Top 9 Factors to Consider When Buying a Used iPhone
by Faraz Khan
Buying a used iPhone can be a savvy financial decision, allowing you to enjoy the quality and prestige of an Apple product without the hefty price tag of a new model. However, the process comes with its own set of challenges and considerations. In this guide, we’ll walk you through the top 9 factors you need to consider to make an informed and secure purchase.
Verify Activation Lock and IMEI Status
Activation Lock is a security feature introduced by Apple to prevent anyone else from using an iPhone, iPad, or iPod touch if it’s ever lost or stolen. Activation Lock is enabled automatically when you turn on Find My iPhone. With Activation Lock, the Apple ID and password initially used to activate the device are required to erase the device or reactivate it under a new account.
How to Check Activation Lock Before Buying
- Ask the seller to demonstrate that they can disable the lock by going to Settings > [ID name] > iCloud > Find My iPhone and toggling it off.
- Alternatively, during the physical inspection, reset the device and try to set it up to ensure that you aren’t prompted for the previous owner’s Apple ID.
Checking IMEI/MEID for Stolen Status
Every iPhone has a unique identifier known as an International Mobile Equipment Identity (IMEI) number, which is used by carriers and services to mark the status of the device.
- Stolen or Lost: The IMEI number can tell you if the device was reported stolen or lost. Purchasing a stolen phone can lead to it being unusable and potential legal issues.
- Blacklisted: A blacklisted phone is barred from accessing any cellular network, which typically happens when the device is reported lost or stolen.
- Insurance Claims: Devices replaced through insurance claims may also have their IMEI blacklisted if the original reported lost or stolen device is not returned.
How to Check the IMEI/MEID
- Directly from the iPhone: Go to Settings > General > About, and scroll down to find the IMEI/MEID number.
- Physical Inspection: If the iPhone is accessible, the IMEI is often printed on the SIM tray or, in older models, on the back.
- Using a Service: Input the IMEI number on the CTIA’s Stolen Phone Checker website or other similar services to verify the status of the phone. It’s essential to use a reputable service to ensure the data is accurate and up-to-date.
Battery Health Check
Battery health reflects the current capacity of the iPhone’s battery relative to its original state when new. It’s a crucial indicator of how long the device can operate before needing a recharge, and it impacts the overall user experience. As batteries age, their capacity to hold charge diminishes, and thus, assessing battery health in a used iPhone is vital.
Checking Battery Health
- Navigate to Settings > Battery > Battery Health.
- Here, you’ll see the “Maximum Capacity” percentage, which reflects the battery’s capacity relative to when it was new.
- The “Peak Performance Capability” indicator will tell you if the battery’s condition has affected the phone’s performance.
Importance of Battery Health Above 80%
A battery health above 80% is generally considered good for used iPhones. Batteries with a maximum capacity below this threshold may require more frequent charging and could experience unexpected shutdowns or slower performance during high-power tasks.
What Battery Health Percentages Mean
- 90-100%: Excellent condition, showing minimal wear.
- 80-89%: Good condition; the battery retains most of its original capacity.
- 70-79%: Fair condition; consider potential replacement soon.
- Below 70%: Poor condition; replacement recommended to ensure optimal performance.
Camera, Buttons, and Ports Functionality
Testing Autofocus and Clarity
- Open the camera app and test both the front and rear cameras.
- Take several photos in different lighting conditions to assess autofocus and clarity.
- Check for any issues such as blurry images, focus problems, or abnormal artifacts.
- Zoom in and inspect the photos for any smudges or scratches on the camera lenses that may affect image quality.
- Pay attention to any abnormalities in color reproduction or exposure consistency.
Assessing Additional Camera Features
- Test features like portrait mode, night mode, and video recording to ensure they function as expected.
- Check the camera settings menu for any missing or disabled features, which could indicate software issues or limitations.
Button Responsiveness
- Press each physical button on the iPhone, including the power button, volume buttons, and mute switch.
- Pay attention to the tactile feedback; buttons should feel firm and clicky, indicating good condition.

Testing Connectivity and Functionality
- Connect the iPhone to a power source and verify that it charges properly without any issues.
- Play audio through headphones connected to the headphone jack and check for clear sound output from both channels.
- Wiggle the cables gently to test for intermittent connections or loose ports.
Carrier Lock Status
Understanding Carrier Locking
- Carrier locking restricts a phone’s use to a specific network provider, preventing it from being used with other carriers’ SIM cards.
- iPhones sold through carriers are often locked to that carrier unless explicitly stated otherwise.
Verifying Carrier Lock Status
- Go to Settings > General > About on the iPhone to check its carrier lock status.
- If “No SIM restrictions” appears next to Carrier Lock, the iPhone is unlocked and can be used with any carrier.
- If a carrier name is displayed, the iPhone is locked to that carrier, limiting its use to their network.
Carrier Unlocking Procedures
- Unlocking a carrier-locked iPhone allows it to be used with any compatible carrier’s SIM card.
- Unlocking procedures and costs vary depending on factors such as the carrier, device model, and contract status.
Available Unlocking Methods
- Carrier Unlock: Contact the original carrier to request a carrier unlock. Some carriers offer this service for free, while others may charge a fee or require specific eligibility criteria.
- Third-Party Unlocking Services: There are third-party services and websites that claim to unlock iPhones for a fee. Exercise caution and ensure the legitimacy of such services to avoid scams or potential security risks.
