Why does iPhone require less RAM than Android devices ? Exact Answer

Why does iPhone require less RAM than Android devices

Why does iPhone require less RAM than Android devices:- Normally we saw that iPhones use less amount of RAM than any Android smartphone if we talking about the flagship Category. Why? Did you ever think about it? If yes, then you are in a right place.

You will see that on Android, there are many smartphones available in the market which are even using 6 and 8 GB of RAM but lost with an iPhone which has merely 2GB of RAM. If we take an eg. of flagship smartphones, we saw that on one side there is Google pixel and Samsung S7 Edge, both have 4 GB of RAM, and on another side, there is iPhone 7, which has merely 2 GB of RAM, and it can compete with pixel and S7 edge successfully neck-to-neck.

Iphones are way more expensive than Android devices even with the same specifications. However, the iPhone works a lot smoother and faster than an Android device with the same amount of RAM.

Why does iPhone require less RAM than Android devices ? Exactly what are the main reasons behind this? So, Today is the time of discussing the factors which lead apple to use less RAM on their smartphones.

Why does iPhone require less RAM than Android devices ?

So friend, let’s analyze all the factors behind ” Why does iPhone require less RAM than Android devices ?” one by one. Starting from software, ending at Hardware.

1. App management

As you all know, iOS is only running on the devices which are manufactured by Apple itself. But, in Android, the case is completely different. Mostly all of the smartphone manufacturers either it is Samsung or OnePlus is running on Android. Google has their own smartphone series for Android named Nexus (now,  it’s pixel), but all other smartphones are running on Android.

App Development

So, in this case, for app developers, the creation of app through writing scripts is easy in the case of iPhones but difficult for Android devices. Why?

Because they know, if they are developing their app for iOS, devices, then the scripts they will right is only for iPhones compatibility, But if they are creating a script for Android, they know there are tons of Smartphones manufacturers, all have their own USP, features, hardware compatibility and more, this leads to creating an app which every Android device supports. Some devices run that app smoothly and some are lagging while handling that app as hell.

Another reason is background processing system of both the platforms. Yes, processing is also one of the factors behind our question ” Why does iPhone require less RAM than Android devices ?”  In Android, we can see lots of apps which are already running in the background, creating and running their own processes.

Android already provided a lot of freedom to app developers that cause memory leaks or resource hogging background processes, that’s why need to be careful what you install on your Android device. Good news is that Android had already made some attempts to control this, such as killing apps that use too much CPU, but still, these problems can be noticed by the user, and it will be resolved very soon.

But in iPhone, They already put a lot of limitations on the developers and what they can do causes them not to do much harm. They use a different algorithm which helps to track all the background running apps and check their respective processes continuously. And when any app become idle, immediately it kills the background process.

2. User Interface

Basically, you experienced that in Android, that the User Interface (UI) lags sometimes but this is not a case with iPhones. Why? Let’s discuss it Separately.


Because in Android, all apps, files, and UI are running in a similar thread, means there is not any kind of separation between them, all are running and using the same part of RAM every time. This means that other apps in Android can take over the processor resources and hurt basic UI interactions, translating into a noticeable lag. This lag appears, especially when any heavy app (like asphalt 8 or GTA San Andreas) is running in the background.

But this is not a case with iPhones. In iPhones, there is a separate thread running for UI, in simple words, iPhone separate all the UI processes by provided it a system reserved (or you can say dedicated) RAM, from which even if there is any heavy app is running in background, UI doesn’t lag because, for UI, RAM is free.

3. Background Processes Handling – Java VS ARC


As you all know, in our Android Operating system, there are some apps which are continuously running in the background,  which constantly creates cache data and hence, need garbage collection, as cache data is temporary, it becomes useless after a particular amount of time.

So in this case, the whole process uses the Java language. So, this background processing and cache data not only acquires the storage but also the RAM until the garbage collection is increasing. In simple words, More garbage increasing = more RAM. That’s why some android phones with less RAM lag sometimes even when no app is running.


In the case of iPhone, they use a different way to manage that processes, named as ARC (Automatic Reference Counting). What this process does is:- it handles all background processes in a way that it creates cache memory and automatically deletes it after that work is accomplished. This means that as long as there are “strong” references to an object, it will not be deallocated. Strong cross-references can accordingly create deadlocks and memory leaks.  In this way, the garbage collection is very less in iPhones, hence leads to provide tremendous RAM management.

4. Hardware and Software Calibration

In terms of hardware and Software Calibration, Apple takes an edge. Why? Let me answer you. This thing is to be noted that if there is any smartphone manufacturer who creates their own smartphone as well as the operating system for it had a perfect chance to make their smartphone unique and free from bugs.


Yes, this rule is applied to Apple as well as on Google.  Apple has their own unit of Smartphones hardware parts [display, processor series, RAM, etc.] which they assemble, and add their own operating platform [iOS] in it.That’s why We will only see smartphones running on iOS are manufactured by Apple itself only. So, they have a very less responsibility and provides better hardware-to-software Calibration in it, leads to fewer bugs and better experience.

But in case of Google, they created an android, but launched it as an open source platform, means, any smartphone manufacturer can use Android as an operating System. That’s why Google has to take care of each and every smartphone that is running on Android, hence, providing less hardware to software calibration. Really, it’s a very big responsibility on Google as compared to Apple, But I trust, one day google will beat apps in this segment Also. By the way, Google has also their own smartphones line-up named ” Nexus” which is now “Pixel”, and this series is very close to Apple iPhone series. Let’s hope for the best.
