Hi, 
Same here , no problem with Sim or SD memory card , only battery, battery charging time increase dramatically, using original charger fast one, b4 it was charging in few hours from 20% to 100% now its charging around 5-6hours. 
Good think my reception increased, so now I have HD calls , and WiFi calls thats very good. 
Waiting for changelog . 
Thanks to bv team.
