Android phone 6GB memory for a long time or the card is what's going on Android Big Memory for a long time why will the card

A TSMC 10nm technology gradually mature, Gaotong 835, MediaTek Helio X30 and Kirin 970 are their customers, so that mobile phone performance is expected to blowout again. However, CPU and GPU performance up, memory can not drag it? No 8GB memory, who has the nerve to match the next generation of processors?

By the way, in addition to these new flagship processors, existing processors like Xiao 821 and 653 have added support for 8GB of memory, so the 8GB memory handsets should be available sooner than we expected. So where is the 8GB phone memory?

8GB mobile phone memory will be mass production

2 months ago, Samsung released the industry's first 8GB LPDDR4 DRAM, its entire four 2GB (16Gb) particles, 10nm (10nm~20nm) process manufacturing, with 20nm-level 4GB similar packaging area (stereo measurements 15mmx15mmx1.0mm ) and power consumption.

Not long ago, SK Sea also quietly completed a new generation of 8GB LPDDR4 memory, the chip by the 21NM process manufacturing, the same integration of four 2GB (16Gb) particles, using 15mmx15mm FBGA small package design.

In general, Samsung's 8GB mobile phone memory specification is better than SK Heidelberg (mainly 10nm process output), but this and our consumer relationship is not big, in the end with who still have to see the cost of mobile phone manufacturers budget.

8GB memory useful?

Well, it's time for a cliché. When the 2GB changed to 3GB, 3GB to 4GB, 4GB changed to 6GB when all experienced a similar discussion: The greater memory in the end is a gimmick or really necessary? Let's take a look at how popular apps are hungry for memory.

No idea, huh? Many mainstream app own peak memory usage exceeds 500MB mark, this means 2GB memory can only open 4 at the same time, 3GB memory is 6, 6GB memory is 12, even 8GB memory can only run 16 at the same time? From this point of view, the larger the memory nature is better, don't say 8GB , even 12GB, 16GB is not too much!

Why can the old mobile phone also very fluent?

The problem is, the vast majority of Android phone memory is still in the 3GB or 4GB stage, why these phones can still run in the background at the same time dozens of programs still fluent?

The reason is simple, the Android system itself with a set of relatively mature memory scheduling mechanism, we can interpret it as "the lowest elimination." The Android system will have all system-level apps (such as time, system input method) and third-party apps (such as micro-letters, games) prioritization, when the remaining memory is not enough to meet the current startup program requirements, the system will automatically turn off the priority of those app and related processes.

For example, your mobile phone is running at the same time micro-letter, microblogging, QQ, the United States, Taobao, Beijing east, the weather of these 7 apps, at this time the memory occupancy rate of 80%. When you want to play "King Glory" game, in the moment you click the game icon, the system will automatically determine the running "King Glory" required memory resources. For example, the game requires 50% of the memory, according to the "final elimination" mechanism, such as the United States Regiment, Taobao, Jingdong, some of the non-Instant messaging app will automatically be closed, and then will officially start the "King Glory" this game.

Therefore, when we exit a game, press home to switch to the background to run the program will sometimes revert to the previous window state, but sometimes the program will restart. And the following situation, is the system in order to ensure that the game runs, automatically shut down the background running this program, will release the memory for the game to start up.

In addition, when many apps go backstage, they enter a sleep-like state, where the consumption of the memory becomes lower until the foreground is awakened before the ram begins to crush.

In addition to the official Android memory scheduling mechanism, many mobile phone manufacturers have added a more reasonable system level of program management mechanism, such as the so-called "pure background" "screen cleaning" and other functions, that is, when the mobile phone into standby, automatically clean up the non-white list of all programs, Always keep the memory in a stable capacity for a rainy month.

In theory, with the Android and the manufacturer's two "insurance", 2GB memory may be a bit, but 3GB memory mobile phone should not be running multiple apps and change card. However, the reality is that even if the 4GB or even 6GB memory phone, sometimes there will be Ka Chengxiang phenomenon, which is swollen again?

Why do 6GB memory phones sometimes get stuck?

Although short, but all very incisive.

In fact, the reason that really causes the Android system to slow down is still reflected in the current app application environment and the user's usage habits.

App Application Environment back cauldron

Since the domestic Android phone does not have a unified application publishing platform (Google play is not available at home), and Third-party app stores often and app developers to reach a tacit understanding, so any one app can bundle a variety of ads, push a variety of services, eventually resulting in a "family bucket" phenomenon.

You have just opened an app, the background automatically triggered the app's family bucket package, the original 300MB memory can be solved, and suddenly became 500MB or even 800MB, mobile phone memory is big, also very easy to be filled with this mechanism.

In a word, the memory of the production, how bold people! If you dare to have larger memory, app developers will be willing to play a more high-end ad push, and the various wake-up developers will not have to optimize.

Personal use habit back small pot

For the wake of the app and the family bucket problem, many handset vendors have added the related management function to the system. However, not all children's shoes are known, or will be used.

So, a 4GB memory mobile phone someone to use it very handy (not card), but a 6GB memory mobile phone in some people can be used to Kachengdo (such as always through the home key "Exit" program, allow all app to send notice also never clean up, not card etc?)).

So, the memory is not enough, and the user's level of playing a certain relationship, for ordinary users, larger memory can reduce the chance of the advent of the card. From this point of view, larger memory is still meaningful.

In short, the domestic Android system does not have a unified and perfect app download channels, not strictly for rogue app audit and the next system, any memory of your big, there are cards into a dog day.

Looks like a tragedy? No way, that's the truth.

The good news is that 8GB of memory can be fast from the advent to the popularity of domestic Android handsets. For high-end mobile phones in the 2017, 8GB of memory may be useless (for gamers), but you can't do it as a mobile phone.

Let's celebrate the mobile phone into the 8GB memory era, perhaps more memory is useless to you, but at least let more people do not know how to optimize the mobile phone system methods and principles, but also can be used more smoothly and smoothly. Besides, at this time of next year, the price of 8GB memory phone will also be as cheap as 6GB or even 4GB memory now.
