Battery drainage & screen on while charging

I have had my phone since the release date (well this one 14 days after that because my original one the screen blacked out and never came back on) Anyhoo things were running great til about 2 weeks ago and bam! major battery drainage. I am doing nothing different than I was before and now after 6 hours my phone will be down to below 50%. Is anyone else having this problem? It's driving me nuts because up until then the battery was amazing! Also another issue I have is my screen stays on while it's charging. I will "lock" my screen to turn it off and a few minutes later it's back on. I have done all the "easy" checks and fixes. Sleep screen yada yada but it still does this. Any suggestions?

Thanks in advance for your help.

First, 50% in six hours is not bad if you use it a lot. When someone says "I'm doing nothing different", that usually means they're doing something different and don't realize it. Have you installed any apps recently? When you look at battery usage, what are the top consumers?

As for the screen staying on, the default action for early units was to turn the screen on when charging is complete and they're set to "stay awake" when plugged in so it never shuts off after that. Absolutely freakin' brilliant behavior for a devices with an OLED display. (OLED will burn in, despite what Verizon reps occasionally claim.) Someone pointed me to the developer menu to change that "stay on freakin' forever" setting and I posted instructions. Let me see if I can find it...

"...to enable the developer menu, go to Settings, About device, then tap "Build number" repeatedly. After a few taps, you'll see a message that says you're X steps away from being a developer. Tap Build number X more times. Once it's enabled, back up to settings and you'll see the "developer options" menu towards the bottom. Select this, then uncheck that pesky "stay awake" box."

The 50% in 6 hours is it is setting on my desk with text answered every so often. No new apps...if fact I haven't even played Candy Crush in over a month. So when I say nothing new...there is nothing new lol.

I found the "Developer options" trick after I posted this so thanks for that.

Android system is using 22%

cell stand by 14

phone 12 (which I haven't used since 5 pm yesterday)

android os 11%

screen 9% (which I have the brightness turned down til i can barely see it.

I ordered a replacement battery from Samsung charged it put it in last night left my phone on all night so 9hrs 43minutes on the battery & it's down to 68%. Which doesn't sound bad until you think that it was in active for 7 hours of that and the only things done on it in the last 2 hours was checked some email and replied to a few text.

If your phone is not running Android 4.4 "KitKat," check out the application called "Wakelock Detector." This app can tell you all about specific processes, services, or applications that are causing your phone to drain battery by staying awake. In addition, look at the battery stats in Android by going to Settings > Battery. Click on the Battery Charge graph to get more information.

See if you're able to track down the reason for drain here. Often, WakeLock detector will show offending apps at the top with either a ton of "Wake" requests as a counter, or as a long wake duration in time.
