My Lenovo Ideapad's battery is bad?

My Lenovo laptop was only just unplugged a couple minutes back… It's already at 93% and is expected to last another 3 hours and 20 minutes.

It's originally supposed to have a battery life of between 5-6 hours… Anything I can do to help get it back to normal?

Battery life does decline with use. Going to power setting and choose Eco mode will extend the the time, but it is a bit like running your car on half throttle all the time. I would accept it and get a new battery when you find it unacceptable
