I 13 Troubleshooting
• 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 .
