Im going back to 2.3.4 via this method.
http://galaxys2root.com/att-galaxy-s...y-s2-sgh-i777/

Losing 10% of my battery at idle /hour is ridiculous lol. Android os was at 87+% within 3 hours of restart.

Edit:
Okay so I did this method. Took about 5 mins after I got everything downloaded. I did not do the factory reset since it's not needed. Phones back to 2.3.4 and nothing was reset. Have all my sms's contacts, aps, wallpapers etc. Battery seems to be back to normal.
I recommend everyone who did that 2.3.6 update to revert back. To many problems with it.

I never entered download mode on this phone before. Just a tip: Keep holding all the buttons till the phone seems like it shuts off and keep holding them till you get into download mode. Do not let go or else it just powers off.

For the purposes of attempting to fix the problem, I really would like some people to take some Shark for Root captures as described in my Known Battery Drainers thread.

With that data, the root cause of the problem might be identifiable.

So far I've only seen one capture, I really need more unless I can reproduce the problem myself.

I'm also having battery issues but would like to try to fix it before giving up.

I've searched a bunch but can't find that thread. Not at home to try it on my PC so if you'll link it here, I'll do what I can to get some captures for you.

I read a possible solution on another forum and tried it with my SGS2 today and am amazed at the difference today in my battery life.

Worth a shot as it does not require anything more than charging your phone and pulling the battery.

Charge your phone to 100% with the phone off (hold the power button for 3 seconds or so until the menu comes up and select power off). When you reach 100%, unplug the charger and remove your battery (some said keep the battery removed for 90 seconds while others said 3-5 minutes). I left my battery out for 5 minutes or so. Put the battery back in and power on.

That was it. My Android OS went back to normal and the battery life today has been great if not better then with 2.3.6 than before I updated.

Screen grab of my current battery use after trying this method this morning is attached.

Placebo effect - did nothing a plain old reboot would not have done.

Quite possible, but still running on the same charge from this morning and am at 28% battery after 14+ hours of normal use which is all I expect (calls, texts and light web browsing during the day over data) and then couple hours of web use at night over Wi-Fi when at home.

The last few days I was charging the phone when I got home from the office if I wanted to use it at night. Android OS was way up in the 60+ range after I first updated OTA and today it has been under 20% and more near 15%, so I'll take it.

Come to think, I probably did not do a reboot after the update and could have been all that was needed.

I did this and saw absolutely no change. 2.3.6 is draining my battery far faster than 2.3.4 ever did. The culprit is the Android OS running at 90%.

I read that it might be an issue with the wifi so I have turned that off and will report back if that seems to fix it.

I read on another forum that att and Samsung are trying to blame it on bad batteries and shipping out new batteries.

What a bunch of crap. People everywhere wouldn't suddenly all have bad batteries at the same time. Sounds like usual BS.

I personally think its just some bad coding that Samsung needs to figure out.

On a different note, I played with the Verizon Droid Razr yesterday. Man that is a really nice phone. I'm tempted to get it, but I work for att and get free cell service, so it wouldn't make sense to pay for Verizon service, even though I think their network is better.

Android OS is definately eating up the battery now. I think it does have to do with wifi, because it seems to be much improved with it off. I'll take a free battery as long as I don't need to exchange the old one.
