It's was about time we moved on to the next energy-storage technology for mobile devices. I can't believe in 2018, battery is still the main issue of all flagships.
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.
