I've had my phone for about a week and the battery life seems so-so. I am not rooted or anything and I don't have any of those battery saving apps like I did on my previous android devices. My phone seems fine with WiFi, but it's when the WiFi is off that it drains battery a lot, even in sleep mode. I understand that WiFi uses less battery, but I don't think it should make that much of a difference when your phone is sleeping and your not using it. Usually, my battery stats say that cell standby is using the most battery. Not sure why since I live in an area with good cell reception. Any suggestions?

7 hours of heavy usage, Brightness at 20% (auto dim and power saving mode both off), WiFi and 4G both on, GPS on, and push email notifications and weather all sync hourly, I'm now at 38% . My old iPhone would've died long ago with this amount of heavy usage. And with JB update on its way, battery life and performance will get much better. Very happy with my GS3 so far

Which Android version are you using? From 4.0.4 (and also in Jelly Bean) there is a very significant improvement in battery life. I would suggest (including the typical kill apps) to upgrade to the latest android versions.

Good luck!

So letting the battery settle for a few weeks did help. I'm now getting around 14-17 hours with moderate usage and 8-10 hours with heavy usage (with everything on including Power Saving mode). Unplugged it yesterday at 7:30am and I had 30% left at 3am. Very happy with the results so far. What a beast of a phone this is once everything is working fine

By doing this, does this mean that when I hit the icon on the screen it WILL open up...I know that may sound like a stupid question, but Im so afraid of disableing something and not knoiwing how to fix it.

Also, your phone isn't really off. It's asleep. The only way to turn off your phone is to power it down. Hold the on-off button down until you get the message that the phone is shutting down. That's another way to keep your phone from polling all of your push apps without resetting everything.

I too am not happy with the power consumption. Luckily, most of the time I am by a power supply, but there are times when I need it to run a whole day. I also get only about 5 hours before I am at 30%. That is with moderate usage, following the advice of most people on here. I should note that under similar usage pattern my iPhone 4s would be at 70% or more. Granted the phones beeps and vibrates more (I guess I could change those settings), but I'm not really using it much. The part that gets me is that it says cell standby is consuming 32% and display 32%. I can understand display at 32% (well not really because I am not on it that much), but why is cell standby so high?

OK, I just noticed that Gallery is consuming a lot too. However, I have not even opened Gallery. I viewed a bunch of pictures on an e-mail, last night, but that's it and then I charged it overnight. Today I didn't look at any pictures. Even though I force stop it in Battery, every time I go back to battery it is running again. I went through my gmail accounts and unchecked sync images, picasa, etc. Any other ideas?
