  • 3D Touch support is mostly Apple-centric (for now)

The iPhone 6s is a solid upgrade for older iPhone owners.

While Apple has a reputation for innovation, the reality is that it tends to iterate relatively sedately, with only a single new phone model each year since it began producing iPhone models. The iPhone 6s looks largely like 2014’s iPhone 6 visually, but there are some engaging aspects hidden underneath that familiar external shell.

Upsides: Why you’d want the iPhone 6s

  • Improved processor: Apple’s latest iteration of its ARM-based processors is the Apple A9, and it’s a powerful little creature. Here’s how it stacks up using the cross-platform Geekbench 3 processor test:
    HandsetGeekbench 3 Single Core (higher is better)Geekbench 3 Multi Core (higher is better)
    Samsung Galaxy S6 Edge+14924893
    Samsung Galaxy S6 Edge13244626
    Google Nexus 6P12514597
    Samsung Galaxy S613474569
    Apple iPhone 6S25404410
    Apple iPhone 6S Plus24914391
    Google Nexus 5X11883198

    It’s not just a numbers game, however. Apple only produces a few iOS devices, and it maintains a stranglehold over both the hardware and software that goes into every iOS device. The end result of that is that it can very heavily optimise its software for the processors it chooses, which means that the iPhone 6s is capable of very good performance indeed. Because apps are still written with older iPhone models in mind, there’s also some future proofing here, as the iPhone 6s should still be able to run new apps a few years from now.

  • 3D Touch gives new interactions: The landmark "new" feature for the iPhone 6s is 3D Touch. Just as with the Apple Watch and its Force Touch feature, 3D Touch allows you to use a firm press to access secondary options. It’s the equivalent of having a right click on your smartphone screen for fast access to common options, although it’s far from universal across iOS apps.
  • Live photos: The other big new feature Apple touts for the iPhone 6s and larger iPhone 6s Plus is the live photos feature. It’s rather like the living images in Harry Potter, in that it captures a few seconds of video around when you take a photo. A 3D Touch press activates the photo, bringing it to life. As a party trick, it’s quite neat.

The iPhone 6s is available in a range of colours, including the new "rose gold" option.

Downsides: Why you might not want the iPhone 6s

  • Battery life isn’t great: The concept of iPhones not having great battery life is something of a running joke, and sadly this year’s iteration doesn’t do much to change that perception. In Geekbench 3’s battery test, with the screen dimmed, this is how the iPhone 6s stacked up:
    HandsetGeekbench 3 Battery Test DurationGeekbench 3 Battery Score
    Samsung Galaxy S6 Edge+8:24:105041
    Apple iPhone 6S Plus7:48:104681
    Samsung Galaxy S66:51:304115
    Google Nexus 5X7:14:204062
    Google Nexus 6P6:39:203754
    Apple iPhone 6s3:52:102321

    The one upside here is that one of iOS 9’s key features is low power mode, which dials down processor performance in order to eke out more battery life. It’s a good feature, but it’s also available on the older iPhone 6/6 Plus as well. Still, amongst the premium handset crowd, the iPhone 6s is the poorest battery performer.

  • Screen technology hasn't improved: We're seeing bigger, brighter, higher resolution displays from other manufacturers, but Apple's sticking with its "retina" screens for its devices. A few years ago they were top of the resolution tree, but they're now looking less impressive in the competitive premium smartphone arena.
  • 3D Touch support is mostly Apple-centric (for now): As with any new iOS feature, it’s up to app developers to implement 3D Touch. So far, support is sketchy, which means it’s a feature that you’re more likely to use only on Apple’s own in-house apps.

Who is it best suited for? What are my other options?

The iPhone 6s is an excellent upgrade option for existing iPhone owners if you’re using an iPhone 5s or older, because the generational gap between older handsets means that you’ll see a significant raise in performance, as well as the benefits of the larger display screen. It’s less compelling if you purchased last year’s iPhone 6 or 6 Plus, however.

iOS is exclusively Apple-controlled, so there are no other iOS devices from other manufacturers to compare it to. You can still buy the older iPhone 5s model from Apple, but only in a 16GB configuration and at a discount that isn’t that impressive when purchasing outright relative to the iPhone 6s.

Apple’s pricing policy for iPhones always sees them in a premium space, however, so if it’s just a question of finances, you’ve got the whole wide premium smartphone space to pick from. If style matters, consider the Samsung Galaxy S6 Edge +. If you’d like a waterproof 4K phone, the Sony Xperia Z5 Premium may be a better fit. If you'd like an Android phone that, like iPhones, always gets the latest software updates, consider the Google Nexus 6P.
