Charged the case when buying in the 20th of December. At my rate of use (1-2-3 hours a day), the headphones themselves could not fit less than 60%. The case has three indications. Flashing blue - the charge is more than 80%, flashing red - less than 20%, red and blue - from 20 to 80%. Iβm now blinking blue + red, so it turns out that one charge of the case is enough on average for more than a month and a half! . . After the second charge, I decided to go all the way. Headphones ran out of power after 2 months (end of January - end of March)
