Debate: What's the single most useful feature of a smartphone?

Other than the phone, I would say the camera

PHONE OR FLASHLIGHT?

GOOGLE!!!

Battery life!

I take it you mean, the phone part?

No, I mean the entire smartphone & all of its capabilities.

Despite all of the glamorous and fun features the most important feature of a modern phone is, and always will be, Texting. It is how the vast majority of direct personal communication happens in modernity. It's not glamorous, but it is insanely important.

1. Battery life- ergo replaceable battery + extended battery + 150w charging are mandatory.

2. Screen size- ergo a trifold tablet that folds into a phone, with "each" screen being a 7 incher is mandatory.

For hard working, affluent alpha males, that is. Not for beta simps that will complain "my hands (and who knows what else) aren't big enough, plus I like to swim with it while slurping down penis coladas at the poolside bar".

listening to podcasts all day

Absolutely! The convenience of having the world's knowledge at our fingertips is one of the most transformative aspects of modern smartphones.
