I'm on an iPhone 5 running 8.0.2 and I'm not having any issues except below average battery life. So I go to the usage and it says Safari is taking around 26% over the last few days, today included. Meanwhile, other apps I am using are running around 3-6% which I'm perfectly ok with. The thing is I am hardly using safari, I'm wondering if there is some background process Safari uses that's draining it so fast.
