How to change screen resolution on Android

Modern smartphones are capable of producing images with better quality than most computer monitors. Along with increasing the resolution and the number of FPS, which allows you to watch videos and play without noticeable frame drops, device manufacturers offer installation of other display-related settings. For example, you can control brightness, blue light filtering, and screen resolution. This last point is the subject of this article, which combines a list of options for controlling the number of pixels used for display. Thanks to this article, you will learn how to change the screen resolution on Android and what you need to do to do this.

Method 1: System Tools

Recently, devices with high (2K and higher) resolution matrices are increasingly appearing on the market. The developers of such gadgets understand that this does not have the best effect on performance, so they add tools to the firmware for appropriate settings.

Launch the settings application, then go to the “Display” item in it (otherwise it may be called “Screen”, “Screen and brightness”, “Screen settings”, “Screen” and other similar meanings).

Next, select one of the options that is acceptable to you and click “Apply”.

The changes will be applied immediately.

This method is the simplest, but it can be used on a limited number of firmwares, which, unfortunately, do not yet include pure Android.

First way

First, we need to go to the settings of the smartphone. To do this, click on the gear in the notification shade or launch the settings shortcut through the launcher.
Next, in the settings, open the “Screen” item.

In the “Screen” item, go to “Screen image scale”.

And in this menu, move the slider at the bottom so that the interface adapts to the most convenient view.

In this case, only 4 modes are available:

very large;
average;
small;
very small.

Alas, in this method you cannot adjust the scale of the interface more widely; everything is limited to only four beams. But everything is very fast and convenient. Also, when you change the scale, there is a picture showing how the interface will look in different applications.

Method 2: Developer Settings

Screen resolution depends on the DPI (dots per inch) value, which can be changed in the developer options. This is done as follows:

Open “Settings” and go to “System” – “Advanced” – “For Developers”.

If the last option is missing, use the instructions below.

A pop-up window should appear with an input field for the DPI value, which we will change (it is recommended to remember the default one). The specific numbers vary by device, but most range from 120-640 dpi. Enter any of this sequence and tap “OK”.

At this point, work with the developer settings can be considered complete. The only negative is that the appropriate number will have to be chosen at random.

Problems and solutions

Methods don't work

Most likely, you are using methods that require rooting. Pay attention to the options with ADB, developer mode and simple phone settings - they all work even in the absence of superuser rights, which are needed for, for example, third-party programs and manual editing of the system configuration.

Applications began to work incorrectly

If you changed the settings through the presets left by the device manufacturer, this problem should be easily resolved by simply restarting the programs. In the case where a non-standard but acceptable value for the gadget was set, the solution is the same. If you specify incompatible DPI values, we recommend rolling back the actions.

To change DPI, a huge number of methods are suitable, leading to a single result. Before you begin to perform the steps described in this article, do not forget that when in the standard position, the phone is larger in height than in width.

Method 3: Third Party Application (Root)

For devices with root access enabled, you should use one of the third-party utilities that can be obtained from Google Play - for example, Screen Shift.

Launch the application after installation, then allow root use and tap “OK”.

In the main menu, pay attention to the “Resolution” option block - tap the switch to activate it.

Next, enter the number of points horizontally in the left field, and vertically in the right field.

To apply the changes, click “Continue” in the warning window.

The resolution you selected will now be installed.

How to find out Android screen resolution

Checking the characteristics

As you understand, you first need to find out what the Android screen resolution is on your device. Similar parameters are indicated in the characteristics of any gadgets. If you still have a box from your phone, most likely the information is listed directly on it or in an insert located inside. If the specifications are unknown, look for your smartphone in online stores, where such data is usually provided. Additionally, check the information provided by the Yandex.Market aggregator, since it usually contains the most reliable results.

Device settings

This information is indicated in the gadget parameters; you can see it as follows:

Open the Settings app;
Go to the “Display” section;
Find the "Screen Resolution" item. Remember the value specified in the field.

Taking a screenshot

You can take a screenshot - by default it is always created in the current resolution. To do this, just hold down the volume down and lock buttons, and then, if the smartphone prompts you to select an action related to the image, tap “Save”. When the picture is in the device’s memory, follow these steps:

Open the device gallery or file manager;
Find the image, tap on it;
Expand the drop-down menu by clicking the three dots button in the upper right corner;
Select the Details option to see the file properties;
Notice the "Resolution" line and the two numbers separated by an "x". This is the meaning needed in the context of the article.

