[Q] Arc S heat?

Hi, i need a little help from arc S owners.
I looking into buying almost brand new white arc s from a friend but i tried the phone a few times and everytime i started scrolling trough menus or some lookingup on market and web (3g) the phone's upper back (around second mic hole) started heating up (just after a few minutes of usage) and stayed warm untill i left it to stand by. Is that normal? Does everyone's s arc S do that? It's like worm, not really hot, but i'm wondering what would happen with heavier usage than just surfing and scrolling around menus?

It's normal as the antenna and CPU are located there.

Thanks for a fast reply.
So just to confirm, your arc does that too right? More or less just bringing it up from standby makes it worm up?

Well, it gets hot fast but I can use it for a few mins without it getting warm/hot, depends on what I'm doing, but if I use 3.5G it heats up extremely fast and can get almost untouchable up there if you stream a video/tv show for 45mins.

Ok, now you are scarying me and sorry if i'm bugging you i just want to make sure before i buy it, it's quite a sum form my standards so i'm cautious.
I don't think i'll be streaming stuff off net a lot and that long, but what about 3d gaming, watching movies from sd card?
Does the heat interfere with daily usage?
Other phones do that to right? Is it that arc is so slim so its more obvious?

Haha, you can still hold it then, it's just hot and still works perfect and I have my Arc for almost 6 months now. But for that you really have to download a lot.
In games it gets hot, but not too hot, depends on how CPU intensive it is.
Playing movies is no problem.
Phones of friends get hot, too and my X10 did the same.

Ok thanks mate! Just one more, how the battery life on stock?

Two days of average use and one day with heavy.

You should buy the Xperia Arc S, I've also bought it a month ago and there are no problems.
The heat doesn't interfere your daily usage and other phones like the SGS2 also do that (not that much, but it's unimportant, because Arc S is also that fast and the heat isn't annoying at all).
And the battery life is quite good, I'm only charging every 24 hours.

Thanks, i got the white arc s and i love it!

It's perfectly normal that a phone generates some heat when being used. The thinner/smaller phone the warmer it will probably get since the heat got less space to spread out on.
The phone should however not get so warm that you cannot hold it in your hand or not use it.
When browsing (WiFi), charging, in long calls, playing games etc. it's normal that the temp. will rise.

will the heat broke the camera hardware someday as it placed at the heating part??

Mine is almost 7 months old and it was untouchable hot 2 times (charging error, reboot fixed it) and gets warm/hot often, but the cam works fine

My arc s also get heat so fast with 3g on... and its untouchable there when it gets hot! i think it will boil water if i put it there

My arcs
My just hot at the top right conner when playing games or charging

I agree to the last post ... but it depends on the used ROM as well. For example: When I use FXP CM10 it's not as hot as when I use LXP CM10.2 ... But even when it's warm/hot it is still stable and usable ... I had only one reboot when I used the phone while I connected it to the charger

Anyone elses Nexus get really hot sometimes?

My phone has a tendancy to get really hot at times. Even in my pocket. Not sure why but its happened on the stock from as well as the 4.0.3 build. Just wondering if its the nature of this beast or if I should consider exchanging for a new one.

I noticed it ran hotter than it should have been my first two days with the phone (I'm LTE). Even on calls. But ever since this weekend, it magically just stopped running hot altogether. I was doing some heavy usage stuff last night and it was barely warm.
Didn't do any changes to it either so it's puzzling. Wish I can give you a better explanation.

Yes, noticed that today, but only when playing games. Any other time it is nice and cool. I suspect the protective casing I got for my GN does not help. I am not using LTE by the way

I was streaming Google Music from LTE, HOT POTATER

Only a little, but my point of comparison is my thunderbolt that would get so hot when in heavy use I'd wonder if it would explode on me

The phone gets hot sometimes..like any other device with any oomph under the hood. My def. warms up alot during some activities.

If you want to experience hot, try this app: https://market.android.com/details?...51bGwsMSwxLDUwMSwiY29tLmludG8uc3RhYmlsaXR5Il0.
Battery reported 47°C after a few minutes.

The radios aren't correct in this phone. 3g and 4g will make it hot as ever. Of you chill on wifi it'll be cool as ice.

Dammmm always the same thing, I thought this was going to fix with this new version of android but I see this problem of overheating continuing, I not understand until we have to deal with this problem, for the love of god any company that corrects this problem.

The only time my phone got seriously hot was watching a two hour netflix movie over mhl. And honestly i was more concerned about the battery temperature. Even gaming my phone gets nice and warm but pales in comparison to the heat output watching that movie on netflix. Of the 33% battery i lost watching it, i think most of that loss was due to heat. Watching a movie on amazon instant video over mhl was comparable to playing a game where heat was concerned. I only lost about 10% battery watching a 2 hour movie then. Also note my gpu is @ 384 mhz and i'm undervolted quite nicely.

