iPhone buyback testing follows 4 stages after arrival: identity and lock checks, safety and battery checks, function tests and cosmetic grading, and the result is compared with the answers in the quote. Inspection is completed within 1–2 business days of arrival, and payment is sent 1–2 business days after testing by PayPal, Zelle or bank transfer. When the phone matches the quote, the quoted amount is paid. When it differs, a revised offer is sent, and declining it leads to a free return. How to Sell iPhone Online in Six Steps shows where testing fits in the full process.
- Stage 1: model, storage, IMEI, Activation Lock and carrier lock.
- Stage 2: battery swelling, Battery Health and parts history.
- Stage 3: display, touch, Face ID or Touch ID, cameras, audio, buttons, ports and cellular.
- Stage 4: screen, back and frame grading, from Like New to Damaged.
What is checked first when an iPhone arrives?
The first checks confirm the phone's identity and whether it can be sold at all. The table lists them in order.
| Order | Check | Why it comes first |
|---|---|---|
| 1 | Package and contents match the quote | Confirms the right phone arrived |
| 2 | Physical safety: swelling or heat | A damaged battery is isolated before powering on |
| 3 | Model, storage and color | Sets the base price |
| 4 | Activation Lock status | A locked phone cannot be tested further |
| 5 | IMEI check for lost, stolen and financing flags | Decides whether the phone can be bought |
| 6 | Carrier lock status | Sets the unlocked or locked offer |
A phone that arrives still linked to an Apple Account is held while the seller removes it at icloud.com/find. A phone with a lost or stolen report is not bought. Activation Lock vs Carrier Lock vs Blacklist: The Differences explains each lock.
Which functions are tested?
Function tests cover every system a buyer uses. The table lists the common checks.
| System | Test |
|---|---|
| Display | Solid-color screens for lines, dead pixels, burn-in and tint |
| Touch | Every area of the screen for response and ghost touch |
| Face ID or Touch ID | Enrollment and unlock |
| Cameras | Each rear lens, the front camera, focus, stabilization and flash |
| Audio | Earpiece, loudspeaker and each microphone |
| Buttons and switches | Side, volume, Ring/Silent or Action button, Camera Control |
| Charging | Wired charging, data connection and wireless charging |
| Cellular | IMEI, modem firmware and a test call with a test SIM or eSIM |
| Wireless | Wi-Fi, Bluetooth and, where available, NFC |
| Sensors | Proximity, ambient light, compass and motion |
| Vibration | Taptic Engine |
A phone that fails a test is graded with that fault. How Much Is a Broken iPhone Worth? Fault-by-Fault Guide explains how faults are priced.
How are cosmetics graded?
Cosmetics are graded by inspecting the screen, the back and the frame under bright light, often with the phone tilted to show fine scratches. The phone receives one of 5 grades.
| Grade | Typical description |
|---|---|
| Like New | No visible marks at arm's length |
| Good | Light wear, minor scratches |
| Fair | Visible scratches or small dents |
| Poor | Heavy scratches, deep dents or worn finish |
| Damaged | A bent frame, heavy dents or broken parts |
A cracked screen and a cracked back are recorded separately from the grade, because each is its own question in the quote. iPhone Condition Grades When You Sell: Like New to Damaged explains each grade in detail.
How are battery and parts checked?
Battery and parts are checked in 3 ways: Battery Health shows maximum capacity and any Service message, iPhone 15 and later models show the cycle count, and Settings > General > About > Parts and Service History lists replaced parts as genuine or unknown on supported models. A Service battery or an unknown part adds a deduction. Selling an iPhone With an Unknown Part Message: Does It Lower the Price? explains the message.
How long does testing take?
Testing is completed within 1–2 business days of arrival. The hands-on tests for one phone take far less time; the window covers queueing, identity checks and any follow-up with the seller. The table shows the full timeline from shipment to payment.
| Step | Typical time |
|---|---|
| Transit | 2–4 days |
| Arrival scan | The day of delivery |
| Inspection | 1–2 business days after arrival |
| Payment sent | 1–2 business days after testing |
Business days exclude weekends and federal holidays.
What happens if something differs?
When the phone differs from the quote answers, a revised offer is sent by email with the reason. The seller has 2 choices:
- Accept: payment of the revised amount is sent 1–2 business days later.
- Decline: the phone is returned free.
Common reasons include a cracked back not declared, a carrier lock, a battery Service message and a function fault. Revised Offer Explained: What Happens If My iPhone Differs covers the process in detail.
Is my data safe during testing?
Data is safe during testing when the phone arrives erased, which is the expected state. Phones are erased again during processing. A phone that arrives with data still on it is erased as part of testing. The seller's own erase remains the first safeguard. Does a Factory Reset Delete Everything on an iPhone? explains how erasing works.
What happens after testing?
After testing and payment, phones in good working condition are typically refurbished and resold, phones with faults are repaired or used for parts, and phones with no reuse value are recycled. Reuse extends each phone's life and reduces electronic waste. What Happens to Your iPhone After You Sell It explains each path.
How can I make sure my phone passes as quoted?
Make sure the phone passes as quoted with 6 steps before shipping:
- Confirm the exact model and storage in Settings > General > About.
- Check the Carrier Lock line and the Battery Health screen.
- Inspect the screen, back and frame in bright light, without the case.
- Test the cameras, speakers, microphones, buttons and Face ID or Touch ID.
- Answer each quote question to match what you found.
- Turn off Find My, sign out and erase the phone.
