What are all the differences between the iPhone 6/iPhone 6 Plus và iPhone 6s/iPhone 6s Plus? How much better are the newer models than their predecessors?
Please chú ý that the iPhone 6, iPhone 6 Plus, iPhone 6s, và iPhone 6s Plus all have been discontinued. However, this Q&A has been updated with the latest iOS support details and more & is quite useful for anyone buying or selling one of these models on the used market.
With even a fairly detailed look at an iPhone 6 or iPhone 6 Plus và a newer iPhone 6s or iPhone 6s Plus side-by-side it would be easy to lớn mistake them for one another, as the general designs practically look identical, although the small "S" on the backside of the iPhone 6s models (and the lack of FCC iconography) is a dead giveaway.
There actually are four iPhone 6 models, four iPhone 6 Plus models, three iPhone 6s models, và three iPhone 6s Plus models, but this Q&A mostly covers collective differences for relative simplicity.
External Differences
At the time of introduction, the iPhone 6 & iPhone 6 Plus were available in black & space gray, white and silver, or white and gold, but táo discontinued the gold color option on September 9, 2015 upon introducing the iPhone 6s và iPhone 6s Plus (but re-introduced it in đài loan trung quốc and Taiwan with a 32 GB variant in February và March 2017 only to lớn discontinue the mã sản phẩm entirely again in September 2018). The final models were offered in black và space gray, white and silver, và white and gold, as well as a new white and pink-tinted "Rose Gold" option (pictured above).
The overall kiến thiết of both lines is quite similar -- with aluminum cases dominated by the display & softly rounded sides -- but the iPhone 6s and iPhone 6s Plus have a slightly less slippery finish, are slightly thicker and heavier, & made from aerospace-grade 7000 series aluminum, which is much less likely to lớn bend than the aluminum used by its predecessors. The iPhone 6s and iPhone 6s Plus also have a new rubber gasket around the display to lớn reduce the risk of internal water damage.
Although the specific parts are different, the "Retina HD" display in the smaller iPhone 6 và iPhone 6s devices both are are 4.7" (1334x750) with a 1400:1 contrast ratio, and 326 ppi px density and the the larger iPhone 6 Plus and iPhone 6s Plus devices are 5.4" (1920x1080) with a 1300:1 contrast ratio and 401 ppi pixel density.
However, the iPhone 6s & iPhone 6s Plus displays are covered by an ion-strengthened glass cover that táo bị cắn boasts is the "strongest glass on any smartphone." Furthermore, these displays incorporate new pressure-sensitive "3D Touch" capability with tư vấn for gestures that hãng apple refers to lớn as "Peek and Pop" to "dip in and out of content without losing your place" for quicker access to lớn a variety of functions within the iOS & third-party software.
The iPhone 6s và iPhone 6s Plus also have an advanced "Tapic Engine" in lieu of a simpler vibration sensor and a faster "second generation" cảm ứng ID fingerprint sensor in the home button for biometric authentication. Both lines have a bottom mounted headphone jack, microphone, Lightning connector, và a single speaker. Each ships, or shipped, with "EarPod" headphones that include the integrated Remote và Mic, as well.
Camera Differences
The iPhone 6s & iPhone 6s Plus have much more advanced cameras than their predecessors. The front cameras have a "FaceTime HD" camera with a 5 megapixel sensor compared to lớn a 1.2 megapixel camera on the iPhone 6 & iPhone 6 Plus.
The rear-mounted "iSight" cameras have even more significant differences:
| 6 | 6 Plus | 6s | 6s Plus | |
| Megapixels: | 8 MP | 8 MP | 12 MP | 12 MP |
| Aperture: | f/2.2 | f/2.2 | f/2.2 | f/2.2 |
| Pixel Size: | 1.5µm | 1.5µm | 1.22µm | 1.22µm |
| LED Flash: | Dual | Dual | Dual | Dual |
| 4K Video: | No | No | 30 fps | 30 fps |
| 1080p Video: | 30/60 fps | 30/60 fps | 30/60 fps | 30/60 fps |
| Automatic Image Stabilization: | Yes | Yes | Yes | Yes |
| Optical Image Stabilization (Photos): | No | Yes | No | Yes |
| Optical Image Stabilization (Video): | No | No | No | Yes |
Although some independent tests concluded that the camera difference between the iPhone 6s and iPhone 6s Plus and their predecessors aren"t as dramatic as the specs might indicate, more detailed tests vị show a significant difference as well as steadily improving camera quality for the iPhone year after year.
Identification Differences
It is easy to differentiate between the iPhone 6, iPhone 6 Plus, iPhone 6s, & iPhone 6s Plus when they"re side-by-side based on dimensions and the presence or absence of an "S" on the back, but identifying the specific device requires more precise data.
Many of the devices can be identified by mã sản phẩm Number, which is listed on the back of each phone in tiny type, but not all can be individually identified in this way, either.

So, should I buy an iPhone 6/iPhone 6 Plus or an iPhone 6s/iPhone 6s Plus? Which is best for me?
For most users, a newer iPhone 7 or iPhone 7 Plus, iPhone 8 or iPhone 8 Plus, or even newer iPhone would be a better choice.
However, for those on a very tight budget, and only compared to one another, you should buy a newer iPhone 6s or iPhone 6s Plus mã sản phẩm as they"re essentially designed as an improvement of the earlier models (unlike the iPhone 7/iPhone 7 Plus và later models, they have headphone jacks, as well, which may be of interest lớn those with older, expensive headphones in particular).
The iPhone 6s & iPhone 6s Plus provide (1) a stronger và more water resistant case, (2) stronger displays with more advanced capability, (4) a faster touch ID sensor, (3) better cameras with 4K đoạn clip support, (4) faster performance, (5) twice the RAM, (6) more advanced connectivity, & (7) current tiện ích ios support. That"s a great khuyến mãi of improvement for the price difference.
The iPhone 6 & iPhone 6 Plus still are capable, and can be worth considering for those on the tightest of budgets, but because they no longer support the current version of the iOS, app support will continue to lớn wane from here.
