Charging guidelines
Observe the following guidelines when you charge your handset:
Charge the battery for at least 6 hours before you use the handset
for the first time.
Do not leave the handset connected to the charger for more than a
month without using it.
You can charge and discharge the batteries hundreds of times, but
eventually they wear out. If the operating time (talk and standby
time) becomes significantly shorter than usual, replace the
batteries.
Extreme temperatures influence the charging capability of the
batteries.
Charging and operating times
Discharged batteries require no more than 8 hours (I755: 10 hours) to
completely recharge. Completely charged batteries provide the handset
with up to 12 hours of talk time (I755: 10 hours) and 120 hours of
standby time.
