Fixing iPhone 14 Plus Slow App Launches After Battery Saver Activation

Introduction

The iPhone 14 Plus brings a sleek design and powerful hardware, but even the best devices can run into quirks when software settings clash with user expectations. One such annoyance is a noticeable delay in launching apps right after enabling Battery Saver, also known as Low Power Mode. The mode is intended to conserve battery life by throttling background tasks, reducing visual effects, and limiting some processes, but the trade‑off can be a sluggish startup time for your favorite apps.

For many users the problem feels random or temporary, but for others it persists and becomes a daily nuisance. The good news is that the issue is usually resolvable through a handful of adjustments, some system resets, or a firmware update. In this guide we’ll walk through why the delay happens, diagnose common triggers, and provide step‑by‑step solutions that bring back snappy app launches without sacrificing battery life.

Understanding Low Power Mode on iPhone 14 Plus

Low Power Mode (LPM) is a system‑wide feature that helps extend battery life by making intelligent compromises. When LPM is activated:

• Background app refresh is turned off by default, preventing apps from fetching new data while you are not actively using them.
• Automatic downloads and updates are paused.
• Visual effects such as dynamic wallpapers and animations are reduced or disabled.
• Some system processes, like location services, are slowed down or put on a stricter schedule.
• The CPU and GPU run at a slightly lower clock speed to reduce power draw.

These changes can cause a noticeable slowdown in launching apps, especially those that rely heavily on background services or network access to display fresh content immediately upon opening. The iPhone 14 Plus, however, has a robust processing engine that can handle these restrictions smoothly in most cases, so when you notice a lag, it usually points to a specific misconfiguration or software issue.

Symptoms of App Launch Delay

Before jumping to fixes, it helps to confirm that the problem is indeed related to Low Power Mode. Look for these indicators:

1. Consistent delay after toggling LPM on – You notice a pause of a few seconds when you press an icon, but the lag disappears when you return to normal power mode.
2. Certain apps are slower than others – Messaging apps, social media feeds, or news apps often show the delay because they refresh data on launch.
3. Battery saver stays on during usage – The orange battery icon in the status bar indicates that LPM is active.
4. No general performance degradation – The phone runs normally otherwise; the only issue is the launch delay.

If you are not sure whether LPM is enabled, you can verify in Settings > Battery where a switch next to “Low Power Mode” shows its status.

Why Apps Slow Down in Low Power Mode

Several underlying factors explain the slowdown:

• Background refresh disabled – Apps that normally fetch updates while idle now wait for a network request to complete once you open them. If the network is slow or the server is busy, the app appears to take longer to launch.
• Reduced CPU/GPU frequency – While the processor can still run apps, the lowered clock speed may translate into longer rendering times, especially for graphics‑heavy applications.
• Limited network bandwidth – iOS prioritizes battery over speed, which can throttle the data rate for certain background or foreground tasks.
• Cache and data handling changes – Some apps purge or re‑index data when LPM is enabled to reduce storage usage, resulting in a heavier load when launched again.

Because each app manages its own data flow differently, the impact can vary widely. Knowing this helps you focus on the right settings.

Quick Fixes You Can Try Right Now

Below are a few simple steps that often resolve the delay without deeper troubleshooting.

1. Toggle Low Power Mode Off and On Again

Sometimes the mode can glitch. Switch it off (Settings > Battery) for a minute, then turn it back on. This resets the system’s optimization routines.

2. Restart Your iPhone

A reboot clears temporary caches and can fix many transient issues. Hold the side button and either volume button until the power slider appears, slide to power off, wait a few seconds, then power back on.

3. Update iOS

Apple frequently patches performance bugs in new releases. Check for an update by navigating to Settings > General > Software Update. If an update is available, download and install it.

4. Verify App‑Specific Settings

Some apps allow independent background refresh control. Go to Settings > General > Background App Refresh and ensure that the apps you use most are toggled on even when LPM is active.
Note: iOS respects Low Power Mode but still permits individual apps to opt‑in for refresh if you manually enable it.

5. Clear App Cache (If Supported)

Certain apps provide a “Clear Cache” option within their settings. Clearing cached data can remove stale files that cause slow starts.

