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

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.
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 poat-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.
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.
Yeah, until they make a new kind of battery it will stay that way
The huge battery advancements have been cost to build them. I think a Tesla roadster was around a thousand dollars per kilowatt. A model three is under 100 per kilowatt now.
But the underlying technology has not changed much, if at all. The Tesla battery is nothing more than what is a bunch of Li-Ion battery cells wired together.
Bigger battery + the change to USB-C would be awesome.
Agreed, I would like to rarely have to charge and when I do need to it’s with a cable I can use with all my other devices.
Hoping for a 15 mini 🤞
Really pleased with the size of my 12 mini and gutted that the Mini line is over after the 13 mini.
A 15 mini with superior battery life would be great, even if it did thicken up to house a larger battery.
Man, that would be the dream. USB-C on a mini would be amazing.
The pipe dream is 120hz, but I get why the footprint would have issues battery-wise
i just want a new mini otherwise my 13 mini has to stay alive for quite a few years... I just hate big phones!
I want a Mini with a zoom lens, or at least a 48MP sensor for 2X.
It's lame they made a zoom a "Pro" feature after the XS.
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.
I like how solid recent iPhones feel but I'm finding the weight of the 14 Pro is actually hurting my hand. It sounds funny but it almost feels like gravity is stronger under it lol

I still have my 6s that I sometimes use to play music from (headphone jack; what a concept!), and it’s crazy to me how much lighter it is than my 12Pro. The 6s feels like it’s floating on air.
I think that would be a regression. When I first held an iPhone 14 Pro, I was like "Wow, this is hefty, but I really like it!" and right now I daily drive a Galaxy S20FE, which is glass back and metal sides. My phone feels like cheap garbage compared to a 14 Pro.
And the S20FE was basically a mid-cycle refresh of the S20 before the S21 came out.
Isn’t the FE’s back plastic?
It... Might be? I can't honestly tell. It feels like Glass, but... My wife's has this weird peeling thing going on.
I checked, it’s plastic.
I wish sites would stop using nm. The new chip should should be on tsmc 3n, that is a 5nm process. The old one was on 5n and that is a high density 6-7nm process
I thought I had read, several years ago, that Apple dumps a bunch of money into R&D of new tech in exchange for exclusive use of that tech for a period of time after it hits the market (e.g. ultra high-res displays on the iPhone 4). Seems like they haven’t done that as much in recent years but I’ve been patiently waiting for graphene batteries. Maybe this is the year 🤞
Do you reckon they will have solved the problem of the charger only working with apple devices for this version? They been working on that for about twenty years now. Lately I hear they have got the support of some imfluencial players like the EU government who are streamlining the process of being able to charge with standard electricity instead of special apple electricity. It's like regular electricity but smells of apples and not farts like all the android plebs contend with.
Nice

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.
