Slow opening of applications on Android, when after pressing an icon the screen freezes for several seconds, is most often caused by a lack of RAM or accumulated cache, and not by the aging of the device itself.
Slow launch of apps can be caused by many factors: from a simple lack of RAM memory RAM before conflicts of background processes. In this article, we will analyze in detail the mechanisms of the operating system that affect the response speed, and we will propose specific steps to optimize your gadget without the need to do a complete data reset.
Analysis of RAM and processor load
The first and most obvious reason for slow operation is the lack of free resources. The Android operating system is designed in such a way that it strives to keep as many running applications as possible in RAM to ensure instant switching between them. However, when RAM is filled to capacity, the system has to constantly unload old processes and load new ones from the internal drive, which takes time.
You can check the current memory state through the developer menu or third-party utilities. If you see that less than 15-20% of the total volume is free, this is a direct signal to action. Heavy games, social networks and instant messengers consume resources not only during use, but also in the background.
It is also worth paying attention to the load on the central processor. Sometimes one malfunctioning application can “eat up” all the computing power, forcing other apps to wait their turn. In such cases, the system becomes sluggish and response to touch is delayed.
- 📊 Check memory usage statistics in the battery settings.
- 🚀 Close applications that you are not currently using.
- 🔋 Disable power saving mode if it limits the frequency processor.
It is important to understand that forcibly stopping all processes in a row is not always useful. The Android system knows how to manage memory wisely, and constant manual cleaning can even slow things down, forcing the processor to reinitialize system services.
Cleaning application cache and system garbage
Accumulated cache data is a double-edged sword. On the one hand, they speed up the restart of apps by saving temporary files. On the other hand, an overgrown cache may contain corrupted data or take up a critical amount of space on the internal drive, which directly affects the speed of reading data.
When the storage is more than 90% full, the speed of writing and reading files drops significantly. This is a physical feature of flash memory. Therefore, regularly clearing the cache of heavy applications, such as Telegram, YouTube or Instagram, is a must to maintain performance.
You can clear the cache for each application separately through the settings menu or use the built-in Storage Cleaner tool, which is available in shells MIUI, One UI and others. Deleting the cache does not affect your personal data, logins or progress in games.
☑️ Checklist for clearing memory
For deep cleaning, you can use a computer by connecting a smartphone by USB and manually deleting temporary folders in the /Android/data and /Android/obbdirectories, but this requires care not to delete the necessary game files.
The influence of interface animation on the perception of speed
Often the problem is not the actual loading speed application, but in how long the animation of its opening lasts. By default, Android uses 1x animation ratios, which means standard transition durations. Decreasing these values creates a subjective feeling of instant system operation.
To change these settings, you must activate developer mode. To do this, go to Settings → About phone and quickly click 7 times on the item Build number. After the message “You have become a developer” appears, a new section will appear in the settings menu.
In the section For developers find three items: “Window Animation”, “Transition Animation” and “Animation Duration”. Change the value in each of them from 1x to 0.5x or disable the animation completely. Visually, the interface will become much faster.
⚠️ Attention: Completely disabling animation (value 0) can make the interface jerky and less pleasing to the eye. It is recommended to stay at 0.5x for a balance between speed and smoothness.
This method does not free up processor resources, but it saves you time and nerves by reducing the time you wait for visual effects each time you start the app.
If after resizing the animation the interface becomes too fast and you cannot follow the transitions, return the value to 0.75x - this is a compromise option.
Problems with the internal storage and memory card
The speed of applications directly depends on the speed of reading data from the media. If your smartphone uses an old type of memory or the internal storage is critically full, loading application resources will take a long time. This is especially true for budget models with memory type eMMC.
A common mistake users make is installing heavy applications on a memory card microSD. Even fast U3 class cards are inferior in random reading speed to the built-in memory of a smartphone. Applications installed on an external card often take longer to open and may freeze during operation.
It is recommended to store only media files on the memory card: photos, videos and music. All system applications and games must be installed in the internal memory of the device to ensure maximum performance.
| Storage type | Read speed (approximate) | Impact on startup | Recommendation |
|---|---|---|---|
| Built-in UFS 3.1 | High (>1000 MB/s) | Instant launch | Ideal for all applications |
| Built-in eMMC 5.1 | Medium (~300 MB/s) | Normal startup | Suitable for most tasks |
| MicroSD Class 10 card | Low (~90 MB/s) | Noticeable latency | Only for media files |
| Memory full (>95%) | Critical low | Strong brakes | Urgent cleaning required |
If You noticed that the problem occurred after installing a memory card, try removing it and checking the speed of the phone without it. This will help diagnose the problem of slow media.
Background processes and startup applications
Many applications tend to launch immediately after turning on the phone and continue to work in the background, even if you are not using them. Mail synchronization, geolocation, updating news feeds - all these processes take up processor and RAM resources.
In the Android settings, you can limit background activity for specific apps. Go to Settings → Applications, select the application you don’t need in the background and find the “Battery” or “Battery Consumption” item. Set a limit on background activity or disable autorun.
Hidden processes in the developer menu
In the developer menu there is an item “Background process limit”. Setting the value to “No more than 2 processes” can radically speed up older smartphones, but may lead to messengers stopping sending notifications instantly.
It is also worth checking for viruses or miners that disguise themselves as system processes. If the phone heats up when idle and applications open slowly, scan the system with a reliable antivirus, for example Dr.Web or Kaspersky.
⚠️ Attention: Do not disable background processes for system applications such as “Phone”, “Messages” or “Google Play Services”, otherwise the stable operation of the operating system will be disrupted.
Resetting settings and updating software
Sometimes software errors accumulate for years, leading to performance degradation. Check for system updates in the menu Settings → System → Software update. Manufacturers often release patches that optimize memory performance and fix bugs.
If updates do not help, the last resort is to reset to factory settings. Before this procedure, be sure to create a backup copy of all important data, since all information from the phone will be deleted.
After the reset, do not restore all applications from the backup copy at once. Install only the essentials and watch the device work. Often the problem lies in one specific application that you installed a long time ago.
A radical factory reset (Factory Reset) in 90% of cases returns the smartphone to the speed of a new device, if the problem is not related to physical breakdown of components.
Remember that after updating the firmware, the system can optimize applications in the background for several hours. At this time, the phone may work slower than usual - give it time to complete the process.
Frequently asked questions (FAQ)
Why did applications take longer to open after updating Android?
After a major system update, files are re-indexed and application databases are optimized. This is a normal process that can take from several hours to a day. Also, the new version of the OS may require more resources than the old one.
Does closing applications through the multitasking menu help?
In modern versions of Android, forcefully closing applications from the multitasking menu often has the opposite effect. The system spends more energy and time re-launching the application from scratch than keeping it minimized in RAM.
Can a widget on the home screen slow down the launch of other apps?
Yes, active widgets, especially those that constantly update data (weather, news, exchange rates), consume processor and network resources. Try removing unnecessary widgets from the desktop and check if the operating speed has changed.
Does power saving mode affect the speed of opening applications?
Absolutely. In hard power saving mode, the system limits the processor clock speed and prohibits background activity. This significantly slows down the launch of any apps. Disable this mode for full functionality.
What to do if only one specific application opens slowly?
The problem is most likely on the side of the application itself. Try clearing its cache and data, checking for updates in the store Google Play or uninstalling and installing it again. If the problem persists, the application may be poorly optimized for your phone model.
