The iPhone 15 Pro Max (2023) and the iPhone 12 (2020) sit three generations apart, yet both remain widely available in 2026 — one as a discounted flagship, the other as an aging but still-capable classic. This comparison looks at how they stack up on design, performance, cameras, battery, software support, and long-term value. We compared publicly available specifications, expert reviews, and community feedback to help you decide which one deserves your money right now, whether you want cutting-edge power or the cheapest way into iOS with a phone that still handles daily life smoothly.
Choose the iPhone 15 Pro Max if you want the fastest chip, USB-C, 5x optical zoom, ProMotion, and 4+ more years of iOS updates. Choose the iPhone 12 if you want the cheapest new-in-box iPhone that still runs iOS smoothly for calls, social, and light photography.
The iPhone 15 Pro Max is Apple's 2023 flagship — the first iPhone with a titanium frame, USB-C, an Action Button, and the A17 Pro chip built on a 3nm process. It also introduced the 5x tetraprism telephoto lens, exclusive to the Pro Max in that generation, along with ProRes video recording and hardware-accelerated ray tracing for console-style gaming.

The iPhone 12 was Apple's 2020 mainstream flagship — the first iPhone with a flat-edge design (a look Apple still uses today), 5G connectivity, MagSafe, and the Ceramic Shield front glass. It runs the A14 Bionic and still handles iOS 18 well enough for everyday use, which is why refurbished and discounted new units remain popular in 2026.

3.1 Pricing Comparison
Prices for both models fluctuate heavily depending on storage tier, color, seller, and refurbished vs. new condition. The iPhone 12 in 2026 is firmly in the budget tier, while the iPhone 15 Pro Max still commands premium pricing but drops noticeably during major sale events. Rather than chasing a single retailer, it's worth checking live prices across multiple stores at once.

4. Design & Build
Both phones share Apple's flat-edge design language, but that's roughly where the similarities end. The iPhone 15 Pro Max uses a Grade 5 titanium frame with brushed contoured edges, which is lighter than the stainless steel used on earlier Pro models yet more durable in scratch tests. It also replaces the traditional mute switch with the programmable Action Button.
The iPhone 12, by contrast, uses an aluminum frame and glossy glass back. It's noticeably smaller (6.1" vs 6.7") and 57g lighter — a meaningful difference for one-handed use or anyone who dislikes large phones. Both have IP68 water and dust resistance and MagSafe support.
5. Performance
The A17 Pro is roughly three generations ahead of the A14 Bionic. In synthetic benchmarks published by third-party reviewers, the A17 Pro delivers around 2× the single-core and 2–2.5× the multi-core CPU performance, with an even bigger GPU gap thanks to hardware-accelerated ray tracing.
In practice, the iPhone 12 still handles messaging, streaming, browsing, and casual games without lag on iOS 18. Where it struggles is heavy 3D gaming (Genshin Impact, Resident Evil ports), long 4K video recording, and multitasking with many demanding apps. The iPhone 15 Pro Max can run console-class titles like Death Stranding at playable settings — something the iPhone 12 simply cannot do.
6. Camera System
This is one of the biggest gaps between the two phones. The iPhone 15 Pro Max has a 48MP main sensor that supports 24MP default output and 48MP ProRAW, a 12MP ultrawide with macro, and — crucially — a 12MP 5x tetraprism telephoto with sensor-shift OIS. It also supports ProRes video, LOG recording, and Academy Color Encoding System (ACES) workflows for professional post-production.
The iPhone 12 sticks to a classic dual 12MP system (wide + ultrawide) with no telephoto and no macro. Image quality in good light is still respectable, but low-light shots, zoomed photos, and video dynamic range clearly favor the 15 Pro Max. For anyone who cares about photo/video output, the 15 Pro Max is in a different league.
7. Battery & Charging
The iPhone 15 Pro Max ships with a 4,422 mAh battery and Apple rates it at up to 29 hours of video playback. The iPhone 12's 2,815 mAh battery is rated at up to 17 hours — and after several years of use, many original units are down to 80–85% maximum capacity, meaning real-world screen-on times may be noticeably shorter than launch specs suggest.
Both support MagSafe wireless charging (up to 15W) and Qi wireless. Wired charging is capped around 20–27W on both, but the 15 Pro Max uses USB-C, giving you far more cable and accessory flexibility than the older Lightning port on the iPhone 12.
8. Software & Long-Term Support
Software support is arguably the single biggest reason to think twice before choosing the iPhone 12 in 2026. Apple typically supports iPhones with major iOS updates for around five to six years. The iPhone 15 Pro Max should comfortably receive major updates through 2028 and likely beyond, plus features like Apple Intelligence (which requires 8GB RAM — the iPhone 12 doesn't meet that bar).
The iPhone 12 currently runs iOS 18 and will keep getting security patches, but it's near the end of its major-update window and cannot run Apple Intelligence features. If you plan to keep this phone for 3+ years, that gap matters a lot.

9. What Users Are Saying
9.1 Real User Feedback on the iPhone 15 Pro Max
Long-term owners on community forums consistently praise the 5x zoom, USB-C convenience, and the lighter titanium build compared to earlier Pro Max generations. The most common complaints center on Day-1 overheating during heavy 3D gaming (largely resolved via iOS updates), occasional coil whine, and the still-heavy 221g weight. Battery life is widely described as "all-day, easily," even after a couple of years of use. For full owner impressions and long-term reliability notes, see the community write-ups on the iPhone 15 Pro Max user reviews page.
9.2 Real User Feedback on the iPhone 12
iPhone 12 owners in 2026 mostly report that the phone is "still perfectly usable" for daily tasks, especially after a battery replacement. Common frustrations are 60Hz display feeling dated next to newer iPhones, weaker low-light photos, and battery degradation after 3+ years of use. Many users note that pairing it with a MagSafe wallet or grip is a big quality-of-life boost. You can explore aggregated long-term feedback on the iPhone 12 user reviews page.

