Since 1 year I am using this redmi 3s prime., The performance of this phone is awesome. In new I faced some heating issue but now it solved with updates of mi. The camera of this phone is too good. I often use this phone for gaming. And the gaming performance is exilent. Charge back up of this phone. With 4g network on and online gaming of 10 hour .it works 24 hour in random use of internet and gaming. If no internet used it go for 4 days approx with average gaming. Over all this is the best phone ay 9k.
