Phones don't handle heat well. I was outdoors the other day trying to take pictures while it was 90-something, and my phone had to cool off in between shots before it would let me use it again.

When the outside temperature is almost as hot as the phone itself, air cooling doesn't do anything

[–] SkyeStarfall@lemmy.blahaj.zone 15 points 1 year ago (1 children)

Hardware components (at least the ones that produce the most heat) are built to withstand over 90C for desktop computers, for devices with bad thermals (such as phones) they tend to be designed to withstand above 100C.

Air cooling would help a lot, even for 50C weather. It's just less effective the warmer it is.

Does it? A fan isn't actually cooling anything, it's just speeding up natural thermal exchange, drawing hot air away and allowing cooler air to take its place. If there's no cooler air available, I don't see how a fan would be of any use.

I know that when my room is just a few degrees C warmer, my CPU runs hotter and the fan runs higher for longer.

[–] SkyeStarfall@lemmy.blahaj.zone 7 points 1 year ago

As long as the outside air is below like 80C.. yes it will help.

Hardware runs hot. More air circulation will help in nearly all instances in practice.

[–] Tyfud@lemmy.one 2 points 1 year ago

Yes, it helps. The parts that are being air cooled are substantially hotter than the ambient air, almost always, do the faster you can circulate air the faster they will cool down, even if it's relatively hot outside for humans.

Well sure, because the difference between air temp and hardware temp isn’t as great. So it has to move more air to achieve the same cooling.

But it’s still cooling. If your room is usually, say, 20°C, and it’s now 25°C, while that’s hot for us it is still a LOT cooler than the, I dunno, 60°C your CPU is running at.

If your room is hot enough that the CPU cannot cool, you probably wouldn’t want to be in the room, since your body needs to regulate your temperature significantly lower than the CPU (≈37°C or 98.6°F).

I'm not sure. Those phones also try to maintain crazy framerates and resolution, so it may even out.

[–] bazsy@lemmy.world 1 points 1 year ago

I would expext to see Frore's cooling solution in gaming phones soon. And if they develop an even smaller version some mainstream phones could include them too.

[–] altima_neo@lemmy.zip 4 points 1 year ago

In fairness, old digital cameras kinda did the same too

[–] Jmr@lemmy.world 3 points 1 year ago (1 children)

One time It was 35° out and my phone got so hot I had to dip it in water

[–] Grass@geddit.social 2 points 1 year ago

One time I went to Tim Horton's, and I ate the bowl.

The EU countries should pass some laws and regulations that they think would address climate change. I know they are not the biggest polluting nations in the world, but they can't expect anyone else to do something they have not done themselves, and Europeans can no longer wait for others to change.

[–] EyesEyesBaby@lemmy.world 22 points 1 year ago

We're doing a lot more than the US.

[–] TheFerrango@lemmy.basedcount.com 14 points 1 year ago

Someone has never lived in the EU.

Are you serious?!

[–] Mr_Blott@lemmy.world 10 points 1 year ago

Please tell me you're joking 😂

Meanwhile the Americans drive around their massive trucks, live with constant central AC etc.

[–] Amir@lemmy.ml 3 points 1 year ago

They've been trying for 30 years... problem is that none of the member states are actually listening so it's a constant back and forth of "but can you pleaaaaaase start doing it now?" "maybe we'll consider in another 10 years"

[–] fantinel@lemmy.world 3 points 1 year ago

I can excuse killing humans, but killing phones is where I draw the line. Down with climate change!1!!

[–] bighi@lemmy.world 1 points 1 year ago

I think these news are overblown. There are many countries where temperatures of 115F are normal every summer, and people’s phones keep working normally.
