Apple continues to captivate consumers with its iconic iPhone lineup. While the Pro models garner significant attention, the vanilla iPhone models have their dedicated user base. 

Apple's commitment to producing high-quality devices, both in terms of hardware and software, has led to extended upgrade cycles for iPhones. 

In this article, we aim to provide an unbiased, detailed comparison between the Apple iPhone 15 (review) and its predecessor, the iPhone 14, both of which are still available for purchase.

Design and Size:

At first glance, the iPhone 15 and iPhone 14 share a strikingly similar physical footprint, making them nearly indistinguishable in terms of size and shape. 

However, subtle differences come to light upon closer examination. The iPhone 15 stands out with its new colors and the adoption of the Dynamic Island, previously exclusive to the Pro models, giving it a more contemporary appearance.

Both phones sport a 6.1-inch display, with the iPhone 15 boasting a slightly higher resolution and an improved screen-to-body ratio of around 86.4%. 

While the difference in resolution is hardly noticeable, the iPhone 15's rounded chamfer on its aluminum middle frame enhances handling comfort.

Materials and Build:

Both the iPhone 15 and iPhone 14 feature aluminum frames, Gorilla Glass on the back, and a Ceramic Shield on the front, providing durability and protection.


Additionally, both models carry the same IP68 rating, certifying their ability to withstand submersion in up to 6 meters of fresh water for 30 minutes.


The display is a key element of any smartphone, and while both the iPhone 15 and iPhone 14 feature 6.1-inch Super Retina XDR OLED displays certified for HDR10 and Dolby Vision, there are notable differences. Regrettably, Apple has continued to limit the refresh rate of its vanilla iPhone models to 60Hz.


However, the iPhone 15 distinguishes itself with a significant improvement in brightness. It reaches 1643 nits of maximum brightness when exposed to strong external light, whereas the iPhone 14 maxes out at 804 nits. 

The slightly higher resolution of the iPhone 15's display (1179 x 2556 pixels) compared to the iPhone 14 (1170 x 2532 pixels) is hardly perceptible, but the transition from the notch design to the Dynamic Island on the iPhone 15 brings it in line with the Pro models, offering a more modern look.

Battery Life:

Apple has managed to fit a slightly larger battery into the iPhone 15, increasing its capacity from 3279 mAh (iPhone 14) to 3349 mAh, without altering the device's dimensions or weight. 

Furthermore, the A16 Bionic chip inside the iPhone 15 is based on a more efficient 4nm process compared to the A15 Bionic (5nm) found in the iPhone 14.


Combined with architectural advancements and likely improved display efficiency, this results in a noticeable bump in battery endurance.

In testing, the iPhone 15 outperformed the iPhone 14, achieving an overall battery endurance of 98 hours compared to the iPhone 14's 90 hours. 

Particularly, the iPhone 15 demonstrated longer runtimes during on-screen tasks such as web browsing and video watching, essential aspects of battery endurance.

Charging Speed:

Both the iPhone 14 and iPhone 15 are equipped to charge from zero to 50% in just 30 minutes with a 20W charger, according to Apple's claims. 

In real-world testing, both models exceeded this expectation, with the iPhone 14 reaching 60% and the iPhone 15 hitting approximately 58% in half an hour.


While neither phone can be considered particularly fast in terms of charging, the iPhone 14 has a charging taper-off that is less aggressive towards the end of the cycle compared to the iPhone 15. 

Consequently, the iPhone 14 manages to complete a full charge slightly faster, taking 1 hour and 31 minutes, compared to the iPhone 15's 1 hour and 50 minutes. 

It's worth noting that charging curve behavior could change with future iOS updates.

Speaker Quality:

Both the iPhone 14 and iPhone 15 feature hybrid stereo speaker setups, combining a dedicated bottom-firing speaker with an amplified earpiece.

These setups deliver excellent sound quality, characterized by clean mids and highs and even some lows.


Interestingly, the older iPhone 14 outperforms the iPhone 15 in terms of speaker loudness. 

While the exact reason for this difference is speculative, it's worth noting that the iPhone 14 achieved a "VERY GOOD" score in loudness, while the iPhone 15 earned a "GOOD" rating.


The heart of any smartphone is its processor, and both the iPhone 14 and iPhone 15 house powerful Apple-designed chips. 

The iPhone 14 features the A15 Bionic chip built on a 5nm process, while the iPhone 15 boasts the newer A16 Bionic chip fabricated using a more efficient 4nm process.


The CPU performance improvements of the A16 over the A15 are incremental, but the move to LPDDR5 RAM provides a substantial boost in overall performance and responsiveness.

In the GPU department, both models have five GPU cores, benefiting from the higher memory bandwidth available on the A16 chipset. 

Apple's Neural Engine, responsible for on-board machine learning tasks, is also similar in both models, boasting increased performance on the A16 chip. 

In practical terms, the A16 is approximately 15% more powerful than the A15.

Camera Capabilities:

The camera systems in the iPhone 14 and iPhone 15 differ significantly, with the iPhone 15 introducing an all-new 48MP main camera. 

Utilizing computational photography and stacking techniques, the iPhone 15 produces 24MP stills that offer greater detail than the 12MP cameras on previous iPhones, thanks to an enhanced version of Apple's Photonic Engine.

While the iPhone 15 lacks a dedicated optical zoom camera, its high-resolution main camera allows for high-quality digital crops and zooms, potentially surpassing the iPhone 14 in this regard. 

Both models share a 12MP ultrawide camera on the back, lacking features like autofocus found on the Pro models.

The selfie cameras on both models are likely identical, with 12MP sensors and autofocus capabilities. 

The iPhone 15's 24MP default photos from the main camera exhibit exceptional sharpness and detail, while the 2x digital zoomed photos also benefit from the higher main camera resolution.

The color processing and science developed by Apple over the years remain consistent on both phones, offering slightly more muted colors compared to many modern Android phones, catering to individual preferences.

Both models excel in video capture, offering up to 4K resolution across all cameras with optional EIS and expanded dynamic range through Smart HDR and HDR video capture. ProRes video remains exclusive to the iPhone Pro models.

In low-light scenarios, both the iPhone 15 and iPhone 14 deliver impressive results, with a slight edge given to the iPhone 15.

One notable drawback in Apple's night mode is the inability to manually activate it; users can only toggle it off. 

Additionally, in default Auto mode, the Night mode may not activate as frequently as desired, a criticism applicable to both models.


The iPhone 15 and iPhone 14 each cater to distinct consumer preferences and priorities. The iPhone 14, being more budget-friendly, retains

its relevance in 2023, offering fast charging, slightly louder speakers, and competitive hardware. 

On the other hand, the iPhone 15 introduces several enhancements, including a superior 48MP main camera, USB Type-C connectivity, a brighter display, improved battery life, and a faster chipset.

Ultimately, the choice between these two models depends on individual needs and preferences. 

The iPhone 15 presents a compelling option for those seeking the latest features and longer software support. 

However, the iPhone 14 continues to provide an excellent smartphone experience at a more accessible price point. 

Apple's decision to offer both models ensures a diverse range of choices for consumers, catering to both the tech-savvy and those seeking simplicity.
