Review: Apple’s iPhone 6s + iPhone 6s Plus are nice but definitely not mandatory upgrades [Video]


This year’s iPhone launch week is over, so the earliest 13 million or so adopters are already playing with and forming opinions on the new iPhone 6s and 6s Plus. Past history suggests that Apple will sell over 100 million of these phones over the next year or so, which means that there are a lot of people still deciding on which model to buy.

If you’re still on the fence about buying one of Apple’s latest and greatest smartphones, there are a few important things you need to know. On the surface, the iPhone 6s and 6s Plus look nearly identical to their predecessors, as we’ve come to expect with “s” models, but there’s a lot of new tech inside that makes these models different. Will any of the changes justify this purchase for you? Or will you be better off with last year’s (now cheaper) iPhone 6 or iPhone 6 Plus? Let’s find out…

If your plan was to strut around town hoping people would notice your shiny new iPhone 6s, that likely won’t be the case, since this year’s model looks just like its predecessor. There’s a small awkwardly placed “s” on the backside to remind you just in case, but if you really want people to know you’re rocking a new iPhone, your best bet is to pick up the new Rose Gold color option. If you don’t care for that new color, you can spice things up with a case or a skin to keep it minimal.

Like last year, there are two iPhone sizes available. You have the iPhone 6s with a 4.7-inch display, 1334 x 750 resolution and 326 ppi, and then there’s the iPhone 6s Plus with a 5.5-inch display, 1920 x 1080 resolution, and 401 ppi. Both displays are super crispy, but that’s especially true for the iPhone 6s Plus, though you’re dealing with a much larger phone at that point.

If you’re hoping for big changes, this isn’t the year for them. The iPhone 6s and 6s Plus story is really about a collection of small details and a few stand out features.

Check out our iPhone 6s and 6s Plus review video below:


Let’s start with performance — these new iPhones are crazy fast. Inside you’ll find Apple’s latest A9 processor and 2GB of RAM, which may sound like less than some other phones, but Apple’s RAM management is absolutely phenomenal. Benchmarks show very promising results and overall, performance alone may be enough incentive to upgrade if speed is what you desire. Everything is very smooth and apps run like a champ with the new processor. That said, last year’s iPhone 6 is still a fast phone, and happens to be cheaper now.

As for size, the iPhone 6s Plus is much better when it comes to playing games, watching videos, browsing the web, and pretty much anything else you’d expect out of a larger screen. Personally, I prefer the smaller form factor of the iPhone 6s, even if the battery life and resolution take hits by comparison.

3D Touch

While the screens on these new iPhones are the same as last year’s, the touch technology behind them is much different. This year Apple has introduced a new 3D Touch feature that will actually detect the amount of pressure applied to the screen with your finger, and trigger various actions. With 3D Touch, you can tap on the display for standard actions, but you can press into the display for more features. Think of this as three options: a tap, a soft press, and a hard press, all of which can do different things depending on the pressure applied and where the action is taking place. Recently, we put together a video rundown of the best 3D Touch features available and if you’d like to check that out, you can find it embedded below.

Not everything with 3D Touch is amazing at the moment, but I do have some favorites. For example, you can get quick access to app-specific features with a hard press on the icon, which I enjoy using with a select few apps — not many third-party apps are compatible yet, but more are rolling out each day. You also have the ability to 3D Touch the keyboard when typing. With a soft press, you can use the keyboard as a trackpad to move the cursor around the screen, and with a hard press you can easily select text from a line.

Another one of my favorite features is quickly previewing links and other items. The same rules apply here: 3D Touch on a link to open a small preview window, then you can press even harder to pop it open into full browser mode. Apple calls this Peek and Pop, and it’s quite useful in some situations. It can also be used in places like the Photos app, Calendar, Messages, Notes, basically anywhere that there’s a list style view of items.

In most cases, it’s not incredibly faster to use this feature, but it’s handy nonetheless. 3D Touch has potential for sure, but don’t let 3D Touch be the main reason you upgrade — at the moment, without mainstream app support and innovative uses, it’s not worth the hype. This will happen in time, but trust me when I say that it’s not here yet.


Well, if 3D Touch isn’t worth the upgrade, certainly the camera must be, right? The iPhone 6s and 6s Plus both feature an all new 12-megapixel still camera this time around, which also shoots up to 4K video, but you’ll only get optical image stabilization on the iPhone 6s Plus. Luckily, the iPhone 6s does utilize digital stabilization with 4K video to keep everything smooth, but it won’t work like OIS does for low light photos. The new camera also shoots higher resolution Slo-Mo video at 120 frames per second in 1080p, which is great but not a huge selling point. Photos are natural-looking and can definitely look good, especially if you’re willing to do a little editing work. Apple’s photos aren’t as sharpened or saturated as other smartphone cameras on the market, for better and for worse.

