Display Comparison

The OnePlus Open boasts a significantly brighter display, reaching a measured 1238 nits, compared to the Mate X2’s unspecified peak brightness. This translates to better outdoor visibility. While both are foldable OLED panels, the OnePlus Open likely benefits from newer panel technology, potentially offering improved color accuracy and viewing angles. The OnePlus Open’s larger display area also provides a more immersive experience. The Mate X2’s outward fold, while visually striking, is more prone to accidental screen contact and potential damage.

Camera Comparison

Context data is limited regarding camera specifics. However, given the market positioning, the OnePlus Open likely features a more advanced camera system. While the Mate X2 likely has a competent setup, the Snapdragon 8 Gen 2’s image signal processor (ISP) offers superior image processing capabilities, including better noise reduction and dynamic range. The OnePlus Open’s camera is described as 'Photo / Video', suggesting a focus on both stills and video recording quality. We can assume the OnePlus Open will have more advanced computational photography features.

Performance

The core difference lies in the chipsets. The OnePlus Open’s Qualcomm Snapdragon 8 Gen 2 (4nm) is a substantial upgrade over the Huawei Mate X2’s Kirin 9000 (5nm). The Snapdragon 8 Gen 2 features a newer CPU architecture – Cortex-X3 prime core at 3.2 GHz versus the Mate X2’s Cortex-A77 at 3.13 GHz – resulting in faster processing speeds and improved efficiency. The 4nm process node of the Snapdragon further enhances thermal management, reducing throttling during sustained workloads like gaming. This means the OnePlus Open will maintain higher frame rates for longer periods. The Kirin 9000, while capable, is showing its age against the latest silicon.

Battery Life

The OnePlus Open demonstrates a clear advantage in battery performance, achieving an impressive 11:59 hours of active use and an endurance rating of 96 hours. While the Mate X2’s battery capacity is unknown, the OnePlus Open’s 67W charging with full charge in 42 minutes is significantly faster than the Mate X2’s 55W wired charging. The Snapdragon 8 Gen 2’s improved power efficiency also contributes to the OnePlus Open’s longer battery life. The inclusion of reverse wired charging on the OnePlus Open adds further convenience.

Buying Guide

Buy the Huawei Mate X2 4G if you prioritize a unique, outward-folding design and are comfortable with a slightly older chipset. It's a good option for those seeking a statement piece and aren't heavily reliant on demanding mobile gaming. Buy the OnePlus Open if you value top-tier performance, long battery life (11:59h active use), fast charging (67W, 42min to 100%), and a brighter, more modern display. It’s ideal for power users, gamers, and those who want a reliable and feature-rich foldable.

Frequently Asked Questions

❓ Does the Kirin 9000 in the Mate X2 struggle with demanding games like Genshin Impact?
The Kirin 9000 is a capable chipset, but the Snapdragon 8 Gen 2 in the OnePlus Open offers significantly better sustained performance. Expect more noticeable frame drops and potential throttling in graphically intensive games on the Mate X2, especially during extended play sessions.
❓ How does the outward-folding design of the Mate X2 affect its durability compared to the OnePlus Open’s inward fold?
The Mate X2’s outward-folding design exposes the screen when folded, making it more susceptible to scratches and damage from accidental contact. The OnePlus Open’s inward fold protects the display when closed, offering greater peace of mind.
❓ Is the 67W charging on the OnePlus Open truly as fast as advertised?
Yes, the OnePlus Open’s 67W charging can deliver a full charge in approximately 42 minutes, as stated in the specifications. This is a significant improvement over the Mate X2’s 55W charging, reducing downtime and keeping you powered up throughout the day.
❓ What kind of software support can I expect from OnePlus for the Open, considering their track record?
OnePlus has improved its software support in recent years, promising at least 3 major Android updates and 4 years of security patches for the Open. This is comparable to other flagship devices and ensures your phone remains secure and up-to-date for a considerable period.
