Ultimate Guide to Maximizing iPhone Battery Life: Top Tips & Tricks

Maximizing iPhone Battery Life


With all the data and media-centered tasks on our smartphones today, battery consumption has become a significant concern for iPhone users. Many find themselves worrying about their phone’s drain rate and looking for ways to make the battery last longer. This guide provides essential tips and tricks for maximizing iPhone battery life. It will enable you to get the most out of your device and reduce the frequency of recharges.

Manage Your Screen Brightness

The iPhone’s dazzling, high-resolution Retina display is beautiful but consumes a substantial amount of power. Your screen brightness is a significant contributor to battery drain. You can control it in two key ways. Firstly, you can adjust your iPhone’s brightness manually by navigating to your settings, then under “Display & Brightness,” lower the brightness slider to a comfortable level.

The second approach is to use your iPhone’s auto-brightness feature. This intelligent setting automatically adjusts your screen’s brightness depending on your environment. For example, it decreases brightness in a dark room and increases it when you are in the sun. To check if it’s enabled, follow the same path as above then ensure the auto-brightness feature is turned on.

Lastly, consider reducing the sleep-wake button timeout so that your screen can turn off when it’s not being used. Combined, these actions will go a long way in maximising iPhone battery life.

Limit Background App Refresh

Some apps run even when you are not actively using them, leading to significant battery drain. Background App Refresh is a feature that allows apps to update content when on Wi-Fi or mobile data. While it can be beneficial, it also consumes battery life heavily.

Start by identifying apps that don’t need to refresh in the background and disable this feature for those apps. You can do this by going to “Settings > General > Background App Refresh”, and toggle off apps you deem unimportant. Remember to leave it on for the apps you frequently use and need updates for.

Additionally, consider closing apps that aren’t in use. Although counter-arguments claim that apps in the background aren’t significant battery drain sources, it’s still a good practise, especially for power-hungry apps like games or high-processing apps.

Optimize Settings for Battery Lifespan

iOS has several features designed specifically for maximizing iPhone battery life. The first of these is the “Battery saving mode,” which reduces background activity and optimizes performance for power efficiency. This feature can be turned on manually from the control center or set to activate automatically at a specific battery level.

Another beneficial feature is “Optimized Battery Charging,” designed to reduce battery aging. It learns from your daily charging routine and slows down battery charging when it predicts you’ll be plugged in for an extended period, like at night. To activate this, navigate to “Settings > Battery > Battery Health > Optimized Battery Charging” and turn it on.

Monitoring apps with high power consumption can also help maximize the battery life. Under “Settings > Battery”, you can see a list of apps and the percentage of battery they’ve used in the last 24 hours or 10 days. This will help you regulate the use of high-power apps or find replacements that consume less power.

Update iOS Regularly

Apple consistently improves battery life in each iOS update by refining system processes and optimizing performance. Therefore, keeping your iPhone updated is a critical step in maximizing battery life.

To check for updates, navigate to “Settings > General > Software Update.” If an update is available, take the necessary steps to install it. However, make sure your device is connected to a power source before beginning the update process.

Notably, installing new updates immediately after release can come with bugs that end up causing more battery drain. Therefore, it is crucial to read reviews and ensure that new updates won’t affect your device negatively.

Reset Settings Or Restore Your iPhone

If you’ve tried everything and your iPhone battery is still draining fast, consider resetting all settings or restoring your iPhone as a final resort. Resetting all settings can eliminate any process that could be unnecessarily draining your battery. To do this, go to “Settings > General > Reset > Reset All Settings.”

A restore is a more comprehensive option that eliminates hardware problems that may be causing battery drain. First, back up all your data to iCloud or your computer. Then go to “Settings > General > Reset > Erase All Content and Settings.” Note that this should only be considered as a last resort after you’ve tried all other options, as it deletes everything on your device.


Maximizing iPhone battery life is achievable by adopting simple habits, such as managing screen brightness, limiting background app refresh, and optimizing settings for battery lifespan. Regular updates and consideration of last resort methods can also help. Remember, these changes will not affect the performance of your device but will instead make your iPhone more energy-efficient and extend its useful life. Hopefully, this guide helps you get the most out of your iPhone’s battery and ensures that power is available when you need it most.
