At Longhehui, a manufacturer specializing in smartphone batteries, smartwatch batteries, tablet batteries, and laptop batteries, we understand that modern flagship devices like the S25 FE are not just about processing power—they are a complete ecosystem where energy efficiency and battery reliability are central to user experience.

In this technical overview, we analyze the S25 FE’s hardware configuration and its impact on power consumption, offering insight into how advanced battery design supports high-performance mobile devices.

📱 Galaxy S25 FE – Key Specifications

⚙️ How High-Performance Hardware Impacts Battery Demand

The Galaxy S25 FE delivers flagship-level performance, but each advanced feature contributes to higher power consumption:

• The 10-core Exynos 2400 enables smooth multitasking and powerful gaming.

• However, high-frequency CPU/GPU usage significantly increases power draw.

• This requires a battery capable of stable high-current discharge without overheating or voltage drop.

• The high refresh rate ensures ultra-smooth scrolling and responsive touch.

• AMOLED technology saves power on dark content, but 120Hz operation still consumes 30–40% more power than 60Hz.

• Adaptive refresh helps, but video and gaming keep the screen active at peak rates.

• The 50MP main sensor with OIS and 8K video recording demands intense processing and sensor power.

• Recording 8K video can triple power consumption compared to idle mode.

• The battery must sustain high loads while maintaining thermal stability.

🔋 Battery Performance: Meeting the Demands of Modern Usage

The 4900mAh battery in the S25 FE is central to achieving its claimed 28-hour video playback. Behind this number lies a complex set of engineering requirements:

• In a slim 7.4mm body, maximizing battery capacity within limited space is critical.

• Longhehui uses high-density NMC (Nickel Manganese Cobalt) cells and optimized packaging to deliver more energy in standard form factors.

• Rated for 2000 charge cycles (≥80% capacity retention), the battery exceeds typical industry standards.

• This longevity requires stable electrode materials and electrolyte formulations.

• At Longhehui, we ensure long life through rigorous cycle testing, thermal-resistant separators, and advanced BMS integration.

• The S25 FE likely supports 25W+ fast charging, demanding excellent heat dissipation and charge control.

• Our batteries are designed with low internal resistance and undergo full safety testing (overcharge, short circuit, drop, high temperature) to ensure safe, reliable performance.

• The S25 FE’s Class B energy efficiency reflects intelligent software-hardware coordination.

• The battery must support adaptive power saving, real-time health monitoring, and seamless communication with the device’s mainboard.

• Longhehui batteries support I²C communication protocols for accurate voltage, temperature, and capacity reporting.

The Galaxy S25 FE exemplifies a trend: as devices get smarter and faster, the battery becomes a core system—not just a replaceable part.
