Steps
Open the Galaxy Store, search for Samsung Keyboard and tap Update. Samsung confirmed this app was causing heavy drain after the April 2026 patch, so do this first.
Go to Settings, Connections, More connection settings, then turn off Nearby device scanning. It keeps hunting for accessories and wearables in the background.
Open Settings, Connections, Wi-Fi, tap the three-dot menu and choose Advanced settings. Turn off Wi-Fi scanning, then do the same for Bluetooth scanning under the Bluetooth menu.
In Settings, Connections, More connection settings, tap Print and turn off Default print service. It runs in the background even if you never print from your phone.
Open Settings, Notifications, App notifications and switch off alerts for shopping, games and any app you do not need pinging you.
Go to Settings, Apps, find Digital Wellbeing and open its permissions. Remove usage access so it stops tracking everything you open.
Open Settings, Battery, turn on Adaptive Battery and enable the Light performance profile. Light mode trims background power without slowing down normal use.
In Settings, Battery, Background usage limits, tap Deep sleeping apps and add the apps you rarely open. They will only run when you launch them.
Set Always On Display to Tap to show under Lock screen and AOD, then open Battery, Auto optimization and switch on Auto restart with a nightly schedule.
After any update, clear the cache for your five or six most used apps in Settings, Apps, Storage, and wipe the cache partition from recovery mode. Your files and accounts stay untouched.
Tips and common mistakes
If your phone is less than two weeks old, leave these settings alone for a while and let Adaptive Battery learn your habits first.
Do not force close apps from the recent apps screen, because relaunching them costs more power than leaving them cached.
Keep adaptive brightness on and keep 120Hz enabled, since the screen settings save far less than background scanning does.
A quick extra step after a bad update is running Galaxy App Booster from the Good Guardians app.
Questions
Why did my battery get worse right after an update?
A buggy system app, often the Samsung Keyboard, can keep the phone awake in the background. Updating that app and clearing caches usually brings usage back to normal within a day or two.
Do I need to drop to 60Hz or lower the screen resolution?
No. Refresh rate and resolution make very little difference next to background scanning and notification wake-ups, so keep the smooth 120Hz display on.
Should I just leave power saving mode on all the time?
It is not necessary once these settings are in place, and it limits features you paid for. Use it only when you are far from a charger.
