Barely half a year has passed since Sony announced the Xperia E3 at IFA 2014. Now it is augmenting its budget smartphone line with the new Xperia E4. Like its predecessor, it promises to give as much of the Sony Xperia experience that it can at price point. This includes a 2,300 mAh battery promised to last 2 days, the distinct Xperia design, as well as customization options. One rather peculiar thing about the Xperia E4 is that Sony has opted to go with a MediaTek CPU this time around.