AIDA64

A powerful tool for studying the characteristics of a device and all its components is perfect for the task when you need to find out the exact screen resolution on the Android phone you are currently using. To do this, simply follow the following procedure:

Download AIDA64 from Google Play;
Read also: How to install a Wi-Fi router: advice from an experienced system administrator
After finishing the previous step, run the program;
Open the “Display” tab;
Look at the very first point. It contains the necessary information. There is also other useful information here. For example, this way you can find out the technology of the display matrix, its refresh rate and the current load on the graphics core of the processor.

Screen Info

The name of the software speaks for itself - with its help you can find out a lot of information about the device’s screen. The process of using the utility is extremely simple:

Download the Screen Info application developed by Infamous Apps from the Play Market. It is completely free and takes up less than one megabyte;
Open the program as soon as the download process is finished;
Look at the data specified in the "Width" and "Height" blocks. These numbers are the screen resolution. The number of frames per second is written under the inscription “Refresh rate”.

Device Screen Information

A program similar to the previous one is also suitable for these purposes and has a simple interface. Just follow this procedure:

Tap “Install” on the page of this application in the Play Store;
Open Device Screen Info once you complete the previous step;
Look at the “Height” and “Width” items in the “Display (content) Area) block.”

You can also find out what part of the screen is occupied by the status bar, which serves to place notification icons and a clock. Nothing will prevent you from checking the size of the keyboard, which is subtracted from the display when typing.

Method 4: ADB

If none of the above methods are suitable for you, the most difficult option remains - using the Android Debug Bridge.

Download the required software from the link above and install it according to the instructions.
Activate the developer settings on your phone (see step 1 of the second method) and enable USB debugging on it.

On your computer, run Command Prompt as an administrator: open Search, enter command line in it, click on the result and use the options.

Read more: How to open Command Prompt as an administrator in Windows 7 and Windows 10

After launching the terminal, type in the drive letter where ADB is located and press Enter. If the default is C:, go directly to the next step.

Next, in Explorer, open the folder in which the adb.exe file is located, click on the address field and copy the path from there.

Return to the Command Prompt window, type cd followed by a space, paste the path you copied earlier, and press Enter again.

Go to the phone again - connect it to the PC and allow debugging access.

In the Command Prompt, enter adb devices and make sure the device is recognized.

If the list is empty, disconnect your phone and try connecting again. Use the following command:

adb shell dumpsys display

Carefully scroll through the resulting list, find a block named “Display Devices”, in which look for the parameters “width”, “height” and “density” - they are responsible for the resolution in width and height, as well as for pixel density, respectively. Remember this information or write it down so you can reset it in case of problems.

Now you can move on to editing. Enter the following:

adb shell wm density *number*

Replace *number* with the pixel densities you want, then press Enter.

The following command looks like this:

adb shell wm size *number*x*number*

As in the previous step, replace both *numbers* with the data you need: the number of points in width and height, respectively.

Be sure to make sure there is an x between the values!

For the changes to take effect, the phone needs to be rebooted - this can also be done via ADB, the command is as follows:

After restarting the device, you will see that the resolution has been changed. If after loading you encounter problems (the sensor does not respond well to touches, interface elements are too small or large, some software refuses to work), then connect the device to ADB again and use the commands from steps 9 and 10 to set the factory values obtained in step 8 .

Using Android Debug Bridge is a universal method that is suitable for almost all devices.

We are glad that we were able to help you solve the problem.

How to change screen resolution on Android?

The screen resolution is set by the device manufacturer itself. This parameter is determined based on the size of the device and pricing policy. Often, users do not have the resolution that is preset by the manufacturer. To a greater extent, this problem concerns gadgets with a small screen diagonal.

Due to the low screen resolution, the user faces a number of problems. For example, not every video can be watched on such a device, many good quality photos may not open, and some sites will not be displayed correctly in the browser.

Faced with these difficulties, the user involuntarily asks the question: how to change the screen resolution on an Android device? It is worth noting right away that it is impossible to change it using the standard functions of a smartphone. To do this, you will need superuser rights and a number of third-party programs.

Despite all the difficulties, some users do not want to put up with huge icons on the screen and other inconveniences that low resolution creates. If you are satisfied with everything, then it is better not to carry out the described actions, since they require certain skills and experience.

