MrDong, 07 Feb 20218GB RAM is more than sufficient and it’s not like you’ll do... moreThe kernel-space: Your Android phone runs on top of the Linux kernel. The kernel is stored in a special type of compressed file that's extracted directly into RAM during the device power-on sequence. This reserved memory holds the kernel, drivers and kernel modules that control the hardware and room to cache data in and out of the kernel.A RAMdisk for virtual files: There are some folders and files in the system tree that aren't "real." They are pseudofiles written at boot and hold things like battery levels and CPU speed data. With Android, the whole /proc directory is one of these pseudofile systems. RAM is reserved so they have a place to live.Network radios: Data about your IMEI and radio settings are stored in NVRAM (Non-Volatile memory that's not erased when you power off your phone), but get transferred to RAM along with the software needed to support the modem when you first turn on your phone. Space is reserved to keep this all in memory.The GPU: The graphics adapter in your phone needs memory to operate. That's called VRAM, and our phones use integrated GPUs that have no stand-alone VRAM. System RAM is reserved for this.

While Android's way of keeping background services, receivers, and alarms run in the background is open, it gives developers the control to make apps like Tasker which you cannot possibly find on iOS. Freedom is liberty, I believe. And Android trusts that developers would be responsible while making use of the freedom. Sometimes it does wonders, sometime it just messes with the system. There are ways to kill such an app through OS and OS is the sole decision maker in that regard.

Moreover, Apple vertically integrates its devices which means it has a tight grip down to the level of materials used in a component. That means Apple can freely optimize their hardware for software and their software for hardware. Google can do that to some extent with Nexus devices (that's why they outperform current Android flagship and iPhones too).

MrDong, 07 Feb 2021Lol the S21+ does not even use a plastic back. I thought it... moremuch less RAM size?

First of all, it is because of the way the operating system of the iPhone is designed. iOS is written in " Swift". While, Android, whose majority of apps and the system itself are written in Java. Android selected java because java is a virtual machine that helps to combine the OS code, enabling the OS to run on many devices and processor types with different hardware configurations from different manufacturers

Secondly, iOS devices do not undergo garbage collection to recycle used memory back to the system while closing the application.

Thirdly, Apple has more control over iOS than Google has over Android. Apple is well aware of what type of hardware and devices should be used in each operating system so that the iPhone operates efficiently and smoothly.

Not only android devices are bloated but the android applications also function in the background taking a lot of RAM's space to function smoothly.

The memory of Android is managed by the operating system. On the other hand, the memory of the iPhone is regulated by the apps themselves. The iOS does not permit the apps from taking RAM size according to their preference and then freeing it when no longer in use. In fact, the iOS apps allocate and deallocate memory as per their requirement, automatically.

Ios is fake bogus Darwin Unix platform than android running Linux.
It's like android is you know how many or whose getting on the bus with no limits, ios is limited to certain people because the cache memory is very low so it freeze at the background rather than running.

Common sense, use your brain or learn the java program.

Apps are actually encouraged to use as much RAM as they need. Then, every once in a while, Android cleans up the data in RAM that's no longer being used ("garbage") and frees it, allowing other apps to use it. This method, while effective, is most optimal when there's a lot of RAM to play with, otherwise the system spends too much time always collecting garbage.

I thought it... moreGenerally, the more RAM your system has, the larger the digital countertop you have to work on and the faster your programs will run. ... However, adding RAM is a better solution because your processor can read data from RAM much faster than from a hard drive.

This is android where apps run in background once open unlike fake bogus is where apps stay in cache memory.

Joker, that's like saying more power and knowledge is not required. And why you complain for having 16 or 34gb ram? Why is it hurting you? Is it heavy fir you too carry?
The more ram the more apps you can run, without reloading a page, if you have less ram every time you open a Web page with 8gb ram it reloading, when I browse on my s21ultra 16gb ram it doesn't need too reload .

Only ddr4x or ddr5.

Jt, 07 Feb 2021Because of water resistanceand design newer deigns have wireless charging and other ribbons on top or near battery would cost them more and make phone thicker
as they getting rid of chargers done think would want spend money

AnonD-966113, 07 Feb 2021Ikr! Wtf do people use 8gb ram for!? 4gb is sufficient for... moreMany Android phones get bottlenecked when using apps or games with just 4GB of RAM. Samsung’s OneUI consumes roughly 2GB of RAM, so you don’t have much left. I think 6GB is the bare minimum, 8 is just right, 10 above are excessive.

4gb is sufficient for me.
6gb is more than enough!

Marvin, 06 Feb 2021Just a basic question, if you are using a plastic back, why... moreSorry but the back’s glass to start with. Unless you’re talking about the regular S21. Removable plastic back will cancel splash and water resistance.

Seul8tr, 06 Feb 2021Because a shttttyyyy 8gb Ram. Plastic cheap back instead of... moreLol the S21+ does not even use a plastic back. I thought it was plastic at first, but after testing in a store I found out it was frosted glass back like the iPhone 12 Pro. The build quality is premium enough.

8GB RAM on a phone like that is more than enough, it’s not like you’ll have to multitask a lot and if you do so the CPU will be stressed anyway. There are phones out there with high RAM but poor CPU, especially lower end models from Oppo and Vivo (ex. Oppo A9).

Seul8tr, 06 Feb 2021Because a shttttyyyy 8gb Ram. Plastic cheap back instead of... moreHuge difference between cheap feeling plastic and this premium looking matte plastic.

Hi Samsung please don't make fool people with your exynos . At least you Snapdragon in flagship models.

Epic fail with 8gb Ram.
This phone will not sell like the 12gb ram S205g
