I am fan of redmi series by xiaomi. I bought note 5 for my mom. A 5.5 inch smartphone. Its speed is good thanks to 3gb ram. Memory is 64 gb which is a quite good enough to store many apps and games. Camera quality is better in this series. Better than note 4. I also have note 4 in my collection.
Battery is very good. Once get fully charged, it can easily last for aday. Qhether you surf or play game the performance will never let you down. Lastly but not the least the price. The price is quite affordable. I bought it from filpkart in offer 9999. THere was also a bank offer was going on, which gave me 10% discount.
Overall an excellent phone and my mom is quite happy with it.
