Windows 10: Battery life draining faster than usual

I have been using my laptop alot for online school and playing lots of games, and recently I have noticed that its going down MUCH faster when I play games that it used to, so I found out how to get a battery report and I want to know if this is good for my computer, and what I should do to get the battery life up again. image below

Battery drains faster in Windows 10.

This is all just rubbish! I've tried all the suggestions to obtain better battery life. I now resort to just turning the device completely off, and it still drains. Microsoft just trying to make excuses for their inferior batteries in the Surface line.
It makes no sense that having a 100% fully charged tablet, then when shut down completely (not sleep mode) that the battery has drained down to 65% when you turn it on the next day. All this in SHUT Down Mode! Give me a break, that's BS!!!

 

Battery drain much faster

Having problems with my Lumia 640 DS . The battery drains much faster when using high speed networking like 3G services. It hardly sustains for a day. Previously I was on wifi usage and compared to that it drains out much faster. I used to get almost 2 days
of battery on wifi usage.

Help me out. What should I do.??
