Buying a used iPhone: which model suits you?

Start with your everyday needs, not the model number

First, list three things your next iPhone should do better: last longer, take better photos or avoid storage problems. Check your current usage under Settings → General → iPhone Storage. Also consider whether one-handed use matters more than larger text and plenty of screen space.

For example: Messaging, navigation, family photos and banking do not automatically require a Pro. If you often photograph distant subjects, compare the actual cameras. If you keep long videos on your phone, prioritise storage over a particularly striking colour.

Set an overall budget, including a suitable power adapter, case, screen protector and possible battery service if needed. Compare offers with the same storage and similar condition. Otherwise, a phone may appear cheaper simply because important equipment is missing.

Standard, Plus, mini or Pro: what do the names mean?

These names do not represent identical specifications across generations. Always compare two specific models. A Pro is not better at every feature than every later standard model. Conversely, a higher model number does not automatically replace an older Pro's camera equipment.

Generations such as iPhone 13, 14 and 15 are among the options worth considering used. Availability and configurations change, so our iPhone collection is the right place to compare current offers.

128, 256 or 512 GB: how much storage do you need?

Storage holds apps, photos, videos and downloaded content. You cannot expand an iPhone's internal storage later with a memory card. A larger iCloud plan does not increase it either: some content can be stored in the cloud, but apps and active tasks still need space on the device.

• 128 GB: a starting point if you keep your local collection manageable and store few large videos or offline files.
• 256 GB: more room for a growing photo library, larger apps and downloaded media when travelling.
• 512 GB or more: worth considering for large local libraries or extensive video recording; do not buy solely for the bigger number.

This is planning guidance, not a guarantee. If your current iPhone already uses 115 GB and you do not want to move anything elsewhere, a 128 GB replacement leaves little room. With the same usage and regular tidying, your decision may differ. Allow for expected growth instead of following a blanket recommendation.

Understanding battery health: 90% capacity is not 90% charge

The charge level shows how full the battery is now. Maximum capacity estimates its capacity relative to when it was new. Find battery health under Battery in Settings; the precise submenu name depends on the model and iOS version.

A figure of 90%, for example, does not mean you can only charge the iPhone to 90%. It describes battery ageing. It cannot predict exact daily runtime either: screen brightness, mobile reception, navigation, camera use and apps affect consumption.

A charge cycle is accumulated by using the equivalent of one full battery capacity. Using about half a charge on each of two days can amount to one cycle. This is not the number of times you plug the phone in. Age and temperature also matter.

Alongside the percentage, check for service messages, unexpected shutdowns and unusual heat. If iOS cannot verify the battery, displayed information may be limited or unreliable. Ask questions rather than assuming one figure proves its condition. Calling a used iPhone “refurbished” does not automatically mean it has a new battery; the specific offer determines what is included.

Choose the camera and display around what you photograph

The number of cameras is only part of the decision. An ultra-wide camera captures more of the scene; a telephoto camera helps with certain distant subjects. Digital zoom is not the same as an additional optical focal length. Camera equipment varies by model.

Think about your usual subjects: family photos indoors, landscapes, documents or video. Then compare the candidates' camera features. Megapixels alone cannot reliably tell you the quality of every photo.

Display size and refresh rate are different properties. A higher refresh rate can make movement and scrolling smoother. It does not make the screen larger or replace good readability. If small text is difficult for you, pay particular attention to screen area and adjustable text sizes.

Check Lightning, USB-C, SIM and software beforehand

Many older iPhones, including the iPhone 14 range, use Lightning. The iPhone 15 range has USB-C. The connector shape does not tell you the full data transfer speed. Standard and Pro versions in the iPhone 15 range differ in wired data transfer. Large video transfers depend on both the device and a suitable cable.

For imported devices, also check the regional model number and SIM configuration. Some versions only support eSIM: a digital SIM whose activation must be supported by your carrier. Before buying, establish whether your plan and intended use are compatible.

For essential apps, check their current minimum iOS version and the official compatibility overview. Support today does not guarantee a fixed number of future update years. Individual features may have additional requirements even when the operating system itself runs.

Check the actual used device

1. Match model and storage: Do the details under General → About match your order?
2. Check setup: The phone must not remain locked to a previous owner's Activation Lock. A welcome screen alone does not prove it can be activated freely. Contact the seller if it is locked.
3. Clarify management: If unexpected company or remote management appears, do not dismiss it as a routine setup detail. Responsibility must be clarified.
4. Test the display and controls: Change brightness, look for issues on light and dark backgrounds and test touch input across the whole screen.
5. Test cameras, sound and connections: Take photos with every camera, record and play a short voice memo, and check Wi-Fi and mobile connectivity.
6. Check unlocking and charging: Test Face ID or Touch ID, the available buttons and charging port as appropriate to the model.
7. Read repair information: Depending on model and iOS version, a parts and service history may appear under General → About. Ask for explanations of messages; an absent section is not a comprehensive inspection certificate.

Document any differences from the offer with specific examples and contact the seller. This is a buying and delivery checklist, not a description of a promised internal mac-store24 inspection process.

Compare condition, included items and total costs

Cosmetic grades do not automatically describe battery capacity or every technical characteristic. Read condition, battery information and included items separately. Check whether photos show the actual device or illustrate the model.

The mac-store24 iPhone offers checked currently include the phone and a charging cable; a power adapter is not included. The description of the specific offer remains decisive. Contact our advisers before ordering if anything is unclear.

A cheaper phone makes sense when it meets your needs and any additional costs fit your budget. Compare storage, condition, accessories and any upcoming battery service as well as the purchase price.
