Yes, you can customize 5G settings on Samsung phones to save battery[1][6][9]. Here's how:
* Turn off 5G: You can turn off 5G when you don't need it, which can save a significant amount of battery, especially in areas with limited 5G connectivity[1]. To do this, go to Settings > Connections > Mobile Networks > Network Mode**[1][9].
* Disable nearby device scanning: Stop your device from constantly searching for nearby devices in the background[1]. Navigate to Settings > Connections > More Connection Settings > Nearby device scanning and toggle it off[1].
* Power Saving Mode: Turning on Power Saving mode disables 5G, among other features, to conserve battery power[6]. You can customize this mode by going to Settings > Battery > Power saving**[1][6].
