 How to Improve Battery Life on iPhones: Expert Tips

Your iPhone is likely one of your most important tools, serving as a gateway to communication, work, and entertainment. As such, having reliable battery life is crucial. However, even the best iPhone batteries can degrade over time. You might have found yourself constantly reaching for a charger or struggling to make it through the day with just one charge. This article will provide you with expert tips to improve the battery life of your iPhone and help you maintain a more sustainable battery performance over time.

Understanding iPhone Battery Health

To start, it’s important to understand how your iPhone battery works. All iPhones are equipped with lithium-ion batteries, which are known for their fast charging times and long-lasting power. However, these batteries degrade with time and usage, meaning that after a few years, your battery life may significantly reduce. Apple has built-in tools to monitor your battery health, and understanding how to use these tools is the first step toward improving your battery's lifespan.

Battery health can be found in the iPhone settings under “Battery” and then “Battery Health & Charging.” Here, you will see the “Maximum Capacity” percentage, which indicates how much of the original battery capacity remains. When this percentage drops below 80%, it’s a sign that your battery performance is diminishing, and it may be time to consider professional help or a replacement.

Monitor Battery Health Regularly

Checking your battery health on a regular basis is crucial. A battery that’s at or near 100% Maximum Capacity is in prime condition, but as it degrades, you’ll notice that your iPhone will not last as long between charges. To keep an eye on this, navigate to "Settings" > "Battery" > "Battery Health & Charging." By monitoring this over time, you can get an idea of how quickly your battery is deteriorating and act accordingly before it becomes a problem.

Furthermore, the section on "Peak Performance Capability" indicates whether your battery is supporting normal performance. If your iPhone detects that your battery is significantly degraded, it may automatically enable performance management, which reduces processing power to conserve battery life.

Update iOS for Optimized Battery Life

Apple frequently releases iOS updates that not only bring new features but also improve battery management. Keeping your iPhone updated is one of the easiest ways to optimize its performance and battery life. These updates often include bug fixes and optimizations that help apps run more efficiently, leading to less strain on your battery.

To check for updates, go to “Settings” > “General” > “Software Update.” Ensure your iPhone is always running the latest version of iOS. Not only will this improve battery life, but it will also ensure that your phone remains secure and performs optimally.

Limit Background Activity

Your iPhone constantly processes data in the background, which can drain the battery faster than you’d expect. One of the easiest ways to conserve energy is by limiting background activity. You can do this by disabling features like Background App Refresh. This function allows apps to refresh their content even when you're not using them, which, while useful for apps like email or social media, can lead to unnecessary battery drain.

To disable Background App Refresh, go to “Settings” > “General” > “Background App Refresh” and either turn it off completely or select specific apps that don’t need to run in the background.

Adjust Screen Brightness

The brightness of your iPhone’s screen has a significant impact on battery life. Keeping your screen at maximum brightness all the time will cause your battery to drain quickly. Instead, reduce your screen brightness manually or enable Auto-Brightness, which automatically adjusts the brightness based on the lighting conditions around you.

To manually adjust the brightness, swipe down from the top right corner (on iPhone X or later) or swipe up from the bottom (on earlier models) to access the Control Center, where you can lower the brightness slider. For Auto-Brightness, go to “Settings” > “Accessibility” > “Display & Text Size” and enable Auto-Brightness.

Enable Low Power Mode

Low Power Mode is one of the most effective tools for preserving battery life, especially when your battery is running low and you're not near a charger. This mode reduces or disables background activities like mail fetching, background app refresh, and automatic downloads. Additionally, it reduces visual effects and locks the screen quicker.

To activate Low Power Mode, go to “Settings” > “Battery” and toggle the switch to turn it on. You can also add it to your Control Center for quick access by going to “Settings” > “Control Center” and customizing your controls.

Disable Location Services

Location Services can be another major battery drain, as many apps continuously track your location, even when you’re not actively using them. Turning off location services for apps that don’t need it can significantly improve your iPhone’s battery life.

