So last night. Just like everynight I plugged in my phone. Left it on my bed. And woke up this morning. The phone was off and it was so hot to the touch I could barley hold it. No exaggeration. I actually have a screen shot of the temp when it first booted up. Its was 179° .. I don't know what caused this.. but I hope my device wasnt damaged at all last night. And I do not know the culprit. It was just random.
Here is a screenshot of the temp through francos app. Oh and by the time the phone booted it actually cooled down a little bit so I'm betting the phone hit 110°c last night and shut its self off. The weird thing is it was still hot while it was off just charging...

You should attempt to replicate it for the purpose of identifying the cause. It's likely the charger, the first place I'd start. Have you rooted? Are you OC'd? Have you recently installed a new ROM or changed anything?
I am rooted. I was over clocked to 1.5 GHz. And I actually just installed nightly #221 but I'm trying to figure out why it was still hot after it was off..

My guess is that the charger is giving it too much juice, at least when the phone is shut off and the battery full. Is it the stock charger? Also, it could be possible that the software that regulates the charge isn't functioning properly and you woke up shortly after it had shut off.
I am using the stock charger.

Would have been quite the wake up call.
I can bet you have disabled thermal throttling? If so, then: 1.5GHz+charging+some app using 100% of CPU resources = +110C is very likely.

Even at 1.5, I still don't see what his phone could have been doing to get that hot.
The only time my phone gets over 110 F is with my otter box on in the sun

Charging always locks the phone at 350mhz (keeps out of deep sleep) if it is on.

My opinion is that it is probably your charger giving the phone too much juice... HOWEVER, why is your charger giving the battery too much juice? you should check the fuses in the house. if you have the charger plugged into one of those multiple outlet bars, those tend to overheat electrical appliances. plugged something else into that same receptacle and see if it gets got over time
The first thing I checked was thermal throttle. I'm not using a power bar. Uhm. Yeah I'm not exactly sure what was up with it. The only thing I could think of was it was slightly under a pillow. But still.. I don't see it getting so hot while being under a pillow with no pressure being applied to it. Tonight I'm going to try and replicate what I did last night but with CPU spy on. Maybe there is a rogue app cause problems. Who knows. Oh and recently my phone has told me twice in the past few days that the Sim card was removed. And when I touched the metal over the Sim card it was hot as hell. I think I might have a defective phone at this point... I've never really pushed this phone. But it runs hot sometimes. Very easily. And what scares me is since I had to get a refurb.. damn insurance.. it was unlocked when I got it...
Just normally charging and light browsing right now and I'm at about 156° I'm not sure what to think of that number

Yes, I've experienced it with custom kernel (e.g. franco) but with stock kernel phone sleeps well deep during charging. (For sure I've tested it now, so this is 100%.)

I'm having awful battery life with my phone and I have no idea what is causing it. Yesterday I clocked it at 8 hours from full charge to about 10%. I barely used the phone. Very light use.
I already re-flashed several times including clean flashes. I had it in CM9 and now I'm on CM10 but it's still the same. I even tried replacing the battery but, as far as I can tell, I'm getting the same discharge rate. I tried charging it to full charge and then deplete it completely, but it doesn't seem to do any good.
Looking at the battery stats I can't see anything unusual. Screen and Cell standby are usually at the top of the list, with anything below it at pretty low percentages (lower then 10%).
Can this be a hardware issue? Appreciate any help!
I'm running cm10 with note 2 radio and CPU sleeper. I average 15-17hrs on battery .without CPU sleeper I average 10hrs.

Get better battery stats and CPU spy. BBS can tell you if something is preventing your phone from sleeping, and CPU spy can show CPU usage over time, by clock speed.

Thanks for the suggestions.
I checked CPU Spy this morning to see how the CPU acted during the night and it seems to be ok. 61% @ Deep Sleep, 34% @ 384MHz and 2% @ 1512MHz. As far as I know this seems normal, but the battery drained from about 93% to about 72% during the night. I only leave WiFi on. Is this a normal drain rate?
It seems like BBS still needs more time before it can generate a report.

+2. It would wake my phone 200 times a day on aggressive. Not to mention occasional problems getting data to turn on when I woke phone. Battery seemed better without it.
Try Gsam. To see what apps are waking phone and using battery power. Maybe its the same as BBS...not sure..never tried BBS.
Remember...its not about total battery time...its more about screen on time. I get anywhere from 2 to 3 1/2 hours screen time. And gsam has me at 22 hours average battery life.
I know you said you depleted and recharged, but did you calibrate? That worked for me a while back, now I do it every time I flash a new from which is like once or twice a week.

61% deep sleep is not good, or normal. I would look at BBS and focus on partial wakelocks to determine what is keeping your device awake.

