Windows 10: Battery on laptop go low very quickly

Hi there, I have a Fujitsu Lifebook s792 laptop for about a year now. Since recently I started to get notifications how my battery is critically low and the windows have to shut down even when my battery is over 50% filled or even more. I checked all at the settings about hibernations and going to sleep mode and everything is perfectly fine. But I don't know why is this problem constantly occurs. Will I have to replace my battery with a new one or is there perhaps a possible solution for this. Thank you in advance.
