How exactly does optimized charging work? (alien.top)

I’ve had my watch a little over a month now, my first apple watch and been very happy. One thing I’m confused on is how the optimized battery charging works exactly?

My charging habbits are pretty much like this: in the morning when I shower & brush teeth I charge a little, afternoon when I finish my workout and shower I charge a little and evening before bed as I’m getting ready I charge a little. This way I keep the watch between 20-80% most of the time and it doesn’t take any effort for me.

However, if I forget myself or take longer to shower, the watch always blasts past 80 and charges to full immediately, I never get the optimized charging icon where it stops at 80%. Even though my charging habbits are pretty consistent. What gives?

With the Optimized Battery Charging feature enabled the Apple Watch learns from your daily charging habits to improve the lifespan of the battery of the watch by reducing the time it spends fully charged.

When the feature is enabled, the Apple Watch delays charging past 80% when it predicts it will be connected to a charger for an extended period of time. In these situations, the battery remains between 75% and 80%. The algorithm aims to ensure that the watch is still fully charged when you remove it from the charger.

With the Optimized Charge Limit feature enabled the Apple Watch learns from your daily usage habits and determine when to charge to an optimized limit (80%) and when to allow a full charge. The watch might charge to 100% on some days, and to a lower value on others.
