230c sometimes the BGA ICs fall off and I have to open the phone and reball the ICs and flow them back into place

I got my first SGS2 and it was really getting hot especially when streaming movies or playing games etc..i could not touch the back portion where the camera lense was. That phone had a 3g connectivity issue..so i had to return it..anyway while waiting for my usb jig to arrive..i bought another SGS2... using it the same way like my first phone, it never got hot till now..even playing games or streaming movies..it only gets warm and when i checked the battery temp..always showing about 36 to 38 degrees. On first phone, my record temp was 49 degrees and maybe it could have gone higher if i did not shut the phone down and cool it..

Got it to 45C tops, when playing heavy games continuously.

It goes upto 45 for me as well. I felt it very hot just once on the second day after I got it where I feel it went above 45. After that I've been using a cover so I dont notice the heat much and since that its never gone aove 40. Its better if you install some temperature app to monitor. Battery circle is good as it gives the temperature as well as the battery percentage remaining.
The reason it heats up so much is because there is very little gap between the components and the phones body since its very thin so the heat gets transferred directly. But it cools down pretty easily.
Sometimes it could also be because of an app- in my case it was twitter. I login only with Wi-Fi and I have disable data so it kept trying to connect and that heated up the phone. After that experience, I always turn it off after I disconnect from Wi-Fi.

My phone get's VERY hot, will also crash and a yet to be unmentioned thing, is that if I turn it off an hour or so it feels the need to automatically turn itself on again. Anyhow I will be getting a replacement of the phone selling it as brand new and be getting a new different phone.

My phone used to get hot initially when i used to use stock kernels... Then I flashed insecure kernels...one thing I noticed that when I flashed Chainfire's kernel, the phone tries to stay at an optimum cpu frequency even while playing games on it...I tested this using cpu spy... I found the phone rarely used 1200 Mhz frequency but still felt buttery smooth... when the phone constantly stays at 1200 Mhz, then cpu heats up, but when it is at 800 Mhz, it never heated up even with the heaviest usage... and ya, my phone is not under/overclocked

mine doesn't get tooo hot unless i've overclocked it or something, have a go at undervolting it, look at tekrak's overclock guide in android development for advice on that
it should help temperature problems, i hardly get them

I've done the air condition trick after it got too hot twice. But I had a doubt as to whether the sudden heating and cooling will have a damage on the phone and so stopped that. Now I just wait for it to cool down.

I've got it up to 55°, playing order & chaos over wi-fi, max brightness and connected to my charger supply.

Connecting it to the charger itself heats it up a lot so I can imagine what will happen over wifi with heavy gaming

Didn't it damage your phone?

Got this phone just yesterday. Highest temps i've had so far while gaming over WiFi and charging: +39C CPU, +42C battery. Before launching any game i take the phone out of protective case and set CPU to 200-800MHz.
The only problem so far is Pocket Legends that freezes every few minutes. I found the thread about it here on XDA and on official website. This game was the main reason why i bought this phone. Wanted to play it on high-quality, large screen... Sigh

How hot is your Galaxy S2 ?

I was playing a game for about 2 hours, Drag Racing, and suddenly I felt the back of the phone really hot
I took some screen shots and after I continued my game, but the temperature didn't exceed 53 degrees Celsius, not that fahrenheit bull****.

One suggestion to keep things cool is dont play heavy games while charging, Let the phone charge while your asleep, and use it when your not.
This way you wont have to face heat issues(well at least temp wont get very high)

ive had my phone for few days, it gets hotter than any smartphone ive used before, even under heavy browsing while not charging.
I'm planning to get a case and concerned that the phone will fry itself while inside the case..
btw what program are you using in the screenshot to read non-bull temperature values ?

What is the program you are using please?

normal regular use - 35 celc
gaming/heavy use - max i have got is 45 celc
charging without use - 41 celc
charging with use - about 45 again.
id say mine isnt too bad.. i have a case on as well. without the case its about 2 degrees less on average.

program?

The first screen is SystemPanel App - Task Manager and the second is a custom widget from the Elixir app
so... no one with a higher temp? :-D
p.s. no case on mine

Well i would assume that playing a game for 2 hours solid would definitely make the phone hot, given the phone is so thin it feels hotter than say a phone like the HTC HD2.
I play some games but not excessively, i played Brothers in Arms 2 and Lets Golf today about 20 mins each game and the phone didn't feel particulary hot afterwards,in fact since ive had it (around 2 weeks) it hasn't felt particulay hot.

Overheating? Drag racing? Don't drive so fast
Seriously tho, I was under the impression the phone is meant to run quite hot? Not sure exactly how high it goes before shutting down tho...

