Dear ASUSTek,

There are many users like myself who have upgraded their tablets (Fonepad ME175CG) to the latest OTA upgrade (v6.3.9) and suffered from battery drain problem as a result of that. There is a bug in the telephony service that is causing the battery to drain continuously. Please fix this asap so that my tablet is again usable.

This is a world-wide problem in all tablets of this model that are running the v6.3.9. Here are a few links from ASUS forum site that contains relevant posts by other users who are facing this issue:
