Battery Life Drain Test: S24 Ultra vs. Competitors

Test Setup and Methodology

The video presents a detailed battery drain test comparing the Samsung Galaxy S24 Ultra against its predecessor (S23 Ultra) and other flagship smartphones: OnePlus 12, Oppo Find X7 Ultra, Vivo X100 Pro, Google Pixel 8 Pro, and iPhone 15 Pro Max.

• Conditions: All phones were set to the same brightness levels (using a lux meter), had 100% battery health, were updated to the latest software, were SIM-free, connected via Wi-Fi, running at adaptive 1-120Hz refresh rates, and set to their native screen resolutions.
• Monitoring: The test monitored battery percentage, temperature (in Celsius), and elapsed time. Percentages were recorded at 30-minute intervals.
• Activities: The test included a variety of tasks: Shazam (auto mode), screen recording, selfie video recording (1080p 30fps), main video recording, and an hour of benchmark testing (AnTuTu, 3DMark, GFXBench) to simulate high-performance gaming.
• Room Temperature: The ambient temperature was maintained at approximately 22.2 degrees Celsius.

Performance Analysis

Initial Stages (0-3 Hours)

• The S24 Ultra initially showed a slight lead over the iPhone 15 Pro Max, but they soon matched each other in battery percentage.
• The Pixel 8 Pro consistently ran the hottest.
• After 2 hours 30 minutes, the OnePlus 12 and Vivo X100 Pro were leading, with the Pixel 8 Pro lagging behind.

Mid-Test (3-7 Hours)

• The iPhone 15 Pro Max and S24 Ultra remained very close in battery percentage.
• The Vivo X100 Pro's performance was surprisingly strong, considering its Dimensity 9300 chipset lacks dedicated efficiency cores.
• After 7 hours, the iPhone 15 Pro Max took a slight lead over the S24 Ultra.

Final Stages (7-10+ Hours)

• The Pixel 8 Pro was the first to die, followed by the S23 Ultra and Oppo Find X7 Ultra.
• The S24 Ultra, OnePlus 12, Vivo X100 Pro, and iPhone 15 Pro Max all lasted past the 9-hour mark.
• The S24 Ultra and OnePlus 12 died at almost the same time (9 hours 46 minutes).
• The Vivo X100 Pro lasted an impressive 10 hours 22 minutes.
• The iPhone 15 Pro Max ultimately won the test with 10 hours 40 minutes of screen-on time.

Key Findings and Observations

• S24 Ultra vs. S23 Ultra: The S24 Ultra demonstrated improved battery efficiency and thermal management compared to the S23 Ultra, thanks to the optimized Snapdragon 8 Gen 3 for Galaxy chipset. The S24 Ultra lasted almost an hour longer than its predecessor.
• iPhone 15 Pro Max Performance: Software updates significantly improved the iPhone 15 Pro Max's battery life compared to initial tests. The presenter noted, "iPhones are known to hold those last few percentages like your life is depending on it."
• Vivo X100 Pro Surprise: The Vivo X100 Pro's performance was unexpected, given its Dimensity 9300 chipset's core configuration.
• Chipset Efficiency: The Tensor G3 chip in the Pixel 8 Pro, manufactured by Samsung, appeared less efficient than the Qualcomm chips manufactured by TSMC.
• Battery Capacity Impact: The OnePlus 12 and Vivo X100 Pro, with their larger 5400 mAh batteries, performed well, but the S24 Ultra's efficiency allowed it to compete closely despite its smaller 5000 mAh battery.
• Thermal Performance: The Oppo Find X7 Ultra reached the highest peak temperature (66°C), while the iPhone 15 Pro Max remained the coolest (49.3°C).

Results Summary

1. iPhone 15 Pro Max: 10 hours 40 minutes
2. Vivo X100 Pro: 10 hours 22 minutes
3. Samsung Galaxy S24 Ultra: 9 hours 46 minutes
4. OnePlus 12: 9 hours 46 minutes
5. Oppo Find X7 Ultra: 8 hours 27 minutes
6. Samsung Galaxy S23 Ultra: 8 hours 21 minutes
7. Google Pixel 8 Pro: 8 hours 10 minutes

Comparison to Previous Tests

• The S23 Ultra's battery life had slightly decreased since the initial test 11 months prior.
• The Pixel 8 Pro's battery life remained relatively consistent.
• The iPhone 15 Pro Max's battery life significantly improved due to iOS updates, gaining almost 2 hours compared to the initial test.
• The S24 Ultra showed a substantial improvement over the S23 Ultra.
• The OnePlus 12 showed an insane improvement as opposed to the OnePlus 11.
• The Vivo X100 Pro showed a significant improvement over the X80 Pro.

Hypothetical Battery Capacity Adjustment

The presenter speculated on how the results would change if all phones had a 5000 mAh battery. The iPhone 15 Pro Max would jump to 12 hours and 1 minute. The Samsung would now place second with the same time, though it would be ahead of the OnePlus and Vivo because it has a smaller battery at 5,000 Mah hours where the others have 5,400 Mah batteries.

Conclusion

The battery drain test provided valuable insights into the battery performance of flagship smartphones. The iPhone 15 Pro Max reclaimed its top spot, benefiting from software optimizations. The S24 Ultra demonstrated improved efficiency over its predecessor. The Vivo X100 Pro was a surprise performer. The test highlighted the importance of both battery capacity and chipset efficiency in determining overall battery life. The presenter was impressed that all devices lasted over 8 hours.
