FJTG9 years ago+110The Logitech website states a battery life of three months. Is that in operating mode or when it's lying around switched off?Show in original language (German)Anonymous9 years ago+220 Helpful answerI no longer use the keyboard (Logitech K380 is better), but I remember that the charge was not even enough for 3 months when switched off. In use, it was only a few weeks.Show in original language (German)Comment
