I was a little more excited after I got to know from developers that iOS 6.1 shows real improvement in battery life. And for this reason I downloaded the update within first 30mins after it was made public. The initial few hours were OK but then my battery started draining like anything.
I charged my 4S overnight , removed the charging at 6:30 in the morning( I know the time because its my alarm time). When I finally got ready, I checked the battery percentage >>> 87% <<<< !!!!! Without even touching the phone
I went to usage ( General - > Usage ) , it showed Standby and usage time same 1hour 37mins. So statistics and the battery percentage was in coherence. But which process used my phone for those 1hour 37mins.
After reading so many issues about exchange , I thought may be its my exchange calendar. I turned it off, but it brought no change in the statistics. With each minute , percentage was dropping down and counters for usage and standby were increasing simultaneously .
A technical and figitive guy like me can't really concentrate even on my breakfast when something like this is happening to my phone. I tried to figure out what else can be the culprit, just went through some points/features which were updated by iOS6.1 in my mind.
I had "Limit AdTracking" ON and tried to switch it OFF and observed my phone for sometime. And guess what ...
The battery percentage stopped decreasing, stand by time started increasing as compared to usage.I switched my exchange calendar back with push selected. And after loosing 30% battery in the first hour of the day, I came back home with 40% .I felt like a winner !!
This 40% was when I had 3G off, push working, telephonic calls of around 1hour-2hours, a bit of social networking & iMessage.
I felt really happy with each minute passed without a drop in the battery percentage ! I think many of us here in the forum can understand, how it would have felt.
I am not really sure, if this will help others as well. Each device is different, each person has its own variety of way of using it. And no Software is perfect, a developer CANNOT make code which is 100% bug free. It is just a matter of fact, how many use cases one has covered while coding your OS.
Just felt like sharing this experience and found it relevant , so jotted it down here. Incase it helped anyone, will be good to know.
All the best...

Im sorta suprised that has any or much effect. With it off they you can be targeted with specific ads based on your usage rather than just random ads. So I would think having it off would be worst. But not sure it really makes a lot od difference either way. However kay.kays indicates that fixed it for him so may be worth a shot. I would be more inclined to say the exchange issue caused it and switching off the calendar fixed it. The usage and standby times being the same is indicative of the exchange bug. Removing the email account,rebooting and readdiing it. OR sometimes just disable it and reboot then turn back on will solve it.

As mentioned in my post, I also assumed it to be exchange bug like sbailey4 mentioned. The story mentioned in the post is after I have miserably failed by trying all tricks related to exchange account.
What I also noticed that, i tried to click on "Reset Advertisement identifier ", an entry was logged into "Diagonstic and Data" . As I mentioned before, there can be so many usecases which might be there when handling with a device like iPhone. So may be it worked somehow for me, it might not work for all.
I have my exchagne account back to normal with everything ON except reminders and battery stats are which were shared were exchange account ON.

I own an Ipod Touch 4th generation. I updated to IOS 6.0.1 on Wednesday, January 30th,2013.
Is this bad... I charged my Ipod Today at 3:00PM ET (Well, it finished charging at 3:00PM ET), and then now its 5:20PM ET, and the battery is at 70%?
Is that bad?

I agree. I updated yesterday afternoon. My phone quickly ran out of battery and died. I fully charged it last night at 7pm and it was dead by morning, and I had closed all my apps before bed. Fully charged it again this morning and it was dead by 2:30. My battery was perfect before the update. What's the deal?

Did you happen to read my posts with some possible remedies? Just charging the device wont solve it. The steps I outlined in the 1-5 are a series of steps not try one then the other. Also look at the info regarding exchange email. Those are easy steps and are relatively easy and fast to complete (other than the discharge and charge piece) Failing those a restore would be a good next step and DFU restore as a last option. Both of those take a little more effort but are not prohibitive and certainly worth trying if you are getting poor results currently.

I had 6.0.1, and with the exception of exchange email push causing battery drain, my battery is fine.....in 6.1, it's also fine.....
I don't think it's the battery, I don't think it's the iOS......I think it's one of your apps causing something to be constantly running or even more likely, it is a process that's part of the iOS that's associated with a 3rd party (like the exchange email within the email tool.
even if you think you are shutting everything off, I sincerely doubt you are......dig deeper

Yes I did all your steps last night.. Except for step 5 leaving it on the charger for 1.5 hours. Your suggestion was the first I saw and thought it seemed reasonable. I can try to do it again but I'm not sure if this will work a 2nd time. Do you think I should try again?
Currently Being ModeratedFeb 1, 2013 5:34 PM (in response to Slamuel)
No if you did steps 1-5 in order and it made no difference. Although I have heard before folks doing it twice. Did you get the option to set up as new? Also the discharge/charge is pretty important. That is 1.5 hrs AFTER it says 100% not just 1.5 hours. There are 3 steps to charging the iP battery: fas (high current) ,continuous (drops down as a slow charge) , trickle (very low current to finish it off). The meter will report 100% before its completly charged.
Anyway follow that as written. If no help look to restore via iTunes as a next step. And dont restore your backup. That could put the problem right back in. Test it and see how it works.

Don't EVER restore your back up after restoring to 6.1!!! My 4s is running smoothly since then. 1 day 1 hour standby time with42% remaining. Minimal browsing, several calls and messages, location services on and data on (needed for find my iphone) 3g off of course.
