Memory effect, also known as lazy battery effect or battery memory, is an effect observed in nickel cadmium rechargeable batteries that causes them to hold less charge. It describes one very specific situation in which certain NiCd batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. The battery appears to "remember" the smaller capacity. [1] The source of the effect is changes of the characteristics of the underused active materials of the cell.[ citation needed] The term is commonly misapplied to almost any case in which a battery appears to hold less charge than was expected. These cases are more likely due to battery age and use, leading to irreversible changes in the cells due to internal short-circuits, loss of electrolyte, or reversal of cells. |
Thank you for the wikipedia definition. I understand chemical difference between the Ni-cad and Li-On. The issue that I can trying to get a handle on is getting a threshold which will provide a good indicator of battery utilization.
The purpose of a conditioning phase is the define a differential in voltage change from one instance to another. Based on that, the phone can somewhat accurately predict the availible time that a battery will last giving delta-x usage. In order to do that, the battery must be completely discharged and then completely charge in order to define x.
