Takes ages to start up since upgrading

[Jim B]

I turn my phone off every night before i go to bed and I'm noticing my iPhone 4 takes much longer to start up when turned on since upgrading to iOS 6.

My other half has noticed this too with her iPhone 4S.

Has anybody else noticed this?

How long does it take to boot?

I have an iPad 3 on 6.0 and it takes 25 seconds to boot, but it has a faster processor than the 4 and 4S.
