Should I use savings to pay off mortgage now?

I have enough savings to pay off my mortgage but I've been holding back on doing it because I'm earning more interest on my savings than I'm paying on my mortgage.

Should I now use my savings to pay off my mortgage, whilst I still have savings? Would this be a sensible thing to do?

Advice please as Im worried about the current situation.

Thanks,
