Why Do iPhones Need Less RAM than Android Devices? | QR #49

I feel like iOS vs Android has been a debate for so long. Both are great operating systems with their pros and cons but what we are gonna talk about in this article is a little bit different. Have you ever wondered why iPhones have less RAM than Android devices and yet they outperform them in so many different areas? Well, not everyone knows this but it is closely related to their design principles about background processes. Let me explain further…

Why do iPhones need less RAM than Android devices?

iPhones need less RAM to operate because Apple has less applications running in their background. They achieved that by simplifying the communication process of their devices. They only need one port to communicate with Apple’s server, instead of the multiple different ports for each application that Android has. 

Important Notes:

  1. Both operating systems have a “push notification” system which allows them to get an update from the application and then deliver it to you in the notifications area of your smartphone. For instance, somebody sends you a message on Facebook, you then get a notification on your phone and you open the application to connect to the Facebook server and start receiving data.
  2. Apple’s “push notification” system is independent and works like this: They have their own server which communicates with the application and then they send the notification from their server to you. The iOS does not allow the apps to take RAM size according to their preference and when you shut down any application, iOS automatically deallocates any memory that’s in use. As a result, fewer APPS run background processes and therefore, less RAM is required.
  3. On the other hand, Android’s “push notification” system works like a computer system. In other words, each APP has its own background process which allows it to communicate with the user and directly send notifications from their server. Consequently, more background processes means more RAM is needed.
  4. iOS is written in “Swift” while Android and its applications use “Java” which is known for recycling the used memory back into the system.
  5. Apple has full control over iOS. They are aware of the needs that each application has in terms of memory and as a result, they make iPhones run efficiently. Google on the other hand doesn’t have that kind of control over Android devices.


To conclude, if you compare a high-end iPhone and an Android, you’ll find very few differences since their phones are compensated with extra GB of RAM. However, some iPhones reach faster speeds due to the lack of unnecessary bloatware. That’s all for this topic. If you have any further questions, let me know in the comments down below. Peace out!
