[Q] Heat problems?

Alright guys so today is the first time I've had this problem. I'm running warm z twopointtwo 4/7 nightly with chads 12/23. For some odd reason today my phone has been overheating. Now I wasn't able to get an exact temperature read but my guess is somewhere around "way too effing hot" degrees Fahrenheit. I say this because my phone actually got so warm today I almost couldn't touch the screen. I was seriously expecting thermonuclear meltdown! I pulled my battery and let it cool off and all was fine but still it worries me. I wasn't even doing any intense processing. I was only using the xda app and reading some threads. Throughout the day it hasn't got quite that hot but its been running noticeably warmer than usual. My battery also seems to be dieing slightly faster than usual. Now my phone is a certified refurbished less than a month old so I can't imagine this being a matter of my battery starting to die.....so anyone have any input on what could be causing this? Could it be Rom if kernel related?

I've tried that rom/kernel combo and it worked for me. Are you using a non OEM battery?
Sent from my ADR6300 using XDA App

Nope I have the original battery still in it and everything....I mean it works beautifully outside of a few occasional hiccups here and there but nothing that isn't to be expected.....but the heat problem never happened to me before.....I mean trust me I used to have a crazy overclocked Eris that loved to get hot but never this hot. And I haven't even overclocked my dinc yet....its just kinda odd it was a one time thing but it was almost too hot to touch. It spooked me I legitimately feel like I was very close to processor meltdown.....

Well you are using a "warm" ROM
Just messing with you. I'm running Warm-Z too but Chad's 12/23 kernel won't boot for me so I usually use Lou's #4 or #8, and with them I don't feel heat issues unless I'm charging. I'd say switch kernels. As long as it's a Sense kernel.

Well like I've never flashed kernels before....I'm sure I could figure it out....but none the less this isn't a frequent problem.....that's the only time its happened. I was actually in an area that was in and out of service though.....does bouncing around in service while trying to use 3g require a lot of processing? I can't imagine it would....mebbe the heat came from my cell receiver 0.o

Yeah looking for a signal is apparently pretty battery draining. Still not really sure about the heat issue though.
Sent from my ADR6300 using XDA App

Well I mean if its battery draining that would mean more current through the phone for the battery to drain more rapidly. More current translates into heat in any application. But still the level of heat that was coming out of it was crazy. And I could actually watch my battery decrease fast as hell

Well, I'll give you the link to Lou's #4, and that's a pretty basic kernel. Really it's like flashing a ROM. You go inside your recovery, and ONLY wipe CACHE and Dalvik-Cache. Then flash the Kernel's zip. Then reboot!
NANDROID BACKUP! Don't forget!

What are the real advantages of me flashing this kernel over my current one? Like I don't think it'll help the problems with heat. I'm still interested in that on a side note though. Does it have havs? Cause I hate the fact that I lose ten percent in five minutes after unplug

Some kernels are just better for your phone, and some aren't. I took the time to find a kernel with HAVS that I've used in the past.
http://www.ziggy471.com/downloads/Ziggy471Kernel-INC-update_signed.zip
This should work fine. Ziggy's a pro.

Will that be compatible with warm z? Like I said I'm not familiar with which roms work with which kernels? And while were at it what the eff is bfs? I think I know what the acronym stands for though I'm not sure.....but I have no idea what bfs and cfs are.

So back to topic with this thread....anyone think that my judgement is right with rating the heat was due to he battery drain occurring due to signal jumping?
Sent from my Incredible using XDA App

I think it could be the cause of the battery drain but it doesn't seem like it should cause overheating although I could be wrong. Have you had the issue since then or was it just when you were having trouble getting a signal? BFS-Brain **** Scheduler. Linux stuff.

Possibly. Let me explain.
I'm currently running rooted 2.2 and if mine searched for signal, battery gets warm.....really warm. I flashed the radio to 11.19 (Evo) and so far, knocking on wood, my signal search issue has gone away and GPS seems to lock on instantly. I'm also using the 1800 battery from htcexpress dot com.
The only other time my phone got so hot that the amber light started flashing was in the car, charging, running GPS and streaming music at the same time. Battery temp according to my a battery app was 128 degrees F.

128 f isn't too bad....my Orange light didn't even blink that's the thing and i didn't have an app to tell me the exact temp. However I know that if through the entire case my phone is almost too hot to hold then its probably pretty close to processor melt....and that's another good point.....wtf didn't my light blink? It should have but didn't.....hmmm.....but none the less @k_nive if you agree about signal drop causing battery drain then wouldn't my above post make sense? Yanno, more battery drain = more current and more current = more generated heat due to small energy loss through the wires because of total conservation of energy without the phone following total conservation principles? Aka the phone isn't efficient enough to use all the energy supplied to it so it gives off any excess in the form of heat? And thanks about the bfs info!
Sent from my Incredible using XDA App

