Pros:
Quality of the material used
cheaper than other expensive plastic handsets
ease of use and multi tasking
internet usage and console level graphics performance
No much charge consumed only if internet in used(without internet gaming and maps location, facebook and other apps consume less charge).
cons:
drinks charge like anything on playing games
gets heated often( I use a armour guard so I dont feel the heat much)
storage size is less with 8.1( only 5.8gb is available for user)
gets slow with 8.3 ios( never hangs it just gets slow with usage and internet speed and others remain same)
