In this guide, we will show you the steps to fix the battery drain issue on your Samsung Galaxy device running One UI 5.0. The latest iteration of the OS has just been released by the South Korean giants. Based on Android 13, it brings in a slew of noteworthy features, UI changes, and under the hood improvements to the system.
On the flip side though, a few bugs and issues have crept in as well. Among them, it is the excessive battery drainage that has been a cause of corner for many users. Upon doing a few battery tests over a day, we might have found the culprit- it is the Ultra Wide Band [UWB] system app that is constantly running in the background and hogging an astronomical amount of battery.
So what exactly is this UWB? Well, Ultra Wide Band is a short-range, wireless communication protocol that functions through radio waves. As opposed to WiFi and Bluetooth, it operates at very high frequencies and is also much more secure and accurate than its counterpart.
UWB was first introduced in the Galaxy Note 20 Ultra and has since made its way to the S21+, S21 Ultra, and the recently released S22 series [apart from a few other non-Samsung devices]. However, since it is the reason behind the battery drain issue on your Samsung Galaxy device running One UI 5.0, you should take the restrictive measure and disable or at least force stop this app. Here’s how it could be done.
