Have iPhone 6 and have 8.1 now w/battery drain issues. Advised to reinstall 8.1 in iTunes. How???

I seemed to have much better batter life on my iPhone 6 while on 8.0.2. Upgraded to 8.1 and now having battery drain issues!! Installed over the air on wifi and all seemed to upgrade fine. I've read a fix may be to reinstall on iTunes. How do I now reinstall 8.1 on iTunes when I'm already running 8.1? Any suggestions?

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

Iphone 4s IOS 7.0.4 update battery drain issues

I hope this gets to apple in regards to the issue of the battery drain. I have been following several discussions for the past couple of weeks and everyone seems to have some type of idea on what the problem is. I'm not a service tech or gadget know all, but I have been performing several "Nonscientific" test to see what is draining my battery.
I have a 4s that has always had good battery life. It seemed to run consistent to what was detailed in the product specs. I would only need to charge it every other day on limited use or the next day with heavy use. After updating to the latest update (IOS 7.0.4), the battery would drain in less than a day on limited use which is a couple of text, couple of email checks, 3 to 4 phone calls at less than 10 minutes each - no internet searches or game play.
So, after reading everyones suggestions in the forums and trying them, the battery still drained just as fast, if not faster. I read a post somewhere regarding “Bluetooth” constantly searching. So, I saw mine was doing the same. Someone replied to that person that it should not be the issue, as it does not use much power to run its task. (I found they were wrong)
Here is my nonscientific test, but a good one. (for the record I had nothing on in the notification center, Do not disturb off, only thing on in Privacy - location services was google maps, Siri, Yelp, and Find my phone; iCcloud was off; background app refreash was off; email fetch data was off; everything else was off)
Day 1 - I fully charged my phone several hours, I unplugged it at night before going to bed, did a hard reset to make sure every app was off, and only opened the settings app and made sure the Bluetooth was onand searching. I checked my phone 6 hours later and saw the battery drained from 100% to 56% with no usage other than just being on and in sleep mode. That would mean it drained at 7.3333 % an hour. Some would say that acceptable. - Its not when there is no usage. The battery would die in 13 hours with no usage.
Day 2 - I repeated the test (as above), but turned off the bluetooth. I checked my phone 6 hours later and saw the battery did not drain at all. I started with a 100% and battery was still at a 100% with no usage other than just being on and in sleep mode. I opened a couple of apps and closed them to prevent them from running in the back ground and noticed I lost about 2% of charge after usinging it checking an app or 2. I put it back to sleep mode and checked it again in an hour and saw it only drained 3% down to 97%. Very acceptible.
Day 3 - I repeated the test, but during regular day hours with limited use of the phone (with bluetooth off). I was back to getting close to a normal battery drain I was experiencing prior to the update. I know that IOS 7.0.4 uses a little more battery power to run as it has different features and abilities, so the battery drain was not like it was before, but a lot better.
So, my experiment concluded to me that the new update is causing the bluetooth searching to run in the back ground continuously and causing the battery to drain unacceptably fast on my phone. This is a program issue that can be fixed by Apple. I find it unacceptable to have to control my bluetooth manually, as I never had to do it before and I shouldn't have to do it now. I hope Apple will fix it soon. I‘ve been a apple product person for years, and enjoy the products, but lately they have been not been satisfactory in the phone business. I have been playing with a samsung galaxy thats looking very promising, if apple doesn’t fix the issue everyone is having, they will loose business to competitors.
Please fix the issue!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......
Hopefully this will be useful to others in this thread ..........

Traded in my iPhone for a different brand of phone. I had no idea that I had to sign out of iMessage before doing this. Now, my old phone is gone and my new phone cannot receive texts from people who have iphones and had me as a contact before. They try to send an iMessage and I have no way to receive an iMessgae now. On some server somwhere my AppleID still tells people they should send me iMessages. What is the solution to this issue? Deleting my AppleID would work to solve this issue, but I cannot ever delete the ID? What can Apple do for this?

If you did not erase your apps and data before getting rid of your old phone, try using Find My Phone and erasing everything remotely. See if this works.