Check out our 4K video test below:

Here’s the problem: this is probably the first year where Apple’s upgraded camera didn’t whip the pants off its Android competitors. Apple’s new sensor is great, and the photos are totally nice, but in direct comparisons, they fall short of rivals such as Samsung’s Note 5 and Galaxy S6. Why? Apple’s photos are now flatter in color, so you’ll need to edit them to make them look as good as the pictures Samsung’s cameras snap without processing. You can see the differences yourself in my Galaxy S6 and Note 5 reviews. Don’t get me wrong, iPhone 6s photos and video are super crispy, but if I had to choose just one camera to bring with me, the 12-megapixel iPhone 6s camera wouldn’t beat out its top competitors in overall quality.

Check out our iPhone 6s/6s Plus camera gallery below:

On both of the devices, there’s a 5-megapixel camera above the display with 720p video recording capabilities and a flash, but it’s probably not the kind of flash you’re thinking about. Apple calls this feature Retina Flash. According to Apple, there’s a special display chip inside that helps detect the ambient light around you, then matches the tone with a flash of the display that’s three times brighter than usual. I probably won’t use it much, but it’s pretty handy when you need it.

Touch ID & Live Photos

Speaking of camera features, Apple has a new Live Photos feature which is pretty neat, but not something I’ll use often. It will allow you to take a normal photo, which can then be brought to life (with audio and 3 seconds of surrounding low-res, low-frame-rate video) by using 3D Touch. You can share these Live Photos and even set them as wallpapers, though you’ll have to 3D Touch on the lock screen to see any movement from them. It’s a cool feature for some people, just not for me really.

Touch ID improvements are also a big part of the iPhone 6s and 6s Plus. It’s actually twice as fast over last year’s model and you can really tell the difference. Gone are the days of quickly pressing the Home button to view your notifications — it’s that fast. If I just want to check my notifications now, it’s much easier to use my knuckle to press the Home button, or simply use the Sleep/Wake button on the side of the phone. Once again, the Touch ID improvements aren’t really a reason to buy the iPhone 6s or 6s Plus, but they’re nice.

Battery Life

If all of the reasons mentioned in the video aren’t good enough to warrant buying the new iPhone, surely battery life has improved this time around, right? Nope. It’s actually about the same as last year’s, which is cool if you think about all the extra tech packed inside, but there’s no revolutionary break-through on battery performance here. I struggle to get a full day from the iPhone 6s, while the 6s Plus definitely can last a day and then some. That would be great run time, but I’m just not a fan of how large the Plus model is. It’s not right for me.

The Verdict

So we’ve basically covered everything that would make the iPhone 6s and 6s Plus a worthy purchase or upgrade over its predecessor, but somehow, it doesn’t add up to enough in my book. 3D Touch is cool, the camera has been bumped up, and you definitely won’t find a pink iPhone anywhere else, but none of these reasons scream “must upgrade” to me. I’ve heard it said elsewhere that the iPhone 6s and 6s Plus might be worth buying because all of their small improvements collectively make for a large year-over-year change. But after testing both phones, I’d say that the small improvements start out exciting but quickly begin to feel underwhelming. This isn’t a case of many small things adding up to one big thing, but rather, many small things feeling small.

Should you buy the iPhone 6s or 6s Plus? If you have an iPhone 6 or 6 Plus, I’d recommend sticking with it. But if you have an older iPhone or another device you’re considering upgrading, you could comfortably go with whichever iPhone 6 or 6s model appeals to you, or wait another year for the iPhone 7. Whether you go with a cheaper iPhone 6 or hold out for the iPhone 7, you won’t be missing out on much by skipping the 6s.

If you’re not familiar with my past work, I have over 1,000 review videos online, and have tested nearly every flagship smartphone across the iOS and Android ecosystems. I currently have all of this year’s flagships in my personal possession, which lets me do direct comparisons between the performance of iPhones and their rivals. For this review, I purchased iPhone 6s and iPhone 6s Plus units with my own cash for testing, so I know what it’s like to spend money on phones and need to decide whether to keep them or sell them. My feeling is that unless you’re rocking a 5s or anything lower, I’d save my money and wait. If you don’t currently have an iPhone, these are pretty nice, but so are last year’s models and they’re cheaper now, too. Don’t get me wrong, I’m all for improvements and these new devices are very fast. But unless you’re easily satisfied with incremental upgrades, the iPhone 6s and 6s Plus won’t deliver the “huge” smartphone upgrade you may have been waiting for.

    Ok, the first time I am thinking about not waiting for my 2 year upgrade but instead getting a new iPhone the very next year you tell me not to do so, as it’s not ‘all that mandatory’. This makes me rethink my initial response, so a BIG thanks to you Dom for this article.

