I have been using Redmi Note 3 for the past 2 weeks, its performance is not even comparable with other high end devices like samsung galaxy s7 and pricing is the best part for 11500 I got a phone with 3 gb ram, 1.7 octa core processor, 32 gb internal memory, full metal body, very fast fingerprint sensor, 16 mp back and 5 mp front camera, NFC, fast wifi(ac band) which all are seen only on flagship smart phones of other company, its design is very sleek, slim, round edges makes easy to hold.it doesn’t feel like using a 5.5 inch screen phone body size is very much minimised.
There is not much heating issue I have tried alot of games like asphalt at full hd resolution and there were no lags or framedrops with an average gaming, full day wifi, screen brightness at optimum the phone battery last more than a day. under heavy usage battery can also last for a day or 24 hrs
