Short answer: In Delhi NCR you have three routes — the physical grey market around Gaffar Market and Nehru Place, online marketplaces, and brands that renew devices themselves. The first is cheapest and carries the most risk. Whichever you choose, the checks are the same: verify the IMEI, confirm battery health as a stated number, and insist on a GST invoice.

The three routes, honestly compared
| Grey market | Online marketplace | Renewal brand | |
|---|---|---|---|
| Price | Lowest | Middle | Middle |
| Battery | Original, often unstated | Varies by seller | Replaced — 100% health |
| Warranty | Usually none, or verbal | Varies, often via third party | 18 months on iPhone |
| GST invoice | Frequently not offered | Usually | Always |
| Recourse | None once you leave | Platform dispute process | Direct with the brand |
| You can inspect first | Yes | No | On delivery |
If you buy in the physical markets
Gaffar Market in Karol Bagh and Nehru Place are the two best-known hubs, and plenty of people buy there without incident. The saving is real. So is the risk, and it is concentrated in things you cannot see.
Go with these rules.
Check the IMEI before money changes hands. Dial *#06#, then SMS KYM <15-digit IMEI> to 14422. Blacklisted, duplicate or model-mismatch results end the conversation. Full method: IMEI check India.
Open Settings yourself. Check Battery Health, and check the device is not activation locked to someone else's Apple ID. If the seller will not hand you the phone unlocked, walk away.
Treat “above 80%” as a warning. It is the widest claim a seller can make while being technically truthful, and it covers a battery at 81 per cent.
Insist on a GST invoice with the IMEI on it. A cash discount for no bill is not a discount — it removes every protection you have. See why the GST invoice matters.
Do not pay before testing. Cameras, both SIM slots, speakers, every button, wireless charging. The 9-step checklist covers the full sequence and takes under ten minutes.
What you are actually paying for with a brand
The price gap between a market phone and a renewed one is not margin. It is a replaced battery, a documented quality process and a warranty that someone has to honour.
A market phone at ₹13,000 with an original battery at 82 per cent will likely need a battery replacement within the year. A renewed device at ₹15,499 at 100% battery health with an 18-month warranty will not. Once you add the replacement cost, the cheaper phone frequently is not.
Work it out yourself in cost per year of ownership.

Checks to run on delivery
Buying online removes the ability to inspect before paying, so do it on arrival instead — before you transfer your data across.
Confirm battery health reads 100% in Settings. Verify the IMEI on screen matches the invoice, and check it against the government database. Confirm the device is not activation locked. Test both SIM slots, all cameras and every button. Keep the invoice somewhere you can find it in eighteen months.
Then set it up. If anything is wrong, it is far easier to resolve before your data is on the device.
