I had ordered for a new battery for lenovo A6000 through an authorised service center at Jamshedpur..it's been 2 weeks but the parts are not available in any of the outlets. There is no way that I can get a new battery now. The service center employees say since my phone is out of warranty, the company is not bothered at all and it may even take a month for the new battery to be available. I am completely stuck after buying a useless lenovo product.
