Core Difference between iPhone 6 and iPhone 6S

If you are wondering which iPhone to buy, but do not have the funds for the new model, you might just for the older iPhone since Apple continues to support iPhones for several years after their release. At the moment, the oldest iPhone Apple still sells, is the iPhone 7 but you might still want to go for the successors, iPhone 6 and iPhone 6S.

The two look identical and you might be wondering what the difference is. Below we spell out the differences between the iPhone 6 and iPhone 6S in the various categories.


Performance, Battery Life, and Charging

Usually, all the newer iPhones are faster than the ones that came before and for the iPhone 6 and iPhone 6S, there is no exception. iPhone 6S is faster because Apple jumped from the A8 chipset to the A9 chipset. The processor for the iPhone 6S was also upgraded from the M8 coprocessor to the M9. Therefore, the iPhone 6S has faster processing speeds, up to 70% faster according to Apple.

The iPhone 6S also has 2GB of RAM which is double the RAM in the iPhone 6 which means the iPhone 6S is noticeably faster than the iPhone 6 during most tasks. iPhone 6S has a smaller battery than the iPhone 6, with a more efficient processor making the battery last longer. However, both of the phones charge via the lightning port and take the same amount of time to charge up.

Design and Durability

In terms of look and size, the iPhone 6 and iPhone 6S look pretty much the same and you might not be able to tell them apart. However, the iPhone 6S is 0.01 inches thicker and half an ounce heavier than the iPhone 6. Both phones are of the same length and width, with the same display. They both have headphone jacks, a lightning port for charging, and the iconic Touch ID home button.

Both phones were made tough, with aluminum but the iPhone 6S from superior series 7000 aluminum, making it tougher than the iPhone 6.


iPhone 6 and iPhone 6S both have a 4.7-inch display with 1334×750 resolution. However, the 6S has 3D Touch technology which is one of the special features telling it apart. But from the onset, you will not see the difference between the two displays.


The iPhone 6S is better than the iPhone 6 by miles since its camera is quite beefed-up. The iPhone 6S camera is rated at 12 megapixels on the main camera, from the 8 megapixels on the iPhone 6. The front camera has also been jumped from 1.2 megapixels to 5 megapixels. Additionally, the 6S has the capability of shooting 4K resolution video while the 6 is limited to 1080p. This means the quality of the photos you will get from the 6S are much better than 6.

Software and Updates

Both the iPhone 6 and iPhone 6S has been updated to iOS 12 and, likely, they will both be updated to iOS 13. In terms of the software or update front, there is not much difference between the two phones but in the future, the 6S might get an extra update over the 6.

Special Features

The inclusion of the 3D touch feature on the iPhone 6S is immediately apparent and it is enabled by a pressure-sensitive screen. Lightly pressing the screen will give you a peek into things and pressing hard will head you straight into the content.

iPhone 6S supports a better Bluetooth version and also comes in a Rose Gold variation, which you will not enjoy with the iPhone 6.


The iPhone 6S is a better phone than the iPhone 6 but the gap between them is not huge. Improved performance in the former, better cameras and updates are some of the things you will enjoy with the iPhone 6S. Since both are cheaper now, it is recommended that you go for the 6S as it might last you longer. Go back to our home page here.
