Is there a smartphone (any OS) that can hold 20+ (or at least more than 5) tabs in a web browser at the same time, so that you can switch between them instantly, land at the same position and without a tab having to be redrawn from cache (even when you come back after a long time or even just an hour)? I think I've read somewhere, that on Android this is not possible, but I was thinking that it might be with 3gb of Ram like in a Galaxy S6, but then my galaxy s4 (2gb of ram) utterly fails in that scenario and does even worse than my moto g 2014. Often when I want to understand a text about a topic I know nothing about I need this functionality to look up new terms/concepts (which in order to understand I need to look up even more stuff). Or when comparing listings for a used product or when looking for a new apartment etc. These constant little waiting times really interrupt my flow and force me to sit down at my PC to get stuff done. A phone isn't really 'smart' for me if it can't do that.
