Hello, thank you for your feedback. I understand your concerns on your device charging speed and I will be more than happy to take a look into this with you.
Please Note: Not all devices support 45W charging, however your device will automatically choose the best charging speed it supports when plugged into a higher rated charger.
Most Galaxy phones can use the fast charging technology in Samsung chargers, and most phones support Fast wireless charging when you really need your device to be up and running again. When you plug your device into a Samsung Fast Charger, your phone will automatically turn on the Fast cable charging feature. This feature should be on by default, but you can also turn it on manually.
Superfast charging is only available on select device, and you will need to use a 25W or 45W Samsung-approved adapter.
