I don't see much of a difference, I have a 5c so I didn't get ApplePay. Haven't noticed if the battery life has improved or declined yet, but I'll keep an eye on it.
Battery life on 8.1 hasn't been as good as 8.0.2 for my 5s. I'm in the process of draining the battery to 0% and then a full charge to see if that will increase battery life.

Yup. You always need to calibrate when you're having battery problems.
I know Apple recommends going to 0% and then recharging. I just don't think it's the best way. I like to drop it to 10 to 15%, plug it in and then turn it off and let it fully charge. I do this at least once a month. I've been using this procedure for years and it works on all lithium ion batteries including my Apple products.
