Xiaomi Redmi 1s is the good mobile economically. I bought this mobile for six thousand.It is the first series from Redmi. Its battery backup is good. Its battery get fully charged in approx 4-5 hours. The processing speed is also good. It gets little bit heat when I use this continously 3-4 hours but there is no problem in my mobilet till now.it has dashing look. It has 1GB ram and 8GB internal memory and 1.6 GHz quad core CPU which makes it fast. Its camera is also very good, with 8 mega pixels rear and 2 mp front camera. I suggest you all that it is very good phone.
