Factors that Influence Estimations
Please be aware that these are estimations, and can be influenced heavily by factors such as:
-
Application and configuration: The battery life is dependent on the update rate and other settings
-
GPS reception: If GPS reception is poor, the device has to work harder, and keep its GPS module on for longer to get a fix - or it may time out and fail to get a fix, draining additional battery.
-
SIM Card Selection: Some Roaming SIM cards can trigger lengthy network scans, using up a lot of extra energy, see Roaming SIM Cards - Battery Life Impact
-
GSM Reception: As for the GPS, the same applies to the cellular modem attempting to connect to the network
-
Mounting position: This will impact GPS and GSM reception
-
Battery type and chemistry: Different batteries are of different quality and capacity
- Temperature: Extreme temperatures reduce the lifetime of most battery types.
