Buying a new smartphone is an exciting experience. You take it out of the box, power it on, and rush through the setup screens, tapping “agree” and “allow” to get to your home screen as quickly as possible. Most of us rarely give those initial permissions a second thought. However, smartphones come out of the box optimized for the manufacturer, not the user.
Your device is likely running dozens of background processes right now. It is tracking your daily commute, scanning for nearby networks, and sending diagnostic data back to corporate servers. While some of these features offer minor conveniences, they often come at a steep cost to your battery life, mobile data allowance, and personal privacy. Tech companies rely on the fact that most users will never dig into their system menus to change these defaults.
Taking a few minutes to adjust your preferences can drastically improve your daily phone experience. You will notice your battery lasting longer throughout the day, your data usage dropping, and your personal information remaining more secure. This guide walks you through the hidden mobile settings you need to disable immediately, with easy steps for both iOS and Android users.
Location Tracking and History
Your phone is constantly keeping tabs on where you go, how long you stay there, and the routes you take to get back home. While map applications obviously need this data to function, your device also tracks this information at a system level.
Significant Locations (iOS)
If you use an iPhone, Apple tracks the places you visit most often to provide location-related insights in apps like Maps and Calendar. The company encrypts this data, but many users feel uncomfortable knowing their device keeps a detailed log of their home, workplace, and frequent hangouts.
To turn this off, open your iPhone settings and navigate to Privacy & Security. Tap on Location Services, scroll all the way to the bottom, and select System Services. From there, find Significant Locations. You will need to use Face ID or your passcode to access this menu. Once inside, simply toggle the switch to the off position. You can also clear your existing history from this screen.
Google Location History (Android)
Android devices use a similar feature to power Google Maps timeline and personalized recommendations. Your phone pings your location to Google even when you are not actively using a navigation app.
To disable this, open your device Settings and tap on Location. Look for Location Services, then tap on Google Location History. Choose your Google account and toggle the setting off. You can also choose the auto-delete option to wipe older data automatically while keeping recent data for apps that might need it.
Precise Location for Non-Essential Apps
Both iOS and Android now allow you to choose whether an app gets your precise location or an approximate one. A navigation or ride-sharing app needs your exact coordinates. A local news app, weather widget, or social media platform only needs your general city or zip code.
Review your app permissions in the Location menus of either operating system. Change non-essential apps from “Precise” to “Approximate.” This simple switch protects your exact physical address while still allowing localized apps to function normally.
Background App Refresh and Data Usage
Apps love to stay active even when you are not looking at them. They constantly pull new data from the internet so that your social media feeds and news articles are perfectly up-to-date the second you open them. This background activity is a major culprit for battery drain.
Background App Refresh (iOS) and Background Data (Android)
Most users do not need their apps updating silently in the background. If you open a social network, waiting one extra second for the feed to refresh is completely manageable, and the battery savings are substantial.
On an iPhone, go to Settings, tap General, and select Background App Refresh. You can turn it off entirely, restrict it to Wi-Fi only to save cellular data, or toggle it off for specific, non-essential apps.
On Android, go to Settings, then Network & Internet, and select Data Saver to restrict background data globally. Alternatively, you can go into Apps, select individual apps, and toggle off “Background data” to stop specific programs from draining your resources.
Wi-Fi Assist and Smart Network Switch
Modern smartphones try to keep you connected to the fastest internet possible. If your Wi-Fi signal drops, the phone automatically switches to your cellular data to prevent a service interruption. On iOS, this is called Wi-Fi Assist. On Android, it is known as Smart Network Switch or Adaptive Wi-Fi.
This feature is notorious for chewing through cellular data plans. If your bedroom has a weak Wi-Fi signal, your phone might secretly use your mobile data all night while you stream videos, leading to a massive phone bill.
To turn off Wi-Fi Assist on an iPhone, go to Settings, select Cellular, and scroll all the way to the absolute bottom of the app list to find the toggle. On Android, open your Wi-Fi settings, tap Network Preferences or Advanced, and disable the option to auto-switch to mobile data.
Targeted Advertising and Tracking
Your smartphone acts as a highly effective advertising identifier. Advertisers track your app usage, search queries, and browsing habits to serve you highly specific commercials.
