I have been using s22 ultra for 8 months with Samsung 45W original charger. Everything was working fine and charging speed was really good. But, Since last two days all of sudden it's not doing cable charging only. I have checked charger and checked fast charging feature enabled as well. I ran Software Diagnostic as well. Showing no issues. 

My phone is on Exynos chip.

@Soorajit: From the notifications, I can see that the estimated charge time is 1hr 27m. With the battery currently sitting at 12%, this seems to be normal.

What colour is the charging ring when you plug the charger in? What does it show in battery section of Device Care? Mine clearly shows super fast charger connected (see screenshot). Please post screenshot of yours.

1h 27m is NOT double 1h 5mins it's only 22 mins more (which is nothing btw).Screenshot_20230317_084402_Device care_1000000687_1679042649.jpg

My understanding ( I'm fallible) is that charging rates are not linear... It will charge at a lower rate as the battery charged state increases.

This screenshot from of a table within https://www.cnet.com/tech/mobile/is-samsungs-45-watt-phone-charger-worth-it-we-put-it-to-the-test/ demonstrates.

I'm not sure why your early experience was different. Screenshot_20230317_095726_Chrome.jpg

Has this problem manifested itself after a recent phone update?

Same charger and cable?
Until the new USB cable marking standard comes into play, it's really hard to tell what amperage the cable supports.

I guess, if your friends model is the same as yours, it's time to speak to Samsung support re warranty.

Good luck!
