The reason for this is this. Recently, when Tony was free to browse Zhihu, he happened to brush up such an interesting question: increasing the memory can improve the experience, why doesn’t the iPhone increase the memory?
Don’t look at this question was first raised in 2019, but it is still not out of date in 2022.
Because whether it is the iPhone XS, 11, 12 or 13, their running memory has always started at 4GB.
At present, Apple has only four iPhones with 6GB of memory, and the cheapest iPhone SE 3 also has 4GB of memory, which is pitifully small compared to Android’s 8GB or even 12GB of memory.
And the answers to this question are varied.
Many people feel that the iPhone does not need to use large memory at all, because Apple has a dedicated server for pushing messages, which determines that even if the App is not hanging in the background, we can still receive their notifications normally.
However, various domestic Android manufacturers do not have a unified push service. The unified push alliance has not seen much progress for so many years. Until now, even national-level applications such as WeChat and QQ have not been connected to unified push.
This leads us to keep them resident in the background if we want to receive notifications of these apps in time. In order to ensure that the system can run smoothly after multiple apps are resident in the background, Android phones can only use larger memory.
You dare to believe that a single WeChat can occupy 1.2GB of memory ▼
Moreover, in order to save the cost of 10,000 yuan for the mobile phone, Guozi has cut off the charger and headphone adapter cable. If 4GB can make do with it, it will never give you 6GB, which can also shorten our replacement cycle.
Em. . . How to say it, I think what everyone said is quite reasonable. Tony is also curious about the difference between the iPhone with 4GB of memory and the iPhone with 6GB of memory.
So I specially found the iPhone 12 and iPhone 12 Pro, and I plan to test them to see if the extra 2GB of memory on the 12 Pro can make the difference with the 12 in terms of experience.
Before the official test, in order to eliminate the interference of other factors as much as possible, I have synchronized the data and applications of the two iPhones, cleared all the background and restarted them.
Let’s do a regular test first.
I opened a total of 10 apps on these two iPhones, and after the 10th app was loaded, I went back and randomly re-opened the app, and found that neither phone appeared to need to be reloaded.
So I opened 5 more apps, and they were still stress-free at this time. It was not until I clicked on 20 apps that the iPhone 12 finally couldn’t stand the pressure and reloaded the JD.com that I opened randomly:
On the other hand, when the iPhone 12 Pro opens JD.com, it is the previous page in seconds:
After repeated rounds of testing, I found that as long as the iPhone 12 opens more than 18 apps, there is a chance that a random app needs to be reloaded.
On the other hand, the iPhone 12 Pro has a stable batch even if it is opened to the 23rd app. If you click on an app at random, you can swipe directly on the page. Until the number of apps exceeds 26, I encounter a reload:
To be honest, the performance of the iPhone 12 has already surprised me. As a reference, I found an Android flagship with 12GB of memory and let it open the same app.
Unexpectedly, when this Android flagship opened to the 10th app, the transition animation had dropped frames and stuck.
When I opened the 18th App, although the system showed that there was 3GB of memory left, I had already encountered the need to reload the App to open, and the gesture operation was no longer followed at this time:
Guys, I was skeptical before when someone said that iPhone 4GB RAM can top Android 12GB RAM, and now I believe it. . .
Seeing this, some people will definitely say that the iPhone is a “fake background”.
The existence of the iOS tombstone mechanism allows foreground apps to monopolize memory, and those apps that have entered the background will be frozen by the system in some form, thereby releasing the memory resources they occupy.
And Android is “true background”, even if those apps are switched to the background, they will continue to remain active.
Since mobile phones of different systems cannot be compared fairly, let’s be realistic.
I have three apps, WeChat, Taobao, and Station B hanging at the same time in the background, and the front desk is playing the glory of the king. At this time, whether it is iPhone 12 or 12 Pro, I can seamlessly switch between these apps.
However, when I open the camera app and return to the glory of the king, the iPhone 12 already needs to be reloaded:
The iPhone 12 Pro can switch back to the glory of the king normally:
However, if you open the camera app and then press the shutter to take a photo, then the iPhone 12 Pro still has a certain chance to reload when it returns to the game:
And the Android flagship with 12GB of large memory, its performance is not even as good as the iPhone 12 Pro.
After opening the camera app, the phone can switch back to the game normally, but if you press the shutter button, then the Honor of Kings will most likely be reloaded. At the same time, the phone not only drops frames, but also freezes.
In this case, even if you forcibly lock the King of Glory App in advance, the system will kill the background.
In short, it is not difficult to see from the previous test that the iPhone 12 Pro with 6GB of memory will indeed be stronger than the 4GB iPhone 12 in terms of background App retention.
In addition, the iPhones with 6GB of memory are these three ▼
In fact, before I tested the Android phone with them, I thought that the Android flagship with 12GB of memory, its ability to keep apps in the background and hang the iPhone with half its memory should not be a problem.
However, the fact hit me hard in the face. You can’t accept the memory management of iOS. The Android flagship feels more like it is making up for its lack of experience by piling up crazy materials on the hardware.
In fact, Android is not incapable of implementing a tombstone mechanism similar to iOS.
As early as Android 6.0, Google enabled the system to support the tombstone mechanism from the bottom, but it still gave app developers a lot of freedom, allowing them to develop apps according to their own ideas.
It’s just that you all know what the domestic Android ecosystem is like.
It is nothing new for a large number of domestic apps to crazily occupy resources in the background and automatically wake up each other. Without coercive measures, those rogue app developers can consciously abide by the rules and not mess around.
But then again.
The open development space of Android is not all bad. It is because of its openness that we can use various apps like Li Tiaotiao and Wallpaper Engine on Android phones.
If nothing else, Android alone allows me to freely choose to lock one or more apps, thereby preventing these apps from being accidentally killed by the system, which is enough to keep me on Android. Thank you for watching!
