I have an Aspire E 15 E5-575G-57D4 laptop and it's had battery issues for quite some time now. Months ago I noticed that it would shut off at high percentages and would continue to shut off at even higher percentages as time went on. As of recent it'll now completely shut off if I disconnect the charger. Here is the most recent battery report:

I've heard a few times that one of the selling points of this model of laptop is its excellent battery and I kinda feel that it hasn't lived up to that praise in the time that I've had it. I would like to know if there is anything I can do to remedy these issues or if I should just buy a new battery. Thank you for your time and your help!
