high battery heat !

when i listen music for about 30 mins + and running some programs such as adobe reader or opera, i can feel a warm in my hands from the battery. actually its more like to be said a relatively high heat felt by my hands !?
is this high battery heat normal? i mean for an everyday usage.
tnx in advance
Note: i did search but didnt find anything about LEO battery heating.

The battery can sometimes get quite warm, but it should never be hot. If it heats up to much you should probably get it looked at.
The battery in the HD was a lot worse than this. I think there may have been some issues, but HTC have worked on it. Thankfully, I don't know of any HTC phones exploding anywhere yet! lol

mine gets hot as well some times especially when I use igo in my car and charge the phone at the same time but also when playing a game etc.. but I read in the manual that this is normal... although I believe heat to an extent that can burn your hand its not normal.... mine never got that hold
just my 2 cents

Hello,
If you are using something like Opera, coupled with a number of applications that are cpu intensive, then you are going to get high battery drain which equals high heat output. Some of the heat will be coming off the cpu as well but the end result is the same.
The problem is worse if you are using wifi and/or gprs and you are in a low signal area, which means that the device and the battery need to work even harder to serve your needs.
If this happens again then check your location relative to wifi and gprs and/or reduce the number of intensive applications you have running at the same time.
If this fails then you may have a fault; however I think one or all of the factors mentioned above are linked to your issue.

ok tnx for replay guys...i accept this as normal situation, and yes i definety like to use igo8...and really its soo nice to have pda such LEO that can easily open and run several such programs!

heating issues

got my arc a few days back...apart from suffering from poor battery issues, I have noticed that when I play games on the arc, the top part around the camera starts heating up..
I observed it first when I was playing homerun battle with the charger plugged it..so I thought perhaps its because of playing while charging..
however, even after removing the charger and playing games, the heating continues..in fact the temp indicator on battery indicator shows temps of early to mid 30 C (86F) while playing games (I have not dared to let it go beyond tht)....while on idle it overs around early to mid 20C
is this normal?
my dell streak on the other hand rarely crosses 30C even on heavy gaming...

it's normal i'd say, mine does exactly the same. Infact most of my android handsets have done the same, must be due to the high processor power i guess.

When i have wi-fi off then the phone doesnt heat.
I think this happen cause of of many apps running in the background.

I never use the wi-fi on my handset apart from tethering, which is only occasionally but my handset heats up whilst playing games.
I think it's just down to the size of the handset. To fit everything into such a small body, all the components have to be very close together and that will impact how heat dissipates.
Think about laptops, they get noticeably warm when under heavy load in a way that desktop PCs tend not to, because there's more room in them for air to move and heat to dissipate - it's just the same but on a smaller scale, the differences in size of phones is obviously much smaller but so is the amount of heat being produced/power being used.

I would just like to say that the arc does not heat up very much, compared to an Atrix, that is. That phone regularly reaches up to 36c, and people have told me that going up to ~50 was NORMAL for it (eg using GPS navigation). The top portion also most likely holds the CPU and the rest of the components. I wouldn't worry about it too much..My arc is frequently around 30c during use. I think the battery life is quite good though

yup I thought so..its gotta do more with the size of the arc and what all it can do...and if you can go upto 50C then there is a long way to go.....
however, take for example my dell streak..its a 5 inch screen in a body which is 9.9mm thin...so a big phone and pretty thin but still it doesnt heat up too much...
on the other hand think about the Samsung galaxy s2...8.49 mm and a dual core processor...probably be a fireball after you play graphic intensive games on it for sometime..

Noticed it as well. My advice ?
Step 1. Buy a silicone gel casing.
Step 2. Place it around your phone.
Step 3. ???
Step 4. Profit.
Basically just ignore it - I'm pretty sure up to 40 celsius is alright, and the only reason why you notice it so much on Arc is because of how thin the device is. With summer coming though, I'd lay off gaming in direct sunlight

I once had quite a long session of angry birds; And after I quit, my temp was at 44゜C
Regardless of unhealthy temperature, it's still working up till now.

mine averages around 35. my 3G is always on and when on skype vc for a long time, it hits 43/44 too. but its due to the thinness of the handset.

It make not be incredibly thick but given the size of it's footprint, the components can probably be spaced out a bit more allowing the heat to dissipate more effectively.

My arc also heating up when I play dungen defender is really really hot especially the LCD screen...i feel that the tempreture is more than 60C ... will it damage the phone?

