Why would a company choose to produce an inferior product?
My guess is there is a trade of that's worth it on the product side. That's why you can't buy a compelling phone w a replaceable battery anywhere. Its an incredibly competitive market. If there was a design that worked and tradeoffs made sense it works certainly exist and do well since who wouldn't like it.
I just believe that the fact it doesn't exist tells you that the trade offs aren't worth it. I didn't buy conspiracy theories how dozens of independent manufacturer and hundreds of hardware manufacturers that are on the side line so collude to keep this design choice at bay.
Most phones quietly lose their ip68 when battery or screen is replaced
At least with phone batteries, to make them removable, means removing some capacity. Lots of phones squeeze as much cell into every nook and cranny as they can
> Why would a company choose to produce an inferior product?
It costs less to make the inferior product, so even if you have to lower prices, you make it up in volume.
There is another option here - the company may refuse to offer a replaceable battery because it would eat into the market itself by increasing the lifetime of the products. And different companies may have agreed, in secret or just tacitly, to perpetuate this. Especially as replaceable batteries are not THAT high on the list of features consumers actually look for - it's not like Samsung could eat Apple's lunch by including a releasable battery in their next flagship. So, better for everyone if they just don't include one.