And on a side note. I read up on bfs. I get it....kinda. I understand the point but what scheduler is used in chads 12/23? And what are the real advantages if bfs for us Android users over any other scheduler?
Sent from my Incredible using XDA App

It does make sense I suppose. Its just something I haven't run into before so its hard to say for sure one way or the other but the increased battery drain could definitely result in more heat especially if you were using GPS or streaming music at the time.
Perhaps your phone didn't hit the temperature that triggers the flashing led? The phone can feel pretty warm without actually being too hot. I would get a battery widget that lets you monitor temp that way you have a more accurate picture of what's going on. As far as Chad's 12/23 kernel, I think it uses cfs as opposed to bfs but I'm not sure, I'd have to check the thread. As I understand it bfs ramps up the processor more for specific apps/processes while cfs is a more balanced scheduler. I don't know much about the differences so feel free to jump in and clarify things!
Sent from my ADR6300 using XDA App

Grrr.....so I thought that the battery temp problem was gone but Damn it if it ain't acting up again.....this time even more odd....the phone was not nearly as hot to the touch and yet my led started blinking the too hot code at me.....so wtf? Like before I almost melt the effing board and I don't get a single blink. This time its slightly warm and I start blinking. My phones losing its mind. I just got juice defender and a battery monitor widget to try and figure out wtf is up.....any more input very welcome!

Reboot caused a massive battery drop?

I'm currently running gummy nex 0.7.0 and Franco's 14.4 nightly. I have no undervolt settings and currently running a 350min 920max conservative hot plug on setup. I sent a text early today and my phone rebooted pretty quickly. I didn't really think anything of it until I checked my battery an hour or so later. It dropped quite a bit during the reboot. I was wondering if anyone could give me some insight into what happened here? Thanks

Ive seen this before and likely due to the fuel gauge reads voltage only rather than coulomb counting. Unfortunately we dont have access to the exact calculation used.

Phone feeling hot

Hey guys, I had my phone for no more than an hour. Rooted and flashed cm10. Phone seems to get warm like 100 degrees f. And that's not using data or WiFi.
I had stock on for a little and noticed the same thing, is my phone jacked or is this normal? I have warranty so if none of you guys experience this I'll take it in. I just don't think it's too healthy for the device...

My phone gets pretty hot sometimes too, but only during heavy usage and multitasking. If you're finding that it's heating up when you're just browsing the web or installing apps, try using another kernel. I recommend Lean Kernel with CM10

Im tempted to take alluminum foil and place the shiny side facing away from the device under neath the battery cover to attempt to wick away the heat -.-

Yea its normal. Let's not forget the back cover is really thin compared to other phones. To me it makes it seem a lot hotter than it really is.

My s2 barely gets hot :/ and thats with no back cover on just a case. but the battery temps are much lower as well on the S2. usually around upper 70s to lower 80s degrees farenheit under normal load.

yeah
my phone does the same it sometimes does the same it gets hot on the bottom back part

Personally I believe it can be rom/kernel related too. Usually it doesn't get really warm for me except under load. But with the latest leak, if im using it at all, it just stays warm. When I was first using it this morn it actually got pretty hot and when charging got even hotter. I let it cool and hasn't been that hot since.

Mine use to get a lil warm too under heavy usage,until i flashed Faux kernel(<<THIS KERNEL SUPPORT UNDERVOLTING) on sonic Gs3 rom & then i used system tuner to undervolt cpu further(yes undervolt not underclock) although i am running at default clock speed with conservative & cfq settings.Since then my phone runs pretty cool even on heavy usage.I heard the default voltage are sometimes higher than what is needed which may increase phone temperature faster,My battery life is even better now than it already was on Gs3 rom, KEEP IN MIND YOU MUST RUN A CPU STRESSED TEST IN THE SET CPU APP WHEN YOU CHANGE YOUR PHONE VOLTAGE SETTING TO MAKE SURE THERE IS NO ERROR,RANDOM REBOOTS,BOOT LOOP,LAG OR JUST A LIL SLUGGISHNESS BECAUSE YOU UNDERVOLT TOO LOW & KEEP IN MIND NOT ALL CHIPS ARE CREATED EQUAL,So my settings may only be stable of my phone,you may have to take that risk & experiment around.
I attached screenshots of my personal undervolt in system tuner & also a screenshot of default voltage of I9300 variant but i figure.
check the option to use settings on boot in System tuner or you will have to keep setting it on each reboot

Well in my life of hacking phones, under/overvolting seriously reduces life of the CPU.. i dont quite feel comfortable undervolting my brand new galaxy s3. lol. Unless someone can provide scientific evidence to undervolting not causeing long term harm to my CPU.

No reason to undervolt or overclock this hardware. Overclocking became irrelevant when dual cores came out. Undervolting was never relevant. People do it because they like to play around with their hardware, which I understand, though I've always been more interested in software myself.

What are you doing when the phone gets warm?

Mine seems to get hot as the battery gets low (not even on the charger).

