I was looking for a phone for my brother as his earlier phone was not working. As he has used other xiaomi phone before and he liked MIUI very so he told me to buy him a xioami phone so without thicking any further I told him about Redmi note 3 and we bought it.
It has been almost 5 months now and he does not have any problem with it yet.
The most liked feature that phone is its massive battery of 4000 mah. It gives backup of almost 2 days on moderate usage. The performance of it is also good according to its price range. After the updates the memory management has also improved.
If any one is looking to buy a phone under 15k then this is the best phone you will get in the market currently.
