need a phablet replacement for my S4

[ttrance]

hey guys...

before I make any purchases, the first question is... is it worth it to sell my Galaxy s4 i337 to upgrade to a phablet?

I use my phone to study and it requires a split screen of two texts. So I need a lot of space to be able to look at the left side for the original text, and the right side for the commentary of the text....

With that being my only major concern, I'm thinking of selling my S4 here, and using the money + a bit extra to buy a really good phablet so I can study on the bus daily with less difficulty..

So if it does make sense... Which phone to buy?

I really like the new Nexus 6, with dual speakers, QHD... but 700? Are you kidding me?

So looking at a phablet of some sort... I'd like to spend less then $300. I only play 1 game, Clash of Clans, and on the rare occasion I watch something on it. As I mentioned before, mainly I'm reading text, studying, and using it for work related stuff. So prime screen real estate is key. ALSO BATTERY LIFE!! I am sick and tired of having to take a charger everywhere with me.

In fact for my Galaxy s4 I was thinking of buying one of those zerolemon 8500mah battery extenders+case...

So to sum up:
-Big screen 6'+
-Dual speakers
-Massive battery
-Powerful enough for basic stuff, clash of clans...
-Ideally less then $300.

Thanks guys!

A year ago or so I was very active in whats going on with china phones, but not so much anymore...

BTW one of the factories in China mentioned this phone to me... A 1:1 note 4 clone... http://v.youku.com/v_show/id_XODEyNTgyNT...pcqq.group

Waste of time?
