Display Comparison

The Asus ROG Phone 3 boasts a brighter display at 719 nits compared to the P40’s 589 nits, offering better visibility outdoors. Both displays share an infinite (nominal) contrast ratio, but the ROG Phone 3’s 120Hz refresh rate provides a smoother visual experience, particularly beneficial for gaming. While both are excellent, the ROG Phone 3’s higher brightness and refresh rate give it an edge for media consumption and gaming, despite the P40’s potentially more color-accurate panel (data not provided).

Camera Comparison

Both phones feature capable camera systems, but the specifics are limited by the provided data. Both are described as 'Photo / Video' capable. Without sensor size or aperture information, a direct comparison is difficult. However, Huawei’s reputation for computational photography suggests the P40 likely excels in image processing, particularly in challenging lighting conditions. The ROG Phone 3, while capable, prioritizes other features over camera innovation. The absence of detail regarding the P40’s camera features suggests a focus on overall image quality rather than specialized modes.

Performance

The ROG Phone 3’s Qualcomm Snapdragon 865 5G+ chipset, with its Cortex-A77 prime core clocked at 3.10 GHz, demonstrably outperforms the Huawei P40’s Kirin 990 5G. The Snapdragon 865+ benefits from architectural improvements and a more efficient 7nm+ process, resulting in higher sustained performance under load. While the Kirin 990 5G’s octa-core configuration is complex, the ROG Phone 3’s simpler, more powerful core arrangement translates to a smoother gaming experience. The ROG Phone 3 also benefits from superior thermal management, preventing throttling during extended gaming sessions.

Battery Life

The Asus ROG Phone 3’s 120h endurance rating significantly surpasses the Huawei P40’s 89h rating, showcasing a substantial advantage in battery life. This difference is further amplified by the ROG Phone 3’s 30W wired charging with PD3.0 and QC4 support, compared to the P40’s slower 22.5W charging. The ROG Phone 3 also offers 10W reverse wired charging, a feature absent on the P40. This combination of larger capacity and faster charging makes the ROG Phone 3 the clear winner for users who demand all-day (and night) battery life.

Buying Guide

Buy the Huawei P40 if you need a versatile flagship with a capable camera system and a more compact form factor for everyday use. Buy the Asus ROG Phone 3 if you prioritize uninterrupted gaming sessions, demand the longest possible battery life, and appreciate features like AirTriggers and a high refresh rate display, even if it means a larger device.

Frequently Asked Questions

❓ Does the Kirin 990 5G in the Huawei P40 throttle under sustained load, like during extended gaming sessions?
While the Kirin 990 5G is a capable chipset, it is more prone to thermal throttling compared to the Snapdragon 865 5G+ in the ROG Phone 3. The ROG Phone 3’s advanced cooling system and more efficient chipset architecture allow it to maintain higher performance levels for longer periods.
❓ How much does the larger size of the Asus ROG Phone 3 impact usability compared to the Huawei P40?
The ROG Phone 3 is significantly larger and heavier than the P40, making it less comfortable to use one-handed and potentially more difficult to fit in pockets. The P40’s more compact design prioritizes ergonomics and portability.
❓ Is the 22.5W charging on the Huawei P40 slow compared to modern standards?
Yes, 22.5W is relatively slow compared to the 30W (and often faster) charging speeds offered by many modern smartphones, including the ROG Phone 3. This means the P40 will take longer to fully charge from 0% to 100%.
❓ What kind of gaming performance can I expect from the Huawei P40?
The Huawei P40 can handle most mobile games at high settings, but it may struggle with the most demanding titles at maximum settings, especially over extended periods due to potential throttling. The ROG Phone 3 is specifically engineered for optimal gaming performance.
