Phone gets really hot - One (M8) Q&A, Help & Troubleshooting

Is it normal that my phone gets 106 degrees F after 20 minutes playing a game. It feels really hot.

So this will not damage my phone?

Nope,
Max of these kinds of SoC's is usually around 90c (194f), once you count the thermal conductivity of aluminium into the equation that 41c(106f) is likely around 60c(140f), well within max limits, even if I've calculated thermal conductivity and density wrong, the max it would be is 75c(167f).
Sorry about using celcius and converting back to f but I am from a country that uses that unit.

While within the CPU tolerance, could this affect the battery's longevity? I also play hot games, as well as using wireless charging which makes the phone as hot as gaming does sometimes. Could this affect the lifespan of the battery by "cooking" it? As we'll never be able to change the battery in this phone, I wonder if excessive heat will impact it in any way?

Phone getting hot

I have noticed that my phone grts VERY hot when watching a youtube video on 4G. Also playing games, and just generally using 4G makes it very hot. Is anyone else experiencing this?

Never noticed much of a temperature increase on my phone.
I can understand it heating up like a laptop when under heavy load. do you have an app that tells you the battery temperature ?

This happens to me but playing games not so much video streaming... I have battery indicator, drop the notification bar down and battery temp is about 40oc (Aussie metric) so not sure what that is in Fahrenheit.

Yeah my phone also gets hot occasion, only "very hot" when I'm charging it and it's on my bed or under my blanket. I figure that's due to it not being able to air out properly

i think it is normal for the phone to heat up when multi tasking . my phone gets hot too , it even scares me a little lol.
Batteries heat up...it's normal.

Lets put it this way..
I stopped my car once because I thought my leg was on fire, I jumped out of the car as if I was burning..
Through heavy jeans..
It was my phone (older one)
We are holding high powered devices wrapped in plastic and metal (mostly plastic)
More powerful than many older laptops, WITHOUT any cooling devices..
its normal and will shut down if it get too hot

Flashing notification light

Hi, when I play games or watch movies on my one x it sometimes start to flash red - green on the notification light.
I think it only happens when I have the charger plugged in. Anyone know what it is? And if its any help, I'm running leedroids Rom.

Using more power than the charger is outputting

Have the chargers changed over the year's? Currently using the one that came with my desire.

I was thinking this but I'm not too sure, I was wondering if the one x charger would have higher power output due to the beastlyness of the phone. I however never use it because it's short...use an old blackberry charger seems to take about the same amount of time to charge tho

Generally, those two circumstances tend to occur simultaneously!

Yup! Do NOT play games while charging...it is a sure way of pushing the thermal limits!

No, its pretty much an industry standard that micro usb chargers run 1A @ 5v
If the charger is really old it could be 800mA but not likely, easy to check though, just check between the pins on the plug

oh so its not overheating?
It's definitely overheating. I was watching an hd movie using sw code and charging (I had about 20% battery, so it was taking the whole amp), and the light began flashing. I quit the mx player and saw battery widget reporting 49 degrees Celsius and battery status was 'overheating' I have to mention though that I had my phone placed onto a pillow, so no chance of dissipating the heat whatsoever. I presume the same happens when you play a game and hold your phone. My advice is just to wait a while for the battery to go up enough, so the charger begins the slow cycle - then you'll be charging with a few hundred mA and it will be easier for the phone to handle the extra heat.

Well when the led flashed like that for me I was playing shadowgun and the battery dropped a percent over the time I was playing with it charging the whole time, but like someone said above both will happen. The phone was hot for sure
Sent from my HTC One X using xda premium
Well I used to have overheat problems as well but I fixed it by doing a hard reset. My phone doesn't overheat as it did before the reset and I can easily play games on the phone while charging. Even after a hard reset, my phone easily hits 43 degrees though. Just thought to share this with you guys.

I used my touchpad’s charger which is a 2A charger and it charges twice the speed. So you can try using any tablet's charger for a fast charge..

[TIP]Prevent heating OneX

Just to let others know I use several frozen gel packs which when I am using my OneX for hardcore gaming I place the gel backs under the phone to keep it cool. Anyone else do this?
Heat + cold = condensation...not a good idea.

Dave is right...This practice of yours will damage your phone on the long run. If your phone regularly reaches temperatures above 50 degrees celcius, you should consider returning cause faultu hardware might be the culprit behibd your overheating issues.
Gel packs? Eh? My phone gets warm when playing games but I deal with it. My ipad3 gets crazy hot but nothing bad comes of it. I have faith in htc.. If it gets hot then find but I shouldn't have to worry about it getting hot and it possibly overheating

Actually for Laptops Thermapak has a Heatsuit which aborts the heat and keep it cool. I wish we have one for our One X,. It actually works pretty well.
On my HOX the battery health says "Overheated" after gaming for like 20 mins
I think the most useful cooling tool is the fan...
but maybe the air conditioner is great...

true there can be condensation but I've been using gel packs for about 2 years, always on my sensation when gaming at home, desire hd as well as now the one x, never had issues. cooling fan is one idea but the gel packs are awesome. you can buy portable cooling units that are designed for phones albeit more expensive

How hot can cpu be without being unstable?

I am using setcpu to put variety of profiles and one of them is cooling profile. Which basically is underclocking so cpu cools down a little bit, so my cpu doesn't have any trouble. Right now I have my cpu temperature set to 73c, but I wanna know how hot can gnex cpu can get without causing any trouble thanks!

110 the phone will shut down. I would set the limit at 80 personally. Though I've never seen over 62, rarely higher than mid 50s.

80s? That sounds a lot to me but who am I to judge? lol
Thanks so much
I agree 80 does sound a little hot, but keep in mind there's no cooling fan or anything and the components are enclosed in a plastic case + any case you may have.
I usually only see 60 when I'm doing something like running GPS in my car with no ac and the outside temp is already 105 Fahrenheit.

I play games from time to time and that gets pretty hot. Max at around 70 maybe? But this thing gets super hot when using while charging....

For most Processors 80c is really pushing the limit on tolerance. You generally don't wanna go higher than upper 50s low 60s.

so you're saying I should set out around 60, correct?

Temperature?

What sort of temperature are you guys seeing while playing games? Am getting 40c kinder hot to touch after while. Shame because battery life is just so good.

It should be fine, it doesn't get any not hot than any other device. You just feel it more because it's metal.
It's actually better for the device, because the heat is getting expelled. Unlike plastic phones where it stays inside of the device.

40c under load is great. You just feel it because aluminum is a good heatsink material.

Yeah mines about the same as yours between 35 and 45
It's ONLY hitting 40 & you are only feeling it because of the design intent. Think of the alloy body as a heat exchanger, just like the plate type used to indirectly transfer heat from boilers or steam generators to water for domestic or hydronic use. Just like in those applications, metal alloys are much better conductors than plastic composites (which is why insulation/insulators are made of ceramics or composite materials), so the transfer of the heat energy away from the device internals to the cooler ambient atmosphere is much more noticeable on the M8. Other devices are also generating as much heat, but they are relying on ported vents & copper heat tape to remove a much more limited amount of heat away from the device internals. You also notice it to a much lesser extent on those composite plastic devices because they are using insulative materials, so more of that heat energy byproduct remains inside the body for a longer period of time. The only time the plastic devices really have an advantage is in hot climates, when the device is being used in a windshield mount & even then, once the device heats up, it still takes longer to dissipate the accumulated heat load.
40 degrees Celsius is a testament to the laws of thermal dynamics & why you see the M8 dissipating more heat energy.
