Modern applications are becoming more and more resource-demanding, and even yesterday, fast smartphones today can noticeably slow down. If your device is running an operating system Android 9 Pie, you may already have experienced a slow interface, long app launch times, or sudden freezes. This is a natural process of software aging, but it does not mean that it’s time to throw the gadget into the dustbin of history.
There are many proven ways to restore the former agility of your device without the need to reflash or buy new hardware. Proper cleaning of the cache, disabling unnecessary animations and proper control of background processes can work wonders. In this article, we will look at specific steps that will help revive the performance of your smartphone.
⚠️ Attention: Before starting deep optimization, make sure that the battery charge is at least 50%, since some processes can consume significant energy, and a sudden power outage during system changes is undesirable.
Analyzing occupied space and clearing memory
The first thing you should pay attention to is how full the internal memory is. When free space reaches zero, the system has nowhere to place temporary files and cache, which critically reduces response speed. Internal storage should be filled no more than 80-85% for stable operation of the file system.
Start by deleting applications that you do not use. Users often forget about apps that hang around like dead weight, but are updated in the background and take up space. Go to Settings → Applications and notifications → Show all applications and carefully study the list.
Pay special attention to multimedia files. High-resolution photos and videos quickly eat up gigabytes. If you have Google Photosinstalled, use the "Free up space" function, which will delete pictures from your device that are already saved in the cloud.
- 📸 Delete duplicate photos and screenshots that are no longer needed.
- 🗑️ Clear the "Downloads" folder, where APK installation files are often accumulated.
- 📱 Disable or delete pre-installed applications (bloatware), if the manufacturer allows it.
- 🎵 Check the cache of instant messengers (Telegram, WhatsApp), which may occupy tens of gigabytes.
⚠️ Attention: Shell interfaces from different manufacturers (Samsung, Xiaomi, Huawei) may differ. The names of the menu items may vary, but the logic remains the same: we are looking for the “Storage” or “Memory” section.
Managing background processes and applications
Many apps continue to run even after you close them. They track location, sync data, or simply wait for notifications, all while using up RAM and CPU time. On Android 9 control of background processes has become stricter, but manual control is still required.
You can limit background activity for specific applications. Go to the application settings, select "Battery" or "Charge Consumption" and set the mode to "Limited" or "Battery Saver". This will prevent the app from launching without your knowledge.
It is also worth checking which applications have access to geolocation. Constantly polling the GPS module is one of the most resource-intensive processes. Leave "Always" access only for navigators, and for the rest, select "Only when using."
☑️ Audit background applications
There is a hidden developer menu that allows you to see all running services. Activate it by clicking 7 times on the build number in the "About phone" section. Then, in the developer menu, find the “Running services” item to see what exactly is loading the system right now.
Setting up interface animation for visual acceleration
One of the most effective and safest ways to make your phone visually faster is to reduce the animation time. Standard transitions between windows, opening applications and minimizing tasks take a certain amount of time, which can be reduced significantly.
For this, you will again need the developer menu. Find the Drawing section and pay attention to three options: Window Animation, Transition Animation, and Animation Duration. The default value there is 1x.
Change the value to 0.5x or even disable the animation completely (No animation). The difference will be noticeable instantly: the interface will become more twitchy, but the system's reactions will become lightning fast. This is especially true for devices with small amount of RAM.
⚠️ Attention: Completely disabling animation can make the interface less pleasant and understandable, since the visual connection between actions will disappear. It is recommended to stay at a value of 0.5x.
If, after reducing the animation, the interface begins to twitch, return the value to 0.75x - this is a compromise between speed and smoothness.
Using lightweight versions of applications
Modern versions of popular social networks and instant messengers are acquiring functions that turn them into heavyweight ones monsters. They require a lot of processor resources and memory, which is too much for older devices with Android 9.
The solution is to switch to _lite_ or _GO_ versions of applications. These apps are designed specifically for devices with limited capabilities or unstable Internet. They consume less traffic, take up minimal memory space, and work much faster.
Consider replacing core applications with their lightweight counterparts. For example, instead of full-fledged Facebook, use Facebook Lite, and instead of regular YouTube, YouTube Go or just the web version in the browser.
| Full version | Lite alternative | Save space |
|---|---|---|
| Facebook Lite | up to 90% | |
| Instagram Lite | up to 85% | |
| Google Maps | Google Maps Go | up to 80% |
| Skype | Skype Lite | up to 75% |
Installing such versions will not only speed up the operation of specific apps, but will also reduce the overall load on the system, freeing up resources for other tasks. This is especially important if you actively use social networks during the day.
Reset settings and clear the system cache
If software methods do not give the desired result, you can resort to more radical measures. Clearing the cache of all applications at once can help get rid of accumulated software garbage, which sometimes causes conflicts.
This can be done through the Recovery Mode menu or through standard settings. In the "Storage" section there is often a "Clear cache" button, which is safe for your personal data (photos, contacts, files will remain in place).
In extreme cases, when the phone is unbearably slow, a full reset to factory settings helps. This will return the device to its out-of-the-box state. Before this procedure, be sure to make backup all important data.
How to perform a reset through the menu?
Hold down the power and volume buttons (the combination depends on the model), select Wipe Data/Factory Reset and confirm action.
After the reset, do not rush to install hundreds of applications at once. Install only the essentials and watch the system work. Often the cause of slowdowns is one specific, poorly optimized application.
Additional power saving settings
Power saving mode not only extends battery life, but also limits processor performance, which can be useful in some scenarios, but is harmful to speed. However, on older devices, smart use of power settings can help.
Check that you don't have Super Power Saving mode turned on all the time. In this mode, the phone operates with reduced functionality. For everyday use, it is better to set up an individual saving mode, turning off only background synchronization and vibration.
It is also worth disabling “Adaptive Brightness” if the light sensor does not work correctly, and remove live wallpapers. A static black image on AMOLED screens or a simple dark screensaver on IPS saves GPU resources.
- 🔋 Turn off keyboard and system vibration to save micro-movements.
- 📶 Remove widgets from the home screen that constantly update data (weather, news).
- 🌡️ Check the case temperature; overheating causes throttling and severe slowdown.
- 📡 Turn off Bluetooth and NFC if you are not using them right now.
⚠️ Attention: Do not use “accelerator” applications (Clean Master and analogues) from the Play Market. They often themselves are a source of advertising and background processes, slowing down the phone even more than before they were installed.
The most effective way to speed up is an integrated approach: clearing memory, disabling animation and abandoning heavy versions of applications give the overall result.
Will flashing your phone to a newer version of Android help?
Not always. If your phone is old, the new version of Android may be too heavy for its processor. However, switching from custom but buggy firmware to a stable official version can improve the situation.
Do you need to remove the antivirus to speed it up?
Yes, if you use your phone carefully and do not visit dubious sites. Third-party antiviruses often hang in the background and scan the system, consuming resources. Built-in Google Play Protect usually copes with basic protection.
Does a full contact memory affect the speed?
Almost no. The number of contacts in the phone book does not affect the processor performance or the speed of opening applications if the contact database is not damaged.
Is it worth buying an SD memory card for speedup?
No, the memory card does not speed up the system. Moreover, if the SD card stores applications or if it has a low speed class, the phone may work even slower due to the long data read time.
Is it true that the dark theme speeds up the phone?
No, the dark theme (Dark Mode) only changes the colors of the interface. It can save battery power on AMOLED screens, but this does not affect the processor speed and the number of FPS in any way.
