Does Android KitKat version utilize less Random Access Memory than earlier versions do? Is there a good chart to show RAM utilization of multiple Android versions
Although some people say that KitKat 4.4 can run comfortably with only 512 MB RAM, it is safe to say that with more RAM it can run better.
According to Google's Compatibility Definition Documents, the Minimum Application Shared Storage
for each system is as follows:
Jelly Bean 4.3 - 1GB
Ice Cream Sandwich - 1GB
Gingerbread - 1GB
Froyo - 2GB
Eclair - 2GB
Donut - ???
Hope that helps!
Thanks. Please tell , the shared storage is for Random access memory or internal storage?
This article, although from October, explains why Kit Kat uses less memory than previous versions. http://www.webpronews.com/google-details-android-4-4-confirms-smaller-memory-footprint-2013-10 Less background processes are being used along with less memory some processes use when running allows Kit Kat to run on devices with 512MB RAM.
Thanks. I have viewed the link in your answer. Please tell , does it imply that background processess ( like say Trucaller app , Media ) won't be allowed to run after device gets booted?
The reduction in apps running in the background are mostly the system apps and devices, not third party apps. To reduce third party apps from running in the background at startup, you would need to root your device and use an autorun manager app. Otherwise, uninstalling or changing the app settings would need to be performed.
*background processes and services, not devices.
