My Galaxy 7 battery is lately running down much faster lately for some reason.

[Android Central Question]

I turn it off and charge overnight. Sometime even with near full charge, I can't open some emails and apps. By late afternoon it's almost drained, but previously it had 60% life left in the evening. I don't use it much and never stream anything. Mostly used for calls and checking email.

What do your battery usage stats indicate as using the charge after charging to 100% and using until at about 40%?
