Recharging in the mobile takes longer and the standby time will be halved. The short standby time and recharging error may be caused by faulty firmware or a faulty 3G network. In addition the battery time can be increased by turning off the GPS and vibra call alert, and by turning down the backlight of the display. Testing has revealed that using the phone in 2G network will provide 3-4 times the standby time than using it in 3G networks.
