Good afternoon, I hope you can help me. I bought a MacBook Air M1 in September 2025 with the battery at 93%. I only used it from time to time, and the battery percentage stayed the same until about a week ago, when it dropped to 91%, and then four days later it dropped again to 89%. Is that normal? I feel like it has very few charge cycles. I’m not sure if it could be because of the hot spring weather, since I try not to charge it in hot places, or if it started happening after I enabled the 80% charging limit with the new Tahoe update.
