I upgraded my Torch (9800) a week ago, and have been noticiing battery drain issues. The problem is NOT persistent, but is happening most of the times though. I am currently on OS v6.0 bundle 3049 (v18.104.22.1686, platforn 22.214.171.124). My Wifi and Bluetooth are always OFF. Only using the Bell network, for which I have all the 5 bars available.

I have investigated further, and I found that the Blackberry System Software was the one running with the highest CPU - usually in the high 70s, to even high 90s. And this was consistent over hours, until the battery was dead. I have since removed any apps I suspecpected - such as Nice Office and LinkedIn. But the problem still persists.
Battery pull has been done multiple times, as well as I have checked, and there are are no OS updates available.
Now, currently, only the basic apps are loaded (Alt-Back) : Home, Messages, BBM, Phone, Borwser. All other apps are closed or exited.
Investigating further into the modules within the BB System Software, I have found that the net_rim_io_impl, is the one consuming ALL of the CPU. I am not sure where/what this module does - so I am unclear on what service within the BB I can turn OFF to get rid of the issue.the CPU for the System drops a bit, as Options uses up some, else, it goes back to 90s, if left alone with either a fix to the module, or else, via some workaround, wherein some service can be stopped or some setting can be changed to avoid this battery drain.
