Samsung Galaxy S22 phones don’t seem to be charging much faster with high-power adapters
Charging your smartphone sureseemslike it should be straightforward, right? Everything else being equal, the more power you can throw at the problem, the faster your handset should charge — a devicesupporting 150W inputhad sure better charge a hell of a lot faster than one with dinky old 10W support. At least, that all sounds perfectly logical, but some tests with the brand-newSamsung Galaxy S22phones are not showing the improved speeds we’d expect from their 45W charging support.

The tests looked at charging performance with both the S22+ and S22 Ultra paired with one of three chargers: a Samsung 25W adapter, a Samsung 45W adapter, and a 65W USB-PD adapter (thoughlacking PPS). Upon trying out those combinations in setups that both looked at how long it takes to fully charge the phones, as well as how much of a charge they can amass in 30 minutes, the results show a stunningly even playing field: a difference of just 5% between the best and worst performers in the quick-charge test, and a difference of only 5 minutes at reaching a full charge.
Considering that Samsung’s 45W adapter should be nearly twice as powerful as its 25W offering, we’d sure expect to see a bigger improvement than just shaving a mere 5 minutes off the S22 Ultra’s full-charge time. This is far from the first time thatSamsung users have had cause to be confused and disappointedover the mismatch between claims of high-speed support and what we got in terms of real-world performance, but it’s nonetheless still upsetting.
We’ve reached out to Samsung to see if it has any comment on this charging behavior, and will update this post if we get any response.
