There's basically nowhere for the heat to go with this phone, and with a quad core on jellybean, some heat is going to be produced no matter what. I wouldn't worry too much about it, especially if you're stock.

If you're rooted try messing with the governor settings. I'm running ME's kernel at 1.67GHz and my phone never gets hot even with games. Try these settings except where the powersave bias is. That is changed by the built in eco mode. With these, the phone only goes above 1.13GHz when scrolling to improve performance and for performance demanding apps like games.

Mines gets as hot as it used to on ICS. Try to do a hard reset and see how it goes afterwards.

Mine gets just as hot as when on ICS. Still hits 91* if I play real racing 3 too long haha. Really annoying when I have to answer the phone at that temperature

I had the same problem. After updating to JB, my phone started getting really hot and the battery drained after only a few hours of use. It used to last all day. I tried going back to E97011c, but now I'm having trouble with my wifi. It scans and finds the wifi, but it won't connect. Any ideas?

You'd probably need to change modems.

[Q] Is battery temperature at 122°F bad?

I was playing Crusade of Destiny (full scale 3D single play RPG) while charging my phone and noticed the phone was feeling really really hot.
My phone is on Bionix 1.9.1 (OC/UV/VooDoo) and I used SetCPU to OC it to 1.2ghz.
Being me, I didn't want to melt my phone so I stopped playing and used SetCPU to check my battery temperate- low and behold, it was a little over 122°F. I went ahead and cooled the phone down asap by putting it in the freezer for a good minute or so and temperature went back down to 98°F.
My question is, at what limit should the temperature be at to insure myself that the phone will be okay?

I set up a profile on SetCPU so if my phone reaches ~120F it give me an audible warning and clocks it down to 800 max. I know some ppl have had problems with profiles, however, they work just fine for me. I have heard that the Vibrant will start getting screwy around 125F, so best to keep it under that.
Ah, didn't know I could set an audible warning with SetCPU.
Wow I was closing to screwing up my phone then. Scary.
A lot of people report it heating up like that when charging and using the phone at the same time. If it ever got that high, I think its common sense to stop playing or maybe close what your doing (3d games or something heavy on the processor) I personally never got past 120 F...
I'd at the very least not OC. That game runs well with the stock kernel and no lagfix

I would strongly suggest NOT putting your phone in the freezer. ESPECIALLY when its running hot. Sudden temperature changes tend to crack electronics.
If you're worried, unplug it from the charger and turn it off. Maybe take the battery out (carefully).

that's hot. my phone never gets past 110 when charging.

Other Battery problems...
I'm running 2.1 w/ one-click root and one click lag fix. I uninstalled ATK for the stock task manager set to strict, and I usually have wifi and gps. Ever since rooting and teh lag fix my battery has been hot battery is draining very quickly. Next thought is to just make the jump to 2.2. Any help or suggestions would be greatly appreciated.
When I flashed to Project Core kernal 1.2 and severe heat problems. Especially when overclocked passed 1 ghz you're gonna have heat issues. I don't really use my phone as it charges and i kill tasks that are not in use. Currently I'm using project core kernal v1 1ghz and its working great for me.

[Q] SGS II screen & back becomes hot

Hi guys!
Just got my SII yesterday. After couple of hours use I admit that the phone becomes hot even on normal usage, like downloading apps etc. The back of the screen as well as the screen itself slowly becomes hot. If i continue to use the phone it gets worse! I'm really confused n kind of scared. I've a iphone 3gs which rarely became hot. So, can u guys please tell me if its normal with SII or its just my unit that's got some problem?
Oh, sorry if its a duplicate thread. I've seen in different websites people saying it become hot when playing games. In my case since I had my phone I didn't even install a game yet! What I did is installed couple of apps, widgets and I use mspot to sync my music(446MB) over internet.
Any suggestions and advices appreciated!
It's normal that it gets hot when you use it
You have to remember that it's a dual core 1.2 ghz proc... and Yes it's normal..
Thanks for the replies. What concerns me most is the screen becoming hot and that I don't know if anyone else is experiencing this. How about u?

