84Quality declaration for battery

The capacity of your mobile phone battery is reduced 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-month pe- riod, we recommend replacing your battery if you experience a significant drop in performance. Only purchase original Siemens batteries.
