I bought my wife the M1 MBA and I wanted to know for her usage how long she could go between recharges. She went from Tuesday evening until Saturday morning before hitting 20% battery remaining. The is just an evening use computer but I still found this to be impressive. Much better battery life than my 2012 11” MBA, which required charging every evening due to the 9 year old battery only lasting a couple of hours per charge.That's awesome! I'll have to remind myself, where I put the power brick last time I used it.
