iOS 6.1.3 battery drainage

My iPhone battery was also draining at incredible speeds after updating to 6.1.3..... (completely dead in about 4-1/2 hours). Like most people I tried several things, each in succession to no avail....until I read about "Push". Thank you so much for posting! It WAS a very simple fix, and worked IMMEDIATELY. Afterwards, my phone held a charge at 100 percent for the rest of the day...and now the next morning the charge is still at an incredible 96 percent! Like you I would urge people to try this before going to drastic measures.

There is a great step-by-step article on exactly how to fix this:

http://ios.wonderhowto.com/how-to/fix-battery-draining-issue-your-iphone-after-u pdating-ios-6-1-3-0145493/

If the link is gone when you read this, here are the steps:

Disable Push Email

Having your iPhone constantly check for new emails is stressful on your battery. Instead of having your phone check for emails constantly, disable Push email.

To do this:

• Go to Settings -> Main, Contacts, Calendars -> Fetch New Data.
• Set Push to OFF.
• Click on Advanced and set each email account to Fetch or Manually (as opposed to Push).

ditto. iphone5 + corporate exchange + AT&T. prior to 6.1.3 i could go 16-24 hours easily on a charge. Now I can only go about 8-10 hours. This is aweful. Down 40% in 4 hours and it has been in my pocket all morning without use.

I have cycled my phone several times hoping an app was causing it and verified all apps/tasks were closed. Going on my thrid day of drain....

Go into Settings/Mail,Contacts,Calendar, tap on the Exchange account and turn off all of the switches. Reboot the phone by holding HOME and SLEEP until an Apple appears. Then go back to Settings and turn the switches back on. Wait an hour for mail, contacts, calendar to sync, then check the battery again. It will probably be OK.

Just to add to my earlier comment, it does seem to be exchange causing this issue, i followed Laurence Fitch message and now seems to be ok, everything was off anyway but after deleting the exchange accounts and rebooting i have now lasted 1 hour with 1% drop...seems to fix it for me and a few others at least, it also seems to have fixed my slow 3g speed also...

Thanks to Laurence

Mail isn't the only app that can get stuck, but it is a common one. Look at other apps that use a lot of data, such as Facebook. First try killing all of the apps in the Quick Launch ribbon, then reboot the phone.

If it still gets hot run the battery all the way down until the phone shuts off, then charge for 4 hours with the wall charger.

There are other issues also that cause your symptoms, but these are the most common.

I can confirm mine is now fine.

Go to settings

Mail, contacts, calendars

Go into iCloud and turn all switches to OFF one by one make sure you save all to iPhone though not just delete

Then go to each other mail account and repeat this procedure again making sure you select keep on iPhone not the delete option

Once they're all turned to off check your calendar to see if everything is missing off it and then you need to do a hard reset by holding the home button and the on/off button until the phone turns itself off.

Once it's come back on go back into settings and mail and turn each switch (or each you want) back to ON.

Then make sure all your apps are closed lock the phone and leave it for 30 mins and then check the battery hopefully if like mine it shouldn't of dropped at all

This worked for me hopefully it will work for others out there

Nice try, nut wat of there is no Exchange account?

That is answered further along in the thread (my post was specifically to someone who has an Exchange account), but the principle is the same. Find the app that is draining the battery because it is stuck in a loop. For mail, it can be any email account that supports Push (iCloud, Yahoo, gmail, AOL, Hotmail). If you have ANY of these turn them off and reboot, then turn them back on. After that look for other apps that can be using data and stuck. Facebook is a common one, so start with that (just kill it in the Quick Launch ribbon).

I have a 4S on Verizon and immediately after upgrade to 6.1.3 I started experiencing the rapid battery drain. Nothing else changed on my phone so I do completely attribute this to the 6.1.3 update. I went from a battery life at least 1 day to less than 6 hours of battery life overnight. This went on until I found this and other threads.

I did not have iCloud running but decided to delete that account since I wasnt using it and saw commentary about in other threads. I deleted my exchange account and did the power cycle of the device then added the account back in. I also turned off the auto-push and now only do manual checks.

My battery consumption now seems to be back to normal.

Thanks for the suggestions. I hope the rest of you find a solution that works as well.

One solution is worked on an iPhone 4S and a 5:

1. Closing every running app with multitask.

2. Reseting network settings: Settings - General - Reset - Reset Network Settings

3. Make a Force Restart (holding home + stand by buttons)

4. Wait until the device fully boot in.

Results (4S):

- Wifi on, 3G on

- Email syncing within 30 minutes

- Two games, facebook, music running backround

from 1pm to 3pm with no pushing the phone, battery decreased by 3%: 50% to 47%.

And I'm also suggesting if you want to update software, You should update ONLY via iTunes, after you closed every running app and turn off network connections.

Hope works.

I have an Iphone 5, a few day's after I updated to 6.1.3. The phone was getting hot and the battery drained fast. Tried everything I found in forums, nothing helped. I could see that the cellular data usage was going hard, what caused the drainage. I removed the iCloud account, which seems to do the trick. Turning everything off in the iCloud account, did not work (still fast drainage and continuous cellular data usage).

