Pros and Cons

Xiaomi 15

Strengths

The iPhone 15 has been upgraded to a new set of 12 megapixel ultra wide and the new 48 megapixel main camera, which provides better photo quality.

The new auto-Portrait Mode detection feature is pretty sweet, allowing you to capture depth information that can be used later for Portrait Mode photos.

The base iPhone 15's non-zoomed in photos are actually looking a little better, a little more detailed than last year's Pro phones.

Getting the iPhone 15 now means having USB-C, which is the future, and not buying an older model just to save money.

With these subtle improvements, the iPhone 15 feels like an appreciably better phone.

Weaknesses

The camera on the base iPhone 15 has a slightly smaller sensor than the Pro, but it makes up for it with a larger max aperture of F1.6.

Some people might find the lack of significant upgrades to be underwhelming, especially if they're expecting more major changes.

Not all features are available across all models - last year's Pro iPhone doesn't get some features that the new iPhone 15 has, which can be frustrating for those who upgraded last year.

Asus Zenfone 11 Ultra

Strengths

It's a solid Flagship all around with great battery life

No glaring deficiencies across the board

The display looks great, it's much larger than the previous model

The speakers score very good loudness and deliver well-developed mids, clear highs, and even some base

The camera setup is improved, with features like automatic night mode, 8K video recording at 24 FPS, and decent low-light performance

It runs incredibly smoothly with no slowdowns or hiccups, shws through intensive tasks with ease

At least two major software updates and four years of security patches from Asus

Weaknesses

No specific cons listed for this device

Xiaomi 15

Here's a rewritten review of the iPhone 15: The iPhone 15 is an incremental upgrade over its predecessor, with several subtle improvements that make it a more appreciable phone without any major redesigns or new features. The phone boasts a new set of cameras, including a 48-megapixel main camera and a 12-megapixel ultra-wide camera, which can produce a 24-megapixel photo by default. This feature is exclusive to the iPhone 15 and not available on last year's Pro model. The phone also features an improved Portrait Mode detection feature, allowing users to capture photos with depth information that can be converted into Portrait Mode shots later. However, this feature is mysteriously unavailable on last year's Pro iPhone, despite having the same chip and camera setup. Other notable changes include a larger max aperture of F1.6 for better low-light performance and an improved image processing system. The phone also features USB-C instead of Lightning, which is a welcome change. While it may not seem like much at first glance, these subtle improvements make the iPhone 15 a more appreciable upgrade than previous years. If you have an older iPhone or are looking to upgrade from last year's model, I would recommend getting the iPhone 15 for its improved cameras and user experience. However, if you're already happy with your current phone, there's no pressing need to upgrade. Overall, the iPhone 15 is a solid choice for those looking for a reliable and feature-rich smartphone.

Asus Zenfone 11 Ultra

The Asus Zenfone 11 Ultra marks a significant departure from its compact predecessors, embracing a larger form factor that rivals gaming-oriented Rog phones. This shift in strategy raises questions about the future of the Zen phone lineup. Despite this change, the Zenfone 11 Ultra still boasts many hallmarks of a flagship device, including a high-end chipset, improved camera capabilities, and exceptional battery life. In this review, we'll delve into whether this bold new direction is a worthy successor to the Zen phones that came before.
