Xiomi recently launched redme note 4 or xiomi note 4 it comes with snapdragon 625 in india and mediatek decacore in china. its performance is little good than redme note3 and camera quality also good. its battery performance is excellent due to snapdragon 625 . this processor is very stable octacore processor. which may help in gaming performance.its build quality is very good and shiny.but it does not support fast charging which may irritate you while charging. if you have redme note 3 so you can not upgrade to note 4 due to alot of similarities and if you are new xiomi customer so you can buy it.
