Android Settings to Change on a New Phone

When you first turn on a new Android phone, the default settings are a compromise between what the manufacturer wants and what most people need. Changing a handful of settings in the first hour will improve battery life, privacy, and usability without requiring any technical skill. This guide walks through the most impactful options, from display and notifications to security and storage, so you can set the phone up the way you actually use it.

Why Default Settings Are Rarely Ideal

Android phones ship with a “one size fits all” configuration. Manufacturers enable features like personalized ads, app suggestions, and always-on listening because they increase engagement or revenue, not because they are best for you. Carriers and brands also preload apps that run in the background, consuming data and battery. The defaults are safe and functional, but they are not optimized for privacy, performance, or your personal habits. Taking a few minutes to review settings is the digital equivalent of adjusting the seat and mirrors before driving a new car.

Display and Sound Settings

The screen is the biggest battery drain on any phone, so display settings matter twice: once for comfort, once for power. Start by setting the screen timeout to 30 seconds or 1 minute—anything longer keeps the display burning power when you are not looking at it. Enable adaptive brightness if it is off; it learns your preferences over time and adjusts to ambient light, which prevents the screen from being brighter than needed indoors.

Dark mode: Turn it on if you use the phone at night or have an OLED screen. It reduces eye strain and saves battery on OLED panels because black pixels are literally off.
Refresh rate: If your phone has a 90Hz or 120Hz display, you can often choose between “High” and “Standard.” High feels smoother but uses more battery. Choose Standard if you prioritize endurance.
Font size and display size: Set these to a level where you can read comfortably without zooming. Most people benefit from one step above the default.
Adaptive sound / Dolby Atmos: These audio enhancements are often on by default. If music sounds odd or voices echo, turn them off in Sound settings.

Battery and Performance Settings

Battery life is the most common complaint about new phones, and the fix is usually in the settings, not the hardware. Open Settings > Battery and look for a usage graph. It shows which apps are draining power. From there, you can restrict background activity for apps you rarely use.

Enable Adaptive Battery (or “Battery Optimization”). This uses machine learning to limit power for apps you open infrequently. It is usually on by default, but verify it.
Go to Settings > Apps > See all apps, tap an app you rarely use, and select Battery > Restricted. This prevents it from running in the background.
Turn off Always-on Display if you do not need the clock visible at all times. It can consume 1-2% battery per hour.
Check for a Performance mode toggle. If it is set to “High” or “Turbo,” switch to “Balanced” or “Optimized” for everyday use.

Notifications and Do Not Disturb

Out of the box, every app is allowed to send notifications, which leads to a constant stream of pings. This is not just annoying—it drains battery and fragments your attention. Set aside ten minutes to prune them.

Open Settings > Notifications > App notifications. You will see a list of every app. Turn off notifications for games, shopping apps, and social media that you do not need to hear from instantly.
For apps you keep, tap each one and uncheck Sound and Pop-up if you only want a silent badge.
Set up Do Not Disturb schedules: one for sleeping (e.g., 11 PM to 7 AM) and one for work meetings if you use a calendar. Allow calls from “Starred contacts” only.
Enable Notification history (Settings > Notifications > Notification history). This stores notifications you dismissed accidentally, so you can recover them later.

Privacy and Security Settings

Android 13 and later have a dedicated Privacy dashboard that shows which apps accessed your location, camera, and microphone in the last 24 hours. Review it weekly. The most important changes to make on a new phone are:

Open Settings > Security & privacy > Privacy. Tap Permission manager and go through each permission (Location, Camera, Microphone, etc.). Revoke access for any app that does not need it. For location, choose “While using the app” instead of “Allow all the time.”
Turn off Ads personalization (Settings > Privacy > Ads). This does not stop ads, but it stops Google from using your activity to target them.
Enable Find My Device so you can locate or erase the phone if lost.
Set up a strong lock screen: a 6-digit PIN is better than a pattern. Enable Biometrics (fingerprint or face unlock) for convenience, but keep the PIN as the backup.
Check Google Play Protect is on (Settings > Security > App scanning). It scans apps for malware.

Storage and Backup Settings

New phones often come with 128GB or 256GB of storage, but photos and videos fill that quickly. Set up a backup strategy before you need it.

Open Settings > System > Backup. Make sure Back up to Google Drive is enabled. This backs up app data, call history, and settings.
For photos, open the Google Photos app, tap your profile picture, go to Settings > Backup, and choose Backup quality. “Storage saver” compresses images but gives you unlimited storage (on older plans); “Original quality” uses your Google account storage.
If you take a lot of videos, consider setting Photos to back up only on Wi-Fi to avoid mobile data charges.
Check Settings > Storage to see what is taking space. You can move apps to an SD card if your phone has a slot, but this is rare on modern flagships.

Connectivity and Network Settings

Wi-Fi, Bluetooth, and mobile data settings affect both battery and security. The defaults are usually fine, but two changes are worth making:

Turn off Wi-Fi scanning and Bluetooth scanning (under Settings > Location > Wi-Fi and Bluetooth scanning). These let apps and Google scan for networks even when Wi-Fi is off, which uses battery and reveals your location.
Set Mobile data to “Wi-Fi preferred” if your carrier offers that option. This prevents the phone from using 5G when Wi-Fi is weak but available.
If you travel internationally, disable Data roaming to avoid surprise charges. You can re-enable it when you need it.

Frequently Asked Questions

Should I disable pre-installed apps?

You can disable many apps that came with the phone (like Facebook, Netflix, or carrier apps) by going to Settings > Apps, tapping the app, and choosing “Disable.” This stops them from running and updating. You can re-enable them later. If the button is grayed out, the app is a system app; you can only uninstall updates, not the app itself.

Does dark mode save battery on all screens?

No. Dark mode saves battery only on OLED (organic light-emitting diode) screens, where each pixel emits its own light and black pixels are off. On LCD screens, the backlight stays on regardless of the color, so dark mode saves almost nothing. Most modern mid-range and flagship phones use OLED, but budget models often use LCD.

How do I stop apps from tracking my location?

Go to Settings > Security & privacy > Privacy > Permission manager > Location. Tap each app and change the permission to “While using the app” or “Deny.” For apps that need location in the background (like weather apps), you can set it to “Allow all the time” but then revoke it after the app updates. Also turn off Wi-Fi and Bluetooth scanning under Location settings to prevent passive tracking.

Why is my battery draining fast after setup?

For the first 24-48 hours, a new phone syncs all your data, downloads app updates, and indexes photos. This is normal. If it continues after a few days, check the battery usage graph in Settings > Battery to see which app is using the most. Often it is Google Play Services or a social media app running in the background. Restrict that app’s background activity or uninstall it.

Should I use a third-party launcher?

A launcher (like Nova Launcher or Microsoft Launcher) replaces your home screen and app drawer. It can make the phone feel faster and more customizable, but it does not change system settings or battery life significantly. If you are happy with the default launcher, there is no need. If you want gesture controls or a different grid size, a third-party launcher is a safe, reversible choice.

How often should I update the Android system?

Install system updates as soon as you get the notification, especially security patches. They fix vulnerabilities and bugs. You can check manually in Settings > System > System update. If you are worried about battery life after an update, give it a day or two; background optimization often runs after a major update.
