I have my Thinkpad laptop configured to charge up to 80% cause I mostly use it on AC. On the occasional use where I am taking it off AC, is there a command that basically tells tlp to charge the battery to 100% and once 100% is reached, return charging behavior to the 80% configuration?

I see there is command sudo tlp fullcharge [ BAT0 | BAT1 ], but this command requires a reboot before the "80%" configuration is restored. Is there a command to restore the "80%" configuration without having to reboot?

Of course. It's

tlp setcharge

For convenience you may also configure

RESTORE_THRESHOLDS_ON_BAT=1

Then the thresholds will be re-applied automatically when you disconnect the charger.

    To be clear tlp fullcharge even says that you can use tlp setcharge without further arguments for resetting to your configured values – lucidbrot Feb 07 '22 at 10:04

    Yet, as OP said, setting charge criteria requires reboot by default. linrunner explains that one may use RESTORE_THRESHOLD_ON_BAT=1 to be able to, instead, unplug and plug power to apply the set charge. – Johan Jan 16 '24 at 09:51
