Samsung Galaxy S25 vs. S24 vs. S23: Battery Life Comparison

The Samsung Galaxy S series has long been a benchmark for smartphone innovation, with battery life consistently ranking as a top priority for users. This comparison video from Simple Alpaca evaluates the battery performance of six Galaxy S models—spanning from the Galaxy S20 to the latest Galaxy S25—under identical conditions. The results demonstrate the evolution of battery efficiency, driven by advancements in hardware, chipset optimization, and display technology. These findings provide valuable insights into how Samsung has refined its devices to meet the demands of modern users.

Test Conditions: Making sure Fair Comparisons

To guarantee accurate and unbiased results, all six devices were tested under identical conditions. Each phone was set to maximum brightness, making sure uniform screen output. Background applications were cleared to eliminate any interference, and the same tasks—streaming YouTube videos and playing Temple Run 2—were performed simultaneously on all devices. Battery levels were monitored at regular intervals to simulate real-world usage scenarios. These controlled conditions ensure that the results reflect the true capabilities of each model’s battery.

Battery Performance: How Each Model Fared

The test results reveal a clear progression in battery performance across the Galaxy S series. Each model showcased varying levels of efficiency, with newer devices generally outperforming their predecessors. Here’s how they ranked:

• Galaxy S25: The standout performer, lasting over 9 hours with 21% battery remaining at the end of the test. This marks a significant leap in battery longevity, setting a new standard for the series.
• Galaxy S24: A close second, delivering over 9 hours of usage before shutting down. Its performance highlights steady improvements in energy efficiency.
• Galaxy S23: Achieved 7 hours and 13 minutes of usage, falling short of its successors but still offering respectable battery life for its generation.
• Galaxy S21: Slightly outperformed the S23, demonstrating better efficiency despite being an older model.
• Galaxy S22: The weakest performer, lasting approximately 6 hours. Its efficiency lagged behind even the older Galaxy S20.
• Galaxy S20: Marginally outperformed the S22 but remained among the least efficient in the lineup, reflecting the limitations of its older technology.

Key Insights and Trends

The results of this comparison reveal several important trends and insights into the evolution of battery performance within the Galaxy S series. These findings underscore the impact of technological advancements and design choices on battery efficiency:

• The Galaxy S25 emerges as the leader, benefiting from innovative hardware and chipset technology that significantly enhance energy efficiency.
• Newer models equipped with the Snapdragon chipset demonstrate superior energy management, allowing longer usage times even under demanding conditions.
• The Galaxy S22 underperformed, raising questions about potential inefficiencies in its design or software optimization compared to both its predecessor and successor.
• Advancements in display brightness management in the latest models reduce energy consumption, even when operating at maximum brightness levels.
• Incremental improvements in battery design and thermal management systems contribute to the steady progression of battery performance across the series.

Technological Advancements Driving Efficiency

The improvements in battery life across the Galaxy S series can be attributed to several key technological advancements. These innovations highlight Samsung’s commitment to enhancing user experience through better energy management:

• Battery Design: The Galaxy S25 incorporates a more efficient battery design, extending usage time without increasing the physical size of the battery.
• Chipset Optimization: The Snapdragon chipset in the S25 and S24 models optimizes energy consumption, particularly during resource-intensive tasks like gaming and video streaming.
• Hardware Enhancements: Improved thermal management and power distribution systems in newer models contribute to reduced energy wastage and better overall efficiency.
• Display Technology: Advances in display technology, including brightness optimization and adaptive refresh rates, help minimize energy drain while maintaining high-quality visuals.

Future Implications for Battery Performance

The Galaxy S25 stands out as the clear leader in this battery showdown, offering a substantial improvement in longevity compared to its predecessors. Its ability to last over 9 hours with 21% battery remaining underscores Samsung’s progress in battery technology and chipset efficiency. The Galaxy S24 also performed admirably, continuing the trend of incremental improvements that have defined the series.

For users who prioritize battery life, the Galaxy S25 represents a compelling choice, combining innovative technology with practical benefits. However, the underperformance of the Galaxy S22 serves as a reminder that not all models in a series achieve the same level of optimization. As Samsung continues to refine its devices, future iterations of the Galaxy S series are likely to push battery efficiency even further, setting new benchmarks for smartphone performance and user satisfaction.
