Testing a hypothesis today.
Had been running both Windows Hello and Hey Cortana.
Turned off both, lets see how much battery life improves. My theory is it will improve significantly since both of these services run all the time even when the phone is not in use.
Ok so things were MUCH improved yesterday and my test worked wonderfully.
I only turned off Windows Hello and Hey Cortana, did not make any other changes so all other background operations, updates, photo sync, etc were operating as normal.
I took my phone off the charger at 7:30AM and 16.5 hours later at midnight when I put it on the charger it had 27% of the battery left.
During the day I actually used the phone quite a bit. I read a lot of news articles on it, posted a lot of things on facebook, watched a car video review for about 25 minutes, and used it in the mall for price and product lookups (inside the mall it was on 4g and not LTE).
So, for my phone, I have gotten the battery life to where I want it to be. A full days use without worry of the battery going critical. In fact I'd say at 16.5 hours that is more than a normal full days use cycle. Right now I am in east Texas where ATT and its LTE coverage are not the best so I am hoping once I get back home (DFW) where ATT coverage is spotless battery life will get even better.
What my next test will be is to go one day each with just WIndows Hello and then just Hey Cortana on to see which one is the bigger battery drain.
My guess is that Hey Cortana is the biggest culprit since it is processing every single sound it hears.
So everyone that is having terrible battery life turn WIndows Hello off and Hey Cortana, things improved a lot for me when I did.
