iOS 10 and iPhone 6/6+: yes or no?

[Bill Av]

Sorry if this has been asked already, but searching gave me no hits. It has been my experience that upgrading an iPhone beyone one major revision isn't wise. Usually battery life takes a major hit or performance takes a dive. Are there any feelings on this yet? Does iOS 10 turn the 6+ into a battery draining slug?

Yes iOS10 beta 1 is draining battery on my iPad Pro 12.9 and iP6+
But this is normal in a beta with debug symbols enabled.

I'm losing maybe one hour of battery life on my iPhone 6 - nothing to be alarmed about

It was killing my battery until I realized that Facebook isn't compatible with it and was hogging my battery in the background. Sometimes like 60-70%. Had to uninstall. I reinstalled it again and haven't had the issue again but I turned off background app refresh for Facebook.
