Our Verdict

The 6s was a significant update compared to the iPhone 6, bringing 3 chiều Touch, a much better camera, Live Photos, more RAM và a much faster processor, but should you buy one? With five years having passed since the launch probably not, but it does still have some things going for it…

It’s been a few years since apple stopped selling the iPhone 6 & 6s, but you might be thinking about buying one of these handsets second hand, or perhaps a family thành viên is passing their old handset onto you. In that case you will want lớn know how the two phones compare, & perhaps whether buying an iPhone 6 or 6s is a good or bad idea, và if an iPhone 6 or 6s will be any better than the iPhone or other phone you have right now.

Alternatively you might not be sure whether the phone in your hand is the iPhone 6 or the iPhone 6s as the two look remarkably similar.

Whatever your reason to want khổng lồ know the difference between the iPhone 6 & iPhone 6s we are here to explain everything you need khổng lồ know.

What is the difference between the iPhone 6s và iPhone 6?

You might think that being an s-update there wouldn’t be a big difference between the two phones, but when táo introduced the iPhone 6s and 6s Plus in September năm ngoái there were some significant updates and changes including:

3D TouchBetter cameraLive PhotosFaster processorMore RAMNew aluminium (presumably khổng lồ combat bend-gate – a tendency for iPhone 6 Plus phones to lớn bend in the pocket!)

As for how khổng lồ tell the difference between the different devices, if you have one in your hand you could demo for 3d touch by pressing on an icon or two to see if the second level menu appears. Or you could open the camera and see if Live Photos is an option. But the most obvious way lớn tell is to look in Settings > General > About và find mã sản phẩm Name. If it’s not listed there then look for the model Number. You can tap on the model Number to reveal the code starting with an A.

A1549, A1586 or A1589: iPhone 6A1522, A1524 or A1593: iPhone 6 PlusA1633 or A1688: iPhone 6sA1634 or A1687: iPhone 6s Plus.

You should also find this A number listed on the back of the phone if it’s a 6 or 6s generation và an if it’s a 6s or 6s Plus.


At first glance, you might think that the iPhone 6 và iPhone 6s are the same phone, but actually there are a number of kiến thiết differences between the two handsets.

First of all the iPhone 6s introduced a new colour option called Rose Gold. Otherwise both handsets are available in Gold, Silver & Space Grey.

The iPhone 6s is also made out of a more durable Series 7000 aluminium. This is presumably to lớn prevent a repeat of the Bendgate debacle that happened when some iPhone 6 Plus owners found that their iPhones had bent after prolonged periods of time spent in their pocket. The problem was probably exaggerated with only a few very vocal customers affected, but it’s a problem none-the-less và certainly a good reason lớn consider the 6s Plus over the 6 Plus.

Aside from that, the design & build of the iPhone 6 & iPhone 6s is essentially the same. There is a tiny increase in height, width, depth và weight for the 6s, but you’re unlikely khổng lồ notice.

The dimensions are as follows:

iPhone 6

iPhone 6 Plus

iPhone 6s

iPhone 6s Plus


138.3 x 67.1 x 7.1 mm

158 x 77.8 x 7mm

138.1 x 67 x 6.9 mm

158.2 x 77.9 x 7.3 mm






Screen size





There is not a significant difference in the dimensions of the iPhone 6 compared khổng lồ the 6s, or the iPhone 6 Plus compared to the 6s Plus, but there is a significant difference between the standard và the Plus models, so if you are considering moving from a 4.7in screen to lớn a 5.5in screen it’s worth bearing in mind that there are pros and cons about the bigger screen. The bigger phone weighs more (obviously) và is a bit more awkward khổng lồ hold, especially if you have small hands, in which case you’ll probably find that you can’t reach the entire screen with a single thumb. But there is a real benefit lớn be had from the extended screen space. Once you go Plus you probably won’t go back.

iPhone 6 vs iPhone 6s comparison: Display

The iPhone 6 và 6s both have a 4.7in display with a resolution of 1334 x 750 at 326ppi (pixels per inch), while the iPhone 6 Plus & iPhone 6s Plus have 1920 x 1080 pixel displays at 401ppi.

The big difference is the inclusion of 3d touch on the 6s models. Touch 3d means that the display on the iPhone 6s can distinguish between a tap, a light press & a hard press, & that opens up a whole host of new navigation, interaction và gesture possibilities. There is haptic feedback (a gentle buzz) so you know you have trigged the hard press functions.

