After updating my Z10 to 10.2 a week ago, my battery life is miserable and the loading of apps take twice as long as before. Very disappointing to say the least. If there is no fix for these issues I will switch in a second to an Android and would say "Bye" to Blackberry forever.

I would reach out to them directly at General Support Forums - BlackBerry Support Community Forums
