my favourite laptop has to be Panasonic's Let's Note I had one wayyy back model W2D and they eventually had this physical button that let you charge up to 80% for longevity reasons.
That being said, I still own a macbook pro from 2011 and it's battery is still 100% healthy so I'm quite surprised to see how much's changed...
I doubt you're really at 100%... if you go to "Apple menu > About This Mac > System Report > Power > Battery Information" you can look at "Health Information > Cycle Count" and see how many cycles you've been through... see "Cycle Count Limits" at https://support.apple.com/en-us/HT201585 for expected lifetime. You could also look at "Charge information > Full Charge Capacity (mAh)" and compare that to whatever the original capacity was for that model.
says 115 cycle... as it's plugged in most of it's life and full charge capacity is 6435mAh which sounds about 100% still.. oh and it's actually late 2012 rather than 2011 felt like I got an upgrade lol
