Apple’s iOS is twice as memory-efficient as Android

“An iPhone 6 with 1GB of RAM runs much faster than a similarly specced Android smartphone with 2GB of RAM,” John Brownlee reports for Cult of Mac. “And it all has to do with the fundamental difference in the way iOS and Android handle apps.”

“More RAM negatively affects battery life too, which is part of why Android phones need to have larger batteries to attain the same battery life as an iPhone 6 too,” Brownlee reports. “As for iOS? …It only needs the memory it’s using.”

“Android apps using Java, recycle released memory using garbage collection,” Glyn Williams explains via Quora. “Garbage collectors are really awesomely fast if you have a relative memory footprint of 4 or 8.”

“In other words, you need four or eight times more memory, than you are actually using to be super efficient. But when the memory becomes constrained, that performance goes way down,” Williams explains. “So 1GB for iOS results in more performance than 3GB for Android.”
