Safe battery temp - myTouch 4G Q&A, Help & Troubleshooting

I didn't see an answer for this anywhere. What is the maximum temp this phone can safely handle before it starts getting damaged? It's starting to get warmer and i want to know when i should start to be concerned.

Be concerned when it enters the 100's(F), which it gets to while charger sometimes at high freqs and around 110ish. With normal use mines stays in the 90's or 80's.

I think it got up to 114 once and I had pulled of the battery cover and held it in front of the ac til it hit 85 degrees.

What freqs do you use on your MT4G? According to your sig you have MIUI, no?
That rom should run fine on Scary/Conservative instead of demonspeed or smartass. Temps will be lower with Scary/conserv governor enabled.

Odd..Unless the phone is kept in a warm or hot area, and is being used heavily too. Under 1GHz the temps should be fine, do you use the phone a lot?

mine hit mid 160's one day when my charger didn't stop charging (was at 99% for a couple hours) didn't do any damage, still on original battery and seem to get decent battery life on fusion/faux 0.7 kernal.

OMG i would be in a panic if i saw battery temp that high! I get concerned over 110.

my phone overheated to the point where parts of the touchscreen wouldnt respond. after it cooled down...everything was fine.
i got this when using assisted gps....

You're putting the HW parts at risk..Especially the CPU which can fail from those temps, this isnt a desktop CPU which has cooling to help the chip. These mobile chips shouldnt stay at those ranges. How can you even hold the phone at those temps? That's just crazy IMHO.

I see, well do you use OC too or normal frequency range? I used to have a Sammy before the MT4G, and it would get really warm even w/o changes to CPU clock(But it uses Conserv. by default). These 1GHz+ chips generate lots of heat, I wonder if this is related to those bad EMMCs failing too...

Overclockin

So what is a safe temp for the battery to be running when you overclock the x. I think I red somewhere that the battery can handle up to 65 degrees c. Also does the x have the cpu temp monitoring probe? I thought I heard that the x doesn't?

Highest mines been was 104° Farenheit while overclocking to 1.45... Usually its around 89° F

Wow ok so temps that high are acceptable? I was a little worried when mine was running around the low 40's. Seems that the battery door gets pretty warm around that temp.

What are you using to overclock? Normal operation on my x without being overclocked, under load of course like streaming music and video, I see temps around 38 celsius.

Acceptable?? Sort of. Just because the phone CAN run at that high of a temperature does not mean it should be run for extended periods of time. Excessive heat is bad for any type of electronics. If you are OC'ing to the max, I would try lowering it a bit to see if it works good and the phone does not heat up so much.
They go into cool down mode at 140

How hot do you run?

Currently at 102.2F as reported by setcpu widget while plugged in and using it for the past half hour or so. Seems kinda high to me, what's everyone elses experience?
Sent from my DROID2 using XDA App
Well when its plugged in it will be warmer than normal. Right now my phone has been on with constant texting and random other usage all day long and I am at 80.6 degrees
My phone stays in the mid 90s and early 100s with regular use. It only gets in the 80s if I leave it completely alone for an hour or so.

I stay mostly in the 80s and can get into the 90s with heavy use. Don't think I've ever passed 100, but there's a chance something like psx4droid could have pushed me up. I average about 86F.

I do, its set to 800mhz when charging. 600mhz if it gets above 104F regardless of charging or not. Leaving it alone on the charger for the last half hour the temp shows 92F. Just firing up Xda app and typing this out the temp has jumped to 98F in about a min of use.

Are you guys using SetCPU for profiles and overclocking, or are you just using it for checking temps and current speed?
These are the droids you are looking for.

I was using it to check temps for this but I use 2 profiles, which may help my temps (def helps my batt). The default profile is 1000 max, 300 min, on demand. The other is when my screen is shut off, 300 max, 300 min. I've found this has saved me a pretty sizeable chunk of battery. I tend to listed to music 7-8 hours a day and while it doesnt need full CPU it will use it if it gets the chance. Restricting the proc to 300 off has never caused any issues and I can get from 8am - 4 or 5pm staying over 70% battery I have the unstable apps overclock and used it for a while, but kinda came to the conclusion that I can't really justify needing to overclock yet as I never see any lag. I guess if I run into any lag at some point I'll prob clock back up to 1.3 or so.

I did overclock, but it ran way too hot, like 107F during normal use and didnt get below 100 dormant. 1gig is high enough to me. I have it set to underclock when charging or when below 50% battery or when above 104F.

Only other idea I have is downloading Droid Overclock and try running at low or ultra low voltage. Make sure to make a backup first. And try low before ultra low. Individual devices can be picky about a lower voltage and can go into a bootloop if it can't run on a lower voltage. Droid Overclock has profiles like SetCPU.

2 hours of screen time there, that seems about normal to me. I'm lucky if I squeeze out 3 hours of screen time throughout the day.

It depends entirely on what you are doing. 2 hours of screen time (even in ideal conditions) will most likely get through half of your battery.
What screen brightness settings do you use?
What were you doing with the "screen on"? (i.e. gaming, video etc).
What kernel do you use? Try the Faux 1.0 Ghz kernel (if not already) and consider undervolting.
I imagine with the combo of Faux's stock kernel, undervolting and perhaps reducing screen brightness will see 5ish hours of screen time.
It was on around 85% brightness due to being under direct sunlight.
My kernel is faux's 1.45 for CM
Over 80% of the time the clock was around 200, 400MHZ as stated by SetCPU, and both those clocks are undervolted by 50.
I was browsing the whole time.

