How to make your battery last longer
•
Make sure you follow the complete charge time (minimum 2.5 hours).
•
After a partial charge, the battery level indicator may not be exact. Wait
for at least 20 minutes after removing the charger to obtain an exact
indication.
•
Adjust the brightness of screen as appropriate.
•
Extend the email auto-check interval for as long as possible.
•
Update news and weather information on manual demand, or increase
their auto-check interval.
•
Exit background-running applications if they are not being used for a
long time.
•
Deactivate Bluetooth, Wi-Fi, or GPS when not in use.
The phone will become warm following prolonged calls, game
playing, internet surfing or running other complex applications.
•
This heating is a normal consequence of the CPU handling excessive
data. Ending above actions will make your phone return to normal
temperatures.