11. Which One Should You Choose?
Simplify the decision like this: how long do you want to keep this phone, and how much do you rely on the camera? If your answer is "3+ years" or "the camera matters a lot," you should stretch for the iPhone 15 Pro Max — the software support, camera flexibility, and raw performance headroom pay off over time. Also note the wider Apple ecosystem in the cell phones category if you want to weigh other options at similar price points.
If your answer is "1–2 years, then I'll upgrade anyway" or "I just need calls, chat, social, camera basics," the iPhone 12 delivers real iPhone experience at a fraction of the price and is a great gift phone or first iPhone. Just budget for a potential battery replacement.
12. Purchase Timing & Market Cycle Advice
Both phones follow predictable price cycles. The iPhone 15 Pro Max sees the biggest drops right after each new iPhone launch in September, then again during Black Friday/Cyber Monday and post-holiday clearance in January. If you can wait, buying a like-new or refurbished 15 Pro Max in Q4 or early Q1 typically saves the most.
The iPhone 12 is already deep in its discount cycle. Prices are relatively stable now, with modest dips during major sale events. For refurbished units, seller reputation and battery health percentage matter more than shaving off another $10–20 — buy from a seller offering a clear return window and a stated battery health floor (ideally 85%+).

View PriceFrequently Asked Questions
Is the iPhone 15 Pro Max worth it over the iPhone 12 in 2026?
Yes, if you plan to keep the phone for 3+ years or care about photography, gaming, and long-term software support. The 15 Pro Max offers significantly better performance, a 5x telephoto camera, USB-C, ProMotion, and Apple Intelligence support. If you only need basic iPhone functionality and a lower upfront cost, the iPhone 12 remains a reasonable pick.
Will the iPhone 12 still get iOS updates?
The iPhone 12 currently supports iOS 18 and continues to receive security patches. However, based on Apple's historical pattern of roughly five to six years of major iOS updates, it is near the end of its major-update window. Expect it to eventually move to security-only updates while the iPhone 15 Pro Max continues to get full major iOS releases well beyond that.
Can the iPhone 12 run Apple Intelligence?
No. Apple Intelligence requires 8GB of RAM and an A17 Pro or newer chip (or the M-series equivalent in iPads). The iPhone 12 has 4GB of RAM and the older A14 Bionic, so it cannot run Apple Intelligence features. If AI-powered writing tools, image cleanup, and smarter Siri matter to you, you need the iPhone 15 Pro Max or newer.
Is the iPhone 12 battery still good in 2026?
It depends on the individual unit. Most iPhone 12s sold as "used" or "refurbished" in 2026 will have battery health between 80% and 90%. A brand-new certified refurbished unit often comes with a replaced battery at 100%. If battery life is important, look for sellers who list battery health explicitly and offer a return window in case the number is lower than advertised.
Does the iPhone 15 Pro Max overheat?
Early iPhone 15 Pro Max units had reports of noticeable heat during long 3D gaming sessions and while setting up the phone. Apple addressed this largely through iOS updates that improved thermal management. In 2026, most owners report normal warmth under heavy load rather than problematic overheating. Using a case with good thermal dissipation and keeping iOS up to date helps.
Which has a better camera in low light?
The iPhone 15 Pro Max is significantly better in low light. Its 48MP main sensor is larger and gathers more light, and its Photonic Engine and Night Mode processing are several generations more advanced than the iPhone 12's. Photos are cleaner, detail is stronger, and dynamic range is wider. The iPhone 12 still produces usable Night Mode shots but with more visible noise and softness.
Is USB-C really that big of a deal?
Yes, for many users. USB-C lets you use the same cable as most modern laptops, iPads, Android phones, headphones, and accessories. On the iPhone 15 Pro Max it also supports USB 3 speeds (up to 10 Gbps) with the right cable, so transferring large ProRes video files is dramatically faster. The iPhone 12's Lightning port is USB 2 speed and increasingly limited by shrinking accessory support.
Should I buy refurbished or new?
For the iPhone 12, refurbished is often the smart pick because it is the cheapest tier and any remaining new stock may sit on aging batteries anyway. For the iPhone 15 Pro Max, Apple-certified refurbished or reputable retailer refurbished units offer the best value — you get a like-new device with a warranty at a meaningful discount. Always buy from sellers offering a return window and stated battery health.
Which one is better for gaming?
The iPhone 15 Pro Max, without question. Its A17 Pro chip supports hardware-accelerated ray tracing and can run console-class titles like Resident Evil Village and Death Stranding, plus demanding mobile games at maximum settings with ProMotion smoothness. The iPhone 12 handles most casual and mid-tier games fine but will stutter on the heaviest current titles and lacks the 120Hz display gamers now expect.
Conclusion
In 2026, the iPhone 15 Pro Max vs iPhone 12 comparison is really a question of longevity versus affordability. The 15 Pro Max is the clearly better phone in every technical category and will remain relevant for years to come, with cutting-edge cameras, USB-C, ProMotion, and Apple Intelligence support. The iPhone 12 wins on price, size, and simplicity — a solid, familiar iPhone experience for anyone who doesn't need the latest features.
If you can stretch your budget, the iPhone 15 Pro Max is the safer, longer-lasting investment. If you can't — or don't want to — the iPhone 12 still gets the job done in 2026 and delivers real iPhone value at a much lower entry price.
