Right. And if they don’t do that, then the phone will just get thinner. We already have incredible energy density compared to a decade ago, but that budget is used up by shaving millimeters off the thickness.
I wish they didn't do that, I would gladly carry around a slightly bigger phone if it had much better battery life.
I get why some people prefer thinness over battery life. Not all use cases are the same. Just wish that there was an option when choosing a model to go with svelte or chunky.
