How Hot Is Your Defy?

Like the topic says..
My Defy usually very hot whenever I surf the internet using 3G. Sometimes temperature hit around 45°C.. When idle on 2G, it stay around 35°C which is normal.
Anybody experience temperature above 45°C ? I'm running setvsel to minimise the voltage use and at 1000mhz seemed doesn't cool it down.
Sent from my awesome Moto Defy: Stock Rooted Gingerbread 2.3.3 - XDA Premium

mine 800 mhz reaching till 41 c without running setvsel.
i think its normal.
and don't forget the warms of the hands are part of it.
when i'm playing modern combat 2 less than 15 min get's hot.

The hottest mine has gone was 50degrees..usingit as a wifi hotspot
But the temp drops to 40 - 45 if there is full 3G signal...

I have reached temperature above 40 C occasionally. Heck I've reached 45 when using my defy as a router for the wife's iPod (immediately stop and throw the defy in a bucket of water for a minute afterwards..temp drop down to 26!!) .
If i am using HSDPA, temp will get high, 39 -41 Celcius is expected after an hour of heavy browsing. very rarely went above it unless downloading a big file.
But it is much better compared to before, right now i am using the central europe baseband running 2.3.4-134. When I am using stock UK or even SEA baseband, temp reached 43 after just 15 minutes of browsing.
I am in Indonesia, and found the Central Europe BB is the best for me.
I only get high temp from HSDPA, never from wifi or gaming. Played 3d games till my battery almost out and it only reached 40. Played a movie for 2 hours and the temp is only at 39/40. Transfer 4GB of data using moto portal Wi-Fi to my PC for 2 hour, temp is 37 and this is done today.
Here is my take, a temperature of 41 in using the defy is expected when you are using your HSDPA, anything above 41 is considered HOT for me.
This device tend to be hotter then say my friend Galaxy S. probably since it is water resistant so the heat/air outlet is limited.
dont worry too much, you can do what i do and dunk the defy in a glass/bucket of cold water should you deemed the device is too hot.

I'm on leaked 2.3.4, and I have highest temp when surfing on 3G 44 c, when idle the temp is about 28 c.

I would hope and wish this Defy will stand up at 50 c since it name of dust and water resistant mean no air or any ventilation in or out from this device. But sometimes it worried me of holding it when it becoming hotter. Normally I will open the battery cover after I finished my games or surfing and lay it down for a few minutes.
Note: I hardly get anywhere near 40 c when I was using Froyo 2.2.2 french retail version. Perhaps this gingerbread run 1000Mhz by default caused its temperature rise quicker.

I live in Texas USA. Here in the summer the temp' is above 100°(38°c) Fahrenheit 90% of the time. One day my wife left her cliq XT in the car. When we returned the screen was showing 'cool down mode'. When the home screen came up and I look at the temp', it was showing 58°C. I was shocked! Her phone still works properly.
So I think these phones can survive extreme temperatures.

Typically mine runs about 30C (86F). On a really hot/humid day here in Iowa, and while charging, it will reach around 45C (113F). I've got my defy running with setvsel at [email protected]/[email protected]/[email protected]

This look promissing! The phone actually will auto switch to 'cool down mode'.
Probably the mode will triggered above 60c. Thanks for the input..

Mine is above 35°C whith 1,3ghz/78vsel.

mine is sat idle at 26c but using 3g on a hot day i have seen it hit 45c it is running at:
300Mhz 22
600MHz 32
1GHz 52

40 degrees Celsius?

My Galaxy Nexus often increases its heat to around 42 degrees Celsius (108 fahrenheit) constantly with minimal use (light 2D gaming for about 5 minutes), surfing the app store and playing around with the menus for a 10 minutes. I have installed the battery monitor widget application (free) which tells me everything and gives a timeline of different temperatures the phone reaches.
Constantly the phone is 30 degrees Celsius (86 Fahrenheit) and above, even during minimal use of apps (only running one app at a time, I selected the phone to only use 2G networks and it has no data plan).
This seems very very hot for a phone. My Galaxy S2 doesn't get past 28 degrees celsius (82 fahrenheit) under very heavy use whilst on 3G. My HTC Mozart is the same as the Galaxy, it barely gets above this temperature. Is the Nexus supposed to get this hot?
So far my battery life is set at 17 hours battery life with minimal phone/texting on 2G (literally 2 text messages and 1 phone call per day), 30 minutes of light 2D gaming and zero music or videos being played. There are no programs running in the background and the brightness is set at 40% or below.
EDIT: Even on standby without use for hours the phone has NEVER gotten below 26 degrees celsius (78 fahrenheit) .

