Hey guys, i dont know if this has been already posted or if anyone else has noticed , some how...my cpu in Xperia s underclocks to 800 MHz by itself , after some heavy usage like gaming (till it gets a little bit hot i guess , maybe its some protective measure?? ) , and i notice a sudden lag spike after playing several minutes or so..when i check the cpu usage (overclocking options in xzx2 ), it shows 824 Mhz, and this happens all too often, before i thought the lag was caused by the RAM(because of near full memory) , and anyway, i just wanna know, if this is like a protective feature or its something serious ?? ....thanks in advance for any help... and if this is already been posted somewhere else, then, gladly remove my post !!
It's nothing strange. It's named throttling. It turning on automatically to avoid burning your CPU.

Thanks for the reply, Vaith... !! now i know...now google searching throttling to understand a bit more !! thanks again

Can someone please tell me what is considered "normal"?
Mine runs at about 55 constantly, is this dangerous?
Hi,
http://forum.xda-developers.com/showthread.php?t=1557494&highlight=cpu+temp
For example,there is another threads...
55°C is not dangerous and I doubt it runs constantly at 55°C,in sleep?when your browse on the net?when you watch a movie?or just when you naviguate in settings?
So,normal if you have this CPU temp while browsing or whatching a video,not very normal if your just naviguate in settings since 10 mins... (according to the CPU freq?) or if your phone is in sleep since 10 mins (if you do not download anything)->wake up and you see 55°C...
While it is charging?
The CPU temp limit is at 64°C (if you don't modify it),above thermal throttling,reboot...
And it's with stock kernel?custom kernel (CPU freq?voltage?),what are you doing exactly with your phone?

Thanks for the response mate.
I flashed Franco M3 last night and was admittidly browsing a lot before I went to bed and this morning.
Looking at it now where its been sat on my desk at work for a while its hovering around 35.
I suppose I was just looking for a little assurance my phone isnt going to break into a ball of flames suddenly!!!
Again appreciate the response mate, Thanks

Ok,for me no problem with your CPU temp,normal

In sleep,for example since 10 mins?without touching it?
Mine in sleep is at 22°C in my home (current ambient temperature about...24°C).
In extreme use (for example during a bench ) go to about 86°C...
In browsing about 55-56°C.
In light use (setting my home screen for example) about 40°C.
For example with System Tuner pro you can follow in real time your CPU temp (with graph).
Running at 1.42Ghz actually.
And in normal use I settled my CPU temp limit to 75°C (stock is 64°C),I feel that by increasing the CPU temp limit the phone heats a little less.

This makes me feel better!! im nowhere near that!!!
Always wonder on these forums and dont take this the wrong way but is their any other point than upping your benchmark by overclocking.
Do you have any noticeable difference in performance thats worth the loss in battery.
Thanks again

I'm just curious because what you said confuses me lol but, how exactly would INCREASING temp limit make the phone get hot less?
I don't know much about how that works (the nitty gritty details) but that seems kinda Counterintuitive?

Hi,
I do not know any more ,like I said "I feel"...
At the same CPU freq and about the same use I feel with a higher CPU temp limit the CPU heats less...that's what I thought noticed when I monitor the temperature evolution in System Tuner...Why?,Placebo?Not exactly the same condition?I do not look exactly at the same times (after a high load) compared to the stock CPU temp limit?...I don't know much...
I tried to reproduce the same conditions for both CPU temp limit,and I think I noticied this...But it's not "scientific" nor proven...
I may be an explanation in French but I can not do the same in English even with Google Translation...,too hard for me
And I am not a engineer in processor and I do not have large knowledge in this...And maybe,certainly,my explanation is crap

Re,
Yes there is a performance improvement it depends in what...
Some apps loads faster,my launcher is smoother (Apex),scrolling is better,etc...
Some people do not notice the other yes...
Even withe the "better" kernel,the more you overclock the more your battery life decreases,but it also depends of the voltage,governor and what you do with your phone...
If I run 15 benchs at 1.65Ghz for stability test (or for to show that I have a big **** LOL )...Bye bye the battery...

Lol thanks
I was just wondering if it was something that was proven
Thanks for explanation.
I'll have to check for myself sometime I guess
I have Acro S and I noticed that the CPU goes to 810 mHz automatically while it heating, e.g. while playing game, benchmarking, or even I use it regularly... Anyone here has a tweak or trick to disable that??

It would not be wise to bypass the cpu over heat protection.
If you have a case on you can see if taking it off helps.
Also with cpu editor you can force both cores to be used

Yea, I don't suggest playing with CPU settings, my friend burnt his ARC trying to play GTA 3 at max so don't do it : (

CPU editor only forces both cores on at all times. If the phone gets to hot it will still reduce frequency to lower temp.
2 cores at a lower temp is still faster than 1.
I am not talking about overclocking the CPU, that can definitely cause damage.

Yes I got it, sorry for misunderstanding

when i went home a while ago i charged my phone because of the low battery. and after like 10minutes of charging my phone is really really hot.
51 degrees Celsius as i remembered. until now i don't know what's the problem. my phone overheats when i turn it on and also while charging.
help me guys i don't know what's happening on my phone :\
Sorry for my english. (my 3rd language)
There is a app that is causing the problem, you need to find it and delete it

Overheat during charging is normal, Also overheat can come if you use lot of procesor power ie intensive 3D games (subway surfer,minions rush, and we will not talk about asphalt, dungeon hunter etc) small games but is very intensive on impact of proc.

Well it seems i only have this problem when im on a OC kernel, no heat when charging, and some when gaming
Weird, do you get ths?