a part of the issue is it is a 1 GHz CPU overclocked to 1.2 GHz, so whenever your activity demands 100% of CPU, it gets sped up to 1.2GHz and gets hotter than needed.
But yes, excessive heating is not a defect, the phone is just too thin and tightly packed to dissipate heat effectively.
Actually, i dont think it's normal
The processor sometime get stuck at 1.2GHz in my device
whenever ur phone get too hot, go and check SetCPU, if the phone dosent get below 1.2 when idle, then reboot
My guess it's a kernal thing
Not normal. Mine doesn't get hot even when gaming. It used to get hot before I updated the firmware. Now it does not.

I had the same issue, it dissapeared after I flashed to KE7
Thanks for the replies.
Well, it seems yesterday my phone was warming up even in normal usage but now after using the phone for over 4hrs(after full charge) and a lot of usage(videos: 60-75mins, downloading apps, music: 40-50mins, little web browsing & checking fb & mail and sync & wifi always on.....) temperature is around 30 deg celsius.
Next thing giving me trouble is the capacitive menu button which wasn't working at all since yesterday(back button was ok). Last night, sometimes it worked for a few seconds and dead again. I was thinking I should call O2 for a replacement, suddenly its working again today! Guess its a software problem.
Another thing I'm concerned about is the battery life. After charging it to 100% and after the above mentioned usage the battery level is bellow 40% after only 4hrs. Well, brightness was 0% most of the time which is ok for indoor use. Its quite funny that the phone doesn't seem to discharge faster when playing videos(at youtube & vevo) compared to browsing web. In the review & battery tests at gsmarena they mentioned battery life is very good and can last almost a day with heavy usage. What u guys r experiencing? Is it similar to mine or mine has got a faulty battery.
which firmware are you running?
I'm on O2 as u r. So I guess its the same one. If not, mine's build number is ....XWKE2, baseband: I9100XXKDJ
NB: I'm using the stock firmware, didn't root and didn't use any optimisation app like juicedefender. And display brightness is on 0%, always on wifi.
KE2 is a little buggy, you try updating to latest firmware build KE7, might solve your problem.
you can do it if you connect your phone to your pc and run kies, or reading in the dev section of the forums there is a sticky there that informs you how to upgrade firmwares.
Thanks for the reply.
I use mac and the kies mac is in beta and won't let me upgrade(option disabled). I've tried the windows version of kies(downloaded directly from samsung portal) via paralles desktop for mac(lets u use windows app in mac) but it say mine is the latest version(ke2).
And the capacitive menu button is dead again! Is it possible that this is just a software problem? Or should I contact O2 for a replacement? Its my 3rd day with the phone so I've to report ASAP if i need a replacement.
The battery also feels faulty to me. It turned from 100%-1% with only 8hr of usage as follows:
videos: ~75mins(mostly HD),
downloading several apps apps,
music: 50+mins,
little web browsing,
checking fb, rss feed & mail,
sync & wifi always on,
brightness most of the time at 0%,
fring chat: 50-60 mins
And it took 3hrs to completely charge it up. Is it normal for you guys? Or should I request for a replacement? Any suggestions appreciated!
i have debranded my phone from O2 and upgraded to KE7 from kies, but if you cant do it that way you can try upgrading thru odin.

