iOS 6 iPhone 4s battery drain

Here is how I fixed mine.

1. Installed Google Chrome

2. Went to Settings > General > Restrictions > set security Key > Disabled Safari

3. Closed out of settings

4. Held down the top button and the center round button to hard shutdown the phone.

5. After phone restarted from hard shutdown my battery automatically restored

The problem is in safari... I also got a bill that showed massive amount of data useage.

My battery life is amazing after this.

This has worked on all my co-workers Iphones at work. Google chrome stinks as it does not fully integrate into ios6 but it gets the job done until apple gets it together and fixes this problem.

After following this community for the past several weeks, and trying everything that everyone had mentioned with no success, I finally took my iPhone 4s into the Apple store last night. I had pretty much turned everything off with the exception of my phone, email, and text messaging. I did leave "find my phone" turned on through the iCloud settings afer seeing a lot of posts about turning off everything else under iCloud, which did make a small difference. I was getting so frusrated with my phone since I normally got 16 hours of battery life prior to my upgrade to the new iOS 6 upgrade. I basically hated my phone. When I took it in to the Apple store, the guy wanted to verify that my battery was good, but was unable to verify since their network was down. I knew my battery was fine, since I had no issues until I upgraded. What he ended up doing was going into the Mail settings, went to fetch new data and turned off push, and set it to fetch my messages every 15 minutes. What he told me was that with the 3G on the new iOS 6 operating system, it was constanting going and getting data. That was one of the reasons my phone was hot all of the time. So today was a big test, I unplugged my phone early this morning, and this evening, I still have 68% of my battery life left. I hope this helps others. So make sure you turn push off, and only fetch your email. Good luck.

Ok,

Now I have Safari and all the related iCloud syncing disabled and the battery life is close to normal. 36 hours from the last recharge and still 40% left. This work around is Based on AlPrunty & Blunderact messages - Thank You!

Disable these two from "Settings"

- iCloud > Disable Safari

- General > Restrictions > set security Key > Disable Safari

After this I had a major improvement in battery life. But as I mentioned - this is only a work around! You need to install some other browser, you can't sync your bookmarks, ...

To improve it even more you may want to disable other iCloud features, mail fetching frequency, etc.

Just an update to my post.

With this work around I got 60 hours of "normal" usage. So, Safari+iCloud is the problem... At least for me.

Even though it's not as good as before iOS 6, I can live without Safari for a while :-)

I just hope the battery did not wear out too much during the weeks of massive drainage...

This was my problem, too. Specifically, my iPhone 4S battery was draining with push enabled on an Exchange account and only when cellular data was also enabled. My phone was also hot to touch. On wifi only, I had no battery drain problems and the phone was cool.

Disabling push for my Exchange account fixed the issue. I still have push enabled for iCloud and Hotmail.

I don't know whether this was triggered by a server-side change or something else, but this issue started at approximately the same time on my new iPad and on my iPhone 4S, both of which had recently been upgraded to IOS 6. I have the same Exchange account on both and on both the issue only happened with cellular data enabled.

Just an update: I tried everything (restoring from backup, restoring as new, OTA, through iTunes, with SIM, without SIM, with apps, without apps, airplane mode etc.) but nothing really helped, some actions just made the drainage slower.

Finally I went to the Apple Store and they replaced my phone (though - of course - claiming that there's nothing wrong with the battery and iOS6). Now I have 5.1.1 and all the problems are gone.

I had a terrible battery drain

Drooping 1% every minute

FIx ........ Backup all images tunes ect on iTunes to PC

Make sure to backup contacts

Do not backup APPS

In iTunes setup has new phone. Which wipes everything,

Then put back ure tunes contacts

You wil then have to reinstall apps. DO Not Restore apps from backup. Renown load from App Store

Once done..... Turn off notif........ iCloud. Ect

DO NOT install Facebook. Use web for that

Finally turn off phone restart and then reset network.

That's it.

My phone looses 1% on standby over 12 hrs dam brilliant. And that's with 3G data on

Caleb, if I turn off Safari and iCloud for Safari then restart my phone, the constant drain stops. I invested $0.99 in System Activity Monitor. It will give you clues as to what is keeping your CPU running at 100%.

I now use Chrome, have Mail and Contacts set at Manual, most location services and all notifications turned off. Blocked Safari use thru Settings/General/Restrictions. In the past, I've done other stuff but making sure Safari is not launched or synced with Safari on my iMac thru iCloud has helped the most.

Caleb, When you see the usage and standby staying the same that is a classic symptom that you need to perform the settings>general>reset>Reset All Settings and select set up as new when it reboots ( it wont erase your data or apps) or if you are using exchange email delete the account and reboot and see if issue stops. Then add back the account. Some app or your email or a setting has taken over causing no standby.

