Hello all, I was bought karbonn k5000 mobile at 1399 rs from amazon website but in very few days battery of mobile is not working well and very few hours get low, if I use mobile or not use. Even on standby mode it is get discharge very quickly. In otger hand incoming and outgoing call from this mobile is very low, I never does messaging from this mobile then & then its bettery discharge quickly.sound quality is also bad, it is not value for money, design of phone is not good. This mobile doesn’t come with warranty so it is totally waste of money . Don’t go for it
