Macbook Air Cycle-related Questions?

If you mean the battery is not draining below 80% while the power adapter is connected, then this is correct behavior since this is how macOS exercises the battery & prevents the battery from being at 100% all the time. If the battery is always at 100% charge, then it will tend to cause the battery health to deteriorate faster.

Unfortunately I cannot find the Apple article which explains Optimized Charging since I think Apple may have changed the articles around removing the more detailed explanation.

"Macbook Air Cycle-related Questions?: So i turned on battery optimization and my macbook starts to charge & uncharge and specific times, not letting the battery drop below 80. However, this happens about 3 times, maybe 4 or 5 a day, and I'm concerned for its cycle count. Will it increase if this happens frequently? I just have it charged in the entire time."
