When you install a new app on your Android phone, it's quite common for it to start running on its own without you doing anything. It often seems innocent enough, but These newly installed apps can consume battery, RAM, and mobile data. Even if you don't have them open in front of you. If you notice your phone is sluggish or the battery life is plummeting, it's a good idea to learn how to limit what's running in the background.
The good news is that the system itself offers several tools for this. With a few system tweaks, a visit to the developer menu, and, if you want to take it a step further, the help of third-party apps, It is possible to prevent newly installed applications from running uncontrollably in the background.However, it's important to understand what it means for an app to remain active in the background and when it's a good idea to let it run or shut it down.
What does it mean for an app to run in the background?
On Android, when you open an application and then switch to another, the first one doesn't completely disappear: It usually remains in the background, maintaining part of its stateThis way, if you return to it, it recovers immediately without having to load all the content from scratch, which is very useful for everyday multitasking.
The problem is that while it "rests" behind, That app is still using RAM.It can make use of the processor and in many cases connects to the Internet
Something similar happens on Windows computers, where certain programs continue running even after you close the window. It's the same on Android, with the difference that The system is quite aggressive in managing memory and automatically closing processes.However, it doesn't always coincide with what you want to have open or closed.
Furthermore, many modern apps, such as social networks, email clients, messaging services, or cloud services, are designed precisely for run in the background and alert you in real time; in some cases they also involve background playback (audio or video) that requires permits and continuous activity.
That's why it's essential that, when you install something new, you're clear on that It can continue running in the background even if you think you've closed it.Just knowing this will make it easier for you to detect what's consuming resources without you realizing it.
Why it's a good idea to monitor newly installed apps running in the background
There's no need to compulsively close everything, but it is important that Bring some order to the latest apps you add to your phoneEach new installation is another candidate to fall behind, and in the long run, that will be noticeable in the user experience.
The first reason is performance: The more apps that are active at the same time, the more RAM they use. And the more you do that, the harder it is for the system to run smoothly. If your phone isn't exactly powerful, you'll notice the effect when switching between apps or returning to the home screen.
The second point is autonomy. Many background processes. They wake up the processor, make requests to the network, or maintain active services Even with your phone in your pocket, this constant trickle of work translates into fewer hours of battery life, especially if you have several newly installed apps consuming resources excessively. To control this, it's advisable to check your settings.
Mobile data consumption also comes into play. Some apps upload photos, videos, documents, or other content continuously, so that They can leak your data plan without you even noticing. if you don't restrict their activity behind the scenes.
Finally, there are notifications. Every new app that stays active is a potential source of notices, balloons, banners, and soundsIf you don't set limits, your mobile phone can become a constant barrage of notifications for offers, promotions, and reminders that you're barely interested in.
Even so, it's best not to overdo it. Android is designed to manage memory and processes automatically, and Forcing everything to shut down constantly can actually increase consumptionThis is because the system has to relaunch apps you use frequently from scratch. The key is learning to distinguish which newly installed apps are worth keeping in the background and which are better to slow down.
How to tell which apps are running in the background
Before you start blocking or uninstalling things willy-nilly, it's a good idea to check. What is actually running on your Android and how much RAM is it using? each application. For that, the developer options menu is one of the most comprehensive tools.
On most mobile phones you can activate this hidden menu with a simple process: Go to Settings > Phone information (or Device information), locate the "Build number" field and tap it several times in succession. Usually, after seven taps, the system will notify you that Developer options have been enabled.
Once activated, go back to settings and enter the new "Developer options" section. Inside, there's usually a menu called "Services in progress" or "Processes in progress", where the active apps, the services linked to each one, and the RAM that each process is using are displayed.
This view is very useful for detecting Newly installed apps that are using resources for no clear reasonIf you've just tried a simple tool and find that it keeps several services running with high resource consumption, it might not be worth it and you might want to limit or even uninstall it.
You can also combine this information with the list of recently opened apps. You have a pretty accurate picture of what's really running on your Android., beyond what appears in multitasking.
