The reason why Android phones need more RAM than iPhones

Mine Pixel 6 Professional It has extra random entry reminiscence (RAM) than a desktop pc. This pc shouldn’t be knowledgeable system – my job is usually typing – however the level: high-end Android telephones have loads of reminiscence. It is common to see 12GB on present Android telephones just like the Pixel 6 Professional and better bezels Galaxy S22 Extremely; Some telephones have 16GB of RAM or extra. The iPhone 13 Professional, then again, has 6GB of RAM, whereas the non-Professional variations solely get 4GB — however they nonetheless carry out higher or higher than Android telephones with twice that. How might that occur?

What’s RAM?

RAM means RAM. There are a number of sorts of RAM, however the one utilized in smartphones, SDRAM, is unstable In contrast to your telephone’s non-volatile flash reminiscence, the place info is saved long-term, RAM can solely maintain info whereas your system is working. It is principally your telephone’s working reminiscence – it comprises the knowledge your system is actively utilizing at any time.


The extra RAM your telephone has, the extra issues it will possibly maintain in its working reminiscence. As you open further apps (or further content material inside one app), your telephone allocates out there RAM to every new course of. Finally, there is no such thing as a RAM out there, and your system has to resolve which processes to terminate to maintain issues working easily. All else being equal, a telephone with 8GB of RAM will be capable of maintain extra energetic processes than one with 4GB of RAM, so switching between actions might be sooner on the Telephone with extra RAM.

Why does Android want extra RAM than iOS?

There isn’t a particular trigger, however there are numerous contributing components as a substitute. First, Android and iOS apps are constructed in a different way. There are solely a handful of recent iPhones and iPads yearly, and so they all run on comparable units. Since iOS apps solely run on just a few homogeneous segments, they are often tailor-made to these segments utilizing so-called Sweetened Programming languages ​​(notably Swift and Goal-C). Code written for iOS apps is instantly compiled into directions that Apple CPUs can perceive with none form of translation.

However, Android powers an infinite variety of completely different units, with chipsets created by Qualcomm, Samsung, MediaTek and others that have to run the identical apps. Since it could be not possible to make sure compatibility manually with all completely different {hardware} configurations, Android apps are written in programming languages ​​(Kotlin and Java) that may be translated into some form of frequent language which is then translated again into native code for a given chipset. This frequent language is known as byte code.

Bytecode shouldn’t be restricted to any explicit system, so the system should convert the code to native code earlier than it may be executed. In comparison with executing native code instantly, the way in which iOS does, this course of consumes further sources, which implies that an app that seems and works identically throughout Android and iOS will sometimes require extra out there RAM to run on a Pixel 6 than it does on a tool. Pixel 6 iPhone 13.

Every working system additionally manages RAM in a different way. Android makes use of a reminiscence administration methodology known as Rubbish assortment. This course of periodically makes an attempt to uproot objects in reminiscence which might be not in use and may unlock RAM. However iOS makes use of Automated reference rely (ARC), which mechanically assigns an integer worth to things in reminiscence based mostly on what number of different objects they check with, eradicating objects whose worth reaches zero.

Since rubbish assortment solely periodically clears unused objects, this could result in transient accumulations of ineffective info that results in a rise within the quantity of RAM. ARC, against this, doesn’t have this downside – single, pointless objects are faraway from reminiscence as quickly as they’re acknowledged.

Android is much less restricted to apps working within the background than iOS too, so apps that you do not actively use can reside within the RAM on Android telephones extra simply than iPhones. The flexibleness of the Android working system is without doubt one of the biggest strengths of the platform, however this flexibility could require much less environment friendly use of RAM.

Finally, Android and iOS have completely different wants for RAM as a result of the 2 working methods work in a different way – Android is a way more versatile working system than iOS, each when it comes to what {hardware} it will possibly run and the way builders can use it. This flexibility comes at the price of larger RAM necessities for iPhone-like efficiency.

However contemplating the iPhone 13 Professional Max priced at $1100 and $450 Samsung Galaxy A53 Every has six gigabytes of RAM, which is a fairly easy reminiscence that is not too costly. Whereas Android may have extra RAM, the additional reminiscence is not essentially a foul factor if producers can supply flagship telephones at a worth much like and even decrease than comparable iPhones.
