The operating system Android 7.0 Nougat, released several years ago, is still found on millions of devices around the world. Over time, even the most reliable gadgets begin to work more slowly, responding to touches with a delay and slowing down when switching between apps. This is a natural process of cache accumulation, memory fragmentation and app code becoming outdated to modern standards.
Many users mistakenly believe that the only solution is to buy a new phone, however deep optimization it is capable of returning the previous speed. In this article, we will look at specific technical techniques available to owners of devices based on this particular OS version. You will learn how to competently configure system processes without obtaining root access and the risk of turning your smartphone into a “brick”.
It is worth noting that the approach to acceleration should be comprehensive. You can't just delete one app and expect a miracle. It is necessary to go through several stages of setup, starting with basic cleaning and ending with changing hidden developer parameters.
Basic system cleaning and memory management
The first and most obvious step is to free up the internal storage. When free disk space approaches zero, the file system begins to operate in emergency mode, which critically slows down writing and reading data. Delete unnecessary photos, videos and old installation files .apkthat often remain after updating apps.
Pay special attention to the application cache. Over time, social networks and instant messengers accumulate gigabytes of temporary data, which does not carry a useful load, but takes up space. Go to menu Settings → Memory and evaluate which apps consume the most resources. In some cases, deleting the cache may take several minutes, but the result will be noticeable immediately.
It is also worth checking the list of installed apps for duplicates or rarely used software. Each background application consumes a portion of random access memory (RAM), which in 2016-2017 devices is usually no more than 2-3 GB. A lack of RAM causes the system to constantly unload and load processes, creating a “braking” effect.
- 🗑️ Delete all downloaded files from the folder Downloadthat are older than one month.
- 📱 Clear the browser cache Chrome or another browser through the app settings.
- 🚫 Disable autorun for apps that you do not use daily.
☑️ Quick cleaning checklist
If the situation does not improve after manual cleaning, you can use the built-in tools of the system. In Android 7.0 there is often a “Smart Manager” function or a similar service from the manufacturer (for example, Smart Manager y Samsung). These utilities are able to automatically close background processes and optimize memory allocation.
Configuring developer options to speed up the interface
The most effective method of visually speeding up a smartphone is changing the scale of animations in the developer menu. By default, the system takes time to smoothly open and close windows, which looks like a delay on older processors. Disabling or reducing these effects instantly changes the perceived speed of work.
To access these settings, you must activate hidden mode. Go to the section Settings → About phone and quickly click 7 times on the “Build number” item. After the message “You have become a developer” appears in the main settings menu, a new section will appear For developers.
Inside this menu, find the “Drawing” block. You are interested in three parameters: “Window Animation”, “Transition Animation” and “Animator Duration”. Change their value from standard 1x to 0.5x or completely disable them (No animation). This will make the interface respond to commands almost instantly.
If the interface becomes too jittery after disabling animations, return the value to 0.5x instead of disabling it completely - this will maintain smoothness, but will speed up the response.
⚠️ Warning: Do not change other settings in the developer menu if you are not sure. in their purpose. Enabling USB debugging or changing the limit of background processes can lead to unstable system operation and battery drain.
In addition to animations, in this section you can limit the number of background processes. Find the item “Background process limit” and set the value to “No more than 2 processes”. This hard limit will force the system to more aggressively unload applications from memory, freeing up resources for the current task.
Optimizing power consumption and background services
Smartphone manufacturers often implement aggressive energy saving algorithms, which paradoxically slow down the device. The system constantly puts applications to sleep and wakes them up, wasting processor resources on these switches. Android Nougat Power management has become more flexible, but requires manual configuration.
Check the list of applications that are allowed to run in the background. Often there are games or utilities that do not require constant access to the network. Limiting their activity will not only save battery power, but also reduce the load on the central processor. Go to Settings → Applications → Special access → Battery optimization.
It is also worth disabling data synchronization for those accounts that you do not need in real time. Constantly checking email, updating news feeds, and geolocation create a constant stream of data that clogs the communication channel and processor. Leave only critical services active, such as instant messengers.
| Service type | Impact on speed | Recommendation |
|---|---|---|
| Geolocation (GPS) | High | Disable when not in use |
| Photo synchronization | Medium | Only via Wi-Fi |
| Background loading | High | Limit for all applications |
| Search for Wi-Fi networks | Low | Can be disabled in settings |
Another important aspect is widgets on the desktop. Beautiful clocks, weather forecasts and news feeds require constant updates. Removing heavy widgets can significantly relieve RAM and reduce the frequency of CPU calls.
Managing startup and system applications
Many manufacturers install a large amount of pre-installed software on their devices that cannot be removed using standard methods. These apps, often called bloatware, take up space and can run in the background, consuming resources.
