I purchased redmi note 4 ( 4 GB 64 GB) one month ago on price RS. 13000/- and would like to share my experience about this product. This is one of the best product ever by redmi. Sound quality, visual quality, features of this product, official updates everything is awesome.
I can able to play heavy graphical games without any halt due to its 4 GB of memory. Given 64 GB internal memory is just so good to store movies ans data and one should definately buy this product just because of it batteey quality. Redmi note came with 4000 MAh which gives almost 2 days of battery backup.
I am completely satisfied with product.One thing I would say is the camera quality is not so good but we cant expect any thing more then this in this budget.
