Phone gets real warm

I'm not one of those that gets 26 hours on a battery. I use the phone a lot! It always gets quite warm. Hasn't really caused any problem that I know of, but anyone know of why?

I think im the only one who doesnt have the overheat issue

I read somewhere that one or both of the cores aren't managed efficiently and switch govenors from ondemand to performance which the phone isn't optimized for causing the heat issue. I actually put my phone on performance and it did get hot so I think this may be true, I heard that there was a script or something that fixes it called restore dual core or something like that but I think it was for the international S3 so I don't know if it will work with our devices.

My stock rom also used to make the phone heat up but it's always at the very bottom. Anyone know why that it?

My phone use to be very warm and then I changed to FrostyICS Rom and now it only a little and none most of the time

It's gotta be the name "Frosty"
I'm on stock and it heats up at the bottom only if I've been surfing the net on wifi for a long period of time or when it's charging...and I'm surfing the net

I figured that the phone heats up due to processor usage.
My guess would be that the processor is located behind the home button, therefore when you're running an intensive task (or doing somethings in general) the processor has to increase the clock speed thus heating the device.
It's really annoying actually, makes my hands sweaty sometimes when holding the phone.

I think i might know what your problem most of the web browsing dolphin, Firefox.......etc still loading in the background or spending ( maybe just me ) on top of the page even doe you go to the home screen or used different app that why it killing your battery and heat up

I had this phone heating up on me while I was on stock too, but ever since I switched to AOKP with Lean Kernel the heating has been dramatically reduced for me. And by dramatically reduced I mean it rarely heats up unless I'm doing something up that takes a lot of processing power like a 3D game.

[Q] Seeder entropy generator, does it make a noticeable difference?

http://forum.xda-developers.com/showthread.php?t=1987032&nocache=1
Worth the plunge? Still not rooted since I don't see the need as of yet...

Seems like it's snappier. Could just be perception but check it out and see.

I have a very noticeable difference.

Seeder Entropy Generator is such a cool damned name who cares?

found to be useless

Thanks T3. I was half tempted to try it.

Well sorry but it definitely makes my system faster no matter what these other people say. I find for instance that Tapatalk can get hung up quite easily but when I run this mod forums load instantly every time.
So, try it out and see for yourself.

Or instead of using the app (since it murders the battery life) you could just change the min frequency of your CPU to like, 600mhz or higher and it does the same thing as this app

No it doesnt do the same thing. I have my cpu set at 1800 performance and this mod clearly makes a difference above and beyond that.
And it may burn battery a bit faster but it doesn't "murder" your battery. I've been heavily using my phone with the mod on for 6 hours and have used about 40% of the battery. Pretty normal burn rate for browsing, texting and watching netflix non stop.

How much do you undervolt?

My S3 was getting really hot after rooting so I decided to try undervolting. I was able to under volt each clock speed by -100mv, and my device hasn't seen any performance issues, runs cool, and battery lasts way longer! What do you guys keep you voltage settings at?

It doesn't matter what other people UV since all devices are different. I can reach -125 all steps (haven't tried farther) but some others can barely do -25. It's just how their device is built.

I understand. I'm just wondering what people are running at
Sent from my SGH-I747 using xda app-developers app

The reason I personally don't do both under clocking and over clocking is that the phone itself isn't made for that. I personally don't know what this phone can handle. I have seen people under clock and over clock phones and have it work while some people have phones that can't handle much at all especially the refurbished ones. My S3 handles it well but I only tried it out once. That's my feeling on the subject. If you do do either undervolting, under clocking or over clocking just remember to do it responsibly and not put it to highest power and leave it there.

Does force hw acceleration do you more good or bad?

How's battery consumption compared to not forcing it?

Usually forcing the use of GPU does cause a difference in battery life, but the difference is unnoticeable. Maybe half a millisecond less of battery life.
Edit: My info may be wrong. I just read this in ICS days in a similar thread.

It should increase battery life since hardware acceleration usually means less stuff for the CPU to process which equals power savings.

I enable it on every ROM i use after ramping up GPU to 384 without really thinking about it. Always has been solid for me. And yeah, im gonna say that it doesnt do a 'whole' lot for battery. But hey, another 5% on a charge? I'll take it.

Is it possible to bypass the auto shutdown due to temp?

It's there any way to disable this? I am on stock ZVB rooted with I.A. installed. My phone will shutdown due to temp constantly, especially now that the weather is getting nice out. This is getting to the point of being a deal breaker with this phone. Will a custom ROM help? I love this phone but this is getting to be unacceptable...

Never heard of such a thing. Try a kernel mod app like Fauxclock or Tricksters mod. Might make all the difference. I swear by Faux's myselff, and have great performance, battery life and no added heat.

There is but it's not recommended. The phone shuts off in order to try and make sure the heat does not damage the hardware permanently. If you're phone is shutting down that often due to heat then it sounds like you need to get it replaced. I've never had it shut down due to over heating, even after hours of playing a graphic intense game with the screen at max brightness and charging..

Thanks for the info. Glad to hear that you can play games/charge/etc.. cuz I couldn't even play Ingress and have BT enabled for more than a few min if it was above room temp outside.
I was wondering if it was just my phone, which it appears that it is. I will take it in as I have the BB ins. I hope it's an isolated issue cuz I do really like this phone.

Got my LGOG replaced at BB and it is definitely better! Its kinda sad that I feel like this is an upgraded phone but it seems faster, smoother and overall better. AND no more shutdowns! Tho I'm paranoid that it will, it finally runs CF bench no prob.
