My S21 Ultra is taking 1.5 hours to charge from 5-100% with the Samsung 25W super fast charger and the cable supplied with the S21 Ultra.
And I have fast charging and super fast charging enabled on my device.
Any idea what I may be doing wrong?
I have a S21 Ultra and since 2 weeks ago it starts to charge very slowly. I have 3 Samsung 25W, I tried all 3 and the problem persists. When is with the screen off it charges normally. If I'm browsing, for instance Chrome, it can spend more than 3 hours until reach 100%. What could it be? Why it slows down so much? Thanks
