I had one of these phones that would crash under load and the update fixed it. The technical fix was sound. Batteries can't supply full power as they age, and the CPU needs high power when it runs faster. It's an annoying reality of battery powered devices that looks like a conspiracy to boost sales.

Imagine a world with replaceable batteries.

Should be coming back in 2027, when the EUs battery regulation goes into effect. While it doesn't iirc require easily swappable batteries (like the Nokia of the olden days, where you just took off the back cover and put a new one in), it's specifically designed to put a stop to the current amount of device waste coming from poor quality batteries.

Imagine the tradeoffs, though.

A "user-serviceable battery," by requirements, is going to be a hard shell plastic sort of thing - which means a decent fraction of the "total battery space" is a protective layer, not active cell components - so some significantly reduced capacity compared to having a "non-replaceable" battery ("slightly more difficult to replace"). You also end up having to devote space to whatever mechanisms keep the rear shell in place, and may have a harder time waterproofing it as a result (which seems to be standard anymore - the number of people I see at the gym using their phones in the hot tub or sauna is boggling).

Batteries, under light use of phones not kept in pockets, last a very long time - 3-5 years isn't unreasonable, and many will last longer. Batteries, under heavy use of a phone kept in a pocket and run hard, will still typically last 1.5-2 years. So in exchange for "slightly more inconvenience less than annually," you get a good bit more capacity and runtime.

Apple, in general, hasn't made their batteries nonsensically hard to replace. They've used the "pull tab sticky" sort of thing for some while, which is far nicer than "glue the whole thing down," and their newer devices are using some sort of electrically released magic (apply 9V to the adhesive, battery pops out).

There's no such thing as a free lunch.

Now you're trading off water resistance, size, and capacity. Choose 2.

I’m assuming you meant “user replaceable”, because that’s really the key thing to understand here. Almost every phone had those, but most of them switched over half a decade. There was a long period where consumers had tons of options with removable batteries, and the market unequivocally rejected them. It’s always a mistake to assume that people drop hundreds of dollars on worse products based on nebulous claims about marketing, so clearly the average phone buyer thought that they were buying a better product. Why?

Removable batteries were useful in two situations: before a phone could last all day, swapping batteries was handy for people who spent a lot of time away from chargers … but most people don’t need that very often, if at all. The other situation is a few years in, when the battery life is starting to be noticeably worse. For that to be a big deal, it has to happen before you want to buy a new phone for other reasons. This is a valid complaint but you only experience it every few years and can fix it by spending the equivalent of a month of phone service and waiting roughly the amount of time it takes you to get lunch.

Now, what did we gain? Using a sealed battery made phones far more durable – people used to joke about dropping their phone and having the battery fly out! – and especially made it easier to make them dust and waterproof. It also made them cheaper, smaller, lighter, and sturdier.

So basically the average buyer gave up benefits they rarely used in exchange for things they noticed literally every time they picked up the phone. The day the iPhone came out, the entire market re-evaluated what they wanted in a phone and almost everyone decided that they didn’t make 18 hour flights with no charging often enough to give up that solid, luxury feel. Just as Google’s software developers made a crash project to copy the iOS UI, the hardware designers saw the lines around the block at Apple Stores and correctly concluded that nobody minded the drawbacks of a sealed battery.
