BLU offers affordable smartphones, but choosing between models like the J6S and G70 requires understanding where each prioritizes performance and value. The J6S represents a basic, entry-level option, while the G70 aims for a step up with a more powerful processor. This comparison dissects the key differences to help you decide which BLU phone best suits your needs.
🏆 Quick Verdict
For most users, the BLU G70 is the better choice. Its octa-core 2.0 GHz Cortex-A53 processor provides a significantly smoother experience for multitasking and app loading compared to the J6S’s quad-core 1.3 GHz Cortex-A7. While the J6S is cheaper, the G70’s performance boost justifies the price difference.

BLU J6S
- Lower price point makes it very accessible.
- Potentially longer battery life due to less powerful processor.
- Simple and straightforward user experience.
- Slow performance, especially with multiple apps open.
- Outdated processor architecture.
- Likely lower quality display.
BLU G70
- Significantly faster performance thanks to the octa-core processor.
- More responsive user interface.
- Better multitasking capabilities.
- Higher price compared to the J6S.
- Potentially shorter battery life.
- May still struggle with demanding games.
Display Comparison
Neither BLU provides display specifications in the provided data. Given their price points, both likely utilize LCD panels with 720p resolutions. The J6S, being the lower-end model, likely has narrower viewing angles and lower peak brightness. The G70 may offer slightly better color reproduction due to its higher tier positioning, but significant display improvements are unlikely. Expect both to have noticeable bezels.
Camera Comparison
Without sensor details, a direct camera comparison is difficult. However, it’s safe to assume both phones feature basic camera setups geared towards casual photography. The G70, positioned as a higher-tier device, *may* have a slightly better main sensor and image processing algorithm, resulting in marginally improved image quality in good lighting conditions. Expect both to struggle in low-light scenarios. The inclusion of a 2MP macro camera on either device is likely a marketing gimmick, offering limited practical benefit due to the small sensor size and lack of optical image stabilization.
Performance
The core difference lies in the CPUs. The BLU G70’s octa-core 2.0 GHz Cortex-A53 processor represents a substantial upgrade over the J6S’s quad-core 1.3 GHz Cortex-A7. The A53 architecture, while not cutting-edge, is more efficient and capable than the older A7. This translates to faster app launch times, smoother multitasking, and a more responsive user interface on the G70. The additional cores allow the G70 to handle background processes more effectively, preventing slowdowns. Users who frequently switch between apps or engage in light gaming will see a noticeable benefit from the G70’s processor.
Battery Life
Battery capacity isn't specified for either device. However, given the G70’s more powerful processor, it will likely consume more power. The J6S, with its less demanding CPU, may offer slightly longer battery life on a single charge. Charging wattage is also unknown, but both are likely to support standard 5W or 10W charging, resulting in relatively slow charge times. The G70’s performance advantage may necessitate more frequent charging, but the faster processing speed could offset this by allowing users to complete tasks more quickly.
Buying Guide
Buy the BLU J6S if you need a truly minimal smartphone for basic tasks like calls, texts, and light web browsing, and your budget is extremely limited. Buy the BLU G70 if you prefer a more responsive experience for social media, streaming, and occasional gaming, and are willing to spend a bit more for improved performance.
Frequently Asked Questions
❓ Will the BLU G70 be able to run popular social media apps like TikTok and Instagram smoothly?
Yes, the BLU G70’s octa-core processor and Cortex-A53 architecture are sufficient to run social media apps like TikTok and Instagram without significant lag.

❓ Is the BLU J6S suitable for someone who primarily uses their phone for calls and texts?
Absolutely. The BLU J6S is perfectly adequate for basic communication tasks like making calls and sending texts. Its quad-core processor is sufficient for these functions, and its lower price point makes it an attractive option for users with minimal smartphone needs.
❓ Can the BLU G70 handle basic mobile games like Candy Crush or Subway Surfers?
Yes, the BLU G70 should handle casual mobile games like Candy Crush and Subway Surfers without issue. However, don’t expect to play graphically intensive games at high settings. The processor is capable, but it’s not a gaming powerhouse.
❓ What type of storage does each phone use, and is it expandable?
Storage type and expandability are not specified. However, given the price point, both likely feature eMMC storage. Expandability via microSD card is common in this segment, but it's not guaranteed. Check the product listing for confirmation.
