45W charger for Samsung Galaxy S22 Ultra only lasts one minute


This is a public service announcement: You may want to forego the $50 Samsung Galaxy S22 Ultra 45W charger.

Despite being a $50 option, Samsung’s new 45W charging for the Galaxy S22 Ultra and Galaxy S22 Plus isn’t looking like much of an increase.

45W charger charged our Galaxy S22 Ultra to 36% in 15 minutes and 67% in 30 minutes during our testing. Compared to the 25W charger with the identical phone, which reached 29 percent in 15 minutes and 58 percent in 30 minutes, there isn’t a huge difference.


And we’re not the only ones that believe this. Using the new 45W charger, the Galaxy S22 Ultra’s 5,000mAh battery can be completely charged in 62 minutes, while the 25W charger takes 70 minutes to do the same. When the wattage of the charger is virtually doubled, an eight-minute time savings doesn’t seem like much.

According to Android Authority, the 45W charger barely managed to maintain its maximum capacity for one minute. The 45W charger’s average continuous output hovers around 30W. So, for an additional $50, it seems like you’re not obtaining the full value of your investment.

To find out why this is the case, we reached out to Samsung. However, Samsung has yet to respond.


A Lithium-ion cell’s lifetime may be extended by not charging it to its maximum power when it is fully charged. As such, adjusting a charger’s power may not be the worst thing in the world.

However, this leaves us wondering whether the 45W charger is worth it if you just require a full charge in less than 10 minutes. While the OnePlus 9 Pro features a 65W charger, you may be better off going with the Oppo Find X5 Pro with its 120W charging or the OnePlus 9 that comes pre-charged.

Because the Galaxy S22 series does not come with a charger, we recommend that you use any of your existing 25W USB-PD standard chargers for the time being.
