It all depends on how you use your smartphone and whether or not you can live with a slight lag encountered every now and then. If you are someone who is into heavy multitasking, using multi-window feature to get more than one task completed at a time, you will be better off with a higher RAM handset. However, if you are an average user even 2 GB is more than enough for all your needs - even if you’re on Facebook, Whatsapp, Instagram throughout the day.

It depends on the number of processes running in the background, opened by the user and always-on features. Please bear in mind that certain apps and processes are always running in the background including radio networks, social media and telephony, among others. Therefore, not all of the RAM is available to the user straight out of the box. Moreover, as user installs more and more apps while using the handset, as it is intended to, the RAM keeps getting filled. Therefore, do not be surprised when you see only 2GB or less RAM available when you have a 4GB handset.

In any computing device, the performance is directly proportionate to the amount of memory there is to dump files and process. More RAM means, the running processes and apps have more space to operate smoothly. This results in smooth execution and operation of the handset. Therefore, if you are a heavy user, who is into gaming and multitasking quite a lot, you will benefit from higher RAM. However, even then 3GB of RAM is more than enough for anything.

Selecting the best handset from those available in the market completely depends on your usage pattern and preferences. Do not just buy any device that claim to have 4GB of RAM but also analyse whether the processor in it supports higher RAM and whether the user interface as well as bloat on it is already taking up too much RAM already. 4GB RAM phones may turn out to be overkill but why compromise when you need the best of the lot. You can opt for any flagship device of the top brand offering this much memory but look out for battery. Battery should be solid enough to support the heavy usage.
