once you set the phone as new, you can always sync back the apps. This beats the inapp things like game levels, or your pdf docs synced earlier.  iBooks can be restored, otherwise enable document and files backup to iCloud in settings before resetting the phone, then you can get everything back from iCloud.
    Mails - If you have a mac you can keep all your mail accounts configured on Mail.app, post install you can bring them back from Mail.app to phone easily; otherwise, I'm afraid you need to do everything manually
    Settings - you will have to setup your wifi configuration, VPN if any manually from the scratch
    Dispite all the hasseles listed above, the battery fix would be a hot sun on the face in a winter day.  Go for it!

  • IOS 7.1 battery drain iPhone 4S

    While the performance increase on iOS 7.1 appears genuine - I'm experiencing serious battery drain on my iPhone 4S (64GB model).
    I have parallax disabled as well as background app refresh disabled.
    I updated from iOS 7.06 to 7.1 via USB cable attached to my Mac Pro and the latest version of iTunes running on Mavericks latest version as well. I had closed all apps and done a reset before connecting to iTunes where I did a backup and sync prior to updating.
    The drain I'm experiencing is during usage, not standby as much. When I use my standard apps (mail, safari, txt, etc.) I'm seeing the battery drain about 1% per minute. I'm not using GPS or bluetooth.
    I followed one suggested on Apple Forums to drain battery to about 40%, then do another hard reset. Doesn't seem to help.
    Anyone know of similar issues or what to try next?
    Are there any tools available to see what apps might be running in the background that are causing the processor to drain the battery so fast?  And yes I am now closing all apps after using them to try anything to save battery.
    Very tempted to find a way to downgrade to 7.06...

    Thought I'd reply to this seen as no one else has, I am also experiencing very similar problems with my 4s and by the looks of it is it's across all handsets. I've never had any battery issues with my iPhone even 7.0.6 was fine, but since updating to 7.1 the battery is ticking down very fast. I fully charged in the morning and left it in my locker all day at work when I got my hands on it it's gone down to 52% just on its own!!
    I really hope they sort this out fast the irony is 7.1 was supposed to help battery life!

  • My iphone 4s doesn't work with iOs 8. Battery drains very fast!!

    After installing iOS 8  I'm starting to hate my smartphone. With iOS 7  the battery lasted until the evening while now barely reaches mid-afternoon with the same use of the phone and being careful not to leave apps in the background. I'm afraid to use the smartphone to save battery power ... frustrating!!
    I ask Apple to release as soon as possible an upgrade to fix all the problems with iphone 4s or enable us to return to iOS 7.

  • IOS 5 rapid battery drain (including in sleep mode), springboard crashes: FIX!

    OK folks, I resolved all issues in their entirety with the help of a genius bar tech who recognized that I was very technical.  WARNING!  Sync or backup your phone prior to performing these steps!
    First, do a MANUAL download here of the IOS 5 that matches the model of phone you have and save that image to your desktop or some other place on your computer.  PUT THE PHONE IN DFU MODE, not recovery mode (google on how to accomplish if you are not familiar).  The raeson why you are going to put in DFU mode is so that you will be able to not only get a good copy of IOS 5 installed but to ensure that your firmware is not corrupt, which appeared to be the case with my battery drains and springboard crash issues.
    One you are in DFU mode (your screen should be black the whole time, again google), open itunes and it will give you a warning that says that your phone needs to be restored.  If you are on a mac, hold down the option key and press RESTORE in iTunes.  This will open up a box that will allow you to "locate and select" a file, which will be the IOS 5 image that you manually downloaded before.
    Once you do, the iphone will start to restore.  After all of the restore cycles have been completed, you will be prompted in iTunes to either setup as a new phone or restore from backup.  I USED RESTORE FROM BACKUP so that I could preserve all of my settings.  Everything has been working PERFECTLY ever since completing these steps!  I will probably go ahead and make a separate thread related to this fix.
    I hope this helps!  Scott

    Their is another thread in here that mentions turning off reporting of Diagnostics data (Settings --> General --> About --> Scroll to the bottom/Diafnostics --> Select Don't send.
    Another item to check are you E-mail accounts. If you only have one account in this section then you should be good. If you have multiple and have every feature turned on (Contacts, Calendars, Reminders, etc) then your device could be trying to update to all and timing out which would get it to retry over and over again. I have turned off all the other features for my email accounts with the exception of iCloud and my battery life is looking good.

