How to Check a Refurbished Phone Before Buying: The Ultimate Buyer’s Checklist
Buying a refurbished phone is a smart way to save money while still getting premium features—but only if you know exactly what to check before you commit. With the rise of certified refurb phones and eco-conscious shopping, more people are turning to refurbished models. But without the right checks, you could end up with a dud.
In this guide, we’ll walk you through a complete refurbished phone checklist, covering physical inspections, feature testing, battery health check, warranty, and how to verify a phone’s authenticity. Whether you're browsing online or checking out cheap refurb phones for sale, here's everything you need to know before you buy refurbished phone models.
1. Physical Inspection: Check for Cosmetic & Structural Damage
The first step when you check before you buy refurbished phones is a full visual inspection. Look for any signs of wear and tear that might affect performance or resale value.
What to examine:
- Screen: Scratches, cracks, dead pixels, and discoloration
- Frame and buttons: Look for dents, loose buttons, or misaligned parts
- Ports: Check charging port, SIM tray, and headphone jack for corrosion or blockage
- Camera lenses: Ensure they’re clear and free of scratches
- Water damage indicators: Look for corrosion, moisture marks, or discolouration around ports and seams
Tip: Use a flashlight to inspect tight corners and port interiors for hidden damage.
2. Functionality Test: Make Sure Everything Works
Once the phone passes your physical inspection, test all features to confirm they work as expected.
Run through this test list:
- Touchscreen: Is it responsive across the entire screen?
- Display: Check refurbished phone’s brightness, dead pixels, or screen burn-in
- Speakers and Microphone: Make a call and play audio
- Cameras: Take photos and videos with front and rear lenses
- Sensors: Test fingerprint scanner, face ID, proximity sensor
- Buttons: Confirm all (power, volume, home) are responsive
- Reboot Test: Power it off and back on to check system performance
Pro Tip: Run a benchmarking app for advanced diagnostics.
3. Battery Health Check: Don’t Skip This One
Battery health is a dealbreaker. Refurbished phones may come with degraded batteries unless replaced.
What to check:
- Battery health % (for iPhones): Found in settings
- Battery life apps: Use apps like AccuBattery (Android) to get cycle count and capacity
- Replacement info: Ask if the battery was replaced and by whom
- Aim for 85%+ battery health or a newly replaced battery.
4. Warranty & Return Policy: Know Your Coverage
Even a refurbished phone should come with peace of mind.
Ask about:
- Warranty on refurbished phones: Is it from the seller or manufacturer?
- Duration: 3, 6, or 12 months?
- What’s covered: Battery, screen, internal components?
- Return policy: Can you return it if anything goes wrong?
Tip: Get warranty and return info in writing or via email before you buy.
5. IMEI, Unlock Status & Legitimacy: Avoid Stolen or Blocked Phones
Before you buy refurbished phones, always verify that the phone is legitimate.
How to check:
- IMEI number: Check in settings
- Blacklist check: Use IMEI checker tools to confirm it's not reported stolen
- Carrier lock: Make sure it's unlocked for use with any network
- Certification: Look for third-party certifications like Phonecheck
Never skip this step, it protects you from buying a stolen or unusable device.
6. Consider Future Software Support: Stay Secure and Up to Date
One of the most overlooked steps when buying a refurbished phone is checking its software longevity.
Why it matters:
- Security updates: Older phones may no longer receive essential patches, leaving you vulnerable.
- OS upgrades: Some devices won’t get the latest Android or iOS versions, limiting app compatibility and features.
- App performance: Outdated software can slow down performance and block access to new apps.
What to do:
- Check manufacturer support pages for how long your device is promised updates.
- Google Pixel phones typically get 3-5 years of updates.
- Samsung, Apple, and OnePlus also provide timelines on support for each model.
Tip: Avoid phones nearing end-of-life support unless you only need a short-term backup.
7. Understand Mobile Phone Grading: Know What You're Getting
Refurbished phones are usually sold with a condition grade, which tells you what to expect in terms of appearance and performance.
- Excellent Condition: These devices exhibit very little to no signs of prior use. They are typically in excellent cosmetic condition and function as if they were new.
- Good Condition: Devices in this category show some minor signs of wear, such as light scratches or scuffs. However, they are fully functional and operate as intended.
- Fair/Acceptable Condition: These devices have more noticeable signs of wear, including visible scratches, marks, or other cosmetic imperfections. Despite the appearance, they have been tested and are confirmed to be fully functional.
Why it matters:
- Helps you balance price vs appearance
- Lets you set realistic expectations before buying
- Ensures transparency from the seller
Tip: Always read the seller’s grading description and look for real product photos when possible.
What to Check When Buying a Refurbished Samsung Phone
When buying a refurbished Samsung phone, start with the same basic checks you would make on any refurbished device, but pay particular attention to the display, battery, software support and device information.
Use this simple refurbished Samsung phone checklist before making a decision:
- Check the display: Look for screen burn-in, dead pixels, discolouration and touchscreen issues, particularly on Samsung AMOLED displays.
- Assess the battery: Watch for unusually fast battery drain, overheating or charging problems. Samsung phone battery condition can vary depending on the device’s age and previous use.
- Test the cameras and sensors: Check the front and rear cameras, fingerprint sensor, speakers, microphones and physical buttons.
- Confirm the device details: Check the model number, serial number and IMEI through the phone’s settings and make sure they match the device you expect to receive.
- Check Samsung security updates: Older Galaxy models may have less software support remaining, so confirm the update status for the specific model before buying.
If you are comparing Refurbished Samsung Phones, these checks can help you understand the condition of the device and whether it is suitable for your needs before making a purchase.

