I just can't believe I had none of these issues with Beta 1, but everything went to hell with beta 2. Springboard crashes, CPU usage, battery life, accessory bug. Thats not even half of it. Not one of these issues occurred on beta 1 for me.
I’m thinking of downgrading to beta 1. A pain but looks like have to downgrade to 10.3.3 then upgrade to iOS 11 beta 1
