Charging the battery
The rechargeable Li-ion battery that comes with your
phone is ready to use, but is not charged. That’s easy to do.
We’ll show you how below.
The first three times you use the battery, make sure it’s
completely drained before recharging, then recharge it
fully. That will help to ensure its optimum performance and
a long life.
