Upgraded Air M1 (2020) to Sonoma. After installing it on top of the previous system did a full erase / "clean install". Before Sonoma, battery health had dropped to 81% and had remained there for at least 6 months. Now, at least according to Coconut Battery, health jumped to 88%. Wondering if this is unusual or if Coconut Battery is even accurate.