Jesus people, youre running a 1GHz CPU and a 3D graphics card flat out in a package not much bigger than a PCMCIA card, i think you can expect it to get a little warm.
When i think about the size of the heatsink+fan i had fitted to my first 1GHz desktop CPU to keep it from melting itself into a puddle of silicon, i'm amazed that modern phones manage to keep from spontaneously combusting.

^ what he said. remember, with higher processing power comes with higher heat discharge.
kinda offtopic but compared to the x10 where the cpu is under the battery, the heat would transfer to the battery causing it to overheat and reboot. i'm glad SE placed the cpu away from the battery.
it also seems like they've added a larger metallic plate (can be seen under the battery) in the Arc for improved heat dissipation.

+1. although bat temperature almost the same with my old phone, arc definitely feel err, cooler?

Hi guys,
My first time to post here, I know its normal for arc s to heat up when playing games. But is it also normal if on idle? it heats up to 38 degrees celcius. It concerns me because it drains my battery so much. Thanks!

all CPUs nowadays have a temperature threshold up to 70°C .. that means if the phone hits this temperature it will shutdown automatically, if this doesnt happen you dont have to worry and i think you will feel the difference between 40 and 70°C

Thanks for clarifying mate . What concerns me though is when its idle after charging @100% sittin' there say like 10-20 mins, check battery and boom! almost 50% was lost.

crazy overheating

I have had atrix about a week now and I have been having some extreme overheating issues. After about 15 minutes of watching a youtube video, according to temp monitor lite, my cpu temperature rose to about 55 degrees celsius. Is this nnormal? Or should I as for a replacement?
Thanks.

There us several threads about this....
And its normal idk why.
Mine its at 55 or more and battery get like 43+

Yes, it's hot, but apparently it's normal. Scares me when it gets that hot, but I haven't heard of anything really bad happening to anyone or their phones.

Are you people saying its normal .. as in a lot of people are experiencing this?
Or
saying its normal as per Motorola saying its normal?
If its the first option, I would hardly think that is safe. Ever think its a device wide ISSUE? Unless Motorola say that the device has no issue running at those temperatures, then I would really doubt it is normal.
Do you think this phone has some sort of unseen substance in it that prevents it from being damaged at this kind of temperaturewhich no other smartphone has? There is no extra protection for the sim or memory card. Which obivously are not meant to deal with excessive heat

If the phone had active cooling for the processor (like a fan, hahaha.) and it still "overheated" then that would be an issue, otherwise you're looking at a 1GHz phone with twice the cores of any previous phone at the same clock speed. What are you really expecting?

I dont agree that its normal for the phone to get hot regularly, i definitely wouldn't put up with "crazy overheating". And I dont use my Atrix moderately either, I'm constantly on it. TiBU tells me I have 417 system/user apps as an example of my extreme use. There are a couple other threads on this subject, op you should search them out. WatchDog will monitor your apps and let you know if any are misbehaving.

From Motorola:
"It is possible phones will become warmer during heavy use. This is normal behavior especially if you are transmitting data, talking for an extended period of time, or playing games or music on the device. In these conditions, the phone is transmitting and utilizing alot of power on the device which will generate heat.
Motorola phones manufactured in 2009 or later have a "cool down mode" function. This feature is designed to protect the battery and circuit board. If the internal temperature of the phone exceeds 136 degrees Fahrenheit, the device will shutdown all functions except emergency calls. When this happens it will display a cool down mode message. Once overheated, a phone will not regain full functionality until the internal temperature drops below 136 degrees Fahrenheit. Ensure you are not leaving the phone in locked cars, in direct sunlight, on warm or hot items such as heaters or radiators, or any location that produces heat that will heat up the phone."
If it gets hot while charging the battery, and doing nothing else, there is a problem.
Now, please don't give up your day job, because being a smartass isn't working for you! Don't let the doorknob hit ya where the good lord split ya on yer way out!

My phone has never been over 105 degrees Fahrenheit and that was only because I was trapped inside a black car for 30 minutes with the AC turned off and it being 95 degrees out :?/

Ok .. you showed a critical threshold of the phone. Do you think pushing the phone to excessive heats but staying below that threshold is good for the phone? Notice that it doesn't mention how SIM cards and memory cards will continue to respond when being exposed to excessive heat with no ventilation or circulation ..in fact your quote clearly says that feature is for the bAttery and circuit board
Bottom line..
you can push your phone to 130 degrees (since that's below your shutdown threshold ) and I will spread out my usage and keep my temperature down to a minimum ... and my phone WILL last longer than yours and I WILL have less issues with it.

