Just wondering if anyone has had bad battery life while running KitKat on their gs3.

I get about 7 hours. Used to get around 11-12 with moderate usage with 4.2.

Anyone running a custom kernel?

Open to input and suggestions. Thanks in advance!

You won't be able to run a custom kernel if you have a locked bootloader. I've been running AOSP based KitKat roms for months since I never took an official update, and 14 hours is usually a non-issue.

I used to get 12-15 hours on 4.3 now with KK4.4.2 I get about 7-9 hours now. It's definitely a battery drain! I even replaced my battery and still doesn't help.

Have you tried a factory reset after taking the update?

Sorry I didn't mention this. I am rooted and I have flashed a custom ROM. Carbon to be exact.

Im stock and Verizon did a complete wipe of the phone and loaded 4.4.2 right to my phone. Didn't make a difference. They are claiming it's hardware but I don't believe that especially since I'm out of warranty.

Oh, that makes a huge difference. Look for Steve Spencer on Google+. I'm running his latest CM11+ build and getting ridiculous standby time.

People reading this can't use aosp, no cm11 unfortunately.

Anyone tried switching to ART runtime? Might not notice anything, but in theory it should save some battery with how the runtime operates. Switch to it, then let it settle for a few days and see if you notice a difference. It'll definitely boost performance.