Display resolution is a certain number of pixels located on one unit of area. The more of these pixels, the sharper the image on the screen will be.

In order to change the screen resolution on Android, you need to find out what the default resolution is. You can find out this information in several ways:

view the instruction manual;

go to the manufacturer’s official website and look at the model description;

in some devices, information about display resolution can be viewed through the main menu by clicking on the “About phone” tab;

take a screenshot of the screen and see the properties of the resulting image (read our article on how to take a screenshot).

Screenshot is done by pressing the Volume button and the Power key. After this, the photo is automatically saved in the gallery. Some firmwares have a special key with which you can take a screenshot. In any case, the result will be the same.

Once the current screen resolution is known, you can proceed to installing the necessary programs.

LCD Density Modder Pro

This is one of the most popular programs that allows you to change the screen resolution on Android. Before using it, you must obtain superuser rights (root), otherwise nothing will work.

Before you start obtaining rights and increasing permission, you should take care of the safety of your data and make a backup copy. If you neglect backup, you can not only lose all your data, but also damage the gadget itself, beyond the possibility of recovery.

The LCD Density Modder Pro utility has an intuitive interface. The only difficulty is that the application is not Russified. Considering that the majority of the population more or less speaks English, difficulties should not arise.

Photo: LCD Density Modder Pro

Adjusting the resolution using this application is very easy. The main thing is not to set limit values that the device may not technically meet. The main advantages of the application include very low system requirements and the ability to cancel changes at any time.

Changing resolution without third-party programs

The display resolution can be changed without using third-party programs, but it is not possible to do without root rights. If you have already received superuser rights, then to change it you only need a file manager. You can find many such managers on the Internet (read the review of file managers on our website) and each of them will cope with the task perfectly.

The following actions must be taken:

download the file manager;
Among all the files of the device, we find the System folder;
open the build.prop file;
in the line ro.sf.lcd_density we change the numbers, which are the screen resolution.

After adjusting the values, all changes must be saved. After this, restart the device. You should not change the original values significantly. This may cause the display to not function properly. That is why it is important to find a middle ground.

Second Screen (Download)

Another application that will help expand the boundaries of the screen is Second Screen. The operating principle of such applications is identical. First you need to acquire superuser rights, and after that, using the application, you change the settings in the system files. The application can be installed absolutely free. At the same time, it has quite powerful functionality and a number of additional functions. Among the shortcomings is the lack of Russian language.

Photo: Second Screen

Many devices that run the Android system have a very low screen resolution, which does not allow you to fully use all the capabilities of the gadget. This situation can be corrected using special software and file managers. The whole procedure takes a little time. The main thing is to correctly choose the optimal display resolution that one or another model can support. The only difficulty in this process is obtaining root rights.

Dear readers! If you have any questions or comments on the topic of the article, please leave them below.

Why change the screen resolution on your phone?

Why change the screen resolution on Android, the reader may ask? A simple reason: the current resolution is insufficient, leading to poor quality of played videos and launched games. It is important to note that you can increase the resolution only if it is supported by the gadget itself - using third-party programs, which also deserve a place in the article, it is not recommended to set values that differ greatly from the standard value, since as a result the picture will have compressed quality or, conversely, parts of it will be off screen.

The second point, already concerning the reduction of this value, is related to the power consumption of the device. There is nothing complicated here either: the lower the resolution, the longer the battery lasts. This applies, for example, to Samsung devices - the manufacturer itself claims this feature of the flagships. It is also related to the maximum number of hertz, that is, the number of frames reproduced per second. In the case of FPS, an analogy can also be made - battery life increases as the image refresh rate decreases. If your phone allows you to adjust these parameters, you should not set the values too low - it is best not to lower the value below 60.

How to change screen resolution on Android device

I want to share with you another hidden property of Android devices, which, like many other things, is not available through the system settings. I know from my own experience that not all manufacturers default to a user-friendly display resolution on their tablets. This is especially true for budget seven-inch tablets, where the working area is small, and the developer sets such a size of objects that in landscape orientation the text on the display fits up to 4 lines, and this makes working with the device very inconvenient. Therefore, I want to tell you here how to change the screen resolution on Android.

What does screen resolution affect?

The main mistake when choosing a smartphone is the emphasis on the diagonal size and brightness of colors. Of course, these parameters play an important role, but the key feature is resolution. Any number of pixels represents the actual desktop space.

