Hi I have bought several 9300 Curve 3G with OS 6.0 and have the same issue with all of them: the battery gets discharged after 5 - 7 hours. I have switched off all services, no SIM card is in, I just charge the battery to 100% and look for its status after a few hours and see how it gets discharged till the phone is dead. So, no 3G (nor 2G), no WiFi, no Bluetooth, no apps are active. I do not use the phone at all (no SIM card). I repeated the procedure with 6 different BB (same model) and the issue is the same. I have to deliver the devices to the employees but i can´t with this issue. I have for now stopped the purchasing of new BB's.

Any help is appreciated, thank you.

Sounds like a bad battery. Lithium batteries do not like to get discharged below 20% more than a few times.

Try a new OEM battery, not a cheap eBay knock off.

Also read through this section as there have been some reports of the later versions of OS 6 causing batteries to drain faster than before.

I have been using the original Lithium batteries. I have also been searching and reading most of the items posted but did not find any that have helped me further. Anyway I appreciate your comment and will be looking for more reported items.
Thank you
