Good day all The watch is now 10 months old, there are days when the battery needs to be charged 2 times and there are days when it needs to be charged only 1 time. only 1 time, I have a second watch with a diameter of 44mm that seems to have a bigger battery. I take it when I go biking or hiking, then I have to charge the battery after about 2 days. Does anyone know the problem? The Watch is set to: No NFC No GPS Bluetooth Yes Screen always on. Thank you for your answers Otherwise I am completely satisfied with the watchen. Greetings Twithy
