How can I know if my Xperia sp is refurbished?

[vierexavier]

Hi,I was looking on google a way to know if my phone is refurbished but I cant find anithing useless. So anybody can tell me if there is a way to know it?

I bouth my phone in a local store and the seller told me it was new and original but I notice that the battery drains too fast. And the box, the user guide and even in the back on my phone are on Chinesse.

I dont know if is a copy or if it refurbished.

Please any advice?

Best to check with Xperia care and ask if it's been registered before and get the IMEI number checked http://www.sonymobile.com/gb/support/contact-us/
