I was brought this phone from Flipkart in December 2015 .its now more than 8 month over phone is working perfect.battery backup is stunning .
You can use for approximately 1.5 day easily without charge. And charging speed is also good with 2a charger its full charged within 2hr .there are some problems I m facing that its processor speed not so fast .after that every things is good.
Thank you.
