I am trying out Monterey on my early 2015 11-inch MacBook Air (i7 2,2GHz, 8GB) and am curious how other of the earliest supported MacBook models do in terms of battery on this OS?
I’ve been running it for months on my 2015 11” Air (i5, 4GB, 128GB) and I haven’t noticed any degradation in the battery life compared to any other versions.
I have both the 2012 and 2015 versions of the 13-inch Air and battery life is great. Battery life will deteriorate over timed but you can swap out the batteries for about $50 each. Try to never charge past 80% and that will double the life of the battery.
