你的手机变慢了吗？你需要经常给手机充电吗？你是否觉得你的手机没有以前那么流畅了？如果您对这些问题的回答是肯定的，那么您需要终止在后台运行的Android应用程序。(Android)随着时间的推移，Android设备往往会变得迟缓。电池开始快速耗尽。即使是触摸响应也感觉不是很好。这一切都是由于没有足够的RAM和CPU资源造成的。
手机变慢的主要原因是后台应用程序。使用完特定应用程序后，您将退出它。但是，该应用程序继续在后台运行，在消耗RAM的同时也消耗了电池电量。这会对您的设备的性能产生负面影响，并且您会遇到延迟。如果设备有点旧，问题会更加突出。但是，这并不意味着您现在需要更换手机。有很多不同的方法可以杀死后台运行的应用程序并提高设备的性能。在本文中，我们将详细讨论其中一些对您非常有帮助的解决方案。
如何杀死在后台运行的 Android 应用程序(How to Kill Android Apps Running in the Background)
1. 从“最近”选项卡关闭后台应用程序(1. Close Background Apps from the Recents tab)
杀死后台Android应用程序的最简单方法是将它们从最近的应用程序部分中删除。这是清理RAM以延长电池寿命的一种非常简单的方法。请按照以下步骤操作：
1. 打开最近的应用程序部分。(recent apps section.)对于不同的设备，这样做的方法会有所不同。它还取决于您使用的导航类型。它可以通过手势、单个按钮或标准的三按钮导航窗格来实现。
2. 完成此操作后，您可以看到后台运行的不同应用程序。(different apps that are running in the background.)
3. 现在滚动浏览这些应用程序的列表，然后选择您不再需要(select the app that you no longer need)并想关闭的应用程序。
4.只需(Simply)将应用程序拖到顶部即可将其删除。关闭应用程序的最后一步可能在您的手机上有所不同。您可能在每个应用程序窗口的顶部都有一个关闭按钮，您需要按下该按钮才能关闭应用程序。您也可能需要将应用程序滑向不同的方向。
5. 如果您有“全部清除”按钮或垃圾箱图标，您也可以一起删除所有应用程序，只需单击它即可。
2. 检查哪些应用正在耗尽您的电池电量(2. Check Which Apps Are Draining Your Battery)
为了正确识别哪些应用程序导致系统变慢，您需要检查电池(check your battery)消耗日志。这将准确告诉您每个应用程序消耗了多少电池。如果您发现某些应用程序消耗电池的速度比其他应用程序快得多，那么您可以轻松阻止它们在后台运行。这是一种有效的诊断方法，可让您发现罪魁祸首。请按照以下步骤检查哪些应用程序正在大量消耗您的电池。
1. 进入手机设置(Settings)。
2. 现在点击电池选项(Battery option)。
3. 之后，选择电池使用(Battery usage)选项。
4. 您现在将能够看到应用程序列表及其功耗。(list of apps along with their power consumption.)这将帮助您确定需要关闭哪些应用程序并防止其在后台运行。
您可以通过多种方式阻止这些应用程序运行。我们将在本文的以下部分讨论这些方法。

Is your phone getting slow? Do you need to charge your phone often? Do you feel that your phone isn’t working aѕ smoothly as it used to? If you answered yes to these qυestions, then yоu need to kill Android apps running in the background. Over time, Android devices tend to get ѕluggish. Thе battery starts draining out quickly. Even the touch resрonse does not feel great. All this is caused by the υnavailability of enoυgh RAM and CPU resources.
The main reason behind your phone getting slow is background apps. When you are done using a particular app, you exit it. However, the app continues to run in the background, consuming RAM while also draining the battery. This negatively affects the performance of your device and you experience lags. The problem is more prominent if the device is a little old. However, it does not mean that you need to replace your phone just yet. There are a lot of different ways to kill apps running in the background and improve the performance of your device. In this article, we are going to discuss in detail some of these solutions that will be very helpful for you.
How to Kill Android Apps Running in the Background
1. Close Background Apps from the Recents tab
The easiest way to kill background Android apps is by removing them from the recent apps section. It is a very easy method of clearing up RAM to make the battery last longer. Follow the steps given below:

