After updating to patch 6.0.2 on my iPhone 5, I get this list of problem

Wifi speed is so slow

Sometimes I have to connect twice to successfully join a wifi network

Updating the apps on my iTunes in my computer is 5 times faster than updating it on the iPhone using the same Wifi connectivity

100% battery life was drained to 40% in just one hour because the location has poor signal but this isn't an excuse where my Samsung Galaxy 3 just drained by 10%