Mine got considerably warm until I installed a UV kernel and undervolted quite significantly.
To me it looks like they've..generously volted the CPU in this thing.

I noticed my heat went down also. But i think people concerned about heat should get less powerful phones and be done with it.
Does anybody think sgx543 mp2 in the iphone 4s is cooler? Go be cool then. We are here for the open source android experience, heat and all.

Um do you have any idea how difficult it is to passively cool a multi core processor running at over 1ghz packaged next to radios, batteries, and other misc electronic components. Oh and let's not forget wrapped in a 9mm thin shell with zero venting. Wtf do you expect

man I love my android phone and have had more than 4, but this is a problem and suck at this point in the game, the only thing that I respect the iphone is to control the heating, and they can do that android should be able to equally.....that's my opinion and the only downside that I see android.

Mine gets a little warm occasionally, especially when gaming or streaming netflix, but not enough to be of concern. I had the RAZR before this and it would actually get uncomfortably hot against my face during phone calls, so the Nexus is a welcome change.
I agree with Slowhatch. Passive cooling can only go so far, especially with no vents. Personally, I'm amazed that these devices can stay as cool as they do.

Finally made it to a VzW to play with my next phone (NE2 up on Dec 29th) and noticed this as well. Nexus felt massively hot compared to Rezound and Razr. But I also spent a good amount of time toying with it and letting my fiancée play with it. The Rezound was kinda cool... Razr is as pathetic as its older namesakes.
I don't care though, I'm buying a Nexus even if my pants do burn up.
Tapatalk Pro Sig. Yep, boring.

I'm slightly worried about mine. It gets hot for seemingly no reason (even while browsing the web sometimes).
Maybe I'll do a bit of an undervolt and see how things go.

ya...i too have same problem with my cell

had the first samsung galaxy s and at one point had to have them replace it when overheating ruined the screen. my LTE GNEX heats up I notice when on the phone and ocasionally at other times which does have me worried given my past experience with samsung phone

just in case anyone is interested:
watching an hd mkv using mx video player with HW acceleration on: top right part of the g.nex gets burning hot after 20-30min. (i gues that's where the cpu/gpu is located)
you can decrease this by swiping out all other apps running in background and switching to SW or SW-Fast acceleration, frame rate stays perfectly smooth and voice sync is ok and cpu/gpu temperature remains warm instead of coal hot.

S3 getting hot when playing games and..

Hey gang.
Does everyone's s3 get hot when playing games?
Just trying to figure out if it's normal. It feels hotter than other phones I've owned. And want to know if this is common or if I should return my S3
It's really warm when using data (browsing, YouTube etc.) around 95-105°
But gets hot when playing games. Around 120 -125°
Chime in. Would love some feedback on everyone's S3.

I appreciate fellow S3 owners posting here. Just to put my and everyone else's mind at ease.

Every smartphone I have had gets warm when playing games for over 30min.
I believe this is normal as long as you monitor and don't over clock a lot. Eventually that can kill your hardware.

today for me was the hottest my phone has ever gotten - 105F. it was 95F outside and i had to turn my screen brightness up so i could see, on top of surfing the web and chatting on the phone. someone commented in another thread that our phone can go up to 140F without issue. i dont know if thats true, but there ya have it...oh, i havent played any games yet

Been monitoring temps with system tuner under different stress levels. Playing gta3 I pushed temps to 52°C.
Internet browsing has me around the low 40s. At idle the temp is around 32-35C
My ambient temp in my home is about 73-74 F.
None the less this phone is one hot tamale! Lol

I've only played one game for any extended period of time so far which is Home Run Battle 2 and my GS3 doesn't get hot at all. It runs just slightly warmer than it usually does but it's by far the coolest phone I've eve had.

My phone gets warm as well. The temp is about average just like the rest of you guys so I wouldn't worry. Having a very thin back cover doesn't help either.

Under voting helps with this a TON. I took my voltage for 1.5ghz from 1150mv down to 1025mv and it stays much much cooler under full load. Oh and temps won't break your cpu, too much nanny software on this chip. Even over clocked. Over voltage may though =)

not really

So far I tried playing Final Fantasy 3 on it, definitely very warm, but not hot to touch. Others include Youtube and prolong Web Browsing. Music is fine however. :victory:

The phone gets really warm on stock. The cpu has a temp control feature that if it gets too hot it will slow down. The cpu is made to work up to really high temperatures so I wouldn't worry too much about it.
If you flash to a custom kernel, they are lowering voltages on some of the frequencies and I am noticing an incredible loss of heat. My phone does not get warm anymore, at least no where near stock.

