If you want a smartphone that gives you highest value for money then without a doubt go for this phone.
Redmi Note 3 is the best phone in the market if you are having a 10k-12k budget.
It comes with outstanding hardware like a superior quality capacitive fingerprint sensor, an IR Blaster(infrared blaster), 5.5" 1080p IPS Display.
It runs on an Adreno 510 GPU and it has a Qualcomm SnapDragon 650 chipset which is powered by a Quad-core 1.4 GHz Cortex-A53 & Dual-core 1.8 GHz Cortex-A72 CPU which is excellent for gaming purposes.
It has a 16 MP rear facing and 5 MP front facing camera which does a quite fair job. Also it can shoot 1080p videos.
It has all basic sensors like gyro-sensor, proximity sensor, magnetometer, accelerometer, and auto brightness sensor.
With its huge battery that is 4050 mAh.it beccomes the best phone with a battery backup of 2 days. Ans I recommend that any user should buy it.