In terms of what cảm ứng 3 chiều actually does, here are a few examples. Hard press on an icon on your home screen & you’ll see more options. In the case of the Camera icon you’ll get shortcuts khổng lồ Take Sefie, Record Video, and so on. When the iPhone XR launched apple was able khổng lồ create the same ‘hard press’ effect without 3 chiều Touch.

The irony with cảm ứng 3 chiều is that as useful as it is many iPhone users don’t even realise that the feature is there.

You can find out more about 3d Touch & how it works here. Or take a look in this video:

Where the iPhone 6 has an 8Mp rear-facing camera, the iPhone 6s has a 12Mp rear-facing camera.

Video recording improved from 1080p in the iPhone 6 to lớn 4K video clip recording on the iPhone 6s. The iPhone 6s Plus also gained optical image stabilisation for video.

The front-facing camera also got some improvements. It can capture 5Mp photos rather than 1.2Mp, và the display became a front-facing flash to make selfies even better.

Some of the tech behind the camera was improved & the iPhone 6s gained some camera related software features. For example, Live Photos arrived with the 6s. With Live Photos turned on your phone takes short videos clips rather than still photos. You can get some fun effects & it’s a good way to get photos of kids who are moving all the time anyway. Later versions of the tiện ích ios software made it possible khổng lồ create GIFs from Live Photos. Live Photos can be fun so they are probably a good reason lớn get the 6s over the 6.

iPhone 6 vs iPhone 6s specs and hardware comparison


Inside the iPhone 6s is the A9 64-bit processor and M9 motion coprocessor. At the time táo bị cắn dở said the iPhone 6s’s processor was 70 percent faster và had 90 percent better graphics performance than the A8 and M8 chipset used in the iPhone 6.

Here’s how the benchmarks compared at the time the iPhone 6s launched:

Modern iPhones are considerably faster of course, but this does demonstrate that there was s significant difference between the 6 and 6s.

Another significant difference was the RAM. The iPhone 6s was the first iPhone to siêu thị with 2GB RAM. The iPhone 6 has just 1GB RAM. The extra RAM can make a big difference.

As for storage, táo apple stuck with the same 16GB, 64GB & 128GB models when the iPhone 6s launch 2015, but in năm nhâm thìn the company introduced a 32GB version of the iPhone 8s, khổng lồ replace the 16GB & 64GB options.

There has never been a big difference between the price of the lower capacity và the larger capacity models so we would always advise you to lớn spend a little more lớn get more storage (although now that we can also rely on iCloud for storage the on-phone storage matters less).

Another change khổng lồ the iPhone 8s was the arrival of the second-generation cảm ứng ID. This fingerprint sensor is faster and more accurate than touch ID on the iPhone 6.

Connectivity for the four handsets are the same – they all offer 4G LTE Advanced, 802.11ac WiFi, công nghệ bluetooth 4.2, và NFC.

Finally, battery life is estimated to lớn be the same on all these handsets at up lớn 10 hours of internet browsing or 11 hours of video playback. However, if you are buying second-hand you can expect the battery life to be less.

Note that there was a problem with the batteries in the iPhone 6 and 6s models with hãng apple criticised for slowing down older phones to prevent shutdowns and maximise battery life. There was a program in place whereby apple would replace the batteries but that is now finished (Apple ran a không tính tiền replacement program from năm 2016 to the end of 2017 và a paid for program until the end of 2018). Read more about thebattery problems here.

You can now tell if your iPhone is being slowed down due lớn battery degradation by checking the status in Settings > Battery > Battery Health.

Verdict: Should you get the iPhone 6 or 6s

Back in năm ngoái when the iPhone 8s launched it was a significant update, despite the fact that critics usually look upon s-updates as minor updates. The update bought some significant changes though, including 3 chiều Touch, a much better camera, Live Photos, more RAM và a much faster processor.

If you were deciding between the 6 and 6s right now then we would say go for the 6s (Plus or standard) as it’s a much better phone.

But before you buy, if you are thinking about updating lớn the 6s from the iPhone 6 or even the 5s, then we’d recommend that you find a way khổng lồ afford a newer phone. There are so many handsets that have launched since that you could consider, from the iPhone 7, 7s, 8, 8s, & the iPhone X & beyond. A lot has changed in the past five years.
