How much RAM does your Android phone really need in 2022?
The most well liked telephones function a large gamut of RAM sizes. At one finish you may have (*12*)ultra-premium units up to 12GB or 16GB of RAM. On the different finish, funds telephones, a few of that have variants with simply 4GB of RAM. In the meantime, the center floor is filled with a variety of units with 6GB and ceaselessly 8GB of RAM.
Usually, more cost effective telephones have a tendency to have smaller quantities of RAM, whilst the top rate, high-end flagships providing extra. The query is, how a lot RAM do you wish to have when purchasing a brand new telephone? What’s the perfect quantity of RAM for an Android telephone in 2022? How a lot do you wish to have so as to add a bit future-proofing? Let’s to find out.
RAM vs switch house: Reminiscence control defined

Each laptop, together with your telephone, makes use of Random Get entry to Reminiscence (RAM). Your these days working systems, their information, and the OS, are all saved in RAM whilst the pc is operating. Ten or so years in the past, Android units had 512MB or 1GB of reminiscence. On the other hand, the common quantity of RAM in units grew temporarily. In 2022, many top rate units had 3GB of RAM and all over 2022 and 2022 4GB changed into the de facto same old. 4GB is now regarded as the naked minimal for a brand new tool.
Regardless of how a lot RAM your tool has, it’s a finite useful resource that needs to be controlled. While you get started a brand new app on Android it must occupy a portion of the reminiscence. Easy apps and video games will use a couple of hundred megabytes. Extra subtle video games would possibly use as much as a gigabyte of RAM, and probably the most not easy video games can use as much as 1.5GB of RAM.
With 4GB of RAM, there’s enough space for a number of medium video games or apps, in conjunction with the OS, to are living fortunately in combination. On the other hand, one day, there will probably be not more loose RAM.
Regardless of how a lot RAM your tool has, it is a finite useful resource that may run out. That is the place switch house is available in.
To care for this eventuality, trendy computer systems use a method referred to as swapping. The oldest and least used pages of reminiscence are written out to the switch garage, and the reminiscence they occupied in RAM turns into loose. If that swapped-out reminiscence is wanted later, the stored reminiscence pages are learn again from garage and copied again into RAM (swapped-in). This a great deal will increase the volume of to be had reminiscence to retailer apps and knowledge however the trade-off is that it’s a lot slower in comparison to RAM.

Desktops, laptops, and servers use exterior garage (laborious drives, SSDs) as switch house. Android makes use of a moderately other method. As an alternative of writing out the pages to garage, Android compresses the information and writes it again into RAM. That is referred to as zRAM, following the Unix/Linux custom of the use of “z” to indicate compression. If we think a 50% compression ratio, 128KB of RAM can scale back to 64KB, liberating up 64KB. The (*14*)Linux kernel sees zRAM precisely as it might see conventional switch house. The compressed reminiscence isn’t without delay readable, so whether it is wanted it should be uncompressed and copied again, identical to conventional swapping-in.
On the other hand, switch house (particularly zRAM) may be a restricted useful resource. If Android runs out of switch house then it must change into extra competitive and get started culling apps already in reminiscence. That implies an app you sought after to go back to could also be compelled to near, as Android should make room for the brand new app you need to begin.
If Android runs out of switch house then it must get extra competitive and get started culling apps already in reminiscence.
What all this implies is that the extra RAM you may have, the extra apps you’ll be able to stay in reminiscence concurrently with out Android killing off older apps. Much less RAM implies that Android wishes to take away apps from reminiscence extra often. With that during thoughts, what’s the optimal quantity of RAM?
Trying out to search out the perfect quantity of RAM

To resolve the optimal quantity of RAM I examined three telephones: the (*8*)Samsung Galaxy S21 Extremely with 12GB of RAM, the (*15*)OnePlus 9 Professional with 8GB of RAM, and the Pixel 3XL with 4GB of RAM. The Samsung and Google units run Android 12, whilst the OnePlus runs Android 11. On each and every telephone, I famous the volume of loose RAM and the volume of switch house used. I then introduced a recreation, famous the volume of RAM the sport used, after which seemed on the adjustments to the loose RAM and the switch house. I repeated those steps till Android was once compelled to kill off an app already in reminiscence.

