These battery life predictions for your RockSTAR assume the following:
• No display usage
• Bluetooth set to off
• GPS early-wake set to 20 seconds
• 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/poor view of the sky
- Use of the device with the display on for long periods of time
Transmissions per day
Every 1 minute
Every 5 minutes
Every 15 minutes
Every 30 minutes
Every 1 hour
Every 4 hours
Diminishing returns on power savings due to electrical impedance.
There is very little power saving benefit from transmitting less frequently than every 4-6 hours.
The principal benefit of slower transmission rates is in the lower data cost.
The battery in your device should maintain its ability to charge to at least 90% of capacity through 1000 charge cycles. This means that if you charged the unit every day (unlikely) the battery would need to be replaced every 3 years. If you charged the device once a week, it would need the battery replacing once every 10 years.
Realistically, you do not need to worry about replacing the battery - but keep in mind it's not user-replaceable; it can only be replaced by your device service provider.
