  The NEC e616 mobile phone is a handheld 3G phone from NEC Corporation.
  
  ## Rechargeable battery
  
  The e616 takes Lithium ion batteries, which are available in different capacities:
  
  * 780 mA·h standard battery (always included) tested standby time in 3G network : 6–12 h depending on use of the phone
  * 1360 mA·h high capacity battery (sometimes included) tested standby time in 3G network : 12–24 h depending on use of the phone
  
  ## Usage notes
  
  Batteries should always be recharged in the recharger and not within the mobile phone. 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.
