Panasonic eluga ray max is greater than the other two models eluga ray max32 gb and ray X but at one thing ray max is not great that is at its display size because its difference 5.5 and 5.2 inches.it is very fast because of its 4gb ram and its 430 snapdragon octa core processer.and its camera has to be good because it had 13 mega pixel of back and 8 mega pixel of front cam.And I was feel just good at this battery point . Its battery power is 3000 mah .if we seen in redmi note4 its batery piwer is more than 40000 mah.
