BBM Enterprise and BB10 resource usage issue

[aiharkness]

I would be interested in knowing if....

Someone made the switch from BBM Protected to BBM Enterprise last week on BB10

and

Began experiencing very high battery drain and CPU usage by System and BBM Enterprise

and most importantly has found a solution and will share

My first guess would be to turn off device/SD card encryption.

Thanks. I did that. And it seemed to fix the problem, but then resource use returned to high levels again. What seems to happen is resource use will return to normal ranges after restarting the device and stay down until BBM is used again. I've noticed some messages sent or received don't immediately cause resource use to rise, but definitely resource use will stay low after a restart if no messages are sent or received with BBM. This happens with and without encryption.

I did get a request from BlackBerry to submit logs and I did that yesterday.

I deactivated BBM Enterprise on wife's Passport. That returned her to BBM with Protected Plus. Solved battery drain problem, but of course she loses cross-platform video chat. Seems to be the only workaround for now.

I'm going to manage until there's a fix from BlackBerry, or until before my next trip, whichever comes first.

BlackBerry pushed an update sometime Friday my local time. Someone I'm in contact with updated before me and reports the battery drain issues seems to be resolved.
