Battery protection
•
Frequently charging a battery under high voltage may shorten
the battery life. To protect the battery, once the battery is fully
charged, the system may stop charging when the battery
power is between 90% and 100%.
NOTE: The level at which the battery resumes charging is usually set
between 90% and 99%. The actual value may vary by model.
•
Charging or storing a battery in high ambient temperatures
may result in permanent damage to the battery power
capacity and rapidly shorten battery life. If the battery
temperature is too high, the system may reduce the battery
power charging capacity or even stop charging to protect the
battery.
•
Battery power capacity may drop even when your device is
powered off and disconnected from the AC power. This is
normal as the system still draws a small amount of power
from the battery.
