My Choice
If I were choosing between these two phones, I would pick the Motorola Edge 20. Even though the Oppo A15 might have slightly better battery life in some situations and has a macro lens, the overall user experience on the Edge 20 will be significantly better.
Here's why:
- Performance: The Snapdragon 778G is a much more powerful chipset. This means apps will open faster, games will run smoother, and multitasking will be a breeze. The Oppo A15's Helio P35 will feel sluggish in comparison, especially over time as apps become more demanding.
- Display: The 144Hz OLED display on the Edge 20 is a game-changer. The higher refresh rate makes everything from scrolling through social media to playing games feel much smoother and more responsive. The OLED technology also offers superior color accuracy and contrast compared to the A15's LCD.
- Camera: The Edge 20's camera system is vastly superior. The 108MP main sensor captures much more detail, and the addition of a telephoto lens provides more flexibility for taking photos at different focal lengths. The ability to record 4K video is also a significant advantage. I'd rather have an ultra-wide camera than a macro lens.
- Software: The newer version of Android on the Edge 20 means I'll get more up-to-date features and security patches.
While the Oppo A15 is likely more affordable, the Motorola Edge 20 offers a much better overall value. The improvements in performance, display, camera, and software justify the higher price tag, making it a worthwhile investment for anyone who uses their smartphone regularly for more than just basic tasks.
