Battery Drain after Windows 10 Anniversary update (Mobile)

[Windows Central Question]

Lumia 735 on Verizon. Updated to 1607 OS build 10.0.1.14939.67 a couple days ago.

Huge change in battery life...for the worse.

I check battery usage by app...and its all Cortana. For example, I fully charged the unit, unplugged it and, it sat untouched for 10 hours. Cortana ate 50%!

I don't use Cortana normally. I've turned everything off in her notebook. Is there some way to turn her off...or save my battery power?

Let me be clear...this is not cool. I don't care what bells an whistles MS wants to brag about adding (mostly spyware by another name assuredly)...I used to be able to go days without recharging...now I can't go a day without the phone going into saving mode.

I am not happy about this.

Thanks for any advise.

disable it from running in the background and unpin it from start screen
Then try a soft reset
