Android Settings Most People Never Touch But Should in 2026
Android phones come with dozens of settings configured for the average user rather than the optimal user. Most people never go deeper than WiFi, Bluetooth and brightness. The settings in this guide are the ones that are already on your phone, require no extra apps, and produce real improvements in battery life, performance, privacy and daily comfort once changed. After systematically going through every settings menu on three different Android phones, these are the ones worth your time.
How We Identified These Settings
We went through every settings screen on a Pixel 7a running Android 14, a Samsung Galaxy A54 running One UI 6, and a Redmi Note 13 running MIUI 14 and documented every setting that met two criteria: the default value is suboptimal for most users, and changing it produces a measurable or clearly noticeable improvement. Settings were changed one at a time over several weeks and evaluated for real impact before inclusion.
Note on manufacturer differences: Samsung One UI and Xiaomi MIUI put settings in different locations than stock Android. Where paths differ significantly this is noted. If a setting is not found at the path listed, use the search function in your Settings app to find it by name.
1. Adaptive Battery
Settings then Battery then Adaptive Battery. When enabled Android learns which apps you use regularly and which you open occasionally, then restricts background activity for apps you rarely use. Over two to three weeks of learning your patterns it reduces unnecessary background processing from apps that are technically allowed to run but that you never actually check. The improvement in battery life is gradual rather than immediate but after two weeks the difference is measurable, typically 30 to 60 minutes of extra screen-on time.
This is on by default on Pixel phones but often off or configured differently on Samsung and Xiaomi devices. Worth verifying it is enabled regardless of your phone brand.
2. Notification History
Settings then Notifications then Notification History. Android can keep a log of every notification you receive for the past 24 hours, even ones you accidentally dismissed. This feature is off by default. Enabling it means when you swipe away a notification without reading it and then wonder what it said, you can find it in the history log. Particularly useful for WhatsApp messages, calendar reminders and OTP codes you dismissed too quickly.
3. Smart Replies and Suggested Actions
Settings then Notifications then Allow Notification Snoozing and Suggested Actions. When enabled Android adds one-tap quick reply buttons to message notifications and contextual action buttons to other notifications. A map link in a notification gets an Open in Maps button. A phone number gets a Call button. This reduces the number of taps needed to act on notifications without opening the full app. Small improvement individually but meaningful over dozens of daily notifications.
4. Restrict Background Data Per App
Settings then Network then Data Usage then app name then Background Data. Disabling background data for specific apps stops them using mobile data when you are not actively using them. Social media apps, news apps and streaming services all check for new content in the background constantly when on mobile data. Restricting them saves meaningful amounts of data over a month and slightly improves battery life. The apps still fully function when you open them; they just do not consume data in the background while you are not looking.
5. DNS over TLS (Private DNS)
Settings then Network then Private DNS then Private DNS Provider Hostname. Enter dns.google or 1dot1dot1dot1.cloudflare-dns.com. This encrypts DNS queries so your internet provider cannot log every website and service your phone accesses. The change also often produces faster domain resolution than the default ISP DNS. Takes 30 seconds to set and applies to every app on the phone automatically. One of the highest-impact single settings changes for privacy with zero downside in normal use.
6. Tap to Wake and Lift to Wake
Settings then Display then Tap to Wake and Lift to Wake. Enabling both means you can wake your phone by double tapping the screen or picking it up rather than pressing the power button. Minor convenience but one of those things that you notice constantly in daily use once you have it. On phones where the power button is awkward to reach (larger phones with side-mounted buttons) this change reduces the number of times you fumble for the button per day by a surprisingly large amount.
7. Scrolling Screenshots
On Samsung and many Android phones running Android 12 and above, after taking a standard screenshot a Scroll button appears at the bottom of the preview. Tapping it extends the screenshot down automatically, capturing content below what was visible on screen. Useful for capturing long conversations, full web pages, receipts or any content that does not fit on a single screen. The resulting image is a single long screenshot rather than multiple separate ones.
On Pixel phones this is available through the screenshot editing tool that appears after capture. Different manufacturers place the option differently but it exists on most Android phones running Android 12 or later.
8. App Pinning for Shared Use
Settings then Security then App Pinning (or similar, varies by manufacturer). After enabling, open an app, long press the recent apps button, tap the app icon at the top of the card and select Pin. The phone locks to that app and cannot navigate away without entering the PIN. Useful when handing your phone to someone to show them a specific video, letting a child use one app, or demonstrating something to someone without giving them access to the rest of the phone.
9. Colour and Contrast Accessibility Settings
Settings then Accessibility then Colour and Motion. Beyond accessibility use cases these settings include options like Bold Text, High Contrast Text and Display Size that affect readability for everyone, not just users with visual impairments. Increasing display size slightly makes text easier to read without squinting in bright outdoor conditions. Bold Text makes interface text clearer on lower-resolution screens. These are improvements for everyday use that happen to live in the Accessibility menu.
10. Developer Options: USB Debugging Off
If you have previously enabled Developer Options (which this guide has mentioned for animation settings), check that USB Debugging is off unless you specifically need it. Settings then System then Developer Options then USB Debugging. When USB Debugging is on, any computer your phone connects to via USB can potentially access the phone’s data more deeply than normal. Leaving it on when not actively developing creates an unnecessary security exposure. Turn it on when you need it, turn it off when you do not.

Pros and Cons
What is good: every setting here is built into Android, costs nothing to change, and most are reversible instantly if you do not like the result. The Private DNS setting is particularly valuable because it is a single change that improves privacy for every app and every connection on the phone simultaneously without requiring any additional software.
What to know: some settings paths vary significantly between Samsung One UI, MIUI and stock Android. The Settings search function on any Android phone will find any setting by name faster than navigating menus. If a setting is not at the path listed, search for it.
Who Should Go Through These Settings
Anyone who set up their Android phone using the default setup wizard and has never gone back into settings since. People who want to improve battery life without buying a new phone. Users who care about privacy and want changes that work at the system level rather than requiring ongoing attention. Anyone who hands their phone to others regularly and wants more control over what can be accessed.
Final Verdict
Set Private DNS to Cloudflare right now. It takes 30 seconds, improves privacy immediately for every app on your phone, and costs nothing. Then enable Notification History so you stop losing dismissed notifications permanently. Enable Adaptive Battery if it is not already on. Those three changes cover the highest-impact improvements from this list with the least setup time. Work through the rest on a weekend when you have 30 minutes and you will have a phone that works better in daily use than it did out of the box.
Frequently Asked Questions
Will changing these settings void my warranty?
No. All settings in this guide are standard Android configuration options. None involve rooting, modifying system files or installing anything outside official app stores. Every change is reversible through the same settings menu.
Does Private DNS affect my internet speed?
It often improves page loading speed slightly because Google DNS and Cloudflare DNS servers are generally faster than ISP-provided DNS. The encryption overhead is negligible on modern processors. In testing on three phones there was no perceptible slowdown and some modest improvement in resolution speed for frequently visited domains.
How do I find settings that are in different places on my Samsung or Xiaomi phone?
Open your Settings app and tap the search icon (magnifying glass) at the top. Type the name of the setting you are looking for. The search function works across all settings on most Android phones and is faster than navigating menus when you know what you want but not exactly where it lives.
Is it safe to enable App Pinning?
Yes. App Pinning is a security feature designed specifically to make sharing your phone safer. It does not expose any additional security surface. The PIN requirement to unpin means someone who picks up your pinned phone cannot navigate away without your authentication.
