Besides high weight and less battery .
the phone has many disadvantages like less ram of 1 gb which gets filled up when we install 3-4 apps from google play store.
phone gets discharge very fast and takes several hours to recharge .
I really dont recommend this phone
the phone is obsolete in both design and features
phone is not reliable shows its true colors within 3 months of purchase
instead I recommend you to go for yureka which is also from micromax.
