I'd have to say that based on my experience, the Note 8 is hard to recommend, compared to the Nexus 7 , iPad, and other tablets I've owned as a sort of tablet-o-holic. I get abysmal battery life - even turned off in my bag, mine runs down in under a day, and when used, the battery is awful. Others here report more success. For me, it's never got power when I need it, period.
Sounds like the new one is going to have a lot of improvements worth considering.
