Battery Problem

[albertomm1]

I have a battery issue with my Xperia M. After a complete charge or more than 4 hours, it only last 13 hours, and what is worst, the screen was only activated for 12 minutes!!!

I've already sent the device 5 times to the technical service, and they only replace the battery, or so the say.

Any help?

The only advice I can offer is that you need to either return your device to the place of purchase or contact Xperia care and request that a more in depth test be carried out http://www.sonymobile.com/global-en/support/contact-us/

Thanks Thommo, but I can't cause it was purchased second hand. It is still under warranty but I keep sending it to the SAT and they give it back with a battery change. It has been sent 5 times already...
