Samsung introduced a lot of subtle improvements with the Galaxy S23 and its pre-loaded One UI 5.1 interface. One of the new features includes a charging bypass option on the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra. The feature could be very helpful for gamers or anyone who wants to take extra care of the battery.
The Pause USB Power Delivery feature, which can be found in Galaxy S23's Game Booster settings (spotted by NL Tech), allows the phone to supply the input power directly to the processor. This means that the phone's battery won't get charged when this feature is active. Bypassing the charger's power directly to the chipset generates less heat, thereby leading to improved thermals and better sustained performance.
It also helps with battery health. When the phone isn't continuously charged, it reduces battery charge cycles, which keeps the battery healthy in the long run. This feature is currently only available on the Galaxy S23 series. We are not sure if it is restricted to newer hardware or if a newer version of Game Booster will also bring the feature to older phones.
As shown in the image below, the Galaxy S23 Ultra consumes 6W of power when the battery bypass feature is enabled. But when the feature is disabled, the smartphone consumes 17W of power. Hopefully, Samsung brings it to more Galaxy smartphones and tablets in the future. And it is weird to see Samsung not even mentioning this feature in its launch event or One UI 5.1 changelog.
