Testing 45W charger on Galaxy S22 Ultra: Faster charging in just a few minutes

Samsung’s newly launched Galaxy S22 Plus and S22 Ultra have started to support chargers with a maximum capacity of 45W, which seems like a big improvement over previous 25W chargers. However, the 45W charger is not included, which you will have to spend an additional 50 USD to buy. But is the 45W charger worth the upgrade over the standard 25W charger?

Android Authority conducted a practical and in-depth test, to evaluate the 45W charger on the Galaxy S22 Ultra. The smartphone has a 5,000 mAh battery, and it takes 62 minutes to fully charge with a 45W charger, while it takes 70 minutes to fully charge with a 25W charger. It can be seen that the difference is not too big.

The new 45W charger supports Samsung’s Fast Charging 2.0 technology, while the standard 25W charger supports the first generation Fast Charging technology. Both are compatible with the USB Power Delivery PPS standard, which means that you can choose another 45W charger without having to buy genuine Samsung.

Actual testing of Android Authority shows that the maximum capacity of 45W when charging only lasts for a minute, most of the time the charging capacity is only 30W. This explains why the full charge speed of the new 45W charger is not much faster than the standard 25W charger.

That’s not necessarily a bad thing, because maintaining a large charge capacity for long periods of time can shorten the life of the battery. However, it is worth mentioning that users will not get a significant difference if they spend an extra $50 to switch from a 25W to 45W charger.
