Could anyone please confirm me how much time actually it takes to change MacBook Air M1 brand new?

Interestingly until few days, I used to charge for 45 min and used to get 35% to 85-89% in 45 min. From starting, I am using the same port for my type C mouse. From this week, it is charging slowly (I feel like that). And my charger is getting heated than earlier (while charging).

Day before yesterday I changed my Mac when it was 25%. After 45 min, it charged only till 66%.After I charged for 30 min. It then got 82%. Not sure if this is fine or any issue (on port/charger/any?)

Using macOS Sonoma latest update.

Any idea?

Optimized Battery charging learns as it goes. If not needed it will slow the charge rate in an effort to prolong battery working life.

If you need to charge it now— use the drop down.

The rule of thumb—if you are near the mains leave it plugged in, if you need the portability then run on the battery only—this is how you optimize your battery charging and extend the working life of your battery by reducing the cycle count.