The quality of the image directly depends on the number of pixels available. If the device has a large diagonal that dominates the resolution, the picture will turn out fragmented and grainy. Budget models have a similar feature. If you look closely at the display, you will notice blurry, distorted and clumsy fonts.

As for media content, a demanding user will definitely be disappointed. As a rule, low image quality negatively affects the perception of video materials. Especially when it comes to films with high-quality images.

How to change screen resolution on Android: Video

I want to show you how to find out this Android screen parameter without the help of any third-party programs:

To do this, you just need to take a screenshot of the screen. By default, on all devices this is done by holding down the “Power” key and the “Volume down” key, after which the screen will be saved in the gallery.
After that, go to the gallery and open the image.
Select the properties of the picture, where you can see its size (it will be equal to the size of your display).

Changing screen resolution

Now let's move on to the main thing: about permission on Android. In order to change the Android screen resolution, you need Root rights and any file manager (I will use ES Explorer)

Open File Explorer
Go to the System folder in the root of the device.

Select the "Operations" button and select "Change".

Click “Finish”. Save changes when exiting.

How to increase font size in Google Chrome

The first step is to open the Google Chrome browser application. Then click on the “ three dots ” located at the top of the display. From the proposed list, select “ Settings ”.

Now go to the “ Special Features ” section.

On this page we see a special slider designed to scale text. To the side of it is the selected page size. Move the slider until the information becomes pleasant to read.

Once you've finished editing, click the " Back " button. On Android, all changes are saved automatically. Now you can browse websites in Google Chrome without straining your eyes.

changed the resolution to 29, what should I do?

Reset to factory settings...

Put everything in its place and not get into such jungle. Moreover, it is completely pointless. You will only harm your phone. Therefore, either put everything as it was or do a general reset to factory settings and no longer try to change the screen resolution on your smartphone tablet. NEVER ATTEMPT TO CHANGE THE RESOLUTION ON AN ANDROID DEVICE.

When saving changes to an edited file, the tablet displays a write error. There is a root

Started about one thing, finished about another. This is about the article. Using the described method, the screen resolution does not change in any way. In this line of the specified file, only the “density” of pixels (dpi) will change. Yes, icons, symbols, pictograms... will become smaller (larger if you set a higher value). But the screen resolution will remain the same. Do not mislead people!

Hello. You should not edit system files. If you tried to edit the host file, then the editor itself apparently does not have root rights. That is, the phone (or tablet) itself may be rooted, but in addition to this, you need to allow full rights for the program with which you are trying to edit the file. Moreover, not all editors and explorers have such capabilities.

I’m not going to change anything, but I took a screenshot of the screen, looked at the properties and it says “Resolution: 800×1280”, what does that mean.

Hello. This means that the display width is 800 pixels and the length is 1280 pixels. That's all. This is a normal resolution for a tablet (standard).

I changed the display to explay s02 3g when ordering and mixed up the number from 1466 to 1463. in the end everything fits, there is a picture, but not all of it fits, as if the resolution is lower. will this manipulation help?

What if I want to change the resolution in a specific application! How to be!?

Hello. It's possible, but I can't guarantee it. Moreover, all such actions are accompanied by certain risks. You do this at your own risk. I would recommend that you take the gadget for repair, but no one forbids you to try the described steps.

Help me please. What should I do? I changed the resolution to a higher one. The tablet does not work and gives a launcher and sistem error.

Hello. Try doing a general reset to factory settings and don't change the resolution anymore. It is impossible to increase the resolution, since the screen’s abilities cannot be improved programmatically. In general, I DO NOT recommend that you do such actions and get into system files, as this can lead (and will lead with a 90% probability) to disastrous consequences. Use what you have, and if you are not satisfied, then buy a more expensive device with higher characteristics.

Tell me, how to change the screen settings? I recently purchased a TV BOX on Android, connected it to a 1280 by 720 monitor. The entire image was stretched. When I connected it to a full HD monitor, the image was normal.

Hello! I recently bought a Samsung Galaxy Note Pro 12.2 tablet. I encountered the problem of constant freezes, lags and emergency shutdown due to overheating. I didn't expect this from a premium tablet. In general, I heard that resolution affects the load on the video adapter (Adreno 330/570mhz+qualcomm snapdragon 800/MSM8974/2.2mhz). Is it possible to speed up a tablet by reducing the useless resolution by half? (from 2560x1440 to 1280x720)

Hello. Read the instructions. If the device has a function for changing the resolution, then the instructions describe how to do this. Most likely, if there is such a function, then it is somewhere in the screen parameters. That is, go to “Settings” “Display” and here look for an item related to resolution (screen size or “Resolution” or something like that). Look, click, search. This will not break the device. Well, it would be advisable to clarify the model of your TV box so that I can help you. Try following this path: “Settings” Screen “Skreen” HDMI mode”. Here you can select the mode (720p or 1080p or other resolution, if available).

