It's mind-blowing how slow the advance of batteries is compared to every other kind of technology

Battery tech has the limitations of chemistry to deal with. A ton of cutting-edge work is being done with exotic materials, but it needs to be ready for the mass market before we see any groundbreaking improvements.
Not every other kind of technology though. I think the problem is that batteries get lumped in the same category as "modern tech" (e.g., microchips and storage), rather than with energy tech.
For example, Wikipedia says a post-war VW bug got around 35mpg. That's similar to the combined mileage of a Civic that's 50 years newer. Yes, the Civic is more powerful and weighs more
but we're not talking Moore's law improvements.
Same if you look at power. A 1967 Corvette 427 was listed at 430 horsepower; a modern base Vette is 490 (or 670 for the Z06). Sure, the mileage is way better, etc., but again, hardly Moore's law improvements.
Energy and power are tricky.
The 67 was measured with no accessories or load. It would be about 350 bhp today. It also had ledded fuel that would be like running on only e85 and with no cat today. If you had that the Z06 would be well over 1000 hp with the old rating.
I mean sure, but it’s also kind of the opposite. Energy density has increased dramatically from lead acid technologies.
The real issue is you’re not going to leave leftover power untapped, so the tech will always exceed the battery as they try to leech every last drop of power from the system.
Sorta like an energy chicken and an egg situation.
More like Apple is slow to advance their battery size. Samsung is offering like, 5000mAh batteries in their A series phones (Hyperbole yes, but still)
Optimization is more important than just sticking a larger battery somewhere.
Besides bigger batteries make phones heavier pretty quickly. For mobile devices, optimized system and apps is very important.
Ehhhhh, when your making a completely integrated device, Optimization is the core. And, an iPhone with a 5000mAh+ battery would probably last 2 whole days.
Idk what phone you have but my 13 pro easily lasts 2 days for me, light usage I could probably get 3.
I’d welcome this. My ancient moto phone had a 5000 mah battery in it and is thinner than my iPhone 13. Idk why they haven’t crammed more in before now.
I see that the source is unproven but if true, I’m happy for these changes. That said, I really want this phone to be much lighter. It is noticeably heavy. Let’s get rid of the stainless steel on the Pro.
I like the weight. I’m not a fan of the ultra lightweight design. It feels to fragile.
Requesting a iPhone 15 cast iron version.
c/CastIron will go wild>
“Seasoning my new iPhone 15 Pro Max CastIron 100 times”
“Guys I know the instructions say I can use any odorless cooking oil, but is there anything wrong with just buying the $89 Apple oil? I want to have a matching set”
Only if you rub it in with the Apple Seasoning Cloth.
