If you’re puzzling over which iPhone you should buy, but you lack the funds for a new model, then you may be tempted to pick up an older iPhone. Apple continues to support iPhones for several years after release, and they tend to perform well for a long time. The oldest iPhone that Apple now sells is the iPhone XR, making both the iPhone 6 and iPhone 6S a bit long in the tooth. If you’re choosing between the two devices, though, we’re happy to help you decide.
The successor to Apple’s iPhone 6 was the iPhone 6S. It looks identical to its predecessor, so you may be wondering what the difference is. Below, we spell out the hardware specifications of both iPhones and dip into an analysis of the categories where you’re likely to see the biggest differences.

Performance, battery life, and charging
Every new iPhone is faster than those that came before, and the iPhone 6S is no exception. Apple jumped from the A8 chipset that was in the iPhone 6 to its A9 chipset. Similarly, the 6S upgraded from the M8 coprocessor to the M9. These upgrades translate to faster processing speeds — about 70 percent faster, according to Apple. The
The iPhone 6S actually has a smaller battery than the iPhone 6, but the more efficient processor balances things out and it tends to last a bit longer on an average day. Both charge via the Lightning port and take a similar length of time to juice up.

Design and durability
In terms of look and size, there isn’t much of a difference between the two, in fact, you’ll struggle to tell them apart. The iPhone 6S is 0.01 inches thicker and half an ounce heavier, but those are hardly noticeable differences. Both phones are 5.44 inches tall by 2.64 inches wide, and both feature a 4.7-inch display. Both have the headphone jacks, a Lightning port for charging, and that iconic Touch ID home button that was a feature of iPhones for many years.
Both phones are aluminum, so they’re pretty tough, but the iPhone 6S is built from superior Series 7000 aluminum, which should be a little stronger. This change may have been a response to the bendgate furor around the iPhone 6 Plus.
Both of these iPhones have a 4.7-inch display with a 1334 x 750-pixel resolution, which works out to 326 pixels per inch. There’s no dividing them here. Only the 6S has Apple’s 3D Touch technology, but we’ll deal with that in the special features section below. Visually speaking, there’s no difference between these displays.
The iPhone 6S blows the iPhone 6 out of the water in the camera department with a seriously beefed-up main camera and a much-improved selfie camera. The main camera is rated at 12 megapixels, up from 8 megapixels, and the front-facing camera has jumped to 5 megapixels from a woefully inadequate 1.2 megapixels. The 6S is also capable of shooting 4K resolution video, while the iPhone 6 is limited to 1080p. You can expect to capture much better photos with the

Software and updates
Initially, the iPhone 6 launched with iOS 8, and the iPhone 6S launched with iOS 9. Since then, the iPhone 6 has maxed out with iOS 12, but the

Immediately apparent is the inclusion of the 3D touch feature on the iPhone 6S. Essentially, 3D Touch is enabled by a pressure-sensitive screen that can pick up on how hard you press the display. You can lightly press to peek into things, for example lightly pressing on a photo in your gallery will give you a pop-up preview. You can press harder to pop straight into the content.
The iPhone 6S also supports a slightly newer and better Bluetooth version and it comes in Rose Gold, which is not an option with the iPhone 6.

Price and availability
If you want to buy an iPhone 6S or an iPhone 6 today, then you’ll likely be buying a refurbished handset or a used phone. Prices vary widely, but you can pick up an iPhone 6 starting from around $110 and an

There’s no doubt that the iPhone 6S is a better phone. There isn’t a huge gap between them; the main differences are the improved performance and the better cameras in the