This thread has multiple firmware versions and instructions on how to flash your phone (please note, if you decide to flash your phone, you do so at your own risk, even thuo the risk is quite small).
As for battery usage, i have rooted my phone and frozen a lot of bloatware, if i leave the phone on standby with wifi off the battery drains lest than 1% each hour, with wifi on its about 2% each hour.
Also i find that when i play angry bird a lot i have to recharge after about 6-7 hours, when i watch videos my phone heats up a little, it heats up a lot if i watch videos while charging.
hope that helps you, if not talk to the ppl at O2 to see if you can get it swapped out, but i think if you can get your firmware upgraded your battery drain should reduce and the shouldn't heat up as much.
Thank u very much for the replies. It looks like battery draining is normal for all SGS II users. Its kinda funny that playing videos over internet eats less power that browsing web(27.19min of HD video playing at vevo over wifi drained only 5% of battery!).
So now everything seem ok except the capacitive touch keys which sometimes which doesn't work most of the time. I'm just scared to use custom roms as it might void my warranty. Well, I'll try the link u mentioned and see if the problem still exists.
Thanks again

What system process is causing 100% CPU utilization?

I use SystemPanel to monitor running processes on my phone. I recently installed SimplyHoney 3.9 with a Bullet JVP kernel. It was working great for a week or so, but now all of a sudden I am noticing that my battery is dying. Fast. Really fast. So I went to check SystemPanel to see what was hogging up my CPU time. That's when I saw that my CPU was pegged at 100%, and that the SYSTEM process was responsible for about 80% of my CPU time over the last 8 hours, and that it was often times running at 100%.
Rebooting doesn't help. I was thinking about reflashing, but I am pretty doubtful that will help. But you never know Anyway, is there a good way to see exactly what in the system process is misbehaving?

I was getting around 30 hours too. But now I can't get much past 12. Something changed, that's for sure.

change suddenly or do it a bit at a time ??
maybe something you downloaded ??
could do a virus check, doubt you'll have a virus but its worth a shot ??
Download Android Assistant from the Market (it's a free app), go under tools, and look at the Battery Use section. Should let you know what's causing the battery drain. However, if you tend to use light or white wallpaper, leave your phone screen on a lot, and at max brightness, your problem isn't software related

*How did you overcome the Massive OVER HEATING

My rezound is over heats until it shots off sometimes. This over heating isn't normal. over 118 degrees). I don't think there is a fix, might be wrong. but what have yall tried and have you been successful with over coming the heating?
Over 110 is normal for this phone. Mine rarely gets that hot unless streaming stuff on 4g. But I would say 110-115 on heavy 4g use is normal. 122 is max. After that is when it should shut off

the 110 degrees might be wrong. My phone isn't on at the moment so i cannot tell u how hot it is. the heat totally killed my battery, and i had to order a new one.im trying to avoid the heat destroy this new battery. what u think?
110?
There are a skillion threads on heat on these boards.
Your phone will not shut down at 110. Your phone will not shut down at 120. If you are in 1x, your phone will heat. If you are playing a HD game, your phone will heat. If you are in a hot car, your phone will heat.
But your phone will NOT shut down at 110. If your phone really did shut down at that temperature, then RMA it.
Never noticed my phone getting hot. How do you measure it?
newest leaked RUU has fixed this problem. ruu and flash a new rom and not a restore and you will see you phone stay under 100.
I'm running identical setups on 2 phones but one of them gets super hot when charging and also hotter when under the same moderate use.
The newest leak may have fixed it for you, but it hasn't for me. I still struggle with heat. Mine got to 120 surfing the net on wifi in airplane mode just yesterday. I think they have bad batches, and until you get a good one, you will have this issue. This is my third Rezound, and it may be going back as well. I really want to love this phone, but am getting a little tired of trading them in. Hopefully the fourth time is the charm.

