Quality declaration for battery
The capacity of your mobile phone battery reduces each time you charge/ discharge it. Storing the battery at temperatures that are too high or too low also causes a gradual loss of capacity. This can cause the operating times of your mobile phone to reduce significantly per usage cycle.
The battery is, however, designed to be charged and fully discharged within a period of six months from when the mobile phone was pur- chased. Following this six months period, we recommend replacing your battery if you experience a significant drop in performance. Please purchase only Siemens original bat- teries.
