Back Market Japan Inc. (Headquarters: Shibuya-ku, Tokyo, hereinafter referred to as Back Market), one of the world's largest marketplaces specializing in refurbished electronics, announced today that it has revamped its grade and battery quality standards for refurbished smartphones, including iPhones. These revised standards are unique to the Japanese market and are not deployed in other countries. Refurbished products are pre-owned electronic devices that have been collected, inspected, cleaned, and repaired by professionals, ensuring all functions operate correctly.

A survey conducted by Back Market with 1,000 participants revealed that 'when the battery life started to degrade' (69%) was the top reason for smartphone replacement. The survey also showed a strong tendency to prioritize 'price' (61.1%) and 'battery life' (52.8%) when purchasing a new device. To ensure transparency in the customer purchasing experience, Back Market has expanded its battery capacity criteria from the previous single category of '80% or more' for grades A to C, to three distinct options: '80-89%', '90-99%', and '100% (new battery)'. This allows customers to understand the battery's condition in more detail before purchasing.

Furthermore, for the premium grade, the battery capacity standard has been changed from '90% or more' to '100%', and all components will be manufacturer-genuine. The premium grade also features enhanced post-purchase support, with battery returns, repairs, or replacements handled under the following conditions:

Within 30 days: Return or exchange if the maximum battery capacity drops below 98%.

Within 1 year: Repair or exchange if the maximum battery capacity drops below 90%.

The company also strives to maintain high quality levels through anonymous quality checks (mystery orders) and continuous monitoring of customer reviews.