How to Prepare Your iPhone to Sell: 9-Step Checklist covers the preparation steps.
What if my phone arrives damaged in shipping?
A phone that arrives with new damage, such as a crack that was not there when shipped, is graded on its arrival condition. Packing the phone with padding on all sides and photographing it before shipping reduces this risk. The prepaid label is tracked from drop-off to delivery. How to Pack and Ship an iPhone Safely When You Sell It covers packing.
Are phones tested by hand or by software?
Buyback testing combines diagnostic software, which reads identifiers, lock status, battery data and parts history, with hand tests by technicians for cosmetics, cameras, audio and touch. Software reads data reliably, while hand inspection finds cosmetic marks and faults that software cannot judge.
What does testing not check?
Testing does not check personal data, because phones arrive erased, and it does not run water immersion tests, because those risk damage. Liquid exposure is judged from visible corrosion and liquid contact indicators. Testing also does not judge accessories, which are not part of the offer.
How do I follow the testing status?
Follow the testing status on the tracking page with the quote number and email address. The status moves from label created to in transit, received, tested and paid. An email confirms each change, including any revised offer.
Which quote answers are checked against testing?
Each quote answer is checked against a specific test. The table maps them.
| Quote answer | Test that confirms it |
|---|---|
| Model and storage | Diagnostic read of the device identifiers |
| Carrier status | Carrier Lock status and IMEI records |
| Device balance | IMEI financing records |
| Powers on and works | Full function test sequence |
| Cracked screen | Visual inspection of the display glass |
| Cracked back | Visual inspection of the back glass and camera lenses |
| Cosmetic grade | Inspection of the screen, back and frame under bright light |
Answering each question to match the phone keeps the paid amount equal to the quote.
Why do buybacks test Activation Lock before anything else?
Buybacks test Activation Lock early because a locked phone cannot be set up, so most function tests cannot run. It also confirms the seller has released the phone. When the lock is on, the seller is contacted to remove it at icloud.com/find, which works while the phone is at the buyback.
How are faulty phones tested?
Faulty phones are tested the same way as working phones, and each fault is recorded. A phone that does not power on is checked for charging response and recovery mode before it is graded as non-working. A phone with a cracked screen still runs the touch and display tests where the glass allows. Every result feeds the final offer.
How are sealed phones tested?
Sealed, unopened phones are inspected for an intact factory seal and matching box labels, and the IMEI on the box is checked against lost, stolen and financing records. The seal is opened only when needed to confirm the device. How to Sell a New, Unopened iPhone for Cash covers sealed phones.
Are several phones in one box tested separately?
Several phones in one box are tested separately, each against its own quote. One phone's result does not change another phone's offer. Label each phone or note its IMEI on a slip in the box to keep them matched to their quotes. Sell iPhones in Bulk covers larger groups.
How does testing handle water damage?
Testing handles water damage by checking for corrosion in the ports and SIM tray, inspecting liquid contact indicators where visible and running the full function sequence. Liquid exposure often causes several small faults, such as muffled audio and failed charging, which testing records individually. Declare any liquid exposure in the quote form. Can You Sell a Water-Damaged iPhone? explains pricing.
Does testing differ for older models?
Testing follows the same stages for older models, such as the iPhone 11 or iPhone SE 2nd generation, with model-specific checks: Touch ID instead of Face ID on SE models and a SIM tray inspection on models with a physical SIM. Parts and Service History appears on iPhone XS and later with recent iOS versions, with more detail on newer models.
Can I ask why my phone received a revised grade?
A seller can ask for the reason behind any revised grade. The revised offer email states the reason, and support answers questions Monday to Friday, 9am to 5pm ET, at sales@sellusediphone.com. Include the quote number in the message.
Is the case or box checked during testing?
Cases, boxes and cables are not graded, because the offer covers the phone alone. Ship the phone without its case.
Frequently asked questions about iPhone buyback testing
What do buybacks check when they receive an iPhone?
Buybacks check identity and locks first: model, storage, Activation Lock, IMEI flags and carrier lock. They then check the battery and parts history, run function tests on the display, touch, Face ID, cameras, audio, buttons, charging and cellular, and grade the screen, back and frame from Like New to Damaged.
How long does iPhone buyback testing take?
Testing is completed within 1–2 business days of arrival, and payment is sent 1–2 business days after testing by PayPal, Zelle or bank transfer. Business days exclude weekends and federal holidays. Including transit, most sales complete in about 1 week from the day the phone is shipped. A free quote with these details shows the exact offer, which stays valid for 14 days.
What happens if my iPhone fails a test?
When an iPhone fails a test that was not declared in the quote, a revised offer is sent by email with the reason. Accepting it leads to payment 1–2 business days later. Declining it leads to a free return of the phone. A phone that matches the quote answers is paid the quoted amount.
Do buybacks erase my iPhone during testing?
Buybacks erase phones again during processing as a second safeguard, but the seller should erase the phone before shipping. Signing out of the Apple Account before the erase also removes Activation Lock, which is required for testing to continue at a working grade. Testing within 1–2 business days of arrival confirms the result before any payment is sent.
How are iPhone cosmetics graded?
Cosmetics are graded under bright light into 5 grades: Like New, Good, Fair, Poor and Damaged, based on scratches, dents and wear on the screen, back and frame. A cracked screen and a cracked back are recorded separately, because each is its own question in the quote form. Payment follows 1–2 business days after testing, by PayPal, Zelle or bank transfer.
