Should I Upgrade to the iPhone 7?

It seems as soon as you get used to your iPhone, Apple releases a new one. As technology advances, Apple is constantly under pressure to release a better device that can compete with other top brands such as Samsung, LG, Motorola, and Google. While we await the next iPhone release, let’s compare the iPhone 6, 6s and iPhone 7. What makes them different and should you consider upgrading your device or should you just wait for the iPhone 8?

It’s easy to mix up these three phones with a quick glance as they all use the same core design Apple introduced with the iPhone 6 in 2014:

  • iPhone 6 – 138.1 x 67 x 6.9 mm (5.44 x 2.64 x 0.27 in) and 129 g (4.55 oz)
  • iPhone 6S – 138.3 x 67.1 x 7.1 mm (5.44 x 2.64 x 0.28 in) and 143 g (5.04 oz)
  • iPhone 7 – 138.3 x 67.1 x 7.1 mm (5.44 x 2.64 x 0.28 in) and 138 g (4.87 oz)

The iPhone 6 uses Series 6000 aluminum, which is prone to bending, but this is fixed by the iPhone 6S which uses much stronger Series 7000 aluminum. Meanwhile, the iPhone 7 retains this stronger chassis while adding water resistance (allow 30 minutes full submersion at depths of up to one meter) and a fixed home button with haptic (vibration) feedback which eliminates an infamous point of failure.

The iPhone 7 has external dual stereo speakers after Apple beefed up the earpiece speaker. This makes a dramatic difference to audio and is ideal for listening to audiobooks and podcasts.

But you also pay a price for the iPhone 7 as Apple has removed the headphone jack. If you use wireless headphones this won’t matter, but if you prefer wired you will need adapters and you can’t listen to music and charge your phone at the same time without an additional adapter. Apple says its removal allowed it to add water resistance, but Samsung achieved this while keeping the jack (at least for now).

The iPhone 7 also drops the iPhone 6S’s Space Grey color option leaving Rose Gold, Gold, Silver, Black and (for just 128GB and 256GB options) introducing the truly dreadful Jet Black – avoid it like the plague!


Apple’s inability to source OLED panels in large enough quantities for its iPhone range has long given rivals a welcome advantage. As such on paper, the iPhones’ screens look rather pathetic, but there is more to these raw specifications than meets the eye:

  • iPhone 6, iPhone 6S and iPhone 7 – 4.7-inch LED-backlit IPS LCD, 1334 x 750 pixels (326 ppi), 65.6% screen-to-body ratio

Firstly Apple has been making these panels brighter and more color accurate with each generation. For example, the iPhone 7 is 25% brighter than the iPhone 6S (which was already brighter than the iPhone 6) and has support for a wide (P3) color gamut. It’s not OLED and the resolutions are low by today’s standards but iPhones represent the best LCD panels you’ll find.

In addition to this the iPhone 6S and iPhone 7 offer 3D Touch which gives users pressure sensitive ‘peek and pop’ shortcuts. It’s hard to tell what is and isn’t 3D Touch enabled which stops the system being intuitive, but where it does work (notably previewing emails and URLs and shortcuts on app icons) there are signs of its undoubted potential.


Apple keeps setting new records:

  • iPhone 6 – Apple A8 chipset: Dual-core CPU,  Quad core GPU, 1GB of RAM
  • iPhone 6S – Apple A9 chipset: Dual-core CPU, GPU: Six Core GPU, 2GB of RAM
  • iPhone 7 – Apple A10 Fusion chipset: Quad Core CPU, Six Core GPU, 2GB of RAM

What do these changes mean? In short, the iPhone 6S CPU and GPU are 70% and 90% faster respectively than the iPhone 6, while the iPhone 7 has a 40% faster CPU and 50% faster GPU than the iPhone 6S. It’s a tremendous change in two generations. That said speed is relative to your needs and an iPhone 6S will still deliver top notch performance for the next few years.

Lastly, the iPhone 6S introduced a second generation Touch ID fingerprint sensor which is twice as fast and accurate as the iPhone 6, but it is unchanged in the iPhone 7.

Camera Quality:

But what if you’re committed to Apple’s ecosystem? Looking at the specifications alone, a lot has changed:

  • iPhone 6 – Rear: 8-megapixel sensor, f2.4 aperture, Focus Pixels, EIS, dual-LED flash, 4K video recording. Front: 1.2MP Front Camera, f2.4 aperture, 720p video recording
  • iPhone 6S – Rear: 12-megapixel sensor, f2.2 aperture, Focus Pixels, Software Image Stabilisation, dual-LED flash, 4K video recording. Front: 5MP Front Camera, f2.2 aperture, 720p video recording
  • iPhone 7 – Rear: 12-megapixel sensor, f/1.8 aperture, Focus Pixels, Optical Image Stabilisation, quad-LED (dual tone) flash, 4K video recording. Front: 7MP sensor, f/2.2 aperture, 1080p recording

Elsewhere the iPhone 7 also adds ‘Raise to Wake’ (pick up the phone to preview notifications), which isn’t available on the other two models while ‘Tap to View’ (double tap the screen for the same effect) is coming but set to be an iPhone 8 exclusive.

Battery Life: 

While the Plus models remain stamina kings, the 4.7-inch models fall way behind both them and iPhone rivals with minimal capacity changes:

  • iPhone 6 – 1810 mAh
  • iPhone 6S – 1715 mAh
  • iPhone 7 – 1960 mAh

Yes, the iPhone 6S actually took a step backwards so Apple could squeeze in the haptic vibration motor for 3D Touch and the iPhone 7 doesn’t improve much over the iPhone 6 despite removing the headphone jack as Apple used most of the space to enlarge the haptic motor so it also could power the fixed home button.

One still relatively unknown hack is you can speed up iPhone charge times by using an iPad charger, but Apple still provides a low power charger in the box. Even then there remains no comparison to the mature quick charging technologies in Android rivals which can deliver a 30% charge in 15 minutes. What about wireless charging? Again that’s off the list, though yet again the iPhone 8 offers hope.

Storage and Pricing:

Apple doubled storage for both the iPhone 7 and (retrospectively) the iPhone 6S:

  • iPhone 6 – 16GB, 64GB, 128GB (no longer available to buy new)
  • iPhone 6S – 32GB ($549) and 128GB ($649) – no 256GB option available
  • iPhone 7 – 32GB ($649), 128GB ($749) and 256GB ($849)


A quick glance between the iPhone 6, iPhone 6S and iPhone 7 would suggest Apple has been standing still for the last three generations, but there have been consistent improvements each year. Given their price differences, choosing between the iPhone 6S and iPhone 7 is more difficult than it should be but the iPhone 6 is a model that is now starting to show its age. Or you could hold onto your device until the release of the iPhone 8, which is meant to dramatically change the look of iPhones after the initial release 10 years ago.
