Snapdragon 4s Gen 2 vs Helio G35: Speed & Battery

The Snapdragon 4s Gen 2 is significantly faster and more power-efficient than the MediaTek Helio G35, making it the better choice for everyday speed and battery life. The Helio G35, while older and slower, is still found in budget phones and can handle basic tasks, but it lags in gaming, multitasking, and sustained performance.

Background: Two Chips from Different Eras

The Snapdragon 4s Gen 2 (SM4635) is a budget 5G chip announced in July 2024, built on a modern 4nm process. It replaces the older Snapdragon 4 Gen 1 and targets affordable 5G phones. The Helio G35, in contrast, launched in mid-2020 on a 12nm process and was designed for entry-level 4G phones. That three-year gap in process technology (4nm vs 12nm) is the single biggest factor behind the differences in speed and battery efficiency.

Process nodes matter because a smaller number means denser, more efficient transistors. The 4nm Snapdragon can do more work per watt of electricity than the 12nm Helio, which directly translates to better battery life under load and less heat generation.

CPU and GPU Performance: Real-World Speed

The Snapdragon 4s Gen 2 uses an octa-core CPU with two Cortex-A78 performance cores (up to 2.0 GHz) and six Cortex-A55 efficiency cores. The Helio G35 also has eight cores, but all are older Cortex-A53 cores running at up to 2.3 GHz. While the Helio has a higher clock speed, the A78 architecture is vastly more efficient per clock cycle—roughly 40-50% faster than the A53 in single-thread tasks. In practical terms, the Snapdragon opens apps faster, scrolls more smoothly, and handles heavier web pages without stuttering.

For graphics, the Snapdragon 4s Gen 2 includes an Adreno GPU (likely Adreno 613), while the Helio G35 has a PowerVR GE8320. The Adreno is several generations newer and supports Vulkan 1.1 and OpenGL ES 3.2, enabling better game compatibility. In casual games like Subway Surfers or Among Us, both chips are fine, but in demanding titles like PUBG Mobile or Genshin Impact, the Snapdragon can maintain higher frame rates at low-to-medium settings, while the Helio G35 will struggle even at the lowest settings.

5G vs 4G: Connectivity and Battery Impact

The most obvious feature difference is 5G support. The Snapdragon 4s Gen 2 has an integrated 5G modem (sub-6 GHz), while the Helio G35 is strictly 4G LTE. This matters for future-proofing: 5G networks are expanding, and a 5G phone will remain relevant longer. However, 5G can consume more battery than 4G when the signal is weak, because the modem works harder to maintain a connection. In areas with strong 5G coverage, the Snapdragon’s efficient modem actually uses less power than a 4G modem on the Helio, thanks to the newer process. If you mostly use Wi-Fi, the difference is negligible.

Another connectivity advantage: the Snapdragon supports Wi-Fi 5 (802.11ac) and Bluetooth 5.1, while the Helio G35 only has Wi-Fi 4 (802.11n) and Bluetooth 5.0. This means faster local file transfers and better wireless headphone stability on the Snapdragon.

Battery Life: Efficiency Wins

Battery life depends heavily on the phone’s battery capacity, screen, and software, but the chip’s efficiency sets the baseline. In controlled tests (same battery size, same screen, same usage), the Snapdragon 4s Gen 2 typically delivers 15-25% longer battery life than the Helio G35 for mixed usage. For example, a phone with a 5000 mAh battery and a Snapdragon 4s Gen 2 might easily last two full days of light use, while the same phone with a Helio G35 would likely need a charge by the end of the second day. Under heavy gaming, the Snapdragon also runs cooler, which reduces thermal throttling and keeps performance more consistent.

Charging speed is another factor: the Snapdragon 4s Gen 2 supports Qualcomm Quick Charge 4+ (up to 18W), while the Helio G35 supports only standard 10W charging via MediaTek Pump Express. Phones with the Snapdragon will charge faster if the manufacturer includes a compatible charger.

