iPhone 16 vs iPhone 15: Why the differences are so small
Need a new iPhone? The choice seems simple. The iPhone 16 is the latest model, the iPhone 15 a year older. Done. Or not? Not quite. Because here's the surprise: the differences between the two devices are so minimal that even the most astute tech enthusiasts will have trouble telling them apart.
A higher refresh rate, a slightly better chip, a few watts faster charging—it sounds impressive on paper. In practice, you hardly notice it. In fact, blind testing shows that users often don't even realize which model they're holding. The real question, therefore, isn't which is better, but why Apple keeps the differences so small. The answer reveals a strategy that will hit your wallet harder than you think.

Design and finish: minimal differences
At first glance, the two devices are virtually indistinguishable. Apple adheres to its proven design philosophy, prioritizing evolution over revolution. The aluminum frame and glass back return in both models. The difference lies in the details: the latest generation features an improved version of Ceramic Shield glass. According to the manufacturer, this should be more resistant to drops and scratches, though it remains to be seen how much difference this actually makes in practice.
In terms of dimensions, both smartphones are identical, with their 6.1-inch displays (the Pro versions measure 6.7 inches). Their weight differs by only a few grams—too little to be noticeable in everyday use. Both are IP68 waterproof, meaning they can be submerged in water up to 6 meters for half an hour. Note: This waterproofing cannot be guaranteed for refurbished models due to wear and tear on the seals.
Screen technology: smoother image with the latest
The display story gets more interesting when it comes to the technical specifications. While the previous model was stuck at 60Hz for the standard version, the successor offers an adaptive refresh rate of up to 120Hz. This results in noticeably smoother animations while scrolling and swiping. For those who play a lot of games or watch videos, this could be a welcome improvement.
The OLED panels in both devices deliver the same deep blacks and vibrant colors. The newer model's maximum brightness is slightly higher, which can be especially beneficial outdoors in bright sunlight. In practice, however, most users will notice little difference between the two screens in everyday situations.
Computing power and performance
Chipsets compared
The latest version of the A17 Bionic chip is technically superior to its predecessor's A16 Bionic. Benchmarks show improvements of about 10-15% in pure processing power. This difference can be significant for intensive tasks like video editing or graphics-intensive games. During standard use—think browsing, social media, and messaging—you'll barely notice the performance difference.
Working memory makes the difference
A more significant difference lies in the RAM: 8GB versus 6GB. This extra RAM is especially useful for multitasking. Apps stay active in the background longer, meaning you need to reload less often when switching between applications. For power users who constantly switch between multiple demanding apps, this can be a decisive factor.
Storage options remain unchanged, with 128GB, 256GB, and 512GB available. Neither generation offers memory card expansion, so choose wisely when purchasing.
Camera system: subtle improvements
On paper, both smartphones share the same 48-megapixel main camera. However, the story behind the lens is more nuanced. The image processing in the latest model benefits from improved algorithms and a more powerful processor. This results in better low-light performance, with photos showing less noise and better detail retention.
The ultra-wide and telephoto lenses (only available on Pro models) have received minor updates. For the average smartphone photographer, the differences will be negligible. Professional users may benefit from the improved RAW capabilities and more advanced editing options in the latest version.
Video recording remains a strong point of both devices. 4K recording at various frame rates is standard, with the newer generation offering slightly better stabilization thanks to improved software.
Battery life and charging
Battery capacity differs minimally between the two models, but more efficient hardware allows the newer device to last about an hour longer on a full charge. In practice, this means both smartphones can easily get through a full day of normal use.
Charging power has definitely improved: 27W compared to 20W with wired charging. This saves about 10-15 minutes when fully charging an empty battery. Wireless charging via MagSafe remains limited to 15W on both models. Support for reverse wireless charging – a feature that has been standard on Android competitors for years – is still missing.
Software and future-proofing
Both devices run iOS 17, with the latest model potentially gaining some exclusive features that leverage the extra processing power. Think of more advanced AI features for photo editing or improved speech recognition. Apple is known for its long-term software support, so both models are expected to receive updates for at least another five years.
The reality is that software differences between successive generations are becoming increasingly smaller. Many new features are also being made available for older models, minimizing the difference in user experience.
Price difference and availability
At launch, the suggested retail price of the latest generation was around €1,000, while the previous model is now available starting at around €900. This price difference becomes more significant when you consider refurbished options. A refurbished version of the older model can save you several hundred euros, while maintaining comparable quality to new.
For the latest model, refurbished units will only be available later—expect widespread availability from mid-2025. Until then, you'll be paying top dollar for the latest bells and whistles.
Conclusion: marginal differences, well-considered choice
The technological advances between these two generations are undeniable, but barely noticeable to the average user. The higher screen refresh rate, the slightly faster processor, and the additional RAM are welcome improvements, but not revolutionary leaps forward.
Choose the latest model if you always want the latest technology, play a lot of games, or multitask intensively. However, the older model remains an excellent choice for those looking for a reliable, powerful smartphone without all the latest bells and whistles. Especially refurbished, this device offers excellent value for money. Both devices guarantee years of enjoyment with regular software updates and the typical Apple user experience.
The smartest choice depends on your budget
The differences between the two devices are so minimal that you'll barely notice them in everyday use. For those who really want to get the most out of their devices, the iPhone 16 is the obvious choice. But let's be honest: the iPhone 15 does almost everything just as well for a lower price.
Especially with a refurbished model, you can save hundreds of euros without compromising the user experience. The smartest choice? That depends on your budget and patience – not on the technical specifications.
