I believe many friends have heard of the tombstone mechanism of iOS, right? The

mechanism can record the status of these apps like tombstones when we switch them to the background, and then freeze them so that they will not compete with the foreground apps for CPU resources.

When we switch back to App , it will restore the App to the state before freezing based on the records on the tombstone; if the App hangs for a long time, it will further release memory to reduce power consumption and heat generation.

It can be said that a large part of the reason why the iOS system is so smooth is due to the tombstone mechanism. This is also the reason why iPhone 13 is still using 4G memory today in 2022.

When I was leisurely visiting Coolan recently, accidentally discovered that Android can actually implement a tombstone mechanism similar to iOS:

And according to feedback from Coolan fans, after turning on the tombstone mechanism in Android, the effect Surprisingly, many people said that the heat and power consumption of mobile phones were reduced a lot with , and the phenomenon of killing the background was not so serious:

Out of curiosity, Shichao also tried it on his own mobile phone, and unexpectedly it had an effect.

Before turning on the tombstone mechanism, I opened WeChat, Weibo, Baidu Maps, WeChat Reading and other Apps in the background of my mobile phone. You can see that even in the background, they still occupy part of the CPU resources:

And in After I turned on the tombstone mechanism, the CPU usage of these apps that had been hung in the background suddenly became 0%. The effect can be said to be immediate:

Of course, this situation is not absolute.

While continuing to open other apps, I noticed that sometimes some apps may have one or two processes that continue to occupy the CPU. only takes up a very small proportion, basically below 5%:

These backgrounds After the CPU resources of the app were released by , the most obvious thing I felt about was my mobile phone. I opened multiple apps at once and finally stopped getting stuck, and the phone did not get very hot during the whole process!

Before, as long as or opened seven or eight apps in a row, the system would experience frame drops and freezes, and the phone would start to heat up. When I opened more than ten apps, the gesture operations would become inconsistent. hand.

But having said that, turning this feature on is not without its disadvantages.

Some people reported that in instant messaging software such as WeChat, even if you hang it in the background when a message arrives, you may not receive messages or messages may be delayed; some apps may pause downloading files when switching to the background.

Actual measurement shows that after setting these Apps to auto-start, it seems that this problem can be avoided. At least my mobile phone has not encountered the previous two situations. As soon as the news comes, the CPU usage of WeChat will increase immediately:

In short, I suggest that you are Friends who use Android phones can try it on their own. If they feel that it has little effect or affects the experience, they can just turn it off again.

Next, Shichao will tell you how to enable the tombstone mechanism on Android phones.Before turning on

, we need to enter the phone settings to find the system version number, click the version number multiple times until the system prompts "You are already in developer mode", and then enter the developer options page:

In the developer options, We need to find the option "Pause execution of cached applications". After selects it to be enabled, restart the phone, which is equivalent to turning on Android's tombstone mechanism:

If you do not find this option in the developer options of your phone, For , it is most likely because the manufacturer has blocked this function in the system. At this time, we need to use third-party tools to enable it.

It is a little troublesome to enable the tombstone mechanism with a third-party tool. First, we need to download a wireless debugging tool Shizuku from Coolan, and then activate Shizuku according to the tutorials and tips provided by this App:

After the activation is successful, we also need to download a wireless debugging tool Shizuku from Coolan. Aiwanji Toolbox, and grant the corresponding permissions to this software:

. Among these permissions, we can directly authorize the basic permissions.

The "Modify System Security Settings" permission requires Shizuku to be authorized successfully. If you have activated Shizuku, just click "Shizuku" in the lower left corner:

Then you can set up the system related settings of the Aiwanji Toolbox Find the " pause execution of cached application " option, select " start at any time", restart the phone and you're done:

In general, I personally feel that Android is quite open, giving us such a Since there are options, we might as well give it a try. Maybe there will be unexpected surprises. Thank you everyone for watching!
