I notice after the update the phone is quite battery draining and sometimes when I am connected to wifi but there isn't any icon of wifi instead it still stick at 3g.

I found an issue with blue tooth and my car. I can get it to recognize but once I turn if car and turn back on,my phone is not getting picked up. I have to delete the car icon and repair. Each time I enter the car

A lot of people posted that Z10 drains battery so much after update.

In my case too.

Go to settings -> privacy -> diagnostic -> turn that inside OFF (can't remember exact option).
This will help you a little bit but nothing big or special.

Blackberry definitley have to relase fix for this issue.
