Latitude 10 - updated to win10 now massive battery drain

We use Dell tablets at work, despite me telling them not to, someone has updated theirs to Win 10 and is now complaining the battery only lasts a couple of hours instead of all day. Any idea where to start looking please?

Interesting. I'm taking the "no news is good news" option as he's not resplying to my queries on how it's behaving!

Day off today and am updating the wife's laptop to 10 so will so how that behaves
