I have an ASUS TUF F15 FX506LI and the battery drainage is very fast. Also Diagnosed it and the battery is perfectly fine. But how fast the battery drains is very shocking for a brand new laptop, it cant even stay more than a hour in full battery saver with normal tasks like youtube and browsing at like 40% brightness. Very Disappointed from Asus. Pls I request to fix this issue with a software update atleast increase it to like 3hrs.