I'm hoping someone could share info on the heat of their devices/the normal range of heat that these kinds of devices should be putting out. It sounds interesting that this much heat can actually be created, more elaboration would be better though.

bumping for answers for op.

I noticed a dramatic difference in the temperature from my evo 4g. Some potential causes:
* high stock voyages (there is a great thread in the Dev section about uv kernels)
* when running modaco's brightness patch it got worse for me.
* since it happens with the screen off, it is probably not tht...

What's your ambient temperature?
Absolute temperature doesn't tell us much, what's useful is the delta between device temp and ambient temp.

The room temperature is air conditioned around 18 to 25 degrees celsius (64F to 77F). The phone should not be hitting above this range, especially on standby. It should not reach 40 degrees Celsius whilst texting/app surfing on 2G.

Same issue here.
My Nexus One's battery is at 24C (plugged in, not charging).
And by GNex's battery is at 37C (plugged in, charging)
Okay 37 is fine but 42 is not :/

right now I have flashed a few roms and am browsing tapatalk.. at 34 Celsius. Just applied my undervolts though so we will see

Mine increase more than 42c when using too.

Just bought the phone and mine seems to overheat too much... going to buy a case....

Battery says 46 degrees cel...

also i noticed on galaxy nexus it get too hot around the camera on the back and the earpiece on the front.
noticed the problem mainly when in an area with weak reception. or while charging the phone even with good reception.
its something with the radioROM or hardware.
any suggestions??!!

normal
Its normal! 76F when not in use 90-101 in use 101-120 with charger and using . I called Samsung . My euro gs2, at&t gs2 and my skyrocket all have the same temps remember this is a very thin plastic phone with battery right there behind tiny plastic cover . Think of it like this dose ur computer get hot when u use it?? ? Have u ever even thought bout that? No cause ur not holding it in ur hand .

+1
This is a dual core phone, it is going to run hot because it's a dual core processor with no cooling other than dissipation. It's not a problem unless your phone is actually crashing because of it. I've seen mine get up to 46C during long periods of gaming/charging.
I expect the hardware has been developed to tolerate these temperatures or we'd see a lot more "my phone overheated and now it's a brick" posts or even "my phone exploded into flames" posts. Have only seen a couple of the former and none of the latter.

Running hot after root, rom and maybe 'incorrect charger'
So like others here my GSM version Galaxy Nexus phone is quite hot at the top right corner back and front, near the camera. Only when the screen is on. Battery drops very rapidly too.. like 1% every 30-45 seconds...
This heat is brand new. I recently rooted and romed the device after the recent ICS update cause signal loss when the screen was off. I tried AOKP, various kernals and have now returned to the original backup of android 4.0.2. The heat continues with the screen being on, through all of this. Doing nothing, wifi connected... just on. Screen off no issues. No apps are installed except stock. Default Kernal again.
I also noticed i plugged the phone in with my blackberry playbook charger at the same time as all of this. The specs on that are playbook charger output is 5V @ 1.8A..
I notice a few other people posting about this so want to know if this might be rom related somehow, or if perhaps ive done something to the hardware from the charger. I've tried a spare battery that was not used with the charger at all and the heat continues.
There was no heat at all like this before this last 24 hours so its not 'normal use'. Promise Hope someone has some possible suggestions to try

Mine is at 31 right now.. listening music and xda... if play games it goes to ~35 if I plug it in it gets hotter than 40...

Temperature

The temperature of my 1x gets extremely high sometimes, especially when I play games, what is the highest possible safe temperature and at which temperatures is it risky to keep playing? Also, will this be fixed?

Yes.

It might be only placebo effect, but browsing with Dolphin Browser HD heated less One X than stock browser. It might have been only a coincidence and I haven't tested enough to reach conclusions. Yet, other users might confirm or infirm this impression.

This can’t be the normally operating temperature range. When my battery temp gets to 55 Deg C it reports the battery state as “overheat”. This can’t be good...

