There's no such thing as the best iPhone but here are several candidates to the title
One way to find the best iPhone is to provide a response based on the options currently available on the market. Unfortunately, though, what seems like the easy way out is not a one-way street.
Unlike in the first few years of the iPhone era, Apple currently has multiple iPhone models on offer. Walk into an Apple Store (or head on to the company's website) and you can purchase the iPhone 6s, the iPhone 6s Plus, and the iPhone SE. In the second-hand market, the iPhone 5s remains a popular device to this day.
The superb build quality, the great performance, the insane app variety, the improved battery life, and the innovative 3D Touch system, these are all aspects that really make the iPhone 6s one the best high-end phones on the market.
In our Apple iPhone 6s review, we've rated Apple's current-generation flagship device at 9.3/10 points. Our readers, however, have rated it at a highly generous 9.5/10 points. That's the highest user review score for any iPhone.
One reason why the iPhone 6s is probably the best iPhone on the market is the phone's size. The iPhone SE and the iPhone 5s come with 4-inch displays, which may be too small for most people. The iPhone 6s, on the other hand, comes with a large 5.5-inch display and is not a phone that's comfortable phone to use or pocket. The display of the iPhone 6s is 4.7-inch IPS panel running at 750 bt 1334 pixels at a PPI of 326.
On the inside of the iPhone 6s beats the heart of an Apple A9 SoC with a 1.84GHz dual-core Twister CPU and a PowerVR GT7600 GPU. Paired with 2GB of RAM, the A9 can handle everything that you throw at it, offering superb performance overall.
Apple's current-gen phablet comes with a 5.5-inch display, which runs at 1080 by 1920 pixels at a PPI of 401. This is the most pixel-dense iPhone display that Apple has ever made, on equal footing with last year's iPhone 6 Plus, which has the same display specifications.
The camera is another reason why the 6s Plus can be considered the best iPhone currently available. While both the iPhone 6s and the 6s Plus come with a 12MP primary sensor with an F2.0 lens and dual-LED flash, the larger iPhone 6s is the only one that features optical image stabilization (OIS).
In a time when most high-end smartphones come with large displays, the iPhone SE offers a compact alternative: a 4-inch display running at 640 by 1136 pixels that is small enough for comfortable one-handed use.
The iPhone SE is basically a hybrid between the iPhone 5s and the iPhone 6s. The handset is based on the same Apple A9 SoC with 2GB of RAM, and even uses the same 12MP primary camera as the iPhone 6s. However, these components are fitted inside a body that borrows its design and build from the iPhone 5s.

Back in 2010 when we published our Apple iPhone 4 review, we've rated the handset at 9.5/10 points, thinking highly of the phone's display, camera, and build quality.
On the design side, the iPhone 4 was the first iPhone to feature a glass-metal sandwich build, with an aluminum frame separating the front and back glass panels.
In terms hardware, the Apple iPhone 4 came with a 3.5-inch IPS display running 640 by 960 pixels at a PPI density of 330. This is the first display panel that Apple described as 'Retina', claiming that the average user won't be able to identify the individual pixels on the screen and a major. Note that this display is actually denser (although only slightly) than those of the iPhone 6 and 6s Plus.
The iPhone 4 was launched with an Apple A4, a SoC that integrates a single-core 1.0GHz ARM Cortex-A8 CPU and a PowerVR SGX535 GPU. In the memory department, the iPhone 4 featured 8/16/32GB of integrated storage and 512MB of RAM.
In this 4K era, the Apple iPhone 4 camera specifications seem a little underwhelming: the phone came with a 5MP primary camera capable of 720p video capture and a VGA front-facing shooter. At the time, the word selfie had yet to be invented.
