battery help

[Lcousin885]

I've had my phone unplugged for about an hour ish and it's already on 75% please explain what is draining so fast?

How old is the phone, and is that the original battery?

On a related note, do you routinely charge to 100%/overnight, or drain below 30%?

The numbers in your screenshot look good for app usage, so I don't think apps are an issue. I'm leaning towards the battery is just wearing out.