I'm kinda having a hard time interpreting BBS. I'd appreciate if you could take a look at the screenshots and maybe see if you notice anything suspicious.
Also, I checked the CPU States in BBS and it is listing better results. 84% @ DeepSleep, 13% @ 384MHz and 1.8% @ 1.51Ghz.
So I just had a major drain. About 40% battery gone after about 3.5 hours of hardly any use.
In Parital Wakelocks, BBS showed NetworkLoacationLocator at the top of the list. But the run time for that is listed for only 4.5 minutes. In the Kernel Wakelock I got "wlan_rx_wake" at the top of the list with a running time of 1h 11m. This seems suspicious to me. Any ideas what the hell is this and how to solve it?
I've got to say, battery life is pretty bad with this phone. I bought it brand new yesterday so not sure if it needs to condition itself or not but I came from a LG G2 which has a 3000mah battery, which is slightly smaller than this but battery life was far better. Granted the screen was slightly smaller but still. Is there any Roms that improve battery life but still relatively stock?

Have you disabled all the smart scroll and air gesture stuff? Its useless and hogs battery life. Auto brightness and juicedefender and I can rock it for 2 or 3 days straight.

Ya, this sounds bizarre.. I've found this battery to be amazing. How long is it lasting? I've had mine for less than a week and I've used it heavily everyday. I have not even had to worry about charging during the day. 24 hours no problem.
Same here. The first week it was lasting all day but with only 3 hours of screen on time. After some tweaking, I'm currently getting still 20ish hours with 5-6 hours screen on time.

I just don't get it. A lady I know has the sprint variant and I looked at her settings and she had 15 and a half hours off the charger with 5.5 hours screen on and had gps and all the air features on as she's not tech smart so her phone was like out of the box and her brightness was up. I have a custom ROM with GPS, NFC and all the air gesture **** off with the screen at like 35% brightness and I get no where near that.

Also what tweaks did you make? I should rephrase that I get good battery life with the screen off, it lasts all day but screen on time is horrible.
In this pics android os and google play services is destroying battery. The screen time was only like 1 hour and 15 minutes at that time.

Like I said the battery easily last 24 hours with medium to little use but it dies fast while using the screen on, I'm seeing others with everything on like GPS, NFC and al the touchwiz things with their brightness up getting far better on screen time than me with everything off and brightness dimmed

I'm just using the stock ROM, rooted with the Kingo Root app. Installed TWRP and then Faux Kernel (hltetmo-faux123-003u)
Be warned, TWRP did trip the Knox counter to 0x1. I had to install Knox Disabler so it would stop complaining.
I was getting about 24 hours per charge, until remembered about the FauxClock app and enabled the Intelliplug driver and Intellithermal manager. About this time, I also installed Advanced Task Killer after going without it for a few years.
Screen brightness is on auto, WiFi and mobile data are both on constantly. I have not had to make many calls though, so I'm not sure how this may affect battery life...
So far, I haven't noticed any decrease in performance. Right now I've been on battery for 30 hours and I have 45% left.

Because of adjustments... Custom ROM and kernel, Screen is at 35%, gps and all location services off, NFC off, all the phones extras like air gestures multi window etc are off, I use greenify to freeze apps and I have most Google syncs off and I'm only able to achieve this. I know a lady who knows nothing about phones and has everything/feature on the phone turned on with full brightness and gets 15.5 off charge with 5.5 screen on time by the time she's at 30%. I don't get it.
Edit- I should note I made this post while stock. Because I heard phenomenal things about this phones battery and was quite disappointed.

Wow something's really messed up. Try clearing data and cache and force stopping the messaging app.
If that doesn't work then I guess a factory reset or flashing a new rom or kernel might.

Try greenify it will stop apps from waking up/running in the background, also you can freeze or uninstall stuff with titanium backup, and also monitor things with better battery stats app.
here is how greenify works, in case u never used it before.hope it helps.

Battery draining this fast while the phone isn't in use can only mean one thing: your phone is awake all the time. You had 1.5 hours of screen use but then, your phone was idle for the remaining time. I suggest you install BetterBatteryStats, it will show which process is preventing the phone from going into deep sleep (this is called a wakelock).
So I have a zero lemon 9300mah battery and got the mean bean rom been almost a month that I charge my phone fully and in 2 hours it goes to 50% so I though it was the battery. I changed the battery to a new one still died fast than I thought it was my rom. So I changed that last night to liquid smooth and charged overnight. Woke up at 8.30 and now it's 11.00am I am at 33% from 100% what's going on please help me.

Either a CPU max run state...or a serious wake lock...or both..
Zero lemon getting drained like that is a serious problem...
I would suggest a "complete" wipe...and the flashing of a rooted stock rom as a test base...
If the device still exhibits the behavior...then a hardware issue may be at Work here...
If the device gets hot to the touch....then get the device to a stock and clean state...so some unmodified testing can take place...
