Google’s Vice President of Devices and Services, Seang Chau, shed light on the upgrade promise on the company’s Made by Google podcast. According to Chau, Google’s shift to using custom Tensor processors in recent smartphones partially enabled it to offer better software support. It started with the initial increase from three to five years of support and now from five to seven.
The choice to offer a seven-year promise was no accident. Google looked at how long the original Pixel remained in use and found that there were still a significant number of active users until roughly seven years after its initial release. This was the basis for Google’s decision to go with seven years of support.
The chipset is one of the most complex factors in supporting older devices with new software, according to Chau. However, other reasons Google thinks it can deliver this long of a promise are its continuous lab testing and beta testing thanks to Android’s new Quarterly Platform Releases (QPRs).
