Q: Are there any tips for improving GPS performance on the golf course?
A: Try setting your auto-lock setting to "never".
Run the settings application (not FreeCaddie), then go to General and select "Auto-Lock".
Setting the value to never will keep your iPhone's GPS running and your position will be monitored continously.
Q: Any tips for extending battery life?
A: Disable Bluetooth, 3G (if not using maps), and turn down the brightness.
