At 116F you would require firm, continuous contact for more than 20 minutes to produce a 2nd degree burn, and over 45 minutes to produce a 3rd degree burn.
So one semi long YouTube video is all it would take to get a burn? And you’d not even need a full length movie to need a trip to the hospital?
I get that these aren’t “instant” burns, but this is still a device people regularly hold for hours a day. And if you don’t realize it’s heating up, you’re likely to notice only when you’re in pain.
Yea I think that when something is hot enough to cause burns, even when it takes minutes, I think it's uncomfortable enough for people to let go way WAY before anything bad happens. If you don't then you probably need medication for whatever condition ails you
He skipped 1st degree burns. Those would probably take 10 minutes or less.
If the temp increase is slow, people don’t realize it’s hot unless they happen to put it down or reposition it.
When my son was younger, he burnt his legs by using a laptop on his lap. It got hot, he didn’t realize.
Same concept as being in the shower and very slowly changing the temp until you’re showering in fully hot/cold water.
Ironically, a frog would actually jump out of the water if its temperature slowly increases.

Realistically speaking, since this is in fast charging only, and most people don't let their phone battery drain to 0, I think it's unlikely that 3rd degree burns will be an issue within reason. The iPhone 15's reported to take about 30 minutes to charge from 0 to 50%, so if I assume the other 50% also takes 30 minutes, then really, someone won't be hitting 45 minutes unless they're charging from below 25% to full.^[I know charging isn't actually linear progression, but I don't really wanna do the math.]
That said, 3rd degree burns may be an issue once you slip a case on it that insulates the phone, making it yet hotter, and 2nd degree burns will be more of an issue too. I'd be interested in seeing what the peak temp is during fast charging with a case on, especially one of the thicker cases. If it internally gets to more than 140 degrees Fahrenheit, there's absolutely risk that it could explode, and even if it's not doing it externally, internally it may be nearing those temps.
Or maybe let's not trivialize a defect that can cause 2nd degree burns making them look like nothing?
Chill Maalus, I'm pretty clearly addressing 3rd degree burns, and only even mentioning 2nd degree burns in circumstances that are likely to increase their risk.
What part of this set you off, genuinely? Was it the reference of it as a risk? Was it that I actually looked at the facts? No part of me thinks this is good. This is very obviously and inarguably unacceptable, and no part of my post states otherwise.
Funny too that you ignore the post right next to mine that legitimately is minimizing it.
"chill dude it's clearly addressing the meat being charred and falling off the bone, and only mentioning potentially life threatening blisters in passing".
I mean, I didn't have anything to say with regards to the 2nd degree burns, really, so I didn't feel the need to comment on them. Didn't know any reply I made had to both acknowledge everything I agree with as well as make comment on what I feel was comment-worthy.
So I'll start now. I disagree with your lackadaisical portrayal of me. Neither is it accurate nor does it form a coherent argument against me. It simply acts as an ad hominem used in the place of a substantiated or communicated argument.
I agree with nothing in your non-statement.
Also characterizing 2nd degree burns on the hands as potentially life-threatening was irresponsible of pseudo-me. Pseudo-I shouldn't have done that, as it's untrue. Pseudo-me should know they're severe and serious, but something doesn't need to be described as "potentially life-threatening" to be severe and serious, and in fact, pseudo-me should be aware that this is a minimization of things that don't kill you but severely impact one's quality-of-life, as 2nd degree hand burns would.
Read up what 2nd and 3rd degree burns even are, then we can talk.
I can't say I actually want to talk to someone who takes me in the least favourable light possible, and goes off at me over their own misunderstanding.
Over whose misunderstanding? It was you who doesn't know what second and third degree burns are.
Complete opposite. I've never seen any other group of people let their phone drop so low. It's like they do it on purpose. I blame the lack of battery % so they don't get the anxiety effects.
What about 1st degree burns? Would these be ok?
