BLU offers compelling options in the ultra-budget smartphone space, but the J5L and G63 represent distinctly different approaches. The J5L prioritizes affordability, while the G63 aims to deliver a more substantial performance boost. This comparison dissects the core differences, focusing on the CPU architecture and its impact on everyday use.
🏆 Quick Verdict
For most users, the BLU G63 is the superior choice. Its octa-core processor, featuring Cortex-A75 cores, provides a significantly smoother experience for multitasking, app loading, and even light gaming. While the J5L is cheaper, the performance deficit is substantial enough to justify the price difference.

BLU J5L
- Lower price point makes it accessible to budget-conscious buyers.
- Simpler software experience may appeal to users who prefer a less cluttered interface.
- Potentially longer battery life with light usage due to less powerful processor.
- Significantly slower performance compared to the G63.
- Struggles with multitasking and demanding apps.
- Likely to exhibit noticeable lag and slowdowns.
BLU G63
- Much faster performance thanks to the octa-core processor and Cortex-A75 cores.
- Smoother multitasking and app loading.
- Better suited for light gaming and demanding applications.
- Higher price point.
- Potentially shorter battery life under heavy usage.
- May experience some thermal throttling during prolonged intensive tasks.
Display Comparison
Display specifications are not provided, so a direct comparison is impossible. However, given the price points, both devices likely utilize LCD panels with 720p+ resolution. The G63, being the higher-tier model, *may* feature slightly better color accuracy or brightness, but this is speculative. Bezels are likely to be substantial on both devices, typical of this market segment.
Camera Comparison
Camera details are absent, making a detailed comparison impossible. It's reasonable to assume both phones feature basic camera setups. Given the market segment, image quality will likely be adequate for casual snapshots but will struggle in low-light conditions. The presence of a 2MP macro camera on either device is unlikely to significantly enhance the photography experience; its resolution is too low for detailed macro shots.
Performance
The core difference lies in the CPUs. The BLU J5L’s quad-core 1.4 GHz Cortex-A53 processor is an older, less efficient architecture. The BLU G63, however, boasts an octa-core configuration with a heterogeneous setup: two 1.6 GHz Cortex-A75 cores and six 1.6 GHz Cortex-A55 cores. The A75 cores are significantly more powerful than the A53, offering a substantial performance uplift in CPU-intensive tasks. This translates to faster app launches, smoother multitasking, and improved responsiveness. The A55 cores handle background tasks efficiently, contributing to better overall power management. The G63 will demonstrably outperform the J5L in benchmarks and real-world usage.
Battery Life
Battery capacity and charging wattage are not specified. However, the more powerful processor in the G63 will likely consume more power. Therefore, battery life will depend heavily on usage patterns. The G63’s faster processing capabilities *could* offset some of the increased power draw by completing tasks more quickly, reducing screen-on time. Without specific data, it’s difficult to determine which phone offers superior battery endurance.
Buying Guide
Buy the BLU J5L if you need a basic smartphone for essential tasks like calls, texts, and light social media browsing, and your budget is extremely limited. Buy the BLU G63 if you prefer a more responsive experience, enjoy occasional gaming, or frequently switch between multiple apps. The G63’s more powerful processor will noticeably improve your daily usage.
Frequently Asked Questions
❓ Will the BLU G63 handle popular games like PUBG Mobile or Call of Duty?
The BLU G63’s octa-core processor with Cortex-A75 cores is capable of running PUBG Mobile and Call of Duty Mobile at medium settings with acceptable frame rates. However, don’t expect a flagship-level gaming experience. Frame drops may occur during intense firefights. The J5L would struggle significantly with these titles.
❓ Is the difference in performance between the J5L and G63 noticeable for everyday tasks like browsing and social media?
Yes, the difference is quite noticeable. The G63 will feel significantly snappier when opening apps, scrolling through webpages, and switching between tasks. The J5L may exhibit lag and slowdowns, especially with multiple apps open. The G63 provides a more fluid and responsive user experience.
❓ Does the BLU G63 get hot during extended use, like while gaming or watching videos?
While the G63’s processor is more powerful, it’s unlikely to experience severe overheating due to the relatively low power draw of the components. However, some warmth is expected during prolonged intensive tasks. The J5L, with its less powerful processor, will generate less heat.
