If Power Saving Mode on your Samsung Galaxy S26 Ultra is not working, your battery may drain faster than expected. You might notice that background apps keep running, or performance does not change at all. This usually happens due to conflicting settings or minor software glitches in One UI 8.5.
The good news is that you can fix this with a few simple adjustments.
Why Your Samsung Galaxy S26 Ultra Power Saving Mode Is Not Working
- Power Saving Mode is not fully enabled or applied.
- Background usage limits are turned off.
- Adaptive Battery or performance settings are conflicting.
- Software glitches after a recent update.
- Certain apps are overriding battery restrictions.
1. Enable Power Saving Mode Properly
Power Saving Mode only works when all its restrictions are applied. If it is partially enabled, your phone may not limit performance or background activity as expected.
Open Settings, and then tap Battery.
Tap Power saving, and then toggle it on.
Scroll down, and then enable all available restrictions such as limiting CPU speed and reducing brightness.
2. Restart Your Phone
A quick restart can fix temporary issues affecting battery management. It refreshes system processes that control Power Saving Mode.
Swipe down from the top right to open Quick Settings, and then tap the Power icon.
Tap Restart, and then wait for the device to boot up completely.
After restarting, enable Power Saving Mode again and check if it works.
3. Check Background Usage Limits
If apps are not restricted, they can continue running even when Power Saving Mode is on. This reduces its effectiveness.
Open Settings, and then tap Battery.
Tap Background usage limits, and then enable Put unused apps to sleep.
You can also add apps to Deep sleeping apps for stronger restrictions.
4. Turn Off Adaptive Battery Temporarily
Adaptive Battery sometimes overrides manual battery settings. Disabling it can help Power Saving Mode work properly.
Open Settings, and then tap Battery.
Tap More battery settings, and then toggle off Adaptive battery.
Turn Power Saving Mode back on and observe any improvements.
5. Check for Software Updates
System updates often fix bugs that affect battery features. Running outdated software can cause Power Saving Mode to behave incorrectly.
Open Settings, and then tap Software update.
Tap Download and install, and then install any available updates.
Restart your phone after the update to apply changes.
6. Reset Battery Settings
If the issue continues, your battery settings may be misconfigured. Resetting them can restore proper behavior.
Open Settings, and then tap General management.
Tap Reset, and then tap Reset all settings.
Confirm the reset, then enable Power Saving Mode again and test it.
Power Saving Mode should help extend your battery life without effort. Once properly configured, it will limit background activity and reduce power consumption automatically.
FAQs

Does Power Saving Mode affect performance?
Yes, it lowers CPU speed and reduces background activity. This helps save battery but may slightly reduce performance.
