Coolpad India — coolpad 3s mobile battery

I ordered a coolpad note 3s mobile on jan 21st and received the product on jan 23rd. The package did not contain a warranty card.

Order number : [protected] dated 21/1/2017.

Now the battery is draining fast and dead in 2-3 hours after a full charge. I tried removing all unwanted apps and even a factory reset. Nothing works and the battery is still draining fast.

As it is a sealed unit i cannot buy another battery and replace, which would have been a fast fix.

I would like to have the unit repaired or replaced under the applicable warranty.