Well that depends how your proc is set.
Noop, deadline, on demand.. They all act dif.
Your max mhz maybe is 1.7 or even more, but current maybe a way lower then on stock kernel because of difrent mods and handling.

Possible way of resolving the problem
Hey mate! I've seen this problem before, and mostly it's because you installed a rom wrong. Try installing the rom again via cwm or twrp, and do an absolute FULL WIPE... format the system, data, cache, delete cache, delete dalvik cache etc and make sure you install the rom properly, that way you shouldn't have this problem anymore hope it works! Come back with feedback

it may be device specific
i have 2 Xperia S, and One Heats up when charging, my other doesnt,
-XS 01 no heating issues at all (max 1836MHz Clock)
-XS 02 Charging heat, Heat issue even when not overclocked, youtube Heating issues, (weird), Max 1728MHz Clock
Other info
Both Devices Use SAME ROM And kernel,Both Devices Were purchased from same place,
XS 01 is Older then XS 02, by 4 months
Try reducing Max frequency using Kernel Tuner.. And use different governors.. Like Ondemand for CPU0 and Conservative for CPU1.. This combination has made my phone stay cooler enough even after half hour of gaming.. Even with Asphalt8 and NFSMW.. And lower your Max Freq to 1.4 or 1.2.. 1.3 will be same as 1.5.. I mean in terms of heating..
my phone have several issues but this heating problem worries me the most..
when im not touching the phone (placed on the table with display on but on lock screen) it is 35C to 38C
when i take it in hand nd unlock and even if i do nothing it rises and reaches 42-45C
when i use apps like gmail, maps, or sms the temprature is around 45-48C
when i play small games it goes between 50-60C
but the most worrying part is when i play heavy games.. the temprature goes above 60C and stabilizes at 65C.. aont once in a while it reaches 68C but comes down sooner
when i run benchmarking apps. the temprature went 70C and even reached 72C twice... will the device can handle such temprtures?
i know most of the processors are made to handle not more than 70C.. so im doubting this heat might burn my phone internals..
is it like this for all snapdragon 615 phones? or will it b fixed if they update to lollipop which is best suited for 64 bit processors?
or should i return the phone ( i have 6 days ) coz its defective??
please give me a reasonable reply some1.. i tried all forums and no reply.. please help me... i dont wanna regret buying this phone in the mean time i dont wanna regret returning this phone either so kindly help me
Please check the battery stat, and see which one is using more, I think You have mediaserver issue, If mediaserver is the highest (above 30%)
then find a fix for it, It is a bug in kitkat

already went through it.. no media server issue for me... its due to some other issue i think..
im getting same issue but my load temperature is around 55-60.
i emailed it to yu customer care.they say its normal to heatup during games and internet bwosing :/

Hi Kartik00 ,
Did your issue got fixed? Heating problem got solved ?
It is not a problem!
It is actually OK. Most of the phones give battery temperature as CPU temperature as they do not have a heat sensor integrated with the CPU.
But for yureka it is different. I mean yureka is special one. It has a heat sensor integrated with CPU. CPU can heat up to 90°c that is normal. But when battery starts to heat up, there is a issue there. Our yureka is fine. :good:
Download CPUz it will give you a pure idea of this

yh thats right.. i realized it after asking around abt other ppl who owns 8core phones its not even a ISSUE.. also after cm12 update my phone doesnt heat much.. hot pluging isnt effective yet though but 2cores (from the performance cores not the power save ones) does goes to sleep when we set it to powersave mode
rollback the update to stock ROM (4.4)
Lollipop is awesome.BT the heating issue is still tr.The CPU governor s are not adjustable in lollipop. BT in kitkat we can adjust it.
In lollipop the CPU always at 950hz (min).so it heats more.

I guess its not just software issue but also a design flaw made by CoolPad. They cover the main processor chip and eMMC chip with aluminum cover. I know this cover is used to prevent dust to get in and static electricity, but it also cause heating problem. Moreover, they place the LCD on top of it. So if you want to get rid the heating problem, don't buy YU, but buy MI 4i instead. If you don't use the phone, the phone temperature will stay at 45-50 degree.
U r suggesting different phone as a solution? & that too atleast 4k costlier one
Hi guys i just got an Xperia ZL C6502 months ago and its a big headache im telling you the cellphone is great but whats really happening
The problem is that in heavy use the Snapdragon S Pro 600 Quad to 1.5ghz comes over 65°c or 149°F wich is absolute damn high so what? it drains the battery from 100% to 0% in around 2 or 3 hours and the cellphone is hot as hell, and not only in games, using apps like Whatsapp, Facebook, etc too.
When im not using it it drains normal ammount of battery like 2 or 3% per hour but when i use it a little while at least it drains 10% of it and im like charging it 2 or 3 times per day.
It has the lastest version of Android supported by it wich is 5.1.1 and rooted by Kingroot App i thougth that rooting it i was able to change the CPU frequencys but here comes the problem, i tried a lot of apps and no one seems to result, my intention was to clock it to 384 thath it seems to be the minimum it tolerates and 809 to maximum to reduce the battery consumption and the CPU heat but when i clock it or push the "apply this settings at startup" the clocks are set to 1512mhz minimum and maximum.
My question is, why this is happening and if there is a solution to my problem.
Sorry for my bad english im spanish and thanks by the way
Anyone?
Hello, first of all the right processor of this device is the Snapdrangon s4 pro (APQ8064).
Related to your problem I think you could try installing another CPU control app, there is one I've used before and is on the playstore "No-frills CPU control". Install it and change the CPU governor to "conservative" or try others... Hope this is helpful for you.
PD: I'm Mexican and speak Spanish also, send me a Personal Message if you want, I think I could help you