If none of these quick fixes solve the problem, we move on to more detailed diagnostics.

Detailed Troubleshooting Steps

When the issue persists after basic remedies, follow a structured approach:

1. Examine Battery Health

• Settings > Battery > Battery Health.
• If the maximum capacity is below 80 % or the “Peak Performance Capability” shows reduced performance, consider a battery replacement. A worn‑out battery can affect CPU performance under LPM.

2. Disable Background App Refresh Completely

Although this may seem counterintuitive, turning off background refresh for all apps can actually reduce the initial load time when LPM is on because apps won’t have to reload data on launch.

• Go to Settings > General > Background App Refresh, switch it off.

3. Reset All Settings

This action preserves apps and data but resets system settings, potentially clearing corrupted configuration.

• Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.

4. Check Storage Usage

A nearly full storage can slow down read/write operations.

• Settings > General > iPhone Storage.
• If the free space is below 10 % of total capacity, delete unused apps, photos, or offload large files to iCloud.

5. Reinstall Problematic Apps

If the delay occurs only with a specific app, uninstall and reinstall it:

• Hold the app icon, tap “Remove App”, confirm, then download from the App Store again.

6. Disable “Reduce Motion”

In Settings > Accessibility > Motion, toggle off “Reduce Motion.” While this option saves battery by limiting visual effects, it can interfere with app animations, especially during launch under LPM.

7. Force‑Quit All Apps

Double‑tap the side button to open the app switcher, swipe all apps off the screen. After a brief pause, launch your desired app.

• This clears any stuck processes that might be affecting launch speed.

Advanced Solutions for Persistent Issues

If you’ve gone through all the above and the delay remains, try these more technical adjustments.

1. Use Guided Access to Lock a Single App

Guided Access (Settings > Accessibility > Guided Access) can force the device to run only one app in the foreground, thereby eliminating background interference. Enable it for a test period to see if launch speed improves.

2. Monitor Network Performance

Open Settings > Cellular or Wi‑Fi, tap the current connection, and note the signal strength. A weak network can cause slower data fetching on app launch. Switch to a stronger Wi‑Fi network or reset network settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings).

3. Check for Third‑Party Battery‑Saving Apps

If you installed any battery‑saving utilities outside of Apple’s built‑in LPM, uninstall them. Third‑party apps might interfere with system optimizations.

4. Contact Apple Support

Persistent launch delays could hint at deeper firmware issues or hardware faults. Use the Apple Support app or visit an Apple Store for a diagnostics check.

Preventive Measures to Keep Apps Snappy

Once you’ve resolved the lag, maintain performance with these habits:

• Keep iOS and apps updated – Updates often contain performance tweaks.
• Use “Background App Refresh” selectively – Enable it only for essential apps.
• Monitor battery health – Replace the battery before capacity drops below 80 %.
• Keep storage healthy – Aim for at least 15 % free space.
• Disable unnecessary visual effects – Reducing motion can free up GPU cycles, but only if you need the battery saving benefit.
• Turn off Low Power Mode only when needed – Use it sparingly to avoid constant throttling.

Frequently Asked Questions

Q: Will turning off Low Power Mode solve the app launch delay permanently?
A: It removes the restriction that causes the delay, but at the cost of higher battery drain. You can enable LPM again after launching apps if you need to conserve battery later.

Q: Does battery health affect Low Power Mode performance?
A: Yes. A degraded battery may not provide enough power for high‑frequency CPU usage, so the system reduces performance more aggressively, leading to slower app launches.

Q: Can I set apps to refresh in the background even when LPM is on?
A: iOS does not allow background refresh while LPM is active. You must toggle LPM off to let apps refresh in the background.

Q: Is there a way to keep Low Power Mode active but still have fast app launches?
A: The best compromise is to disable background refresh for all apps, which can reduce initial data fetches. Additionally, keeping the phone’s storage healthy and updating iOS helps maintain performance.

Q: Should I manually reset settings every time I enable LPM?
A: No. Resetting settings is a one‑time troubleshooting step. After that, normal usage patterns should not require it.
