"My phone is really hot, is this normal or is it broken?!" is something I started getting asked by random iPhone-using friends over the last few years as they upgraded to a new model and then felt it sizzling.
But even then it was no hotter than my 16 Pro
I have one, too, and you're right that the heating is just what happens while it restores its data and settings and whatnot.
I believe it also re-scans your entire photo library to re-identify dogs, cars, people, etc. with whatever improved algorithm comes with the new chip/OS.
This happens every time you get a new iPhone. Depending on how much it has to sort through, it can take a couple of hours to a week.
I always leave the case off for the first few days.
One less core, and from the benchmarking it's clear that it throttles a fair bit earlier than the rest. Even worse its a titanium body so worse dissipation

I'm guessing phone cases are still pretty much required if you drop your phone once or twice a month onto cement/asphalt/marble/etc from pocket height.
I would be really curious to hear the internal debate at Apple wrt design tradeoffs + durability. E.g. how much of the iPhone design is only possible because Apple is assuming the average person will have a case on their phone.
I wouldn't be surprised if the typical consumer would be more impressed by "No Case Required iPhone" compared to "Skinniest and lightest iPhone yet!".
…you don’t. I don’t. My phone is scratched here and there, but not in a way that I notice. I used to defend this with my purchasing of insurance, but frankly, I crack the screen now maybe once every 2+ years.
> Apple is assuming the average person will have a case on their phone
I think it is fair to assume that irrespective of the design, most people will case their phones. Leaning into that is fine as long as the phone is still functional without a case. (Which, again, every iPhone in the last decade has been.)
Agreed they're functional without a case.
Whether it's functional after dropping it face down on the glass onto cement/marble is another question!
I'm not too concerned with cosmetic scratches. The main issue is the screen shattering. And the back of the phone shattering in older models where the back was glass.
Confirming it is. Source: clumsy as hell.
The glass is sturdier and more scratch resistant than it was ten years ago, when I was smashing an iPhone screen a couple times a year with a case.
For my phones, I use the cheapest most-featureless blackest thinnest TPU cases I can get my hands on.
They tend to [just barely] cover the edges of the glass screen, they're very inexpensive. They never seem to wear out in any appreciable way.
So far, zero broken screens in the ~16 years I've been carrying these pocket computers absolutely everywhere...and I drop them about as often as anyone else does, I suppose.
If the screen were reasonably scratch + shatter proof, I think most people wouldn't feel the need to wear a case.
Last time I broke the front screen of a phone was an HTC Evo.
So it seems like the screens are not easily broken anymore. Though that event did lead to me using a case on my next phone just to avoid chancing cosmetic damage on it.
Here's a patent for the idea which just expired this year: https://patents.google.com/patent/US7059182B1/
Apple also patented some versions of this, although I think not as nice as the 2005 one: https://patents.google.com/patent/US9571150B2
https://en.wikipedia.org/wiki/Sudden_Motion_Sensor
Though I don't recall iPods having that feature, nor can I find anything online supporting that claim.
Lenovo/IBM have a Free Fall Sensor in the laptop.

It is a bit bigger with protective shell around it is bulky, but withstood all the drops that a typical phone would break. There is some flaring around the screen and camera that it prevents most of scratches. The back has some sort of hard rubber but it held up well.
I've only had to replace the screen protector within 3 years as the scuffs and marks made it difficult to see in well-lit environment.
Because the iPhone 15 pro was significantly lighter than previous pro models, I wanted to avoid a case to get the most out of this improvement. However, I wouldn’t have even experimented with not using a case if it weren’t for the applecare+ plans that are reasonable. I’ve been surprised by the durability to the extent that I should probably discontinue the applecare+ plan.
The aluminum models might not be as durable. Compared to phones 20 or even 30 years ago that didn’t need a case, I suppose a significant difference is the density as much as the total weight or the hardness of the materials.
But modern smartphones are anything like that, and people do like the more premium materials on the outside (and it sort of makes sense - if you have a device that you are using 24/7, it might as well "feel" more premium), so I don't think it's a fair comparison
Having a sacrificial outer layer that I can replace for $10 is also preferable to letting the $1000 phone take the damage.
