Arkchun:
I'm thinking of getting the s20 but i don't know whether i want the cheaper version or the s20+.
Depends on whether you want to pay the extra $400 for the slightly bigger screen, depth sensor, 500mah battery, and most importantly, 5g modem. S20 will be 4g only here.
I will be interested to what the battery life reviews are like with the external modem arrangement.
