Overview of Battery Life Testing Results
Recent tests conducted by CNET evaluated the battery life of 35 smartphones, revealing that the Apple iPhone 17 Pro Max achieved the highest performance. The tests included a three-hour video streaming assessment and a 45-minute endurance test involving various activities such as gaming and social media usage. Despite having a battery capacity of 5,088 mAh, the iPhone 17 Pro Max outperformed competitors with larger batteries, showcasing the efficiency of Apple's A19 Pro chip and iOS 26.
Top Performers in Battery Life
The iPhone 17 Pro Max was followed closely by the base model iPhone 17 and the OnePlus 15, both of which secured second place. The OnePlus 15 features a significantly larger battery capacity of 7,300 mAh, yet the iPhone 17's optimized software allowed it to match the OnePlus model's battery life. Other notable mentions in the top five include the iPhone 17 Pro, which ranked fourth, and a tie for fifth place among the Motorola Moto G Stylus (2025), Motorola Edge (2025), OnePlus 13R, and OnePlus 15R.
Brand Rankings and Insights
CNET's analysis indicated that Apple and OnePlus were the leading brands in terms of battery life, with Apple scoring an average of 91.7% across its models. Motorola and Samsung followed, with Motorola slightly ahead in overall performance. Notably, Oppo's models were excluded from brand rankings due to a lack of sufficient testing in the U.S. market, despite their strong performance abroad.
Factors Influencing Battery Life
Battery life is influenced by several factors, including the efficiency of the software, processor, and the phone's usage patterns. CNET's testing methodology aimed to standardize these variables to provide a clear comparison of battery performance across different models. The introduction of silicon-carbon batteries has been noted as a significant advancement, allowing manufacturers to increase battery capacity without enlarging the physical battery size.
Consumer Preferences and Market Trends
A CNET/YouGov survey from September 2025 highlighted that consumers prioritize battery life as a key factor when purchasing smartphones, second only to price. Despite the advancements in battery technology, the average improvement in battery life from 2024 to 2025 was minimal, at just 0.78%. This suggests that while new models may offer slight enhancements, many consumers may find older models sufficient for their needs.
Criticism and Future Considerations
While Apple and OnePlus dominate the current rankings, there are concerns regarding the longevity of silicon-carbon batteries, which may degrade faster than traditional batteries. As manufacturers continue to innovate, the performance of brands like Samsung and Motorola will be closely monitored in the upcoming years.
