With so many similarities, many people may wonder exactly what makes the iPhone 6S and iPhone 6S Plus different? Truth is, they're not that different. In fact, almost every major element of the phones is the same.

But there are a few differences—some subtle, some very obvious—that set the two models apart. If you're trying to decide which one is best for you, read on to discover the 5 subtle things that make them different.

The first and least subtle difference between the models is their screens:

  • Physical size—The iPhone 6S has a 4.7-inch screen, while the iPhone 6S Plus has a 5.5-inch screen (this is the same set of screen sizes as on the 6 and 7 series models that preceded and succeeded them) 
  • Resolution—Along with the difference in the screens' physical size, they have different resolutions, too: 1334 x 750 pixels for the 6S and 1920 x 1080 for the 6S Plus.

A bigger screen may seem appealing, but the 6S Plus is a very large device (more on that in a minute). If you're considering the two iPhone 6S series models, but aren't sure which is right for you, make sure to see them in person. You should know pretty fast whether the 6S Plus will be too big for your pockets and hands.

If you just compare the specs of the cameras on the two models, they'll seem identical. And they are, except for one crucial difference:  The 6S Plus offers optical image stabilization. 

The quality of the photos and videos we take is affected by shaking of the camera—either from our hands, because we're riding in a car when taking the photo, or other environmental factors. The image stabilization feature is designed to reduce that shaking and deliver better photos.

The 6S achieves its image stabilization through software. That's good, but not as good as image stabilization delivered by hardware built into the camera itself. It's this—also called optical image stabilization—that makes the 6S Plus different.

The everyday photographer may not find much difference in the photos from the two phones, but if you take a lot of photos or do it semi-professionally or professionally, the 6S's optical image stabilization will matter a lot to you.

Size and Weight

Given the difference in screen sizes, it should come as no surprise that the iPhone 6S and 6S Plus also differ in their size and weight.

  • The iPhone 6S measures 5.04 inches wide x 2.64 tall x 0.28 deep
  • The iPhone 6S Plus is 6.23 inches wide x 3.07 tall x 0.29 deep

The difference in size is driven almost entirely by the screen sizes of the two models. Those differences also affect the weight of the phones.

  • The iPhone 6S weighs 5.04 ounces
  • The iPhone 6S Plus weighs 6.77 ounces

The weight probably won't be too much of a factor for most people—after all, 1.73 ounces is fairly light—but the physical size of the phones is a big difference for holding in your hand and carrying in a purse or pocket.

Battery Life

Battery life

Because the iPhone 6S Plus is taller and a little bit thicker than its smaller sibling, it's got more room inside. Apple takes great advantage of that room by giving the 6S Plus a bigger battery that delivers longer battery life. Battery life for the two models breaks down this way:

iPhone 6S
14 hours talk time
10 hours Internet use (Wi-Fi)/11 hours 4G LTE
11 hours video
50 hours audio
10 days standby

iPhone 6S Plus
24 hours talk time
12 hours Internet use (Wi-Fi)/12 hours 4G LTE
14 hours video
80 hours audio
16 days standby

Needless to say, the extra battery will keep you from having to recharge as often, but the 6S Plus's bigger screen also consumes more power.

The last, and perhaps most important, difference between the iPhone 6S and 6S Plus is price. To get the bigger screen and battery, and better camera, you'll pay a bit more. 

Just like with the iPhone 6 and 7 series, the 6S series differs by US$100 per model. Here's the breakdown of the prices for the 6S models:

  • iPhone 6S - 32GB: $549
  • iPhone 6S Plus - 32GB: $649


  • iPhone 6S - 128GB: $649
  • iPhone 6S Plus - 128GB: $749