This. Like faux said some of the chips run the same voltage across many frequencies (in my case 1150mv) I was able to lower them into the 850-1050s which is crazy low. Remember power draw goes up exponentially with voltage change.

Is it possible that the American version (dualcore 2gb ram) doesnt get as hot as the international one (quadcore exynos 1gb ram)?
Mine gets pretty hot as well when i play for long times, i guess the main reason why many people are talking about this is that the Chipsets are located directly at the bottom where you would hold your phone while gaming in portrait mode for example. So you can directly feel it and the heat of your hand further warms the phone My Tegra3 tablet gets pretty hot as well in one spot - where the cpu is, but its not a place you normally place your hands, so you wont even notice that it gets warm.
Same thing was with my previous phone the DesireHD. It never got hot on the places where i held it, so you think it wont heat up at all.
In general though: I have some experience with cpu clocking on PCs and overclocking and stuff. It depends a little on the chipset of course but in general temps like 50-70° C are no problem at all for CPUs.
Workaround on SGSIII: Enable power save mode CPU. It reduces the clock to 1ghz (at least on my rom - stock jelly bean polish release), it still runs most games and UI perfectly smooth in jelly bean but it gets considerably less hot.

if i install many apps at once (testing new roms) my phone gets hot

Anyone play it?
Am I the only one that gets random lag spikes and overheating while playing this game for a long while?
I've never experience lag on any game I've played in my gs3 like I do while playing this. I still manage to have fun but sometimes I have runs that are stopped because a random lag spike. Ultimately this game kills my battery both in life and heat.

My gs3 gets really hot whenever I play most games for more than 15 minutes. Really upsets me. I hate holding a hot phone it makes me nervous and let's me know that when I look at my battery stats next it will have dropped 20% in 20 minutes quite unfortunate. Maybe will get better with development but its the same on stock for me

I have a naked GS3 and it never gets hot but when I put it in any case or put on a screen protector it quickly boils. If you are using a case, screen protector even a battery cover sticker on your phone it will cause heat to build up as it now requires multiple layers of material to reach the outside. Take it all off and the heat should be normal again.
P.S. I just played CS Portable for over an hour on multilayer while the phone was plugged in to a car charger and there is very minimal heat. Far better than any other Android phone I have ever owned.

ok so i watched another video about someone else saying he got 29 hours of power on a charge. im still getting about 8 with heavy usage. not rooted yet. is this normal battery life? screen is on 3/4 wifi is always off as is gps.

Wifi uses less power than 3g. 8hrs of screen on time is reasonable at stock imho.

With avg use, and counting that I do sleep 8hrs/day... I have 2 li-ion poly batteries & never tether to a wall... I generally get 24hrs, with about 10% or more remaining. I swap, read a book, until I am sleepy, go to sleep. The battery usually is about 95-97% when I wake up.

I don't think the op said that he/ahe is getting 8 hours of screen time. I think it's 8 hours total and if that's true then that's pretty bad battery life.

Something seems wrong

I have had the phone for a month now and have yet to kill it in under 24 hours (ok fine I got it to die in 23 hours and 36 minutes). I usually get about 1 day and 6 Hours. Of course, I am sleeping for a good portion of that... Typical screen use time is about 3 hours for me (inside that 24 hour phone use time) but I have done as much as 5 Hours of screen time. Im assuming that you could kill the phone faster if you really tried, but i have a hard time believing it would die in 8 hours unless you were doing everything you could to kill it..

ok thank you guys can i ask are you all roooted? im still on the fence about rooting this phone like i have my others. can not being rooted effect battery?

I'm rooted, running UltraLight1.5 with Perseus kernel. Rooting aside a big battery killer is the wireless network locater in Settings/Location Services. That stupid service kills battery with thousands of pointless kernel wakelocks. I used to disable Maps entirely, but that ain't needed.
I leave GPS &WIFI on all the time with screen brightness on auto, power saving turned on on the screen and cpu. 8hrs of screen on time easy...overnight at idle there's minimal eating of battery while I sleep.

my brother got 2 days and 8 hours. he uses wifi when at home. not sure about work. he has a live wallpaper. he is stock rooted.

Obviously heavy usage is relative. I definitely get over 24 hours worth normal use. I'm pretty much on it constantly. I would imagine if you are gaming or watching videos then your battery is going to die much quicker.

Being rooted doesn't give better battery life is just an access for to things you couldn't unlock before like admin rights.
However if you freeze a few apps you don't use and close any apps after your done with them you'll get better results.

Im pretty sure those ppl who get 2 days on their phone barely use this device as far as watching videos, games, n etc. ive seen those screenshots and barely or never is video or gaming usage seen. What's the point in having this beast if not being used but left idle so the honor of the longest lasting battery is displayed for the world to see. Lol smh. Btw 8 to 10hrs for me heavy usage..
