Huawei honor 4x
Honestly I am using these phone for about 6 months I have no issue of heating while playing heavy games I have played many heavy games on this phone like asphalt 8 airborne, real racing 3, wwe2k, gta vice city, gta san andreas without lagging.
It has a 3000mah battery it comes with 1.2Ghz quad core processor, 2gb of ram ot runs 4.4.4 kitkat which is a liitle bad thing the battery back is good and last upto 1 day with moderate ussage it comes with 13 mega pixel of rear camera and 5 mega pixel of front camera it comes with 8gb of internal storage which is not good if u r a gamer it comes with screen resolution of 1280* 720 p hd display the picture quality is good enough
I loved the phone and I m thinking to sell this phone and again buy a honor 4x
