[Q] Heat - Galaxy S III Q&A, Help & Troubleshooting

Hello!
How can I check my phone's temperature, and what's the highest that is safe? My phone after about 20 min of Internet browsing is really worm at the bottom part of the screen and back. I want to be sure it's not faulty.
Another unrelated question: is the radio on our phone weaker than others? I'm comparing it to galaxy w and HTC Desire. And I'm constantly 1 bar down compared to them, also I've noticed that sometimes it loses connection to data and quickly jumps between 3gb h and h+.

[q] htc hd2 heater

Hi Guys,
I'm just curious, is anyone facing the strange warmness the HD2 radiates under normal use? Normal being, GPS off, Bluetooth off, only HSPDA is on. Perhaps there is an option to turn off the "Winter Heater Mode" ?
Thanks!
Benedict
Yes i am also having the same problem it generates heat some times...
Its the processor
My old Nokia N97 did it even worse than the HD2 and i had an Iphone 3G that could cook an egg if i stressed it while charging the battery at the same time.
It does get warm, but only when I am watching a video, browsing high bandwidth sites, etc. If it's just idle and it's hot, well, I don't know man.
My Nokia E71 heats up a bit for calls or Wi-Fi above 10 minutes, I guess its normal if the motherboard is pushed into more strenuous activity. More so with this monster.

[Q] GS2 Constant Switching 3G/4G

So there are a few related threads but specifically what I am looking for in this one is how to hard set the phone to "stay" on 3G.
While at some venues in town the phone constantly, every minute or two, switches between 3G and 4G which is drains the battery while I am there. Within a few hours the battery will be dead from full charge.
So looking for ways to prevent 4G from activating especially when I am at these locations. There used to be a setting in the G1 that forced it to stay in 2G. So anything similar or disabling certain frequencies that might help.

[Q] Razr XT910 overheating issue

Hello all,
Recently i bought Razr XT910 (1 month ago). Because of failure on power button on first handset, provider exchanged it with new handset, now everything is ok except..
On both handsets comes up overheating issue when i was using HSDPA/3G network data for internet surfing. In 20-30 minutes back side and front side (LCD) comes very hot. Application for battery temp shows in idle cca 27C after 30 minutes just web browsing comes up to and over 40C.
This never happen if i play games, watch videos. Also heating is not present if i access and browse over internet on WIFI connection. And i didnt root phone yet and i already done factory defaults.
Has anyone experienced the same problem? Any suggestions?
Specific of my phone:
651.73.30.XT910.NonEFIGSRetail.en.EU
Android Version: 2.3.5
SPU: 11 M1-2
Radio Version: U_03.1C.85P
Bootloader Version: 0A.67
Webtop version: WT-2.0.0-113
Thanks
Try to use the phone at different places. Check the signal reception. Low reception means higher transmitting power needed. So, more power needed and makes the battery and transmitter circuit work harder.

Thanks for reply. I tried this at work where i have full signal HSDPA (antena is 100 meters away and signal is very good), and at home i have very good signal on 3G network. I am not sure that the signal strenght is reason for heating... What about Radio Version: U_03.1C.91P, what improvements does it have?
I am on Asia GSM , HSDPA with 85P baseband. Everyday I download several podcasts from twit.tv and it is getting warm, but it cools back to normal after the download is finished.
Check any background process which may uses Internet connectivity all the time.
You can check signal strength at Settings. - About - Status

Normally you see high temps with heavy 4G LTE/CDMA phones. Haven't heard of many GSM phones on any brand ever overheating. May want to return it again. Sounds faulty to me, and the hotter you run, the worse your battery life will be.
@got556
I read about phones 4G LTE/CDMA with high temps, but as far as i know my phone is 3G (gsmarena). Mybe it is faulty, but this is second one with same issue.
@bahathir
can you mesure and post here battery temp while dowloanding or surfing internet for 30 minutes? Mine also cool down when surfing is finished, but meanwhile...it worries me.
I will check background services for activity.
Started at CPU temp : 31.5 degree Celsius. I am using OS Monitor app.
Opened YouTube and watched one of the clips in TheAlexJonesChannel. At the end of 7 minutes clip, CPU temperature was 35 degrees Celsius.
Next 15 minutes clip, temperature was 37 degree Celsius.
Another 15 minutes clip, the temperature was 38 degree Celsius.
Signal strength : -89 dBm. WCDMA only mode
Room temperature : 26 degree Celsius.
Now, it cools as nothing was happened.

I wouldn't call it was overheating since your case is normal. If you surf 30minutes nonstop over wcdma, any phone will get noticebly hotter but it wouldn't like you can't touch it.

What he said. An active mobile data connection will produce a lot of heat, especially when using 3G. When on 4G, your phone is using up a much smaller portion of the total available bandwidth so the radio doesn't have to work as hard, whereas over 3G your device and radio have to work much harder to maintain the necessary data rate.
This can be compounded by factors like ambient temperature, GPU accelerated applications (browser), the physical layout of the device's hardware, and even how you hold your phone while using it.
The good news is, 40°C is not a 'dangerous' temperature level for your battery. Given how high your ambient/idle temperatures are, you're really not generating that much more heat.
In general, I don't think you have to start worrying about Li-Ion batteries until they hit about 45-50°C (don't quote me on that), at which point you start running into issues like thermal runaway and damage to the battery.
Hope that helps.

Sorry, double post, but this is important:
Every Android device I've worked with will generate MUCH more heat when connected to AC power (there is a scientific term for this phenomenon, but the name escapes me). With rooted devices, I tend to account for this by creating an underclocked profile in SetCPU for when the device is plugged in.

