Choosing the right smartphone can be daunting, especially with so many factors to consider. Among these, the display, camera quality, and battery life are paramount. With an increasing reliance on our devices, battery performance often becomes the deal-breaker. In a time when usage patterns take many forms, understanding battery technology is essential for every smartphone user.
After testing over 50 smartphones, including the latest ones, I’ve discovered which devices truly lead the pack in battery life. Here’s a deep dive into what I found, focusing on battery technology and performance.
Understanding Battery Technology
For years, the smartphone industry has relied on lithium-ion batteries; however, a new contender has emerged: Silicon Carbon technology. This innovative battery type offers higher energy density and faster charging capabilities. The first smartphone to feature this technology was the Honor Magic V5 Pro, and it’s quickly gaining traction among newer devices.

With so many phone releases each year, I focused my tests on two categories: traditional candybar designs and innovative folding phones. Here’s a list of the top contenders:
- Apple iPhone 16 Pro Max
- Samsung Galaxy S25 Ultra
- Samsung Galaxy S25 Edge
- Google Pixel 9 Pro XL
- OnePlus 13
- Motorola Razr 60 Ultra
- Samsung Galaxy Z Flip 6
- Samsung Galaxy Z Fold 6
- Google Pixel 9 Pro Fold
- Oppo Find N5
How Testing Was Conducted
With nearly 20 years of experience in phone reviews, I maintained consistency in my testing. All phones were reset to factory settings, ensuring a clean slate for performance measurement. I tested web browsing, video playback, and gaming to assess battery longevity. Each phone was set at 200 nits brightness to eliminate variability.
What Are the Best Phones for Web Browsing & Social Media?
