Samsung Galaxy users can enhance their device's battery life by adjusting specific settings in the OneUI interface. By default, Samsung devices use a "Standard" performance profile that balances processing speed, battery life, and cooling. However, this setting may use more power than needed for everyday tasks. An alternative profile called "Basic" focuses more on battery conservation and cooling, though it might slightly slow down performance. Users can switch to this profile by going to **Settings > Device Maintenance > Performance Profile > Choose Basic**. Another way to improve battery efficiency is by limiting the activity of background apps. Through the Battery menu in OneUI, users can identify apps that consume the most power and reduce their background activity. This can be done by putting unused apps to sleep or into a deeper sleep mode after a period of inactivity. To manage these settings, users should go to **Settings > Battery > Background Usage Limits**, where they can enable the "Put unused apps to sleep" option and select specific apps for deep sleep. Reducing unnecessary notifications for these apps can also help save battery and data. A third approach is using the power saving mode, which can be turned on manually or set to activate automatically. This mode reduces smartphone functions such as screen brightness, background network use, app synchronization, and geolocation to conserve battery. There are two power saving modes available: Standard and Maximum, each offering different levels of restrictions. Users can access and customize this mode by navigating to **Settings > Battery > Power Saving**, where they can choose and adjust the desired mode. An adaptive version of the power saving mode can also be enabled, allowing the device to activate it based on the user's habits and battery levels.
