Hi friends, I am akash just bought it 5 month ago. Fully charged phone is discharging without any use within 30 minutes. Took it to Lenovo service center 3 weeks ago. Still no response from them. Giving some lame excuses. Finally now they said it is mother bord problem and will take another 3 weeks. Very bad phone no dual sim stand by recharge longer time any comlaint and little heating issues
