I am wondering if there's a difference between Jelly Beans and Kit Kat kernels' CPU VRM (Voltage Regulation Module) setting configurations, as for some reason my phone did run too warm for my comfort. (Long since taken care of.)

How did you take care of your phone running to hot?
Sent from my XT907 using XDA Free mobile app
I decided to swap out with CyanogenMod 11 because their kernels always have CPU voltage set at conservative settings so out the stock OS goes. Apparently, there are few complaints, ranging from broken fastdormancy app, up to stubborn Google Play service threads, in the stock Kit Kat update.
There was/is only one benefit in Kit Kat update: unlockable bootloader. I held out on updates until it's determined that it's worth it - I ran my phone on stock update for a day. Too warm for my comfort (I don't have the desire to deal with battery fire). There is one version of Verizon Kit Kat stock OS that have had the problems taken care of (Google Play Edition) here in Development section.
Disappointed that Verizon submitted an update that's obviously broken.

Discovered two bugs in the bootloader: wrecked battery management system microcontroller image (which would have explained the obviously incorrect battery charge percentage in both stock and CM11) and CPU's watchdog timers not working correctly (the weird phantom lockscreen occurring even when the phone is unlocked and rarely the phone would lock and refusing to reboot - necessitating the two-finger salutes to force the phone to turn off and reboot). All in all, the only real fix for me was to downgrade back to Jelly Beans.

Isn't it also part of RPM?
What if you flashed another one (e.g. from JB)?
It certainly was. That's the bootloader that was causing problems in CyanogenMod 11, apparently. Without watchdog timers, well CPU is free to misbehave whenever it wants to. I had to downgrade everything, except for GPT and TZ, back to Jelly Beans, and it solved the problem.

So 4 times now i've let the battery fully discharge and charged the phone overnight, turned it on the next morning and its in recovery? First thought was it was because when I was having issues with the market but my market app has been working without any problems since removing updates.
Is there a setting I need to change or is there an underlying problem that is rearing its head.
Running GB rooted, never had any ROMS pretty much just rooted thats it.

I believe it's supposed to do that. I think it's a sort of fail safe system that comes from the hijack process used in the Droid 2/X Bootstrapper.

I just got a gs4 and am coming from the gs3. Does this phone run hot normally? Seemed warm on stock and hotter once I tried to install the freegs4 ROM. Even shut down twice.
Edit: flashed a different ROM and kernel and am all good.

Yeah I noticed when flashing certain Roms and setting it up, it gets very hot that it shuts itself off.

Not true on my part. I've flashed stock deodexed MF9 rom with Stock MF9, Agats, and Ktoonz kernel. All resulted in the phone heating up and shutting down on its own.

So I have tried 4 different ROMs and 3 different kernels and the heat issue keeps happening. Right now I was using the latest Venum ROM and the ktoonz kernel and the phone shut off due to the heat. Stupid phone, I just got it on Sunday. Never had this issue on my epic or e4gt or gs3.

The only kernel adjustments were to the governor and scheduler (using smartass and sio, no alterations to either). I just tried using the rescan media disabler apk to see if maybe my media was causing the phone to run hot. It seemed to be the only thing going in the background.

Usually the heat starts when I am using the phone, which is usually browsing the internet or reading up on sports news. Screen off or charging I have been OK so far. As far as the battery, it appears to be in good physical condition. I also have 2 OEM batteries by Anker that experience the same issue. So far so good, though - been using the phone moderately since the last shut down earlier today and it seems ok at this moment.

if it heats up really bad again try underclocking a step and see if that helps.....phone might be getting hot because your chip is poorly coated and the higher frequiencies are heating it up enough to shut the device down. you may have to underclock by one or 2 steps to ensure its not a consistent issue.....worth a shot anyways. unless you do high graphic gaming and multitask with 8 apps at once your really dont need the higher clock speeds anyways.

Good idea, hopefully I won't need to! Appreciate the feedback.
If you just got this phone Friday then I would return to stock, run triangle away and exchange it. What you describe isn't normal, why take a chance and get stuck with a bad phone when you are within the exchange window.

Try the stock kernel and rom and if it still get hot take it back. Try stock kernel it works man the others just cause me trouble.

Thanks all. I loaded up the latest Sac ROM and ktoonz kernwl, but disabled media scanner. No more hot issues. I guess it running like crazy in the background caused the battery to commit suicide.

