I have bought this phone on 27th February 2017. The major issue which I'm facing is battery service . Once I charged this phone 100% at 11 pm and at 5 am I saw that, phone had only 3% charge left though I did not use my phone with in that interval . It is only one month old phone and I had to visit service center twice for this issue. After that also problem remain unsolved. Phone is heating very badly, as a result battery service is very poor. I'm adding photos of RETAIL INVOICE of service center. Please help me .
