1- Optimize Screen Brightness:
Lower your screen brightness or enable auto-brightness to adjust it based on your surroundings.
2- Use Wi-Fi Over Cellular Data:
Whenever possible, connect to Wi-Fi networks instead of relying on cellular data, as Wi-Fi is generally more power-efficient.
3- Turn Off Background App Refresh:
Disable or limit background app refresh for apps that don't need to update in the background constantly.
4- Manage Location Services:
Go to Settings > Privacy > Location Services and choose which apps should have access to your location. Use "While Using" or "Ask Next Time" for better control.
5- Disable Push Email:
Change your email settings to fetch new messages at intervals rather than using push email, which constantly checks for new messages.
6- Update Apps and iOS:
Keep your apps and iOS up to date as new versions often include performance and battery optimizations.
7- Use Low Power Mode:
Enable Low Power Mode in the Battery section of your iPhone's settings when your battery is running low. This mode reduces background processes and adjusts settings to conserve power.
8- Reduce Background App Activity:
Close apps running in the background that you're not actively using. Double-click the home button (or swipe up from the bottom on newer models) and swipe away apps you want to close.
9- Manage Notifications:
Disable notifications for apps that aren't essential. Go to Settings > Notifications to customize your notification preferences.
10- Limit Widgets and Dynamic Wallpapers:
Remove unnecessary widgets from your Today View and avoid using dynamic wallpapers, as they can drain battery.
11- Use Airplane Mode in Low Signal Areas:
When in areas with poor cellular reception, switch to Airplane Mode to prevent your phone from constantly searching for a signal.
12- Reduce Motion and Transparency:
In Accessibility settings, reduce motion and transparency effects, which can help improve battery life.
13- Keep Your Phone at Optimal Temperatures:
Extreme heat or cold can affect battery performance. Try to keep your iPhone within the recommended temperature range.
14- Use Battery Health Features:
Check your battery's health in Settings > Battery > Battery Health. If the capacity is significantly reduced, consider replacing the battery.
15- Limit Background Refresh for Apps:
In Settings > General > Background App Refresh, you can control which apps are allowed to refresh their content in the background. Disable this feature for apps that don't need it.
Remember that the effectiveness of these tips can vary depending on your usage and the model of your iPhone. Experiment with these suggestions to find the combination that works best for your specific needs while maximizing your battery life. This is How to Have a Longer Battery Life on iPhones
