The charging rates of the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra were examined by GSMArena. They discovered that a 45W fast charger charges the Galaxy S23 Ultra to 68% of its capacity in just 30 minutes. The Galaxy S22 Ultra, in contrast, charged up to 61% in 30 minutes.

There are many small upgrades made by the Galaxy S23 series, but an increase in charging speed is not one of them. The Galaxy S23 still only supports 25W of fast charging, while the Galaxy S23+ and Galaxy S23 Ultra both support 45W. (similar to their predecessors). The Galaxy S23 Ultra still charges a little bit more quickly than the Galaxy S22 Ultra, though.
Even though it’s a small improvement, it still counts. It is comparable to the Xiaomi 12S Ultra, which despite having 67W fast charging, charged 4% more than the Galaxy S23 Ultra.
Samsung’s improved cooling system may be the cause of the slight increase in charging speed in the first 30 minutes. The temperature of the device affects how quickly batteries charge. The Galaxy S23 Ultra can cool down more effectively thanks to its larger heat dissipation system, which results in slightly faster charging speeds. However, despite using a similar cooling system, the charging speeds of the Galaxy S23 and Galaxy S23+ are unchanged.
Using a 45W USB PD 3.0 charger with PPS, the Galaxy S23 Ultra can be fully charged in 59 minutes (Programmable Power Supply). When using the same charger, that figure is comparable to the Galaxy S22 Ultra. And the Xiaomi 12S Ultra is only 9 minutes slower. It takes significantly longer for phones from Apple and Google in the same segment to fully charge.
