An old question: who is better to use iPhone and Android? Different users must have different views on this. A few years ago, there might have been more users on the side of IOS. Thanks to the good scheduling of IOS, iPhone is synonymous with silky and smooth. With the continuous improvement of the hardware configuration of Android phones and the addition of high screen swiping, the fluency of today's Android phones is not inferior to that of iPhone. While improving fluency, a phenomenon that can not be ignored is that Android phones have more and more memory, but users' memory anxiety has not been alleviated at all. Why do Android phones, which have much more memory than the iPhone, always worry about memory? The iPhone needs 8g of memory The first is to explain a problem that can fill the blood pressure of digital practitioners and enthusiasts: memory and storage. Memory usually refers to ram, namely "random access memory", which is the internal memory that directly exchanges data with CPU, similar to an intermediary between CPU and storage, commonly known as "running memory". Storage refers to ROM, or "read only memory", which usually refers to the memory hard connected to the computer, and its contents will not disappear when the power is turned off. What we call memory today is the former of the two (RAM). Jeff Pu, a well-known analyst, published a report last December, predicting that the iPhone 14 pro and pro Max will be upgraded from 6GB memory to 8GB in 2022, and the iPhone 14 and max of non pro models will be upgraded from 4GB to 6GB. In February this year, a post on South Korea's naver blog expressed the same view. The news came from the supply chain. Some sources also expressed different views. For example, analyst Guo Mingzhen believed that the iPhone 14 will be equipped with 6GB memory as standard. 8GB is the peak of iPhone memory configuration. Although the performance of iPhone is becoming more and more powerful, it is not like the iPad to play the productivity card after all. The maximum memory of the latter has come to 16GB of desktop PC level. Memory allocation is a direct comparison between apple and Android camp. With the blessing of IOS and ipados, the daily experience of iPhone with 4GB and 6GB memory is smooth, and the iPad pro with 8GB and 16GB even feels redundant (ipados is recommended to reflect); On the Android side, 4GB and 6GB memory are entry-level, 8GB and 12gb are becoming mainstream, and mobile phones use 16GB or even 18gb memory. We still think that more memory is better. How much memory will Android phones need in 2022? What are the advantages of large memory mobile phones? I believe readers know this clearly: running all kinds of large-scale games and Applications (large in various senses), opening more applications without killing the background, daily use without jamming, and so on. In other words, both heavy and light users need as much memory as possible. Straight to the point, how much memory does your Android phone need in 2022? Foreign media Android authority uses pixel 3 XL with 4GB memory, one plus 9 pro with 8GB memory and Samsung Galaxy S21 ultra with 12gb memory respectively, which correspond to the memory configuration of current entry-level mobile phones, medium and high-end mobile phones and flagship mobile phones. Figure from Android authority This test mainly adopts some international mainstream and large-scale games. The list and average memory occupation are as follows: Subway Parkour: 750mb Air force 1945: 850mb Candy legend: 350MB Wild fighting: 500MB My world mobile game version: 800MB Wild racing 9:800mb Shadow gun: Legend: 900mb Ancient scroll: Blade: 950mb Original God: 1.4GB Chrome browser: 2.2GB From the results, the Samsung Galaxy S21 ultra with 12gb memory can keep all games in memory. As the games are opened one by one, the free memory decreases gradually, and the utilization rate of swap space used to relieve memory pressure increases gradually, but no application is cleared. After joining Google Chrome and opening 12 tabs, a game was finally killed and needs to be reopened. 8GB one plus 9 Pro is slightly different. Because of the strict memory management mechanism, the system will clean up background applications when there is still memory left. After closing ramboost, one plus 9 Pro can open five games without killing the background. When opening the sixth game, the first game is killed. The 4GB pixel 3 XL is equivalent to the starting memory of today's domestic entry-level models. It can only reside in three games, which is a little tight today. Although this test basically does not participate in the mainstream "big application" in China, the average memory footprint of these mainstream games is comparable to that of WeChat and Alipay. Yes, with their increasingly rich functions, their memory consumption has also reached the level of large-scale games. According to the results, the simple conclusion is that 8-12gb Android phone is an ideal choice, 6GB is enough at present, and 4GB and below memory will be a little tight. 