Seriously guys, your S4 doesn't heat up at all???
I'm back to 100% stock everything (kernel, rom) and running this for a couple weeks. I've completed several factory resets and whatnot as well through those weeks. I know my install was clean as could be.
Now, my phone gets hot at seemingly random times. sometimes playing games, for sure while navigating with GPS and sometimes when its just sitting there. I monitor things with Better Battery Stats and keep an eye on the CPU Spy. I'm achieving deep sleep most often. Some of this is caused by the god awful Sprint service here and the constant search for signal, but I was hoping that this wouldn't get as hot as the S3.
so, should I seek a refurb from Sprint? I have the insurance. I am just afraid that a refurb would do me no better.
My biggest gripes are heating up occasionally, WiFi disconnect issues. I hope 4.3 can help some of these.
So I had pacman v22.0.0, and I used survival mode on superSU pro to keep root, and flashed the pacman 4.3 update. My phone started lagging, overheating, and taking forever to charge. On 4.2.2 I had a few apps always running but rarely used more than 800MB of my RAM, but oh 4.3 with all the apps running the same, my RAM usage is normally about 1.4GB.
I'm assuming this has to be 4.3 right? Is it just me that's missing something, or have other people had the same experience with this?
Either way, if you're not completely running out of free ram, you have nothing to worry about.
Nope its not an issue with 4.3. I have few apps running with 800mb used . I am using PA 4.3. Never noticed any lag or overheating problems. It could be certain apps causing the issue?
Sent from my Nexus 4 using Tapatalk 4
Why don't you check in Running apps to see what apps are taking up your rams. I have been using 4.3 custom and now stock and its usually 400mb or less.
I assumed it was the fact that the pacman ROM had so many customizable options. I have the same exact apps running as I did before I updated, but my RAM usage has almost doubled. I know I have nothing to worry about, but when my phone is hitting 120 degrees on average, lagging, and the battery still drains while it's on the charger, I figured it's either the ROM or the fact that I didn't re root, I used survival mode. I checked my app usage, but the apps aren't accounting for most of the usage. Something else is, and I have no idea what.
With stock Rom and sometimes I can see 450mb Ram available.
So what?
Phone runs still flawlessly with no lags.
Don't get upset by numbers.

Guess it's rather the overheating and lagging that upsets him
You probably know this already, but it's not because of 4.3. Never had anything like that on PACman or CM10.2 - only once with a different kernel while navigating. But it just overheated, didn't lag or anything.
You should have flashed the factory images instead of just the zip;

You obviously misinterpreted him. I guess he was trying to help by comparing to his situation. Maybe he just didn't understand completely what your real problem was, but I doubt that he tried to birch you
But as was mentioned here before you should probably flash latest bootloader and modem. Either by flashing the factory image or by flashing a zip that contains both bootloader and modem.

Same here...ever since I updated my PAC 4.2 to PAC 4.3 my average ram usage is 1.4 to 1.8 gb with same number of app usage...previously it used to be 0.8 to 1.2 gb...no lag however..
P.S. it was a clean install with updated modem

Change your rom and kernel.
Sent by reversed alian technology.
Didn't need to change the ROM or kernel, I figured out the RAM bar was showing me running, AND cached processes together. There's actually only about 400mb of running processes. All the other stuff was cached. Didn't notice it till way later.

Hey guys I'm on an AT&T D800... since Monday afternoon my phone had been unusable... it got extremely hot both front and back near the mid to top of the phone... and was just chewing through battery 31% in 15 minutes... so I powered down and left it numerous times on different stock based rooms and still no luck it would just overheat till it shutdown or battery died if I didn't turn it off... I managed to get it charged enough to restore my stock backup, unroot, and put the stock recovery back on and then did 2 factory resets with still no change... so I called at&t and they sent out a warranty replacement which will be here tomorrow.. so my question is do any of these return to stock methods actually clear rootchecker? That's my only worry that they'll see that and nail me the retail price of the phone... I didn't use a custom kernel just the roms...
I see conflicting stories from people saying yes it does it clear rootchecker and others saying no.. I would just try but I don't have WiFi so I don't burn up my months data just to find out it didn't work.
The phone seems to be working fine since I powered it up 2 hours ago but I'm worried about any residual/repeat issues or decreased lifespan of phone from the overheating issues
Thanks in advance!

Did you check to see why the battery was being depleted so fast? I am willing to bet the phone itself was fine, but some app was utilizing the entire CPU, which would heat the phone up and kill the battery quickly.
Which means it's entirely possible you'll have that issue with the new one as well.

This happened to me when I flashed SlimKat 7.6. I all I remember is that it got insanely hot, and didn't turn on until the phone cooled down completely. If this not your only phone, i'd replace the battery, and while you are replacing the battery check if there is any signs of damage from the heat. If it is your only phone, I would just keep a cable with me at all times.
