As OnePlus prepares to unveil the OnePlus 15T in China on March 24, attention inside the company’s lineup is already shifting toward what comes next. Industry chatter now points to an April expansion of the Ace 6 series, with a new model expected to carry the “Ultra” name for the first time in this range.

The Ace 6 Ultra is being positioned as a performance-focused device, continuing a strategy OnePlus has followed in its Ace lineup, particularly for the Chinese market. While the Ace 6 and Ace 6T are still relatively fresh entries, the addition of an Ultra variant suggests the brand is leaning into higher-end specifications to compete in an increasingly crowded segment.

Early details indicate the phone will feature a 6.8-inch display with a 165Hz refresh rate. That specification, if confirmed, would place it among the fastest panels currently available on smartphones, targeting users who prioritize fluid scrolling and gaming responsiveness.

Under the surface, the device is expected to run on the MediaTek Dimensity 9500 chipset. This marks a continuation of OnePlus’s collaboration with MediaTek in performance-tier devices, a shift that has gained traction as newer Dimensity chips close the gap with traditional flagship processors.

Certification Hints And Market Positioning

There are also signs that the device is already moving through regulatory steps. A phone with model number PMK110 has appeared in China’s SRRC certification database, associated with Oppo and OnePlus. It remains unclear whether this listing directly corresponds to the Ace 6 Ultra, but the timing aligns with the expected launch window.

If the April debut materializes, the Ace 6 Ultra will likely enter direct competition with devices such as the Redmi K90 Ultra, another performance-oriented phone expected to use the same Dimensity 9500 platform. That overlap suggests a familiar rivalry between OnePlus and Xiaomi’s Redmi brand in the high-performance segment.

At this stage, there is no confirmation regarding availability outside China. The Ace series has historically remained focused on the domestic market, though select models have occasionally been rebranded for international release under different names.

Alongside its smartphone plans, OnePlus is also said to be preparing new tablets, including the OnePlus Pad 3 Pro and a more compact Pad Mini. Both have reportedly received certifications in China, indicating a broader product push that may coincide with the upcoming launches.

For now, the Ace 6 Ultra remains part of a carefully timed rollout. With multiple devices lining up across categories, April could become a busy month for OnePlus as it reinforces its presence in both performance smartphones and the wider ecosystem it is gradually building.
