iPhone 6s - The Longest iOS Update History In Apple, Still Getting iOS 15

Its been almost a six-year since Apple announced the iPhone 6s in September 2015, but Apple surprised everyone who owned the iPhone 6s by announcing iOS 15 at WWDC 2021 virtual online event and getting support for iOS 15 on the iPhone 6s, including iPhone 6s Plus and so as the iPad Air 2 getting iPadOS 15, this makes the iPhone 6s – The longest software support phone in iPhone history.

Despite iOS 15 is not a major update, it brings some major improvements to SharePlay, iMessage, revamped notifications, Live text, and Safari improvements including a new tab bar design and search bar now move to the bottom and other features to FaceTime. (see more about iOS 15)

However, because of most of the fun new capabilities, such as offline Siri and image-to-text recognition, unfortunately, the iPhone 6s does not support them (requires an iPhone with an Apple A12 Bionic or later chip). Apple just included the functions that A9 could handle and left the rest out. The clever decision to limit the iPhone 6s to only use functions is one of the reasons it has become the king of longevity. The iPad Air 2 and iPadOS 15 are in the same situation.

In the iPhone 6 and 6s, the update from Apple’s A8 to A9 chip was not as substantial as the RAM update. Despite this, the A9 delivered the iPhone 6s a 70 percent performance improvement over the iPhone 6. In terms of GPU performance, the 6s outperformed the old model by a stunning 90%.

The iPhone 6s’ processing power was far superior to that of any other smartphone at the time. The high-performance A9 and A8x chips provided enough power for the iPhone 6s and iPad Air 2 to function properly even after six years of use.

The iPhone 6s has a RAM capacity of 2GB, which is double that of the previous model i.e. iPhone 6. This was a significant move for Apple at the time. In order to improve efficiency, Apple does not include a lot of RAM in their smartphones.

However, the iPhone 6s’ incorporation of 2GB RAM in 2015 allowed it to maintain its usability in 2021. Though 2GB RAM isn’t much in 2021, the iPhone 6s was able to obtain the newest iOS 15 updates, just like the iPad Air 2, because of its efficiency.
