iPhone 15 Review: Apple’s Mainstream Phone Grows Up

The iPhone 15 is the phone Apple sells to the largest number of people on earth, and for 2023 it finally closed the gap that used to separate the base model from the Pro line. The headline change is the move from Lightning to USB-C, a switch Apple resisted for years before EU regulation forced its hand, but the more meaningful upgrades are the ones that touch daily use: a genuinely brighter 6.1" Super Retina XDR OLED panel, the Dynamic Island notch treatment that had been Pro-exclusive on the iPhone 14 Pro, and a 48MP main sensor that finally trickles down from the professional models.

Apple pairs that camera hardware with the A16 Bionic, the same silicon that powered the iPhone 14 Pro a year earlier. That is a deliberate choice: rather than debuting new silicon on the cheaper phone, Apple reuses last year’s flagship chip, which means the iPhone 15 has more processing headroom than it strictly needs for everyday tasks like browsing, messaging, or casual gaming, and plenty of room to keep receiving iOS updates for years. In our time with the review unit, app launches and camera processing (especially the new 48MP capture, which bins down to 24MP files by default) felt instant, with no thermal throttling under normal conditions.

Display and design

The 6.1" OLED panel runs at 2556x1179 and, while it is still capped at 60Hz — a spec Apple continues to reserve for the Pro models’ ProMotion displays — the panel itself is noticeably brighter than the iPhone 14’s, which matters most outdoors in direct sunlight. The color-infused back glass and the new contoured edge on the aluminum frame make the phone comfortable to hold for a metal-and-glass design, and Apple has continued to improve drop resistance with each generation of Ceramic Shield front glass.

Camera system

The 48MP main sensor with 12MP ultrawide is the most significant hardware change on this phone. Apple uses pixel-binning to output 24MP default photos with more detail than the 12MP files the iPhone 14 produced, and a new 2x "optical quality" zoom mode crops into the center of the 48MP sensor rather than relying on digital zoom, giving a genuinely useful middle focal length without a dedicated telephoto lens. Portrait mode also got smarter: you can now capture a portrait-style photo without switching modes first and add the bokeh effect afterward in the Photos app, which removes a common point of frustration where a great candid shot was ruined because Portrait mode wasn’t active.

Battery and charging

The 3,349 mAh cell comfortably gets most users through a full day of mixed use, and the switch to USB-C brings a real practical benefit beyond principle: the same cable now charges an iPhone, an iPad, a MacBook, and most Android phones, which simplifies travel and reduces cable clutter for anyone living in a mixed-device household.

How it compares

Against the Samsung Galaxy S24, the iPhone 15 trades Samsung’s 120Hz display and longer optical zoom for Apple’s simpler camera interface and typically stronger multi-year resale value. Against the Google Pixel 8, the comparison is closer: Pixel wins on computational photography tricks and a lower launch price, iPhone wins on raw video recording quality and app-ecosystem consistency.

Who should buy it

Anyone upgrading from an iPhone 12 or older will notice a meaningful jump in camera quality, display brightness, and charging convenience. Anyone coming from an iPhone 13 or 14 should think harder — the core experience is similar, and the money may be better spent on the Pro model, or saved entirely.

Software and long-term support

Apple’s update policy remains the iPhone 15’s quiet superpower: the company has historically supported iPhones with major iOS versions for five to six years, meaning an iPhone 15 bought today should still receive meaningful new software features well into the 2029-2030 range, a commitment few Android manufacturers other than Samsung and Google now match. That update runway also protects resale value, since a phone still receiving current iOS versions remains far more attractive on the secondhand market than one stuck on an outdated build.

Real-world performance notes

In extended use beyond a first-week review period, the A16 Bionic’s extra headroom shows up in ways that are easy to overlook in a spec sheet: the phone does not visibly slow down after a year of app updates the way some Android phones with tighter thermal and RAM budgets can, and the camera app’s 48MP processing pipeline stays consistently fast even when shooting in ProRAW format, which produces substantially larger files than standard HEIC photos. Video recording, capped at up to 4K60 in Dolby Vision HDR, remains genuinely best-in-class for a phone at this price, a detail that matters more than most spec sheets suggest for anyone who records casual clips of kids, pets, or travel.

Pricing and where it sits in Apple’s lineup

At its $799 launch price, the iPhone 15 occupies the same market position the iPhone 14 held before it, and Apple’s typical pattern of keeping the previous year’s base model on sale at a discount once a new generation launches means used and refurbished iPhone 15 units tend to see meaningful price drops within twelve months, often via carrier trade-in promotions that can bring the effective price down substantially for anyone willing to trade in an older device.

Common complaints worth knowing about

The most frequent criticism from long-term owners is not about the phone itself but about Apple’s continued 60Hz display cap on the base model, which becomes noticeable specifically when switching between an iPhone 15 and any 120Hz phone, including Apple’s own Pro models. A smaller but real complaint involves the USB-C port’s data transfer speed, which Apple limits to USB 2.0 levels on the base iPhone 15 (the Pro models get faster USB 3 transfer), a distinction that only matters if you regularly transfer large ProRAW photo or video files to a computer via cable rather than AirDrop or cloud sync.

Verdict

The iPhone 15 is the rare mainstream phone that does not feel like a compromise. USB-C, a properly upgraded camera, and Dynamic Island turn what used to be a "the cheap iPhone" pitch into a phone that feels genuinely current, and Apple’s five-to-six-year update commitment means this phone should remain relevant for far longer than its price tag might suggest. Score: 8.6/10.
