I was looking at logcat and saw that there is a garbage collection happening almost every second! This happens even if the phone is asleep. If you disable WiFi calling it goes away.
This garbage collecting every second can't be good for the battery.
Does anyone else notice this, can you check?
See screen shot for sample.

in any case, i wouldn't worry about it so much. it can't be any worse than your device constantly scanning for a good radio signal

I've done extensive testing for overnight power consumption (no use at all) and you save about .2-.3% an hour with wifi calling off with poor signal (my house reception is horrid) and with wifi on. This amount is probably small enough to be considered negligible.
Any graphs from settings > battery to back this up?
My other device has this feature but nice never thought to test it.

It really may not effect battery life at all. I'm mostly wondering if it happens to anyone else.

so in my church my phone has almost no signal but my friends with Verizon and other phones than the galaxy nexus have better signal than that of mine.
what I usually do is just
1. turn the data off or
2. put my phone into airplane mode
when i turn data off, after about 30 minutes my phones gets crazy hot for no reason. and sometimes I have to do a battery pull because it doesn't respond to anything.
today, I put it into airplane mode and it didn't get hot. but after about 2.5 hours, I had gone down from 100% to 75% battery life. also it showed that "media" was 95% of my battery use.(I tried to take a screenshot of the battery but it keeps saying "couldn't save screenshot. storage may be in use"
and my phone was awake the entire time.
this only happens in my church...
does anyone know what is causing all this?
it just seems so strange because I have no problem with my phone anywhere else. I'm running liquid 1.1 and the minimalistic kernel 2.7.1stable if that relates to anything.
no idea, but the power of Google has put an advert on this thread on the xda app for Christian dating nothing is sacred from el goog!

Your phone has been possessed by satanic forces which is why it is happening in church.
Try getting it exorcised or better yet throw it into a bucket of holy water for an hour and of it still works when you take it out you'll know for sure it is possessed.

I get phenomenal battery life out of my S3 (stock).
I had an Epic 4G and was afraid to leave my desk because of the battery drain. With moderate usage (30-60 mins talk time, texting, chat, some web, exchange, ect) I can easily get 16-20 hours. Signal quality in your area will impact it more than anything. Also, wifi is vastly easier on the battery.
PS Facebook app SUCKS. Just bookmark the webpage and use that. Works better and doesn't ruin your phone.

You can improve battery life by switching to custom roms with less bloatware, and updating to more efficient kernels. (This is on a Rom/Kernel level)
Software wise, just figure out what apps are causing wake times and try not to use them. Basically whenever an app/widget refreshes/updates content, it may cause phone to wake (like weather/clock widgets for example).
I have been using cpusleep and it seems to have helped my battery life ... also using a custom rom without the bloatware is key for me.
my current setup is freegs3 release 6 with the latest trinity kernel...even though its overclocked my battery has been amazing and phone has worked flawless.
Im also using system tuner which has given me the ability to manage the cpu with on demand and other customizable settings
The only thing I synch is my k9 mail account
I also have frozen several samsung apps which helped...
Im now getting over 20 hours of basic use between charges...I dont use games/videos so might be a little skewed . I use this phone for business calls/internet/messaging/photos/navi...pretty basic

I have been using Gigajoule lately by feckmu and it has given me the best battery life out of all the custom roms I have tried. Even with GPS, WIFI, and screen at full brightness I can make it through the entire day with 30-40% battery left. If your looking for a rom-based solution to your battery life, check it out!

The GS3 does get hot when it's working hard. That's why people are suggesting a list of what apps show up on your battery list. How is your battery life? If you provide a screengrab of the battery screen that shows the apps and the activity it could give the folks here some information. It's most likely an app that keeps the phone awake and running at full power.
Agreed a screen grab would be excellent, I just found an app that was draining my evo4g from full to absolute zero it was ridiculous especially with a 3500 battery on board. Still waiting for my S3 in the mail, but steal my friends to mess around with when I can 'b

Tried it. It's pretty much worthless. Turns off wifi when away from your access points, which is cool. Otherwise, all it does is prevent your major apps from updating to a varying degree. It's better to just control this yourself in app settings and "Accounts and Sync" settings. I think the app was designed with people who don't have a clue about Android sync settings in mind. For the type of person who spends time reading Android forums, it's a waste of time. Sorry
If you do choose to use it, be aware that depending on the setting you or it chooses for Gmail, push notifications may not work.

Incorrect. This app has nothing to do with CPU. It automates turning on/off wifi, and blocks or reduces syncing for various major apps.

I've never had it change my syncing but i turned off the auto-wifi change in the settings menu, i hate apps changing my wireless settings
As I write this, I am currently 32% with 2 hours of display time. That's horrible compared to other people's battery.
I installed the ktoonez kernel and copied his exact settings but that didn't make a huge difference :/.
I have no idea what it is; I've disabled GPS, i have auto-brightness on, and i have sync turned off. I just don't get what's killing my battery...
If anyone who has the ktoonez kernel installed, may you please share your settings! It would help me a lot!
Or anyone who's reached 4 hour on screen time, please share your settings !
And I use the phone in a moderate fashion, just text, send photos and use the xda app!

Your phone is a phone. Which means that unless you're in airplane mode (which I'll assume you're not since you didn't mention it), it is always sending and receiving information over the air. The quality of your signal will determine how much battery you use. Comparing your results to others that have the same phone is meaningless unless you're both either (a) in airplane mode or (b) at the same location using the same cell towers.
Maybe you have a weak signal wherever you are running these tests, and your battery is working overtime because of that? That's just one guess.

Well if you want to be really scientific about it (though this will be a huge PITA), flash the same exact software image to both phones, then repeat your test using both phones simultaneously. After this, if the phones do not perform identically, then recharge the batteries, swap them, and repeat the test.
This would identify whether the problem is related to the battery or the hardware. If it's not either of those, then yes it probably is software. Good luck!
