Micromax canvas Mega 2 Q4 Hd has a main problem in their battery and rech temperature more than 45°.I used this phone for 3 months but I faced many problems in this phone. You can not use this phone for more than 3 Hours. Because the phone temperature reach to 45°. This is very dangerous temperature for a plastic body mobile. For A metal body phone, this is okay but for not for a plastic body phone. Also when you can charge your phone, same things happened as same as before. The temperature reach to very high. I think processor of the phone is not good, why this phone has too much heating issues. Also the battery back up not good in this phone. You need to charge this phone more than 2 times. Thank You
