Buy with a clearer picture.

Start with the phone you already use

Write down what needs to improve: battery reliability, storage, camera reach, screen size or a specific workflow. If your current phone otherwise works well, compare the cost of service with replacement.

Separate needs from preferences. A different colour is a preference; enough storage for work is a requirement. A shortlist with two or three requirements is easier to compare than a long list of impressive specifications.

Choose the model before the listing

Understand condition and refurbishment

“New”, “open box”, “refurbished” and “used” describe different selling situations, but a label alone does not establish battery health or guarantee flawless operation. Read what the seller explicitly includes.

Ask whether photographs show the actual item or a representative device. Check the screen, frame, lenses, charging port and buttons. If a description mentions a failed camera, Face ID fault, management restriction or activation problem, treat that as a functional issue rather than normal wear.

For refurbished phones, compare the stated testing process, battery commitment, warranty and return terms. A cosmetic grade such as “excellent” is not a standardised battery percentage across every seller.

Make battery condition part of the budget

Ask for current battery-health information and any relevant service messages. Where available, request the parts and service history. If the seller cannot supply this information, keep that uncertainty in your price comparison.

Do not turn a single percentage into a guarantee of hours between charges. Signal strength, brightness, navigation, games, temperature and battery age all affect everyday use.

Compare the delivered price plus a possible battery-service cost with a listing that has a clearer battery commitment. Also check who would perform the service and whether it changes the warranty or return arrangement.

Choose storage with a simple check

Open your current phone’s storage settings. Note what is used by apps, photos, messages and downloaded media, then allow room for growth. Your own usage is a better starting point than a generic claim that everyone needs the same capacity.

If you stream most media and keep few large games, paying for the highest tier may add little value. If you keep offline video, shoot frequently or travel without reliable internet, compare the next capacity up.

Cloud subscriptions can help manage photos and backups, but they do not increase physical capacity for installed apps. Include any subscription cost in your budget.

Unlocked and international: check both

A carrier-unlocked phone can still be the wrong regional version for you. Ask for the exact model number and confirm network compatibility and SIM requirements with your carrier. Do not infer a physical SIM slot from a photograph of another variant.

For an imported listing, verify shipping destination, applicable tax and import charges, warranty arrangements and the return address. A low item price can become expensive once delivery or a return is included.

Currency display and marketplace location do not, by themselves, mean that a phone is a domestic model or that all charges are included. Use the final checkout details and seller terms.

Your pre-purchase checklist

1. Confirm the actual phone. Match the model, storage, colour and selected variation to the price you will pay.
2. Ask about battery and repairs. Request current battery information and the parts/service history where available. A cosmetic grade does not answer these questions.
3. Check activation and carrier status. Require an activation-ready device and confirm compatibility with your carrier, including physical SIM or eSIM requirements.
4. Read the exceptions. Missing cameras, failed Face ID, management restrictions and functional faults can be buried in the description.
5. Compare the delivered cost. Include shipping, applicable taxes, import charges and the cost of returning a faulty device.

Apple’s preowned iPhone checklist explains checks including Activation Lock, battery condition and parts history. Inspect the device promptly after delivery while your return window is open.

Look beyond the advertised price

Imagine two listings for the same unlocked iPhone with the same storage and condition. Which costs less to buy?

Illustrative example only — these are not live offers. All amounts use the same currency, whether USD, EUR, GBP or another currency. Assume no additional tax or import charges for this calculation.

Offer B saves you 15 in the currency being compared. That is why you should compare the delivered total, not just the large price shown on a listing.

Comparing international offers? Check the currency code: USD, CAD and AUD are different currencies even though each may use a dollar symbol. Convert totals to the same currency before comparing, and include any applicable conversion fees, taxes and import charges. Confirm the final payment amount at checkout.

Then check battery information, any stated faults and return terms. If those differ, the phones are no longer equivalent offers: decide whether the better-documented condition or more suitable terms justify paying extra.

How we make comparisons

Specification tables use Apple’s published technical information. Our practical advice explains potential buying implications; it is not a first-hand test report or a measured battery, camera or performance benchmark. Listing prices and seller claims are separate from manufacturer specifications.
