Your trusty iPhone may not be performing as swiftly as it once did, but fear not! It’s not just your imagination. Studies have shown that older iPhones tend to experience a decline in speed. For those seeking a speedy solution, AnyTimeSoftcare offers eight effective ways to rejuvenate your aging iPhone, restoring it to its former glory. By implementing these simple steps, you can unlock the full potential of your iPhone and enjoy a seamless mobile experience once again.1. Free Up Space to Enhance Performance

When your iPhone’s storage nears or reaches capacity, it may experience performance issues. To alleviate this, consider removing unused apps and deleting unnecessary photos and videos. Alternatively, you can move valuable files to cloud storage.

iOS 11 introduces several tools to assist you in reclaiming storage space. Navigate to Settings > General > Storage & iCloud Usage and select Manage Storage under the Storage section.

A comprehensive chart displays your storage usage and remaining free space. Beneath the chart, you’ll find recommendations for saving storage, including the new features:

  • Offload Unused Apps: Automatically remove apps you rarely use while preserving their data.

  • iCloud Photo Library: Store your photos and videos in the cloud, freeing up space on your device.

  • Auto Delete Old Conversations: Automatically delete text messages and attachments older than a year.

  • Review Large Attachments: Identify and delete large media files to recover valuable storage.## 2. Embrace High-Efficiency Image File Format (HEIF)

iOS 11 has introduced new file formats for high-efficiency image and video capture. The HEIF (High-Efficiency Image File) format is used for photos while the HEVC (High-Efficiency Video Coding) format is employed for videos. If you’re like most iPhone users, your photos and videos likely consume a considerable portion of your device’s storage.

Follow these simple steps to activate this transformative file format:

  • Go to Settings
  • Select Camera
  • Choose Formats
  • Switch to High Efficiency

By opting for the HEIF/HEVC formats, you’ll be able to take advantage of their space-saving properties without compromising image or video quality.


This feature is not available on all iPhone and iPad models. To capture images in HEIF and record videos in HEVC, your device must be equipped with the A10 Fusion chip or a more recent processor. Here’s a list of compatible devices:

  • iPhone 7
  • iPhone 7 Plus
  • iPad Pro 10.5-inch
  • iPad Pro 12.9-inch (second generation)
  • Any device with a more recent processor than the A10 Fusion## 3. Update Your Apps

App Optimization for iOS 11

Outdated applications may experience compatibility issues and performance deficiencies when running on the latest iOS 11. To ensure optimal functionality and speed, it is crucial to regularly update apps after upgrading your iPhone.

Upon completing the iOS 11 update, navigate to the App Store application. Tap the Updates tab, where you will find a comprehensive list of pending app updates. To expedite the process, tap Update All to seamlessly update all eligible apps with a single click.

This simple step ensures that your apps are compatible with the new iOS version, optimizing their performance and enhancing your overall user experience.

4. No Automatic Updates

Background processes in iOS 11 streamline your user experience. For instance, apps update themselves in the background, eliminating the need to monitor the increasing App Store badge notification.

However, background app updates consume device CPU and battery. To disable this feature and update apps manually, navigate to the App Store app.

  1. Access Settings > iTunes & App Store.
  2. Toggle the Automatic Downloads switch to disable Updates.

Additionally, the other options in this section – Music, Apps, and Books & Audiobooks – allow you to share downloads across your iOS devices. When enabled, new purchases from the iTunes Store, App Store, or iBooks Store automatically sync across your devices.

5. Deactivate Background App Refresh

Understanding Background App Refresh:

Background App Refresh (BAR) is a feature that allows apps to update their content in the background, even when you’re not actively using them. This can be convenient, especially for apps like social media or news feeds that provide real-time updates. However, BAR can also drain your battery and consume valuable CPU cycles.

Managing Background App Refresh:

  • Disable BAR entirely: Go to Settings > General > Background App Refresh and toggle the switch off. This will prevent all apps from refreshing in the background.
  • Disable BAR for specific apps: If you want to keep BAR enabled for certain apps but not others, you can do so by going to Settings > General > Background App Refresh and selecting the apps you want to disable it for.

Benefits of Disabling BAR:

  • Improved battery life: By preventing apps from refreshing in the background, you can conserve battery power.
  • Increased performance: Disabling BAR can free up CPU cycles and improve overall performance, especially on older devices or when running multiple apps simultaneously.


  • Missed notifications: If you disable BAR for social media or other apps that rely on real-time updates, you may miss notifications when you’re not actively using the app.
  • Delayed content updates: Disabling BAR may delay content updates in apps, such as new posts or messages.


Whether or not to disable Background App Refresh depends on your individual needs and preferences. If you value battery life and performance above instant updates, consider disabling it entirely or for specific apps. If you prioritize real-time notifications and content updates, you may choose to keep BAR enabled for those apps.## 6. Enhance Performance: Reduce Transparency and Motion Effects

Quintessential Guide to optimizing your mobile device for peak performance, using motion and transparency effects.

You can improve the speed and enhance the user experience of your mobile device by disabling or reducing certain motion and transparency effects. Here’s how:

  • Reduce Motion:

    • Navigate to Settings > General > Accessibility > Reduce Motion.
    • Enable the “Reduce Motion” toggle.
  • Disable Auto-Play Message Effects:

    • Disable the “Auto-Play Message Effects” option within the Accessibility settings to remove animations from text messages.
  • Reduce Transparency:

    • Return to the Accessibility screen and select “Increase Contrast.”
    • Enable “Reduce Transparency” to diminish transparency and blur effects, enhancing legibility and potentially improving performance.

By making these adjustments, you can minimize the resource-intensive tasks performed by your device’s processor, resulting in smoother, more responsive performance.## 7. Reign in Location Services: A Battery-Saving Strategy

Even more so than performance, location services can significantly deplete your battery life. If you’ve noticed an unusually rapid battery drain on your iOS device running iOS 11, it’s time to reassess which apps have unrestricted access to your location via GPS.

iOS 11 empowers you with unprecedented control over location access:

Previously, developers were limited to offering a binary choice of either “Always” or “Never” location tracking. However, iOS 11 introduces a more nuanced option: “While Using the App,” allowing you to grant location access only when the app is actively being used.

To fine-tune location permissions:

  1. Navigate to Settings > Privacy > Location Services.
  2. Review and adjust the location settings for each app that utilizes location services. Opt for “While Using the App” whenever possible.

By implementing this strategic approach to location services, you’ll effectively conserve battery life without sacrificing essential app functionality.## FAQs