Hello. Yes, the CPU load and tablet resource consumption will decrease as the resolution decreases. But, you will not be able to change the resolution on the device if this is not provided by the manufacturer. Most likely, you will simply damage your tablet, which will force you to take it to a service center for an expensive repair. The risk is very high and I would not recommend trying this. The fact that your tablet is slow is most likely a manufacturing defect or a defect in the model. But nothing should slow down or lag. Overheating is a common occurrence. But lags are a problem with the bark, you can fight it, for example, by installing a more stable and proven firmware (official service one).

and if there is no line ro.sf.lcd_density =, maybe this is in different versions in different documents?

Hello, I wanted to ask, what did you do? I have the same problem...

Hello. I highly DO NOT recommend changing the resolution on Android devices this way. If the system itself does not provide such a function, then you should not go into the system records and change anything there. There is a fairly high risk of ruining the gadget, which will then require you to reflash it, which, in turn, is also accompanied by certain inconveniences, waste and risks. It's not worth it. Use the device as it was made and do not try to change anything yourself.

Tell me, is it possible to change not the resolution, but the scale? The fact is that I changed my phone from a Sony xperia z Ultra 6.4″ screen to a Lenovo k920 6″ screen. At Lenovo I am absolutely not satisfied with the scale - everything is gigantic.

I also had a Sony xperia z ultra and now I switched to the k920

Hello. I call such actions “Collective Farm”. You shouldn't be so perverted. Buy a normal screen that was designed specifically for your phone, and do not try to insert a screen from another device. Sooner or later other problems will begin to emerge. Moreover, I'm not sure if it's possible to change the scale somehow. At this point you've gotten yourself into a lot of trouble. My advice to you is to buy a normal original screen and install it, and you will have the normal size of icons and fonts.

Hello, I have an SGS6 with a resolution of 1440p, I would like to reduce the resolution to 1080p so that the games do not lag. The question is, is it possible to change the resolution in 3D games without root intervention, as is implemented on a PC. Thank you.

Go to the “Developer” options, there are changes to the display resolution. IMPORTANT. -Everything you do, you take full responsibility upon yourself. If it doesn’t work, you can return it back or do a complete “RESET” of the phone. I recommend making a full BACKUP of the entire device. Use it.

Hello. First of all, lowering the resolution will not help you. Secondly, intervention of this kind can end in failure and costly repairs. Thirdly, this is not a computer and the operating system is different. Such functions are not provided, and it’s not worth bothering with. As practice shows, such experiments in most cases end in expensive repairs.

After updating the software to version 6.0.1 Samsung, the quality of the games decreased, videos stopped playing

Hello. You should do a factory reset. After the update, most likely, the old files of the former system create certain conflicts and need to be cleaned. After the reset everything should work fine. As for games, here is a question for the developers of those same games. It is possible that they are written for Android 5 and on Android 6 they simply will not work correctly. But it's a matter of updating. That is, over time, in any case, updates will be released with optimization for the new version of Android 6. But, if resetting the parameters does not help, and the glitches remain, then you will not be able to roll back. To return Android 5, you will have to flash the phone via a computer. If the device is Samsung, then the program for flashing ODIN. Here is an article that I recommend reading before you decide to flash the device yourself - https://v-androide.com/instruktsii/obsluzhivanie/proshit-esli-ne-vklyuchaetsya.html.

Only the size of the interface has changed, nothing more, perhaps it has become faster. I checked it in Antutu, I became 10 thousand faster)

But still the goal was: increasing autonomy by switching from 2k to FHD.

I did it as it was written, but it shows it is impossible to save, how to fix it, I need help to solve this problem.

