Drawback: battery backup not cool enough But I still suggest Redmi 1s. With insane configuration (4.7 inches screen, 1.6ghz quad core processor, rear 8mp, front 1.6mp with hdr and full 1080HD, RAM 1gb, 2000mah battery) at a cost of 5999. I suggest u to buy MI power bank 10400mah for mobile battery management. It could refill ur redmi 1s battery 5 times at a price of 999 at Flipkart.com . I could send u 1 if u r unable to buy it from flipkart for an extra charge
