If you like Google Now and want to keep it on, go to Maps > Settings > Location Settings and turn location reporting off. This seems to be the biggest battery drain with Google Now, and after doing this my battery returned to near-ICS life
I've got 61% left after 15 hours with my brand new anker 2200 battery.
seems ok to me.light use,2 short calls, quick gps.
I did notice that device wake was high
compared to screen on though :-\
Bit of an update on my battery drain .. This weekend was away and was in a very dodgy 3G area. I had wifi and GPS switched on, although the wifi wasn't actually connected to anything ... But over night it only drained 8% in 9 hrs, which I thought was really good, but I cannot understand how
Any ideas, when as you can see my my previous post, it was looking like 28% over night in less hours
I got the Galaxy S3 on October 16, 2012. I was upgrading from the HTC Amaze 4G which was a huge step up. Upon receiving the phone I immediately proceeded to personalize my phone and perform little tests on it. And I fell in love with it right away.
A few weeks later after I had my phone all set up I went to "Software Update" and found that there was indeed an update. Being an eager littler f*cker that I am I decided to go through with the update thinking that it was Jelly Bean.
After the update I immediately noticed that my phone was acting weird. Seems like every time I would be inside any app that requires an internet connection my internet would not work. (Facebook, Twitter, Scramble With Friends, Tapatalk, Skyvi, Maps, Poynt, Transit Tracks, Browser, Gmail / Email, ect.)
So at first it wasn't as bad because I could just restart the phone and my internet would pop back up for like 3 minutes.
I went back and forth with tech support and they told me to perform a factory reset so I did. Afterwards my Play Store (as it required an internet connection) didn't connect to the internet and I couldn't download any apps and finally I got the phone replaced. The T-Mobile "maintenance update" killed my phone.
So here we are again with another update from T-Mobile. This time I know its JB. So I say f*ck it, lets do this!
Updated my phone, put it on the charger and went to sleep.
Next morning like a kid on Christmas morning I sprung to my phone looking to play around with it. Snatch the charger out of my phone and go to work. While I'm on the bus I start doing routine things with my phone like play Scramble With Friends and start writing out a few text messages.
By the time I got to work my battery was down to 84% and its a 45 minute commute.
Usually with the same amount of usage I am able to do the same things everyday and I'd get to work and my phone would be at 97%.
So I gave it a few more days.
Now I don't even use the phone in the morning.
I took the phone off the charger today and went to my bus stop. By the time I got to the bus stop I was already at 98% and my bus stop is super close to the house.
So this is the second update to bite me in the a$$.
I want my ICS back. So now I'm going to have to root my phone. I am very upset.
I was looking forward to Google Now but not any more. I am tired of charging this thing. My HTC Amaze 4G was horrible with battery life too.
WHYYYYY?
WHYYYYYYYYYYYYYYYYYYYYYYYYY?!

something seems to be waking up the phone every 30 minutes and I havnt even installed any apps yet.
Did you find out what's waking up your screen every 30 minutes? I just noticed mine doing that today. Perhaps by coincidence after installing a Easy Task Killer.

I've been noticing this issue too. i.e. much greater battery drain after JB upgrade. I was getting great standby time on ICS (and also DIDN'T have a whole host of other little issues that have been plaguing me since the 'upgrade.') If I could easily get my phone back to ICS, I would. It worked great then and I wasn't obsessed with the battery life all the time
I realized that although I have turned off google now, I hadn't turned off the location history. This is THE major battery drainer because Google is using juice to constantly monitor where you are so it can readily provide you with local suggestions. This is pointless, however, as Google can ping your gps when needed just by turning this option completely off. I'm hoping this reduces the standby battery drain. Today I averaged about 7.2% / hour and I've turned off most obvious battery drainers.
Hi everybody. I am new to the thread. Please read below, it seems to be a definite solution to the battery drain issue after installing Jelly Bean 4.1.2.
A few days ago I installed the update (Jelly Bean 4.1.2) to my Samsung Galaxy 3. After the installation, my battery was going down like crazy. I did not want to go through the process of doing a hard reset, so I did something very simple which I first read in another forum. I used the phone until the battery was completely discharged, that is until the phone switched off by itself. After the device turned off automatically, I pressed the on button to make sure that I could not turn on the phone - in other words I wanted to make sure that the battery was completely discharged.
Then I charged the phone until the green light indicated that the battery was 100% charged. I unplugged the charger without turning on the phone, waited for about 10 minutes and then I plugged in the charger again. I noticed that the led turned red, indicating that the phone was again charging. I charged until the led went back to green (that is for about 10 min, but it might be better to charge longer, maybe for an hour). I unplugged the charger, I turned on the phone and the battery life went back to normal after that. It now discharges at about 1.2% per hour - I am happy with that.
Please follow the above process. It should work with everybody who has a problem with battery life after the Jelly Bean 4.1.2 update. I am not a tech guy, but it might have something to do with battery memory or something like that.
I hope I helped. If yes, please spread this solution to this and other forums.

HTC used to recommend this. Its not actually healthy for the battery. That's why they stopped recommending it.

Yeah it works but if you keep doing it, you'll screw your battery.
A better way would be to let it drain to as low as it can. What happens is your battery has a chip that remembers the max and minimum capacity of the battery but over time, if you constantly recharge your battery at 20%, it will start to view 20% as the lower limit (and show it as 0%) so to let it discharge down until it turns off is good as it lets teh chip "see" the entire capacity. Making it aware of it again.
Original battery on jelly bean my best day was yesterday with 1d and 6 hours worth of battery life with a screen time of exactly 2 1/2 hours. I feel pretty good about that. Verizon 4g lte

Thanks for that SUroot. You are right, it's not good to do it often - actually I 've never done it before. I just did it once to "reset its memory" and now it's working perfectly - my battery draining problem is completely resolved after the Jelly Bean 4.1.2 update.
I've not seen any mention of ActiveSync on this thread so far.
My S3 is a work phone. One of the reasons I have got it is to access work E-mail so ActiveSync is essential.
Since moving to Jellybean, My phone has discharged to 30% by the time I have got home. I have tried reducing the sync frequency but this does not appear to have had an effect.
Is there anything else I can try other than to switch it off, charge it then charge it again?
I wonder what kind of technology we will see in future Samsung devices like 5-10 years from now. Hopefully they'll have some type of super battery that can last a week or more :-)
