Sony Replaces 7-Year Model Number Pattern

0

Sony seems to have changed the model number pattern it has used to enumerate smartphone models since 2013 on phones it launched in 2020. Instead of old numbering consisting of one letter and three numbers, the numbering consisting of four letters and two numbers came.

Sony had a standard model numbering system for Xperia smartphones that it has released since 2013. This model numbering; It consisted of a five-digit sequence by combining one letter and four numbers. For example, the model numbers of the 2019 Xperia 1 were J8110, J8170, J9110, while the model numbers of the 2013 Xperia Z were C6602, C6603, C6606.

The first character in this numbering was the letter, pointing to the year. In other words, the point of the model shifts forward in every new year; While the models in 2013 were specified with ‘C’, those in 2014 were identified with ‘D’, so this continued. The first two numbers indicated how outstanding the device was, while the last number indicated the network configuration. Apparently, Sony seems to have changed this numbering pattern with the 2020 models.

Model numbers consisting of six characters:
When we look at the model numbers of the 2020 Sony Xperia devices announced to date, we see a pattern consisting of four letters and two numbers. For example, the model numbers of the flagship Xperia 1 II XQ-AT51 / XQ-AT52, model numbers of the mid-range Xperia 10 II XQ-AU51 / XQ-AU52, the model numbers of the budget Xperia L4 XQ-AD51 / XQ-AD52 It was described as.

Although it is not yet clear what the letters and numbers in the pattern indicate, it is thought that ’51’ and ’52 indicate whether the device has a single or dual SIM input. Since all devices start with ‘XQ’, these letters can be estimated to determine the year. On more elite devices, for example Xperia 1 II and Xperia 10 II, the second batch of letters is ‘AT’ and ‘AU’, while the budget-friendly Xperia L4 consists of ‘AD’.
