Let me state first of all that i have the iphone 4S

Since upgrading to iOS 6.1 and then 6.1.1, i've encountered heavy battery drain. Now i'm well aware of the reported issue causing the battery drain - supposedly this Exchange issue.

This raises a question itself... if you do not use Exchange emails would this still affect battery drain that i'm current experiencing?

I know it's early days yet but have any 4S owners noticed and improvement on battery life since upgrading to 6.1.2 and then JB'ing?

I'm using 6.1 iPhone 5 WITH Exchange and I haven't experienced battery drain issues myself.

The issue was only with the 4S i thought?

failing to realise that might have been my bad.

if you're not using Exchange, wont make any difference, since thats exactly what caused the massive battery drain.

Personally I am still on 6.1, never really updated, since I don't use Exchange, and since after Jailbreaking, my battery life has improved :)

P.S. I am using iPhone 5

weird, I have not experienced such problem as of you, and i hope i never do ^^;, nonetheless good luck finding a fix somehow, I don't want to recommend to you to go with the upgrading, and causing you more problems, so do what you think it'll be best ^^.

If it's not Exchange draining my battery (as not using it), then i'm puzzled as to what is causing the problem.

I did a fresh restore and JB at 6.1 without syncing to an old backup i.e. just starting from scratch and also did the same when upgrading to 6.1.1 as i thought the latest update would cure my battery problem. The problem still exists.

If upgrading to 6.1.2 isn't going to cure the problem, does anyone have any ideas as to what the problem might be?

I did notice the issue being resolved. I use Exchange and had to update to 6.1.2

I would lose 20% of my battery within 1 hour. Now I am at 95% for the same duration.

I am using iOS 6.1.2 jailbroken with evasi0n 1.4 on my iPhone 4s, I found a big improvement in battery life by turning off the 3g when I am on wifi in my home network. If you have both 3g or LTE with an iPhone 5 and wifi on try turning off 3g or LTE and see if your battery life changes.

Early days for me but i've seen an improvement on battery life now i've upgraded to 6.1.2.

Remains to be seen if the battery if life is going to reasonable once i put more apps on and install some cydia tweaks.

I have now restored to 6.1.2 (dfu), set iphone as new (no restore backup), jailbreak and install all apps and tweaks one by one (no xbackup) now the battery works nicely and no closing apps issue and works. cheers.

Well i thought battery life has improved but been dreadful today. Down to 35% in around 8 hours and hardly used it much.

Checked on the apple forums earlier and there seems to be quite a few complaining that 6.1.2 is even worse than 6.1 and 6.1.2

Well and truly stumped on this.

Wish i hadn't bothered upgrading from my 5.1 JB now.
