Why Does My Tablet Lag When I Switch Apps And How To Speed It Up

Tablets have become essential tools for work, entertainment, and communication. But nothing disrupts the experience faster than noticeable lag when switching between apps. What once felt seamless suddenly becomes a frustrating wait. The issue isn’t always due to aging hardware—often, it’s a combination of software inefficiencies, background processes, and storage strain. Understanding the root causes allows you to take targeted steps toward restoring smooth multitasking.

Lag during app switching typically stems from how your tablet manages memory (RAM), background tasks, system updates, and available storage. Over time, these factors compound, especially if usage patterns haven’t changed but demands on the device have increased. The good news is that most performance issues are fixable with practical adjustments and regular maintenance.

Understanding App Switching and Memory Management

When you switch between apps, your tablet relies on Random Access Memory (RAM) to keep recently used applications active in the background. This allows for quick resumption instead of reloading each app from scratch. However, every tablet has a finite amount of RAM. Once that limit is reached, the system starts closing background apps or struggles to reload them efficiently, resulting in delays.

Modern operating systems like Android and iPadOS use sophisticated memory management to prioritize active tasks. Still, they can only do so much when overwhelmed. For example, if you're running a video editing app, a browser with multiple tabs, and a messaging service simultaneously, your tablet may exceed its memory capacity. This forces the OS to constantly swap data between RAM and internal storage—a process known as \"thrashing\"—which dramatically slows performance.

“Memory pressure is one of the top reasons for app-switching lag. Users often don’t realize how many background services are consuming resources until performance visibly drops.” — Dr. Alan Zhou, Mobile Systems Engineer at TechFlow Labs

Tip: Close unused apps manually after heavy multitasking sessions to free up RAM and reduce memory pressure.

Common Causes of Tablet Lag During App Switching

Lag isn’t random—it follows predictable patterns tied to specific system behaviors. Identifying the cause helps determine the right solution.

• Insufficient RAM: Tablets with 2GB or less of RAM struggle with modern apps, especially those that are media-rich or require constant connectivity.
• Full Storage Capacity: When internal storage is more than 85% full, the system has less space for temporary files and cache operations, slowing down background processes.
• Outdated Operating System: Older versions of Android or iOS may lack optimizations for newer apps, leading to inefficient resource use.
• Too Many Background Apps: Notifications, sync services, and auto-updates run silently but consume CPU and memory.
• Bloatware and Unoptimized Apps: Pre-installed apps or poorly coded third-party software can hog resources without user awareness.
• Overheating: Thermal throttling reduces processor speed to prevent damage, directly impacting responsiveness.

The Hidden Impact of Cache and Temporary Files

Every app generates cache data—temporary files used to load content faster. While helpful initially, accumulated cache over months can clutter the system. Some apps fail to clean up properly, leaving behind redundant files that occupy both storage and processing power. A bloated cache doesn’t just slow boot times; it affects how quickly apps resume after being minimized.

Tip: Clear app caches monthly through your tablet’s settings to maintain optimal performance.

Step-by-Step Guide to Speed Up Your Tablet

Improving app-switching performance requires a methodical approach. Follow this sequence to address both immediate and long-term causes of lag.

1. Restart Your Tablet Weekly
   A simple reboot clears RAM, stops rogue processes, and resets network connections. It’s the fastest way to restore baseline performance.
2. Update Your Operating System and Apps
   Go to Settings > System > Software Update (Android) or Settings > General > Software Update (iPad). Install the latest OS version and ensure all apps are updated via the Google Play Store or App Store. Updates often include performance patches and bug fixes.
3. Free Up Storage Space
   Delete unused apps, offload old photos and videos to cloud storage, and remove downloaded files you no longer need. Aim to keep at least 15–20% of your storage free.
4. Clear App Caches
   On Android: Settings > Storage > Other Apps > [Select App] > Clear Cache.
   On iPad: Offload the app (Settings > General > iPhone/iPad Storage > [App] > Offload App), then reinstall it to wipe cache.
5. Limit Background Activity
   Disable background refresh for non-essential apps. On iPad: Settings > General > Background App Refresh. On Android: Settings > Apps > Special Features > Background Restrictions.
6. Disable Animations (Android Only)
   Developer Options allow you to reduce window animation scale, transition animation scale, and animator duration scale to 0.5x or off. This makes transitions feel snappier, even if underlying performance hasn’t changed.
7. Check for Malware or Resource-Hogging Apps
   Use built-in battery usage stats (Settings > Battery) to identify apps consuming excessive CPU. Uninstall any suspicious or rarely used apps showing high background activity.

Do’s and Don’ts: Best Practices for Sustained Performance

Do’s	Don’ts
Keep at least 2GB of free storage	Let storage fill beyond 85% capacity
Update your OS and apps regularly	Ignore system update notifications
Use lightweight alternatives for common tasks (e.g., Firefox Lite, Microsoft SwiftKey)	Install too many bloatware-style social media apps
Enable adaptive brightness and auto-sleep to reduce heat buildup	Leave the screen on while using intensive apps for hours
Reboot your tablet weekly	Assume “set it and forget it” applies to device maintenance

Real Example: How Sarah Fixed Her Lagging Tablet

Sarah, a freelance graphic designer, relied on her mid-range Android tablet for client meetings and sketching. She noticed increasing delays when switching between Adobe Illustrator Draw and her email app. At first, she assumed the device was simply outdated. After two minutes of diagnostics, she discovered her storage was 94% full—mostly occupied by cached design files and old project backups.

She followed a structured cleanup: deleted redundant files, cleared cache for creative apps, uninstalled duplicate note-taking tools, and enabled automatic photo backup to Google Drive. She also restricted background data for non-critical apps like weather and news widgets. Within an hour, her tablet responded instantly when switching apps. Six months later, she reports consistent performance without further lag.

This case illustrates that hardware limitations are often secondary to poor digital hygiene. With minimal effort, users can reclaim significant performance headroom.

Optimizing Settings by Tablet Type

Different tablets respond better to specific tweaks depending on their OS and specs. Here’s how to tailor your approach:

iPad (iPadOS)

• Use “Offload Unused Apps” (Settings > App Store): Automatically removes infrequently used apps while preserving documents and data.
• Turn off Parallax and Motion Effects: Settings > Accessibility > Motion > Reduce Motion. This reduces GPU load during transitions.
• Limit ad tracking: Settings > Privacy & Security > Apple Advertising > Limit Ad Tracking. Reduces background profiling activity.

Android Tablets

• Switch to a lighter launcher like Nova Launcher to reduce UI overhead.
• Use “Battery Optimization” settings to restrict background activity for non-essential apps.
• Disable live wallpapers and widget auto-refresh intervals.

Tip: If your Android tablet supports it, use Adoptable Storage (formatted SD card as internal storage) to expand usable space—but only with high-speed cards.

Frequently Asked Questions

Will factory resetting my tablet make it faster?

Yes, in most cases. A factory reset wipes all apps, settings, and cached data, returning the system to its original state. This eliminates software clutter and restores responsiveness. However, back up important data first, and only proceed if other optimization steps haven’t worked.

Can a screen protector or case cause lag?

No. Physical accessories do not affect processing speed or app performance. However, poorly designed cases that trap heat can lead to thermal throttling, indirectly causing lag during prolonged use.

Is it worth upgrading RAM on a tablet?

Generally, no. Unlike desktop computers, tablets have soldered components. RAM cannot be upgraded post-purchase. If your current device consistently runs out of memory, consider replacing it with a model that has at least 4GB of RAM for future-proofing.