Hi all.. My Razr XT910 touches 45° when I play games like angry birds or similar ones..is it considered normal?
Sent from my XT910 using XDA
Hi guys,
I am sorry for (very) late reply Recently i hit 44°C with active web browsing (facebook,news pages...) and i didnt watch any movies in about 20 minutes. The phone was really hot and it was very uncomfortable to hold it and touch it. In the meantime i contacted motorola support. After their advise i set phone to factory defaults and then i also exchange micro sim card (for free) just in caseif there is any problem with it. But problem is still present. So i decided to take phone to repair centre. They tested the phone for a few days and they said the phone is working normally. They also reflashed my current SW....On friday i got phone back and problem is still here...Now I wonder how they tested the phone and what is for them to normal operation. And i am also stuck at SW version. Does anyone know what are differences betwen GB,FR,DE, NonEFIGS and other versions? Is there just language difference or is also hardware diferences?
I am also worried what will happen in summer with high temperatures outside..
Well, I don't think is something unusual... Its same like your laptop - if the system is busy and the processor has lot of work, it gets simply hot..
Keep in mind that the razr has two cores and if you are playing games or watching movies or even browsing web containing some flash etc. it may get hot because the cores are running at 1,2ghz and it generates heat...
I don't think its something surprising and you will face it with every nowadays smartphone..
If the temperature don't get down after few minutes the phone is idle, check if there is some stuck process because it seems that most likely there is something running on background...
I personally use the System Tuner which gives me a great overview about the current phone's load etc...
@maarawoe
i undarstand what you are trying to say. But web browsing over WIFI does not generate that much heat, the phone gets a little warm not hot as on mobile data (aprox. 35-36°C) and also when playing angry birds or something dos not get that hot.
As i said i am just concerned what will happen on summer time.I hope that the phone will not explode
I will try that app to see more details what is happening with system.
How high temperatures do you get with razr?

I don't know exactly but definitely high enough that I notice it but not high enough to get scared :-D
But it really depends what exactly I am doing...

WiFi hotspots are usually 100m away at most; but since the range from cell towers can be measured in kilometres/miles, the power needed to talk to them is much higher. Some of this power is lost as heat. All devices with HSPA and LTE radios get somewhat hotter when the data connection is used heavily.
Recently trouble shot this same problem for someone else. Try this:
1) Turn off Wi-Fi
2) Go into wireless settings and DELETE the saved profile for the Wi-Fi network you're using (make sure you know the network key first)
3) Turn on Wi-Fi, reconnect to the network.
High temperatures are common under certain conditions, such as being connected to AC power, using multiple radios simultaneously (ex: GPS + 4G), CPU/GPU intensive applications, and of course high ambient temperature.
45°C is not dangerously high, but can indicate other problems. Anything higher than 50°C and you may start experience issues like thermal runaway (battery rapidly discharges).

Hi, thanks for replies.
@JPtheSmith - high temperatures are present only browsing net over 3G (we dont have 4G..yet). Even if Wifi is turned off. If i use Wifi for web i dont get so high temperatures. And the ambient where i use my phone is around 20-25°C. Maybe there is some incompatibility between phone gsm module and provider network. I will try to get another provider sim and check it.
I had a long talk with Verizon tech support about high temperatures.
The main causes.
1. Bad signal area, makes the phone work harder.
2. Running to many apps. To many Background apps can and will over-tax your phone.
3. Last but not least, HD games will max out your phones resources.

Heat and data connectivity.

With current smart phones always running hotter than the older ones. It has come to my attention that when my Padfone X gets to about 140(ish) degrees F it starts to slow down the CPU in order to cool off. I have no problem with this, other than the fact that the phone starts to mess up my data connection. I can be on 4G LTE with four bars and it will fail to open a website or communicate my gaming on Ingress. Also, when I brought it back to my work, it was jittery and only had about a 50% success rate with pinging www.google.com.
I know electronics do not like heat, but this is kinda ridiculous. I rely on my data connection when I am out and about playing Ingress. Since I don't drive and operate my phone it stays in a phone cradle in my window. Thus it does get to temperatures above 140 easily. The Samsung Galaxy S4 never had heat issues at that temp, it would need to reach 160 before it tried to shut down. At 150 it starts its cool down operations (slower CPU, dimmer screen).
I guess what I am asking is this:
1. is there a way to adjust the threshold of the device to 145?
2. will that damage the unit?
I have noticed my LTE modem fry at temperatures exceeding 155. So I can see that this phone is a bit of a Nancy when it comes to heat. Other than strapping an ice pack to the back, I am at a loss of what to do here in Texas.

Weak Network Signal Strength in LG G8x Thinq

Hi,
I am getting very weak signal on this phone, only 2 or 3 bars. If the same SIMs are inserted in other phone, it is showing full signal strength.Is this a generic issue with this phone? Any settings to improve it?

Bro i too getting the same issue ,i got 1 point in lg g8x and 3 point in my old one plus 5
But i feel the network is more stable low ping even the download speed is 5 to 7mb(play store download)
In lg g8x
No issues
Its same case with me, Then i tried digging into the phone settings -> System -> About phone -> Sim card 1 or 2 -> network -> Signal Strength, I got real time reading of the strength and then i compared with a samsung, xiaomi phones, It was almost same, Where LG had just 2-5 percent less signal , May be due to Glass and metal body, But even when i get a single bar , I get decent speed in the internet, But real problem is during calls, the voice of the other end gets disturbed sometimes.

Whether LG is having a user forum for their smartphone users?. Apart from the network signal, I am also facing high Idle battery drain. During night it is draining more than 10% with AOD off.
