Refurbished iPhone Buying Guide: 7 Things to Check Before You Buy

Short answer: a refurbished iPhone is worth buying when the seller checks out on seven things, the battery health (look for 80% or higher), the cosmetic grade (A, B or C), a strong warranty, network unlock status, a clean IMEI, the parts that were replaced, and a fair returns policy. Get those right and you save 30 to 50% versus new, with the same Australian Consumer Law protection. Below is exactly what to check, and what each one should look like, before you pay.

Is a refurbished iPhone actually worth it?

Yes, for most buyers. A refurbished iPhone is a pre-owned device that has been professionally tested, repaired where needed, data-wiped and certified to work like new. Because it is not boxed as brand new, you typically pay 30 to 50% less than retail for the same model. The trade-off is some cosmetic wear and, on older units, a battery that has aged. Both of those are knowable before you buy, which is the whole point of this guide.

The myth worth busting: "refurbished" does not mean "faulty" or "risky". A reputable Australian seller tests every device and backs it with a warranty. The risk only appears when a listing hides the details below. So treat these seven checks as your buying checklist.

1. Battery health: aim for 80% or higher

Battery is the part of an iPhone that ages first, usually after two to three years of daily charging. On an iPhone you can see its condition under Settings > Battery > Battery Health & Charging, shown as "Maximum Capacity". A brand new battery reads 100%. Apple considers a battery worth replacing once it drops below 80%, because that is when you start noticing shorter runtime (see Apple's battery health guidance).

So the rule is simple: a good refurbished seller guarantees at least 80% battery health, and replaces the battery with a new one if a unit tests below that. Before you buy, look for a stated minimum. If a listing says nothing about battery health, treat that as a red flag and ask. Every refurbished iPhone at OZ Tech Deals is tested against this 80% minimum.

2. The cosmetic grade: A, B and C explained

Grades describe how the phone looks, not how it performs. A Grade A and a Grade C iPhone of the same model have the identical processor, camera and speed. The difference is scratches and marks on the body and screen. The catch is that grading is not standardised across Australia, so one shop's "Grade A" can look like another's "Grade B". Always read the seller's own definition. Here is the common scale, and roughly what each is for.

Grade	How it looks	Performance	Best for
Grade A	Excellent. Minor marks not visible at arm's length, if any.	Full, identical to new	Buyers who want it to look near-new
Grade B	Good. Light to moderate scratches and small dings you can see up close.	Full, identical to new	The value sweet spot for most people
Grade C	Fair. More visible wear and possible deeper scratches.	Full, identical to new	Lowest price, or buyers who use a case anyway

Our honest tip: if you use a case and a screen protector (and you should), Grade B is usually the smartest buy. You pocket the saving, the wear lives under your case, and the phone performs exactly the same. Go Grade A only if you like a bare, pristine handset.

3. Warranty, and the Consumer Law rights you keep either way

Look for at least a 12 month warranty as a baseline, starting from the day the phone arrives. The best Australian refurbishers go further. Every device from OZ Tech Deals comes with a 24 month warranty, plus a 12 month warranty on the battery. A warranty that long tells you the seller is confident the device will keep working.

Here is the part most buyers do not realise: in Australia you also get consumer guarantees that cannot be waived, even on a refurbished phone. Under the Australian Consumer Law, goods must be of acceptable quality, and you are entitled to a repair, replacement or refund if they are not. These guarantees have no fixed expiry, they last as long as is reasonable for the price and type of product, which can extend beyond the written warranty (see the ACCC's consumer guarantees). So a refurbished iPhone bought from an Australian business carries the same baseline legal protection as a new one. That is a big reason buying local beats a cheap overseas listing.

4. Network unlock status: make sure it is unlocked

An unlocked iPhone works on any Australian carrier, Telstra, Optus, Vodafone and the smaller networks that run on them. A locked phone only works on the carrier it came from, which is a headache if you ever switch plans. Reputable refurbished iPhones are sold network unlocked, but it is worth confirming in the listing or with the seller. If it does not say "unlocked", ask before you buy.

5. A clean IMEI: not blocked, not iCloud locked

Every phone has a unique IMEI number. Two things you want confirmed. First, the IMEI is not blacklisted, a blocked IMEI (reported lost, stolen or unpaid) can be barred from Australian networks, leaving you with a phone that cannot make calls. Second, the device is fully removed from the previous owner's Apple account, with Find My iPhone and Activation Lock turned off. A properly refurbished iPhone is always factory reset and de-linked, so it sets up clean as yours. Buying from an established seller is the simplest way to never have to worry about this.

6. What parts were replaced, and whether they are quality

Refurbishing can involve swapping a worn battery, screen or back glass. That is a good thing when it is done with quality parts, it is how the phone gets certified to work like new. What you want is transparency: a seller who tests every device and uses quality components, and stands behind the result with a long warranty (24 months at OZ Tech Deals). If a price looks too good to be true, it sometimes means the cheapest possible parts. The warranty and the seller's reputation are your protection here, which brings us to the last check.

7. Returns policy and seller reputation

The final check ties the others together. Buy from an Australian business with a clear returns or change-of-mind window, real customer reviews and contactable support. A local seller means faster shipping, easier warranty claims and your full Consumer Law rights. Before you commit, skim the reviews, confirm the return window, and make sure there is a real way to reach a human. If all seven boxes are ticked, you can buy with confidence.

Frequently asked questions

Is it safe to buy a refurbished iPhone?

Yes, when you buy from a reputable Australian seller. The device is tested, data-wiped, certified to work like new and backed by a warranty, and you keep your Australian Consumer Law guarantees. The seven checks in this guide (battery, grade, warranty, unlock, IMEI, parts and returns) are how you confirm a listing is safe before you pay.

What does Grade A, B or C mean on a refurbished iPhone?

Grades describe cosmetic condition only, not performance. Grade A looks near-new with minimal marks, Grade B has light to moderate visible wear, and Grade C shows more obvious scratches. All three perform identically because the internals are the same. Grading is not standardised in Australia, so always read the seller's own definition.

What battery health should a refurbished iPhone have?

Look for a guaranteed minimum of 80% maximum capacity. Below 80%, Apple considers a battery worth replacing. A good refurbisher tests every unit and fits a new battery if it falls under that mark, so your phone holds a solid charge from day one.

How much do you save buying a refurbished iPhone?

Usually 30 to 50% less than the new retail price for the same model, depending on age, storage and grade. For example, you can pick up a refurbished iPhone 11 from $329 or an iPhone 13 from $499 at OZ Tech Deals, well below their original launch prices.

Do refurbished iPhones come with a warranty in Australia?

The better sellers include at least a 12 month warranty from the date you receive the phone. OZ Tech Deals goes further, with a 24 month warranty on every device plus 12 months on the battery. On top of that, the Australian Consumer Law gives you guarantees that cannot be excluded, so you are entitled to a repair, replacement or refund if the device is not of acceptable quality, even beyond the written warranty period.
