Display Comparison
Both devices utilize a 12nm process, suggesting similar power efficiency considerations in display manufacturing. However, specific display specs like resolution, panel type (IPS vs. AMOLED), and brightness are not provided. Given the Spark 3 Pro’s positioning, it likely features a standard IPS LCD. The Spark 40C, being a newer model, *may* have a slightly improved panel, but without concrete data, it’s difficult to assess. Bezels are likely comparable, reflecting the budget nature of both phones.
Camera Comparison
Without detailed camera specifications beyond the presence of sensors, a direct comparison is limited. It’s reasonable to assume the Spark 40C benefits from improved image signal processing (ISP) capabilities integrated within the Helio G81 chipset. This could result in better dynamic range and noise reduction. The Spark 3 Pro likely relies on a simpler ISP, resulting in less refined image quality. The presence of a 2MP macro lens on either device is unlikely to be a significant selling point, as image quality from such sensors is typically limited.
Performance
The core difference lies in the chipset. The Tecno Spark 3 Pro’s MediaTek Helio A22, with its quad-core Cortex-A53 CPU clocked at 2.0 GHz, is designed for basic tasks. The Spark 40C’s Helio G81 is a substantial upgrade, featuring an octa-core configuration with 2x 2.0 GHz Cortex-A75 cores and 6x 1.8 GHz Cortex-A55 cores. This architecture provides significantly improved multi-core performance and responsiveness. The Cortex-A75 cores offer a noticeable boost in single-core performance, crucial for app launch speeds and general UI fluidity. While both are 12nm, the G81’s architecture is far more capable, translating to a smoother user experience, especially when multitasking or running more demanding apps.
Battery Life
Battery capacity isn’t specified for either device. However, the Spark 40C’s inclusion of 18W wired charging is a key advantage. While the battery size may be similar, the faster charging speed will significantly reduce the time required to replenish the battery, offering greater convenience. The Spark 3 Pro likely supports standard 10W charging, resulting in a considerably longer charge time.
Buying Guide
Buy the Tecno Spark 3 Pro if you absolutely need the lowest possible price point for basic communication tasks like calls, texts, and light social media use. It's a functional device for minimal smartphone requirements. Buy the Tecno Spark 40C if you value smoother performance, enjoy mobile gaming even on modest settings, or appreciate faster charging – it’s a worthwhile investment for a more responsive and versatile experience.
Frequently Asked Questions
❓ Will the Tecno Spark 40C run demanding games like PUBG Mobile smoothly?
The Helio G81 is capable of running PUBG Mobile, but likely at medium settings to maintain a stable frame rate. The A22 in the Spark 3 Pro would struggle significantly with this title. Expect a more enjoyable gaming experience on the 40C, though it won't rival dedicated gaming phones.
❓ Is the 18W charging on the Spark 40C a significant improvement over the Spark 3 Pro?
Yes, it is. Standard 10W charging can take several hours to fully charge a smartphone. 18W charging will noticeably reduce this time, allowing you to get back to using your phone much faster. While a precise 0-100% time isn't available, expect a reduction of at least 30-60 minutes.
❓ Does the Spark 40C have better RAM management than the Spark 3 Pro?
The Helio G81's improved architecture and potentially larger RAM capacity (specs not provided) contribute to better RAM management. This means the Spark 40C can keep more apps open in the background without slowing down, resulting in a smoother multitasking experience.
