J williams youtube user having heating problems

RE: this issue with this gentleman:

Not meaning to blow my own trumpet, however I used to be a fairly famous Overclocker, a few years back having being lucky enough to win two Overclocking titles,  designed motherboards for Universal Abit, DFI lanaprty, worked with Lamptron fan controlers and help to design new application methods for when I used to work for innovation Cooling and its IC DIAMOND thermal paste products.

So its safe to say in my humble opinion, that I have a good general idea on how heat is dissapated. 

Normally when a phone gets hot, the heat is spread throughout the chassis so in effect any metal parts of the latter act as a giant heatsink., however glass as you know is a VERY POOR conductor of heat (its an insulator) and thus will drastically spoil the the thermal efficiency of any mobile phone.

The Xperia 1 is different as one can only feel the heat on the SCREEN itself, AND YES IT CAN GET warm.

At 2 mins 4 seconds on this video, we have the thermal pads that make contact with the chassis?

Here we have an issue that Sony may have forgotten, Thermal pads ARE GOOD YES, as they apply a cushioning effect, however they are NOT as thermally efficient as a HIGH viscosity paste (im speaking of paste to the consitency of putty, IC diamond, Shin-etsu X23 775 (since shin-etsu is a JAPANESE company, then they should know how much better it is than other cheap thermal pads), Thermal Grizzly and the like) so automaticially we have a few degrees of loss in efficiency there by the use of pads

Why I addressed a high Viscosity paste:

When you have two surface contacts that transfer heat from one to another then over time the liquid binders of low viscosity pastes-such as; The rather rubbish and out-dated Artic Silver 5, will evaporate-from the heat- leaving what is called FREE SPACE HOLES, where there is no contact at all between surfaces.

HENCE WHY PLAYSTATION CONSOLES and generla laptops have to be repasted as the default paste used even on PLAYSTATIONS is too thin and the liquid binders evaporate due to the closed heat environment.

The main point and from looking at the tear down video, i can see an issue

THe contact points are NOT flat against each other-thus creating a thermal transferrence issue and are not large enough to enable heat to transfer efficiently to all parts of the metal frame in order to effectively make the metal fram a LARGE heatsink.

To further demonstrate this we overclockers have similar issues with AMD and intel CPU'S

INTEL 's CPU'S are NORMALLY concave (they are never totally flat-unless lapped) and if either a CPU heatsink or WATER BLOCK is flat then we instantly create a point of not contact in the centre.

To demonstrate this theory, here is an old graphics card I took apart-clearly showing free space holes

To sum up, I think Sony phones can be improved by improving the contact area by connecting to the metal mid-frame.

Make sure that BOTH CONTACT points are flat against each other and there is adequate pressure between the two.

btw this was a scratch build of a triple loop water cooling system i did, some ten years ago.

A wee bit unfair from the guy, ok he has a faulty phone, lots of people do, get it replaced and its fine.

But what I did find slightly disturbing is his lack of camera skills, i.e: the video footage that he took, was far and away better than his stills, like if you took a screenshot of his outdoor path shot, and his path picture, the screenshot looks better.

Your shots look nice as well.

I do find the catch and release view a bit narrow, as everyone here will have had a faulty item from time to time.

No overheating here yet, and thats tanking hour upon hour of video capture and playback, and game play, on games and emulators.

As long as it never gets as bad as the LG G2, I'm sure we bought my son..after about 15 minutes use, that got so hot you couldn't hold it, eventually it burnt itself out, and we had to bake it in the oven to get it to come on long enough to get his data/pics, etc off.

Yes, I told him many times on his video that he had a faulty phone 

I do think the heat I feel. On mine screen only and then only slightly warm is better managed by using better contact techniques. 

BTW yes his videos were awful 

[RottenFoxBreath]

Of course, theres no such thing as too too little cooling.

I know it gets warm, but have never had it hot.

A very polarised view he has, [Sarcasm ON]and going on "youtubers" pulling power, that could swing sales negatively, and could also be responsible for causing mass panic amongst owners whos phone gets slightly warm![]Sarcasm ON]

I agree in that a lot of Youtube reviewers and self-described journalists don't have the knowledge or capacity to give proper, unbiased reviews. Half the time they don't even know how to use the **bleep** phone in their hands or they are simply shills bought and paid for by Samsung. 

[Gilgameshuk]

hahha bud im a yorkshire tyke, not from the states and as such there is no need to sign post humour!

[Gilgameshuk]

\Oh i agree on that, most of them are samsung stooges

[blegs]

Im using xperia 1 and i dont haved trouble like him

This problem i had before when using samsung s10. Becoz i set to copy the backup from my last phone. And my samsung is very hot and acting weird

Buy after i fresh install that symptoms is gone