For now, I use it without the iCloud account set. I am verry disapointed that the bug seems to be in Apple's own software.

Have to disagree, The restores via iTunes have helped countless people experiencing issues, as does the setting>reset>reset all settings and allow battery to drain totally then charge for 3.5 hrs or more. Lawerence is correct that this is an ongoing issue for a handful (in the grand scheme of devices sold) of people. Typically its the update process itself not the iOS version. There have been a few versions with known issues but 99% of the time its an app or setting that hangs during the upgrade process itself. Best solution is close all apps,reboot, then perform an update of iOS. However the processes outlined in this and several forums are known to resolve these problems for a LOT of people. So you are incorrect with your statements.

Also, no one here is suggesting to turn off all apps and settings etc. The places that is mentioned is solely for troublshooting purposes. If the devices does not work in "out of box" state then probably a device issue. If it does work ok in that state then you have an app or setting issue. Apple most likely will never fix this because its a side effect of updating. I suppose they could add a routine to kill all apps and reboot and before updating, Anyway for the record I have no issues with 6.1.3. either so iOS itself works fine for me.

I don't appreciate you calling me a troll. Second, you useless fixes don't work...lol you may fool some of these people but not me. Your wasting people's time with your ideas as a temp fix. That makes me upset. This is an Apple problem. Let apple fix it. If that's at all possible?

But no reason for you to name call. I'm just pointing out facts. If I feel like giving my opinion on a company I stood behind for many years ill do so. And if no one likes it...tuff! I think these people with problems should be upset. Ipad mini, 10 hours of usage, I don't get even close to ten hours. No 3d games, no mail set up, iCloud off, location off, Bluetooth off, apps all closed in back round. A couple text messages and some Internet, 6 hours its dead! Wifi turned off when not using it, drains just sitting on my coffee table.

Don't waste your time with these wannabe fixes...call Apple or go in the store if you have one in your area. Thank you for giving up feeding trolls because your ideas or silly steps you've posted DO NOT WORK!

Yep again the update process itself creates these issues THATS what Apple needs to fix. Been around for a long time. The best way to update, close all apps from recents bar, reboot the device, then update via iTunes. It seems that if folks have stuff running then start an update it goes all to H***. Maybe OTA with a poor connection to wifi or who knows but its common and has been around a long time. That is why reset all settings or reset network settings help a lot of users after an update. Same as the deal you posted sorta, iCloud hangs up in a sync condition and never stops and causes heating up battery and draining it like crazy. Email same deal. At least 1 item in iCloud is the Safari bookmarks sync. Have seen a lot of reports of that guy getting hung and causing excessive drain. Glad that resolved your issue and thanks for posting it.

Good Morning

I had the same problem with 6.1.3 on a 4s but solved it:

I simply replaced the "old" IOS 6.1.3 which i've installed wireless with a new one via iTunes BUT:

I've used a "fresh" mac who does not "know" this iphone - so iTunes has never been conneted to my phone before. then i set up a complete new iphone and did NO install with any backup - all new: WORKS!!

old:

100% at 11 pm -> 40% at 7 am (no use between)

new:

94% at 11pm -> 88% at 7am

hope that works for you!

In settings try turning off: Facetime then reset phone and iCloud Documents and data and reset again. That worked for me, they were both turned on by the 6.1.3 update.

Since it sounds like you were not aware of the basic method of closing your open apps by double clicking the home button, you might want to read Apples guidelines to maximize battery life. It gives a lot of basic tips on what you can shut off to improve battery life:

http://www.apple.com/batteries/iphone.html

Hi! People in these forums are trying to help each other, so it would be best if we show respect to each other. There are no Apple people here, because this is a user forum. If you want to complain to Apple, go to the store or send them an e-mail.

Now, for the problem at hand... Nobody knows why this happens with almost every update, and we don't know how to safely update the ios w/o getting these problems. The important thing now is to solve it. Here is what I did:

1. Go to Settings>Mail, Contacts, Calendars>iCloud

2. Turn off everything from mail to find my iPhone, but do not delete anything. Leave everything in your phone or iPad.

3. Follow the same proceedure for every mail account you have.

4. Go to Fetch New Data, turn off Push, and check Manual. Go to Advanced at the bottom, and swtich everything to Manual.

5. Set Brightness to Auto

6. Kill all open apps. Reset the phone by holding both Power and Home buttons at the same time until the Apple logo appears.

7. Go back to Settings and turn your settings back on except for Push.

You will still experience some drain as the phone will try to sync everything back. If it still persists, then run the battery down until the phone turns off and charge it for four hours at least.

For me, I have Wifi on, bluetooth and mobile data off. I only turn on mobile data when I need it.

There are other fixes like Resetting all Settings, but this is the simplest and it usually works. You may have to do it a couple of times though. Just try it.

Thanks kulas...will try to find your idea too. But so far Stopping that Automatic Mail fetch under ADVANCED works fine for me.

NOTE: It is NOT the PUSH but the

Settings>Mail,Contacts,Calendars> Fetch New Data (which sb OFF)>Push sb OFF..then go down to Fetch set to Manually... Then go to ADVANCED>iCloud and set that Manual

You have to have each one set this way to keep your phone calmed down.
