10 iPhone battery life tips — from iOS 26 Adaptive Power to turning off 5G

Modern iPhones come with large batteries, but on days when you are away from a charger for extended periods, even the best battery can struggle. We have compiled 10 practical tips to help you reduce power drain and make your iPhone last longer.

**1. Turn on Adaptive Power.** This is the most effective way to save battery on Apple Intelligence iPhones running iOS 26. The feature uses on-device machine learning to analyze your daily usage patterns and predict when you might need extra power. It automatically lowers screen brightness, adjusts processor performance, and limits background activity. It also activates Low Power Mode when the battery drops to 20 percent. On iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max, Adaptive Power is enabled by default upon first setup, but you can verify it in Settings Battery.

**2. Use Low Power Mode manually.** You can activate it from Control Center or via Settings Battery. This mode pauses background tasks such as email fetching, automatic downloads, Siri suggestions, and visual effects like reduced motion. Phone calls, messaging, and core apps remain functional. It is ideal for the last few hours of the day.

**3. Disable 5G.** If 5G coverage in your area is weak or inconsistent, your iPhone constantly switches between 5G and 4G LTE, which consumes significant power. Go to Settings Cellular Voice & Data and select "4G" instead of "5G Auto" or "5G On". This will reduce data speeds but can extend battery life by up to two hours in poor coverage zones.

**4. Reduce screen brightness.** The display is the largest power consumer on any iPhone. Lower the brightness slider in Control Center manually, or enable auto-brightness in Settings Accessibility Display & Text Size. Auto-brightness adjusts the screen based on ambient light, but it may still keep it brighter than necessary in dark environments.

**5. Limit background app refresh.** Many apps refresh content in the background even when you are not using them. Go to Settings General Background App Refresh and disable it for apps that do not need constant updates, such as social media, news, or weather apps. Keep it enabled only for messaging or navigation apps that require real-time data.

**6. Turn off Push email.** Instead of having the server push new emails to your phone instantly, switch to manual fetch or set a longer interval. In Settings Mail Accounts Fetch New Data, disable "Push" and choose "Manual" or "Every Hour". This reduces network activity and saves battery.

**7. Disable Always-On Display.** On iPhone 14 Pro and newer models, the Always-On Display keeps the screen dimly lit and updates the time, widgets, and wallpaper. While it uses minimal power, turning it off can still save a few percent of battery over a full day. Go to Settings Display & Brightness Always-On Display and toggle it off.

**8. Remove unnecessary widgets.** Widgets on the home screen, especially those for weather, calendar, or stocks, refresh periodically in the background. To remove them, press and hold the home screen, tap the minus icon on widgets, and delete those you rarely use. This reduces background activity.

**9. Turn off Bluetooth and Wi-Fi when not in use.** Even when not connected, these radios scan for devices and networks, draining battery. Use Control Center to toggle them off when you are not using wireless headphones, a smartwatch, or a Wi-Fi network. Note that disabling them from Control Center only disconnects until the next day; use Settings to fully disable them.

**10. Calibrate the battery.** If your iPhone battery percentage jumps or drops unexpectedly, calibration may help. Fully drain the iPhone until it turns off, then charge it uninterrupted to 100 percent. This helps the battery management system recalculate the exact capacity. It is recommended to do this once every few months.

Following these tips can significantly extend your iPhone's runtime on a single charge, especially during long days away from a power outlet.
