In 2025, second-hand iPhones are one of the hottest-selling smartphones in India. With Apple’s latest models like the iPhone 17 crossing the ₹1,50,000 mark, many smart buyers are turning to refurbished and certified pre-owned options. They get the same Apple experience without burning a hole in their pockets.

But here’s the catch: while there are trustworthy sellers offering warranty-backed refurbished iPhones, there are also shady marketplaces, unverified dealers, and risky deals floating around. If you’re not careful, you could end up with a locked device, a fake iPhone, or one that dies within months.

This second-hand iPhone buying guide will help you avoid the traps. Below are the 7 biggest red flags every buyer should watch out for and how platforms like Grest ensure safe, worry-free purchases.

Why Buying a Second-Hand iPhone is Popular in 2025

Apple products have always been aspirational in India. From college students to working professionals, owning an iPhone is often seen as a lifestyle upgrade. However, the price of a brand-new iPhone has made many potential buyers look at smarter alternatives.

Here’s why second-hand iPhones are trending:

• Cost Savings: Up to 40–50% cheaper than new models.
  

• Warranty Availability: Many certified sellers now provide 6–12 months warranty.
  

• Sustainability: Buying refurbished helps reduce e-waste and supports a circular economy.
  

• Feature Richness: Even a 2–3 year-old iPhone still beats many brand-new Android devices in performance.

Clearly, the demand is there. But with demand comes risk. Let’s dive into the 7 red flags.

1. No Warranty or Return Policy

If a seller isn’t offering a warranty, walk away immediately.

• Why it’s risky: Without warranty, if your iPhone develops issues like battery drain, faulty charging, or screen flickering, you’ll end up spending thousands on repairs.
  

• What to look for: A minimum 6-month warranty and an easy return policy.
  

At Grest, every iPhone comes with a warranty and hassle-free returns so you never buy blindly.

2. Missing Original Bill or IMEI Check

A genuine iPhone should always have verifiable documents.

• Why it’s risky: Without a bill, you can’t verify ownership. Some stolen or blacklisted devices circulate in the second-hand market.
  

• What to do: Always check the IMEI number (dial *#06#) and cross-verify on Apple’s official website.

Grest ensures every iPhone is IMEI-verified, unlocked, and 100% authentic.

3. Poor Battery Health (Below 80%)

The battery is the first thing to degrade in a used iPhone.

• Why it’s risky: Anything below 80% health means frequent charging, faster heating, and performance throttling.
  

• How to check: Go to Settings > Battery > Battery Health before purchase.

All Grest devices pass a multi-point quality check and include battery health reports for full transparency.

4. Physical Damage (Screen, Body, Camera)

Cracked screens, water damage, or scratched cameras are huge red flags.

• Why it’s risky: Repairs cost a bomb. An original iPhone screen replacement can go up to ₹20,000.
  

• How to inspect: Carefully check for dents, scratches, and hidden cracks near charging ports or buttons.

Grest-certified iPhones undergo professional refurbishment, ensuring they are in like-new condition before shipping.

5. Locked or iCloud-Linked Devices

This is one of the most common scams.

• Why it’s risky: If an iPhone is iCloud-locked, you can’t even use it. It will ask for the original owner’s Apple ID and password.
  

• What to do: During setup, ensure the device doesn’t ask for someone else’s credentials.

Grest guarantees factory-unlocked devices with no iCloud or SIM lock issues.

6. Unrealistic Pricing (Too Cheap to Be True)

If you see an iPhone 13 Pro Max for ₹15,000 run.

• Why it’s risky: Ultra-low prices usually mean counterfeit devices, stolen phones, or non-functional units.
  

• Smart approach: Compare prices across trusted platforms and choose realistic deals.

Grest offers transparent pricing, affordable but never suspiciously cheap.

7. No After-Sales Support

Buying is just the beginning. What if your phone has issues later?

• Why it’s risky: Many local sellers disappear once you’ve paid.
  

• What to look for: A platform that offers customer support, repairs, and replacement options.

Grest stands out with dedicated after-sales support so you’re never left stranded.
