12 iPhone 17 Settings to Change Right After Setup for Better Battery, Privacy, and Performance
Introduction
If you just set up an iPhone 17, one of the smartest things you can do next is change a few default settings right away.
Out of the box, iPhone is designed to be easy to use, but the default setup is not always the best balance for battery life, privacy, and everyday performance. Some settings allow extra background activity. Others expose more lock screen information than many people realize. A few are worth changing immediately if you want a cleaner, more efficient setup from day one.
The good news is that you do not need to turn your phone into a stripped-down device to get better results. A small set of practical changes can reduce unnecessary battery drain, limit tracking, tighten security, and make the phone feel more controlled without hurting the overall experience.
Apple’s current support pages confirm that iPhone users can manage charging behavior, Background App Refresh, app tracking, location access, lock screen previews, App Privacy Report, analytics sharing, Stolen Device Protection, and Always-On display settings directly from Settings. For Apple’s official iPhone 17 page, see iPhone 17.
In this guide, you will learn:
Which iPhone 17 settings to change first
How to improve battery life without making the phone annoying to use
Which privacy settings are actually worth turning on or turning off
How to build a better setup for daily use right after setup
Why These Settings Matter
Battery, privacy, and performance issues usually do not come from one dramatic mistake. They come from a collection of small defaults that add up over time.
For example, one app refreshing in the background is not a big deal. Ten apps doing it all day can be. One app with location access may be reasonable. A long list of apps with permanent location access is not. A few lock screen notifications are convenient, but showing message previews and account alerts on a locked phone can expose more information than most people want.
That is why the best setup is not about disabling everything. It is about adjusting the settings that give you the biggest practical gain first.
1. Turn On Optimized Battery Charging
This is one of the first settings worth checking, especially if you charge overnight.
Why it matters:
Apple says Optimized Battery Charging is designed to reduce battery aging
Long periods at a full charge can contribute to long-term battery wear
This setting is one of the easiest ways to protect battery health over time
What to do:
Open Settings
Tap Battery
Tap Charging
Turn on Optimized Battery Charging
Apple’s support page for newer iPhones says that on iPhone 15 and later, charging options are under Settings > Battery > Charging. See Apple’s official guide here: Optimize iPhone battery charging.
2. Learn Your Battery Screen Before Changing Random Things
Many people start changing settings without checking what is actually using battery.
Why it matters:
Your battery screen can show whether the problem is the display, background activity, or one specific app
Guessing often leads people to disable useful features that are not the real issue
Battery data gives you a better starting point than trial and error
What to do:
Open Settings
Tap Battery
Review the daily usage chart and app activity
Apple’s battery support page specifically tells users to check the Daily Usage chart when troubleshooting battery drain. If one app stands out, fix that first. For Apple’s guidance, see If the battery in your iPhone drains too quickly.

3. Limit Background App Refresh
This is one of the most effective battery settings for many users.
Why it matters:
Background App Refresh lets apps update content when you are not actively using them
That can be useful for some apps, but unnecessary for many others
Too much background refresh can waste battery and data
What to do:
Open Settings
Tap General
Tap Background App Refresh
Turn it off for apps that do not need to update constantly
Apple’s support documentation confirms that Background App Refresh is managed in Settings > General > Background App Refresh. You do not need to disable it for everything, but it makes sense to limit it for shopping apps, casual games, and apps you rarely open. See Apple’s support references here: Switch apps on your iPhone.
4. Tighten Location Access
Location is one of the biggest privacy settings to review right after setup.
Why it matters:
Many apps request location even when they do not need constant access
Location use can also affect battery life, especially with Always access
Reducing unnecessary access is one of the cleanest privacy wins on a new phone
What to do:
Open Settings
Tap Privacy & Security
Tap Location Services
Review app permissions one by one
Use While Using the App instead of Always where it makes sense
Apple says you can manage app location permissions in Settings > Privacy & Security > Location Services. For official help, see Turn Location Services and GPS on or off on your iPhone and About privacy and Location Services in iOS.
5. Turn Off App Tracking Requests If You Want a Cleaner Privacy Setup
This is one of the most useful privacy changes for many iPhone users.
Why it matters:
Apps can request permission to track your activity across apps and websites
Many users would rather not deal with repeated tracking prompts
Turning off the request system is a simple way to reduce ad-related tracking permissions
What to do:
Open Settings
Tap Privacy & Security
Tap Tracking
Turn off Allow Apps to Request to Track
Apple’s support page says you can review or change tracking permissions in Settings > Privacy & Security > Tracking, and you can stop all apps from asking to track at the top of that screen. See Apple’s official guide here: Control app tracking permissions on iPhone.

6. Hide Lock Screen Notification Previews
This is one of the best privacy changes you can make in less than a minute.
Why it matters:
Notification previews can expose personal information while your phone is locked
Messages, bank alerts, login codes, and health notifications are often more revealing than people expect
This matters in public, at work, during travel, and even at home
What to do:
Open Settings
Tap Notifications
Tap Show Previews
Select When Unlocked or Never
Apple’s notification settings documentation explains that you can prevent previews from appearing on the Lock Screen by changing Show Previews. See Apple’s official help pages here: Change notification settings on iPhone and Use notifications on your iPhone.
7. Turn On Stolen Device Protection
This is one of the most important security settings to enable on a new iPhone.