4. Simply drag the app towards the top to remove it. This last step to close the app may be different on your phone. You might have a close button on top of each app window that you need to press in order to close the app. It is also possible that you might have to slide the apps in a different direction.
5. You can also remove all the apps together if you have a ‘clear all’ button or a dustbin icon by simply clicking on it.
2. Check Which Apps Are Draining Your Battery
In order to properly identify which apps are responsible for slowing down your system, you need to check your battery consumption log. This will tell you exactly how much battery is being consumed by each app. If you find out that some apps are draining the battery much faster than others, then you can easily stop them from running in the background. This is an effective diagnosis method that allows you to detect the culprit. Follow these steps to check which apps are vigorously consuming your battery.
1. Go to the Settings of your phone.
2. Now click on the Battery option.
3. After that, select the Battery usage option.
4. You will now be able to see the list of apps along with their power consumption. This will help you to figure out which apps need to be closed and prevented from running in the background.
There are many ways in which you can stop these apps from running. We are going to discuss these methods in the following section of this article.

5. Once you find it, simply click on it.
Now you will find the option to Force Stop the app. You can also choose to uninstall the app if you feel like.
4. Stopping Apps by Using Developer Options
Another way to stop apps from running in the background is by stopping them from developer options. Developer options are originally unlocked on your phone. In order to use them, you first have to enable developer options. To do so follow the steps given below:
1. Firstly, open the Settings on your phone.
2. Now click on the System option.
3. After that select the About phone option.
4. Now you will be able to see something called Build Number; keep tapping on it until you see the message pop up on your screen that says you are now a developer. Usually, you need to tap 6-7 times to become a developer.
Once you have unlocked the developer privileges, you can access the developer options to close apps that are running in the background. Go through the steps given below to learn how to do so.
1. Go to the Settings of your phone.
2. Open the System tab.
3. Now click on the Developer options.
4. Scroll down and then click on Running services.
5. You can now see the list of apps that are running in the background and using RAM.
6. Click on the app that you wish to stop running in the background.
7. Now click on the stop button. This will kill the app and prevent it from running in the background on your Android phone.
Similarly, you can stop each and every app that is running in the background and consuming memory and power resources.
5. Updating your Android System
Another effective way to improve the performance of your device and increase its battery life is by updating your Android operating system to the latest version. With each update, the Android system improves its phone optimization features. It comes with better power management features that automatically close the background apps. It speeds up your phone by clearing up your RAM which was earlier occupied by apps running in the background.
If it is possible, then we would recommend you upgrade to Android Pie or higher versions. One of the best features of Android Pie is the Adaptive Battery. It uses machine learning to understand your mobile usage pattern and figure out which apps you use frequently and which apps you don’t. This way, it automatically categorizes apps depending upon their usage and assigns fixed standby times, after which the app is stopped from running in the background.
Follow these instructions in order to update your device:
1. Tap on the Settings option on your phone and select System or About device.
2. Simply check if you have received any new updates.
Note: When the updates are being downloaded make sure you are connected to the Internet using a Wi-Fi network.
3. If yes then put it on Download and wait until the installation process to complete.
6. Using the In-built Optimizer App
Most of the Android devices have an in-built optimizer app. It automatically clears RAM, stops background apps, detects junk files, clears unused cache files, etc. It can also improve battery life by optimizing various phone settings. Follow these steps to improve the performance of your device using an optimizer app:
1. The optimizer app should be on your main screen or the app drawer. It can also be a part of the system tools provided by the manufacturer. Once you locate the app, click on it.
2. Now simply click on the optimize option.
3. Your phone will now automatically stop background processes and take other steps required in order to improve battery life.
4. In the end, it will even provide a comprehensive report of all the things that it did in order to optimize your device.
7. Use a third-party app to Optimize your Android device
If your device does not have a decent in-built optimizer app, you can always download one from the Play Store. There are hundreds of apps to choose from. These apps will constantly detect unused background apps and close them. They even provide an on-screen widget to close all background apps in a single click. One such app is Greenify. It allows you to monitor the memory and power usage of different apps and then place them in hibernation. In order to make the best use of the app, you can also root your phone and give the app root access.

The only contention with third-party apps is that they are continuously running in the background themselves to detect and close other apps. This is sort of counter-productive. The best way to decide is by installing the app and trying it yourself. If you see that it is further slowing down the device, then go ahead and uninstall it.
