Apple's gone a bit nuts this year with the number of phones it is offering consumer. In fact, Apple is offering a total of five iPhone series inside 2017 and going into 2018; the iPhone X, the iPhone 8 series, last year's iPhone 7 series, the iPhone 6s series, and the iPhone SE.

Add in every "Plus" model to those and you're looking at eight different handsets.

Here we're going to compare the new iPhone 8 against its oldest available equivalent; the iPhone 6s.

And truth be told, at this point both these phones are going to be more readily available than the brand spanking iPhone X - that's a situation that might not change anytime soon either. According to KGI Securities analyst Ming-Chi Kuo, Apple could see record pre-orders of between 40-50 million, but it could struggle to keep up with this demand until well inside 2018 due to component supply bottlenecks.

A report from the WSJ, which corroborates with Kuo's assertions, cites multiple unnamed sources who explain the reason for this setback. Allegedly, Apple's Face ID 3D scanning tech is the source of the problem, which also lines up with what Kuo has said. The WSJ's sources say the tech requires two key components working in tandem, but one of these is presently only being manufactured by the tens of thousands of units per day - a far cry from the hundreds of thousands needed to meet demand.

iPhone 8 vs iPhone 6s: Specs

Here’s the specs for the iPhone 8:

• Display: 4.7-inch display with a 1334x750-pixel resolution at 326ppi

And here’s the specs for the iPhone 6s:

• Display: 4.7-inch Retina HD display with 1334x750 resolution at 326 pixels per inch (ppi)
• Dimensions: 138.3mm x 67.1mm x 7.1 mm
• Weight: 143 grams
• Storage: 32 or 128GB

iPhone 8 vs iPhone 6s: Display & Design

As with the iPhone 7 as well, there’s absolutely no difference in the displays of the iPhone 8 and iPhone 6s. Each offers a 4.7-inch display with a 1334x750-pixel resolution at 326 ppi. Both phones also offer 3D Touch. However, the iPhone 8 features a True Tone display, which matches the ambient light of the room you are using it in, and you’ll notice a difference because of that.

The iPhone 6s comes in either 32 or 128GB while the iPhone 8 comes in either 64 or 256GB. A huge difference is also in the chip each phone packs. The A11 Bionic chip in the iPhone 8 will run absolute circles around the A9 found in the iPhone 6s.

As for the design, both feature aluminum bodies with rounded corners, but the iPhone 8 adds a nice glass back paneling to it (for wireless charging capabilities). This gives it a shine like the iPhone 4 used to have. Because of the glass back, the iPhone 8 is just a tad thicker and heavier than the iPhone 6s–but not by much. The iPhone 8 also does away with the antenna bands on back of the iPhone 6s, so it’s a cleaner design.

Another advantage the iPhone 8 has is its Splash, Water and Dust Resistant, whereas the iPhone 6s is not. As far as color options go, the iPhone 6s offers four options, while the newer iPhone 8 only offers three.

iPhone 8 vs iPhone 6s: Battery

The iPhone 8 has a bit of a larger battery than the iPhone 6, at 1821 mAh versus 1715 mAh. However, Apple says both phones basically have the same battery life for most things (thanks to the A11 being a bit more power efficient than the A9). Here’s how the battery life compares between the two in Talk Time, Standby Time, Internet Use, Video Playback, and Audio Playback:

• Talk time: iPhone 8 – 14 hours. iPhone 6s – 14 hours.
• Internet use: iPhone 8 – Up to 12 hours. iPhone 6s – Up to 10 hours.
• Video playback: iPhone 8 – Up to 13 hours. iPhone 6s – Up to 11 hours.
• Audio playback: iPhone 8 – Up to 40 hours. iPhone 6s – Up to 50 hours.

And don’t forget, the iPhone 8 offers wireless charging, whereas the iPhone 6s does not.

iPhone 8 vs iPhone 6s: Camera

Both the iPhone 6s and iPhone 8 have the same megapixels in the rear cameras, however, the sensors in the iPhone 8’s rear camera offers optical image stabilisation, wide colour capture for photos and Live Photos, and quad-LED True Tone flash with slow sync. As for the front camera, the iPhone 8 offers a 7MP sensor (versus 5MP in the 6s) and features 1080p HD video recording (versus 720p HD in the 6s).

iPhone 8 vs iPhone 6s: Cost & Verdict

And then there is the cost. Unlocked the 4.7-inch iPhone 8 will cost £699 (64GB) and £849 (256GB). The iPhone 6s will cost £449 (32GB) and £549 (128GB). That £250 and £300 premium for the iPhone 8 does get you a heck of a lot more: a better CPU, better camera, wireless charging, and more storage.
