Samsung S21 Ultra vs Note 20 Ultra vs iPhone 12 Pro Max vs Mi 11 vs Mate 40 Pro Charging Speed Test.
The S21 Ultra has extremely good battery life, but what about it’s charging speed? Well, its still on 25W charging and this time it’s not in the box, but I have the 25W block and will be putting it up against the Samsung Note 20 Ultra (25W), iPhone 12 Pro Max (20W), Xiaomi Mi 11 (55W), and Huawei Mate 40 Pro (66W) in this Epic Charging Speed Test! – Which Phone do YOU Think WILL Charge the FASTEST? All phones have been set to Auto-Brightness, lowest possible resolution and refresh rate, and all have been put into Airplane mode. Battery Charging Optimizations have been disabled.
