BLU J6 2020

  • Potentially lower price point
  • Simple and straightforward user experience
  • May be more readily available in certain markets

  • Significantly slower processor
  • Less efficient power consumption
  • Outdated architecture

BLU G51

  • Faster and more responsive processor
  • More efficient power consumption
  • Modern chipset architecture

  • May be slightly more expensive
  • Still limited in terms of overall performance
  • Camera quality likely remains basic

Display Comparison

Neither BLU provides detailed display specifications. However, given their price points, both likely utilize LCD panels with 720p+ resolutions. The G51’s advantage isn’t likely in display quality, but rather in the chipset’s ability to drive the display more efficiently. Expect similar viewing angles and color accuracy on both devices, with neither offering features like high refresh rates or HDR support.

Camera Comparison

Both devices likely feature basic camera setups. Without specific sensor details, it’s safe to assume both rely on low-resolution primary sensors. The G51’s chipset may offer slightly better image signal processing (ISP) capabilities, potentially resulting in marginally improved image quality in good lighting conditions. However, don’t expect flagship-level camera performance from either device. The inclusion of a 2MP macro lens on either device is largely a marketing tactic and offers limited practical benefit.

Performance

The core difference lies in the chipsets. The BLU J6 2020’s Quad-core 1.3 GHz Cortex-A7 is based on an older ARM architecture. In contrast, the BLU G51 features the Mediatek MT6761 Helio A22, a Quad-core 2.0 GHz Cortex-A53 processor built on a more efficient 12nm process. This translates to approximately a 50-60% performance increase for the G51 in CPU-bound tasks. The A53 architecture also offers improved instructions per clock cycle, leading to better overall responsiveness. While neither phone is a gaming powerhouse, the G51 will handle less demanding titles with greater fluidity.

Battery Life

Battery capacity details are unavailable for both devices. However, the Helio A22’s 12nm process offers better power efficiency than the Cortex-A7. This means the BLU G51 is likely to achieve slightly longer battery life on a single charge, despite potentially having a similar battery capacity. Charging speeds are also likely to be slow on both devices, given their budget nature.

Buying Guide

Buy the BLU J6 2020 if you absolutely need the lowest possible price point and your usage is limited to calls, texts, and very light app usage. Buy the BLU G51 if you prefer a more responsive experience for social media, basic gaming, and everyday tasks, even if it means spending a bit more.

Frequently Asked Questions

❓ Will the BLU G51 handle popular social media apps like Facebook and Instagram smoothly?
Yes, the Mediatek Helio A22 chipset in the BLU G51 provides enough processing power to run social media apps like Facebook and Instagram without significant lag. While it won’t offer a high-end experience, it will be noticeably smoother than the BLU J6 2020.
❓ Is the BLU J6 2020 suitable for playing mobile games?
The BLU J6 2020 is only suitable for very basic mobile games. Its Cortex-A7 processor will struggle with most modern titles, resulting in low frame rates and frequent stuttering. The BLU G51 offers a slightly better gaming experience, but still isn’t ideal for demanding games.
❓ How much storage does each phone offer, and can it be expanded?
Storage details are not provided. However, given the price point, both devices likely offer limited internal storage (16GB or 32GB). Both are expected to include a microSD card slot for storage expansion, allowing users to add more space for photos, videos, and apps.
❓ What version of Android do these phones run?
Both devices likely run an older version of Android (potentially Android 9 or 10) with a customized BLU UI. Updates are unlikely to be frequent or guaranteed, given their budget nature.
