Phone specs that actually matter (and the ones that do not)

Shops lead with the numbers that are cheapest to make big. Here is what each spec actually changes when you use the phone, and where the marketing is noise.

Chipset: the one that decides how long the phone stays usable

The processor matters more than anything else on the sheet, and it is the spec least often advertised. A phone with a weak chipset and 8GB of RAM will feel slower in two years than one with a strong chipset and 4GB. Look up the exact chipset name — not "Octa-core", which tells you nothing — and compare it against other phones in the price range.

RAM: more helps, until it does not

RAM decides how many apps stay open in the background. Below 4GB you will feel apps reloading constantly. Between 4GB and 8GB the difference is real but modest. Above 8GB on a mid-range phone it is mostly a number on a poster. Ignore "virtual RAM" or "extended RAM" claims — that is storage being used as slow RAM, and it is not the same thing.

Storage: the one people regret

64GB fills up fast once WhatsApp media and photos accumulate. 128GB is the sensible floor for a phone you will keep. Check whether there is a microSD slot — many newer phones have dropped it, and the ones that kept it are worth more over time for exactly that reason.

Battery: capacity is only half the story

mAh is the headline, but a big battery behind an inefficient chipset and a high-refresh screen can last less than a smaller one. Charging speed matters more than most people expect day to day. So does whether the phone supports charging while the screen is off without throttling.

Screen: refresh rate is real, resolution mostly is not

The jump from 60Hz to 90Hz or 120Hz is immediately visible in scrolling. The jump from Full HD to higher resolution on a 6-inch screen is not, and it costs battery. AMOLED versus LCD is a genuine difference in outdoor visibility, which matters in Nairobi sun.

Camera: megapixels are the most misleading number on the box

A 108MP sensor on a cheap phone usually produces worse photos than a good 12MP one, because sensor size, lens quality and image processing matter far more than pixel count. Look at sample photos taken at night, not the megapixel figure.

The spec nobody prints: how long it gets updates

Security patches decide how safe the phone is in three years. Check the manufacturer’s stated update policy for that model before buying. On a phone that holds your M-Pesa and your bank app, this matters more than the camera.

Common questions

Is a more expensive phone safer from theft?

The opposite. A newer flagship is worth more to resell, which makes it a more attractive target. Protection is about what the phone captures, not what it cost.

Should I buy new or second-hand in Kenya?

Second-hand is reasonable value if you do the checks — see the guide on buying a second-hand phone safely, and run the IMEI through the checker in front of the seller.