How to Choose: What Matters to You?

• Budget: Helio G35 phones are usually $50-100 cheaper than Snapdragon 4s Gen 2 phones. If you only use your phone for calls, texts, and light web browsing, the Helio is adequate.
• Gaming: If you play any 3D games, choose the Snapdragon. The Helio G35 will frustrate you with low frame rates and frequent stutters.
• Battery life: The Snapdragon is clearly better for all-day battery, especially if you’re a heavy user.
• 5G needs: If you plan to keep the phone for 2+ years, 5G is worth having. The Helio G35 is 4G-only.
• Software updates: Newer chips typically receive Android updates for longer. The Snapdragon 4s Gen 2 will likely get 2-3 years of OS updates, while the Helio G35 is already past its support window.

Common Problems and Misconceptions

A common misconception is that the Helio G35’s higher clock speed (2.3 GHz) makes it faster. Clock speed is only one factor; architecture matters more. The A53 cores in the Helio are ancient (from 2014) and are simply outclassed by the A78 cores in the Snapdragon, even at lower clocks.

Another issue: many budget phones with the Helio G35 ship with only 2-3 GB of RAM, which causes apps to reload constantly. The Snapdragon 4s Gen 2 is often paired with 4-6 GB, making multitasking smoother. Also, some Helio G35 phones have poor thermal design, causing the chip to throttle after 10 minutes of gaming, further reducing performance.

One real problem with the Snapdragon 4s Gen 2 is that it lacks support for 4K video recording and only supports 1080p at 60fps, which is fine for budget phones but a limitation if you want high-res video. The Helio G35 also maxes out at 1080p, so no advantage there.

Alternatives to Consider

If you’re choosing between these two, you might also consider the Snapdragon 680 (a solid 4G chip with similar performance to the 4s Gen 2 but without 5G) or the MediaTek Helio G85 (a slightly faster version of the G35 with better GPU). However, the Snapdragon 4s Gen 2 remains the better overall value for speed and battery, especially if 5G is important to you.

For ultra-budget buyers, the Helio G35 is still acceptable for basic use, but expect to replace the phone sooner due to lack of updates and slower performance over time.

Frequently Asked Questions

Is the Snapdragon 4s Gen 2 good for gaming?

Yes, for a budget chip. It can handle most popular games at low-to-medium settings with stable frame rates. Heavy games like Genshin Impact will run at 30fps or lower, but it’s playable. The Helio G35 is not recommended for gaming beyond casual titles.

Which chip has better battery life?

The Snapdragon 4s Gen 2, thanks to its 4nm process and more efficient cores. Expect 15-25% longer battery life in real-world usage compared to the Helio G35 with the same battery size.

Does the Helio G35 support 5G?

No, the Helio G35 is a 4G LTE-only chip. Only the Snapdragon 4s Gen 2 supports 5G (sub-6 GHz) in this comparison.

Can I use a Helio G35 phone for video calls and social media?

Yes, for basic video calls (WhatsApp, Zoom) and social media scrolling, the Helio G35 is fine. It may struggle with heavy multitasking or editing videos, but it handles standard apps adequately.

Is the Snapdragon 4s Gen 2 worth the extra money?

If you can afford the price difference (usually $50-100), yes. You get better performance, longer battery life, 5G, and more future-proofing. If you’re on a strict budget and only need a basic phone, the Helio G35 is still a viable option.

Final Verdict

In the Snapdragon 4s Gen 2 vs Helio G35 battle, the Snapdragon wins decisively on speed, battery efficiency, and connectivity. The Helio G35 is an older, budget chip that’s best for basic tasks. If you want a phone that will last longer and perform better, choose the Snapdragon 4s Gen 2. If you’re extremely budget-constrained and don’t game or use heavy apps, the Helio G35 will do the job, but be prepared for slower performance and shorter software support.
