Xiaomi redmi note 3 is good mobile in this budget segment. The company offers 2 variants i.e. 2 gb ram with 16 gb internal storage model at a price of 9999 and 3 gb ram with 32 gb of internal storage at 11999. I would recommend to buy the second one. This is the only difference between these 2 models rest is same. The processor is very good in this device and also its major plus poont is its battery which is 4050 mAh which is enough in my opinion. However it has some negative things also that however it has 16 mp camera but it is not that great also sometimes phone heat a lot also phone is designed in such a way that it feels slippery.
However in my opinion the phone is good in this budget and if your budget is under 15000 than you must go with this.
