Hello,
I just flashed Cronos 1.2 last night, and after overclocking to 1GHz(62vsel), I noticed that my battery felm warm.
This morning the temperature had jumped up to 38C, but is presently at 34C. I used to run around 28C on CM7 and am wondering if these temps are normal? Should I downgrade my O/C to 900MHz?
Thanks in advance!

38C is definitely fine.
When i surf the web using 3G network, it is always 37C+
you can set a tempature profile using setCPU to lower the clock speed if temp. is high
You can edit /system/etc/init.d/10overclock using ROOT Explorer to change the speed to max 900Mhz. Also try to lower the vsel in the 10overclock file, it saves a lot of battery life
Right now, my overclock is set at 1GHz, with a 62 vsel. I have a stable overclock file from FroyoMod 2.6.0, that would save me a lot of battery life and it was clocked at 900MHz, just curious as to what are normal temperatures are, I'm used to sub-30C on normal browsing
I generally try to keep my battery from going any higher than 32 when browsing the 'net, but I did notice that on higher vsels it got hotter. I wouldn't call it dangerous, but remember that the more you're draining the battery, the faster it'll die. I don't mean lose its charge, I mean it just won't hold a charge any more. Lithium Ion batteries are rated for 500 charges, so if you need to charge the phone once a day, you'll be out of a battery in a year and a half.
If it reaches 40+ I would start to worry, though. The difference from 900 MHz at 52 vsel and 1 GHz at 62 vsel doesn't warrant using, in my opinion.
It looks like the spike to 38C was a random spike, because right now it is anywhere from 32-34C, so I think it might have just been one spike that made the phone get really hot!
I also think that the milestone is getting really hot. I think thats kind of annoying
Well right now I have mine at 29, sitting idle with EDGE turned on.
During the day time I've seen it going from 32 to 34.
With HSDPA and Wifi Tether turned on, I've seen it went up to 54.
That is my experience.. and yes 54 is HOT... usually I just turn off tether for a while, until the temp drops to 40+ before I re-tether.
I had my other phone touchscreen spoiled because of the prolonged heat. Bad experience..

Swedroids test
It throttles at 36 C and shuts down at 59 to 60 C.
They should increase the throttle to 45 C and when 45 C is reached make the throttle more aggressive would be a better solution.
What do you guys think?

If it gets to hot people get the yellowing... I would rather run cooler and not worry about it.
Is this throttling effecting real world usage or just benchmarks? Not being sarcastic, asking a question.

Well i dont know, i dont care about benchmarks, just thought about informing what i found.
And increasing the throttle level and making it more aggressive later on was just my opinion.
I would like to see a comparison with the iPhone 5 and Galaxy S III on what temperatures they shut down.

I think that the video was pretty painful to watch! lol WHO on earth would run a phone to death like that?? Hope they have an extended warranty... For real though, I would like to see them bump up the throttling temp a lil but in the real world most users will NEVER experience something like that because that app is meant to run your phone into the ground! I hate that they even make benchmarking apps cause it makes me competitive but I have found that the N4 is FAST as hell so I don't need anything else to prove that to me... Good vid though for the info but lets all step back into reality...
I'm thinking the S4Pro is rated to a higher temperature, and the thermal shutdown is really more for battery health than processor health... Regardless, 11 minutes at 100% load with no real cooling system...
Does the Galaxy S3 also shut down at the same temperature?
12 minutes with the CPU pegged at 100% on all cores with no cooling is impressive, IMHO. Yes it clocked down to 1150MHz but that's plenty fine.
No real world task will come close to pushing the processor that far. I doubt even gaming will task the cores so much that the phone throttles them back.
A lot of modern laptops won't run 12 minutes of solid prime95 before clocking down. This c2d 2.8GHz laptop I'm typing on now will clock down to 800MHz after 15-20 minutes of prime95...but it doesn't throttle at all when doing real world stuff, even compiling or encoding etc.

