Batteries are consumable components and naturally lose capacity through age, charge cycles, storage and previous use.
Unless a product listing expressly states a specific battery-health percentage, battery runtime is not guaranteed to match the performance of a newly manufactured product.
Refurbished devices are assessed to confirm that the battery powers or charges the device to an acceptable operational level at the time of testing.
Actual battery runtime will depend on factors including:
- Screen brightness
- Applications and background processes
- Network usage
- Power-management settings
- Battery age and previous charge cycles
- Device configuration and operating environment
Where a battery is described as degraded, service recommended, faulty or requiring replacement, this will form part of the disclosed product condition.
