If it helps for the battery health to maintain its charge over the years, welcome!
It would be great if the math actually checked out.
0-50% charging time increased by 50%.
0-80% charging time increased by ~36% (.36363636363636)
0-100% charging time increased by 37.5%.
Furthermore, I have no idea what planet you live on, but on Earth, 110 minutes is 1 hour and 50 minutes, not even 2 hours, and certainly not 2.5 hours.
