But then it has to be like 8" Sorry, this is of course my personal opinion, but I don’t understand how some 5.5" or 6" phone could replace a 10"-12" tablet
Not really. Power consumption has been reduced, yes. The CPU efficiency has improved. But battery tech itself, not at all… I mean they no longer require you to fully charge and fully discharge multiple times before first use, which is a good thing, but that’s not really the battery itself.
