Samsung's native device maintenance feature: useful or useless?

Since I installed Android 7.0 Nougat on the Galaxy S7 Edge and later on the Galaxy S7, I have been using the "Device Maintenance" feature. For those who do not remember, Samsung has brought something like this in the Galaxy S6, through an application called "Smart Manager". Here on the site, by the way, we have already criticized this service:

With the launch of the Galaxy S7, the South Korean manufacturer brought the feature into the system and optimized it on the Galaxy Note 7 Experience UX interface. Now, with the Nougat update, the Galaxy S7 also brings such an integrated TouchWiz function. And I confess that, despite some porns, the "Device Maintenance" overview offers the user a welcome for the lay consumer. The only problem is having to use it on a premium device from the moment of purchase.

What you can do with the Device Maintenance feature

Using the optimization feature found in the device's settings menu, we soon find the quick optimization option that promises to improve the performance of the Galaxy S7 from the following actions:

  • Clear the memory;
  • Delete unnecessary files and close background applications
  • Manage abnormal battery use;
  • Scan for malware.

Then we have specific actions for each tool offered by the service.


Check the remaining battery time and the usage time of the device. For times when battery capacity is low, the system will conserve power by activating economy functions. This feature will limit device usage, such as receiving application notifications.

To do so, it will be possible to monitor applications so that they do not consume battery while in the background.

From this feature you can also configure the device for fast charging and show the battery percentage in the status bar. Both features should be enabled by default, but it's always worth checking the option in "advanced settings" (the three dots at the top of the "Battery" screen).

Performance mode

As the name implies, this option modifies the performance mode of the device according to the user's action. So if the phone is using the phone to play or listen to music, the phone can deliver the best performance for each action, saving or spending more energy. The purpose of these features is to provide the best performance for each specific action.

Here you can check the storage status in use and available. As we all know, the specified storage capacity is never available, as embedded applications and the system take up internal storage space.

Therefore, in the option "Storage" you can free space by deleting residual files such as cache and advertisements that appear on websites, apps and games. Here you also have access to SD card storage. This feature is done in conjunction with the staff of Cheeta Mobile, Clean Master developer.


The purpose of this feature is to increase the speed of your device by reducing the amount of RAM in use. To do so, you can choose which applications you would like to stop to save RAM.

The Benefits of Using Appliance Maintenance

Until reaching the current service, Samsung has done many experiments with this type of performance optimization tool. After many upgrades, we come to what today's handset maintenance feature is, and honestly, is much closer to the average user, the one who doesn't even know the meaning of RAM in a smartphone. And believe me, these are the majority of customers of Samsung or any other mobile device manufacturer today.

Once one of my bosses asked me what was my percentage use of my computer functions? Honestly, it's still maybe a little above average today, and look how I use a Mac, which is all optimized to the maximum so I don't even have to think.

Thus, the great thing about this feature is to gather in a single space all the essential information about the performance of the device as well as the protection of the system. Through this feature, for example, if a user did not activate Knox l in the first device settings, they will be guided to it from this menu. Incidentally, if a layman is not lazy, reading the explanations offered by the system will even learn more about the potential of a Galaxy S7, for example.

Finally, as this is a system native service, even those who want to use the full potential of the smartphone will be able to optimize "Device Maintenance" features and will not have to download third party applications to clean the system from time to time. because we will have a native service for that.

The Cons of Using Device Maintenance

On the other hand, easy access to the "Device Maintenance" feature also induces the user to think that their performance rating should always be at 100%. Which is a mistake, because applications running in the background have a reason to occupy RAM right now, just closing them up is immediate and lead to long-term performance issues.

Many smartphone cleaning applications promise to increase device memory and device performance. And this happens, often at the expense of clearing the application cache. It turns out that the cache is basically the storage area in which frequently used data or processes are stored for faster future access, saving time and unnecessary use of your smartphone hardware.

So triggering a cleaning service whenever your phone is slow or out of memory may seem like the best choice in the short term, but it will have a bad consequence in the future.

In addition, Samsung's new devices, such as the Galaxy S7 launched nearly a year ago, feature state-of-the-art hardware capable of efficiently charging the TouchWiz. Therefore, a performance concern for the average user should not be a concern for the first six months of use.

Final Considerations

It can be said that from the "Smart Manager" to the native "Device Maintenance" feature we had a good evolution. I'm not really a task killer fan on high-end smartphones, but I have to say that the way Samsung has narrowed the path between optimizing the battery from system settings and signaling the device's protection mechanisms, if used wisely. (knowledge) can instead optimize the performance of the device and make a Galaxy better known.

If you ask me how many times I have optimized the Galaxy S7 from this system feature since I updated the device, I will say it at least three times for testing (it didn't feel much different in any of the three attempts). But if you ask me that six months or a year from now, the answer may be different.

My suggestion is to use this feature of the system to get an overview of the device's organic operation rather than to optimize its performance.