Its the Software problem. ICS problem only not GB!! t

Which android software you are using? I think its ICS problem. Same problem with my Sony Xperia S.
It was getting hot while playing games. My android tablet on ICS have the same problem but I play same game on
Samsung galaxy S 1 it was GB. It never got hot. 7 to 8 hours. It was never hot. You should use GB for games. Its my
Personal analysis. Hope its true.

its hot man ..... i got i got from a guy on the street and the cops are still looking for it ... i think it's super hot
now moving to on topic :
- the phone heats up a lot , not just the back even the screen . I noticed that it really depends on the game i play. for example if i play "granny smith" or anything similar the heat is ok . If i fire up Batman or other similar games that use grapghics a lot then i have to leave it a few minutes before i can make a call .. cos it feels really hot
i had this problem from the first day . But , i guess it is no problem that it heats up . Other phones do not heat .. it's true but such hardware it's expected to heat up this much

Try KH3 modem. It made my overheating problems go away!

Try flash a rom and then you can boil an egg with it...:laugh:

This happens to me too. Especially on cm10 so the cpu is doing a lot of the graphical rendering thanks to no butter at the moment. Hottest mine got to is 48° after playing World of Goo for an hour. Other than that I've only noticed increased temperatures wge, I go a bit flash mad and flash different things one after another.

I find it's a kernel issue...
when I have a good kernel that works well with the rom I'm running - then it doesn't heat up too much... occasionally it'll get warmish
Use your cheeks (on your face :meh: to test) -=or=- weird as it sounds your lips!! Don't use the back of your fingers, it'll feel warm no matter what!!
I've come close a couple of times to core melt down & had to pull the battery to remedy the situation...

A lot of things can cause this:
- Heavy games
- Bad mobile signal
- Heavy usage of browser
- Charging
Nothing to do with GB or ICS, the problem was the same with both.
Yes, it's the hottest phone I had in many ways.
Didn't you asked for that?
Didn't fry yet... and I doubt it will but it's sometimes uncomfortable.

[Q] Slow quadrant score?

Hi everyone!
Last night I was sitting with a friend of mine and tried to tell him that the Nexus 4 was faster than his Galaxy S3. He wanted to test it out and we both downloaded Quadrant Standard and ran the test...
Let's just say that I had to eat my words. I had a fresh install of CM10.1's latest nightly installed. The strange thing was that I was expecting the CPU to max out at 1500~MHz but it still stated 1100~ whilst the S3 was around 1400Mhz.
I went into the Performance menu and set it to PERFORMANCE but still the score was lower. My friend's S3 also had a custom ROM so was thinking that maybe the extra 1GB of RAM in the N4 may give a higher score.
What happened?

so because the s3 scores higher in quadrant, youre thinking that its a faster phone?

Quadrant scores literally mean nothing. You can't compare scores from different hardware on different versions of android running different rooms.
The s3 is a great all around performer that scores above average in all categories. The Nexus 4 scores higher in some categories (mostly hardware and software) but scores lower in others (camera, speaker)

thermal throttling

The Nexus 4 has got some heavy thermal throttling problems, search for this term on these forums and you'll find plenty of info about it. Basically, the Nexus 4 is the only phone that is unable to keep running at the stated max clock frequenzy for more than ~5-10 minutes, because it would overheat. After a few minutes, it will throttle the performance. This is also the reason it sucks so hard on benchmarks, compared to other phones with exactly the same hardware.

Not at all. I was just wondering what would cause the large discrepancy in the score.

I read a little bit about the throttling but didn't think that it was that prevalent.

check out the benchmarks here when anandtech put the N4 in a freezer. It tops every android phone on almost every test(and it still suffered from thermal throttling ). Any benchmark done for the browser will be slow bc chrome sucks for mobile phones. The AOSP browser will have higher results

It's not necessary to use CPU at full power for graphics tests. The GPU is what is put under stress.

Holy ****. That's incredibly... worrying. Like someone added a .5 to reference volts or something. It really shouldn't get that hot.
But also incredibly nice cause the scores as so tasty. For 2 minutes at a time. Imagine what its doing to the battery as well!

No it isn't .. It doesn't use all the cores all the time for everything..
even if I fire up GTA 3 , straight away it isn't using all the cores, and in fact doesn't use cores 3 and 4 at any time in GTA3 , it isnt throttling here,
The only benchmark iv seen the Nexus 4 throttle on is glbenchmark when ALL the tests are ticked, which is like a 15-20 min test at full load
Dsmboost was correct in the previous post as well , hence why not all the cores are being used when in games.
Can pretty much bet anything that its not throttling in 1 run of quadrant ...

As further evidence, I see no difference in frame rate when limiting my gs2's cpu at 800mhz vs 1.2ghz when playing graphically intense games.

Help, please participate. Do I have a bad hot CPU?

