So you found a decent deal on a used iPhone 15, and you are this close to hitting “pay now.” Hold up for a sec. A used iPhone can be a genuinely smart buy as you get flagship features for a fraction of the price, but only if the phone actually checks out. Skip the inspection, and you might end up with a locked device, a battery on its last legs, or worse, a phone that’s not even legally the seller’s to sell.
This guide walks through exactly what to check before you buy a used iPhone 15 in India, so you walk away with a solid phone instead of a problem.
Why People Are Buying Used iPhone 15 Right Now
The iPhone 15 launched at a premium price, and even a year or two later, it’s still not cheap brand new. A refurbished iPhone 15 or a well-maintained used unit gets you the same Dynamic Island, USB-C port, and 48MP camera- just without the full retail hit to your wallet. Totally makes sense as a move, as long as you are not buying blind.
10 Things to Check Before You Buy
1. IMEI Number and Blacklist Status
This is non-negotiable. Every iPhone has a unique IMEI number, and an iPhone 15 IMEI check tells you if the phone is blacklisted, reported stolen, or has an unpaid finance history attached to it.
It’s quick to do:
- Dial *#06# on the phone, and the IMEI pops up right away.
- Check it against the box if the seller still has one, and against Settings > General > About.
- Run it through Apple’s coverage checker or a trusted IMEI lookup site to make sure it’s clean and verify the coverage status.
If the seller starts avoiding the question or the box doesn’t match the phone in front of you, just walk away. It’s not worth the risk.
2. Activation Lock and Find My iPhone Status
Here’s the thing – a phone can turn on just fine and still not really be usable if it’s tied to someone else’s Apple ID through Find My iPhone. Ask the seller to remove it right there in front of you (Settings > General > Transfer or Reset iPhone > Erase All Content and Settings). If they can’t, or they get weird about it, that’s your sign to stop and not buy the phone. Otherwise you could end up with a phone that’s basically locked forever.
3. Battery Health Percentage
Battery degradation is real, and it’s one of the biggest hidden costs of buying used. Go to Settings > Battery > Battery Health & Charging and check the Maximum Capacity number.
- 85% or above is generally solid for a used phone.
- Below 80% means you’ll likely notice faster drain and might need a replacement soon-Â factor that into your negotiation.
4. Screen Condition and Touch Response
Hold the phone up under bright light and really look at the screen- scratches, weird discoloration, dead pixels, all of it shows up better this way. Then just use it for a minute. Scroll around, type something out, open a few apps. If the touch feels off or laggy anywhere, especially near the edges, that’s worth flagging before you pay.
5. Physical Body and Water Resistance Seals
Look closely for dents, a bent frame, or any gap between the screen and the body; that gap, in particular, is a sign the phone’s been opened before. And here’s something people miss: a phone that’s taken a hard enough drop can lose its water resistance even if it looks totally fine from the outside. Also check at the edges of the back camera lens rings and cover, if the fit is not snug, it it has gaps, it is an indication that back glass has been replaced.

6. Genuine Parts Check
Some used phones on the market have had screens, batteries, or cameras swapped out with non-original parts, sometimes without the seller even knowing. You can check this by going to Settings > General > About and looking for a Parts and Service History section (available on iPhones running iOS 15.2 and later) it will flag if any major component isn’t genuine Apple hardware. This is also a good way to verify past repairs of major components.
7. Camera and Face ID Functionality
Open the camera app and test all lenses- main, ultra-wide, and the front camera. Then set up Face ID temporarily to make sure it actually recognises your face reliably, since a faulty Face ID module is an expensive fix.
8. Network and SIM Compatibility
Make sure the phone’s actually unlocked and plays nice with Indian networks like Jio, Airtel, or Vi. Some iPhone 15 units floating around India were originally locked to a carrier overseas, and unlocking one after the fact isn’t always simple; sometimes it’s not even possible.
9. Original Bill and Box
Ask if they still have the original invoice, box, and accessories. It’s not just about getting the full package – a genuine bill is proof the phone wasn’t stolen, and it’ll matter later if you need warranty help or decide to resell.
10. Panic / Error Reports:
It is generally a good idea to check if the device has hardware error logs or Panic error logs from past. They will not show up if the device has been reset. However, if you do come across any panic error logs in the iPhone, it is usually an indication of an underlying hardware failure.
To check for Panic Logs, goto Settings > Privacy and Security > Analytics and Improvement > Analytics Data.
11. A Proper Diagnostic Check
Before you finalize anything, run Apple’s own hardware diagnostics on the phone. It’s built into iOS and takes just a couple of minutes, no app or technician needed.
How to enter Diagnostics mode:
- Turn off the iPhone completely.
- Press and hold both the Volume Up and Volume Down buttons together.
- While still holding them, plug the phone into a power adapter.
- Release the buttons once the Apple logo shows up.
- When the message about diagnostics appears, tap Start Session and follow the on-screen steps.
This runs a check across the phone’s core hardware- display, battery, sensors, and more and flags anything that isn’t working as it should. If it comes back clean, that’s a strong sign the phone’s in good condition. If it flags something, you will know exactly what you are negotiating on, or whether to walk away entirely.