I sure would like to contribute to this thread but it would be helpful if someone could answer me and tell me how to measure the temperature, please.
Battery monitor app from the Market will track/display the temps.
This phone does run hot, and the ICS builds are hotter than GB was. I can still overheat mine with prolonged heavy surfing, esp on WiFi, but the latest leak is far better than the preceding ones, at least as far as my phone is concerned.
I didn't do anything. My phone has been in my pocket for about an hour, but setCPU says the current temp is 80.7*F. That seems pretty reasonable.
I stick mine in the freezer

lol mine still easily hits like 105..im not complaining because mine never 'overheats' but the RUU, if anything, makes it run warmer for me.
I am totally stock. Hit about 114.6F in a 75F shady room after playing Temple Run for about 20min and then streaming 45min worth of Youtube via 4G. I was also charging it for about 1/2 the streaming time.
It felt really warm; warmer than I ever felt it. That is waaaay harder than I ever use my phone though so it doesn't bother me.
After wireless tethering for an hour on 4G: 115*F
Still, this doesn't seem warm enough to warrant any concern. It does not seem to ever get this warm during regular usage, and even now it doesn't seem warm enough that I should be worried.
dose the heat from the phone contribute to the limited battery life.?if the official update dont fix this im gonna sell it.
I've never gotten over 114 degrees and I rarely ever get to 110.
Knock on wood.
I have hit over 120, but I was also charging and using WiFi tether.

Now that we have custom kernels
I wanted to see how people are managing their overheating issues. I am on my 6th rezound and I use it as my main GPS. I am sooo sick of the flashing red and green bulb telling me I can fry bacon on my phone.
SO here is what i have...
S-off of course, ruu to latest global , then custom hboot 2.27.
Viper, with dsp 1.0.7 custom kernel . All frequencies and are undervolted by 100 mv ( anything more causes stability issues )
I use incredicontrol for max 1.0 ghz with lagfree governor and bfq
guess what, i am still overheating.
Any more manipulations i can do to prevent walking around with a toaster oven ?
Sorry for resurrecting an old thread, but we have too many of those thread already, and i didn't see any after the source was released.

I hear ya, I have tried just about every combo of rom, kernal, gov, Etc...
Still hit 130 deg.
Maybe we can just use them to sell toast on the streetcorner
I think you just get a good or a bad one, for me all 4 have overheated
Personally I think its BS and about ready to chuck it into the Fire and really watch it Burn!!

[Q] Ungodly Hot

So, tried about 4 different roms, flashed the latest firmware, tried about 3 different kernels & my phone is still getting exceptionally hot a matter of minutes with screen on. Screen off, cool as a cucumber. Screen on, hot as hell. Anybody have any indication as to what would be causing this? I just went to NuSense 6 RC 6.8. Firmware is 1.02.01.0818 & hboot is 1.57. Fully s-off & rooted. Didn't have heating issues with ViperDNA, just the worst battery life I think I've ever had on any of my phones. Any help will be greatly appreciated.

Quite true, but I have mine set to auto brightness, being the fact that I'm moving from various lighting conditions. I've tried different kernels, to no avail.

Did it overheat when stock? Have you checked to see if something is running your CPU in the background?

That's the thing, I never really used it as I bought it on swappa as a replacement to my original (that I dropped & shattered the screen) Once I got it, went s-off & rooted, then VZW update went through & so did the phone (soft-bricked.) So, wiped everything out, installed Viper DNA 4.1.0 & never got hot, just battery life was pathetic (maybe 14 hours, if I was lucky, under light use.) I've tried cpu spying apps (if you can recommend any that I haven't tried, that would great.) So to answer your question: unknown on Stock, no on Viper, just bad battery life, hot on LiquidSmooth, hot on NuSense.
So going back to Viper is out of the question (error during installation.) So I've decided to go back to LiquidSmooth (love the look) & just deal with the heat until I can figure out what's causing the heat. Any recommendations to changing the battery out? I'm not opposed to that option.
I've done more testing & have come to a conclusion that my screen may be going bad. How did I come to this conclusion? Well, there are no rouge apps running in the background, phone itself doesn't get hot (namely the battery), & in long phonecalls with the screen off it's barely warm. Once screen goes on, boom, instant heater in about 5 minutes (and at lowest brightness setting.) Anyone think I'm right? Can a screen that gets hot like this be going bad?
