Extend iPhone Battery: Changing the settings below can significantly increase battery life on your site, but the result will depend on what you’re willing to trade off for performance.
If you prefer not to change many settings (or any at all), another option is to simply get a battery case or portable power bank, or consider replacing your battery or upgrading your iPhone.

1. How do Apps Use iPhone Batteries?
Go to Settings > Battery to check battery usage details. “Last 24 hours” is the default and shows which apps are consuming the most power (including Home and Lock screen and Siri).
Clicking on the “last 10 days” button on the right will give you more detailed information about what has consumed energy.

2. Low Power Mode and Performance Management
The low-power mode is a quick way to extend battery life when needed. The feature works by pausing emails, updating apps in the background, automatic downloads, and more. with just one button. It’s not an everyday feature (hopefully), but it’s handy nonetheless.
You can enable Low Power Mode under Settings > Battery. However, quick access to low-power mode in the control center is useful. Go to Settings > Control Center > Customize controls, then tap the + next to Low Power Mode if it’s not already there.

Another feature similar to automatic low power mode is iOS performance management. If the iPhone’s battery is degraded, the performance will automatically decrease to save battery power and prevent it from shutting down unexpectedly.
You can check if your iPhone is using performance management in Settings > Battery > Battery Health. While you can turn off performance management for iPhones with damaged batteries, be aware that doing so will drain your iPhone’s battery faster. Read more about the feature in Apple’s support documentation here.
Another detail: if you turn off performance management, you can’t re-enable it manually, you have to wait for the iPhone to unexpectedly turn off again, which forces it to turn on again.
3. Auto Lock and Screen Brightness
If you notice that “home and lock screen” battery usage is higher than expected, check these settings.
30-second auto-lock helps save battery power as much as possible. 30 seconds is worth it, especially since most Apple iPhones support restarting to wake. Go to Settings > Display & brightness > Auto-lock. Lowering the screen brightness can also help reduce battery life, but this may come down to personal preference. You can do this in the Control Center (swipe down from the top-right corner) or in Settings > Display & Brightness.
4. Hot and Cold Weather
Apple states that the ideal room temperature for the iPhone and other Apple devices is 62° to 72° F (16° to 22° C). Temperatures above 95°F (35°C) can “permanently damage battery capacity.”
In addition to doing everything you can to protect your iPhone from overheating, it’s a good idea to remove the case if you notice your iPhone getting hot.
5. Background App Refresh
Low Power Mode turns off background app refresh across the board, but you can customize which apps use this feature for a more convenient experience as well as improved battery life. Head to Settings > General > Background App Refresh.
You can also opt to only use background app refresh on Wi-Fi in addition to Wi-Fi and Cellular or turn the feature off totally. However, most users will find leaving Wi-Fi and Cellular on while customizing which apps are used for background app refresh to be the best fit.
Turning off Background App Refresh prevents apps that you’re not actively using from updating (until you open them again).
6. Location Services
Dialing in your location services settings is another way to extend battery life. (It can reduce cellular data use too). Head to Settings > Privacy > Location Services to update the privileges for your apps.
Look out for any apps that ask to Always use your location and switch to While Using, Ask Next Time, or Never.
7. Push and Fetch Extend iPhone Battery
If you choose not to use Low Power Mode, you can manually control Push and Fetch for your email/internet accounts.
Head to Settings > Mail > Accounts > Fetch New Data. One approach is to leave your primary account(s) as push to receive new mail asap and turn less important accounts to fetch every hour or even set them to manual.
Wrap-up on how to Extend iPhone Battery Life
In a pinch, using Low Power Mode and turning down your screen brightness are two of the fastest ways to extend iPhone battery life. But hopefully having a better idea of which apps are zapping your power the most and checking in on locations services will also give you useful tools to conserve power.
And don’t forget, for the best iPhone battery longevity, keep Optimized Battery Charging turned on (and avoid leaving your iPhone at 100% charge as much as possible). You can double-check that in Settings > Battery> Battery Health.
