The Galaxy Z Fold 8 Ultra features a larger 5,000mAh silicon battery that improves endurance over its predecessor. Samsung’s One UI includes performance profiles, and switching from Standard to Light mode provides a meaningful battery life improvement without sacrificing daily usability. The Light profile reduces processor clock frequencies to save power and manage thermals, while maintaining 120Hz refresh and smooth UI performance.

Unlike Energy Saver mode, it does not throttle performance during regular use and remains inactive when gaming, as Game Booster takes over. After enabling Light mode, the author gained nearly an additional hour of usage per day, eliminating the need to charge before bedtime. The setting is especially beneficial for outdoor use due to better thermal balancing.

Enabling the profile is straightforward: go to Settings > Device care > Performance profile > select Light. This feature is available on all Samsung devices, making it a useful tip for older Galaxy models seeking extended battery life.
