Battery Life Expectations

Battery Life Expectations
!
These battery life predictions assume the following:
!
• No display usage
• Bluetooth off
• GPS Early-wake set to 20s
• Clear sky conditions
!
!
As with all portable battery powered devices, battery life can be significantly shortened by extreme
temperatures and some usage patterns. Key factors which will shorten the number of transmissions
possible on a battery charge are:
!
• Use of Bluetooth facilities
• Use of GPS Hot Mode and Burst Mode
• Poor positioning, so poor view of the sky (most likely!)
• Use of the device with the display on for long periods of time
