Telephone running slow? Use Android's built-in RAM manager to free up memory «Android :: Gadgethacks



Nowadays there are telephones with 12 gigs of RAM, but they will cost you more than a cent. Most Android devices have much less memory – I think most have less than 4 GB. And with the system that takes up around 2 GB, which means apps installed by the user have little room to breathe.

Earlier in the history of Android, people tried to solve this with RAM managers (apps that allow you to close other apps to free RAM). Ironically, this would only use more system resources because the apps would simply be reopened after they were closed. But now Android has its own built-in RAM manager, and it can help you free up memory if used correctly.

Step 1
: Unlock Developer Options

The RAM manager is in the Android Developer Options menu, which is hidden by default. To unlock it, go to Settings -> About Phone and then quickly tap "Build Number" seven times. If you need more help with this section, view our full guide below.

Step 2: Manage your RAM

Now open the Developer Options menu. For most people this is shown at the very bottom of the main Settings menu. For newer Android versions you may need to go to Settings -> System -> Advanced to find it. Once inside, select "Running services", which should be at the top of the list.

You will now see all active services. Services are components of apps that perform operations in the background (for a longer period of time) without a user interface. For example, services process RCS messages. They usually work perfectly without ever having to communicate with them or even being aware of their existence. However, you may come across a problem every so often, especially if you have limited RAM.

Here you can stop the operation of each service or report it if you encounter a problem. By default, apps are organized based on RAM usage in descending order. If you notice that your phone is slow, we recommend that you do not stop processes randomly. The app reopens seconds later and beats the target. What we do recommend is to use the data provided to better manage your app selection.

After analyzing the graph at the top, check if there is little RAM. If about 1/3 of your total RAM is free, you probably have no RAM problem and you have to search elsewhere. If you have less available RAM, view the list of apps with the highest RAM usage for services. Do you need these apps? If you do not, you must uninstall the installation.

If an app uses too much RAM, you may need to remove it now until you upgrade your phone or the developer pushes an update to reduce RAM usage. For smartphones with less than 4 GB of RAM, you must be selective which apps will stay on your phone if you want smooth performance.