What do you mean? Your only way to unlock that phone is to have had 40 days continuous service with T-Mobile and then process the unlock through them. If you had an account with T-Mobile you should be able to login and process your unlock. If you did not you can click on the chat program but they are going to tell you the same thing.

I've broken my iPhone and have put my sim card in my old iPhone 3. If I plug my old iPhone 3 into my computer, will it update the iPhone 3 with everything that is on my phone that is now broken, or will it 'update' iTunes with what was on the old iPhone?

Plug your phone into the wall charger for at least 30 minutes...make sure you have a sim card in the phone...then:
Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new.
Make sure you have no anti-virus software running or any firewalls...turn all of that stuff off.

My husband and I both have iphones and share the same apple id. Everything was working fine until I synced his phone which lost all his contacts and pictures and gave him my info. I then used verizon's contact retreival app and got his contacts back

My husband and I both have iphones and everything was ok until I synced his phone and lost all his contacts and pixs. I downloaded verizon's contact retreival app and got his contacts back but now his contacts keep overwriting mine. I can sync my phone and get my contacts back but within a few hours, his show up again. We use the same apple id for purchases. What can I do?

Are you sharing the same iCloud account (in Settings>iCloud)? And do you both have Contacts turned to On in Settings>iCloud?

I am using a very old iphone and have forgotten my password. Is there anyway to get passed the lockout screen?

I am using a very old iPhone and have forgotten my password. Is there anyway to get passed the lockout screen? It says to connect to iTunes but when I do nothing happens. I've read through the user guide and am at a loss.

Bypass & Reset the iPhone Passcode
Disconnect the USB cable from the iPhone, leave the other end connected to your Mac/PC
Launch iTunes
Press and hold the Home and Power button on the top of the iPhone to turn off the device
Press and continue to hold the Home button while you reconnect the USB cable to your iPhone, this will cause the iPhone to turn on
Continue to hold the Home button until an alert message in iTunes appears that an iPhone in recovery mode has been detected
Now that the iPhone is in recovery mode, you must restore the device:
From iTunes, look under the “Summary” tab
Click on the “Restore” button within iTunes

You need to reconfigure your phone for use with your Apple ID. I suggest you restore yours as new then reconfigure it with your information and Apple ID. Be sure to disable Find My Phone, if it's enabled, before proceeding.
Locked Out, Forgot Lock or Restrictions Passcode, or Need to Restore Your Device: Several Alternative Solutions

4. What to Do If You've Forgotten Your iPhone's Passcode
5. iOS- Understanding passcodes
6. iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
7. iOS - Unable to update or restore
Forgotten Restrictions Passcode Help
iPad,iPod,iPod Touch Recovery Mode
You will need to restore your device as New to remove a Restrictions passcode. Go through the normal process to restore your device, but when you see the options to restore as New or from a backup, be sure to choose New.
You can restore from a backup if you have one from BEFORE you set the restrictions passcode.
Also, see iTunes- Restoring iOS software.

I have a 3G iPhone and have changed my email which I use an an ID. it is changed on my iTunes (PC) but the old email/ID still appears on my 3G iPhone so I cannot update my Apps..........how do I get the iPhone to accept the new ID??

I have a 3G iPhone and have changed my email and Apple ID on my laptop/iTunes account.
How do I get this new ID to show on my 3G iPhone.
I still have the old ID and cannot update my Apps.
PLEASE HELP !!
thanks, Nosuh

Did you purchase or download the apps with your old ID? Apps are tied to the ID that is was purchased from.
If it is a new app you bought with your new ID, you can go into settings - appstore- apple id and then log out.

How can I remove my company's iCloud Contacts account from a former employee's iPhone and have the current information removed as well?

How can I remove my company’s iCloud Contacts account from a former employee's iPhone and have the current information removed from their iPhone at the same time as well? Will just changing the iCloud password be enough? Our company shares an iCloud account for convenience but when someone leaves we don't want the information to stay on their iPhone.

Changing the password would only block them from accessing the iCloud information. They would still have access to the local copy on thier phone. To delete the local information, you would need to go to Settings>iCloud on the phone, tap Delete Account, then choose Delete from My iPhone. (This only deletes the iCloud account and data from the phone, not from iCloud.) This, obviously, must be done during the exit process as it requires access to the phone.
