CHAPTER
• As with any mobile phone, if your phone
is turned on while you are in an area
with no wireless coverage, your
smartphone continues to search for a
signal, and that consumes power. If you
cannot move to an area with better
coverage, temporarily turn off your
phone (see Turning your smartphone
on/off).
• Turn down the screen brightness
(see A
djusting the brightness).
• Set your screen to turn off automatically
after a shorter period of inactivity (see
V
iewing and optimizing power settings).
• Keep your battery away from direct
sunlight and other sources of heat.
Temperatures over 120 degrees
Farenheit (50 degrees Celsius) can
permanently reduce the capacity and
life span of any lithium-ion battery.
• Limit use of Microsoft

Voice Command
software when it is not needed.