In my opinion the throttle should engage at 43-45c because at 36c its idle temperatures when the phone i just on stand by.
Ok I fear that's a real problem. What if I want to play a graphic intensive game for a few hours? Expecially on a hot summer day?
Could the phone shut down?

So much for Qualcomm's butter test
In the video description you can find:
"The reason as to why we published this video is because we've never experienced temperatures reaching ~60 degrees C before, nor have we ever experienced a phone shutting itself down after just 12 minutes of continuous full load, nor have we ever experienced such aggressive thermal throttling. It pretty much throttles down instantaneously from 1.5GHz to 1.2 or 1.1GHz during heavy load.
All temperature readings are presented in Celcius.
The Nexus 4 seems to have some issues with heat development. At least if we are to believe our findings. There might of course be a possibility that our unit is faulty. We are however not alone according to the Google Android issue tracker: https://play.google.com/store/apps/details?id=com.into.stability&feature=.... A google search on the matter will also render lots of user reports concerning heat issues.
In comparison the quad core Galaxy S3 (3G) battery sensor reports ~41 degrees after 13 minutes of full load with the screen set to 100% brightness. It does however lower the CPU frequency to 800MHz at times, but mostly run at 1.4GHz. Our IR meter reports about ~34 degrees if we go ahead and measure the hottest spot on the back of the phone (area around the camera lens)."
For me, this is a no-go. I wouldn't buy a phone that shuts down after a few minutes of processor stress testing. Can somebody tell if the same happens with his N4?

Thing is that if you search the web for this problem, you get a lot of hits about people have thermal issues. I hope it just is a defective unit but it seems it is not the case. The S4 pro seems to be generating to much heat and requires too much power. That's why it empty's the 2100 mha battery a bit faster compared to other devices.
Maybe the S4 pro is more suitable for tablets and not phones.

Very few applications will use 4 cores. Hell, most don't even use 2 cores by default. So the chances of you maxing out all 4 cores in routine usage isn't very likely. The extra cores typically benefit smartphones when one process is utilizing a core already, a different process just gets thrown over to a different core so it doesn't have to wait for CPU cycles. Most smartphone use is "burst-y" so this helps end-users out quite a bit.
99.9 % its not the S4 Pro`s fault, just the lame battery from LG. I mean WTF after 15 secs it clocks down !!!!
Yeah, thats weird. But I could live with it, expecially when the phone runs buttersmooth. But if the phone shuts down after a few minutes of processor intensive tasks that's a big problem. I know that barely any app is using 4 cores simultanously, but what happens if you stress-test only one core? Does the phone also shut down?
This doesnt seem that bad, you're stressing it pretty hard which wont ever be done in real word conditions, for example take intel burn test, most people find this stresses the chip to temperatures 15C+ over any possible real word tests/usage.
You say the SGS3 throttles to 800Mhz at some points well thats pretty poor is it not? Clock for clock the s4 pro is superior and so clocking in over 300Mhz faster when throttled its pretty good id say. If you're comparing the S4 vs the S4 pro (US SGS3) then its pretty hard to say the battery sucks when its got more power! Of course it will run hotter haha.
I think they could put back the throttling limits a bit though, I think it maybe a battery issue more than anything though so maybe its a fault... Please test it by stressing a high end game for an hour or so tracking the temps and clock speed, that would be a much better indication.
edit: Seen your reply before me, It wont shut down like that in the real world! If you stress test only one core I can assure you that it will run MUCH cooler, you are essentially testing 2x the amount in the s4 Pro than you are in the dual core varient, in these stress tests it works pretty much 110% each core, in the realworld there will be idle times and switching between cores handling different threads, lots of variences that should mean it would be ALOT cooler all the time even if using all 4.

1 core likely won't generate as much heat, and not to mention the whole point of the cores is to distribute load and operate at max efficiency rather than less cores at max.
I understand that some people have issue with the throttling, but until people report that they can't play x and y after z minutes it is a non issue. It may have to do with the glass, maybe LG battery. It is possible the throttle is there to preserve the higher recharge cycles LG Chem batteries have.
Unless it actually ruins an app experience, on stock rom and kernel, it is not an issue. If someone would rather pay 400 more to boost their bench by 5% that's up to them.

