Quick Verdict
The iPhone 15 Plus is the iPhone 15 stretched to a 6.7-inch body — same A16 Bionic, USB-C 2.0, Dynamic Island, 48MP main + 12MP ultrawide, 60Hz display, no Action Button — but with a meaningfully larger 4,383mAh battery that delivers the longest-lasting battery in the iPhone 15 family. Like the standard 15, it does NOT support Apple Intelligence — the A16 doesn't meet the iOS 18.1+ requirement. Buy this if you want the big-screen Apple experience with two-day battery life and don't care about AI features or ProMotion; skip it if Apple Intelligence matters, if you want a real telephoto, or if the $100 extra over the standard 15 isn't worth the bigger screen+battery.
Pros reviewers agree on
Strengths consistently called out across sources
- Best battery life in the iPhone 15 family — 4,383mAh + A16 efficiency reliably delivers 1.5-2 day endurance
- USB-C, Dynamic Island, 48MP camera and 2x lossless zoom all carry over from the standard iPhone 15
- 6.7" Super Retina XDR OLED at 2000-nit peak — same panel as the Pro Max minus ProMotion 120Hz
- Contoured aluminum frame, color-infused glass back — comfortable for a big phone at 201g
- $899 starting (128GB base) — only $100 over the standard iPhone 15 for the bigger screen and battery
Cons reviewers agree on
Weaknesses flagged across multiple sources
- NO Apple Intelligence — A16 doesn't qualify for iOS 18.1+ AI features; same exclusion as the standard iPhone 15
- USB-C 2.0 only (480Mbps) — Pro models get 10Gbps USB-C 3.0
- 60Hz display only, no ProMotion — feels meaningfully less smooth than the Pro Max
- No telephoto lens — relies on 2x sensor crop from the 48MP main
- No Action Button (traditional mute switch retained)
What reviewers disagree on
Points where expert verdicts diverge — weigh based on your priorities
- Is the $100 step-up from iPhone 15 worth it — Forbes/Reviewed say yes for the bigger battery alone; some say spend $200 more on the Pro instead
- vs iPhone 15 Pro Max — Plus wins on price + lighter weight; Pro Max wins on Apple Intelligence, ProMotion, 5x periscope, USB-C 3.0
- Apple Intelligence exclusion impact — major dealbreaker for some, irrelevant for casual users

Detailed Breakdown
6.7-inch Super Retina XDR OLED at 60Hz with 2000-nit peak. Same panel as the Pro Max minus ProMotion. Contoured aluminum frame at 201g — comfortable for a big phone.
- 6.7" Super Retina XDR OLED, 2796×1290, 60Hz refresh, 2000-nit peak HDR — same panel size as Pro Max, no ProMotion 120Hz.— Notebookcheck
- Contoured aluminum frame with rounded edges — significantly more comfortable in hand than the boxier iPhone 14 Plus.— WIRED
- Dynamic Island carries over from the 14 Pro — same software experience as the Pro Max in the cheaper body.— The Verge
- Color-infused glass back in pastel colors — premium-looking for a non-Pro iPhone.— Engadget
- 201g aluminum body is meaningfully lighter than the Pro Max's 221g titanium — easier to hold one-handed despite the big footprint.— WIRED
- 60Hz display on a 6.7" phone feels especially dated — the Plus's biggest non-Pro compromise.— WIRED
Same camera hardware as the iPhone 15: 48MP main with 2x lossless sensor crop + 12MP ultrawide + 12MP TrueDepth selfie. No real telephoto. Excellent for casual photography.
- 48MP main (f/1.6) + 12MP ultrawide (f/2.4) + 12MP TrueDepth selfie — identical to the iPhone 15.— Notebookcheck
- 2x lossless zoom via 48MP sensor crop (12MP output) — best telephoto substitute on a non-Pro iPhone but no real optical telephoto.— WIRED
- Excellent daylight photos with Apple's signature natural color processing — perfect for everyday social media use.— Digital Trends
- Front-facing 12MP TrueDepth selfie is 'one of the best for TikTok selfie rants' (WIRED).— WIRED
- Caps short of the Pro Max for distant shots — no 5x periscope, no 3x telephoto, just main and ultrawide.— Engadget
A16 Bionic (4nm) from the iPhone 14 Pro — fast and efficient for everyday use. The dealbreaker: NO Apple Intelligence support on iOS 18.1+, the only family member alongside the standard iPhone 15 excluded.
