Redmi note 4 is the best phone according to me due to following reasons.The battery capacity has been upgraded to 4100mAh in comparison to the Note 3’s 4000mAh. I found I could get two days of use from the Redmi Note 4.The Redmi Note 4 is the latest mid-range phablet from Xiaomi, and it certainly looks like a fantastic upgrade over the Note 3. The new layout above the screen and 2.5D curved glass make it so much easier on the eye. The earpiece, front camera and proximity sensor are now symmetrical. I love this phone so much it is my favourite phone.
