Turn on Low Power Mode to cut background activity

Low Power Mode is the fastest way to extend your iPhone's battery life. It reduces performance, limits background app refresh, and dims the display slightly — but your phone still works normally for calls, texts, and most apps. You can turn it on manually whenever the battery drops to 20%, or set it to turn on automatically at that threshold.

To enable Low Power Mode, open Settings, tap Battery, then toggle on Low Power Mode. On newer iPhones with Dynamic Island, swipe down from the top-right corner and long-press the battery icon to access it faster. Low Power Mode typically extends your battery by 1 to 3 hours depending on your usage.

Key Takeaways

  • Low Power Mode reduces background activity and can extend battery life by 1 to 3 hours without affecting basic phone functions.
  • Turning off location services, Bluetooth, and Wi-Fi when you are not using them prevents constant battery drain from background scanning.
  • Reducing screen brightness and enabling auto-brightness saves more battery than any other single setting change.
  • Apps running in the background consume power even when you are not using them — check Battery settings to see which apps drain the most and close them when idle.
  • Disabling push notifications and setting mail to fetch manually instead of pushing new messages saves battery throughout the day.

Lower your screen brightness and enable auto-brightness

Your display uses more battery than any other component on your iPhone. Reducing brightness to 30 to 40% during normal use, or enabling auto-brightness to let the phone adjust based on ambient light, cuts display power consumption significantly. Auto-brightness is especially useful because it keeps the screen dim indoors and bright enough outdoors without you having to adjust manually.

To enable auto-brightness, go to Settings, tap Display & Brightness, then toggle on Auto-Brightness. If you prefer manual control, drag the brightness slider down to a comfortable level — even a 20% reduction in brightness extends battery life noticeably. Avoid maximum brightness unless you are outdoors in direct sunlight.

Turn off location services and background app refresh

Location services and background app refresh drain battery by running continuously in the background. Location services use GPS, Bluetooth, and Wi-Fi to pinpoint your location even when you are not actively using an app. Background app refresh lets apps update their content without you opening them — useful for weather and news apps, but unnecessary for most others.

To disable background app refresh, go to Settings, tap General, then Background App Refresh, and toggle it off. For location services, go to Settings, tap Privacy & Security, then Location Services. You can turn it off entirely or allow it only for specific apps like Maps or weather. Disable location for apps that do not need it — social media, games, and shopping apps rarely need your location.

Check which apps consume the most battery

Some apps drain battery far faster than others. Your iPhone tracks which apps use the most power, and you can see the list in real time. Open Settings, tap Battery, then scroll down to see battery usage by app over the last 24 hours or last 10 days. Apps using more than 10% of your battery in a day are worth investigating.

If an app uses excessive battery, you have three options: close it when you are not actively using it, uninstall it, or check its settings for background activity. For example, a navigation app running in the background will drain battery quickly — close it after you reach your destination. Social media apps often refresh feeds constantly; open their settings and disable background refresh for that app specifically.

Disable push notifications and switch to manual mail fetch

Push notifications wake your phone's screen and processor every time an app sends a message. Manual fetch means your phone checks for new email only when you open the Mail app, rather than checking constantly. Switching from push to manual or fetch-on-demand saves battery throughout the day.

To change notification settings, go to Settings, tap Notifications, then review which apps have permission to send notifications. Disable notifications for apps that do not need them — games, shopping apps, and social media are common culprits. For email, go to Settings, tap Mail, then Accounts, select your account, and change Fetch New Data from Push to Fetch or Manual. Set fetch to every 30 minutes or longer if you do not need when ready email updates.

Turn off Bluetooth and Wi-Fi when not in use

Bluetooth and Wi-Fi constantly scan for devices and networks even when you are not connected to anything. Turning them off when you leave home or do not need them prevents this background drain. You do not need to disable them entirely — just switch them off when you know you will not use them for several hours.

Swipe down from the top-right corner (or up from the bottom on older iPhones) to open Control Center. Tap the Bluetooth icon to disable it, and tap the Wi-Fi icon to disconnect. If you use Bluetooth headphones or a smartwatch regularly, keep Bluetooth on but disable Wi-Fi when you are away from home networks you use. This balance keeps your most-used features active while cutting unnecessary background scanning.

Disable visual effects and reduce motion

Animated transitions, parallax effects, and motion graphics consume processor power and battery. Disabling these visual effects — especially parallax and reduce motion — lightens the load on your phone's processor. The difference is small compared to screen brightness or background apps, but it adds up over a full day.

Go to Settings, tap Accessibility, then Display & Text Size. Toggle on Reduce Motion to disable parallax and animated transitions. You can also go to Settings, tap Display & Brightness, and toggle off Dynamic Island or live widgets if your iPhone supports them. These changes make your phone feel slightly less smooth, but the battery savings are real and the interface remains fully functional.

Frequently Asked Questions

Does Low Power Mode slow down my iPhone?

Yes, slightly. Low Power Mode reduces processor speed and limits background activity, so apps may open a fraction slower and some features like automatic downloads pause. For most daily tasks — texting, calling, browsing, email — you will not notice the difference. If you need full performance for gaming or video editing, turn Low Power Mode off temporarily.

Will turning off Bluetooth and Wi-Fi hurt my phone's ability to work?

No. Turning off Bluetooth and Wi-Fi only stops your phone from scanning for and connecting to devices and networks. Your phone still receives cellular data and works normally. You can turn them back on whenever you need them — it takes two seconds from Control Center.

Can I use my iPhone normally while in Low Power Mode?

Yes. Low Power Mode does not restrict calls, texts, or app use. It only reduces background activity and processor speed. You can browse the web, use social media, take photos, and navigate normally. The only noticeable change is slightly slower performance and a dimmer screen.

What is the difference between fetch and push for email?

Push means your mail server sends new messages to your phone when ready, waking it up each time. Fetch means your phone checks the server at set intervals — every 15, 30, or 60 minutes. Manual means your phone only checks when you open the Mail app. Manual and longer fetch intervals save the most battery.

Does closing apps in the background actually save battery?

Closing apps manually does not save much battery because iOS already suspends apps you are not using. However, disabling background app refresh for specific apps in Settings does save battery. Focus on turning off background refresh rather than constantly closing apps.
