Sir,
I purchased a lenovo vibe b handset on 11.05.2017. That day i fully charged the handset battery. Since 7-8 hours as instructions. I did not work with the handset that night. But next day morning i saw the battery level went down to 80%. Also when i used some application like whats app, facebook, twitter, instagram etc. When i used these apps, the battery level went down very soon. Example before using whats app battery level 80%. After that the battery level 65%. Just 10 -13 minutes use. When i brought the handset to authorised service centre (Hcl services ltd lenovo exclusive kolkata), at first they told me that there were some issues in the handset, you must subit the handset. That was friday (19.05.2017). On monday they called me to delivery the handset. When i take the handset and asked them what was the problem? They told me that there was software problem which was resolved. After that i took the handset and returned home. After some time the same problem was happening. Today when i took the handset to service centre they told me more two indiscretion problem. They told me that the battery backup is no longer because the reliance jio sim network fluctuate which was seen on display. After that they again said to me that the 1% battery level will goes down after 3-4 minutes.
Now which comment i will take?
1. Software problem.
2. Reliance jio sim network fluctuate which is seen on handset display.
3. 1% battery level will goes down after 3-4 minutes.
Sir, i want your interference about this matter as soon as possible. Otherwise i will complain to state consumer forum.

Thank you and regards,