You can manage which apps have access to your location by going to “Settings” > “Privacy & Security” > “Location Services.” Here, you can turn off location services entirely or customize them on an app-by-app basis.

Reduce Push Notifications

Push notifications, especially from apps that frequently update, can also contribute to battery drain. Each time you receive a notification, your screen lights up, and your phone processes the incoming information. By reducing or disabling non-essential notifications, you can conserve a notable amount of battery life.

Go to “Settings” > “Notifications” to manage which apps can send you notifications. Prioritize only those that are necessary, such as messaging apps or important work-related notifications.

Turn Off Unused Connectivity

If you’re not using Wi-Fi, Bluetooth, or AirDrop, turning them off can help conserve battery. These services constantly search for connections in the background, which can drain your battery over time. For example, if you’re traveling or out of range of a Wi-Fi network, it’s better to turn off Wi-Fi to prevent your phone from constantly searching for available networks.

You can easily toggle these settings from the Control Center or by going to “Settings” and turning off Wi-Fi, Bluetooth, and AirDrop when they’re not in use.

Optimize App Usage

Not all apps are created equal when it comes to battery usage. Some apps, particularly games or apps that require frequent internet access, can significantly drain your battery. Identifying and managing these apps can make a big difference in improving battery life.

To see which apps are consuming the most battery, go to “Settings” > “Battery.” Here, you can view battery usage by app over the last 24 hours or 10 days. If you notice certain apps using an excessive amount of power, consider limiting your use of them or finding alternatives.

Utilize Dark Mode

For iPhones with OLED displays (iPhone X and later models), enabling Dark Mode can extend your battery life. OLED screens can turn off pixels when displaying black, which reduces the overall power consumption.

To enable Dark Mode, go to “Settings” > “Display & Brightness” and choose the “Dark” option. Alternatively, you can schedule Dark Mode to turn on automatically at sunset or create a custom schedule.

Adjust Auto-Lock Settings

The Auto-Lock setting determines how long your iPhone screen stays on after you stop using it. Reducing this time can save battery, especially if you tend to forget to lock your screen manually.

To adjust Auto-Lock settings, go to “Settings” > “Display & Brightness” > “Auto-Lock” and select a shorter duration, like 30 seconds or 1 minute.

Use Airplane Mode in Low Signal Areas

One often overlooked way to conserve battery life is to enable Airplane Mode when you're in areas with low or no cellular signal. When your iPhone is in an area with weak cellular reception, it works harder to maintain a connection to a network, which drains the battery more quickly. In such cases, turning on Airplane Mode can prevent the device from using excess power to search for a signal.

You can activate Airplane Mode by swiping down from the top right corner to open the Control Center and tapping the airplane icon. Alternatively, go to "Settings" and toggle on Airplane Mode. Keep in mind that this disables all wireless communication, including calls, texts, and mobile data, but Wi-Fi and Bluetooth can still be enabled manually while in Airplane Mode.

Disable Background App Refresh

Background App Refresh is a feature that allows apps to update their content in the background, even when you’re not using them. While this feature can be convenient for keeping apps like social media and news updated, it can also consume a significant amount of battery. Disabling this feature, especially for apps that don't need to be constantly refreshed, can help extend your battery life.

To turn off Background App Refresh, go to "Settings" > "General" > "Background App Refresh" and either select "Off" or limit it to Wi-Fi only. You can also manage which specific apps are allowed to refresh in the background.

Manage Widgets and Live Wallpapers

While widgets and live wallpapers can make your iPhone more aesthetically pleasing and provide at-a-glance information, they also contribute to battery drain. Widgets continuously pull data in the background to stay updated, and live wallpapers require more processing power due to their animations.

Minimizing the number of active widgets and using static wallpapers instead of live ones can help conserve battery life. To remove widgets, swipe right on your home screen to access the widget panel, scroll to the bottom, and tap "Edit." From there, you can remove any widgets you don't need.

