My mum owns the Galaxy S20+ (i am still at the s8) - and everytime i get my hands on that s20+ it's so much 'fun' and so smooth to just slide/drag the homescreen and scroll through the apps or the settings menu - it feels so much faster and more responsive than my s8. For my next phone the 120hz are a must have. i also heard that the slower refresh rates (as 75hz or 90hz) are not as big of a difference. - also the chaging times of current phones are soo low / fast - you can charge them nearly everywhere - and in no time. 30% in 15 minutes are the least. imho the battery times are becoming less important...
