The Battle for Smartphone Battery Life in 2026
This year has been a pivotal one in the smartphone industry, especially regarding battery technology. With a significant rise in the adoption of Si/C (silicon-carbon) batteries, manufacturers have pushed the boundaries of what’s possible, effectively integrating capacities over 7,000 mAh into regular smartphones. This advancement makes a substantial difference in user experience and device longevity.
Record-Breaking Battery Life
Our all-time battery life ranking now features models predominantly released this year, marking a notable shift in the market. Aside from the iPhone 16 Plus, the top contenders hail from 2025, showcasing impressive efficiency and performance. Some smartphones have even exceeded the 20-hour mark in active use scores, defining a new standard for battery performance.
The frontrunner, the OnePlus 15, boasts an exceptional active use score of 23:07h, followed closely by the Oppo Find X9 Pro and the iQOO 15, which secure the second and third spots, respectively.
A Shift Toward Premium Flagships
An intriguing trend emerged: nearly all smartphones on our battery life list are flagship models. This aligns with the fact that Si/C batteries, despite their benefits, are currently priced at a premium, limiting their use in more budget-friendly options.
While the Honor Magic8 Lite and iPhone 17 Pro Max did not secure a spot in the top 10 all-time list, they still made an impressive entrance, sharing the 10th position in 2025.
