Most people selling their iPhone focus on price and delivery. Few think about what should happen before the sale. Skipping preparation steps has real consequences: data exposure, Activation Lock disputes, lower prices, and last-minute transaction failures. Here are the eight things every seller should do - including two that most people discover too late.
1. Note Your iPhone's Serial Number
Before you do anything else, note your iPhone's serial number. Go to Settings → General → About → Serial Number. Screenshot it and save it. This is your proof of ownership if you need to report fraud, track a lost device, or verify warranty status. Once you've sold the phone, you can't access the serial number without the buyer's cooperation.
2. Back Up Everything (Including WhatsApp)
Standard iCloud or iTunes backup covers most things. But WhatsApp chats require a separate backup - the standard iCloud backup does not include WhatsApp by default.
To back up WhatsApp: Open WhatsApp → Settings → Chats → Chat Backup → Back Up Now. Verify the backup timestamp says "Today" before proceeding.
3. Check Battery Health and Fix Expectations Early (#3 That Most People Skip)
Go to Settings → Battery → Battery Health & Charging. Note the Maximum Capacity percentage. If it's below 80%, buyers will deduct ₹2,000–₹5,000 - and rightly so, since a replacement costs that much. Knowing this number early helps you set the right price expectation rather than being surprised during inspection.
If your battery health is 79% or below, consider: Is it worth paying ₹3,000–₹4,000 to Apple for a battery replacement to get ₹4,000–₹6,000 more in resale? Often yes - for iPhone 13 and newer.
4. Download All Your Paid Apps and Content
App Store purchases are tied to your Apple ID, not the device. Any apps, games, or in-app purchases you've bought will be available on your next phone. But locally stored content - offline maps, downloaded Netflix episodes, podcast files - will disappear when you wipe. Review what you need to re-download or transfer.
5. Transfer or Export App Data That Isn't Cloud-Synced
Some apps store data locally and don't sync to iCloud. Health data is the big one - but it's included in encrypted iTunes/Mac backup. Others to check:
- Authenticator apps (Google Authenticator, Authy): Export your 2FA codes before wiping. Losing these can lock you out of your accounts
- Banking and investment apps: Note your login credentials; re-KYC is common after device change
- Notes: Sync to iCloud. Confirm all notes are showing on iCloud.com
6. Remove Your Apple ID From All Services (#6 Most People Forget)
Signing out of iCloud is necessary but not sufficient. Your Apple ID is linked to several services that may persist independently:
- iMessage: Deregister your phone number at selfsolve.apple.com/deregister-imessage so the buyer's SIM doesn't receive your iMessages
- FaceTime: Go to Settings → FaceTime → toggle off before signing out
- Apple Pay: Remove all cards in Settings → Wallet & Apple Pay before wiping
- Paired accessories: Forget all paired Bluetooth devices in Settings → Bluetooth
7. Clean the Device Physically
This sounds trivial but it genuinely affects first impression - and first impression affects price negotiation. Buyers and inspection partners form a condition assessment in the first 10 seconds. A device with a smudge-free screen, clean speaker grilles, and clear camera lens looks like it was cared for. Use a microfiber cloth, a soft toothbrush for speaker grilles, and a lens cloth for cameras.
8. Gather the Original Accessories
Original box, Apple charging cable, earphones (if included), and documentation add tangible value in India's used market - ₹500–₹2,000 depending on model. More importantly, they create buyer confidence. A phone in its original box looks like it belonged to a careful owner.
Can't find the box? Not a dealbreaker, but note it honestly when booking - it ensures your quote is accurate and there are no deductions at pickup.
