Since the first device with 6GB RAM hit the market, there has been a debate about how practical and useful is such a large amount on a mobile phone. Or is it a gimmick? Well, the vast majority of users don’t know how much RAM their device features. Also, many don’t care either, until their device starts to lag and closes apps in the background.
Just think of, let’s say, 40 cars running side by side in a narrow traffic lane, how crowded and slow it would be. Now, imagine that 6GB RAM is just like a very wide traffic lane on which 40 cars could run side by side. Elephone Z1 using 6GB DDR4 RAM and 64GB of internal storage, can not only meet your needs for a large internal storage, but also provide your content at a high speed. With Elephone Z1 you could run 40 apps at the same time without any lag. So, just forget apps like task killers and lagging for good.
Try running 40 apps on your current phone simultaneously, and see what would happen.
