The Solid Technical Support team is often being approached with reports of mobile handheld devices periodically shutting down, rebooting themselves and on rare occasions losing data from the device. We have learned that although we would like to think that rechargeable batteries will last forever, this is not reality and often poor or failing batteries can be attributed to erratic performance on mobile devices.

The life of your battery will vary depending on the product configuration, product model, applications loaded on the product, power management settings of the product, and the product features used by the customer. As with all batteries, the maximum capacity of your battery will decrease with time or use.

All rechargeable batteries gradually lose their capacity to hold a charge. The battery cycle life is the total number of charge cycles a battery supplies before it can no longer hold a useful amount of charge.

This loss in capacity (ageing) is irreversible and cannot be restored. Gradually, less and less active material is available within each cell to electro-chemically store a charge. Consequently, the battery provides less usable time to power the computer.
Battery Life Cycle

Lithium-ion (Li-ion) batteries typically have a lifespan of between 300 and 500 cycles. With moderate use, Lithium-ion batteries can be expected to deliver around 80% of their original capacity after 300 cycles or about one year of use (see graph above).

Note: The graph above illustrates 80% of original capacity after 300 cycles at an operating temperature between 77°F and 104°F (25°C and 40°C). Higher operating temperatures can result in a 70% or more loss of capacity given the same number of cycles.
