How to Maintain Battery Health on iPhone 14 Pro Max

To maintain battery health on your iPhone 14 Pro Max, adopt a few simple yet effective techniques. Firstly, use original or Apple-certified accessories for charging to ensure a safe and efficient process. Embrace the 40-80 rule by charging your device when it drops to 40% and unplugging it at 80%, though it’s not necessary to stick to this strictly. Avoid overcharging by disconnecting your phone after reaching a sufficient charge, and resist the temptation to leave it plugged in overnight. Additionally, disable power-consuming features like the Always-On Display and ProMotion when not in use. These small adjustments, coupled with mindful charging habits, contribute to the longevity and optimal performance of your iPhone 14 Pro Max battery.

Tips to Maintain Battery Health on iPhone 14 Pro Max

Use Original or Apple Certified Accessories

Maintaining battery health starts with the basics. Always use original or Apple-certified accessories for charging your iPhone 14 Pro Max. Genuine accessories are designed to meet Apple’s strict standards, ensuring a safe and efficient charging process. Non-certified accessories may not provide the necessary voltage and could harm the battery over time.

Use the 40-80 Rule 

One widely recognized practice for preserving iPhone battery health is the 40-80 rule. This means keeping your battery level between 40% and 80%. Charging your phone when it drops to 40% and unplugging it when it reaches 80% can help maintain the battery health of your iPhone 14 Pro Max

Don’t Overcharge Your Phone

While it’s tempting to leave your phone plugged in overnight for a full charge, this habit can greatly affect your battery health. The iPhone 14 Pro Max, like its ancestors, is equipped with optimized charging features. It learns your daily charging patterns and slows down the battery aging process by avoiding overcharging. 

Disable the Always-On Display

The Always-On Display is a nifty feature that provides at-a-glance information on your locked screen. However, it comes at a cost – increased power consumption. Disabling the Always-On Display when it’s not needed can significantly contribute to maintaining your iPhone 14 Pro Max’s battery life. To do so, go to Settings > Display & Brightness and toggle off the “Always On” option.

Disable ProMotion

The ProMotion technology on the iPhone 14 Pro Max allows for a smoother and more responsive display by dynamically adjusting the refresh rate. While this feature enhances user experience, it also consumes more power. If you’re looking to maintain battery life on your iPhone 14 Pro Max, consider disabling ProMotion by going to Settings > Accessibility. Select “Motion” under the “Vision” category and toggle off the “Auto-Adjust Display Refresh Rate” option.

Disable Keyboard Haptics

The haptic feedback when typing can be satisfying, but it utilizes the Taptic Engine, contributing to battery drain. Disabling keyboard haptics can be a small sacrifice for those seeking to maximize battery life without compromising on essential functionalities. To disable it, go to Settings > Sounds & Haptics and Turn off “Keyboard Haptics.”

Avoid Charging and Using Your Phone Simultaneously

Simultaneous charging and heavy usage generate more heat, which is harmful to battery health. Whenever possible, charge your iPhone 14 Pro Max when it’s not in use. This simple adjustment can contribute significantly to the overall well-being of your device’s battery.


In conclusion, maintaining battery health on your iPhone 14 Pro Max involves a combination of mindful charging habits and making strategic adjustments to certain features. By using certified accessories, following the 40-80 rule, avoiding overcharging, and disabling power-hungry features when unnecessary, you can ensure that your iPhone’s battery continues to perform optimally throughout its lifecycle without getting costly phone repair services.
