Apple Says Pro Display XDR and 2021 MacBook Pro Can Experience Limited Brightness in High Temperatures

[ohbrilliance]

Heat must become a real day-to-day issue when using Apple and other electronic devices in hotter parts of the world.
I found that my iPhone XS refused to charge when the ambient temperature was 35 or more (95F I think) and resorted to put it in the fridge while charging. There are plenty of places where those temperatures are common.

The problem isn't with the caution/warning. It is basically the lack of proper science education for most people out here. In order words: dumb people don't understand basic laws of physics. The lack of proper mathematics and science in the USA is just ridiculous.

There it is, the stupidest thing I've read today.

What you posted is so incredibly wrong on every level.

If US math and science education is so awful, why is the US one of the most popular international education destinations?

And how does science education even apply in this case? Do you have some special knowledge of the materials used in the Apple displays that you can accurately calculate the acceptable operating temperatures for the panels at a given brightness level, or are you just talking out of your ass?

This is unacceptable. I’m boycotting Apple and their products. Who is with me?

?
?

 

[Wackery]

I do not blame them. Running something demanding for longer period of time and also watching some HDR content at 1600 nits and that thing will get hot The same as iPhone and everything else.

Here come the apologists for the ‘pro’ machine

Here come the apologists for the ‘pro’ machine

So you run your laptop (regardless of brand) at full brightness all the time?

If you would've actually READ what apple said, its running the screen at full (1600 nits) for multiple hours under warm ambient temps that will cause the caution sign to happen.

It's nice when one reads the actual article instead of spew nonsense for no reason

It’s a design flaw. The laptop is too thin, let’s make it bigger to prevent any overheat! 2lbs, 10 lbs, doesn’t matter, power that what matters ?. Apple, please be consistent!

 

[wanha]

WHAT?! Are you telling me I won't be able to use a MPR in a hot sauna at full brightness?

Apple are clearly losing it. Time to close shop, Tim.

*sarcasm*

Comments like this is why the "ignore" button on these forums was invented.

And I hate it so much on the iPhone.

I usually get the too cold warning on iPhones. iPhone don’t work too much below freezing, which is common for my use.

 

[zyxtaxbo]

Good to know, that apple built in some sort of protection to these precious displays.
Otherwise, they could just let those displays burn to death (led degeneration) or they would have to put a fan somewhere.

 

[nt5672]

Let's face it, if you are developing content for use in Apple devices you should just be working in a cave with a constant 55F. That way you don't tax Apple design engineers into designing heat dissipation capacity that has been an epic failure in Apple devices since forever.

 

[mikethemartian]

Well I keep my rooms under 10°C so I am sure it'll be running good most of the time. Except maybe in summer where there is nothing I can do to keep the house under 15°C.

10C. I thought I liked it cool at 21C/70F.

I think you have to differentiate between the university level and secondary education level.

 

[CosmoCopus]

Great, now they brought the problem (feature) of the iPhone screen dimming when hot to the desktop.

…and the notch too.

 

[tekmoe]

I never need to run my brightness at more than 50% most of the time. I’ve also never seen this happen since acquiring my M1 Max back in December. Nonetheless, it’s a good thing to know just in case. Thanks Apple!

 

[InuNacho]

Wasn't the era of ARM supposed to free Apple from their Intel overheating shackles?

Glad to see things don't change!

 

[Hexley]

This is such a reasonable response that I had to check if I was on MacRumors forums.

 

[Alpa7000]

It‘s common on fanless HDR display,but some SDR displays like Huawei MateView will limit brightness in 10 minutes

 

[l3it3r]

Today in ‘duh’

That said, my 2021 M1 Max 16” has never dimmed and I use it for 6-8 hours basically every day.

Yeah, no one ever uses their screen at full brightness because apple told them too ?

 

[aevan]

Only ever got the caution symbol on an Apple device once, and I knew I was torturing the device under direct sunlight in sweltering heat. This is a reasonable precaution for extreme situations, and it’s clear it doesn’t get triggered easily or often.

Yeah, I never saw this even though I watched entire HDR movies with maximum brightness. The fans did turn on after a while though. I'm glad this option is there.

~30 Celsius / ~90F

30C is closer to 85F (86 to be exact)

 

[clevins]

My room temperature, as I type this message on Macbook Pro 14', is 33C. So far so good. But I never set brightness above ~60-70%. No problem thus far

Precisely. So many people are whining about the 25C/77F thing but it's that in combination with running the screen at or near full brightness. Which is insanely bright.

 

[obamtl]

77F is what, 25C? That must be a joke! Hardware that doesn't work properly above 25 degrees?

Yes, I understood. It is not considered a fault if it drops the brightness when above 25C. That low of a temperature limit is a joke. My point stands.

But it's not saying that it isn't a fault if it happens above 25oC. Just saying a circumstance where this happens below 25oC is a fault.