Simply moving files around.
But after a two hour phone call while being plugged in I'm only at 93 degrees. So that's not too shabby

Juice Defender - Should I keep using it?

So over in a Development thread I mentioned that I use Juice Defender Ultimate still, I got some heat for it because it's old.
What's new that I should be using instead? Running CM10 11/30 Nightly that I v6 Supercharged (Die-Hard, so I don't think Tasker will work).
I don't need anything to sync or notify me when it's in my pocket, just calls/texts via radio. I also already use CPU Sleeper and it's locked in memory via v6 bulletproof.
My goal is to make the most out of my battery.

not sure exactly. i used to use green power battery. these data killing apps used to work miracles on gb and froyo. but nowadays i think the main battery killers are the hefty processors. i now focus on kernels and governors and whatnot to save battery. i think killing data will help if it stays off most frequently. when you have the settings to turn on data as soon as the screen turns on, the device is toggling data and constantly searching for signal, maybe even killing more battery than saving.. idk thats just my opinion. and on the other hand.. if your not really using your phone so much i think it would save more in the long run. i would just test it yourself and see what works

Only thing that will improve the battery is a new phone .
I've tried everything. The best result has been ditching AOSP and going back to TW. It might not be fancy schmancy, but it functions and has marginally better battery life (at least in my experience).
Good luck on your quest. I'll probably keep my eye on this thread to see if there are any new suggestions (but not very optimistic).

I unistalled JD and set a CPU profile to reduce clock speed on lock, testing for wakelocks now as well.
Anyone know best governor/scheduler combo for battery on CM10 while still keeping it buttery? Im using OnDemand/Deadline for a few minutes and it has not dropped yet.

Sorry but no one can say for sure whats a rock solid combo. I suggest you try them all like I have to see what works best for you. After trying everything I came back to Ondemand and felt it gave me the best results but thats me.
Good app to try is Llama and its free and does all JD stuff and more

to add, regardless of what kernel i use sometimes the processor will climb to unnecessarily high frequencies when the screen is off. to tame it a little more use setcpu and enable profiles. my profile, when the screen is off, is min 384 max 540 and conservative/noop. then when the screen wakes, interactive/noop 384/1512. but im sure most of you already know this. cpu sleeper will do the trick too. beware of wake lag

I no longer use Juice Defender and, for me and my set up, JD did not have noticeable impact.
Nor did more complex strategies using Llama.
The ROMs, governors, CPU settings, and tweaks seem to be where it's at.

I have found that to be the case with every such app I've tried. The best results I've always had have come from removing apps that I don't need or use. I can get thru a full 8 hr shift, so I'm happy.

[Q] what is your Galaxy s3 average temperature

My Galaxy s3 gets hot
My Normal Temprerature is 90 Fahrenheit
this is normal?
i´m only turned on a wifi, or watch a movie on youtube and my phone is already hot
and with the 4g turned on is more hot around 100 Fahrenheint
i have the t-mobile version. android 4.1.1 jelly bean stock rom

Yeah mine gets pretty hot too... I've seen it hit 105. Very bad for the battery :/
Have you checked for rogue processes? Get GSAM Battery Monitor or Watchdog Lite and see if anything is consuming a lot of CPU cycles.
Also, try CPU Sleeper - it shuts one of the cores off when the phone goes to sleep which gives huge battery savings.

I wouldn't do all that doing something that it wasn't intended to be, shutting down a core. Android does a good job with all that, if it gets really really hot
Buy a new battery or better yet start from scratch see if you get it stock. My s3 never been really hot, and I know what hot is coming from the g2x and the first galaxy now those phones will burn you.

The G2x was nothing compared to the Sensation! OUCH!
And it only shuts a core off when its asleep. You can uninstall the app and it reverts so no harm there.
I have a second battery and it runs on the hot side side as well. My roommate has a white GS3 and I have a titanium GS3 and his battery lasts a hell of a lot longer than mine. It may just be defective. I couldn't get his past 90 degrees.

My battery is running 83/84 degrees, but then I recently changed to a 3200 which fits the original compartment.

How much on screen do you get with that battery and do you have a link? Also, is it NFC enabled? I don't need NFC just curious.

Mine was at about 95-98F when I was tethering and stayed pretty constant. The phone was a bit warm, but not worryingly so (it's gotten hotter).
Honestly, I don't think it's a big deal these temperatures seem within normal parameters.

I guess for me the fact the screen gets so hot is what bothers me... and the heat on the back, it goes through my Incipio case (both the rubber and the plastic) and its hot at the bottom of the phone... the temp readings are battery only since it seems the processor doesn't have a temperature monitor - that or none of the kernels support it.

galaxy s3 high temp
10 mins of subway surfers and my s3 gets to 107-110 . Is this normal. I have hard reset the device and running on jelly beans 4.1.2 with minimum applications loaded. Normal temprature of the device when idle is 89 to 95. Only the bottom half of the screen gets hot. Took it to the service center they did nothing but reformat it.
