The operating system Android 7.0 Nougat was introduced to the world in 2016 and brought many important features, such as a multi-window mode and an improved notification system. However, over time, modern applications began to require more resources, and accumulated software garbage began to slow down the operation of even once powerful devices. If your smartphone starts to work slowly, takes a long time to open applications, or runs out of juice quickly, do not rush to buy a new model.
Proper system optimization can restore the interface to its former responsiveness and extend battery life. In this guide, we'll look at proven methods for tuning system parameters, managing memory, and disabling unnecessary services that will help you get the most performance out of your Nougat-based device. You can carry out a deep cleaning yourself and customize the system to suit your needs without the need to obtain root access.
Before taking radical measures, you need to understand what exactly is causing the slowdown. Most often, the problem lies in an excess of background processes and an outdated application cache. Let's start with basic steps that are safe for any user and do not require deep technical knowledge.
Basic cleaning and storage management
The first step to speeding up your work is to free up internal space. When free memory becomes critically low, the system begins to experience difficulties creating temporary files and swapping data. This leads to noticeable slowdowns when switching between tasks. You need to delete unnecessary files and move media content to a memory card, if such a possibility is provided by the design of your gadget.
Built-in tools Android 7 allow you to effectively manage storage without installing third-party software. Go to the settings and find the section responsible for the device memory. The system itself will analyze the occupied space and offer to delete rarely used applications or large files. Pay attention to the folder Downloadwhere installation files APK and documents that are no longer needed are often accumulated.
Particular attention should be paid to the cache of popular applications, such as social networks and instant messengers. These apps tend to accumulate gigabytes of temporary data, which slows down their launch. Regularly clearing the cache through the app settings menu helps maintain high speed. Don't be afraid to delete the cache - this will not lead to the loss of your personal correspondence or photos.
Use the "Free up space" function in the storage settings to automatically search for duplicates and large files that can be safely deleted.
For clarity, let's look at what types of data take up the most space and how to deal with them:
| Type data | Impact on speed | Recommended action |
|---|---|---|
| Application cache | High (slows startup) | Regular cleaning in settings |
| APK installation files | Medium (space consumption) | Complete removal after installation |
| Photos and videos | Low (if there is an SD card) | Transfer to external drive |
| Downloads | Average (fragmentation) | Sorting and deleting old |
⚠️ Attention: When clearing application data (not to be confused with the cache), you will lose logins, passwords and settings inside specific app. Be careful when selecting the "Erase Data" option.
Configuring animation and developer options
One of the most effective ways to visually speed up the interface is to change the scale of the animation. By default, coefficients are set that make transitions between screens smooth, but take time. Decreasing these values creates the feeling of an instant response from the system to your actions. Android 7 coefficients are set that make transitions between screens smooth but time-consuming. Decreasing these values creates the feeling that the system is instantly responsive to your actions.
To access these settings, you must activate the hidden menu. Find "Build number" in the "About phone" section and quickly tap on it seven times. After a message appears stating that you have become a developer, a new section will appear in the main settings menu For developers. This is where the sliders we need are located.
Find three items responsible for animation: window animation scale, transition animation scale and animator duration scale. Change the value of each of them from 1x to 0.5x or disable the animation altogether. This action does not increase the actual processor power, but significantly reduces the waiting time for the interface to be rendered.
☑️ Activating developer mode
In the same menu you can find the setting for limiting background processes. By default, the system allows applications to run in the background without restrictions, which can overload the RAM of older devices. Setting a limit of 2 or 3 processes will help free up resources for the active application, although this may lead to more frequent reboots of background apps.
Risk of changing the process limit
Setting a hard limit on background processes may cause the music to stop when the player is minimized, and messages in instant messengers will arrive with a delay. Use this setting with caution.
Managing startup and background services
Many applications register themselves in startup, starting to work immediately after turning on the smartphone. This leads to the fact that even before you unlock the screen, the processor is already busy processing data from dozens of apps. On devices with a modest amount of RAM, this becomes a critical factor causing lags.
In Android 7 Nougat there is no built-in startup manager in the usual sense, but you can manually prevent applications from running in the background. Go to the application settings, select the unnecessary app and find the item related to allowing work in the background or optimizing the battery. Banning background activity will prevent constant load on the central processor CPU.
It is also worth checking the list of device administrators. Some malicious or simply malfunctioning applications can gain administrator rights, which prevents their normal removal and forces them to work in priority mode. Disabling unnecessary rights in the security section can significantly relieve the system.
