Real-World Battery Performance: Galaxy S24 Ultra vs. S23 Ultra vs. S22 Ultra

Here’s how the Galaxy S24 Ultra compares to the S23 Ultra and S22 Ultra in a controlled streaming test (QHD resolution, 120Hz refresh rate):

Device	After 1 Hour	After 2 Hours	After 3 Hours
Samsung Galaxy S24 Ultra	97%	91%	86%
Samsung Galaxy S23 Ultra	95%	88%	81%
Samsung Galaxy S22 Ultra	93%	86%	78%

What This Means for You:

• Improved Battery Life: The Galaxy S24 Ultra outperforms both the S23 Ultra and S22 Ultra in terms of battery retention during streaming, making it the top choice for those who prioritize long-lasting power.
• Optimized Efficiency: Thanks to innovations like stacked cell technology and the Snapdragon 8 Gen 3 chip, the S24 Ultra offers better power efficiency, allowing for a more enjoyable streaming experience without worrying about frequent recharges.

Charging Speeds and Efficiency

Charging speed is a crucial factor for today’s smartphone users, and the Galaxy S24 series offers solid performance, but there are some important details to note.

Here’s how the S24 series performs in terms of fast charging:

• Base Model: The Galaxy S24 supports 25W fast charging, which can charge the phone from 0% to 51% in just 30 minutes. This is an improvement over many older models, offering a decent speed for everyday users.
• Plus and Ultra Models: Both the S24 Plus and S24 Ultra support 45W fast charging, allowing them to charge from 0% to 50% in 30 minutes. This faster speed is ideal for power users who need a quick boost, especially for larger batteries.

What Does This Mean for You:

• Reliable Charging Speed: While the charging speeds for the Galaxy S24 series are impressive, especially for the Ultra and Plus models, they’re not groundbreaking. 45W charging for the larger models ensures you get a significant charge in a short amount of time, making it a solid option for users who are often on the go.

Limitations: Despite these improvements, Samsung has not yet introduced faster charging technology for its larger batteries, which could leave power users wanting more. With phones featuring larger capacities, many users may expect even faster charging speeds to match the increasing battery demands

Efficiency and Battery Management

Even without ultra-fast charging, Samsung’s efficient battery management system ensures you get optimal performance. The Snapdragon 8 Gen 3 chip and the stacked cell technology contribute to power efficiency, balancing fast charging with long-lasting S24 battery life. This means that while the charging speed might not set records, the combination of fast charging and energy-efficient components helps maintain the overall experience.

Comparisons with Older Models

Galaxy S24 vs. Galaxy S23

• Battery Capacity: The S24 series sees a 100–200 mAh increase in battery capacity for the base model and S24 Plus compared to the S23 models. While this may seem like a modest increase, it contributes to better overall endurance, especially when combined with efficiency improvements.
• Performance Boost: The Snapdragon 8 Gen 3 chip and enhanced software optimizations in the S24 provide significant improvements in real-world performance. Users will notice smoother multitasking, better power efficiency, and an overall more responsive experience.

Galaxy S24 vs. Galaxy S21

• Battery Capacity: The Galaxy S24 base model comes with a 4,000 mAh battery, which matches the S21’s capacity. However, the S24 benefits from modern efficiency gains thanks to improvements in both hardware and software. This allows the S24 to last longer throughout the day, despite having the same battery size.
• Stacked Cell Technology: The S24 Ultra has a clear edge over the S21 Ultra due to its use of stacked cell technology. This innovation allows for higher energy density without increasing the physical size of the battery, providing better performance and longer-lasting power compared to the S21 Ultra.

Strengths and Limitations of the Galaxy S24 Series

Strengths

• All-Day S24 Battery Life: The Galaxy S24 series offers reliable all-day battery life. With incremental capacity upgrades and efficient processors, paired with software enhancements, the S24 models provide better endurance than their predecessors. Users can enjoy uninterrupted usage throughout the day without frequent charging.
• Innovative Technology: The stacked cell technology is a standout feature in the S24 Ultra. This technology increases energy density by compressing battery components without taking up extra space. The result? Higher battery capacity and better performance, all without enlarging the device itself.

Limitations

• Charging Speed: While the S24 series offers 25W and 45W fast charging, there’s no major improvement in charging technology. This might be a letdown for power users who are looking for even faster charging times, especially with larger batteries that could benefit from quicker power-ups.
• Battery Size Trade-Offs: Larger batteries are great for longer-lasting power, but they come with their own trade-offs. Larger batteries may require longer charging times, which can affect convenience for users who need to quickly recharge during busy days.

Conclusion

Samsung’s Galaxy S24 series marks a significant step forward in battery technology. While the improvements in capacity might seem modest, the combination of stacked cell technology and Snapdragon 8 Gen 3 efficiency ensures better real-world performance. For users upgrading from older models like the S21, the S24 series offers a compelling mix of modern features, extended S24 battery life, and software longevity.
