My Choice and Why
If I were choosing between these two phones, I would absolutely choose the Huawei Pura 70 Ultra.
Here's why:
- The difference in overall performance is staggering. The Kirin 9010 chipset and 16GB of RAM mean the Pura 70 Ultra will handle any task I throw at it with ease, while the A02's chipset would feel laggy and limiting.
- I prioritize a high-quality display. The OLED panel, higher resolution, 120Hz refresh rate, and high brightness of the Pura 70 Ultra mean I'd enjoy using my phone for everything from browsing to watching videos. The A02's LCD screen would feel outdated and low quality.
- I care about taking great photos. The Pura 70 Ultra's camera system, with its 1-inch sensor, wide aperture, telephoto lens, and wide-angle lens, would enable me to capture high-quality photos and videos in various conditions, while the A02 would be a very limited camera.
- I need fast charging and better features. The Pura 70 Ultra's fast charging, wireless charging, and comprehensive sensor suite make it a much more convenient and versatile device.
- I prefer a phone that has more features, more capabilities and is enjoyable to use. While the A02 may be sufficient for basic usage, the user experience would simply not be enjoyable.
While the weight and likely higher cost are trade-offs, the significant improvements in performance, display quality, camera capabilities, and overall user experience of the Pura 70 Ultra are well worth the extra investment for my needs. The A02 is simply too basic for a modern user and would be limiting and frustrating to use as a daily driver.
