Battery care and maintenance
Your Toshiba phone is powered by a rechargeable
Lithium ion (Li-ion) battery.
The full performance of a new battery is achieved
only after two or three complete charge and
discharge cycles.
The battery can be charged and discharged
hundreds of times, but it will eventually wear out.
When the talk and standby times are noticeably
shorter than normal, it is recommended that you buy
a new battery.
• A new battery, or one that has not been used for a
long time, could have reduced capacity during
initial use.
• Do not leave the battery connected to the charger
and power source for longer than necessary. This
will result in repeated short charging, which will
reduce battery performance and lifespan. Please
disconnect the AC charger when the battery is
full.
• Do not leave the battery in areas of extreme cold
or heat. This could affect the performance of the
battery.
• The battery has optimum performance in an
ambient temperature of between +5 °C (+41 °F)
and +35 °C (+95 °F).
• Only remove the battery with the phone switched
off.
• Do not leave the battery empty or disconnected
for a long time, as this may cause data to be reset.
• If you are not going to use your phone for a long
time, fully charge the battery, then switch off the
phone. The phone should be stored in a dry place
away from direct sunlight. Recharge the phone
approximately every six months.
• Avoid repeated short charging. It is preferable to
let the battery go flat and then recharge it
completely.
