Check and adjust your battery settings. By default, the fast charge option is disabled, and the suoer fast is enabled. make the adjustments as per your liking. If you ask me, i charge my phone slow. I charge itnusing 10 watts charger, 5 volts and 2 amps which is almost 0,5C (1C is the full capacity of the battery, 0,5 C is half the capacity) and it works great for me. No heat build up, minimum wear and tear, reliable and solid charge, about 2 and a half-ish hours charge time. I hate to say it, but US support are dumb, and have no knowledge and understanding on the charging process and cannot compute in mind simple and basic mathematics about 1C and 0,5C charging times and so on. BEFORE you jump on me, this charging mode is ALLOWED by Samsung. This charging mode is achieved if you disable fast charging and suoer fast charging in the batery settings, available by default for the user to manage. This is my go to charging mode. i use fast or super fast, only in emergencies, when i need my phone brought up quickly, but in the other cases i am slow charging. I charge overnight and in my general use, i get it 2 days use before i charge it again. This is how much i use the phone. make few phone calls, i take few photos, I do some light browsing, some whatsapp, and i have removed or disabled all and any apps i don't use. basically i am light user.
I disagree,
15 watts is fast charging. S22 Ultra identify it as fast charge. The 15 watts charger says "Adaptive Fast Charge"
25 watts is Samsung Super Fast Charge 1.0
45 watts is Samsung Super Fast Charge 2.0
10 watts charging, is allowed by Samsung and it is achived by S22 ultra by disabling fast charge and super fast charge options is the regular charge, 0,5C charge.
