OnePlus is reportedly in the early stages of developing a new smartphone that emphasizes exceptional battery life and performance, according to well-known tipster Digital Chat Station. The rumored device is said to feature a 6.59-inch 1.5K LTPS flat display, potentially sourced from a domestic Chinese supplier. A key highlight of this upcoming phone is its impressive 8,000mAh battery, with some leaks even suggesting that future versions or different prototypes might target capacities up to 9,000mAh. This development is being widely reported by several credible technology news outlets, including Gadgets 360, Republic World, Techlusive, and Android Headlines, all corroborating the core claims from the Weibo tipster. The reports indicate that the phone is currently undergoing internal testing and evaluation, aiming to strike a balance between power, endurance, and everyday usability. Earlier leaks also hinted at a larger 6.78-inch prototype potentially powered by a MediaTek Dimensity 9500 chipset with advanced cooling, suggesting a focus on sustained performance. While the exact branding remains unconfirmed, speculation points towards a potential OnePlus Ace 6 Ultra, typically a China-specific series, or a new model within the OnePlus Turbo lineup, which could be rebranded for global markets. The news, relevant to tech enthusiasts globally and particularly in India, highlights OnePlus's potential strategy to address consumer demand for longer-lasting smartphone batteries.
