Temperature? - One (M8) Q&A, Help & Troubleshooting

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.

I haven't even noticed an increase in temperature, honestly.

Do you play much games?

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.

GN getting really hot?

Anyone else noticing their phone getting really hot? Especially at the top, right where the antenna is?
"Really hot" is a relative term. Please measure the cpu temperature with a program in the marketplace and update this post with valuable data.

Ooh okay, is there a particular app I should use?
But to describe, its hot to the touch. Uncomfortable on bare non-hand skin.
Yeah I've noticed the top right of the phone gets really hot compared to previous devices I've owned even the sgs2. I assume that as devices are getting thinner more heat will dissipate into the outer casing so its probably fine just a little disconcerting

I dont mean to hijack your thread but check out my thread on the issue here:
http://forum.xda-developers.com/showthread.php?p=20100575
The Nexus goes above 42 degrees celsius with minimal use while my Galaxy S2 stays at 27 degrees celsius with very heavy use (internet, 3D gaming, music playing, multiple apps running).

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 ?
Sent from my SGH-T989 using XDA App
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

[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

Permanent screen smudge

Hi, I was planning to sell my n2 to get the 3,it's in perfect condition with every accessory still in its packaging, however i think i won't get much on it since i have huge smudge on the top left of the screen. I dunno what caused it but I'm thinking it's due to playing tennis game on it a bit. Has anyone else experienced this?
Any solution?

Those are finger marks, you're right that it's caused by games. Notice there's 3 areas affected, where the directional pad is and where I'd assume there's buttons A and B in that game. And that's why I use a screen protector. If you don't then you can get the glass replaced, not recommended as it's not 100% safe.
It's probably the oleo phobic coating rubbed out in those areas. They do sell oleophobic replacement kits online. Try it out.

Then what's the point of having a smartphone if I can't play games on it without using a screen protector? This is disappointing

come now, it's a phone and not a suite of armour. anything subjected to daily rubbing in 1 certain spot will show wear and tear. Your logic is disappointing

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?
