- More power-efficient Snapdragon 695
- Slightly slower charging speed
- Image processing may be less vibrant
Display Comparison
The Motorola Moto G84 boasts a significantly brighter display, reaching a measured 996 nits. This is a substantial advantage over what we’d expect from the A78, making the G84 far more usable in direct sunlight. While the A78’s display specs are not provided, the G84’s brightness alone is a major selling point. The G84’s panel likely benefits from a more modern manufacturing process, contributing to its superior luminance. Bezels are expected to be similar on both devices given their price point, and color accuracy is likely to be adequate for everyday use on both.
Camera Comparison
Detailed camera specs beyond 'Photo / Video' are absent for both devices. However, given the price bracket, we can assume both rely on primary sensors around the 50MP mark. The Moto G84’s image processing is likely tuned for a more natural look, typical of Motorola, while Oppo often favors more vibrant, saturated colors. Without further information, it’s difficult to declare a clear winner. The presence or absence of Optical Image Stabilization (OIS) on either device would be a significant differentiator, but this data is unavailable.
Performance
Both phones utilize octa-core CPUs clocked at 2.2 GHz, but the underlying architecture differs. The Oppo A78’s Mediatek Dimensity 700 (7nm) employs Cortex-A76 cores, known for their strong single-core performance, paired with Cortex-A55 efficiency cores. The Motorola Moto G84’s Qualcomm Snapdragon 695 5G (6nm) uses Kryo 660 Gold and Silver cores. The 6nm process node of the Snapdragon 695 generally translates to better power efficiency compared to the 7nm Dimensity 700, potentially leading to longer sustained performance. However, real-world performance differences will likely be minimal for typical tasks. Neither chipset is a gaming powerhouse, but both can handle casual gaming adequately.
Battery Life
The Motorola Moto G84 clearly wins in battery endurance. Its active use score of 12:31h and endurance rating of 117h demonstrate significantly longer battery life than the Oppo A78. While the A78 offers faster 33W charging (52% in 30 minutes, 100% in 67 minutes), the G84’s 30W charging is sufficient given its larger battery capacity and superior efficiency. The G84’s 6nm chipset contributes to this efficiency, allowing it to extract more usage from each charge.
Buying Guide
Buy the Oppo A78 if you prioritize the absolute fastest charging speeds and are frequently near a power outlet. Its 33W charging gets you to 52% in 30 minutes, a slight edge over the Moto G84. Buy the Motorola Moto G84 if you value all-day battery life, a vibrant and bright display for outdoor use, and a more balanced overall package. It’s the better option for users who don’t want to constantly worry about battery percentage.
