Galaxy S26 Settings to Change Right After Setup

If you just bought a Galaxy S26, the first thing you should do is change a handful of settings that affect battery life, privacy, and everyday usability. This article walks you through the most impactful ones, from disabling unnecessary background activity to tweaking the Always-On Display and notification behavior. These are general recommendations based on Android and One UI settings that have been consistent across recent Galaxy flagships; exact menu names may vary slightly depending on your carrier and software version.

Why Bother Changing Settings on a New Phone?

Out of the box, a Galaxy S26 is configured to appeal to the broadest possible audience, which means many features are enabled by default even if you won’t use them. That costs you battery life, data, and sometimes privacy. For example, app optimization, personalized ads, and 5G standby all draw power in the background. Changing a few key settings right away can add an hour or more of screen-on time per charge and reduce the number of notifications you have to dismiss. It also helps you avoid the “new phone slowdown” that often comes from dozens of apps syncing at once.

Battery and Performance Settings

The most requested change is usually battery optimization. On the S26, go to Settings > Battery and device care > Battery. Here you can enable Adaptive battery, which learns your usage patterns and limits background activity for apps you rarely open. Also consider turning on Adaptive power saving — it automatically switches to a lower resolution and refresh rate when you’re not actively using the screen. Many users also disable 5G when they’re on Wi-Fi most of the day, because 5G standby can drain the battery noticeably. You can do this in Settings > Connections > Mobile networks > Network mode, choosing LTE/4G instead of 5G. If you prefer a more aggressive approach, set the processor to Optimized rather than Maximum in Settings > Battery and device care > Device care > Performance profile (the exact label may be “Performance mode” on some versions).

Display and Always-On Display

The S26’s AMOLED screen is beautiful, but it’s also the biggest battery consumer. Go to Settings > Display and consider these tweaks:

Set Motion smoothness to Adaptive (it already is by default) so the refresh rate drops to 60Hz when you’re reading static content.
Turn off Adaptive brightness if you prefer manual control, or keep it on but reduce the maximum brightness in Settings > Display > Brightness.
For the Always-On Display (AOD), go to Settings > Lock screen > Always-On Display and choose Tap to show instead of Always show. This saves a surprising amount of battery because the screen stays completely off until you tap it.
If you want to save even more, switch to Dark mode under Settings > Display > Dark mode. On an OLED panel, dark pixels are literally turned off, so dark mode reduces power consumption.

Notifications and Do Not Disturb

A new phone often bombards you with notifications from every app you install. To take control, open Settings > Notifications and review the list. You can tap each app and toggle off Allow notifications for ones you don’t care about. For a more systematic approach, use Notification categories (if available) to disable only certain types, like promotional alerts. Also set up Do Not Disturb (DND) in Settings > Notifications > Do Not Disturb. Schedule it for your sleeping hours, and customize which contacts or apps can break through. Many users also enable Notification history in Settings > Notifications > Advanced settings so you can review missed alerts later.

Privacy and Security

Privacy settings are often overlooked during initial setup. Go to Settings > Privacy and review the following:

Permission manager — see which apps have access to your camera, microphone, location, and body sensors. Revoke any that seem unnecessary.
App permissions — for each app, choose Allow only while using the app for location and camera instead of Allow all the time.
Personalization services — turn off Personalized ads and Customization service (Samsung’s ad tracking) if you don’t want your usage data used for ads.
Lock screen — set a strong PIN or password in Settings > Lock screen > Screen lock type. Consider enabling Fingerprints or Face recognition for convenience, but remember that a strong PIN is the fallback.

Also enable Find My Mobile in Settings > Biometrics and security > Find My Mobile so you can locate, lock, or wipe the phone remotely if lost.

App Management and Bloatware

New Samsung phones come with a lot of preinstalled apps, some of which you may never use. You can disable them (not uninstall) via Settings > Apps, selecting the app and tapping Disable. This stops them from running in the background and updating. Common candidates include Facebook, Microsoft Office, and various Samsung apps you don’t need. Be careful not to disable system-critical apps like Settings or the Phone app. Also, go to Settings > Battery and device care > Memory and enable RAM Plus (if available) to use some storage as virtual RAM, though this is more useful for heavy multitasking than for everyday use. For most people, leaving it at the default is fine.

Connectivity and Location

Bluetooth, Wi-Fi, and GPS scanning can drain battery even when you’re not using them. Go to Settings > Connections and turn off Wi-Fi scanning and Bluetooth scanning under Location > Improve accuracy unless you use location-based features that rely on them. Also, consider turning off Nearby device scanning if you don’t use SmartThings or similar features. If you’re traveling, you might want to disable Roaming under Mobile networks to avoid unexpected charges. For privacy, you can set Location to Battery saving mode (which uses Wi-Fi and mobile networks instead of GPS) in Settings > Location > Mode, but note that this reduces accuracy for navigation.

Frequently Asked Questions

Will changing these settings void my warranty?

No. All settings changes described here are standard user options. They do not modify the system partition or require root access, so your warranty remains intact.

How do I get the best battery life without sacrificing features?

Start with Adaptive battery, Adaptive power saving, and AOD set to Tap to show. Then disable background activity for apps you rarely use via Settings > Apps > [app] > Battery > Restricted. You’ll typically see a significant improvement without losing notifications or performance.

Why is my S26 still hot after setup?

During the first 24-48 hours, the phone is indexing files, syncing accounts, and installing updates, which can cause temporary heat and battery drain. If it persists after a few days, check for rogue apps in Settings > Battery > Battery usage and consider a factory reset if nothing helps.

Should I disable 5G?

If you’re on Wi-Fi most of the day or your 5G signal is weak, disabling 5G can improve battery life. You can always re-enable it when you need faster mobile data. For most users, the difference is noticeable but not dramatic.

What is the best way to clean my new phone’s screen?

Use a soft, lint-free microfiber cloth slightly dampened with water or a screen-safe cleaner. Avoid paper towels, alcohol-based wipes, or abrasive materials, as they can damage the oleophobic coating.
