iPhone 6s vs iPhone 6s Plus: A Full Overview

  • Save


  • iPhone 6s – The iPhone 6s is designed to be the most portable option of the two. Available in a range of colors, the iPhone 6s looks very smart, even today, with its premium build materials, clean lines, and perfectly proportioned chassis.
  • iPhone 6s Plus – The iPhone 6s Plus is basically the same deal, just stretched out. The display is larger (5.5in versus 4.7in) and the handset has a much larger footprint, owning to its bezels and the fact it still runs Apple’s TouchID/Home button. Both the iPhone 6s and iPhone 6s Plus feature headphone jacks too.

Winner? Both the iPhone 6s and iPhone 6s Plus look identical, as they follow the same industrial design principles. The only difference in how they look and feel is to do with their sizes; the iPhone 6s Plus quite a bit bigger than the more portable iPhone 6s.

If you prefer smaller, more portable phones, then the iPhone 6s is going to be more to your liking. Want a larger, more expansive display for viewing media and apps on? Go with the iPhone 6s Plus, as it gives you way more screen to play with.


  • iPhone 6s – The iPhone 6s features a 4.7-inch display with a 1334×750-pixel resolution at 326 ppi. It’s a TFT LCD panel that has a resolution of 720p, which is very low by 2019 standards. It’s still functional, but it is not Full HD.
  • iPhone 6s Plus – The iPhone 6s Plus’ display is superior on the resolution front. Not only does it have more pixels, but it’s also got a higher pixel per inch (ppi) density at 401ppi versus the iPhone 6s’ 326ppi. That being said, the smaller iPhone 6s actually has a slightly better contrast ratio of 1400:1 compared to the iPhone 6s Plus’ 1300:1. That means the smaller iPhone’s display can display just a bit more difference between the brightest whites and the darkest blacks.

Winner? The iPhone 6s Plus has a larger, Full HD display, so if high definition visuals are important to you, it is the one to go for. It’s only 1080p, however, so it does still pale in comparison to Apple’s newer QHD-totting iPhones like the iPhone XS Max. For their age, however, Apple’s iPhone 6s and iPhone 6s Plus displays have held up remarkably well. I definitely prefer the iPhone 6s Plus’ screen though. For browsing, apps, and gaming it is much, much better.


  • iPhone 6s – The iPhone 6s run Apple’s dual-core A9 chipset alongside 2GB of RAM. Back in the day, this was the #1 CPU for performance on the market. Moving around apps and the iPhone’s settings was buttery smooth and there was no hint of lag. Apple manages to do more with less when compared to its Android-powered stablemates, and the iPhone 6s is no exception to this rule.
  • iPhone 6s Plus – The iPhone 6s Plus runs all the same internals as the iPhone 6s, so performance is more or less the same. These phones first launched way back in 2015, so they’re not exactly spring chickens. Having said that, Apple’s iOS is designed to still run on them, so users’ opting to buy an iPhone 6s/6s Plus in 2019 shouldn’t have too many problems with respect to performance.

Winner? Again, it’s impossible to say whether the iPhone 6s Plus is better than the iPhone 6s with respect to raw performance. Both phones run the same chipset and the same amount of RAM. From a purely academic standpoint, they’re essentially the same in this context, delivering smooth, reliable performance across the board. Where things get slightly different is to do with the cameras and battery life. In these instances, the iPhone 6s Plus is the superior phone.


  • iPhone 6s – The iPhone 6s runs a 12MP camera on the rear and a 5MP front-facing camera. Image quality is decent enough, but the smaller iPhone 6s does lack one key feature the iPhone 6s Plus has – optical image stabilization.
  • iPhone 6s Plus – The iPhone 6s Plus wins it here because it also has optical image stabilization. Optical image stabilization can make your pics look a lot better by using optical components of the lens to reduce vibrations and camera shake. It should also be noted that that same optical image stabilization found in the iPhone 6s Plus also works for video

Winner? This aspect of the comparison is fairly straight-forward: the iPhone 6s Plus has a much better camera than the iPhone 6s. Why? Simple: it has Optical Image Stabilization (both for still images and video). This results in better quality shots and a higher standard of quality when shooting video. Even in 2019, the iPhone 6s Plus’ camera is still pretty darn good.

Battery Life

  • iPhone 6s – The iPhone 6s’ battery performance is just above average for an iPhone, meaning you can eke out of full day’s use if you don’t ride it too hard. In my experience, with normal usage, the iPhone 6s can get to around 5 pm with about 65% left in the tank
  • iPhone 6s Plus – The iPhone 6s Plus has insane battery performance, easily one of the strongest in the mobile space. It carries a large (for Apple standards) 2750mAh battery that will provide all-day battery life, even with heavy usage.

Winner? Like the camera section, this is another easy victory for the iPhone 6s Plus. Its larger 2750mAh battery delivers significantly better performance than the iPhone 6s’. The iPhone 6s Plus can go ALL DAY with heavy usage, whereas the iPhone 6s will struggle to get past 3 pm if you’re using it a lot. Bottom line? If battery life is important, the iPhone 6s Plus is the one to go for.

iPhone 6s vs iPhone 6s Plus Pricing 

Is it advisable to buy an iPhone 6s in 2019, five years after the phones’ original release dates? If you’re after a cheap iPhone, then, yes, there is some benefit to buying an iPhone 6s or iPhone 6s Plus in 2019.

However, neither are included inside our Best iPhone: Your Definitive Guide. Why? Simple: they’re too old. You can pick up both the iPhone 7 and iPhone 8 for not much money now, so you’re 100% better off going with one of them.

If you want an even newer model, say, the iPhone X, but you don’t want to pay full chat for the handset, you could buy a refurbished iPhone X and save yourself around 40% off the RRP in the process.

My advice? If you want to go the refurbished iPhone route, make sure you read our Guide on Buying Refurbished iPhones: Everything You Need To Know & What To Expect.
