I am using Moto G2 phone for the last one year.It has no issues upto now.Following are the performances based on
Camera- Its nice in outdoors but in low light I prefer adding extra app like camera 360
Battery- It depends on the usage, my phone is always connected to wifi so its battery lasts till 12-13 hours, on cellular netwrk it goes to 20 hours.
Speed- Fast if do Not install more apps.