Although complete removal of system applications requires root accessit is possible to disable most of them. Go to the application settings, select an unnecessary app (for example, a branded theme store or an unnecessary browser) and click the “Disable” button. After this, the application will disappear from the list and stop consuming resources. Android 7.0 you can disable most of them. Go to the application settings, select an unnecessary app (for example, a branded theme store or an unnecessary browser) and click the “Disable” button. After this, the application will disappear from the list and stop consuming resources.
Be careful when disabling system components. Do not touch services related to phone, messages or system settings unless you know exactly what they do. Disabling critical components can lead to a cyclic reboot of the device.
What applications are safe to disable?
You can safely disable: branded theme stores, pre-installed games, duplicate browsers, print services (if you don’t use them), voice assistants (if you don’t use them). Do not touch: Task Manager, System UI, Google Play Services.
For advanced users, it is possible to use ADB commands via a computer for deeper cleaning. By connecting your phone to your PC in debug mode, you can remove system packages without obtaining superuser rights. However, this method requires caution and understanding of the structure of packets Android.
Resetting settings as an extreme measure of optimization
If software methods do not give the desired result, there remains a radical, but often the most effective method - a full reset to factory settings. Over time, errors, remnants of deleted apps and configuration file conflicts accumulate in the system registry that cannot be identified manually.
Before performing this procedure, be sure to create a backup copy of all important data: contacts, photos and documents. A reset will delete absolutely all information from the internal storage, returning the phone to its “out of the box” state. Go to Settings → Recovery and reset → Reset settings.
After rebooting, do not rush to install all applications at once. Try working on a “clean” device for a couple of days. If you are satisfied with the speed, start installing apps gradually, monitoring which of them causes a drop in performance. This will help identify the culprit of the brakes.
⚠️ Attention: Make sure that the battery charge is at least 50% before starting the reset. Interrupting the process by turning off the phone can damage the system partition and make it impossible to boot.
A full reset deletes not only the user's files, but also corrects system accumulation errors, often returning the device to the speed of the first days of use.
Often after a reset, users make the mistake of restoring a full copy of the system from a backup. Google or manufacturer. This may also bring back old errors. It is better to set up your phone as new by manually installing only the necessary applications.
Hardware limitations and storage drive replacement
We must not forget that software optimization has its limits due to the physical wear and tear of the equipment. Smartphones of the era Android 7.0 often used type drives eMMCthat over time lose write speed due to wear of memory cells. This phenomenon is called degradation (flash memory).
If the phone starts freezing even on the desktop after a reset, the problem may be physical. In this case, no settings will help. The only solution is to replace the device, since the cost of repair and replacement of the board is often comparable to the price of a new budget smartphone.
Overheating should also be taken into account. Dust that has accumulated inside the case over years of use impairs heat dissipation. When heated, the processor automatically reduces its frequencies (throttling) so as not to burn out, which leads to severe brakes. Cleaning the device from dust in a service center can temporarily improve the situation.
- 🌡️ Check the case temperature under load - strong heating indicates problems with cooling.
- 💾 Memory wear is manifested in long-term saving of files and opening heavy applications.
- 🔋 An old battery may not work produce the required current, causing unstable operation of the processor.
In some cases, replacing the thermal paste between the processor and the heatsink helps, but this requires complete disassembly of the smartphone and repair skills. For ordinary users, this method is too complicated and risky.
Frequently asked questions (FAQ)
Is it safe to use accelerator applications from the Play Market?
In most cases, such applications do more harm than good. They themselves consume resources, show ads and aggressively terminate processes, which the system immediately starts again. The built-in tools Android 7.0 are quite enough for normal operation.
Will flashing to a custom version of Android help?
Installing custom firmware (for example, LineageOS) can significantly speed up an old device, since they do not contain unnecessary software provision from the manufacturer. However, this requires unlocking the bootloader, which may void the warranty (if you still have one) and carries the risk of failure if installed incorrectly.
Why does the phone slow down after updating applications?
Modern versions of applications are becoming more resource-demanding. What worked quickly a year ago may load the processor more today. Try not to update heavy applications (social networks, maps) if the current version is stable, or use their lightweight versions (Lite).
Is it possible to speed up the phone by increasing the processor frequency?
Theoretically, yes, through an unlocked bootloader and a kernel with overclocking support. But in practice, this will lead to critical overheating and rapid battery drain. For everyday use on older devices, overclocking is impractical and dangerous.
Does the fullness of the memory card affect the speed of operation?
Yes, if application data is stored on the memory card or if the system constantly indexes files on a slow card, use high-speed memory cards (Class 10, UHS-I) and do not store installed apps on them if it is possible to transfer them to the internal one. memory.