Ok guys I need some help from the community to see if my phone is really defective or not. My issue is, my phone is throttling almost immediately, reguardless of temp (55-63c) range in benchmarks and stress tests, now when I go and force off throttling through intellitemp, when I stress test at above 1.4Ghz, the phone will reboot in a matter of 10 or so seconds. This is after flashing dori kernel 4.4, and I've tried clearing cache/dalvik, reflashing, going back to stock kernel then flashing again, etc...
This is all stock values, with exception of forcing off throttling.
Temps max out around 67c and throttle down at 65c
And it hovers around 45-55c with normal usage. Which seems high to me. But I'm new to high powered cell phones.
So I want everyone who's willing to participate to get the app CpuTemp from play store, it overlays cpu temp while you're doing whatever, enable only the top two options, enable overlay and start on boot.
Then get stability test app and run the first option at top, classic test.
Then report back here with your temp after you do the stress test for about 27 seconds. I hit 66c after 27 seconds.
Curious to see what everyone else hits.
This will at least give us an idea if our phones are operating to spec temp wise and see if I have a faulty hot phone! Please help prevent me from dealing with T-Mo warranty replacement if I don't need to

My temps don't go over 83c while stress testing, max shut down temp should be 120c from what I've read. So I assumed its not a thermal issue. Am I correct?
Hopefully some more people come through and help me figure this out.

Something isn't right for sure, I just set the core voltage for 2.2 to the voltage that 2.8 has and ran a stress test locked on that frequency only and it rebooted still. I'm seriously starting to think I have a bad chip.
It can't possibly need that much voltage.

Hate to be the bearer of bad news but I have been having issues with this phone since I got it. Should have picked up the Note 3 instead. This phone has serious thermal design issues. The instant all four cores come online at 2.3 GHz temp starts rising above 60. Slowly the phone throttles to about 1.3 GHz. It is very noticeable in games, even playing for 5 minutes and the game starts to feel sluggish due to throttling.

Maybe if you try undervolting a litlle, really helps get the temp down.
2265MHs @ 965 mV
oc: 2496MHs @ 1000mV (Stable)

check whats using cpu, enable development settings, then in development settings there is an option that shows whats utilizimg cpu. Could be a process that has gone astray.
usually clean install without recovering apps data does the trick. Dont ever recover system stuff.

From the testing I've been doing this is correct. Its more as if it was designed for the max clocks to be a turbo mode. For quickly taking on small procedures, while sustaining 1.7-1.9ghz for major tasks.

wow, such a grown up and not childish reply.

I starting playing golfstar which works the phone pretty hard. At first I noticed how much better the frame rate was compared to my s4, after about 5mins the frame rate went to crap. I can only assume the phone was throttling due to heat. I never got any warnings though

I dont have this problem at all. Was running antutu benchmark two times in a row yesterday with 100% brightness without auto activated, AND charging, and it reached 36C. And its about 27C in this room.

ya i think im going to the s5 or the nexus 5, it keeps happening, so im done.

Are you only having a problem trying to do a benchmark at high brightness or are you having problems with regular use? I use Lux for autobrightness and it's bright enough for me and I have no issues with over heating.
Also, I wouldn't downgrade to the Nexus 5 if you're giving up on this phone. Not saying it's a bad phone, but it's comparatively a downgrade. A G2 would be a better downgrade than that or side grade to the S5 or M8 or whatever it is the HTC phone is called.

it was during the bench. But i did a battery pull and ran 3 straight benchmarks with no overheating issues. But then i did the no lag trick and tried again with it powering down
So the next best device is the m8 you say?

I'd first suggest you just use the phone and not worry about the benchmarks. Benchmarks are meant to push the system so that could be why you're having problems. With daily use, even with the screen as bright as you have it, you may not notice any other issue. Give it a chance first.
And from reviews I've read, it does sound like the M8 is the next best. I almost considered it, but it's about the same size as the G3 with a smaller screen. Fortunately, I'm loving my G3.

My phone shuts down when reading books on the beach in Turkey. I think the heat sensitiviness is one thing the latest patch should fix , I hope

Mine's never dimmed but it gets warm enough such that it starts throttling back to ~1.6 GHz. Definitely not hot though.

it was during the bench. But i did a battery pull and ran 3 straight benchmarks with no overheating issues. But then i did the no lag trick and tried again with it powering down
So the next best device is the m8 you say?

The no lag trick, is no real trick, it turns off stuff to keep your device save from overheating, so, that's why it turned off afterwards.
I've kept the stock setting and never had any shutdowns or noticed any performance problems at games or dim, it gets warm sometimes at long gaming, but that's it.

Have you tried factory reset from start up screen not settings?

i got a different phone, from a different batch, the phone gets hot still, but not too hot and its not shut down yet. so far so good. great phone

If you are returning a phone because it will shut down during a benchmark, then why did you get the phone in the first place?

You are not alone. Mine can get very hot when playing games (especially when charging), and I have to stop game to cool it down.
The situation gets worse when dual layer case installed. I have to remove the case to cool the phone down.

My phone shuts down when reading books on the beach in Turkey. I think the heat sensitiviness is one thing the latest patch should fix , I hope

I am sure mine does "thermal throttling".
When the phone gets hot, Quadrant goes down to 12,xxx.
When the phone cools down, Quadrant goes back to normal (23,xxx).

sorry, your question does not make sense.
I bought the phone because it had nice specs. i returned the phone because it was apparently defective. My new LG G3 has not overheated to shut down. got a little hot but not bad

I'm still wondering how are NOW the LG G3 are this moment? do they still have overheated issue?
How is the camera in 4k recording? is that fixed?
