How to Fix Galaxy S25 Ultra Power Saving Mode Not Working

Power Saving Mode helps extend your Galaxy S25 Ultra’s battery life by reducing performance and limiting background activity. But when it stops working, your phone might drain faster than usual, even when the feature is turned on.

If that sounds familiar, it’s usually caused by misconfigured settings, app conflicts, or outdated software. Here’s how to fix it and make Power Saving Mode work properly again.

Why Power Saving Mode Might Not Be Working

• The Power Saving Mode switch is off or set incorrectly.
• Background apps are consuming too much power.
• Battery optimization settings are disabled.
• Software bugs or outdated system version.
• Third-party apps interfering with battery control.

Turn On Power Saving Mode Properly.

Sometimes, Power Saving Mode isn’t fully activated, even when it appears to be on. Ensuring it’s enabled correctly can restore its function.

1. Open Settings, and then tap Battery and device care.
2. Tap Battery, and then toggle on Power saving.

You can also tap Power saving to review the options underneath, such as Limit apps and home screen or Turn off Always On Display, and make sure they’re enabled for maximum effect.

Check Background App Activity.

Certain apps that run continuously can prevent Power Saving Mode from doing its job. Limiting their background activity helps save battery more effectively.

1. Open Settings, and then tap Battery and device care.
2. Tap Battery usage, and then review which apps consume the most power.

Tap an app that drains too much battery, and then select Restrict background usage. This will prevent it from running when not in use.

Disable High Performance Mode.

If High Performance Mode is turned on, it overrides Power Saving Mode. You’ll need to disable it for the battery saver to work.

1. Open Settings, and then tap Battery and device care.
2. Tap Battery, and then tap Performance profile.

Select Optimized or Light instead of High performance. After changing this, Power Saving Mode should start working as intended.

Restart Your Phone.

A simple restart can often clear background processes or small system glitches that interfere with Power Saving Mode.

1. Swipe down from the top-right corner of the screen to open the Quick Settings panel.
2. Tap the Power icon, and then tap Restart.

After your phone reboots, enable Power Saving Mode again and observe if battery life improves.

Update the Software.

Outdated firmware or bugs can cause system features like Power Saving Mode to malfunction. Updating ensures stability and compatibility.

1. Open Settings, and then tap Software update.
2. Tap Download and install, and then follow the prompts if an update is available.

Once installed, restart your phone to apply the update.

Reset All Settings.

If none of the methods work, resetting all settings can help by clearing out any conflicting configurations without erasing personal data.

1. Open Settings, and then tap General management.
2. Tap Reset, and then tap Reset all settings.

This restores all system preferences to default, including battery settings.

A properly working Power Saving Mode helps your Galaxy S25 Ultra last longer throughout the day. After applying these steps, your phone should manage power more efficiently again.
