Charging And Discharging; Maximising Battery Performance - Vertu CONSTELLATION RM-389V Quick Manual

Battery
Warning: Never dispose of batteries in a fire.
Always dispose of batteries according to local regulations.
Please recycle when possible. Do not dispose of batteries as
household waste.
Important: Battery talk and standby times are estimates only and
depend on signal strength, network conditions, features used, battery
age and condition, temperatures to which battery is exposed, use in
digital mode, and many other factors. The amount of time a device is
used for calls will affect its standby time. Likewise, the amount of time
that the device is turned on and in the standby mode will affect its talk
time.
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. If you notice
that the talk and stand-by times are much shorter than normal, you may
need a new battery. Contact Vertu Customer Service (page 34) to obtain a
Vertu approved battery.

Maximising battery performance

Certain functions in your Vertu phone can be switched off if not in use, to

Charging and discharging

Unplug the charger from the AC outlet and the Micro USB connector from
your Vertu phone when not in use. Do not leave your Vertu phone
connected to a charger. The battery does not have to be completely
discharged before you can recharge it. Continuously charging the battery
may shorten its lifetime. If left unused, a fully charged battery will lose its
charge over time. Temperature extremes can affect the ability of your
battery to charge.
Use chargers indoors.
Battery care and safety
Use the battery only for its intended purpose. Never use any charger or
battery that is damaged.
Leaving the battery in hot or cold places, such as in a closed car in summer
or winter conditions, will reduce the capacity and lifetime of the battery.
