I've used Samsung Galaxy S7 and currently have S8 (both are similar). I've had no issues browsing/streaming or fitting it in my pocket. (with or without keys)
Battery isn't fantastic but hard to compare without having anything else apart from Samsung myself, the fast-charging however is very good for a fast charge... a I've had no issues with charging cables.
I dropped my S8 on it's back from desk height to floor (carpet) and it cracked a little of the back. I have since bought myself a phone case that goes around the phone, and it's what I'd advise with a phone that breaks as easy. (I can find one on Amazon if you like)
Not sure if it's what you want but cameras are superb as a side note.
I assume Black Friday will have a deal on for it somewhere, so yeah probably a good time to be looking... build up to Christmas sales as a fall back too.
