The Sony Xperia 1 IX has just appeared in the GSMA IMEI database with three model numbers, suggesting the company is preparing a product for 2027.
Sony appears to be taking a step further in developing its next flagship smartphone, the Xperia 1 IX. According to information from the Japanese website S-Max, three new model numbers have been discovered in the GSMA IMEI database, indicating that this successor is currently under development.
The Xperia 1 IX has made important preparations for its launch next year.
The recorded product codes include XQ-HH44 (exclusive to the Japanese market, supporting eSIM), XQ-HH54 (for Europe), and XQ-HH74 (for other markets, including China). According to Sony's convention, the "H" at the beginning of the product code indicates the year of manufacture as 2027, while the "4" at the end confirms eSIM support. The accompanying internal names are PM-1545-BV, PM-1540-BV, and PM-1541-BV. Notably, the Japanese version is also said to be compatible with 3GPP satellite communication standards.
The Walkman Blog also notes that the Xperia 1 VIII appeared in the database in November 2025, while the Xperia 1 VII was recorded in October 2024. Although the early listing of the Xperia 1 IX doesn't necessarily mean it will launch sooner, it suggests Sony is actively developing the next generation of this product line.
Three different versions of the Xperia 1 IX have been reported.
Sony has maintained a consistent annual release cycle for the Xperia 1 series, albeit with lower production volumes compared to its major competitors. The Xperia 1 IX is expected to continue focusing on screen quality, photography capabilities, and powerful audio features.
However, one factor to consider is price. The current DRAM shortage could drive up component prices, potentially leading to price increases when the Xperia 1 IX launches next year. Currently, no other specifications have been leaked, but the confirmation of the model number suggests that initial planning and legal work has begun. More details about the Xperia 1 IX are expected closer to its launch date in 2027.