Here’s a checklist of the video games I used, in conjunction with the common quantity of RAM they occupy:
Subway Surfers — 750MB
1945 Airforce — 850MB
Sweet Overwhelm — 350MB
Brawl Stars — 500MB
Minecraft — 800MB
Asphalt 9 — 800MB
Shadowgun Legends — 900MB
Elder Scrolls Blades — 950MB
Genshin Affect — 1.4GB
Chrome — 2.2GB
Galaxy S21 Extremely and Pixel 3XL checks
Those two units take a seat on the extremes of the spectrum. The Galaxy S21 Extremely has 12GB of RAM, while the Pixel 3XL has simply 4GB. Beneath is a graph depicting how the units fared in my take a look at. Alongside the ground is the checklist of video games within the order that I introduced them. The blue line presentations how a lot loose RAM is to be had and the fairway line presentations how a lot switch house is used.
As you’ll be able to see, the S21 Extremely provides a virtually textbook instance of reminiscence control. As the volume of loose RAM decreases, the volume of switch house used will increase. With 12GB of RAM, the S21 Extremely was once ready to carry all of the video games in reminiscence beginning with Subway Surfers, then 1945 Air Power, proper on via Minecraft, Elder Scrolls Blades, and after all Genshim Affect. No apps have been killed off. To push the S21 Extremely to the edge, I began up Chrome and once I had opened 12 tabs and Chrome had used 2.2GB of reminiscence, Android was once after all compelled to kill Minecraft. Slightly spectacular. A deeper research of what came about may also be discovered within the video.
The 12GB Galaxy S21 Extremely supplies textbook reminiscence control and will cling a number of energetic apps immediately.
Issues have been moderately other at the Pixel 3 XL. It was once ready to carry three video games in RAM concurrently: Subway Surfers, 1945 Airforce, and Sweet Overwhelm. Once I introduced Brawl Stars, Subway Surfers was once killed off and got rid of from reminiscence. As we anticipated, this smaller quantity of RAM approach switch house is needed with a ways fewer apps, and just a handful may also be held in reminiscence immediately.

OnePlus 9 Professional take a look at
The OnePlus 9 Professional used for trying out has 8GB of RAM and contains the corporate’s RAMBoost function present in lots of its units. RAMBoost tries to make reminiscence control smarter. It analyzes your utilization and tries to stay apps you utilize often in reminiscence and kill off the apps that you simply don’t use ceaselessly. It’s going to even attempt to preload positive apps if it determines that you’re going to use them quickly. To correctly take a look at the OnePlus 9 Professional, I examined it with RAMBoost on and RAMBoost off.
The very first thing to notice concerning the take a look at with RAMBoost on is the spike in loose RAM when Sweet Overwhelm is introduced. This happened as a result of Subway Surfers was once killed off, despite the fact that there was once nonetheless a variety of loose RAM and switch house to be had. I restarted Subway Surfers and endured. Brawl Stars began with out factor, as did Minecraft. When Asphalt 9 was once introduced, Android killed off Sweet Overwhelm and 1945 Air Power.
The OnePlus 9 Professional is moderately competitive in its reminiscence control, terminating apps whilst there are nonetheless loose assets.
With RAMBoost switched off, Android behaves in a different way. I used to be ready to begin all of the apps, from Subway Surfers to Minecraft, with out the rest being killed off alongside the best way. Once I introduced Asphalt 9, Subway Surfers was once killed off.
What’s atypical about each checks run at the OnePlus 9 Professional is that apps are killed off when there are nonetheless loose assets. The OnePlus 9 Professional has 4GB of switch house to be had however simplest round 1GB is used when apps get started being got rid of. It kind of feels that the OnePlus 9 Professional is moderately competitive in its reminiscence control, particularly in comparison to the opposite telephones I examined.
So, how a lot RAM do you wish to have in your Android telephone?

Obviously, 4GB isn’t truly sufficient for a median quantity of multi-tasking. Most effective the latest three or four video games will stay in reminiscence. Productiveness apps have a tendency to be smaller than video games, so that you will have to be capable of run five or six smaller apps in combination prior to a few of them reload whilst you transfer again to them. 6GB of RAM will lend a hand to relieve this factor.
12GB at the Galaxy S21 Extremely may be very powerful and smartly controlled. No less than 15 video games, together with some giant ones, can stay concurrently in RAM, together with Google Chrome energetic pages. I doubt that any person would have a reason why to bitch or to be disenchanted through this stage of multitasking capacity.
8GB-12GB RAM is perfect, whilst 16GB appears to be not anything extra than simply bragging rights.
Whilst the OnePlus 9 Professional is competitive in its RAM control, long-term use of RAMBoost will have to lend a hand Android make higher use of its 8GB. However my assumption is that 8GB on different units will probably be applied higher than at the OnePlus.
In accordance with the effects, our advice is to try for 6GB of RAM when purchasing the cheap dear smartphone. For upper-mid-range or high-end units, 8GB will supply a excellent multitasking enjoy plus some future-proofing. What changed into transparent in our trying out, despite the fact that, is that the 12GB RAM at the Galaxy S21 Extremely is obviously a candy spot and will have to supply a perfect general enjoy to even probably the most not easy energy customers. Right now, 16GB RAM appears to be not anything extra than simply bragging rights.