Optimize Charging Habits

Your charging habits can have a significant impact on your iPhone's long-term battery health. Lithium-ion batteries, like the ones in iPhones, don’t need to be fully discharged before charging. In fact, frequent full discharges can wear out the battery faster. Instead, try to keep your battery level between 20% and 80% for optimal health.

Additionally, avoid leaving your iPhone plugged in for long periods after it has reached 100%, as this can generate heat and stress the battery. Apple has introduced "Optimized Battery Charging," which learns your daily charging routine and slows down the charging process once your iPhone reaches 80%, completing the charge just before you typically unplug it. This can help reduce wear on the battery over time.

You can enable Optimized Battery Charging by going to "Settings" > "Battery" > "Battery Health & Charging" and turning on the feature.

Use MFi-Certified Accessories

Using third-party chargers and cables that are not MFi (Made for iPhone) certified can damage your iPhone’s battery and overall performance. These uncertified accessories often don’t meet Apple's safety standards, leading to issues like overheating, inconsistent charging speeds, and reduced battery life.

Always use Apple-certified chargers and accessories to ensure safe and efficient charging. You can recognize MFi-certified products by the "Made for iPhone" label on the packaging. This certification guarantees that the accessories meet Apple’s performance standards.

Keep Your iPhone Cool

Your iPhone’s battery life and performance are greatly affected by temperature. Extreme heat or cold can significantly degrade your battery’s health. If your iPhone gets too hot, it may automatically limit performance or, in extreme cases, shut down until it cools down.

To avoid overheating, don’t leave your iPhone in direct sunlight or in hot environments like a car during summer. Additionally, avoid charging your phone under a pillow or blanket, as these can trap heat. If you notice your phone becoming unusually warm, remove it from its case to allow heat to dissipate more easily.

Cold temperatures can also affect your battery temporarily, causing it to drain more quickly. However, once your phone returns to a normal temperature range, battery performance should stabilize.

Turn Off Automatic Downloads and Updates

By default, your iPhone is set to automatically download app updates, iOS updates, and content from iTunes and the App Store. While convenient, this can cause your battery to drain faster, especially if your device is downloading large files in the background.

To turn off automatic downloads, go to "Settings" > "App Store" and toggle off "App Updates" and "Automatic Downloads." You can manually update apps and software when it's convenient for you, allowing you to better control battery consumption.

Restart Your iPhone Regularly

Restarting your iPhone regularly helps clear out temporary files and memory, ensuring that your device runs efficiently. A reboot can also stop background processes that may be running unnecessarily, which can drain your battery.

It’s a good idea to restart your iPhone every few days or at least once a week to help maintain optimal battery performance. To restart your iPhone, press and hold the power button (and the volume up button if you have an iPhone X or later) until the slider appears. Then, slide to power off and wait a few seconds before turning your device back on.

Avoid Battery-Draining Habits

Certain habits can have a lasting impact on your iPhone's battery health. For example, frequently allowing your battery to drain completely before charging or keeping your phone plugged in for long periods can shorten the battery's lifespan. Also, exposing your phone to extreme temperatures, as mentioned earlier, can cause both short-term and long-term damage to the battery.

To prolong your battery's life, try to avoid these habits. Aim to charge your phone when it reaches about 20% and unplug it once it reaches around 80% to 90%. Also, consider using the "Optimized Battery Charging" feature to help reduce battery wear over time.

Calibrate Your Battery

Over time, the accuracy of your iPhone’s battery percentage indicator may become less reliable. Calibrating your battery can help restore the accuracy of the battery reading. This involves fully charging your phone to 100% and then using it until the battery completely drains and the phone shuts down. Once this happens, recharge your phone back to 100% without interruption.

You don’t need to do this often—calibrating your battery once every three to four months is sufficient for maintaining accurate battery readings.
