What applications are unloaded from RAM

Based on this, we can conclude that a smartphone with 4 GB of RAM will not hold more than three similar applications in memory. And if you upload, you may lose unsaved data.

Some phones will unload apps in chronological order. That is, the one that has not been used for the longest time will be the first to go. But some operating systems may be more gentle with memory. For example, OnePlus offers a RAMBoost feature . It analyzes your usage and tries to keep apps you use frequently in memory and kills apps you rarely use. It can even load apps into RAM if it thinks you'll be using them soon. But this function can be disabled, because applications are often closed when there is still enough space in the RAM.

When choosing a phone, think about how much RAM you need.

Three-channel DDR-3 memory kits, which are offered by all leading manufacturers as a component of Core i7-based systems, have a capacity of 3 x 1 GB or 3 x 2 GB. In the latter case, to work with the entire amount of RAM, you must use 64-bit software, while 3 GB of memory can also be used by a 32-bit operating system. Many of you have probably wondered whether 6 GB of memory is now in demand for everyday tasks like gaming. We are not currently considering the server segment and traditionally resource-intensive graphics processing tasks - for them, the more memory, the better. Corsair, meanwhile, released an interesting document (1.05 MB, PDF), in which it examined the gain from increasing the amount of RAM from 3 to 6 GB in games. We used Dominator memory kits of DDR3-1600 type (8-8-8-24), which operated in the Asus P6T Deluxe (Intel X58) motherboard at a voltage of 1.65 V. The Core i7-965 Extreme Edition processor operated at its nominal frequency of 3.2 GHz, two GeForce GTX 280 video cards in SLI were operated at a resolution of 1680 x 1050 and maximum quality settings. The operating system was the 64-bit version of Windows Vista SP1.

The test results are shown in the histogram. In Crysis Warhead, the minimum scene refresh rate tripled when moving from three to six gigabytes of memory. In other games, the increase in this indicator is much lower. It should be noted that the average scene update rate does not increase that much - from a fraction of a percent to 10% in Warhammer Online, and up to 19% in World In Conflict. Corsair also notes an increase in level loading speed of 12-23%.

Colleagues from the VR-Zone website conducted a similar study using a different method. The Core i7-920 processor was overclocked to 4.0 GHz; for comparison, Kingston DDR3-1800 memory kits of 3 x 1 GB and 3 x 2 GB were used, respectively. Radeon HD 4870 X2 and Radeon HD 4650 video cards were tested at higher resolutions such as 1920 x 1200 or 2560 x 1600. The results were much less optimistic than in the case of Corsair’s “home-grown” tests - the increase in performance in games from increasing the amount of memory barely reaches tenths fractions of a percent. Cases, as they say, can happen in all sorts of ways, but it is still premature to insist on a mandatory increase in memory capacity from 3 to 6 GB. For gaming, it is better to spend your available funds on a more powerful video card.

Which phone with 6 GB RAM is better to buy?

A large amount of RAM today is not just a marketing ploy, but a real necessity. However, even this will not protect against frequent unloading of applications from the RAM if the manufacturer did a poor job with optimization. But this does not apply to the smartphones presented in our rating. The review of smartphones with 6 GB of RAM included two excellent phones from Xiaomi, and the same number of Samsung devices. Huawei is represented by a total of 4 models (including solutions from the Honor sub-brand), because the capabilities and quality of Chinese phones are much better than those of its main competitors.

The best smartphones with 6 GB RAM

Especially for demanding users, for whom every detail in the device is important, a list has been compiled that contains the best smartphones with 6 GB of RAM. They have very good characteristics and are capable of performing various tasks. In addition, there are much more positive reviews from the owners of these gadgets than negative ones. The leader rating will help you choose a smartphone with 6 GB of RAM that will fulfill all the user’s desires.

Huawei P30 6/128GB

Last year's flagship from Huawei remains a relevant purchase even today. Unlike the current devices of the Chinese giant, the smartphone has not lost Google services, which guarantees users access to all the features of the Android system. Reviews praise the smartphone for its excellent camera, which remains one of the best on the market today. The P30 hardware platform is also good, and it’s hard to think of a task that the combination of the Kirin 980 processor and Mali-G76 graphics couldn’t handle. The phone turned out to be relatively compact (width 71.36 mm). The fingerprint scanner is located under the screen. It's quite accurate, but too fast. The smartphone can also boast certified protection against dust and moisture, but only according to the IP53 standard.

Advantages:

32 MP front camera;
excellent ergonomics;
autonomous work;
convenient EMUI shell;
charging speed;
excellent performance;
metal frame.

Flaws:

lack of stereo sound;
slippery glass body.

Xiaomi Poco X3 NFC 6/128GB

Xiaomi has always been able to surprise with impressive characteristics at a modest price. A smartphone with 6 GB of RAM and a powerful battery from the Poco sub-brand is the best proof of this. For the 20 thousand that the X3 model costs, you can hardly find something more interesting. For example, the IP53 protection degree is also declared here, and the camera with a 64 MP main module takes excellent photos. There is also an NFC module and even IRDA.

