Buying a refurbished phone is one of the smartest ways to save money and still enjoy premium performance. But not all refurbished phones are equal. Some are almost new, while others may show signs of wear or hidden issues.
That’s why it’s essential to know how to check a refurbished phone’s condition before you buy. Whether you’re shopping online or in-store, this guide will help you inspect, verify, and feel confident that your next purchase is genuine and worth the price.
1. Understand Refurbished Phone Grades
Most refurbished phones are categorized by grades usually Grade A, B, and C.
Here’s what they mean in simple terms:
-
Grade A: Looks almost new. Minimal or no visible marks. Excellent battery health.
-
Grade B: May show light scratches or small signs of use but works perfectly.
-
Grade C: Noticeable wear, but still fully functional and tested.
Always confirm the grade before purchase. Reputable sellers like Zexton clearly list this information so you know exactly what to expect.
2. Start with a Physical Inspection
When your refurbished phone arrives, check the physical condition first. Look closely at:
-
Screen: Should be bright, responsive, and free from cracks or dead pixels.
-
Frame and body: Minor marks are fine, but deep dents may indicate drops.
-
Buttons and ports: Check that the power button, volume keys, charging port, and SIM tray work smoothly.
-
Speakers and microphone: Play music and make a call to test for clear sound.
A quick hands-on inspection helps you identify any obvious defects right away.
3. Check the Screen and Display Quality
The display is one of the most important parts of your phone. To test it properly:
-
Open a white background to check for discoloration or bright spots.
-
Swipe through the screen to ensure there are no dead zones.
-
Adjust brightness settings to confirm responsiveness.
If the touch or color feels inconsistent, it may have been repaired with a low-quality replacement screen.
4. Test the Battery Health
Battery health is key when assessing a refurbished smartphone condition. For iPhones, go to Settings → Battery → Battery Health to see the percentage. Anything above 85% is good.
For Android phones, you can use diagnostic apps or enter specific codes (like *#*#4636#*#*) to view battery capacity.
A high-quality refurbisher replaces batteries that fall below acceptable levels, so don’t hesitate to ask for this info before buying.
5. Verify the IMEI Number
Every genuine phone has a unique IMEI number. It helps verify if the device is authentic and not stolen. To check:
-
Dial *#06# to display the IMEI number.
-
Visit imei.info or the manufacturer’s website to confirm model and authenticity.
If the IMEI doesn’t match the brand’s records, or shows a blacklisted status, avoid the purchase.
6. Test the Software and Hardware Functions
Your refurbished phone should perform as smoothly as a new one. Take a few minutes to test:
-
Camera: Take photos and videos in different light conditions.
-
Wi-Fi and Bluetooth: Connect to ensure proper functioning.
-
GPS: Test map accuracy.
-
Sensors: Rotate the screen or use a compass app to test motion sensors.
-
Face ID or fingerprint: Set it up to check response speed.
These tests help confirm that the refurbisher ran a full diagnostic before resale.
7. Check Network Compatibility
Before buying, confirm that your refurbished phone is network-unlocked.
If it’s an unlocked model, it should work with all major UK networks such as EE, O2, Vodafone, and Three. Insert your SIM card to ensure you can make calls, send messages, and use mobile data immediately.
8. Assess the Warranty and Return Policy
Always check for a refurbished phone warranty before buying. A reliable seller will provide at least 6 to 12 months of coverage for defects or malfunctions. Equally important is the return policy you should be able to return or exchange the phone if it doesn’t match the described condition. Brands like Zexton are known for clear warranties and customer-friendly return options, giving you confidence and protection.
9. Verify Seller Authenticity
Before completing a purchase, ensure the seller is legitimate and trustworthy. Look for:
-
Verified website or business details.
-
Clear contact information and reviews.
-
Transparent product grading and warranty terms.
-
Secure payment methods (PayPal, credit card).
Avoid sellers who can’t provide official documentation, receipts, or return support.
10. Run a Diagnostic App
If you want a deeper check, run a refurbished phone diagnostic test.
Apps like Phone Doctor Plus, TestM, or AccuBattery help assess hardware functions, display quality, battery capacity, and sensors. This gives you full peace of mind that everything inside your refurbished device works properly.
11. Compare Refurbished vs Used Phones
It’s important to know the difference:
-
Refurbished phones are tested, repaired if needed, and sold with a warranty.
-
Used phones are sold as-is, with no inspection or guarantee.
Always go for refurbished over used you’ll get better quality, warranty coverage, and safer buying conditions.
12. Tips for Buying Refurbished Phones Safely
Here are a few quick tips to keep in mind:
-
Always buy from verified UK refurbishers.
-
Check for battery health and IMEI authenticity.
-
Read reviews before choosing a seller.
-
Avoid prices that look too good to be true.
-
Save your purchase receipt for warranty use.
