Buying a second-hand iPhone or Android device in Chennai can save you up to 50% off retail prices. Follow this essential verification checklist before handing over cash.
1. Verify IMEI & Surcharge Records
Dial *#06# on the phone keypad to display the physical IMEI number. Match this IMEI against the original purchase invoice and box packaging.
2. Perform Display & Touch Screen Test
Open a blank white screen to check for screen burn-in or dead pixels. Test multi-touch responsiveness across all display corners.
3. Check Battery Health & Charging Port
For iPhones, navigate to Settings > Battery > Battery Health. For Android, check charging speeds and port tightness using a portable power bank during physical meeting.
