What is the average battery life of an iPhone 6s?

The average battery capacity of a new iPhone 6s is approximately 10 hours of internet browsing and 11 hours of video playback. When you purchase a refurbished iPhone the battery has likely been slightly depleted but at Frank We guarantee our batteries retain a minimum of 80% of their original capacity (which Apple has declared sufficient for efficient battery performance 🔋).

Apple's lithium-ion batteries are designed to hold at least 80% of their original capacity for a high number of charge cycles, this will vary depending on the product.