    • dcj001 - 7 years ago

      I paid $749 for a new 64 GB iPhone 6 last year, and I am happy that I paid the same amount this year for an upgraded 64 GB iPhone 6s.

      It is significantly faster, and the new features definitely make a big difference!

  2. rogifan - 7 years ago

    So what would constitute a non-incremental update? Aren’t all smart phones at this point incremental upgrades? Plus how many people are buying new phones every year? For someone coming from a 4S, 5 or 5S/C this certainly would be more than an incremental upgrade.

    • ag80911 - 7 years ago

      What a weird article – besides housing, health and food – there is nothing mandatory. Let me tell you a secret – unless you are hoping for 4GB RAM, 2GhZ CPU and 20MP camera – next year upgrade will pale in comparison – unless a new casing is the big upgrade Dom is waiting for.

  3. o0smoothies0o - 7 years ago

    ‘Not mandatory’. Hahah seriously? No purchase will ever be ‘mandatory’ dear god writers need to choose more appropriate words. I hate when people say ‘but do you NEED it?’ like has been said about the watch, um, no, you don’t need it, just like you don’t need anything besides food, water, and shelter. Turns out humans did well before smartphones, before computers, before vehicles. Technology makes the world better (also horrifically bad) and easier, but it certainly isn’t needed.

    The fact about these phones is, they’re the biggest upgrade to an S model so far. If people like the features, buy it. If you’re someone that likes increased resolution and display quality more, along with thinner bezels, maybe wait until the iPhone 7. Alternatively, upgrade yearly like a champ.

  4. Soooo – what constitutes a viable feature for an upgrade? The phone has to look different or offer a different screen size? Also, you forgot some things (unless I missed them) such as ‘Hey Siri’ listening all the time now thanks to the integrated co-processor and the rapid fingerprint recognition.

  5. no tech is mandatory. I could easily survive with an old nokia that could only SMS and call. Its all about what you want to spend your money on and how much money you have to spend. If the price on these phones doesnt impact your life much at all, and you like new tech toys, theres really no good reason not to buy it. If it hurts your wallet and you have an iPhone 6 all ready, then its probably a stupid investment. Simple as that.

  6. For the review, thank you. I think that if the article was written from a non-biased POV, it would be far more helpful. It started from the premise that it was not worth the upgrade and never really deviated from that. That’s okay from Endgaget or Business Insider (well, a requirement from them, really) but 9to5mac should really either be pro upgrade or at least not con upgrade. And I’ve never not been happy with an S upgrade. Some people aren’t, but if one is reading this site, then most likely they are, too.

  7. yojimbo007 - 7 years ago

    I dont agree.. First off there is no such thing as mandatory upgrade!
    That said iphone 6s It a very significant upgrade.. Even for iphone 6 owners..( speed, speed , speed ,, awesome camera, and 3d touch )
    For anyone coming from an iphone 5s and older models .. It will be a mind blowing upgrade!

  8. mpias3785 - 7 years ago

    If you have a 5s or older, It’ll blow your mind! In Geekbench results, the 6s single core score is faster than the 5s multi core. 3D touch will become more useful as more apps adapt, but just having it turn the keyboard into a trackpad makes editing text so much easier that I’m finally going to shut up about the lack of arrow keys, and that constitutes a miracle!

  9. rahhbriley - 7 years ago

    I’m frankly baffled by this article.

  10. richardshears - 7 years ago

    I went for the iPhone 6s Plus. The bad points are that battery life is not quite as good as my previous 6Plus, at the end of the day I used to have between 80% to 88% depending on usage (I uninstalled fracebook and messenger). Sadly that’s now down to 69% to 76%. The camera is good but not much better for photos and not worth upgrading just for that. 4K video is for me a killer feature (and the main reason for my choosing to upgrade), not everyone will get as much mileage out of this feature but image stabilisation for video is helpful for me. The videos I produce are 1080p but where having the 4K feature is a real boon is being able to crop into the frame during edit and pan across the stage without the loss in resolution. Whist not as good as actually being behind the camera and panning and zooming to follow the subjects, as I have to be behind the sound desk I can’t.
    The other being plus point is the extra RAM really speeds up multi tasking and web browsing across multiple tabs. Also apps have not crashed out which I attribute to increased headroom.

    Now the downside that I’ve experienced. Graphic glitches e.g. Misplaced text or dialogues, orientation glitches such as in portrait, opening an app like safari opens landscape – fixed by twitching the phone to landscape then back to portrait , then going back to home screen to the same, also happens on occasion when app switching.
    Also have problems such as losing connection to cellular with only a reboot fixing it. Also wifi dropping out and not reconnecting without turning off wifi and then back on.