I went caseless once since I didn't realize my case would arrive a week after I bought the phone.
The phone was slippery (couldn't temporarily rest it on my knee), and I found myself inspecting the restaurant/bar table any time I put the phone down after that one night I placed it right into a puddle of beer condensation and some mysterious food that got in the mic on the back of the phone and grossed me out.
The phone could be indestructible to drops and it still wouldn't solve those issues.
The Air I might consider putting a bumper case on since its thinness offsets the bulk increase, but it's specifically made to be resilient to drops so it's a coin toss even with that.
I barely drop my phone though, it happens maybe twice a year, usually on carpet. In the last decade my phones might've had a run-in with concrete or pavement 2-3 times, tops.
Even for one year that's more than I'd spend to avoid using a phone case, and if I keep it for five years again that's $700.
There are other benefits to AppleCare (a case doesn't cover theft or loss) but I'm not very worried about any of them.
That's why I use an aramid fiber case from AliExpress. It's paper-thin, but has saved my phone from more drops than can remember. I used to go caseless, but since trying out aramid I don't see any practical benefit to caselessness.
Before that, I was using this one from Thinborne: https://www.amazon.com/dp/B0CHLF8FD7. For all intents and purposes, they're functionally identical. I slightly preferred the style of the AliExpress one (camera glass cover + no logo), but the main reason I went for AliExpress when I needed a replacement was that it was half the price of the Thinborne. (The AliExpress one has since gone up ~$10, but the Thinborne one doesn't appear to be available at all anymore.)
A $1k phone SHOULD NOT be a frictionless glass prism. It should not skate away from you ob smooth surfaces. It should not be destroyed by falling 3 inches onto a hard surface. It should have some durability inherent to it.
But instead apple spends billions of dollars making phones even more fragile and it's everyone's problem. We now have to spin up factories processing plastic into custom cases, and throw out all the old plastic cases and the older, more functional phones.
The argument is that phones could (and should) be inherently more robust and durable all on their own. It should not be a hard requirement for you to go out and buy your own case just for the phone to survive any level of daily use.
If they made phones out of plastic instead of glass, this wouldn't be an issue. Plastic backed phones almost always have a texture and when they don't even smooth plastic offers more friction. Plastic phones don't slide away like they're on ice. They don't shatter like my Note 10 did when it slid out of my pocket two inches to the ground. They also don't usually self destruct when you repair them.
The caseless argument isn't that cases suck, it's that we MUST use cases because phones intentionally suck. A phone is not a functional object, it's artistic ego masturbation.
But 99% of people won't like the solution where this has to work out of the box
Every moderately "needs impact resistance" in the prosumer/professional sector either comes with a case, or has a "builtin" case, making it thicker/heavier. Just search for 'Cat mobile phones'
A grain of sand will scratch most metals and most glass surfaces, even hardened ones. If Apple managed to make this more resistant props to them, but it is not infallible
Vandalism resistant electronics are thick and have glass/polycarbonate/acrylic combinations that don't look good for the most part but will take a baseball bat like a champ
It's a cheap sacrificial shell that adds utility. My examples were non-slip and grime from a public table. Maybe add scratches and impact damage in there too because every material is susceptible to that, and avoiding them helps me resell it.
There's no way to build that into a phone. I don't want rubber non-slip bumpers on my phone or a built-in clawed up plastic shell when I can have them in a swappable shell.
I don't see what's the big deal honestly
Some people just seem to like making things harder on themselves
Meanwhile if I drop my phone (which I'm very careful, so it was probably once or twice and not from too high) it's really nbd
For my 17 Pro I got a case with a kickstand. If the kickstand breaks off I get a new $16 case. If it was built into the phone I’d possibly need a new backplate depending on the damage. Probably not $16 to fix. A built in kick stand would certainly become a love it or hate it feature based on how people use the thing.
And there are people out there who are going to be huge fans of the Flower Power iMac. They can get just such a case and Apple doesn’t have to take the loss on that given 2025 design aesthetic .
I really wonder, seems like maybe, and might be worth looking into. If so, that would be fantastic and would make the case round to 2 orders of magnitude less costly than the device, instead of just 1.
