How to Extend iPhone Battery Life: Practical Tips for 2026

Battery life is one of the most concerned issues for iPhone users. Many users report that after using their iPhone for a period of time, the battery drains faster and faster, the battery health drops significantly, and even needs to be replaced frequently. In fact, the loss of iPhone battery is not only due to normal use and aging, but also more caused by bad usage habits. In 2026, combined with the battery characteristics of the new iPhone 18 series, we have sorted out 6 practical iPhone battery maintenance tips to help you extend battery life and make your mobile phone battery more durable.

Tip 1: Avoid overcharging and over-discharging. Many users are used to charging their iPhone before going to bed at night and keeping it charged until the morning. This habit of overcharging will accelerate battery loss; at the same time, try to avoid using the battery power to 0% before charging, as over-discharging will seriously damage battery health. Suggestion: Start charging when the power is 20%-30% remaining, and disconnect the power when it is charged to 80%-90%. When charging at night, you can turn on the "Optimized Battery Charging" function (Settings-Battery-Battery Health & Charging, turn on Optimized Battery Charging). This function will intelligently adjust the charging speed to avoid the battery being in a fully charged state for a long time.

Tip 2: Control the charging environment temperature. iPhone batteries are very sensitive to temperature. Too high or too low temperature will accelerate battery loss. Suggestion: Avoid placing the mobile phone in high-temperature environments such as direct sunlight, next to heating, or under quilts when charging, and do not charge it in low-temperature environments (such as outdoors in winter); if the phone gets very hot when in use (such as playing games, shooting videos), stop using it and charge it after the phone cools down.

Tip 3: Reduce the consumption of background apps and useless functions. Many users are used to keeping a large number of apps running in the background. These background apps will continuously consume power and accelerate battery loss. Suggestion: Regularly clean up background apps and turn off unused background app refresh functions (Settings-General-Background App Refresh, select "Off" or "Wi-Fi Only"); at the same time, turn off useless location services, push notifications, dynamic wallpapers and other functions to reduce unnecessary power consumption.

Tip 4: Adjust screen settings reasonably. The screen is one of the fastest power-consuming components of the iPhone. Unreasonable screen settings will greatly increase power consumption. Suggestion: Adjust the screen brightness to a moderate level (no need to be the brightest, just enough), turn on the auto-brightness adjustment function to let the phone automatically adjust the brightness according to the ambient light; turn on the "Auto-Lock" function and set the lock time to 1-2 minutes to avoid the screen being on for a long time and consuming power; for models that support 120Hz refresh rate (such as iPhone 18, 18 Pro series), you can switch to 60Hz refresh rate according to your needs to further save power.

Tip 5: Maintain battery health regularly. In addition to daily usage habits, regular maintenance can also effectively extend battery life. Suggestion: Calibrate the battery once a month (use the power to below 20%, then fully charge to 100% without interruption) to help the phone display battery health more accurately; avoid using unofficial and inferior chargers, which may damage the battery. It is recommended to use Apple's official charger or third-party compliant charger; if the battery health is below 80%, go to Apple's official direct store to replace the battery in time to avoid battery aging affecting the user experience.

Tip 6: Adjust the mode according to the usage scenario. Reasonably adjusting the mobile phone mode in different usage scenarios can also effectively save power. Suggestion: When going out without a power source, turn on Low Power Mode (Settings-Battery-Low Power Mode), which will turn off some non-essential functions and extend battery life; turn on Airplane Mode when not using the phone at night, which can not only save power but also reduce radiation; when not using the phone for a long time (such as a few days), keep the power at around 50% to avoid storing it with too high or too low power, which will damage the battery health.

The above 6 practical tips are fully applicable to both the new iPhone 18 series and the existing old iPhone. Developing good battery usage habits can not only extend battery life but also reduce the trouble of frequent charging, making your iPhone more durable and worry-free.
