Hi guys,
did anybody of you also experience that the Macbook turns off, although it shows about 20% battery remaining? When I plug it in after that and it reboots it shows about 10% battery.

My battery stats say:

• 44 cycles (I have the macbook plugged in all day while working with it about 8h per day and al dente set to 60%)
• battery health: normal
• max. capacity: 100%

Am I using Al Dente wrong? Or is this not because I use Al Dente the way I do?

Thanks for your help!

Do a full recalibration of your battery, as described here: https://apphousekitchen.com/feature-explanation-calibration-mode-2/