Immediate methods to stop background apps
When a newly installed app becomes stubborn—crashing, stuttering, battery draining—the normal thing to want to Cut off your activity immediately.Without installing anything extra, Android offers several ways to do this from the system settings.
The most direct way is through the problematic app's details. From Settings > Applications (or "Apps") you can Locate the newly installed app, go into its details, and use the "Force stop" option.That button immediately stops both the interface and any associated services that were running.
This kind of emergency shutdown It usually resolves specific blockages and unusual behaviors.The problem is that nothing prevents the app from restarting in the background later if it has permission to start when the device is turned on, when receiving push notifications, or when scheduling internal tasks.
If your problem is that you accumulate too many applications in multitasking, you can resort to recent apps menuYou can do this either with the corresponding button or through gestures. From there, you can swipe to the side of the ones you don't want to keep or use the "Close all" button if your Android skin offers it.
This gesture frees up some memory and clears the recent items list, but It does not guarantee that background services will stop completely.Often only the visible part closes, and the main process continues running to allow notifications to be received or synchronization to continue.
Therefore, if you want to ensure that a newly installed app stops causing problems, Forcing a stop from the settings is much more effective Instead of simply removing it from multitasking, you should uninstall an app you barely use. If it turns out to be an app you hardly ever use, the most sensible thing to do is simply uninstall it so it doesn't create new processes or hog resources.
Limit background processes from developer options
If you're looking for more aggressive control over everything running in the background, Android includes a global setting in the developer options for set a maximum number of processes allowed behind the scenesIt's a powerful tool, but it's best not to touch it without knowing what it entails.
The path to this option is usually: activate the developer menu, access it from the settings, and scroll down until you find "Limit background processes" (The exact name may vary depending on the brand.) When pressed, the system offers several levels, from standard mode to very restrictive values.
Among the alternatives, the adjustment of do not allow any background processesThis means that as soon as you exit an app, Android closes it completely and leaves nothing active. It's a very drastic measure that's only reasonable in specific situations, for example, when your battery is low and you need to maximize it, even at the expense of some convenience.
You can also choose to keep a very small number of processes running in the background (one, two, three…). This way, The apps you use least will close sooner than usual.while those you open frequently will try to be stored in memory as long as there is room.
The major drawback of this system is that This applies equally to all appsIt doesn't let you decide on a case-by-case basis which new app you want to keep running (for example, a stopwatch like Forest) and which one you'd prefer to close as soon as you exit it. It's useful for cutting battery life, but it sacrifices a lot of fine-tuning.
If at any point you regret having touched it, simply Go back to the same section and select "Standard Limit"From that point on, Android will resume its default behavior in managing processes and memory.
Battery optimization and automatic Android restrictions
With the latest system versions and the arrival of features like Doze, Android has become much more aggressive in analyzing your usage and applying automatic restrictions to background activityThis directly affects newly installed applications, especially if you barely open them.
On almost all modern mobile phones you'll find a section for Battery, Energy Saving or Device CareInside, you'll often find options like individual app optimization, lists of apps with adaptive restrictions, and power-saving modes that cut background tasks when the battery drops below a certain percentage.
To manage a new app that's getting out of hand, the usual thing to do is go to Settings > Applications, enter its information and Look for the "Battery" or "Battery Usage" subsectionFrom there, most manufacturers allow you to choose between modes such as "Optimize", "Severe Restriction" or "No Restrictions", which influence how much their activity is limited behind the scenes.
In other models it's done the exact opposite: from Settings > Battery you can Open a list of applications and decide which ones will have active optimization.Some manufacturers also add options for «hibernate apps", so that the selected ones freeze completely when you turn off the screen and only wake up when you open them manually.
These features have a huge advantage: They automate the control of the applications you use least.The system learns what you usually open daily and what gets forgotten, so newly installed apps that you hardly ever touch end up being punished with less time to run in the background.
