I own a coolpad note 3 and my brother recently bought coolpad note 3 lite.well on first use you will not see any difference in performance.
The basic everyday tasks perform same as the note 3.The camera on coolpad note 3 lite is the same as that on the coolpad note 3 and so is its camera performance.The pictures taken are great and also have lot of details.Battery life is a lot longer on the coolpad note 3 lite as compared to its predecessor coolpad note 3
