A quick follow-up.
After ten days, I’m charging Mudita Harmony for the first time with 13%. I wrote before that I would expect around one month, but I was too optimistic. However, I don’t feel it is a bad thing. 10-12 days of battery for everyday use is ok for me.
I want to report a curious situation. When I adjusted the hours the first time, it was only a few seconds desynchronized from my mac. Ten days after, I see a plus three minutes difference. Is anyone experiencing the same thing?