Personalized Ads
Both Apple and Google use your data to serve targeted ads within their respective ecosystems (like the App Store or Google Discover feed). Turning this off does not mean you will see fewer ads, but it does mean your data is no longer being categorized and packaged to target you.
For iOS users, go to Settings, tap Privacy & Security, scroll down to Apple Advertising, and toggle off Personalized Ads.
For Android users, go to Settings, select Privacy, and tap on Ads. Tap “Delete advertising ID” or “Opt out of Ads Personalization” depending on your specific Android version.
App Tracking Transparency
Third-party apps also try to track you across other apps and websites. Apple introduced a feature that forces apps to ask for permission before doing this. If you are tired of getting those pop-ups and want to blanket-deny all tracking requests, go to Settings, Privacy & Security, and select Tracking. Toggle off “Allow Apps to Request to Track.” Any new app you download will automatically be denied tracking permissions.
Unnecessary System Services
Manufacturers constantly collect diagnostic data to see how their devices are performing. They frame this as a way to improve future products, which is technically true, but your device is doing the heavy lifting by sending error logs and usage statistics in the background.
Analytics and Data Sharing
There is no reason your phone needs to waste battery power sending daily diagnostic reports to corporate headquarters.
On an iPhone, go to Settings, Privacy & Security, and tap Analytics & Improvements. Turn off “Share iPhone Analytics.” You can also turn off “Improve Siri & Dictation” while you are there.
On Android, go to Settings, select Privacy, and tap on Usage & Diagnostics. Turn the toggle off to stop your phone from sending backend data to Google.
Auto-Join Wi-Fi and Bluetooth Scanning
Your phone is constantly searching the airwaves for signals. It looks for public Wi-Fi networks to join and Bluetooth devices to pair with. This constant scanning uses battery and presents a security risk, as your phone might connect to a malicious public hotspot without you realizing it.
Ask to Join Networks
You should always have complete control over which wireless networks your phone connects to.
On iOS, go to Settings and tap Wi-Fi. Turn the “Ask to Join Networks” option to “Off” or “Ask.” Also, tap on Auto-Join Hotspot and set it to “Never.”
On Android, go to Settings, Network & Internet, select Internet, and tap Network Preferences. Turn off the “Turn on Wi-Fi automatically” toggle.
Wi-Fi and Bluetooth Scanning (Android)
Android has a specific setting that allows apps and services to scan for Wi-Fi networks and Bluetooth devices at any time, even if you have completely turned off Wi-Fi or Bluetooth. This is primarily used to improve location accuracy, but it is a massive drain on your battery.
Go to Settings, select Location, and tap on Location Services. Turn off both Wi-Fi scanning and Bluetooth scanning. Your GPS will still work perfectly fine without these features running in the background.
Frequently Asked Questions (FAQ)
Will disabling Background App Refresh stop my notifications?
No. Notifications operate on a completely different system. If you turn off Background App Refresh, you will still receive text messages, emails, and alerts instantly. The only difference is that the app will load the actual content (like a new image on a social feed) when you tap the notification and open the app, rather than pre-loading it in the background.
Does turning off Wi-Fi scanning affect my GPS mapping apps?
Turning off Wi-Fi and Bluetooth scanning on Android forces your phone to rely solely on its internal GPS chip for location data. While this might make your location slightly less accurate if you are deep inside a concrete parking garage, it functions flawlessly for normal driving navigation and walking directions, all while saving your battery.
Why do some apps demand precise location to work?
Certain apps are poorly coded or deliberately aggressive with data collection. If a basic calculator or flashlight app demands precise location permissions to function, you should delete it immediately. There are plenty of alternatives in the app stores that respect user privacy.
Take Control of Your Smartphone
Your mobile device is a powerful tool, but it should serve your needs first and foremost. By diving into your menus and disabling these hidden mobile settings, you reclaim control over your data, battery life, and digital footprint. You no longer have to sacrifice privacy for convenience, nor do you have to accept poor battery performance as an inevitable part of owning a modern smartphone.
Take fifteen minutes today to review the permissions on your device. Review the apps you have installed, check what they have access to, and lock down the background processes that are secretly eating away at your resources. Your phone will run faster, last longer, and keep your personal life significantly more private.