Wow no wonder. Roaming for 2 hours with brightness nearly on full will definitely drain your battery.v Plus the 1.45 Ghz kernel overclocks the RAM and GPU also. You might want to get an anti glare screen-protector and flash the 1.3 Ghz kernel and use wifi.

Umm... wifi wasn't an option back there, and I don't use screen protectors. BUT I didn't know that bit of fact from faux's kernel, I'll put in the 1.3
BTW, Green power pro does help a ****load on keeping battery alive.
ps: anyway to control RAM and GPU clocks the way we do with SetCPU with the... well... cpu?

I don't believe setcpu functions correctly for dual core devices, I remember reading, albeit a while ago, setcpu only effects 1 core, leaving the second untamed.
Please correct me if I'm wrong. Stock cm kernel has plenty of ass behind it, no ones playing bf3 on their handsets....yet...

Watchdog shows the suspend process and android media process taking up about 30% usage constantly. Signal is strong when I'm at work, constant 4-5 bars H+
Even after a full wipe and clean install of CM7 those same processes throw up alerts immediately, I will get al alert for the suspend process every few mins.
Background data off, no email syncing or anything. I'm lucky to get 3 hours screen on time or pandora streaming. I bought a new Motorola battery about a month ago and I don't use GPS or wifi.
Running stock, aura or homebase and the drain is gone... they aren't any good IMO tho.
For now I'm carrying a spare charger everywhere I go till the nexus prime is released.

Galaxy s3 hot problem and soloution (experimental)

Hi guys I am from India and on international s3 and face a problem that s3 get hot upto 48c
I have a solution for this(must be work)
1. First of all disabled bundled stock apps like chat on etc I have attached a screen shot of disabled apps on my s3
2. Off NFC android beam.
3.disable s voice( big battery eater)
4.must disable s memo and exchange mail
5.clear cache of all files and apps weekly
6.flip board users plz clear your cache routinely( this apps has a network bug that eat more battery in less time.
7. Set sync of apps like Google +,mail,wheather to 6 hours.
Screenshots are below.
Plz tell me after disabled these apps attached below that the tricks work or not

48°C is really like nothing. I remember SGS 1 & SGS 2 especially were getting almost 60°C.
So - unless some expert denies - I'm pretty sure temperatures up to 70 will not make harm.
With one exception: temperatures above 40° will shorten battery lifespan in the long run. Li-ion batteries don't like this.
Sent from my Galaxy SIII
That sounds crazy, 70°Celsius? How can you actually still hold the phone on that temp? Almost impossible. My S3 never reached 40° Celsius once so far. But i remeber my HC Desire, when it was very hot outside, it reched almost 50° Celsius and it was HOT like **** in the hand i couldnt hold it very long tbh. And i dont think that this is good for the phone.
70°c can damaged your s3 CPU and you cannot hold the phone. So plz don't make such a comments on temp.

I have read (will post the link if I can find it again) that if a battery gets to 140°F then it can go into a self heating mode, not allowing it too cool down, and eventually catch fire. However, I have accidentally left my dx charging in my car on a hot day and when I came back out, it had shut down and had a "battery too hot" notification. That phone would power off if it got too hot.

My gnex once hit 110c CPU temp and it still works fine, it was regularly hitting 80-90c during benchmarks.
To say that 70c will damage a CPU is absolute nonsense, a quad core CPU running at 1.4ghz will hit 65-70c no problem under full load before temperature throttle kicks in and limits the frequency to cool it off.
Battery temp is a different story, 70c battery temp will probably end up damaging your phone/battery.

Yes I do mean Celsius, and a CPU isn't made of water...
It shut off as that is the safety cut off point for that particular CPU.
I had temperature throttle turned off.
Quite a few people have hit that temperature, go to the gnex forums and ask Simms22 if you want further proof.
I KNOW a CPU can handle that heat because I have actually seen it.

Hi,
I agree with nodstuff and I can confirm
The same thing with my Gnex (not with the same kernel ) With a modified CPU temp limit my Gnex is going up to 98°C, never try with the CPU temp limit disabled but indeed it shut down at 110°C, it's a fact and it's in some doc of TI.
And about the temp of the SIII here we talk about the temp of the battery, not the CPU temp, this is not the same thing, although there is some correlation (but actually with, for example, a battery temp of 50°C, we don't know the real and actually CPU temp)..
When will you have an CPU temp in the SIII??? There is a CPU temp sensor but If I'm not wrong for an application to read the temp the kernel must support it (it's hardcoded).And as far as I know actually there is no way of knowing the CPU temp.
At first with the Gnex it was the same thing, no CPU temp and Franciscofranco has enabled it (the reading by an app) in his app (and also with anothe 3rd apps after) so we can see the CPU temp in real time.
I really missed this feature with the SIII...
May b it can handle so much of heat ..but the question is about using the device whn its hot..do u think its will b very convenient to use the device whn the device is at 100 degree?
I guess its not possible !

Hi,
Hot for sure but obviously not the same temperature of the CPU.
Temperature dissipated, yes, but not 100% transmitted at all the phone. CPU at 110°C you can imagine that the screen is not at this temperature for example, like the back cover, otherwise beware of burns and it's not the case.
When my Gnex reached 98°C it was hot but not unable to hold in hand.
Guys, you never used a Gnex (or another phone maybe) without a CPU temp limit, so disabled, or a modified CPU temp limit with an higher limit before thermal throttling...? The phone is still usuable.when I read you speak about very hot, extremely hot, or overheating with a battery temp of 45°C... Should not you know the CPU temp...
Ok the battery temp could be useful but not as much as the CPU temp...
