Intro to Checking Used iPhone
Checking Used iPhone ~ Many people buy used iPhones as a backup or temporary device. We often receive inquiries from frustrated buyers who suddenly find their iPhone locked by the previous owner’s iCloud (Find My). Worse, some sellers disappear without helping. To avoid this headache, follow this complete guide before buying a used iPhone!
How to Check Used iPhone if it is Locked
1️⃣ Ask the seller to sign out of their Apple ID:
•Settings > [Name] > Sign Out.
•This ensures the device is no longer linked to their iCloud account.
2️⃣ Check for Activation Lock:
•Reset the iPhone to factory settings.
•Settings > General > Reset > Erase All Content and Settings.
•After the reset, set up the iPhone. If it asks for the previous owner’s Apple ID and password, the phone is LOCKED.
3️⃣ Avoid shady sellers:
•If the seller refuses to reset the phone or provide proof that it’s unlocked, walk away or best RUN!
•Always meet in a safe, public place and test the phone thoroughly before paying.
•REMEMBER: A locked iPhone is useless unless you have the previous owner’s Apple ID and password. Don’t fall for scams!
Check Used iPhone Hardware Function
1. AirDrop
Send a photo, video, or file to another iPhone to ensure AirDrop works properly.
2. Apple ID
Log in with your Apple ID and password. Try downloading an app like WhatsApp to confirm the device allows sign in.
3. Assistive Touch
Enable Assistive Touch and move the button around the screen to check for any unresponsive or dead spots.
4. Bluetooth & Hotspot
Pair with another phone or connect to a personal hotspot to verify Bluetooth connectivity.
5. Battery Health
Go to Settings → Battery → Battery Health & Usage. If the battery percentage drops suddenly or the “Battery Health” option is missing, the battery was likely replaced with a third party (non original) one.
6. Buttons
Press all buttons (power, volume, mute switch) to check for proper functionality.
7. Camera & Face ID
Test both front and rear cameras by taking photos and videos. Check for any spots or blurriness. Also, try adding a new Face ID to confirm it works.
8. Charging & Overheating
Plug in a charging cable and try wireless charging. Ensure the phone charges normally without overheating.
9. Display Screen & True Tone
Adjust the brightness manually. Cover the front light sensor to see if the screen dims automatically. Also, test True Tone in display settings.
10. Mic & Speaker
Make a call using both the regular mic and loudspeaker. Play a video to check for any distortion or crackling sound.
11. NFC
As Malaysians, we can test NFC by trying to reload a Touch n Go card using the back of the iPhone (for enhanced TNG cards).
12. SIM & eSIM
Insert a physical SIM card to check if the phone detects it. If using an eSIM, ensure the phone allows eSIM activation.
13. Torchlight
Turn on the torch and test brightness levels to ensure it functions correctly.
