Why is my battery draining so fast?

[Windows Central Question]

I've updated my laptop with Windows 8.1 to Windows 10 TP. Update went fine except for the fact that my battery drains fast. A fully loaded battery last app. 30min. In WIn8.1 it was at least 3 hours. Is this a bug or is there sonething very wrong here...

because its not final code?

i know the first time 10 got a preview it cratered my already bad battery life. I'd chalk it up to it not being as efficient as it could be and perhaps not perfect driver workings.

Although 30 minutes sounds a bit too dramatic, maybe something is eating up resources in task manager?

I've checked already and I can't find anything. Memory is about 25% and cpu is not higher than 1-5 %.