  • IPhone 4S 5.1.1 Battery drain, fixed for my case

    I just got a 4S, to replaced my missing iphone 4.
    The firware was 5.1, so I upgraded over the air (using the phone alone) to 5.1.1
    Then I restored by phone using the back up in iTune.
    But I realised my latest backup was in iCloud (I did not backup all apps in iCloud), so I restored with iCloud again, after goto Reset Settings two times.
    Starting to use the phone, experiencing very fast battery drain, 1% drop every 2-3 minutes.
    at one time I notice the battery was hot and battery drain real fast. I found the reason:
    the iCould continue to restore but stuck. Just goto Settings - iCould -Storage & Backup, at the bottom you see iCloud Restoring (or something) then phone..
    Just cancel or stop it. Because in my case, all the apss I needed already restored.
    Next day I still experiencing very fast battery drain, 1% drop every 2-3 minutes. I tried all the Location Service - System Services - Setting Time Zone (it is on all time (purple)), but actually its not the culpit, my friends has this on and all the time has a purple arrow, no battery drain issue.
    Also tried removing email accounts, in my case, it still does not resolve it.
    I decided to have a clean upgrade to 5.1.1 (over 890MB) instead of the phone over the air upgrade (50MB+), so I connect the iphone 4S to iTune , has it synced and backup.
    Click the restore, and iTune download from apple and wipe/upgrade to 5.1.1 again. Restore it from itune after that (not set as NEW phone),
    TA TA!!
    All the problem gone.
    Hope this help, if you have similar case like me.

    It is me again, just to explain that the thing that sems to lock up the computer in step 7 of 7 is "Syncing GEnious Data to iPHone". I don't know if that helps,  but any thoughts appreciated.

  • I have just got my new iPhone 4 white and the battery drains quicker than it should. How would I fix this?

    I got my new iphone 4 white 32GB today and the battery drains quicker than it should

    So based on that you're saying around 6 hours discharge? That sounds about right if you're on the web using 3G. Games and apps eat up the battery faster.
    Talk time:
    Up to 7 hours on 3G
    Up to 14 hours on 2G (GSM model only)
    Standby time: Up to 300 hours
    Internet use:
    Up to 6 hours on 3G
    Up to 10 hours on Wi-Fi
    Video playback: Up to 10 hours
    Audio playback: Up to 40 hours
    Knowing what you were using it for would help

  • Iphone 3GS 3.1.2 Battery drain problem

    Hi,
    Recently i have purchased Iphone 3gs with software 3.1.2. I'm facing a serious problem of battery drain. Without doing anything, the battery drains so fast. Is there is any way to over come this problem?

    Here's what I do that usually keeps battery life accurate. Drain the battery till it's dead, charge up full and do a hard reset while it's still plugged in and it usually works. If this fixes it just keep killing the battery and charging it full. If it acts up repeat steps above. Mine works almost everytime when it starts acting up. I was just trying things and this worked. Hope this helps

  • Iphone 4 from sprint and battery drain issues

    how many people out there bought a new iphone 4 from sprint and having the rapid battery drain issues?  there is a big thread on the 4s but not as much on the 4 and im trying to decide if its best to just exchange it or try more fixes.

    I have the same issue. I am with sprint. The battery goes down in 6 hours, mostly in standby and some emails. I can actualy see the battery meter going down every 30 sec when reading my mails. iCloud is disabled as also push notification. The phone gets also hot. This issue is completely stupid and remember, I had iPhones for the last 3 years. My last one was the 4. It is first time I have such a problem. My friends that have the 4S with AT&T do not have that problem. As a mater of fact, I compared today and mine goes down 50% faster. I will have to return it and switch to another provider.

  • Plugged in my new iPhone to charge before letting battery drain to 0%. Did I ruin it?

    I plugged in my new iPhone 6 to charge before letting the battery drain to 0%. It was at about 86% when I plugged it in to my computer to restore everything from my previous phone and then left it to charge to 100%. Will my battery be ruined because of my failure to let it drain before charging it? Pls help!!

    You aren't supposed to let it drain fully before charging it - in fact, repeatedly doing so can damage the battery.
    Charge it whenever it is convenient for you. Try to avoid running it all the way out unless necessary.
    Apple does recommend running it out about once per month, and you can also run it to 0% if the battery gauge seems to be incorrect.

  • IPhone 5S Getting Heated and Battery Drain issue

    From Past 2 Days , my iPhone is been getting heated and the battery drain is 1% per minute.
    Earlier When i used to put it on standby it used to be only a drop by 1-2 % through out night. Now it has gone down to -35% to 40% drain.
    I have tried
    -Resetting all settings
    - Restoring to fresh new iPhone
    -let my battery down to 0 and then charge it to 100% again
    But Nothing Helped, i am out of the country for work and i visit an apple store here.
    Any Suggestions, How do i Fix it?

    I have a VERY similar issue to extremecoder...
    Iphone 5s 16gb (purchased from Apple Online U.K. on 8th December 2013) was fine until the last two days onwards. I am now getting incredibly quick battery drain. The image is a screenshot taken this morning. Phone was charged to 100% last night and used for an hour or so, with battery level on 50%. I then switched off overnight as I always do.
    Turned it back on again this morning and was at 48%!
    Now look at it.    Do I have a case here for a replacement phone?
    P.S. Location services, bluetooth etc all off as they always are. Nothing has changed at all in my usage habits with the phone.
