Huawei Mate 30 5G

  • Significantly faster 40W wired charging
  • Superior wireless and reverse wireless charging capabilities
  • Potentially more advanced camera processing due to Kirin 990 5G’s NPU

  • EMUI software may not appeal to all users
  • Potential 5G band limitations depending on region

Samsung Galaxy S20 5G UW

  • Stronger CPU and GPU performance with Snapdragon 865
  • Wider 5G band support for greater compatibility
  • More refined and widely adopted One UI software experience

  • Slower 25W wired charging
  • Lower wireless charging speed (15W)

Display Comparison

While both devices feature OLED panels, specific details like resolution and refresh rate aren't provided. However, the focus here is on processing power. The Samsung S20 5G UW likely benefits from the Snapdragon 865’s image signal processor (ISP) for potentially more accurate color reproduction and faster image processing from the display. The lack of detailed display specs makes a direct comparison difficult, but Samsung historically excels in display technology.

Camera Comparison

Without detailed sensor specifications, a direct camera comparison is challenging. However, Huawei historically prioritizes computational photography, and the Kirin 990 5G’s dedicated Neural Processing Unit (NPU) likely plays a significant role in image processing. The Snapdragon 865 also has a powerful ISP, but Samsung’s image processing tends to be more natural, while Huawei often aims for more vibrant, saturated results. The absence of information on sensor sizes and lens apertures prevents a definitive judgment, but Huawei’s reputation for camera innovation suggests a strong contender.

Performance

The core of the difference lies in the chipsets. The Samsung Galaxy S20 5G UW’s Snapdragon 865 (7nm+) boasts a Cortex-A77 prime core clocked at 2.84 GHz, while the Huawei Mate 30 5G utilizes the Kirin 990 5G (7nm+) with a slightly higher clocked Cortex-A76 (2.86 GHz). However, the Snapdragon 865’s architecture, particularly its Adreno 650 GPU, generally delivers superior graphics performance. The Kirin 990 5G’s CPU configuration, with two A76 cores, is balanced, but the Snapdragon’s single, faster A77 core and three additional A77 cores provide a performance advantage in multi-threaded tasks. Both utilize LPDDR4X RAM, but the Snapdragon’s optimized memory controller contributes to overall system responsiveness.

Battery Life

The Huawei Mate 30 5G’s 40W wired charging is a clear advantage over the Samsung Galaxy S20 5G UW’s 25W charging, promising significantly faster top-ups. The Mate 30 5G also offers 27W wireless charging and reverse wireless charging, while the S20 5G UW is limited to 15W wireless (Qi) and 4.5W reverse wireless. While battery capacity isn’t specified, the faster charging speeds of the Mate 30 5G mitigate any potential capacity disadvantage, offering more convenient power management for users on the go.

Buying Guide

Buy the Huawei Mate 30 5G if you prioritize exceptionally fast charging (40W wired, 27W wireless) and are comfortable with Huawei’s EMUI software, potentially benefiting from their advanced camera algorithms. Buy the Samsung Galaxy S20 5G UW if you value a more universally compatible 5G experience, a smoother software experience with One UI, and a slightly more powerful processor for demanding tasks like gaming and video editing.

Frequently Asked Questions

❓ Does the Kirin 990 5G in the Mate 30 5G suffer from significant thermal throttling during extended gaming sessions?
While the Kirin 990 5G is a capable chipset, it's known to be more prone to thermal throttling compared to the Snapdragon 865, particularly under sustained heavy loads like prolonged gaming. The Snapdragon 865’s more efficient architecture and potentially better thermal management design in the S20 5G UW contribute to more consistent performance over longer periods.
❓ Is the lack of Google Mobile Services (GMS) on the Huawei Mate 30 5G a dealbreaker for most users?
The absence of GMS was a significant drawback for the Mate 30 5G at launch. While Huawei has attempted to mitigate this with its Huawei Mobile Services (HMS) and AppGallery, the app ecosystem is still less mature than Google’s. Users heavily reliant on Google apps like Gmail, YouTube, and Google Maps may find the experience cumbersome or require workarounds.
❓ How does the 5G performance differ between the Mate 30 5G and the S20 5G UW, considering the different modems?
The Samsung Galaxy S20 5G UW utilizes Qualcomm’s Snapdragon X55 5G modem, offering broader 5G band support, including mmWave, which provides significantly faster speeds but limited coverage. The Mate 30 5G’s integrated 5G modem supports sub-6GHz 5G, which has wider coverage but lower peak speeds. The S20 5G UW is therefore better suited for areas with mmWave 5G infrastructure.
