Jailbreaking iPhone 6s
So I have jail broken before but it was a while back and it really slowed my phone down (back at iOS 6/7 seven mainly), and I was wondering if it is any better now. I have an iPhone 6s 64gb now and I am currently running the developers build of iOS 10 however I am planning on reverting to iOS 9 to jailbreak. So all I really want to ask is A) Is it faster B) Is it reliable for an extreamly active user. (I need to be able to have my phone on me 24/7 exc charging but I mainly use power banks) Any help will be appreciated.
