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 purchased. Following this six-
month period we recommend replacing
your battery if you experience a significant
drop in performance. Please purchase only
Siemens original batteries.
