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. |
It's so weird that we just come to expect to be screwed on these phones, when if it was anything else, especially the sort of devices that are more commercially focused than consumer, you'd demand better.