Why it matters:
It adds extra security when your iPhone is away from familiar locations
Apple says it can require Face ID or Touch ID for critical actions and add a security delay for sensitive account changes
This is especially valuable if someone ever gets both your iPhone and your passcode
What to do:
Open Settings
Tap Face ID & Passcode
Enter your passcode
Tap Stolen Device Protection
Turn it on
Apple’s support page explains how Stolen Device Protection works and notes that you can also choose Always for stricter protection. See Apple’s official guide here: About Stolen Device Protection for iPhone.
8. Review What Is Allowed on the Lock Screen
Even if your phone is locked, some features may still be accessible.
Why it matters:
Lock Screen access settings can affect convenience and security
You may not want every feature available while the phone is locked
Restricting some access can reduce casual exposure or misuse
What to do:
Open Settings
Tap Face ID & Passcode
Review the options under Allow Access When Locked
Turn off anything you do not want available from the Lock Screen
Apple’s support guide explains that features like Control Center, widgets, and media controls can be available on the Lock Screen, and those options are managed under passcode settings. See Apple’s official documentation here: Turn on Lock Screen features on iPhone.
9. Check App Privacy Report
This setting is one of the most overlooked privacy tools on iPhone.
Why it matters:
It shows how apps use permissions you have granted
It also shows network activity
This can help you identify apps that are doing more than you expected
What to do:
Open Settings
Tap Privacy & Security
Tap App Privacy Report
Review which apps are accessing permissions and network domains
Apple says App Privacy Report shows how apps use granted permissions and their network activity. See Apple’s official pages here: About App Privacy Report and Control access to information in apps on iPhone.
10. Turn Off Analytics Sharing If You Prefer Less Data Sharing
This will not transform your battery life, but it is a clean privacy setting to review after setup.
Why it matters:
Apple lets you choose whether to share analytics and usage information
Some users prefer to limit diagnostic sharing where possible
This is part of a more privacy-conscious setup
What to do:
Open Settings
Tap Privacy & Security
Scroll down to Analytics & Improvements
Review and turn off any sharing options you do not want
Apple’s documentation says analytics and usage data can be managed in Settings > Privacy & Security > Analytics & Improvements. See Apple’s official support pages here: Share analytics, diagnostics, and usage information with Apple and Get information about your iPhone.
11. Decide Whether You Really Want Always-On Display
Always-On display can be useful, but not everyone wants the tradeoff.
Why it matters:
It keeps a dimmed version of the Lock Screen visible
That adds convenience, but some users would rather save battery and reduce what can be seen on the screen
It is worth deciding intentionally instead of leaving the default unchanged
What to do:
Open Settings
Tap Display & Brightness
Tap Always On Display if available
Turn it off, or reduce what appears on it
Apple’s support documentation says Always-On display is on by default on supported models and can be changed in Settings > Display & Brightness. It also notes that you can choose whether wallpaper or notifications appear. See Apple’s official guide here: Keep the iPhone display on longer.
12. Set Up Low Power Mode the Smart Way
Low Power Mode is useful, but it works best as a tool, not as a permanent bandage for a bad setup.
Why it matters:
Apple says Low Power Mode reduces or disables features such as Background App Refresh, some visual effects, and other power-intensive behavior
It is excellent for travel days, heavy-use days, or emergencies
If your battery drain is abnormal all the time, you still need to fix the real cause
What to do:
Open Settings
Tap Battery
Tap Power Mode
Turn on Low Power Mode when needed
Add it to Control Center if you want faster access
Apple’s support pages for current iPhones say Low Power Mode is under Settings > Battery > Power Mode on iPhone 15 and later. See Apple’s official documentation here: Use Low Power Mode to save battery life on your iPhone and If the battery in your iPhone drains too quickly.
Why the Problem May Continue Even After These Changes
If your battery still drains quickly or the phone still feels busy after these changes, the issue may not be your settings alone.
Common reasons include:
A buggy app using too much background power
Poor cellular signal causing the phone to work harder
Heavy camera, gaming, or hotspot use
Cloud syncing and indexing after initial setup
Software settling during the first few days after transfer or restore
If your iPhone also feels warm during setup or restore, that can be temporary. This section would pair well later with an internal article like Why Your iPhone Gets Warm After Setup.
When Not to Overdo It
Not every setting should be pushed to the strictest possible option.
For example:
Do not disable Background App Refresh for apps that genuinely need timely updates
Do not remove location access from apps that depend on it to function properly
Do not hide every notification if that makes the phone less useful for your routine
Do not rely on Low Power Mode as the only solution if one app is clearly draining battery
The goal is a smarter setup, not a frustrating one.
Conclusion
If you want your iPhone 17 to feel better right away, start with the settings that matter most.
Turn on Optimized Battery Charging. Review the Battery screen. Limit Background App Refresh. Tighten location access. Turn off unnecessary tracking requests. Hide notification previews. Enable Stolen Device Protection. Review Lock Screen access. Check App Privacy Report. Turn off analytics sharing if you prefer. Decide whether you want Always-On display. Use Low Power Mode strategically.
Those changes give you a better balance of battery life, privacy, and daily performance without making your phone harder to use.
If you only change a few things today, start with charging settings, Background App Refresh, location permissions, notification previews, and Stolen Device Protection. Those usually give the biggest practical benefit right away.
