Apple has introduced a groundbreaking device: the iPhone Air, which reimagines the classic iPhone by reducing its internal components to achieve a feather-light profile, measuring merely 0.22 inches thick. Incredibly, the company claims this model offers up to 27 hours of video playback—only three hours shy of the iPhone 17’s estimated performance.
Nevertheless, skepticism abounds. A quick glance at the tech community, alongside information sourced from different smartphone reviews, shows that many models rarely fulfill their advertised battery life. These figures typically stem from controlled settings laden with stipulations. There’s indeed a chance the iPhone Air could face notable battery limitations when stacked against other recent releases, a detail I aim to explore once the device is in my hands. That said, holding the iPhone Air evokes a delightful sensation—it’s akin to gripping a credit card capable of making phone calls.
For those willing to compromise somewhat on battery life or camera features in exchange for an iPhone Air, implementing certain settings can help extend battery functionality.
Activating Low Power Mode

One of the simplest methods to enhance battery longevity on an iPhone is to enable Low Power Mode. Achieving this is easy: swipe down from the upper right corner of your Home Screen and tap the battery icon in the controls (or navigate to Settings > Battery > Power Mode and toggle on Low Power Mode).
This mode optimizes battery life but does come with performance trade-offs. Expect diminished background activities, decreased screen brightness and refresh rates, and limited features like 5G and iCloud syncing. Specific animations may be disabled, and your device may automatically lock after 30 seconds of inactivity. Though it may not be ideal for regular use, it can genuinely help in urgent situations.
Utilizing Adaptive Power Mode
Adaptive Power Mode functions similarly to, yet is less severe than, Low Power Mode. Access this feature in the same menu as Low Power Mode, located atSettings > Battery > Power Mode, but it requires an iPhone 15 Pro or later, along with iOS 26.
When activated, this mode leverages Apple’s intelligence to dynamically adjust the device’s performance. It works by analyzing your usage patterns to forecast when you’ll require additional battery life. It might then pause background app refreshes, lower the screen brightness by 3%, or make other performance adjustments. This feature aims to be set and forgotten, differing from Low Power Mode which is better activated only out of necessity. Interestingly, when your battery dips below 20%, Adaptive Power Mode will automatically switch on Low Power Mode.
Do keep in mind that Adaptive Power Mode relies on a learning period of seven days to understand your charging habits, so it’s best to enable it in advance of needing it.
Dimming Your Brightness

If Apple’s automatic power saving features don’t give you enough control, consider manually adjusting your brightness. Keeping the screen at maximum brightness isn’t just uncomfortable; it also hastens battery depletion. Aim to set it to an appropriate level for your current surroundings.
The quickest method is to swipe down from the top right corner of your Home Screen, adjusting the brightness slider featuring a sun icon. Alternatively, for those who prefer settings, go to Settings > Display & Brightness and adjust the slider accordingly.
For those who find manual adjustments cumbersome, enabling Auto-Brightness can be a smart solution. Activate this option via Settings > Accessibility > Display & Text Size > Auto-Brightness. This feature will automatically adapt brightness based on surrounding light conditions—providing less direct control but enhancing convenience.
Reducing Auto-Lock Duration

Within Settings > Display & Brightness, you’ll discover the Auto-Lock feature, which logs you out of your device after a specified inactivity duration. Although a five-minute lock is suitable for detailed reading or following recipes, it does expedite battery drain.
To enhance battery life, consider reducing this timer to thirty seconds or one minute. While this may require more frequent interactions, it will prevent unnecessary power loss if you inadvertently leave your phone unlocked. Rest assured, even with the tightest settings, your screen will remain unlocked during video playback or gaming.
Disabling Always-On Display

The always-on display feature introduced with the iPhone 14 Pro is a standout, allowing for effortless access to notifications and time. However, it does consume battery power, even at a minimal refresh rate of 1Hz.
To disable it, navigate back to Settings > Display & Brightness, and turn off Always On Display. For a less drastic measure, uncheck Show Wallpaper at the top of the menu. This adjustment retains the always-on functionality while displaying just the clock and widgets in black, conserving battery life.
Activating Dark Mode

For an additional boost in battery life, consider opting for Dark Mode through Settings > Display & Brightness. Selecting this option is beneficial because the iPhone utilizes an OLED screen, enabling each pixel to light independently. When showcasing black, the pixel remains off, conserving energy.
Though not universally supported across all applications, it will have a positive impact on battery performance in compatible apps by altering the background to black.
Controlling Data Usage

Utilizing a cellular network tends to consume more battery than accessing Wi-Fi, as a stronger signal is required for longer distances. Therefore, being judicious about data use is essential for conserving battery life on your iPhone.
To simplify this, swiftly disable data by swiping down from your Home Screen, tapping the small green data icon next to the Bluetooth indicator in the corner. While this eliminates data access entirely, it may not be the best strategy for daily use, as it applies to all apps.
For more nuanced control over data usage, navigate to Settings > Cellular. Here, users can toggle options that dictate how their iPhones utilize data.
Disabling Wi-Fi Assist, for instance, prevents the device from utilizing cellular data to enhance a sluggish Wi-Fi connection. This aligns well with the intent to minimize data consumption.
Furthermore, individuals may consider disabling iCloud Drive and iCloud Backup, which use cellular networks to sync and back up files when Wi-Fi is unavailable.
Above these toggles, you can also review and manage which apps are using the most data; limiting their access is a practical approach to cutting down on unnecessary data consumption.
Lastly, activating Wi-Fi Calling enables phone calls over internet connection while on Wi-Fi, preserving cellular data. This can be done by heading to the Settings menu and then navigating to Apps > Phone. Scroll to Calls and ensure Wi-Fi Calling is enabled. You might wish to uncheck Cellular Data in the Allow Phone to Access section, although doing so will prevent calls unless connected to Wi-Fi.
Controlling Background App Refresh

Just because you have exited an application doesn’t mean it’s ceased functioning. Many apps continue to refresh in the background, updating their content and consuming battery power. Here’s how to gain control over this:
Access Settings > General > Background App Refresh to manage how apps refresh while in the background. You’ll find options to disable this feature entirely, keep it activated at all times, or limit it to Wi-Fi connectivity. Setting it to Off will maximize battery efficiency, while Wi-Fi ensures data conservation.
If you keep the feature enabled, you can scroll through your app list and determine which ones may continue to refresh unnecessarily, thereby limiting their background activity without disabling the feature across the board.
Investing in an External Battery Pack

For a more straightforward solution, purchasing an external battery pack could be your best option. The iPhone Air operates seamlessly with any external charging options compatible with previous models. Despite its compactness, it attaches firmly to appropriate accessories via MagSafe. Although suggesting the purchase of additional equipment may feel excessive, Apple certainly promotes this solution. They have even unveiled a MagSafe battery specifically tailored for the iPhone Air, which Apple claims will provide an extra “65 percent charge” while maintaining a slim design.
This accessory retails for $100; its worth will hinge on individual priorities. While the allure of a lightweight design is appealing, the need for an external battery may still arise during particular situations. However, it’s crucial to note that this battery is slightly taller, making it incompatible with both the iPhone 17 and iPhone 17 Pro when placed vertically.
