Comparing Battery Life: Samsung, Google, and OnePlus

In the quest to determine which Android phone triumphs in battery endurance, we tested top models from Samsung, Google, and OnePlus. The results were indeed eye-opening.

Understanding Battery Life

Battery performance can be a complex topic. A larger mAh rating doesn't automatically ensure longer usage times. Using a phone for varied tasks significantly impacts its power consumption. For example, a device playing locally stored content tends to last longer than one processing intensive tasks like exporting videos.

Screen technology and system processor significantly influence power usage. AMOLED displays, as opposed to standard LED panels, present nuances in power draw. Therefore, many aspects must be considered when evaluating battery life.

Evaluating OnePlus's Bold Claim

When OnePlus introduced a phone boasting a 7,400mAh battery, claiming it was the largest available in the U.S., we were intrigued. To assess its stamina, we devised two tests: a continuous 4K video playback and a battery endurance evaluation using PC Mark.

Methodology of the Test

For our testing, we selected top U.S. models from Samsung, Google, and OnePlus, excluding Apple and Motorola due to unavailability. We subjected these phones to the Work 3.0 Battery Rundown via PCMark, which simulates everyday activities until battery level declines to 20%.

Our video test, inspired by YouTube experts, involved playing a 4K movie loop through VLC. All phones were placed in Airplane mode, with Wi-Fi and Bluetooth off, set at maximum screen brightness, and 25% volume. We meticulously recorded the shutdown times with cameras.

Results from the Tests

Video Playback Outcome

In our video test, Google’s Pixel 10 Pro XL, equipped with a 5,200mAh battery, was the first to power down after less than 20 hours. Subsequently, the Samsung Galaxy S25 Ultra with a 5,000mAh battery gave out, surviving a bit over 25 hours. Interestingly, the OnePlus 15R and OnePlus 15 lasted longer, despite the 15 boasting a slightly smaller battery but with superior efficiency due to its processor.

PCMark Testing Findings

Our processor-heavy PCMark test revealed the OnePlus 15R and Samsung models expiring first. The Pixel 10 Pro XL, notable for its energy-focused processor, endured longer, but OnePlus 15 topped it at over 13 hours, attributing to its advanced chip design.

Key Insights

This analysis underscores that myriad factors contribute to phone stamina. It's the synergy between battery size, display technology, and processing power that paints the true picture of endurance. Bigger isn't always better, and like smartphone cameras and processors, effective performance depends on the blend of attributes.