Do cases guarantee your screen won't break if you drop your phone? No. Do they dramatically diminish the likelihood of cracked glass in the most common scenario of phone falling on flat concrete? Absolutely.
Some of us are harder on our things than others...
I do like some cases for their design elements, I might use one to just further personalize my phone.
I usually drop my phone 3-5 times a month. Inexpensive cases and screen protectors have saved me quite a lot of hassle.
Fewer repairs saves time, produces less waste, and preserves more of the resale value.
Almost the same here. We got new identical phones in 2023 for a good deal because they were made in 2022.
She breaks hers fairly regularly and myself not at all so far.
I guess they are considered obsolete already because in our complex there was apparently someone operating a cellphone shop who was discarding a couple dozen assorted brand new cases for this exact phone!
Fancy ones, tough ones, light ones, some with kickstands, quite a variety.
None of which I could abide for very long. She loves the most fashionable one.
Then one day I found something I could use that was made of a space-age fiber I have been long acquainted with, rayon.
It was an ankle sock, and it was not one of hers.
Pretty much useless by itself as footwear, so it existed for a time as orphan laundry before I tried it.
Uncased phone doesn't fall out when you handle it upside down, but slips out real easy when you want it to. Plus you can see who's calling through the fiber without having to remove it beforehand.
It surprised me that people seem to show more interest than they do for more fashionable alternatives that are not even footwear at all :)
The point of a case is to avoid having to pay for those repairs.
deep scratches are trivial and drops will immediately lead to heavy dents. that being said the screen itself is incredibly tough so it will be usable.
before (stainless / titanium) you could go caseless without concern. the most i ever had happen was a little crack on the back
Maybe the new phones are better, but I was quite disappointed when I noticed how easy the paint came off. What's the point of a pretty phone if you're gonna need me to put a case around it?
If you're curious about just how durable the iPhone Air is, take a look at the latest Jerry Rig Everything video where it exceeded his typical scratch test resits and he was unable to bend it with his hands.
https://youtu.be/sQ56ve39l2I?si=XOgAtnlAtOwO4Lln
> Typical smartphone glass starts scratching at a level 6 on the Mohs scale of hardness, but Zack’s picks barely left marks even at 7. “Apple ruined my line,” he joked, noting that Corning’s new Ceramic Shield 2 is a big improvement over last year’s iPhone 16 lineup, even besting the Galaxy S25 Ultra’s Gorilla Armor 2, which showed visible scratches at a level 6 when it was put to the same test earlier this year.

> Using a crane scale in his garage, he applied direct pressure in the center of the iPhone Air until it finally gave way. The iPhone Air endured up to 216 pounds (~98kg) of force before its front glass finally cracked and the titanium frame flexed past the point of recovery. Surprisingly, the back glass came out unscathed, and the phone was still powered on and usable in the end.

Also, i find it nice that they decided to honor they allegiance pledge to the regime with an Orange model. It was a nice touch.
Sure I have some scratches on the screen, but so what? If the front or back glass shatter, it's $29 to fix.
Because of the above, I don't think there is anything (reasonable) smartphone manufacturers could do to make people feel like they shouldn't add one just in "case".
On average, I keep the same phone for 3-4 years (current phone is an iPhone 11, coming up on 6 years old).
I started using a silicone case with iPhone 6S as found it was slippy. Have a leather case for iPhone 15 Pro but considering going naked again.
(I walk a good deal and also bike with the phone in my pocket, so it's possible my phone gets above average wear in this department.)
You can buy a $400m yacht and still need buoys when you dock it.
Unless you want a phone that comes with a pre-installed rubber bumper around the outside, or we have some humanity altering discoveries in transparent materials science, you’re always going to have a case. Gravity and concrete are undefeated.
Sure, why not? If there's going to be a rubber bumper anyways, why wouldn't I want the manufacturer to ship it?
In 25+ years of carrying a naked mobile phone everywhere I've never broken one. My lifestyle theoretically exposes me to significantly greater risk of damage than the average person too. I view phones as semi-disposable devices, so I take no special care or precautions.
I am eternally baffled as to why people need cases on their phones. The observation that many people do seem to break them frequently isn't an explanation. I can't wrap my head around the degree of clumsiness and carelessness that would seem to be required to explain this phenomenon.
