iPhone 15 Pro Likely Feels Even Lighter Than It Really Is Due to Inertia Change

The "moment of inertia" stuff is correct, but does make it sound a bit technical. Thinking in terms of "centre of gravity" and leverage is probably easier.

Think of a ball of lead that fits in your palm, so all the weight is supported by your palm.

Now think of the same weight of lead beaten out into a foot-long stick, that you hold by one end, so the centre of gravity is some distance from your palm and is trying to bend your wrist.

For a phone, concentrating the weight in the area that is usually supported by the palm of your hand (typically the centre of the lower 2/3) should make it more comfortable to hold.

No.
Center of gravity is a different property than moment of inertia. There has been no indication that the center of gravity is any different than previous iPhones. The center of gravity is most likely still pretty close to the center of the phone. It is the distribution of the mass with respect to the center of gravity that has changed. Essentially, in the iPhone 15, the mass is more tightly clumped around the center of gravity.

Your failure to understand the concept does not make you right and your use of a snarky, worn out, and unrelated meme to express your lack of comprehension does not make you clever.
Not that I care or expect to change what you think. I’m only posting this reply in hopes that other readers will not be mislead into ignorance by your post.
The original article is technically accurate and makes a valid point. It is a matter of individual perception how consequential that point is, which I think was amply clear from how the article was written.

Science!

The bulk of the weight is still the camera lens so unless there’s some magical counter balance act going on phones will always feel heavier towards the camera systems.

Came here to say this… it’s a pity there’s no easy design solutions to move that heavier side to the bottom/palm of the phone. It always feels a bit top-heavy, like it just wants to fall over your fingers and out of your hand.

That’s one of the reasons I love the MagSafe wallet. It adds lower weight for balance, and gives a softer, curvier feel to the back in your palm. Also you can lay it flat on its back to be completely stable and raised off the surface (not resting/wobbling on the cameras). I’ve been able to switch to going without a case because of the wallet.

Well, better get a grippy case in case the ever so lighter iPhone learns how to fly…

Spoken like a man who loads the Coke Zero 24-packs and other heavy items into the back of his grocery cart.

Nice catch! The number of negative reactions confirms many people lack the ability to comprehend nuanced information and have a tendency to dismiss it (if not buy into contradictory disinformation or whatever they'd like to believe).

No, it only shows that a lot people don’t appreciate how ‘nothing’ (‘cause that’s what 20 grams ‘improvement’ is: nothing) is being framed as a major improvement. Even by invoking scientific claims that it really is worth your 1.200 bucks.
Apple’s shareholders, meanwhile, sit back, laugh at that nonsense, and let their dividends flow into their pockets.

Great news. I always liked the weight and the size of the X/XS/11 Pro the best, but this is a good compromise. I’ll take lighter any day of the week, since phone is in a case, anyway. Plus stainless steel is a fingerprint and scratch magnet.

Oh please. When you are forced to take the larger storage option if you want the Pro Max, that’s a price increase. When I MUST spend more money to buy the equivalent model this year compared to last year, that’s a price increase. When more money is charged to my credit card when I buy a Pro Max this year compared to last year, that’s a price increase. Shall I continue?

I bet, if Apple released a 128gb model for the same price as the 128gb 14PM, you would complain that Apple are still releasing low memory options and people should go for the 256gb version!

They should only release 256G and up. But if they raise the price like the 15PM (base), call it what it is, a price hike, because that's what it is. Even my flip 5 came with 256G, and it doesn't need as much storage for its picture capability.

What are these comments I'm reading? It's just some simple explanation as to why the iPhone 15 feels lighter than the reduction in weight would seem to suggest.

To those thinking this is why the iPhone is more expensive this year, I'm not sure what your train of thought is here. I would think Apple went in with the objective of reducing weight and the best area to reduce weight was changing the heavy steel frame. The internals and battery can't really be lightened easily. The fact that reducing the weight of the frame has a bigger impact on moment of intertia than reducing the weight of the internals is just a happy coincidence.

Imagine Apple described all their new product advancements in this way. The September event would still be going!
