First time charging ipad 2020 pro
How long should i charge my ipad pro 2020 before using it for the first time ?
iPad Pro 12.9-inch, 3rd Gen, Wi-Fi, Cell
Don't worry about it, Having to charge it a long time before use was something you had to do for battery with a completely different technology. (those batteries have not been used in any products for a really long time)
Just use it! :D