How to choose the optimal image for your smartphone screen

Before choosing a resolution, it is worth considering that a high indicator will always affect the battery life of the device. For example, you can take a device with a 5-inch screen whose resolution is 1440x2560 pixels, and a smartphone of a similar diagonal size, only with a resolution of 1080x1920. In the latter case, the battery will last twice as long, but the clarity and quality of the picture will be worse. There is a table showing the optimal resolution in terms of diagonal:

Diagonal	Permission	Density
4	800x480	250 ppi
4,5	1280x720	326 ppi
4,7	1280x720	317 ppi
5	1280x720	294 ppi
5	1920x1080	441 ppi
5,5	1920x1080	401 ppi
5,5	2560x1440	534 ppi
5,7	1920x1080	386 ppi
5,7	2560x1440	515 ppi

Ask a Question

Question to the expert

What should I do if after changing the resolution black bars appear?

Most likely, you have chosen a resolution that is not suitable for the aspect ratio. To fix the problem, you need to return the original values

I decided to change the resolution through the program, but now the image is gone. What should I do?

The only way out is to reinstall, crash reboot or reinstall the software. If this does not help, you will need to contact a service center.

I have a smartphone with a 6 inch diagonal. What resolution is better to set?

On such devices, the ideal solution would be 2560x1440. However, a lot depends on the pixel density. For example, if your parameter exceeds 400 ppi, then you can set a resolution that exceeds the proposed figure

LCD Density Modder Pro

The only app of its kind that allows you to change the DPI (pixels per square inch) value. By decreasing this number, the size of everything on the screen (pictures, icons, font, etc.) increases. It is ideal not only for those who want to change the size for convenience, but also for people with vision problems. After installing the application on your smartphone/tablet, you must:

in the settings, select the desired DPI number;
confirm your choice;
restart the device.

The changes will take effect after a reboot. The only inconvenience of the program is that you need to activate root access for it.

It is recommended that you first copy all data to a flash drive or to the cloud to avoid losing important information.

Screen resolution concept

Do not confuse resolution with display size. On devices with the same screen size, the picture may differ significantly in brightness, contrast, number of colors and other criteria. The fact is that the image quality is primarily determined by the current screen resolution, and the higher it is, the more pleasant it is for our eyes to contemplate.

In technical language, display resolution refers to the number of small dots (pixels) that fit on the screen in height and width. Pixels can be square, rectangular or hexagonal in shape.

The main units of measurement for resolution are ppi (pixels per inch), but there are other values: dpi, spi and lpi, which are used in other areas, for example, to determine print quality.

To understand what resolution is in practice, try zooming in on any image as closely as possible. It is best to run this experiment on a PC in some kind of graphics application for drawing, then you are guaranteed to see how the picture breaks up into individual points. The same principle is used when creating an image on a smartphone display, and the greater the number of composite points, the better.

Change resolution using Android Studio

To change the screen resolution on Android via the command line, you need Android Studio. You can install it on the website of the same name. After the download is complete, you must run the program and accept the terms of the agreement. Then you should simply click “next” until the files are unpacked, click “finish” and close the program. After this, you must follow these steps:

connect Android to computer via USB;
open command line;
enter the command “adb shell dumpsys display | grep mBaseDisplayInfo";
press Enter.

On the monitor screen you can see the characteristics of your smartphone or tablet. To the right of the word “Density” is a number with a screen extension. You need to enter the desired number, enter the command “adb shell wm density DPI && adb reboot” and press Enter. The new screen extension will appear after rebooting the device.

Although you can change the screen resolution on Android in different ways, it is impossible to change it higher.

The number of pixels cannot be increased due to the physical parameters of the display.

Screen resolution affects battery consumption

This seems obvious, but what many people don't know is that the higher the video and image quality, the more power the hardware requires to play videos at those resolutions. For example, if our mobile phone has a 4K resolution , it will be noticeable in our battery consumption much more than if we had the QHD option.

So, as in many other aspects, no one knows better than us whether we need to change the screen resolution. And of course, changing this option will not affect the applications in terms of usability . However, if it is judged on quality, it will be inferior in content. Although on the bright side, we will eventually notice that the battery lasts much longer than usual.

So is there any benefit to this?

Clearly yes. Although this will also depend on how each person uses their mobile phone. If you're one of those people who spends the whole day watching videos online, browsing social media, logging into apps like WhatsApp and playing all sorts of games that consume a lot of battery , it might be worth trying a lower resolution with a higher resolution. so that the mobile device can work longer without charging it. If, on the other hand, you only have to take out your cell phone for a short time each day and you occasionally use it to see Twitter and other social media, your best option may be to leave it as is. Well, it won’t have much impact on your device’s battery either.
