Do You Need to Enable the Suspend Execution for Cached Apps on Galaxy S22 or Galaxy S21, S20, and S10 with Android 12 update?

Last Modified: August 6, 2022 · Leave a Comment

Do You Need to Enable the Suspend Execution for Cached Apps on Galaxy S22 or Galaxy S21, S20, and S10 with Android 12 update?

Galaxy S22 introduced the Suspend Execution for Cached Apps to minimize the battery usage of the cached apps. It was also added to Galaxy S21, S20, and S10 through the Android 12 update.

Do you know whether you need to enable the Suspend Execution for Cached Apps on Galaxy S22, or S21, S20, and S10?

The short answer is NO because It was already enabled by default.

This Galaxy S22 new features guide explains how the Suspend Execution for Cached Apps works and how to enable and disable Suspend Execution for Cached Apps on Galaxy S22, S21, S20, and S10 (with Android 12 update).

What is Suspend Execution for Cached Apps? How does it work?

Many Galaxy S22 owners want to maximize the battery life without sacrificing usage and convenience. Suspend Execution for Cached Apps is one of the new features in Android 12 to reduce the battery (and other resources) usage of most background apps.

What is Suspend Execution for Cached Apps?

The Suspend Execution for Cached Apps (Cached Apps Freezer) was actually first introduced in the Android 11 Developer Preview 3. But it was officially introduced as a new feature in Android 12, not in the final release of Android 11.

Samsung implemented this Suspend Execution for Cached Apps feature in their Android 12 builds (from One UI 4). So, in addition to Galaxy S22, you can also enjoy this feature in Galaxy S21, S20, and S10 after you update them to Android 12.

As suggested by the name, the Suspend Execution for Cached Apps freezes the cached apps so that these apps do not use any computing resources (and they normally should not except through some registered services), including CPU cycles. Therefore, the battery usage on the phone can be reduced.

How does Suspend Execution for Cached Apps work?

First, we need to understand what the cached apps are.

For example, you use Chrome to browse some websites on Galaxy S22. Then you return to the Home screen using the Home button or Back button (or corresponding navigation gestures) and use other apps. Now, the Chrome app is “cached” in the memory.

So, why not “close” (destroy) it?

The reason is simple: to re-launch it faster. The unused RAM is just wasted.

Because the app is NOT stopped, it can still use CPU cycles and network connections, e.g., check updates. Some third-party apps in this state may still use excessive resources. For example, the Facebook app may still track you silently even when you are not using it.

Google tried to force some apps to “sleep” to reduce the frequency of resource usage. But some apps may try to bypass it.

The Suspend Execution for Cached Apps goes one step further: it freezes the activities of these apps.

If the app needs to do something while in the cached state, it can still do it through registered services, which can be easily monitored by the OS. The “bad” services can be detected and suspended very quickly.

So, Suspend Execution for Cached Apps will not break most apps even if they require some legit background activities.

The benefits of the Suspend Execution for Cached Apps are:

  • Reduce battery usage.
  • Reduce data usage.
  • Lower the system load.
  • Re-launching the app is not affected.

Of course, for some very old apps, the background refresh and notification delivery may be affected.

Do I need to enable the Suspend Execution for Cached Apps on Galaxy S22, S21, S20, and S10?

The short answer is no because it was enabled by default on Galaxy S22, S21, S20, and S10.

The longer answer is you may try to re-enable it if you have any background battery drain issues (e.g., short screen-on time, SOT).

Please note, if Protect Battery is enabled, charging will stop once the battery level reaches 85%. This makes the SOT 15% shorter (but it should still be around 3-5 hours).

How to enable or disable Suspend Execution for Cached Apps on Galaxy S22, S21, S20, and S10?

As mentioned, on all Galaxy phones with Android 12, the Suspend Execution for Cached Apps feature is enabled by default.

But sometimes, you may try to re-enable it or disable it to check whether the cached apps caused some battery drain issues.

However, to enable or disable the Suspend Execution for Cached Apps feature, you need to enable and access Galaxy S22 developer options. Please follow this guide to enable it.

Once Galaxy S22 developer options are enabled, you can now scroll down to find the Suspend Execution for Cached Apps entry under the Apps group, as shown in the screenshot below.

Tap it to see the options.

enable Suspend Execution for Cached Apps

By default, it’s Default for this phone. It means it is enabled by default.

Of course, you can choose to re-enable it by tapping Enabled, It will then ask you to reboot the phone, as shown below.

You should tap OK to reboot the phone to re-enable Suspend Execution for Cached Apps

You can compare the battery life after one or two days to see whether the SOD increases.
