iPhone 6s devices, longest to receive operating system updates

The recent release of iOS 15.5 to iPhone 6s is not a surprise to owners as they may have known it from last year when it was announced that iOS 15 will still be available for these devices. Indeed, the longest software update, according to The Verge, for a smartphone.

If you are one of those who still hold dear such device, kept and taken care of with the same shiny look when it was bought, not a mat and scratch allowed on the surface, you would know that there had been one single major issue as you are about to run the update. Not enough storage. 

In order to get past storage limit, you'd delete apps and data until it already has the minimum space to continue the update. A factory reset is inevitable to others, due to the fact that even after deleting all data including big multimedia files, it is still deficient of storage space. 

Don't forget to backup your most treasured data though, before deleting all content or resetting the entire system, to other devices such as your computer, handheld or flash drive with higher storage capacity.  

Just install the apps again afterwards. If app data were allowed to be backed up to iCloud, then they'll be synchronized almost immediately after the app has been installed.

So far the only problem we've encountered is the storage space. Hardware performance didn't change a bit.  Battery is fine. The circular touch ID area has no sign of deterioration. A frequent crashes of software or restart of device may mean something more and that the a new iOS might need to be loaded. It happens when a device has been infested with malware, storing malicious data or if could not reach or being rejected by update server. 

With a little care or if we purposely tend to how the devices are dealt with and used, we may see a longer life or service than their contemporary.