- A16 Bionic + 6GB RAM — same chip as the iPhone 14 Pro, plenty fast for daily use.— Notebookcheck
- NO Apple Intelligence support — A16 doesn't meet the iOS 18.1+ requirement. Genmoji, Writing Tools, smarter Siri all locked out.— MacRumors AI thread
- Performance remains excellent in 2026 — A16 handles iOS 18 smoothly for everyday use, just without the AI features.— YouTube — iPhone 15 Plus 2025 review
- Apple Intelligence exclusion makes the iPhone 15 Plus future-limited — Apple's AI roadmap will continue to leave A16 behind.— Reddit r/apple
The iPhone 15 Plus's standout: 4,383mAh battery delivers the best battery life of the iPhone 15 family, reliably hitting 1.5-2 days for moderate use. USB-C 2.0 only — Pro gets 10Gbps.
- 4,383mAh battery — biggest in the iPhone 15 family by 1,000+ mAh over the standard 15. Reliably hits 1.5-2 day endurance.— Notebookcheck
- WIRED: 'battery life doesn't make me fear leaving the house with a USB-C cable' — the Plus is the iPhone 15 battery champion.— WIRED
- Long-term owners report 7-8 hours of screen-on time typical — best in the iPhone 15 lineup, even beating the Pro Max in some real-world tests.— Reviewed
- USB-C 2.0 (480Mbps) only — Pro models get 10Gbps. Fine for daily charging and AirPods sync, slow for large 4K video transfers.— WIRED
- MagSafe 15W wireless + Qi 7.5W + 20W wired — same charging speeds as the standard iPhone 15 and the 14 Plus.— Notebookcheck
$899 starting (128GB base) — $100 over the iPhone 15 for the bigger screen + better battery. At $600-750 used in 2026 it's the best non-Pro big-screen iPhone, but the Apple Intelligence exclusion increasingly hurts its long-term value.
- Launched at $899 / 128GB — same starting price as the iPhone 14 Plus, only $100 over the standard iPhone 15.— The Verge
- Best non-Pro big-screen iPhone at $600-750 used in 2026 — bigger battery + same iPhone 15 features for $100 more than the standard 15.— YouTube — iPhone 15 Plus 2025
- vs iPhone 15 Pro Max ($1,199): Plus loses on Apple Intelligence + ProMotion + 5x periscope + USB-C 3.0 + titanium, wins on price + lighter weight.— Phone Arena
- vs Pixel 8 ($699) and Nothing Phone (2) ($600) — iPhone 15 Plus wins on chip + ecosystem; Android rivals win on price + AI features.— Forbes
- Apple Intelligence exclusion hurts long-term value — many 2026 buyers prefer the standard 15 (cheaper) or 15 Pro (with AI), making the Plus an awkward middle pick.— Reddit r/apple AI thread
Long-term Verdict
What creators say after 30, 100, or 365 days of real-world use — the post-honeymoon reality that launch-day reviews can't cover.
Long-term reviews land on the iPhone 15 Plus as the battery champion of the iPhone 15 family — even outlasting the Pro Max in some real-world tests. The Apple Intelligence exclusion is the recurring concern that limits its long-term feature value.
- Long-term battery: 4,383mAh + A16 efficiency reliably hits 1.5-2 days for moderate use, often outlasting the Pro Max in real-world endurance.— Reviewed
- 6 months in: A16 still feels fast, USB-C + Dynamic Island + 48MP remain the standout improvements over the iPhone 14 Plus.— Engadget follow-up
- Apple Intelligence long-term lockout: A16 doesn't qualify for iOS 18.1+; Genmoji, Writing Tools, smarter Siri and ChatGPT integration all absent.— MacRumors AI thread
- Long-term display feels increasingly dated — 6.7" at 60Hz is harder to tolerate next to 120Hz Pro screens or Android rivals as the years pass.— WIRED
- Long-term USB-C 2.0: fine for everyday charging and AirPods; creators who needed fast SSD transfers regret not buying the Pro.— WIRED
- Aluminum frame long-term: contoured edges hold up well; color-infused glass back stays vibrant after 1-2 years.— Engadget
- Long-term software runway: 6-7 years of iOS updates expected (through ~iOS 22-23), though without Apple Intelligence the updates feel less rich.— MacRumors
- iPhone 15 Plus is the rare Apple product where 'big = better battery' actually delivered — long-term battery health stays high with optimized charging.— Reviewed
- vs iPhone 16 Plus (which DOES get Apple Intelligence): iPhone 15 Plus owners feel left behind on the AI roadmap by 2025.— Reddit r/apple
- Long-term verdict: best non-Pro big-screen iPhone yet — but the AI exclusion increasingly makes the 15 Pro the smarter long-term buy at $200-300 more.— YouTube — iPhone 15 Plus long-term
Real-World Tests
Battery drain runs, durability tests, camera shootouts, and gaming benchmarks — the numbers that only video testers capture.
Hands-on tests confirm the iPhone 15 Plus's battery dominance: 4,383mAh + A16 efficiency delivers 7-8 hours of SOT typical, sometimes outlasting the Pro Max. USB-C 2.0 caps file transfers, 60Hz display feels dated on a 6.7" screen, and the 48MP camera matches the standard iPhone 15.
