It does not work like this...then what is reason behind Making 8 gb , 10 gb phones?? Its true whatever heavy apps you use it will be difficult to consume even 1 gb ram..but more ram is free more your smartphone will run smooth...but in fact truely saying i believe there is no reason for buying 4gb ,6gb ram smartphones even 2gb,3gb ram is enough for heavy use too for normal user...what matter most is processor...but again i didn't like mi phone they ll slow down after 6-7 months of use there ui is full of ads redmi note 3 and 4 was launched 3 years back i guess ..do you see many peoples using that phones????...there battery ll be dead , phones ll be slow and stuck at loading screen...there is many reasons i hate redmi...real me is far better than mi and colors os is well optimized for smooth use and long battery life
