Solution
• Are you in an area of variable coverage? This
uses extra battery power.
• Is your antenna fully extended and correctly
angled? Do you have a clear unobstructed
view of the sky? This helps use less battery
power.
• Is it a new battery? A new battery needs two
to three charge/discharge cycles to attain
normal performance.
• Is it an old battery? Battery performance
declines after several years of use. Replace
the battery.
• Is it a battery that hasn't been completely
discharged? Allow the battery to fully
discharge (until the phone turns itself off)
and then charge the battery overnight.
• Are you using your phone in extreme
temperatures? At extreme hot or cold
temperatures, battery performance is
significantly reduced.
You may notice this during long calls or
during charging. The heat is produced by the
electronic components within your phone and
is quite normal.
Remove the battery from the phone and then
reattach it to cycle power and reset.
