The market for pre-owned iPhones is growing rapidly, and not every seller offers the same quality. How do you distinguish a reputable seller from a dubious one? What questions should you ask? This practical guide will provide you with a complete checklist to protect you from a bad purchase and help you find a quality pre-owned iPhone at a good price on koupitiphone.cz.
Checklist: 8 Things You Must Find Out Before Buying
1. Battery Health
Battery is the most important parameter to ask about first. Apple iPhones display battery capacity as a percentage in Settings → Battery → Battery Health & Charging. This number indicates how much of the original battery capacity remains.
- 85% and above: Excellent condition, recommended for purchase
- 80–84%: Good condition, battery moderately worn
- Below 80%: Apple recommends replacement, battery life may be noticeably shorter
A reputable seller will always inform you of the battery condition beforehand or include it in the product description. On koupitiphone.cz, battery condition is transparently listed for each device.
2. IMEI Check — Verify Device History
IMEI (International Mobile Equipment Identity) is the unique identification number of each phone. Using the IMEI number, you can verify whether the device:
- Has not been reported as lost or stolen
- Is not blocked by the carrier (i.e., blacklisted)
- Has a clean history with no record of theft
You can find the IMEI in Settings → General → About, or by dialing *#06# on the dial pad. Verify it on websites like imei.info or directly with your carrier. Any reputable seller will allow you to verify the IMEI before purchase.
3. Warranty Terms — What Exactly Does It Cover?
The warranty is a key indicator of a seller's credibility. Find out:
- How long is the warranty period? (Minimum 6 months, ideally 12+)
- What does the warranty cover? (Hardware defects, battery performance, display?)
- Where is warranty repair performed? (By the seller himself or do you have to send it abroad?)
- Is the warranty confirmed in writing? (Verbal promises are not enough)
iLoveServis operates 11 stores across the Czech Republic, where warranty service can be handled in person and quickly. This is a significant advantage over online sellers without a physical presence.
4. Complaint Policy and Right of Return
When purchasing from a business, the law guarantees you the right to complain and a 14-day right of return when purchasing via an e-shop. Verify:
- How quickly does the seller handle complaints? (Standard is 30 days)
- Is it possible to return the phone within 14 days without giving a reason?
- Who pays for postage in case of a complaint?
- Does the seller have physical establishments where complaints can be handled in person?
5. Device Origin and Refurbishment Process
Ask where the devices come from and what the refurbishment process is. A reputable seller will be happy to explain:
- Where do the iPhones come from (from leases, company fleets, customer buybacks)?
- What components are replaced during refurbishment?
- Is refurbishment performed directly by the seller or externally?
- Is a factory reset and installation of the latest iOS part of the process?
iLoveServis performs the entire refurbishment process with its own certified technicians in Czech repair shops. 15 years of industry experience means proven processes and quality standards.
6. Functional Test Before Handover
When picking up in person, always thoroughly test the device. Check:
- Display: No dead pixels, spots, or touch control issues
- Face ID / Touch ID: Works correctly and quickly
- Cameras: Front and rear — no blur, noise, or defects
- Speakers and microphone: Clear sound without crackling
- Connectivity: WiFi, Bluetooth, mobile data — connect and test
- Buttons: All buttons work correctly
- Charging: Connector works, battery is charging
7. Software Status — Clean iOS Without Defects
Verify that the device is:
- Disconnected from the previous owner's iCloud (Activation Lock off)
- Factory reset
- On the latest iOS version
- Without activation issues
A phone with an active Activation Lock (where the previous owner's iCloud is still logged in) is UNUSABLE — this is the most common trick used by fraudulent sellers at marketplaces.
8. Physical Condition — What Matches the Description?
Compare the actual condition of the device with the description in the advertisement or on the product page:
- Does the category (A, A-, B) match the actual condition?
- Are visible defects (scratches, cracks) indicated in advance?
- Is the display original or replaced? (Original displays are always preferred)
Red Flags — When to Walk Away
These signals indicate a dubious seller:
- Refuses to state battery condition or does not know it
- Does not allow IMEI verification before purchase
- Does not offer any written warranty
- The price is unbelievably low without explanation
- The phone has the previous owner's active iCloud
- The seller has no physical premises or contact phone number
- Pressures for a quick decision ("today only this price")
- Product photos are generic from the internet, not real ones