4GB iPhone is very smooth, and 4GB Android phone is very tight? In terms of memory, iPhone and Android phones are two landscapes. Although there are rumors that the iPhone 14 Pro Series Needs 8GB memory, mainstream models such as the iPhone 12 and iPhone 13 non pro series still rely on 4GB memory, and the current flagship iPhone 13 Pro Max memory is only 6GB. How does IOS do so many things with small memory? This involves the memory management mechanism of IOS and Android. Android system adopts a desktop level multitasking mechanism, which can be called "real background". On the contrary, IOS has almost no so-called real background and multitasking. When the iPhone was launched in 2007, its operating system only supported single task. In 2009, Apple Push Notification Service (APNs) was added to iPhone OS 3 (not called IOS at that time). Mobile phones can automatically receive information from software. This is a major milestone in IOS background mechanism, which can be regarded as a kind of senseless background. Because new smartphone users often don't know what background applications are. When they see notifications from various applications, they will feel that these applications are working normally. Not only iPhone users, Android users often judge whether the background application is normal or not according to the notification system. The two major milestones since then are iOS 4 and IOS 7. IOS 4 introduces a limited background, commonly known as the "tombstone" mechanism and "pseudo background". When you press the home key, you will record the status of the current application, and then continue to read files when you enter the application again. IOS 7 brings a background fetch, which becomes a limited real background. IOS has successively opened multiple interfaces for applications, such as location-based services and news push, so that applications can be updated in the background. The memory mechanism of Android system is much rougher. The inherent desktop level real background mechanism and Java's no exit design determine that Android applications can eat as much memory as they have. In this way, when applications are opened one by one, they will occupy more and more memory; When the memory is in emergency, the Android system will kill the process to free up memory space, and the person in charge of life and death is called low memory killer daemon. From the literal sense, the real background is certainly better than the fake background, but its negative effects can not be ignored: background applications occupy memory, consume unnecessary power and so on. The management mechanism of Android system determines that Android phones naturally need more memory. Google has introduced a variety of optimization mechanisms for the native Android system, such as the "doze" doze mode of Android 6.0. Last year, many domestic OEMs withdrew from the so-called memory fusion technology and allocated a part of the storage space to memory for capacity expansion. In fact, it is also a replica of Android native (to be exact, Linux native) zram and zswap functions. Our perception that Android phones consume more memory or power is mainly due to the impact of domestic special circumstances. Domestic applications wake up each other with the help of shared third-party push services, and often disguise as the front desk through various means to ensure storage, which brings unnecessary memory occupation and power consumption. Because there is no need to go through the strict review of Google play store, the official Google application store, domestic applications are always one foot higher than the devil. There are various ways to bypass the restrictions of Android native applications and eat the memory and power of the mobile phone. How much memory do you need to buy a mobile phone this year? In general, 8GB memory is ideal for Android phones in 2022, which can meet the resident needs of large-scale games and daily multi applications; 12gb can realize free memory, run large applications at will and open more at will; Mobile phones with 4GB memory are already quite tight. Users who choose such phones usually have a limited budget. We suggest moving to the level of 6GB memory as far as possible if allowed. Now, some major Android manufacturers (especially domestic manufacturers) have launched 16GB and 18gb memory, and some have come up with memory fusion technology, mainly taking advantage of the memory anxiety of Android users. Such a large memory is actually icing on the cake rather than providing timely help. Because of the marginal effect, the experience improvement they bring is not obvious. In contrast, 512gb and 1TB storage, which are often matched with large memory, increases the selling price of mobile phones. The famous Andy Beer law tells us that the hardware configuration required by application software will continue to improve. Therefore, we should not criticize those applications that eat more and more memory. The increasing hardware specifications of mobile phones are just to carry more and better functions. Although there are differences in memory between IOS and Android, the growth in memory demand of iPhone and Android phones is the same irreversible trend. However, application expansion should not be unlimited. Imagine the future. We hope to see a strong regulatory mechanism, a high degree of industry consensus and a sense of responsibility of software and hardware manufacturers. Only in this way can we eradicate all kinds of chaos of domestic Android phones. If we want to set a small goal for this wish, we hope that the unified push alliance will come early.
