Display Comparison
Neither device’s display specifications are provided, so a direct comparison is limited. However, given the price points, both likely utilize LCD panels. The Oppo A9 (2020) likely benefits from Oppo’s established display calibration expertise, potentially offering slightly more accurate colors. Bezels are expected to be comparable, reflecting the budget nature of both devices.
Camera Comparison
The context data for the Oppo A9 (2020) mentions a camera, but provides no specifics. Given Oppo’s marketing history, it likely features a multi-camera setup with a primary sensor, ultra-wide, and depth sensor. The Doogee Blade20’s camera specifications are also absent. Without sensor size or aperture information, a meaningful comparison is impossible. It’s reasonable to assume both phones will perform adequately in good lighting conditions, but struggle in low light.
Performance
The Doogee Blade20’s Unisoc T7200 (12nm) and the Oppo A9 (2020)’s Snapdragon 665 (11nm) represent different architectural approaches. While the Snapdragon 665’s Kryo 260 Gold cores clock higher at 2.0 GHz versus the T7200’s 1.6 GHz Cortex-A75 cores, the Unisoc chip benefits from a more modern architecture. The T7200’s Cortex-A75 cores offer a performance uplift over the older Cortex-A53 cores found in the Snapdragon 665. Real-world performance will likely be similar for everyday tasks, but the T7200 may exhibit slightly better multi-core performance. The 12nm process node of the Unisoc T7200 is slightly less efficient than the 11nm of the Snapdragon 665, but this difference is unlikely to be significant.
Battery Life
The Doogee Blade20’s 85-hour endurance rating is a significant advantage over the Oppo A9 (2020)’s 69-hour rating. This translates to nearly a full day of additional usage. Furthermore, the Blade20’s stated 1100 charge cycles suggest superior long-term battery health. The Oppo A9 (2020) offers 10W wired charging and reverse wired charging, a feature absent on the Blade20. However, the slower charging speed means a full charge will take considerably longer than the Blade20’s 18W charging, even if the Blade20’s battery capacity is unknown.
Buying Guide
Buy the Doogee Blade20 if you need a phone that can reliably last through two full days of moderate use, or if you frequently find yourself away from a power outlet. It’s ideal for travelers, field workers, or anyone who dislikes daily charging. Buy the Oppo A9 (2020) if you prefer the Qualcomm ecosystem and potentially better app compatibility, and if you value the convenience of reverse wired charging, even at the cost of battery endurance.
Frequently Asked Questions
❓ Is the Unisoc T7200 chipset in the Doogee Blade20 capable of handling demanding games like PUBG?
While the Unisoc T7200 isn't a flagship chipset, its Cortex-A75 cores should allow for playable performance in PUBG at medium settings. However, expect some frame drops and potential thermal throttling during extended gaming sessions. The Snapdragon 665 in the Oppo A9 (2020) will likely offer similar gaming performance.
❓ How much faster is the 18W charging on the Doogee Blade20 compared to the 10W charging on the Oppo A9 (2020)?
18W charging is significantly faster than 10W. While exact 0-100% times are unavailable, the Doogee Blade20 will likely charge from 0% to full in approximately 2-3 hours, while the Oppo A9 (2020) could take 4-5 hours. This difference is substantial for users who need a quick power boost.
❓ Does the Oppo A9 (2020)'s reverse wired charging work with all devices?
The Oppo A9 (2020)'s reverse wired charging is compatible with most devices that charge via USB, including smartphones, Bluetooth headphones, and smartwatches. However, charging speeds will be limited by the Oppo A9 (2020)'s 10W output and the receiving device's charging capabilities.