An important advantage of the Poco X3 smartphone over its competitors is its 5160 mAh battery. His phone lasts for 2-4 days of work (depending on the load).

Performance here is also excellent. Of course, the Snapdragon 732G chip with the Adreno 618 graphics accelerator does not reach the level of the Kirin 980, but it is enough for both applications and games. Poco X3 also boasts a top-notch 6.67-inch screen. Moreover, it pleases not only with excellent color rendition and high brightness, but also with a refresh rate of 120 Hz! The fingerprint scanner in the smartphone is on the right side.

Advantages:

cool main camera;
display refresh rate;
productive filling;
contactless payment;
128 GB of permanent memory;
fast fingerprint scanner;
huge battery.

Flaws:

the phone collects fingerprints a lot;
quite weighty.

Huawei P40 Lite 6/128GB

If you are ready to tinker with installing Google applications or are completely satisfied with what the AppGallery store offers, then the P40 Lite model from the same Huawei company would be an excellent choice. The rear camera here is almost as good as the phone described above. The P40 Lite's screen is slightly larger (6.4 inches versus 6.1). Its resolution is also Full HD+.

The Kirin 810 processor is responsible for computing in the inexpensive Huawei smartphone. It is slightly inferior to the 980 in terms of graphics and computing, but is better in terms of energy efficiency. Together with a 4200 mAh battery, this allows you to achieve excellent autonomy. I was also pleased with the charging speed (from 0 to 100% the battery fills in just over an hour).

Advantages:

attractive price tag;
good autonomy;
combination of price and functionality;
high charging speed;
smooth interface;
good sound in headphones;
matrix color rendition.

Flaws:

Google services are missing;
The kit does not include a cover.

Xiaomi Redmi Note 8 Pro 6/128GB

Immediately after its release, Redmi Note 8 Pro became a real bestseller. And even today it is happily bought by people who want balanced characteristics at a reasonable cost. The camera in this smartphone is similar to the modules installed in Poco X3. The battery is a little smaller (4500 mAh), but it lasts just as well.

The smartphone with 6 GB of RAM received the Helio G90T as a processor. This is one of MediaTek’s best developments, which is recognized even by opponents of this chipmaker. Redmi Note 8 Pro also boasts a reliable glass and metal body, an IR port for controlling equipment, and an NFC module for contactless payments.

Advantages:

cool large display;
build quality and design;
battery life;
fast fingerprint sensor;
good main camera;
thoughtful MIUI shell;
infrared port and NFC.

Flaws:

presence of advertising in the system.

Honor 20s 6/128GB

An excellent model from the Honor brand, which can be recommended to young people who are undemanding in terms of characteristics. This smartphone has a stylish appearance. Its body is available in classic white, as well as midnight black and blue-violet colors. The latter looks especially good, so it’s worth choosing this option.

The smartphone is equipped with a 6.15-inch IPS matrix. This is one of the best displays we have seen in devices up to 17-18 thousand rubles. The hardware here is modest, but it is enough for stable operation of the system, applications and even some modern games. The ROM here is 128 GB, and the memory is expandable via a hybrid tray. There is also support for Google Pay.

Advantages:

cute colors;
photographic opportunities;
a lot of permanent memory;
work of both SIM cards in 4G networks;
relatively compact;
stable operation of the NFC module.

Flaws:

not gaming performance;
The battery is only 3340 mAh.

Samsung Galaxy A71 6/128GB

Among smartphones under 25,000 rubles, the Galaxy A71 from Samsung stands out with its excellent set of features. Firstly, there is a 6.7-inch diagonal AMOLED matrix installed here. Below it is a fairly good fingerprint scanner. In terms of hardware, the smartphone is almost identical to the Poco X3, so it is perfect for any needs.

If for some reason you don’t have enough 128 GB of permanent memory, then you can install a microSD of up to 512 gigabytes in the device without sacrificing a second SIM card.

The smartphone battery has a good capacity of 4500 mAh. It charges quickly and holds a charge for a long time even with active use. The main camera is also not inferior to competitors, and the front camera with a resolution of 32 MP is even better than in other models. With all these advantages, the phone, by the way, is not too weighty (only 179 g).

Advantages:

fine iron;
excellent autonomy;
good AMOLED screen;
fast power supply included;
quite a good camera;
excellent combination of price and characteristics;
convenient OneUI shell.

Flaws:

the scanner is not always accurate;
quality of night photography.

realme 6S 6/128GB

Next in the ranking of the best smartphones with 6 GB of RAM is a new product from realme. Perhaps, in terms of price/quality ratio, the 6S model is the best choice on the list. There is a 6.5-inch screen with Full HD+ resolution and 90 Hz refresh rate. Why 120, like Poco X3? Firstly, not everyone needs this. Secondly, the difference will be noticeable for a small number of users, and the battery will be consumed faster.

In addition, the battery here, although good, is far from record-breaking - 4300 mAh. But with the performance of the smartphone everything is very good. Helio G90T is almost equal to Snapdragon 730G. If we talk about games, then with proper optimization by the developer, the chip from MediaTek copes even better with high graphics settings. The smartphone also boasts super-fast charging at 30 W, and a suitable power supply is included in the kit.

