Electronics
Phone marketing is a megapixel race, but the things that make a phone feel old are the chip, the software support window and the battery. Camera sensor size beats megapixel count every time.
Quick answer
Latest-gen chip + 6+ GB for a smooth 3–4 year life.
storage, not ; 128 GB minimum.
AMOLED with 90+ and 1000+ outdoors.
Check software update promise and battery size.
In the shop
Read these off your phone at the counter. The answer tells you more than the price tag.
1.“Which exact chipset is inside, and what is the sensor behind the 108 MP number?”
A good answer: A chipset name you can look up. Megapixels without a good sensor and processor means slow, mushy photos.
2.“How many years of Android/OS and security updates are promised?”
A good answer: A stated number of years in writing. “Lifetime updates” is not a thing.
3.“Is the display brightness enough for outdoor use — what is the peak nits figure?”
A good answer: 800+ nits peak. Below 500 and you'll be shading the screen with your hand every afternoon.
A few questions about your situation, not about the product.
Add one short need not covered above.
Answer all 3 questions to see the spec sheet to shop with.
Most smartphone purchases are financed. Check the monthly outgo and the interest you actually pay before you decide which spec level you can afford.
Monthly EMI
₹4,119 (≈$49)
Total interest
₹2,073 (≈$25)
Total paid
₹37,073 (≈$440)
A no-cost EMI offer should make this equal the price.
Reducing-balance calculation. Processing fees, GST on interest and insurance are not included, so confirm the final schedule with your lender. USD values are approximate.
A case and screen protector are cheap insurance against the most common repairs.
Tempered glass absorbs impact that would otherwise crack the display.
Corner reinforcement matters more than looks for drop protection.
These are common add-ons for this category, not recommendations. Prices and availability vary; confirm fit and compatibility on the product page before buying.
For electronics the expensive failures are the display, the board and the battery. Extended cover is worth it only when it names those parts and offers a repair path in your city.
Ask these five questions
Usually not covered
Rule of thumb: worth considering on a high-value device you carry around, rarely worth it on a low-cost one where a plan costs more than ~15% of the price.
These are comparison links, not recommendations — we don't sell plans and we don't rank providers. Some outbound links on KnowBeforeBuy are affiliate links. Cover, exclusions and pricing change; read the plan document before you pay.
If you are upgrading, a buyback quote changes the real cost of the new purchase.

Buy it locally
Sometimes the local dealer beats online on price, installation or the exchange offer. Tell us where you are and we'll list nearby stores. We don't rank or take money from any shop; results come from Google Maps.
The area you enter, or coordinates rounded to about 1 km if you use your location, are sent to Google Maps through Lovable to find places. Lookups are temporarily cached for up to 30 minutes.
The main chip; smaller nm numbers usually mean cooler and more efficient.
Why it matters
It decides smoothness three years from now, not on day one — every phone feels fast in the shop.
What to check
Renamed last-gen chips in 'new' phones. Search the exact chip name, not the phone name.
Working memory, and how fast the built-in storage reads.
Why it matters
2.2/3.1/4.0 storage affects app launch and camera burst speed far more than extra 'virtual '.
What to check
'8+8 GB ' is 8 GB plus swap on storage. Ignore the second number.
AMOLED vs LCD, 60/90/120 , and peak outdoors.
Why it matters
High refresh makes cheap phones feel expensive; 800+ peak decides whether you can read it in sunlight.
What to check
PWM dimming on cheap AMOLEDs gives some people eye strain at night.
How much light the sensor collects, and whether it is stabilised.
Why it matters
A 50 MP sensor with beats a 108 MP one without it, especially indoors and at night.
What to check
2 MP 'macro' and 'depth' cameras exist to pad the spec sheet. They add nothing.
mAh capacity plus charging wattage.
Why it matters
5000 mAh with an efficient chip is a genuine two-day phone; fast charging matters more than capacity if you top up daily.
What to check
Fast charging shortens battery lifespan; check whether the charger is even in the box.
How many years of OS and security updates are promised.
Why it matters
This is the real expiry date of the phone — banking apps eventually refuse old versions.
What to check
'2 years of updates' on a phone launched 8 months ago means roughly 16 months left.
Water resistance, screen protection, and supported network bands.
Why it matters
IP68 survives accidents; missing 5G bands make an imported phone slower on your network.
What to check
IP54 means splash resistant only. Grey-market imports often lack local bands and warranty.
Typical range: budget workhorse to flagship; the biggest jump in feel happens in the mid tier.
