It's not like all Galaxy S20 Ultra owners took advantage of 45W charging. The company only shipped the 25W charger in the box. So if you wanted the extra speed, you had to buy the 45W charger separately.

Chargers for Galaxy S21 Series in 2022 The 14 Best Wireless Chargers for Galaxy S21 Series in 2022

Some might have expected the Galaxy S21 and Galaxy S21+ to get 45W fast charging. Their predecessors maxed out at 25W. If Samsung were to ensure continuous improvement of their features, perhaps it would offer higher charging speeds. It doesn't. Both of the new flagships can charge your phone at a maximum of 25W. Last but not the least, here we have for you the KKM wireless charger stand with a 15W power output. This wireless charger can charge any Qi enabled smartphone across different brands at a decent pace. However, it is recommended to use the Galaxy S21 fast charger for the best charging experience on the concerned Samsung device. As with the other wireless charging stand, you can charge your Galaxy S21 smartphones, vertically or horizontally. With the vertical charging feature, you can use a wireless charger as a stand to enjoy video calls and more. What I love the most about this car wireless charger is the automatic opening and closing design. With the presence of trapezoidal structure clamps and anti-vibration rubber on both arms, your smartphone will remain steady. The most important thing when buying your charger, or re-using an old one, is to make sure it's fully compatible. The case-friendly design ensures there is no need to remove the case before charging the device (15W). Courtesy of the double suction cup, you can comfortably place it on the dashboard or windshield. Taking everything into account, WAITIEE stands out as a proficient car wireless charger for S21 Ultra.

Whether you prefer to have a simple flat charging mat or like to have a useful charging stand so that you can enjoy hands-free video-calling or movie-streaming even when your device is being powered up, Spigen Convertible Fast Wireless Charger is for you. Based on your needs, you can convert it into a flat charging mat or turn it into a neat stand to prop up your smartphone. Perhaps fewer people bought the charger than it had hoped, leading Samsung to realize that the lure of 45W speed wasn't enticing customers. Then again, the 45W charger didn't offer much over the 25W anyway. The Galaxy S21 Ultra can be charged wirelessly at up to 15W. Therefore, it is recommended that you choose a wireless charger with similar or more power output. Please note that the 15W fast wireless charging will be delivered when the phone is in the sweet spot. Otherwise, it will revert to 10W wireless charging.

Don't let your battery completely drain. With new lithium-ion batteries being used, it is better to keep the battery partially charged, instead of letting it run out completely. When possible, charge your device in small amounts to keep the battery from depleting. If the power has been depleted, the battery charging indicator may take up to 10 minutes to appear on the phone or tablet's screen while charging.