Advantages:

luxurious main camera;
display color rendition;
smoothness from sweep 90 Hz;
good set of cameras;
productive iron;
NFC for contactless payment;
separate slot for microSD;
fast battery charging.

Samsung Galaxy M31

If you want to choose a smartphone with 6 GB of RAM that will cope well with everyday tasks and run for a long time on a single charge, then the Galaxy M31 is ideal for you. It is equipped with a proprietary Exynos 9611 chip, which is only slightly better than the Kirin 710 processor installed in the Honor 20s. But the battery here has a capacity of as much as 6000 mAh, so one charge will last the phone for 3-4 days.

Of course, under heavy load the battery is consumed faster. But first of all, the Galaxy M31 smartphone was created for other tasks. And there are no problems with them. For example, you can easily pay via NFC in a store, take a cool selfie with the 32-megapixel front camera module, or capture cool pictures with the main camera. There is also a separate slot for flash drives, so there is enough space for software, video, and photos.

Advantages:

attractive price tag;
high-quality assembly;
excellent front camera;
contactless payment;
impressive autonomy;
system performance.

Flaws:

the case is extremely easily soiled;
weak video processor.

Honor 9X Premium 6/128GB

All the smartphones described above have a common advantage - a cutout in the screen. As you can judge from the reviews, smartphones are sometimes criticized for precisely this feature. But there are models on sale just for this case. For example, Honor 9X Premium, where the front camera comes out from the top end. This option is not best suited for frequent use, but the mechanism will definitely withstand rare selfies and periodic video calls.

The regular modification of the 9X model is also available on the market. It offers NFC, but it only has 4GB of RAM and dual rather than triple rear cameras.

In terms of performance, we have an exact copy of the Honor 20s. That is, you should not expect anything outstanding from this smartphone. The battery here is better (4000 mAh), so it is enough for a confident day of work even with a high load. The 9X Premium screen is made using IPS technology. Its diagonal is 6.59 inches and the resolution is Full HD+. The smartphone camera is capable of taking excellent photos during the day. But at night she shoots so-so.

Advantages:

volume of permanent memory;
good battery;
quality of daytime photography;
IPS display without cutouts;
film on the screen out of the box;
high-quality assembly.

Flaws:

no NFC module;
Not very fast charging.

Meizu 16 6/64GB

If you are looking for a smartphone under 25,000 rubles, you should definitely take a look at this model. The device with a fingerprint sensor directly on the screen is made in a minimalist design. The main camera is conveniently placed here - top center on the back surface, and the manufacturer has inserted a flash underneath it.

The main camera sticks out quite a bit, but it is not difficult to damage it by placing the smartphone on a table. Therefore, it is better to purchase a case for such a gadget right away.

A 6-inch screen, an 8-core processor and support for two SIM cards are not the only features of the phone. It has a chic dual camera of 12 MP and 20 MP with autofocus, optical stabilization and macro photography. The battery of the Meizu 16 smartphone is not ideal, but it’s not entirely bad either – 3100 mAh, plus it has fast charging. You can purchase the Meizu 16 smartphone model for an average of 18,500 rubles.

Pros:

clear screen colors;
powerful processor;
photo quality;
fast battery charging;
durable metal case;
great connection.

Minuses:

unfinished firmware;
The speaker is too loud.

How much RAM should your phone have?

To summarize, we can say that 4 GB of RAM is enough only for the most undemanding users. 6-8 GB of RAM will be the best choice for the average user. 10-12 GB is already more than enough for almost everyone. And 16 GB is more about saying that they exist. Although Android is designed in such a way that no matter how much you give it, it will still eat everything. It’s just that you will store in RAM everything that you don’t even need.

Of course, if your budget doesn’t allow for more and your phone only has 2 GB of RAM, you can use it too. Moreover, its performance is not enough to score such a volume. On the other hand, even in the budget segment there are models with 4, 6 and even 8 GB of RAM. Its type and speed are also important, but this is a topic for another discussion.

Why do you need RAM?

While the smartphone is operating, RAM stores data about the operating system and running applications that the processor processes. Unlike internal storage, RAM is energy efficient and is only used when the smartphone is turned on.

Here's how much RAM each process takes up:

To operate the OS, you need from 1 to 2.5 gigabytes, which is also affected by the proprietary shell from the manufacturer.
Demanding games take up to 1.5 gigabytes.
A browser with 3-4 open tabs will take about 900 megabytes.
Messengers, social networking clients and video hosting sites take 200-300 megabytes.

The best smartphones further optimize RAM consumption: the shell takes up less memory and runs faster. If the RAM is filled to the maximum, the system will automatically close applications or place them in the zRAM partition - the program is considered open, but data about its operation is placed on a flash drive, from where it loads much more slowly.

The top models are equipped with fast and energy-efficient memory of the LPPRD5 type, which is combined with the flagship chipsets Snapdragon 865 and Exynos 990. In second place is the “legacy type” LPPDR4X.
