How to Understand RAM, Storage and Chipsets
Understand the basics so spec sheets stop feeling like a foreign language.
What Is RAM and How Much Do You Need?
RAM is where your phone keeps apps and processes that are currently open or recently used. More RAM helps with multitasking and reduces app reloads.
But beyond a point, software optimisation matters more than raw numbers.
- 4 GB – basic usage, light apps, some reloads
- 6 GB – comfortable for most normal users
- 8 GB – better for heavy multitasking and gaming
- 12 GB+ – niche and future-proof, but not mandatory for most people
Storage: ROM, UFS and Free Space
Storage (often called ROM) is where your apps, photos, videos and files live. Running near full storage slows down your phone and can cause issues.
Always leave some breathing room.
- Prefer at least 128 GB if you take lots of photos and videos
- 64 GB is okay for light users but fills quickly
- Look for UFS storage types (like UFS 2.2, 3.1) for faster app loading
- Keep 20–25% of storage free for best performance
Chipsets: CPU, GPU and Efficiency
The chipset is the brain of your phone. It controls performance, gaming, battery and camera processing.
You do not need to memorise every model number. Just know roughly which series are stronger.
Frequently Asked Questions
Is more RAM always better?
More RAM helps, but only up to a point. For most people, 6–8 GB is more than enough. It is better to balance RAM with chipset and storage instead of maxing out only one spec.
Why does my phone lag even with 8 GB RAM?
Lag can come from heavy apps, poor optimisation, very full storage or background processes. RAM is just one part of the performance story.
