The reason why iOS with 1GB RAM can beat Android with massive RAM

A user on Quora explained that the Android system uses the Java environment to run applications, so extra memory is needed for garbage collection. That is, when an Android application finishes running, Java needs extra memory to reclaim the memory occupied by the application. Generally speaking, this mechanism works well on systems with sufficient memory. Once a large number of different applications are running, problems arise. The following table shows that an Android application theoretically uses one portion of memory, but in fact it needs four to eight portions of surplus for Java to recycle in order for the system to run smoothly. This is the reason why many Android applications will lag when opened.

This makes us understand why Android phones need to be equipped with massive memory, because more memory consumes more power, so naturally manufacturers have to increase battery capacity to ensure battery life. However, iOS system is not designed with such a garbage collection mechanism, but only allocates as much as the application requires. Therefore, Android flagship models are advertised in front of people with their massive memory and large battery capacity, but secretly shed tears of sadness.
