You have an app that is driving data to your phone, causing the wifi chip to wake the phone all the time. Apparently a system app - a lot of people have been having this issue with KK6.

Beyond this - sorry, but if you are not rooted you will have to live with it. Identifying what is triggering the wifi interrupts requires obtaining a Wireshark capture, this is not possible without root. Even if a common root cause is found for what's going on with KK6, it's most likely in /system itself so can't be fixed without a custom ROM or at least rooting.

If you're not willing to root, why are you on a firmware developer forum? Have AT&T help you instead if you're on 100% bone stock unrooted.

Well if it's an APP causing it, then many many people must be running the same app cause all of the various forums out there are a lot of people with the battery drain after updating to 2.3.6. Even a lot of my customers have mentioned it also.

I doubt it is an APP doing it. I'd bet it is just some bad coding on Samsung's part. They are probably getting a lot of complaints and are most likely already looking into it.

As far as the why he is here if he doesn't root. Well I don't root as well and have no desire to being as stock works just great. (other than the battery drain)

This is a great place to hang out and keep up on other people using various phones. He posted in the General section, not the Developer's section for this phone. So I think his/her question was valid.

If he was asking the question in the Developers section I would understand your concern. But I don't feel you have to be into cooked ROMS to value this forum.

That's like saying to the people who like the "Fast and the Furious" moves to stop watching them because they have a Chevy and not a pimped up Civic.

I'm not rooted with wifi on all the time just got the phone 3 days ago and I'm getting 14-15hrs with no issue down to about 15-20% battery life left before I have to stick back on charger. Could be a bad battery or device, I'm coming over from Sprint after using rooted evo3d and rooted photon.

The forum is called xda-DEVELOPERS.com

If you don't want to root, you're probably better off in the AT&T support forums, because honestly, it isn't worth our time to try and help someone who doesn't want to root fix a problem that is almost sure to require root access to fix, or in this case, even diagnose.

I do believe many are having this issue after upgrading to kk6 (with same apps installed). I had the issue as well.

May be a system app, or something in /system causing an app to become unhappy.

Either way, it's not going to get fixed without Shark for Root captures from those encountering problems.

I don't think it anything to do with KK6. As Entropy said its an app causing a wake lock. I'm run Ingram KK6 without any issues with battery.

Having this issue as well. Phone is stock. Ive been here since the captivate but I hang around with the sgs2. Never needed to root this phone as it works perfectly for me. But I did the update this morning at 100% charge and 9 hours later with no use it's down to 9%. I could go all day with moderate use and be at 30-40% by the time I go to bed.

I read on a rather long on a google forum that many had this issue after upgrading via ota but who knows. I found that wiping dalvik and flashing unnamed update again I have much better batter life. I did read in update that he reverted to an earlier kernel signature to fix the battery drain.
