Aluminum and titanium respond differently to the anodization process. Titanium is less of an electrical conductor than aluminum so it doesn't anodize as easily.

Second is that the oxidation layers created by the anodization process behave differently in aluminum versus titanium. The aluminum oxide layer readily bonds to dyes so it can be used for a wide variety of colors (hence the bright options for the base model iPhones). The oxide layer formed on titanium does not readily accept dyes, but the thickness of the oxide layer refracts light in different ways and can be used to create different colors based on the voltage used. Most of these colors will be relatively muted (think of the gold and blue options of the 16 Pro and 15 Pro).

Below is an example of the colors that could be achieved on titanium depending on the voltage used during anodization. (Note the flash likely makes the colors look brighter)

Those are all beautiful colors, yet they gave us those ass colors for the 15 Pro and 16 Pro phones.
 
Nobody’s saying an iPhone is hard to use because of its weight. But if it’s something you carry all day, every day, making it lighter and less bulky is just common sense, or at least it should be.

Comfort and convenience are about improving the experience for something that’s always with you. Keys for example: they’re small and light for a reason. By your logic, should we all carry 50 of them or make them bigger and heavier, just because we’re not mice?
By your logic I should have no problem carrying 50 phones either, but that’s silly and unnecessary. I understand more than anyone the desire to carry less - I carry NO keys, I have them in Apple Wallet for this very reason. But it has nothing to do with weight, it has to do with volume.
Right now, we are at the limits of how reasonably thin we can make the phones. They are as heavy as they are because they need to be, it’s not like Apple is putting weights in them for fun.
The ergonomics suffer due to physical constraints as well. The pros have a camera bump. The Air is proposed to have an even more pronounced camera bump, and greatly diminished battery life relative to the pros.
Maybe one day there will be a new battery technology that can be equally energy dense in a smaller footprint, and new sensor technologies that can lose the bump, and then we can all have slim phones. Until then though we still have this large bulging thing in our pants. It could way 1 ounce or 20, that makes little difference.
Until the entire device is slimmed down, and not just the lower 3/4 of it, we are not going to get a markedly improved “in pocket” experience.

No no, that’s not my logic at all - don't get it twisted. That's your logic; I just flipped it into a different analogy to show the flaw (and yes, carrying 50 keys is silly, but you didn't argue they should be bulkier and heavier just because we are not mice - which was your logic to begin with).

On the contrary, my logic is that current devices are already heavy enough, and they should be lighter if possible. Changing a chassis material to achieve this is welcome, at least to me. Apple clearly agrees, otherwise we wouldn’t even be having this conversation; they wouldn’t be moving back to aluminum or introducing an Air model if they thought the current weight was just fine (assuming all this plays out of course).

At the end of the day, it’s good that there’s more choice in the market. If someone prefers the heavier, feature-packed Pro, great. If someone values a lighter, more comfortable device in-pocket, also great. The point is: weight does matter to some of us, and it’s worth designing for that too. For those that it doesn't matter, go grab what is best for you - but don't speak on behalf of everyone when you say this is useless and no one asked for it.
 
But acting now that Aluminium is bad in some way is also way too much.
Vice versa you fell also for the apple marketing in that case, in the same way your so called iSheeps falling for any advertiserd new stuff over and over again.
I personally think this Aluminium Unibody is pretty nice and I’ve never gave too much about „Steel in surgical quality“ or „Titanium with space travel quality“… this is all marketing bs.

I agree most of it is marketing bs to hype something. However, my experience is that aluminum is more prone to denting and gauging than steel or titanium. Titanium and steel are more likely to just scratch or have color come off.

as someone who only buys a pro, I can only see this as a downgrade for marginal to no improvement. What are the benefits? It’s a little lighter now, which realistically affects nothing? Shaving off mere grams of weight doesn’t achieve any significant improvement in ergonomics or usability of the device, and it comes at the expense of my phone now being made of a less durable and less premium material. Titanium was lighter than steel and very durable. They should’ve just stuck with that. And they should not be surprised when there is pushback on this change, especially after the way they themselves marketed the switch to titanium.

The TiBook commonly got dents, but much worse were the hinge failures and paint chipping.

However, what annoyed me to no end is the way they introduced the AluBooks. What I wanted was a 12” PowerBook with USB 2 and told all my friends in 2001-2002 Apple would release one. Then in late 2002 Apple released a new PowerBook… G4 Titanium 15” with USB 1, and no 12” model.

So because I need to upgrade from my G3 iBook, I bought one… only to be presented with a new 12” and 17” PowerBook Aluminum with USB 2 just a couple of months later at Macworld. And overall, IMO the AluBooks were nicer than the TiBooks.
 
The comparison to bikes is pretty on point. It’s the same here, every company advertised the used material of their bikes as the best.
At the end Aluminium, Titanium and Carbon all having their own strength and weaknesses but there isn’t that one material that is the absolute best.
Steel is the absolute best.
 
Unobtanium mixed in with Admantanium. It's lightweight, like a feather and nearly indestructible! Now thats innovation.
 
I really dont understand the overreaction here. The aluminum alloy used in iphones was designed specifically for smart phone use. It has a proven successful track record. It's been perfectly fine for years. Stainless steel is heavier, more expensive, and prove to scratches. (my iphone X used to flake off the black film on the stainless steel too) Titanium is a good material but it doesnt actually solve a problem for the iphone. It actually creates new ones by being less thermally conductive and more expensive. Titanium makes sense on a watch maybe but on the phone? its totally unnecessary.

I have a steel one for when I used to commute and a titanium one for long distances. No longer have an alu or carbon one primarily for comfort reasons but then I’m not going to sit on my phone.

I am fine with aluminum for the next iPhone, and will also agree that aluminum does provide some advantages, but scratch resistance is not one of those advantages.

The steel and the titanium with it’s coating weren’t that scratch resistant neither…

It's just too ugly to look past. Apple is supposed to be design-led. Jobs and Ives would never have released this, it has all the nooks and crannies of the 1990s beige boxes.
You’ll put it in a case like everyone else and won’t care.. so don’t worry about it. All these ugly comments about the chassis are moot when I’d be willing to bed 80%+ use a case. The other 18% will drop their phone and be pissed it’s damaged/broken, 1% will not care, and 1% won’t drop it, case-less. 🤷🏽‍♂️ rough figures of course.
 
I don’t really care that it’ll be aluminum. I’ll appreciate the thermal benefits and weight reduction. That camera bump though… baby got BACK.

And the price bump is because of Taco. Aim your ire there.

Pick a side...is it "taco" or are the tariffs in place and causing price increases?
 
With the move to aluminum, I’m less concerned about weight savings as I am about a softer, more scratch-prone device. Scratches on the softer aluminum reveal a bright silver cut in that anodization. These Ti 16 Pros are bulletproof. Mine looks as pristine as day one. And I don’t use a case.
Pro tip: acquire a sharpie in the right color. Prob solved.

Im not saying it’s bad. It’s just bad because Apple all the years claimed how superior titanium, stainless steel etc is towards aluminum, just to change back

That’s true. But if you want to nail them with all „superior“ stuff over the years, you will a lot, same goes for other companies.
That’s the usual marketing bs.