At some point, you have to conclude people don't actually care if they smash their phone based on how frequently they do it.
As I said, it's baffling.
Heck, even when I think I'm being careful (eg carrying a very full mug or glass), I'm liable to focus on what I'm doing to the point of messing it all up due to lack of awareness (eg keeping my glass nice and still until I bump my elbow into the door frame and spill some of my drink).
It also does not seem to be improving wit age.
The fact you’re baffled that accidents happen makes me question if you’re trolling or literally live in a bubble.
Have you considered that for other people phones are a significant financial investment?
I’m not regularly smashing my phone or especially careless with it, but in a year I’ve seen it take a dozen or so drops and I’m glad it had a case on it when it did.
How do you explain the contradiction of people who go through the pretense of protecting their phone then engaging in behavior that somehow smashes it regularly in a way that demonstrably cannot be explained by normal usage? There is an entire population of no-case-enjoyers who don't smash their phones despite the lack of extra protection.
If you’re going to include the pre smart phone era of mobile phones in the discussion, it would be nice to let people know
By the time the iPhone was revealed the Sonys at the time made Apples look pretty dumb by comparison.
Sony had regular ordinary quick-change batteries, at least their own Memory Sticks for removable storage before they ended up settling for SD cards, plus the essential USB connection in addition to bluetooth to connect you to your PC to at least use the PC OS to handle the file management of the phone.
And there was always the PC software suite for Sony owners so you could get your PC online before there were hotspots, and you could do texting and make calls from the PC, update the phone, install phone apps from the PC, etc. You could consider the phone a peripheral of the PC, or the PC a peripheral of the phone. And integration was supposed to continue getting better from there.
Like a normal smartphone way before the iPhone appeared, which the iPhone had none of the established hallmarks of smartness, except that it was on the internet. Plus it was locked down in annoying ways never before seen.
Jobs was pretty intense with his reality distortion efforts, he got people to believe until this day that smartphones didn't exist until he had success with it. What it really was was that established smartphones were about $500 and almost nobody was going to pay that so naturally they were not flying off the shelf any more than they ever had been. It was actually widely considered pretty stupid to pay that much for a phone at the time unless you were deeply in need of those connected features.
He convinced enough people that phones had never been so "smart" since there were so few having any experience with them. But why stop there? While he was at it he got his fans to pay almost $1000 too.
That's my go-to right there.
I'm old enough to where I won't be forgetting any time soon how excellent things can be without any phone at all, much less cellular. Land lines were usually too expensive for students but people weren't crying about doing without.
I do bring the flatphone with me regularly, just not most of the time, and only when I have a strong anticipation of wanting or even needing it.
In a restaurant I didn't even like pagers when they were a thing.
Pagers might have been anti-social with their piercing interruptions, but least they weren't as annoying to carry around as an oversized internet-connected device.
And definitely not as anti-social as a phone having Facebook with a human being strung along attached by the finger.
Thickness? There are a lot of thin cases that will do the job.
Heavy? Better to invest more on arm exercises if that weight is dealbreaker
Status symbol to show off? There are better things to buy if you are in that sort of thing.
Just because you’ve never damaged a mobile phone, doesn’t mean that no-one else has. Mistakes happen, and modern mobile phones are fragile and dense.
I tried rocking no case and broke the screen which isn’t a huge deal but required attention, downtime, and the phone didn’t work the same way after repair.
I mean... yeah? What consumer tech is that resilient? Maybe put a lanyard on the your phone and attach it to your belt, I mean..
They could make a toughbook style phone for people with such habits, but engineering a mainstream device for such resiliency is going to be overkill for most users and cause a lot of tradeoffs in size/cost/features.
I'm a person who tends to accidentally throw my phone around a lot, and don't use a case (cause the added bulk makes me throw it around even more). Often on ceramic tiles, often with added velocity from me walking or hitting it in the air while trying to catch it.
My iPhone 13 Pro still survived 3 years, and only had some scratches and bruises on its corners, but nothing broke (still in use, by someone else now). My iPhone 16 Pro after a year of that same treatment is almost unblemished (a small bruise on one of the corners).
These are, in practice, extremely resistant to damage.