Highest my battery has ever got is 48c
highest my processor has ever been is 63c
was the phone hot? probably.
processor normally sits at about 45-50 in my cardock as per what setcpu says
battery sits between 40 and 45 in the car dock.
Watching a movie in the car dock whilst my kid was in the car setcpu says it hits anywhere between 55 and 60.
It leads me to believe that the max operating temperature for the CPU is right at about 65c, and teh battery right about 55c.

So you are basically talking about the SIM card and memory card on all phones which are going to come out with dual core and no active cooling, cos they are all going to get hot. What Motorola has stated is what any manufacturer would and does. They have given us their safe operating threshold. Now, 136 degrees is a lot, but how much of this heat affects your SIM card and SDCard? I don't know, and you have provided absolutely nothing to substantiate your personal claims. Bigger doorknob needed I guess!
I simply responded to the OP telling them it's normal for this phone to get hot. If you want to continue down this avenue we can, but until you have something from a SIM card manufacturer and SDCard manufacturer substantiating you claims, I'm done.

Considering the memory card and SIM card are not far from the battery and are trapped under a cover... a lot of the heat would be affecting them as well. When did I say anything about dual core at all? I don't think I even typed those words out.
Point is that I don't know if most of these people are even doing enough tasks on their phones to even get TWO cores aggitated enough to put out that kind of heat. All of my other smart phones were pushed much more than this and have remained pretty cool to the touch. Even one with a metal battery cover.
I was more replying to the many posts across the ner and people I know that have the Atrix heat up too much and for too long.
As far as OP goes..
"I have had atrix about a week now and I have been having some extreme overheating issues. After about 15 minutes of watching a youtube video, according to temp monitor lite, my cpu temperature rose to about 55 degrees celsius. Is this nnormal? Or should I as for a replacement?

When you're streaming video the heat will increase, but make sure you dont let it stay hot for increased periods of time. You dont need to request a replacement unless you are experiencing excessive heat frequently.
Also, when streaming - try not to have GPS and other things like that running in the background.

[Q] LG G2 Operating Temperatures

Ok, I searched the forum about this topic and didn't really find anything answering my questions. I'm currently coming from a Droid RAZR and it ran hot to say the least. I can't get a straight answer on this phone's operating temperatures and I'm trying to determine whether to put a thick case on or not(with almost no bezel, I'm paranoid it will break on first drop). From what I've read, about 60% of people aren't reporting very much heat. The other 40% say there is a huge problem and most have had to replace their phones thinking it was a defect.
When it came to my RAZR, at rest with a case on, battery temperature would sit at just under 87 F. Under heavy use, I've hit over 124 F. Without a case, 83 F, the highest I've hit is just under 117 F. Extremely significant when you can't remove the battery and swap it out. I believe that it led to it's premature failure. I want to avoid that with this phone.
Is anybody keeping track of their phone and battery temperatures?
What apps and/or widgits do you use?
What is the normal at rest temperature?
What is the heavy use temperature?
Thanks everyone. My phone gets here in a few days and I want to be ready with a case.

I don't keep track of it. However this phone does get really hot (uncomfortable to hold) when playing games. With Tpu cases this was less noticeable. But lately I installed skinomi stickers for back protector, and it always bother me when it gets hot this way.
That being said, normal uses such as Internet, music, YouTube, xda, camera.... The phone only becomes slightly warm.
-LG G2

I keep wondering why no one makes cases that help dissipate heat, for how hot modern phones get! If anything, most cases insulate the phone and make them get even hotter!

Admittedly, I'm not a gamer but the only times I've felt the device get hot enough to register with the Incipio Feather case were: 1) after a wipe/flash, and all my apps were downloading again from the Play Store and 2) when wiping and the device was plugged into the wall charger (CPU temp was around 100 degrees) - other than these 2 instances, I've never felt heat thru my Feather case.

Honestly i just replaced my phone due to overheating issues. It would literally shut down or restart just running the camera for too long. After reading some other reports in the forums I decided to send it in and get a replacement. My new one came in yesterday and absolutely no overheating issues. Even can run antutu without a reboot (my other G2 would reboot about 14% in). So from my experience there was a batch that had some thermal issues... I got mine the first day it came out.

