Conclusion & End Remarks

While the iPhone XS and XS Max in one sense are just another iteration on last year’s iPhone X, they’re also a big shift for Apple’s line-up. Rather than being actual successors to the iPhone 8 and 8 Plus they're closer to next-generation replacements, but with some significant differences. In that respect I do regret missing out on the iPhone XR for this review, as I think it’s going to be an incredibly attractive alternative to the XS models.

Design wise, there’s not much to talk about the XS: the smaller variant is nigh identical to the iPhone X, with the only visual differences between the phones being the added antenna lines on the XS, virtue of the new 4x4 MIMO cellular capabilities of the phones.

The XS Max sports Apple’s biggest screen, and in a sense I do like the design more because it does have a bigger screen-to-body ratio. Apple’s bezel design is intentional, but I did hope they had shaved 1-2mm off the sides, as I’ve gotten used to other, more full-screen devices. One thing to consider about the XS Max, is that’s it’s really heavy for a phone, passing the 200g mark at 208g.

The screens of the XS and XS Max are the best displays among any devices on the market: While Samsung still has a density advantage, the Apple phones just outgun competing phones in terms of colour accuracy and picture quality. The 10-bit panel allows seamless colour management between sRGB and Display P3 modes depending on content, and Apple’s still the only vendor able to do this without having significant drawbacks.

The Apple A12 is a beast of a SoC. While the A11 already bested the competition in terms of performance and power efficiency, the A12 doubles down on it in this regard, thanks to Apple’s world-class design teams which were able to squeeze out even more out of their CPU microarchitectures. The Vortex CPU’s memory subsystem saw an enormous boost, which grants the A12 a significant performance boost in a lot of workloads. Apple’s marketing department was really underselling the improvements here by just quoting 15% - a lot of workloads will be seeing performance improvements I estimate to be around 40%, with even greater improvements in some corner-cases. Apple’s CPU have gotten so performant now, that we’re just margins off the best desktop CPUs; it will be interesting to see how the coming years evolve, and what this means for Apple’s non-mobile products.

On the GPU side, Apple’s measured performance gains are also within the promised figures, and even above that when it comes to sustained performance. The new GPU looks like an iteration on last year’s design, but an added fourth core as well as the important introduction of GPU memory compression are able to increase the performance to new levels. The negative thing here is I do think Apple’s throttling mechanism needs to be revised – and by that I mean not that it shouldn’t throttle less, but that it might be better if it throttled more or even outright capped the upper end of the performance curve, as it’s extremely power hungry and does heat up the phone a lot in the initial minutes of a gaming session.

On the camera side, Apple made some very solid improvement all-around. The new sensor’s increased pixel size allows for 50% more light sensitivity, but the improved DTI of the sensor also allows for significantly finer details in bright conditions, essentially increasing the effective spatial resolution of the camera. SmartHDR works as promised, and it’s able to produce images with improved dynamic range. The telephoto lens is the one use-case where the XS really stands out over the iPhone X as exposure and colour rendition are significantly improved, one of the weak points of many telephoto cameras nowadays. Overall in daylight, the new iPhone is easily among the best smartphone cameras on the market.

In low light the iPhone XS also sees a big improvement, however it’s not enough to quite match Samsung’s hardware and Huawei’s processing. I do hope Apple will make use of the newfangled computational photography in more use-cases, as we’re seeing some great innovation from the competition in this regard.

Video recording of the iPhone XS is also a major improvement of the phone. From better dynamic range, better stabilisation, to better and now stereo audio recording, Apple makes a significant leap in the video performance of the new iPhones.

In terms of battery life, it was surprising that the iPhone XS wasn’t much of an upgrade over the iPhone X in our test. I’m still not sure if this is something related to some sort of hidden inefficiency of the A12, or maybe something to do with the new WiFi or cellular modem. For the latter, we’ll be revisiting the topic shortly, and to also re-validate the battery life numbers of this review.

For the iPhone XS Max, I wasn’t surprised to see battery life be less than on the iPhone 8 Plus – the OLED screen is less efficient than the LCD display of last year’s phone – and the increased battery capacity is not enough to counter-act this. It’s just something to keep in mind for the big-phone users out there eyeing the iPhone XS Max in particular.

Overall, are the new iPhones worth it to upgrade to? If you’re an iPhone X user, I think my answer is no. If you’re coming from an older device, then my answer is… wait it out. When having a hands-on with the XR at the keynote event, my first thought was that this would be the model that would see the most success for Apple this generation. The problem here is that Apple is asking for a lot of money – if you’re entrenched in the iOS ecosystem, I think it’s best to evaluate the individual pros and upgrades that the new iPhone XS brings over your current device.

The value proposition aside, the new iPhone XS and XS Max are, as always, extremely polished devices, and the best phones that Apple has released to date.

    I wonder how A12 would do on Android or Windows... I'm not into Apple but they have done a fantastic job with their SoC Reply

    Probably nowhere as good as it is projected here.
    What is the bloody point of these supposedly super fast SOCs with massive caches and execution units when the OS running on it will be the highly limited, crippled and locked OS like the IOS. No emulators, no support for USB peripherals like gamepads, mice or keyboards, poor excuse for file management, no access to outside apps, no ability to run non webkit based browsers, no ability to seamlessly transfer data to and from windows desktops and multiple other limitations.

    All and well getting excited over this SOC but its like Having a 450 BHP ferrari running on a 80 mile speed limiter with an automatic transmission. All that power is useless and will remain unutilised.

    Until they allow other OS to run on their hardware, the comparisons are meaningless. I can do a hell lot more on a pithy 835 than I will ever be able to do on an A11 or A12.

    You are wrong and I know you are too narcissistic to realize that. I would pity you but your username tells me you don't deserve any pity. Reply

    Fantastic hardware (well, except the notch), shame it's only locked to one OS. Would love to see an Android phone with hardware like that. Reply

    Well Qualcomm is working on quite a few things, new SoC, NPU, and Samsung is totally redesigning their GPU, so...maybe sooner than later (S10) Reply

    It'll be interesting to see what comes of that effort - so much of the Android market is feature phone replacements - the actual percentage which represents high end flagship phones is pretty slim.

    If a bigger percentage of the Android market is willing to pay for silicon with that increased compute capacity, there may be hope.

    But will they? Microprosser Reports says that each new SoC from Apple cost, the year of introduction, between $34-38. Top Android SoCs cost between $24-28. That’s a big difference. These phones compete wither each other, and price while Apple mostly competes against itself. Reply

    The reason, or I should say, one of the reasons why other manufacturers are copying Apple’s notch, is because it allows a full screen phone. Notice that Samsung has edge to edge, but still retains a shorter screen on both the top and bottom. The notch removes 2-3% of the screen area, depending on screen size, which is very little. Now take the Galaxy 9+, and you’ll notice that when the entire top and bottom cutoffs are added together, it amounts to about 10% of the possible screen size.

    It’s why the new Pixel and others are moving to the notch. In the cases where the notch is just being copied, it’s ridiculous, because those companies are still using a chin on the bottom, and the notch is just there to copy the iPhone.

    No. They are copying the iphone for the look. If they were copying to maximize screen area they would copy Essential. Apple removed the chin and the notch is needed for face id - they have a good reason. Some copycats(not all) ape the look and keep the chin. A good compromise is the impending OnePlus T. It has teardrop notch and minimized chin that makes it look actually good. Asus is on the other side of the spectrum. They even bragged they wanted to copy the look of the iphone X. Reply
