Compare available iPhone generations around budget, display and photography needs. Choose a generation, then check the exact product storage, SIM type, condition and warranty.
The right iPhone is not necessarily the newest Pro Max. Start with a comfortable size, your current storage use and the photos you usually take. The generations below help narrow your choice before comparing individual models.

For used phones, battery health, components and actual condition can matter more than a later generation. For new phones, check the market version, SIM support, accessories and warranty; products with the same name are not automatically identical.
iPhone Air prioritizes a thin body and a 6.5-inch display. It has A19 Pro but a single rear camera and no SIM tray; consider your photography and eSIM needs before choosing.
TechBuy currently offers iPhone 18 Pro and Pro Max with A20 Pro, ProMotion up to 120Hz and three 48MP rear cameras. Pro has a 6.3-inch display and Pro Max 6.9 inches; choose around handling, screen space and storage needs.
Standard iPhone 17 already has ProMotion up to 120Hz. The Pro models add A19 Pro and three 48MP cameras; choose around telephoto, video work and size rather than buying Pro only for ProMotion.
iPhone 16 and Plus use A18; Pro models add A18 Pro, ProMotion and 5x telephoto. Pro moves to a 6.3-inch display and Pro Max to 6.9 inches, making handling as important as specifications.
The entire iPhone 15 generation moves to USB-C, but standard and Plus differ from Pro in chip, display and cameras. Compare the 3x telephoto on Pro with 5x on Pro Max, not just their sizes.
The four iPhone 14 models differ in more than price. The standard and Plus models pair A15 Bionic with dual cameras; Pro and Pro Max add A16 Bionic, ProMotion up to 120Hz and a telephoto camera. Start with the size that feels comfortable, then weigh the features you actually need.
iPhone 13 offers mini for small-phone buyers, a standard 6.1-inch model and two Pro models with ProMotion. Sharing the A15 Bionic name does not make their displays, cameras or handling identical.
The iPhone 12 generation brings OLED and 5G to the standard model. Choose Pro when you need a telephoto camera, or Pro Max when a larger display is worth a larger device.
Consider iPhone 11 when budget matters more than OLED or 5G. With an older used device, prioritize the condition of the actual unit over color or the lowest advertised price.
Each generation starts at the lowest price among its in-stock variants offered for sale. Open a generation for its comparison, or an individual product for storage, finish, SIM type and condition.
Frequently asked questions
Should I choose standard, Plus, Pro or Pro Max?
Start with standard for medium size and budget. Plus prioritizes screen space; Pro adds camera and display features depending on generation; Pro Max is generally larger. Not every generation offers all four, so compare the exact family.
How should I compare used and new iPhones?
Compare the storage and features you need, then condition, battery, accessories and warranty. Inspect the actual used device; new phones still require checking market version and SIM support. Do not draw conclusions from the lowest prices of different configurations.
Which storage capacity should I choose for iPhone?
Check storage use on your current phone and leave room for new files. Consider more capacity for many videos or games. The table lists only in-stock capacities; internal storage cannot be upgraded after purchase.
Does the starting price apply to every variant?
No. Starting prices are taken automatically from the lowest-priced in-stock variant offered for sale. Storage, color, SIM type and condition may change the price. Select the exact product options to see the final amount.
What should I confirm before ordering an iPhone?
Check the model, capacity, SIM type, condition, accessories and warranty on the listing. For eSIM, confirm carrier support for your plan. On a used device, also check battery health, Face ID and components before accepting it.
