Wireless charging s21 ultra

[reveshawn]

I recently  bought the latest 9w single wireless charger pad for my s21 ultra and the system shows 2hours and 21 mins to fully charge my s21 ultra but it took 3 hours 41mins and 26.95 seconds. So that's  not reasonable. TAKE NOTE: wifi and data is off and I'm  not using my phone. I'm not at a room temperature  with fan and it's not in here

Hey there! Amazing day! Thank you for the feedback. As for your concern, there are certainly many factors that may affect the overall charging time when it comes to using wireless charging pads. One of which is the additional casing of your device, room air temperature, minimal device processes, device's position on the charging pad, age of the phone, and battery.

it should be since it's just a 9w wireless charger.
Should have bought the 15w wireless charger, it's the maximum wireless charging speed supported by S21U.

Do you also use wireless charger?

Can you recommend me best 15w wireless charger that works well with s21 ultra and may i ask how long does it take to full charge in 15w wireless charger? Is there much difference?

I'd recommend samsung's fast wireless charging stand

Im using the duo, not a fan of wireless charging tho.

How many wattage has the duo? Wireless charging for me is just very convenient hehe. Can I ask how long your s21 ultra takes everyday in terms of battery and the Screen on time for your daily usage?

the Duo supports max of 12w on the main and 7.5w on the smaller pad.

on a regular use my 21ultra I got an average of 7hrs SOT with 30% batt remaining.
