High-end smartphones might need insulation as well as cooling in the future: new report

[Redaktion]

The processors that power our phones have become so powerful that they are now designed with the kind of cooling historically only expected from high-end PCs. This involves heatsinks, thermal paste and even vapor-chambers on a mobile scale these days - to such an extent there are now signs that insulation might also start to play a role in next-gen phones.

Hopefully, that will mean an end to cheap aluminum foil phones and back to high quality polycarbonate instead. Well, unless you want your phone to burn you.

Well, you can use it to control hot spots. However, unless there is a medium flowing through into which you can dump the heat, surface temperature correlates with power draw. The only thing using a less thermally conductive material achieves is increasing die temperature for any given surface temperature. So yes, if you have a glass back with aluminium frame, you could try bringing the temperature of the frame down and more in line with the glass back. But the back would have to get hotter to compensate (the heat has to go somewhere) and die temperature would go up as well. It could also mean higher operating temperature for the display. If you want to go beyond ironing out hot spots, you have to reduce power draw and therefore performance to get a device cooler to the touch.

What about iPhones? Looks like there is none.

iPhones do not need such elaborate cooling as they do not require such power. That's why so many people stay with Apple once they try them and just need to phone to work for more than 2 years without excessive customization options.
I still wonder why Android phones need so much core power and ram amount while iPhones work the same or even a lot better with half or even less that amount.

Android doesn't need 8+ GB of RAM. It's pretty much just marketing. Of course, not all flavour of Android are equally frugal. It's especially funny when large RAM is combined with aggressive memory management (for the sake of lowering power consumption) eliminating probably the biggest benefit for end user - applications staying alive in memory.

Talk about nonsense. Just compare the heat profile of iphones to android phones, they run hotter and are heavier due to all the cooling put in there. iphones also have shorter battery life then many android phones.

The difference is that Android have more power users who will push the phone to the limit.

As for ram usage, I'll remind you most android tablets have been stuck at 2-3gb ram and work just finr.

See how stupid people like you buy iPhones? You're so stupid you can't even read the article. It talks about high end premium Android phones for very demanding tasks - typically it means for gaming.

Most Android phones don't even need any elaborate cooling solution because not everybody plays the most demanding games.

Oh and not that idiot i-Sheep like you would know anything about it anyway. Because you can't install any games at all anyway except Fruit Ninja. Your stupid iCrap iTunes doesn't even have the best game titles - No Epic/Fortnite, no Google Stadia, no Nvidia Geforce, no Microsoft xCloud etc, etc,

Go back to your corner and suck your thumbs playing Fruit Ninja, chump!
