A deep dive into the two smartphone operating systems that will make your device run as smoothly as a new one. While the basic method to restore smooth performance is similar—clearing storage and reducing processing load—both iOS (iPhone) and Android have unique hidden features. If properly configured, even older devices will respond noticeably faster.
iOS is known for its stability, but slowdowns often come from full storage or battery degradation causing the system to throttle performance. One key setting to consider is enabling the feature "Offload Unused Apps." This feature automatically removes apps you haven’t used for a long time to free up space, while keeping the app’s data and documents intact (the app icon will show a small cloud). You can re-download and use the app immediately without data loss. To enable, go to Settings > App Store > turn on 'Offload Unused Apps.'
Reduce Transparency. Beyond reducing animations, turning off blur effects and transparent backgrounds in places like the Control Center reduces the load on the graphics processor, resulting in a smoother device. To activate, go to Settings > Accessibility > Display & Text Size > Enable Reduce Transparency. Additionally, clear Safari cache and history. The iPhone’s main browser often accumulates a large amount of cache and cookies if never cleared. Go to Settings > Safari > scroll to the bottom and tap Clear History and Website Data.
An important step is checking and managing battery health. If the battery capacity is below 80%, iOS slows down the CPU to prevent unexpected shutdowns. Check this at Settings > Battery > Battery Health & Charging. If the battery is degraded, replacing it is the surest way to restore full speed.
Android is an open and highly flexible system, offering deeper customization options, especially for managing memory (RAM).
Unlock Developer Mode to speed up animations. This secret trick dramatically improves Android smoothness. Go to Settings > About phone > Software information > tap 'Build number' 7 times. Then return to the main Settings page, scroll to the bottom to find 'Developer options.' Inside, set all three animation scale settings to 0.5x.
Use the Device Care feature. Almost every Android brand includes a device cleaning app. For example, Samsung’s is at Settings > Battery and device care. Tap 'Optimize now' to clear RAM, close background apps, and delete junk files with one click.
Enable RAM Plus / Virtual RAM. Many newer smartphones allow you to allocate part of storage to act as additional RAM, improving app switching performance. Check and activate this feature under Device Care or Memory settings, depending on the brand.
Set the device to restart automatically. Instead of manually restarting, Android lets you schedule automatic restarts. Go to Settings > General management > Reset > Auto restart at set times. It’s best to schedule this around 3 a.m. on days off to allow the system to clear itself.
Consider switching to Lite versions of apps if your device is older or has less than 4GB of RAM. Using lightweight app versions that consume fewer resources—such as Facebook Lite, Messenger Lite, or TikTok Lite—can help. These are available for free on the Play Store.