However, each brand implements this type of cost saving in its own way. Some interfaces (such as EMUI, MIUI, ColorOS, realme UI, or certain versions of One UI) They are so aggressive that they end up closing apps that you want to keep active.such as FTP servers, Forest-type study apps, or monitoring tools. In these cases, you usually have to manually review lists like "Not Optimized Applications," "Apps That Never Sleep," or "Applications Always in Sleep" and exclude the ones you need to keep running.
Fine control: close, uninstall, or disable specific apps
Beyond global adjustments, the ideal is often act only on a handful of specific appsThese are usually newly installed apps that have proven to be too resource-intensive. You can manage them quite precisely from Settings > Applications.
On each app's page, you always have the button to "Force stop" to shut it down completely. when it's consuming more resources than it should. If after observing it for a while you discover that it doesn't contribute anything, the next logical step is to click "Uninstall" and remove it from the list.
With system applications or those pre-installed by the manufacturer, there is usually no uninstall button, but Yes, there is a "Disable" option.By doing so, they disappear from the app drawer and stop running and updating, as if they didn't exist for all practical purposes.
On some devices (especially with versions like Android 10, 11, or 12) you'll see shortcuts from the battery menu to to ensure that certain apps actually stop when you close themSometimes it appears under names like "Application Hibernation", "Power Management", or "Aggressive Optimization".
By combining these options you can decide which newly installed apps have free rein to continue working in the background (for example, your messaging app or email client) and which ones are only activated when you open them. However, it's best not to hibernate or excessively restrict services that you need to notify you instantly.
The role of third-party apps in hibernating applications
If everything that Android offers out of the box isn't enough for you, you have the option of installing third-party applications specialized in hibernating or freezing other appsThey are especially attractive to advanced users or those who frequently change their mobile phone and want to have everything very well controlled.
One of the best known is Greenify. For years it was almost mandatory for those with rooted phones, and over time It has been adapted to also work without root in many tasks. Its philosophy is simple: detect which applications are consuming resources in the background and offer you a quick button to put them to sleep.
The usual procedure involves granting certain permissions (device administrator, accessibility, etc.), indicating whether your device is rooted or not, and Add to a list the apps you want Greenify to hibernateincluding newly installed apps. From then on, the tool suspends them every time you turn off the screen or after a period of inactivity.
Another veteran in the root world is Titanium Backup, more geared towards back up and freeze applications you don't want to runThe concept is similar to disabling them from the settings, but with more flexibility to restore them or move them between devices.
Even so, it's important to understand that these types of solutions aren't essential for most users. With Android's improved automatic management and battery and developer menus, Most users can control background apps without installing anything extraThird-party tools are more of a bonus for those who want to get the most out of the configuration.
When is it worth closing background apps, and when isn't it?
After seeing all these options, it's easy to fall into the temptation of Close absolutely everything that moves in the backgroundEspecially if you've just installed several new apps and are suspicious of them all. But it's not always the best idea.
Android is designed so that many applications remain partially loaded. Therefore, Reopening them consumes fewer resources than starting them from scratch over and over again.If you obsess over forcing apps you use often to stop, the system will have to work harder to restart them, which can ironically lead to increased battery drain.
On the other hand, there are applications that only make sense if they can run in the background: Instant messaging, email, social networks, banking apps with alerts, study timers, or file serversIf you over-block them, you risk missing important notifications or having long tasks (like an overnight FTP backup) interrupted. If you need to maintain services like these, see how Use your mobile phone as a secure file server.
Ideally, a balanced approach should be applied, focusing primarily on Newly installed applications that do not need to be permanently activeIf you try a shopping, coupon, or one-off task app and find that it keeps running in the background, it's a good candidate for restriction or removal.
It's also important to understand that if your phone is overloaded with bloatware or has limited hardware, simply closing processes won't work miracles. Often, it performs better. Uninstall or disable what you don't use, check for system updates, or even consider a factory reset when performance is disastrous.
Being mindful of what runs in the background, especially among newly installed apps, is similar to keeping your house tidy: You don't have to be tidying up all the time, but it is a good idea to do regular cleaning and decide what stays and what goes. so that the phone runs smoothly, the battery lasts, and notifications are just right.
