Toincrease iPhone battery life, turn on Low Power Mode (Settings > Battery), lower screen brightness and timeout, disable Background App Refresh for non-essential apps, use dark mode, and manage location services. These simple changes often add 20-50% more usage time per charge.
Why iPhone Battery Life Drops and How to Improve It
Even with large batteries in newer iPhones, features like always-on display, high refresh rates, constant notifications, and background processes can cause the battery to drain faster than expected. Many users only get 5-7 hours of screen-on time on a full charge.
The good news is that iOS offers excellent built-in tools to extend battery life significantly. Combining Low Power Mode with smart settings adjustments can easily add 20-50% more usage time without major sacrifices.
This guide walks you through the most effective, safe methods that work on all recent iPhone models. Related: Checkhow to reduce data usage on iPhonefor additional efficiency gains.
Common Causes of Fast iPhone Battery Drain
- High screen brightness and long timeout
- Background App Refresh and notifications
- Location services running constantly
- Always-on display and high refresh rates
Enable Low Power Mode
Low Power Mode is the fastest and most effective single change for extending battery life.
- Go toSettings>Battery.
- Toggle onLow Power Mode.
- Set it to turn on automatically at 20% or 10% if preferred.
It reduces background activity, dims the screen, and limits animations while still letting you use your phone normally.
Optimize Display Settings
The screen is one of the biggest power users. Small tweaks here deliver big savings.
- Lower brightness or enable Auto-Brightness
- Set Auto-Lock to 15-30 seconds
- Enable dark mode (especially helpful on OLED models)
- Reduce motion or set refresh rate to standard when possible
Limit Background App Refresh
Background App Refresh lets apps update in the background and uses significant power.
- Go to Settings > General > Background App Refresh.
- Set it to Wi-Fi or Off for most apps.
Manage Location Services
Location services are convenient but drain battery when used unnecessarily. Review which apps have “Always” access and change to “While Using” or “Never” where possible.
Smart App and Notification Management
Turn off unnecessary notifications and review which apps have permission to run in the background. This prevents constant wake-ups that consume power.
Keep iOS and Apps Updated
Apple regularly improves battery efficiency through iOS updates. Keeping your software and apps current often brings noticeable battery gains.
Daily Habits for Better Battery Health
- Avoid extreme temperatures while charging or using the phone
- Use optimized charging (available on newer models)
- Restart your iPhone weekly
- Monitor battery usage in Settings > Battery
