FJTG10 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)Anonymous10 years ago • purchased this product+220purchased this product 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.