Ever found yourself out and about, needing to work on your laptop, but there’s no reliable Wi-Fi? It’s a common scenario. Luckily, your smartphone holds the solution: tethering.
Tethering is a simple, effective way to use your phone's mobile data connection to get your PC online. Essentially, you're turning your phone into a portable Wi-Fi hotspot or a physical modem.
This comprehensive guide will walk you through the three main ways to tether phone to PC, ensuring you can get back to work (or play) swiftly and securely.
What is Tethering?
Tethering is the process of sharing your mobile phone's internet connection with another device, like a computer or tablet. It effectively turns your phone into a portable Wi-Fi router. You are "tethering" the two devices together to share the data.
You can tether phone to PC using a cable (USB), wirelessly (Wi-Fi hotspot), or via Bluetooth. Each method has its own advantages, which we will explore below.

Smartphones have come a long way in the past decade, from simple communication tools to powerful pocket-sized computers. But 2025 marks a turning point. The biggest upgrades are no longer about camera megapixels or faster processors. The real revolution is happening behind the scenes with AI in smartphones.
Artificial intelligence is reshaping how phones think, respond, predict, and interact with users. Whether it’s personalisation, photography, battery management, or voice assistance, AI is quietly powering the features we rely on every day. And with the next generation of AI chips, on-device assistants, and multimodal models, smartphones are evolving at a pace we’ve never seen before.
In this article, we break down how AI is transforming the smartphone industry, what it means for users, and what the future of mobile tech looks like in an AI-driven world.

These devices give you the ultimate power over your mobile experience. Instead of being stuck with one provider, you get the freedom to choose.

Apple’s September event has finally given us something concrete to work with in the iPhone 18 vs iPhone 17 conversation – but there is an important catch.
Apple announced the iPhone 18 Pro and iPhone 18 Pro Max on 9th September 2026, but there was no standard iPhone 18. Apple’s current UK iPhone range still positions the iPhone 17 as its standard model, with no confirmed standard iPhone 18 release date yet.
So rather than comparing the iPhone 17 against rumours, this guide looks at what Apple has actually confirmed for the iPhone 18 generation, particularly the iPhone 18 Pro, and whether those improvements give iPhone 17 owners a good reason to upgrade.