- 🚀 Disable synchronization for accounts that you rarely use to reduce network load.
- 🔋 Use power saving mode even during the day if speed is more important than background updates.
- 📵 Delete or disable system applications (bloatware) that are pre-installed by the manufacturer, but are not used by you.
Users often wonder whether it is worth using third-party “task killers”. Experts agree that forcing processes to end often has the opposite effect, as the system wastes resources on restarting stopped services. It is better to adjust permissions once than to constantly deal with the consequences. Android often has the opposite effect, as the system wastes resources restarting stopped services. It's better to configure permissions once than to constantly deal with the consequences.
Battery optimization and energy saving
A quickly draining battery often goes hand in hand with poor performance. When the charge drops below a certain level, the system can artificially lower processor frequencies to save energy, which leads to severe lag. Optimizing power consumption directly affects the stability of the device.
Mode Doze, introduced in previous versions and improved in Nougat, automatically puts the device into deep sleep mode when it is not in use. However, some applications may be excluded from this mode by default, continuing to wake up the processor. Check the list of applications that are allowed to ignore battery optimization and reduce it to a minimum.
Screen brightness and the use of communication modules also play an important role. Constantly searching for a network in areas with poor coverage or working GPS in the background can not only drain the battery, but also create additional interruptions for the system. Disable unnecessary communication modules when not required to ensure maximum responsiveness of the interface.
⚠️ Attention: The battery settings interface may vary depending on the manufacturer's shell (for example, MIUI, EMUI or TouchWiz). If you do not find the described items, check the official documentation for your smartphone model.
To extend battery life and voltage stability, it is recommended to avoid overheating the device. High temperatures cause throttling - an emergency decrease in processor performance. Remove the case during heavy tasks and do not use the smartphone in direct sunlight.
Power saving mode limits processor operation and background synchronization, which can temporarily reduce performance, but will save battery in a critical situation.
Resetting settings as a last resort optimization measure
If all software methods have not brought the desired result, the most radical, but often the most effective method remains - a complete reset to factory settings. Over time, the system accumulates registry errors, conflicting settings files, and remnants of deleted applications that cannot be cleaned out manually.
Before performing this procedure, it is critical to create a backup copy of all important data. The reset will delete absolutely all information from the internal storage, including photos, contacts and installed applications. Use Google cloud services or connect the device to your computer to copy files.
After the reset, do not immediately restore all applications from the backup in one fell swoop. Often it is old settings and app data that cause problems. Try setting up your phone like new, installing only the most necessary applications, and observe how it works for a few days.
Settings -> Recovery and reset -> Factory resetThis procedure returns the software to the state it was in when you purchased the device. This eliminates any software conflicts caused by updates or incorrect installation of apps. For many older smartphones based on Android 7 this becomes the only way to return a comfortable operating speed.
After resetting the settings, give the phone an hour or two alone with the charger connected. The system will perform background application optimization and file indexing, which may temporarily slow things down.
Frequently asked questions (FAQ)
Is it safe to disable system applications through settings?
Disabling standard Google or manufacturer applications through the settings menu is usually safe; the system will not allow you to remove critical components. However, disabling services necessary for the phone to function (for example, Phone or Messages) will result in the device not working.
Will installing custom firmware help speed up Android 7?
Yes, installing lightweight custom firmware (for example, LineageOS) can significantly speed up an old device, since they do not contain unnecessary software from the manufacturer. However, this requires unlocking the bootloader and carries the risk of losing the warranty or damaging the device if done incorrectly.
Why did the phone start to slow down after updating the application?
New versions of applications are often optimized for more powerful hardware and new versions of Android. On older devices, modern versions of apps may consume too many resources. Try to find and install an older, “lighter” version of the application (Lite version). Android 7 modern versions of apps may consume too many resources. Try to find and install an older, “lighter” version of the application (Lite version).
Do you need to use memory cleaning applications (Clean Master and analogues)?
In most cases, such applications do more harm than good. They themselves work in the background, show ads and aggressively unload processes, which the system immediately starts again. The built-in tools of Android 7 for memory management are quite enough.
Is it possible to increase RAM on Android 7 programmatically?
It is impossible to physically increase RAM programmatically. Some functions create a page file on internal memory, but on older devices with slow storage this often leads to even greater lags and wear out the flash memory.
