Comparing iPhone 15 and iPhone 15 Plus: Design
In terms of overall design, iPhone 15 and iPhone 15 Plus have almost no significant differences as both devices sport the familiar square design like their predecessor, iPhone 14. However, the edges of the devices have been curved at the edges instead of maintaining the sharp, masculine edges of previous generations, which may help users feel more comfortable and ergonomic in hand.

Although the basic product duo appears similar to previous generations of iPhones, iPhone 15 and iPhone 15 Plus are equipped by Apple with the Dynamic Island hole-punch display instead of the notch 'rabbit ears' that has been familiar to many iFans since 2017. This allows users to experience extremely interesting and convenient features in calling, multimedia entertainment, etc., without having to spend too much on the higher-end Pro/Pro Max versions.

Additionally, the color variants of iPhone 15 and iPhone 15 Plus are also identical. This basic iPhone duo marks the introduction of an entirely new Pink color, accompanied by the familiar color options such as Gold, White, Blue, and Black, allowing users to comfortably choose according to their preferences.

So, what's the difference between iPhone 15 and iPhone 15 Plus in terms of design? That lies in the size of the device duo. To illustrate the difference in size between iPhone 15 and iPhone 15 Plus, let's summarize some basic specifications:
- iPhone 15: 5.81 x 2.82 x 0.31 inches
- iPhone 15 Plus: 6.33 x 3.06 x 0.31 inches.

In general, iPhone 15 Plus is for those with larger hands who need a larger device to enhance their experience. However, the only drawback is the heavier weight, making it quite inconvenient to carry in your pocket when moving around. Therefore, with the advantage of being more compact, iPhone 15 will demonstrate flexibility, ease of grip, and a comfortable feeling when putting the phone in your pocket to move around everywhere.
Comparing iPhone 15 and iPhone 15 Plus: Display
In terms of display quality, both iPhone 15 Plus and 15 are equipped with OLED panels with Super Retina XDR technology, combined with a resolution of 2,556 x 1,179 pixels promising to deliver vivid, detailed images. Additionally, the device duo also offers up to 2,000 nits of brightness, ensuring display quality in various lighting conditions, including intense sunlight or bright light.

The difference between iPhone 15 and iPhone 15 Plus lies in the screen size. With a 6.7-inch display, iPhone 15 Plus can show more content, and entertainment, movie-watching, and gaming on this screen will be better than the 6.1-inch display of iPhone 15. However, a larger screen size makes the device bulkier, so if you prefer experiencing on a smartphone with a wide screen, iPhone 14 Plus will be the appropriate answer. Conversely, for those who prioritize compactness and affordability, iPhone 15 will be a better optimized option.
Comparing iPhone 15 and iPhone 15 Plus: Performance
In terms of performance, both iPhone 15 and iPhone 15 Plus are equipped with the Apple A16 Bionic processor - a chip that has previously appeared on the premium smartphone duo iPhone 14 Pro/iPhone 14 Pro Max. Reusing the old processor chip is not a new issue for users because previously, Apple has also done so on iPhone 14 with the A15 Bionic chip of the iPhone 13 Series product line.

Nevertheless, the Apple A16 remains one of the leading powerful processors on smartphones, capable of efficiently handling heavy tasks such as advanced video editing, gaming, etc., for both iPhone 15 and iPhone 15 Plus. Moreover, this enables users to access a new device with robust performance at a reasonable price.

Additionally, iPhone 15 and iPhone 15 Plus also offer three internal memory variants: 128 GB, 256 GB, and 512 GB respectively, allowing users to choose according to their storage needs and financial capabilities.
Comparing iPhone 15 and iPhone 15 Plus: Camera
Unlike previous basic iPhone models, the iPhone 15 and iPhone 15 Plus have received upgrades in camera specifications. Specifically, the device duo features a dual-camera setup with 48 MP + 12 MP resolution instead of the usual 12 MP + 12 MP. This allows you to capture highly detailed and vivid photos.

Additionally, both iPhone 15 and iPhone 15 Plus are equipped with a 12 MP selfie camera on the front. Although there are no improvements in specifications, thanks to the superior image processing capabilities of the Apple A16 Bionic, the devices will still meet the needs of taking sharp, vibrant selfies in various lighting conditions.
Comparing iPhone 15 and iPhone 15 Plus: Battery
In addition to performance and size, battery capacity is also a top criterion that users consider when choosing between the two devices. Naturally, due to its larger size, iPhone 15 Plus has a significantly larger battery than its 'sibling' iPhone 15. According to Apple, iPhone 15 Plus can deliver 26 hours of offline video playback, 10 hours of online video playback, and 100 hours of continuous music playback, while these numbers on iPhone 15 are only 20 hours of offline video playback, 16 hours of online video playback, and 80 hours for music playback.

Therefore, if you need a smartphone with long battery life to meet your essential needs throughout the day, I believe that the iPhone 15 Plus model will still be the better choice.
Which is Better: iPhone 15 Plus or iPhone 15
In summary, if you prefer compact and lightweight devices with an affordable price, then iPhone 15 will be the most suitable choice. However, if you are more concerned about optimizations in user experience, I believe that the larger-sized iPhone 15 Plus will meet your needs better.

Above, I have compared iPhone 15 and iPhone 15 Plus based on the specifications provided by the manufacturer to give you the most comprehensive overview. Will you choose iPhone 15 or iPhone 15 Plus? Leave your comments below for me and everyone to know!