Ever since I used a custom rom my phone doesn't get any where near as hot, must be something with stock.
Sent from my HTC One X using xda premium

I played Riptide GP for a while and topped at ~38 Degrees. Even a 40 Minute Google Maps Navigation with attached Car Charger topped @ around 36-37 Degrees. Perfectly fine for me, tho other Games (or Demos) like Glowball which REALLY stress the GPU and CPU due to its graphics demo category heat up the phone to like 43 Degrees.
Other than that, I dont have any problems. I only start up Glowball for a couple of seconds to show off graphics power, not to do anything scientific in there.
EDIT: And what should I say. My standby time is around 26 Degrees when not in my pocket. In my pocket it goes up to 31-32 degrees, but thats normal since the casing kind of absorbs the heat of your body at some point.
When I surf the web for like 30 Minutes, my device never gets hotter than 34-35 degrees, even in comfy warm surroundings (like my flat).
The heat discribed in that article seems a little intense... Maybe there is a faulty batch with heat issues? The One X sure gets warm, but so did my old Galaxy S2 and on top of all, the old Motorola Milestone which became a rough ear heater when doing calls for more than 40 Minutes.
I had a 60 Minute call with my bro 2 days ago, and my One X just got up to 29 degrees... Dunno whats going on there. I always have temperature sensor apps running the first few weeks after I bought a new device.

>>>>“If the phone is in normal use without playing games or calling for long time, the temperature should be around 37°C or 38°C. But if you use your phone to play games or surfing internet for a long time, it will be normal that the temperature rises to around 55°C.“, official statement from HTC. <<<<
This is the one major gripe I have about the One X. It should not heat up to 50C no matter what. It may be "normal" for the One X, but it's not normal or good in general. I hope the next firmware update addresses this. I've gone through god knows how many phones and the heating issue is by far the worst with this phone. Some surfing and apps running for about 10 minutes should not warrant a jump to 40+ degrees in my opinion...

How Hot is Too Hot???

Pretty much what the title says. I just downloaded Modern Combat 4 & I have been playing it a little bit. I'm on CM10 w/ Ktoonsez's kernel w/ it underclocked a pretty good bit. While I was playing the game my phone got really hot! I had my max at 1.5 gigahertz & my voltage at that frequency is 1065 mv. I was reaching temps of 106° & 107°. I quit playing for a while & let it cool down b/c I didn't wanna mess anything up. How hot can I run my phone before damaging something? Sorry post was so long.

If you are talking 106F or 107F, that seems to be around normal temperature. That's what I've been reading in the forums while researching my own heat issues. My phone gets that hot, around 45c just using chrome and instagram to look at pics. And the back gets really warm, I'm guessing it's because of the thin plastic battery cover Samsung uses. I was thinking about returning mine, I just got it last week, but I guess this is a normal thing. Plus I'm stock with JB update through Kies.

106 107 temperature is normal. I have seen my phone get to 120 before when it was running a bunch of things at once. My phone is normally around 85 - 90 degrees when idle. I wouldn't worry about it until it get to 115 120 I would think.

Ok. Thanks to you two. Like I said, I am undervolted also. I have never seen these temps since I undervolted. I guess I won't worry about it too much. By the way, check out the new Modern Combat 4. It's pretty good!

[Q] Gets Hot, only when playing game. is it normal?

I started to play kritika and real racing 3. My new G3 gets to 104 degree F when i play kritika for 10 min, but the temp is only between 90- 95 , when not playing any game. i had the phone for 3 days. never had the dim down or auto switch off issues, only this heat. is it normal?? mine is LG G3 D851.

It's normal :good:

coincidentally, the battery inside the G3 says to not let it get hotter than 104F

The game can utilize CPU to the maximum so the unit can get very hot.

Nice, considering the ambient temperature here can reach 120 degrees on a daily basis...
Sent from my LG G3

Today it reached 106 in 7min when playing kritika(heavy graphical game), heats up slowly when playing clash of clan.
Do you think I should replace my device with my carrier?

YES
O yes...playing games with heavy graphics or watch movies for a long period can heat it up pretty quick ...I personally take the case off when playing to help it stay a little cooler, and if i am home i take the back of as well, since i have heard cases of damage from over heating. :good:

I was typing the Battery temp as 104 and 106. cpu is at 120 - 150F

It's the same with every phone I used for the last 2 years. Plastic, glass or metal, the phone still gets hot.
Sent from G3

if I buy a case and use it. would it cause more heat to be contained? or would it release more heat out? planning to buy a rubber case
