poor battery life AFTER updated to 6.1.2

I just updated to iOS 6.1.2, and now my battery life seems to be worse than before. As I am typing this, I have seen my battery % tick down 1%. There are no apps running.

Yes I am having same problem too. The iOS 6.1.2 is killing my battery. When I got my phone in October

2012 with iOS 6.0 my battery was the best on iPhone 5. My standby time was 2 days & 2 hours with usage

12-14 hours. Now with iOS 6.1.2 my iphone 5 standby time is 1 day & 3-4 hours and usage is 6-7 hours. Apple sort

Your updates out. It's about the quality not quantity.

I have no idea if it will help, but I was having same problem w/ my 4s... My battery was draining like crazy after the 6.1.2 update.... I was getting 2 hours on standby and it was dead after a full charge... So as suggested in another thread, I deleted my mail accts, did a hard reset (holding down sleep and home buttons), then fully charged my phone. After establishing that my phone was now in fact not draining power I've reset my email accts and I'm on 75% power now after having my phone unplugged all day - it's almost 3pm... My issue is fixed....

I have good news and bad news. The good news is that my phone stopped fast battery draining! The bad news, I don’t know how or why!?


In the previous days and after upgrading to iOS 6.1 and then 6.1.2, my battery was draining about 3% every hour on standby. I did many tests from restart, reset and restore to deleting and adding mail accounts and so on, none of them worked.


Last night I left my phone on the table with 87% of charge. Next morning I was expecting less than 60% of battery, but it was on 84% after more than 8 hours!


To me, it is back to normal and I really don’t know how. I absolutely did nothing special. I hope this happens sooner or later to others with battery drain issue.

The battery drain issue started when I updated my iphone 4 to the IOS 6.1.2.
The battery will go from 100% to 0% in about 3 hours !!!
I called Apple support and they told me that they are not aware of an issue affecting the battery with the latest update. They did a diagnostic test on my iphone and found that my battery is healthy. Then then recommended that I backup my iphone, restore the factory settings and recover after that. In other words, delete everything off my iphone and reinstall everything all over again. I waisted a couple of hours doing that and .....I still have the issue of the battery drain.
I finally discovered the problem, and thus the solution!
To solve this issue, do the following:

Settings ---> Mail, Contacts, Calendars --->Fetch New Data ---> Advanced


Now click on your hotmail account or your company email account (anything in that folder other than yahoo, gmail or aol),

Change the setting from Push to Fetch !!!


And Viola ! Problem will be solved !


The problem seems to be that the mail exchange (i.e. microsoft, hotmail...etc) keeps checking and pushing emails from the exchange server every second (continiousely) and this is causing the battery to drain.When you change the setting to Fetch, then emails will start downloading every 15 min; but at least your battery will hold charge as it is supposed to do, until Apple comes up with 6.1.3 that hopefully will fix this issue.


Good luck. Hope this works out for you folks hence it sure did work for me this morning and it sure feels great.

Cheers !

Same problem. My iPhone 4s, my wife's iPhone 5 and our 2 iPad2 drain more battery than usual after updating to 6.1.2

The update description is kinda confusing as well, idk maybe i just don't get it. saying that they going to fix on the increase network activity AND decreasing battery life. I was wondering if they're going to fix the bug for our device to increase battery life, decrease the activity for our battery to last long or for our battery to drain more? Hmm.. Apple, Please fix the issue.

While push e-mail isn't supposed to cause problems, iPhones and iPads, including those running iOS 6.1.2, can begin checking in with push e-mail servers continuously after someone accepts a calendar update, particularly a change to one instance of a recurring meeting. This potentially drives up 3G/4G network use while draining your battery quickly. We had one iPhone 5 running iOS 6.1.2 check in with our Exchange server 69,878 times in one day. The solution was to turn calendar sync off and back on. We need to ask people to stop accepting calendar updates on their iPhones.

probably this is the solution (in https://discussions.apple.com/thread/4823372?answerId=21372449022#21372449022):


"To solve this issue, do the following:

And Voila ! Problem will be solved !"
