Even when I have no account. It's constantly downloading and uploading something.
This happens almost every day, at certain hours of the day.

You have no email, calendar or contacts being synced?

Nope. I just bought the Z30, and I intend to isolate the single account which cause the battery drain on my Z10, which usually is caused by the hyperactive PIM service. Then when the problem starts, I deleted my account, one by one. Until there is no account left. And here it is. Still draining. And the CPU usage of my PIM service is around 30-50%. Doesn't make sense. Something is wrong with the OS... I love BlackBerry 10. So much. That's why I'm buying the 30. But this issue needs to be addressed as soon as possible.

There are a few threads on this. It seems to happen periodically when you're in a low / no signal area. The best thing is to reset when it happens.
