The current iPhone models and how to tell them apart
Apple releases new iPhone models almost every year, and the current lineup includes the iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max. If you are shopping for a new phone or trying to figure out which model you already own, the easiest way is to look at the back of the device — Apple prints the model name in small text near the bottom.
The main differences between models come down to screen size, camera quality, and processing power. The standard iPhone 16 has a 6.1-inch screen, while the Plus version is larger at 6.7 inches. The Pro models have better cameras, faster processors, and slightly different designs, with the Pro Max being the largest at 6.9 inches. All current models work with the same chargers and run the same operating system, so the choice mostly depends on your budget and how much screen space you want.
If you own an older iPhone, the model name tells you roughly when it was released. The iPhone 15 came out in 2023, the iPhone 14 in 2022, and so on. Older models still work fine for most tasks, but they stop receiving software updates after five to seven years, which means they eventually lose access to new features and security patches.
Key Takeaways
- The model name is printed on the back of the phone in small text near the bottom, making it the fastest way to identify what you own.
- Current iPhone models are the 16, 16 Plus, 16 Pro, and 16 Pro Max, with the main differences being screen size and camera quality.
- You can also find the model name in Settings by opening Settings, tapping General, then About — it appears next to "Model".
- Older iPhone models still work but eventually stop receiving security updates, usually five to seven years after release.
Finding your model number if the text is worn off
If the back of your phone is too scratched or faded to read, you can find the model name through the Settings app. Open Settings, tap General, then tap About. Look for the line that says "Model" — next to it you will see the name of your iPhone.
This same screen also shows your iOS version, which tells you whether your phone is up to date. If you see a notification that says "iOS 18.2 available" or similar, your phone can still receive updates. If the iOS version has not changed in over a year, your model is likely too old to receive new versions.
What the Pro and Plus labels mean
Pro means the phone has professional-grade cameras and a faster processor than the standard model. Pro phones also have a slightly different design — the camera bump is larger, and the edges are made of stainless steel instead of aluminum. If you take a lot of photos or videos, or if you use apps that demand high processing power, a Pro model is worth the extra cost. If you mostly use your phone for texting, browsing, and social media, the standard model does the same job.
Plus means the phone is straightforward larger — it has a bigger screen but the same camera and processor as the standard model. The Plus is useful if you watch videos on your phone often, play mobile games, or just prefer a larger display. The trade-off is that it is heavier and harder to use one-handed.
The Pro Max combines both: it is the largest screen and has the professional cameras. It is the most expensive option and is mainly for people who want the absolute best of everything.
How to check if your iPhone is still getting updates
Open Settings, tap General, then tap Software Update. If you see a message that says "iOS is up to date," your phone is current. If you see a version number with "available" next to it, your phone can still receive updates — tap read and Install to get the latest version.
If the Software Update screen says your phone cannot update to the latest iOS version, it means your model is no longer supported. This does not mean your phone stops working when ready, but it will gradually lose access to new features and security patches. Most people replace their phone within a year or two after it stops receiving updates, though older phones can still be used for basic tasks.
Understanding the difference between model name and model number
The model name is what you see printed on the back — "iPhone 16 Pro," for example. The model number is a code like "A2846" that appears in the Settings app under About. You will rarely need the model number unless you are contacting Apple support or looking up very specific technical information.
Retailers and Apple's website use the model name, not the number, so when you are shopping or comparing phones, focus on the name. The model number is mainly useful for Apple technicians and repair shops.
What to look for when buying a used or refurbished iPhone
If you are considering a used iPhone, the model name tells you how old it is and whether it will still receive updates. An iPhone 15 or 16 will get updates for several more years. An iPhone 13 or 14 will likely get updates for two to four more years. Anything older than iPhone 13 is approaching the end of its update cycle.
Ask the seller to show you the Settings screen with the model name and iOS version visible. This proves the phone actually turns on and shows you exactly what you are getting. Also check the battery health by opening Settings, tapping Battery, then Battery Health and Charging — if the battery is below 80 percent, the phone may need a replacement battery soon, which costs money.
Why Apple releases so many models at once
Apple releases four models each year to give people choices based on budget and preference. The standard model is the least expensive and works well for most people. The Plus is for people who want a bigger screen without paying for Pro cameras. The Pro is for people who want better cameras and do not need the extra size. The Pro Max is for people who want everything.
This strategy means almost everyone can find an iPhone that fits their needs and budget. It also means that older models drop in price when new ones come out, so you can save money by buying last year's model instead of this year's.
Frequently Asked Questions
Can I use an iPhone 12 in 2025?
Yes, an iPhone 12 still works fine for calls, texts, email, and most apps. It will continue to receive security updates through 2025 and possibly 2026. After that, it will still work but will gradually lose access to new features and security patches.
What is the difference between iPhone 16 and iPhone 16 Pro?
The main differences are the camera system (Pro has better zoom and low-light performance), the processor speed (Pro is slightly faster), and the design (Pro has stainless steel edges). For everyday use like texting and social media, both phones perform identically.
Is the Plus model worth buying over the standard iPhone?
Only if you watch a lot of video on your phone or prefer a larger screen. The Plus has the same camera and processor as the standard model, so the only advantage is size. If you use your phone one-handed or do not watch much video, the standard model is lighter and easier to handle.
How do I know if my iPhone is too old to buy?
If a phone is older than iPhone 13, it will stop receiving updates within the next year or two. Check the Settings app to see the current iOS version — if it cannot update to the latest version, the phone is near the end of its life. Phones older than iPhone 11 are generally not worth buying used.
Do all iPhones use the same charger?
All current iPhones (iPhone 15 and newer) use USB-C chargers. Older models use Lightning chargers, which are different. If you are buying a used phone, make sure you have the right charger or budget for a new one.