I am using this case full time: http://goo.gl/0u05G5
I use Battery and CPU-Z to check battery temps. Even with over an hour of straight gaming, I have yet to see it get above 98F. I constanty run the screen at 80% brightness as well, as that can be a contributing factor. The games I have played this long with are Riptide GP and Madden 25.
You really cant feel any heat through this case, and hand temps are too subjective anyway.

I'm currently in the design step of a case that uses tubing to disperse heat at the top corners of the phone to cool it down and keep heat away from the hand.

Are you guys talking about battery temps or cpu temps?
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.

My G2 gets also around 55°C when using the phone normally (youtube, browser, etc.) and over 67-68°C while gaming. I think this is normal for a high frequency 4 cores CPU. Right?

Hey, I received my LG G2 yesterday and i've been experiencing cpu temperatures of:
42-48C being idle
52-59C during browsing, facebook, viber etc
62-64C when on youtube (after the first 5 seconds)
65C when on gps
As for the stress test after 1:20 and up to 20:00 it was around 72-74 C
The phone feels hot all the time though with no apparent reason.
Screen brightness is set to 30% all the time, 3g connection is off and I only keep Wi-fi on. I even tried turning off features like gestures, I don't know if it is of any relevance.
Of course I haven't trying gaming yet, since I'm not really interested in it, but I want my smartphone to be functional without burning up.
Should I return it and ask for a replacement? Or is it an issue with LG G2 or Snapdragon 800 generally? Will it be a waste of time?

Galaxy s8 Gets Hot

Hi i bought the device two days ago and whenever i use it (i start opening Facebook, instagram, WhatsApp and other apps) it gets Pretty warm in the right side or the screen and behind. The CPU reaches 50 degrees and sometimes 55 and the worries me. What should i do? Is it normal or should i return it? I previously had an Honor 7 and it reaches the same temps but it doesnt feel that warm at the touch, it Just gets warm in the bottom left corner.
the temp while i'm typing is 41C, outside its 33degrees C and inside(where i am now) its 24degrees.

I do not believe this is normal whatsoever. My S8+ has been one of the coolest-running Samsung phones I have ever owned. You might want to return/exchange it if that is possible.
I have not used/tested with any apps to determine actual Temps but it never gets hot. It gets warmer but not very hot (like my S7 Edge did) when using Gear VR.
Have you done the simple things like closing all apps & rebooting? Clearing cache, etc? Maybe some app is "stuck."

Yes i tried everything

After how long of using these apps does it get warm, right away or after 5-10 minutes?

I would say 5mins. Now it gets maximum 48 degrees in the CPU but i feel the screen and the body Pretty warm... Maybe it's me... I don't know. Feel free ti suggest me what should i do

it is absolutely not normal
my first device share the same issue with your's
well i ask for a exchange, the new unit just go to 45 when running games, most of time it wouldn't even reach 40 degrees
but
new device came with new problems, red tints, home button problem
it's up to you
ask for replacement until you'er satisfy with it

I would get an exchange(Yeah right the real me would hold on to it until it melted because i'm lazy). So far this is the coolest smart device I have ever owned. Even when playing intense 3d games and emulators it only warms up a little.

Thanks Guys! I'm going to return it on Monday.

If you're constantly scrolling and opening posts the phone will get warm, Facebook isn't exactly a battery friendly app, but if you're stuck at a post and reading it for a while it shouldn't get warm, it really depends how you use the phone. I can get my phone warm using twitter too. My friends z5 with the sd810 gets toasty.

Well i dont know what to do... I'm going to return it anyway and see if it gets better. Thanks for your help.

Mate. The CPU throttles when it reaches 80C. What are you worrying about?
I advise reading your manual, which specifically tells you that the device will heat up with use and the heatpipe is located on the top right section of the phone x)
The reason why it may feel hotter than your previous (?) phone is because the metal rim (and whole body) acts as a heat spreader and the heatpipe connects to it with a thermal pad.

Okay but the warm feel is annoying.

Reduce your brightness and it'll reduce the heat

Let him get a new device. It's a better idea instead of dealing with that crap.

Trueee ?

Cpu temps keeps spiking up and down on any device that actually has a cpu.
What you need to look for is battery temp and not cpu temps. I consider battery temps a more steady measure of over heating rather than cpu as they dont spike.
Eitherways heavy bad background apps will make any device hot. Now if your just browsing on chrome with no background apps and your device temp ( battery temp ) is around 40c in a 20c room thats when ill be worried and exchange the device.
But hey thats just me
Gd luck !