Mhmm, I guess it won't be a problem in real world usage. Nevertheless it's quite weird that the phone heats up that much AND THEN SHUTS DOWN, expecially in comparison to other phones like the SGS3, where this problem doesn't occur.
But yes, I didn't hear any complaints about critical-heat-shutdowns in real world usage, so maybe I'm just overreacting. But at the moment it's winter in USA and Europe, so let's see how the phone performs in summer heat
My old HTC Desire often overheats and shuts down on hot summer days when I'm using GPS or playing games, so I just hope my next phone won't have this problem

Mine has been shutting down due to overheating at least once a day. I've just exchanged it so will see how that is.
Worryingly, I will often be doing nothing other than web browsing or similar which should not stress the CPU
What's the lowest has anyone been able to under volt the Moto X? I just tried -75 mV set globally and I haven't had any bad experiences so far.
My question is why? Not many reports of overheating on the X and that's all undervolting is good for?
You won't notice any battery life increase. That's a nasty myth.
I'm at -125mv for 384 and -100mv for 486. Then 50 or 75 for the remainder. Have noticed absolutely no battery life difference. I'd be careful with -75 with overclocked frequencies if you're using faux ultimate kernel. I can't do more than-25mv at 1.944.

your statement is a myth. it doesn't improve dramatically but nonetheless it helps. when I undervolt I am more looking for my CPU to stay cooler these add longevity and not letting the battery heat up as much. out of all my undervolted phones, there was a noticeable improvement on my galaxy nexus with battery life and heat. my note3 isn't dramatic, but I do notice my phone rarely gets above warm now. and depending on the bin of your chip, your undervolt can have more desirable effects if you have a great bin. my moto x had a 3 out 4 bin but I never flashed a custom kernel. my HTC one m8 has a bin of 9 out of 16. decent. but the guys who 13 and 15 bins should get great undervolt. undervolting is worth it. adds longevity to the battery itself the less it heats up.

Pretty sure I mentioned it keeps heat down.
And I could have posted a huge long reply the first time....but "generally", undervolting to improve battery life is barking up the wrong tree. YES it should have minor improvement....but not anywhere near what some people hope when they do it.
At best you may gain a couple total hours and maybe 20, 30 minutes screen time.....if you tweak other kernel settings as well??? Hopefully we can agree on that. And to me, the possible instability from guys pushing the limits is not at all worth those small battery savings.
As far as longevity of the battery.....all I know is my oldest device is 3 years old...and battery life is as good as it was when I got it. But sure, it might help.
Heavy gamers or anyone with heat issues....yes....undervolting will help.
Guys with "bad" battery life.....you will at best go from "bad" to "still pretty bad".
Hi there
Just bought my z3 compact a couple days ago, and have not been getting the battery life everyone is so excited about. I just ran antutu and hit (what I think) is a ridiculous score of 44012....
BUT my battery life is around 4 hours screen on time. Are the two related? I'm debating taking it back to sony as I'm really not getting what I expected out of the phone. Battery life is more important to me than crazy benchmarks.
Any tips?

Mine's 44,980 - while battery life is around 2 days with 7hrs screen on time. How did that happen? Just simple texting, music playing, a bit of picture taking, viewing pictures, minimal usage for short.

And what do these benchmark scores tell you? They don't tell me anything, it's just a test there is nothing scientific about it.
As for the battery life, try and see if "Android System" has a high usage, if that's the case then it's very likely that one or more apps are in the background using "a lot" of resources.
The chances are small that there is something wrong with your unit, most of the time it's just a matter of tweaking.
I'd also check your signal strength in your area or areas that you typically are. I've noticed that in low spotty signal areas, my battery drops at a fast rate since it's hunting for a signal whereas in a strong area, my battery life and screen-on time is fantastic. The bars won't actually tell you anything...it's best to look at the dB rating to be sure.
