This phone is a perfect mobile in low budget from xiaomi. It comes with 4100mah battery which will last till 2days once you fully charge it and if you do not use the internet connection otherwise it will last for 1day. I myself own this mobile. One day during my holidays I decided to check its battery and from morning 8a.m. with my battery having 98% charge I started playing games n watched movies n I was constatntly using the internet n I also turned my gps on and after all this thing at the end of the day at around 10.30p.m. I stopped using my mobile and I noticed that I was left with 20% of charge.
This battery capacity is the best reason to recommend redmi 3s to everyone.Not only battery it is of 5inch size which makes the mobile small and good in grip. It also has 3gb ram with a very good ram management which will never let your mobile hang. It has got metallic body and a amazing design. Its camera quality is also very good.This mobile is best to buy if dont have a huge budget.