    Live photo – meh, not my thing I guess, reminds me of gif.
    3D Touch- could be great but too early to tell. Love using it in mail, but not a lot else makes use of it yet in any meaningful way.

    Hope this helps those that are thinking of upgrading in some small way.

  11. migsimoes (@migsimoes) - 7 years ago

    being mandatory or not it is a individual decision on every case. of course, since the beginning, every step, every year comes something new, the question is, is the new things useful for you? the other question is, what is your actual phone version?
    for makes sense every other year do the upgrade, and this time i did it again, from 5s to 6s there is a big difference, and has been so every 2 years

  12. Makarand Phatak - 7 years ago

    What a stupid article, must have used better words than “Mandatory Upgrade” lol
    Any way I can see huge difference if I compare iPhone6s and iPhone6..– again personal opinion ..

  13. joshdoremus - 7 years ago

    Such a negative review. Maybe should have been posted on 9to5google?

    • sally (@FedGoat) - 7 years ago

      wow, so someone tells the truth and it’s negative? The photo’s aren’t much better. 3rd touch, not that great. The Note 5 camera still owns the iphone.
      People are all hung up on the title. Of course no upgrade is mandatory. any idiot knows that. He wasn’t trying to insinuate that ANY upgrade was mandatory.

      Apple heads get all bent out of shape when their new shiny doesn’t get reviewed as THE BEST UPGRADE EVER!

      I work for apple and have the iPhone 6. I see absolutely NO reason to ditch my 6 for an S… I will say, the S is stupid fast. but the regular 6 isn’t slow by any means. My Note 5 ( yes, I have both phones) is my go to for pictures. The gif picture thing isn’t new, HTC and Nokia both did it years ago.
      It’s basically a useless feature because to animate you have to have your big thumb pressing down blocking 1/4th of the picture.

      After taking many pictures with the S, i’m actually very disappointed in the camera. After having the Note 5, I expected the new iphone camera to match it and even best it. Nope. Not even close. Smoked by samsung.

      I love apple, but I don’t hate android or windows or any other company because I am a blind sheep. Fact is, the new S is a very Minor update overall.

      Apple still refuses to do widgets ( lock screen widgets are stupid and useless, and don’t count as a widget at all), still can’t change a native app, even when a 3rd party app is 10x better than the stock one. Swipe on the iPhone was the worst implementation ever and useless. Still can’t arrange icons how I want them thanks to the dumbest feature ever, auto arrange…

      it’s ok to love apple. I love a lot about apple, but I am going to call them out where they need to be called out. I don’t think apples doodoo doesn’t stink.
      I am not a blind fanboy that whatever apple tells me is good, really is good. It’s not. Apple needs to stop with the gimmicks and allow more user choices.

  14. charismatron - 7 years ago

    Very reasonable article.
    It’s a nice incremental upgrade, but without any new killer features that should compel anyone to upgrade from a 6.

    This article fulfils its role answering the question whether the iPhone 6S is worth the investment, or anything to get terribly excited about.

    As for “needing” an upgrade, obviously no one *needs* one (for survival), but in the context of a tech blog–which many have chosen to overlook is what this site is–it makes perfect sense to grade a phone in terms of features that are immediately exciting, useful, and absolutely necessary (need it or don’t need it). The conclusion that the iPhone 6S is not one of these kinds of phones is good to know.

  15. Drew (@gettysburg11s) - 7 years ago

    Its interesting, this article. It seems to say that the ‘S’ upgrade isn’t a big deal. However, every S upgrade has been big, if you look back. For this one, Apple changed literally everything, and most agree its a worthy upgrade. Is it mandatory? Well, having a smartphone at all is not mandatory. I say, if you can afford the upgrade, go ahead, you won’t regret it.

  16. ny3ranger - 7 years ago

    There is no upgrade in the world that is “mandatory”. You could have no cell phone and it still wouldn’t be “mandatory”. If you have the money to upgrade then do if not then don’t.

  17. It’s weird to me that you’re panning the camera for producing realistic color reproduction of the real world instead of fake and oversaturated colors like Samsung cameras and screens do.

  18. just1n12 - 7 years ago

    Not manditory unless you have a 5S or older :p

  19. Igor Magnani - 7 years ago

    Iphone 6 was the one that wasn’t mandatory. Such little difference from the 5S, just screen size, which in my case I like to keep my phone small, and design. Same RAM, shy processor upgrade, camera upgrade also fell short. Little config bump and design, that was basically it.
    Oh, not to be unfair, NFC/ApplePay was the key factor for me. That was great. But since I live in Brazil and I don’t think I’ll be using ApplePay any time soon, I didn’t even consider upgrading. I’m happy with my 5S, but I think 3D Touch and 2Gb RAM would fit better my daily needs.