BTW do NOT choose "erase all content and settings" That will erase your apps and data. The reset all settings will not. And be sure to select "set up as new" when it reboots. You will only have to select your walpaper and wifi networks etc again. Any particular settings you changed (like turning off most of the junk in location- system settings)

Just another update to trying to figure out any way to slow the drain down so I can actually make it through a day with SOME usage of my phone. Gonna do a test tonight and see where we are at in the morning. Here is a screenshot of what my phone says has gone on since it was fully charged:

All I have done is listen to 25 min of a continuous podcast and sent 3 text messages in that time. Nothing else. But this still shows up. Anyways, I'm just going to let my phone sit overnight without charging and see how much it drops. Will post results in the morning at 6:30 am when I'm up.

I think I may have found a solution. Also, this is where Apple dropped the ball big time IMHO.

1. Disable Safari bookmark syncing in your iCloud preferences.

2. Switch off the Do Not Disturb-feature.

3. Reset the network settings by going to the Reset menu in the preferences pane.

I noticed a major increase in battery life since I disabled these two "features" and made a reset, both on an iPhone 3GS and an iPhone 4.

As far as the Safari bookmark syncing goes, I found a bug in this feature where the iPhone endlessly creates copies of my bookmark set every time I sync. This may cause the aforementioned battery drain. Let me know how you guys and gals manage.

At least for me, the battery drain culprit has been with Safari. Took several days after upgrading to iOS 6 to figure it out and playing with every setting the device has. The solution for me was to disable Safari in settings and use Google Chrome. Since doing this, my battery drain has been close to what it was under 5.1.1, but still not absolutely perfect. With Chrome, I can usually go the whole day--maybe a day and a half--with moderate usage, wheras under 5.1.1 I could easily get two days, sometimes even with heavy useage. Even with Chrome, there are still bizzare ups and downs in battery drain where the battery might stay at 100% for an hour or so of use, and at other times it will drop rapidly. The average over a month, however, is at least sorta close to 5.1.1. The only drawback to using Chrome is that some apps use Safari (or Safari code), and with it disabled these apps don't work fully. The National Weather Service app is an example of this--the app itself works, but if you click on a subpage (like the Hurricane section which is kinda important at the moment here on the east coast), it goes nowhere because it relies on underlying Safari code. Apple in late September installed the battery tracker program on my phone and exfilled the data a couple of days later, so I was hoping that they would at least publicly acknowledge there is a battery drain issue, but even the most recent news rumors of 6.0.1 being in test fail to mention ANYTHING about the battery issue. That has me very worried. As of this post, there have been 208,000 views of this page and more than 1300 posts---that should be a warning to Apple that THERE IS a problem and that the company should at least publicly acknowledge it.

Proved to myself once again that Safari is the primary culprit on my phone. Launched it and CPU usage went up to 100% and stayed there. Quite Safari and the usage stayed the same until I turned the phone off and back on again. CPU now near 5% again. Battery doing fine as long as Safari off and restricted. Still have Mail and Contacts on Manual rather than Push.

I would call apple at 800 275 2273 and explain what's going on and what you've tried.

I don't know if it was just timing, but an Apple Care senior advisor called me shortly after posting here, since I signed in with my Apple ID and had registered my phone and contact info. They let me know engineers review the official discussion forums in case there are trends, or lots of people with a particular issue I guess, andasked if I would install a battery logging profile and explained the info it would collect. He emailed me a certificate I installed and showed me where the logs get saved in my computer, and asked me to zip up and email him the text logs after a few days. It's been a couple weeks and I have not heard back, but he said the engineers probably need to address this in an update.

Fortunately or unfortunately, I let him know I feel my problem was more or less resolved, but I'd send any info that would help. After turning off all cloud stuff, deleting my iTunes login from the phone, cleaning up the bookmarks on my Mac and phone, letting the phone die, charging it to full and doing a power cycle (holding down power and home button until it reboots itself), my standby was way better than before and I only noticed fast power drains occasionally using Safari or streaming music, or reasonably normal usage. It could be better but I think my 4 is OK and fairly predictible now. iTunes U seems to be a background bandwidth and battery killer still I think, and I couldn't find out how to tell it "no cell data" like other apps.

If you're still having issues after trying the things people suggested, I really would just call Apple at 800 275 2273 and possibly fill out the feedback form at http://www.apple.com/feedback/iphone.html and let them know honestly whatever issues you've noticed associated with the update, if you've been following forums and what fixes you've tried, etc. My phone is 2 years old and they still seemed concerned with my issue. They also suggested resetting the phone as a new phone and I explained I hate redownloading and reauthorizing everything, especially all my Amazon books, and let them know mine's good enough now.

I had the problem with my ipad after updating to IOS 6 in september. Skipped the facebook integration and the Facebook app. And reinstalled from Itunes. I have 13 -15 hours usage now.

Since two weeks I bought myself an Iphone 5 with IOS 6. Installed it with Icloud. And a very fast batterydrain.And I saw that the Usage and Standby time stayed the same. So it was constantly processing, even it was in standby. Immeditely I reinstalled it with the cable and Itunes and skipped the facebook integration and the facebook app as well. I saw immediately that the usage time was not running anymore and I reach now nine hours usage, which I think it is quite normal.
