After using multi window for sometimes, I'm thinking about let's go my SGSIII GT-I9300 and buy GT-I9305, getting 2GB RAM, I think 2GB can solve the lagging in multi window. Am I right?

true, if buy S3 LTE better wait for S4 because need with 2 month only. 

JKay mods have blue circularr battery icon. But you need to root your phone first.

Xda ko.

Or google jkay battery mod confirm ada. Lol

Your phone is LTE version..right..?
Look JKay mods meant fot GT-I9305 with the matching build number as your phone. Download the files then flash via CWM.
Btw..your phone must be deodex. I think JKay stopped modding for odex rom already.
Happy flashing..!!

Bwahaha..and i don't think your rom is deodex either.
Better read the xda link that i give you first..bro.
Wrong flashing can brick your shinny phone...lolz
