By then there will be third party chargers that go to 45W on Samsungs, and I agree that 45W has a very limited advantage as long as 25W is maintained for a large enough portion of a whole charge.
If they bring back the jack though it's enough to sway me back, since the camera upgrade is basically a given and I won't have to struggle between the ROGP2's ugliness and Vivo's UI and 256GB storage limitation, and I'm no longer in a hurry to upgrade.
