Hi,
Not a Juice Defender user, so maybe my comments will be off-base, but let me try:
- "Settle in delay" depends on JD and your device, basically, how long AquaMail should wait to the WiFi connection to fully kick in (become usable). On my devices, I typically see around 10-15 seconds, but I suppose some devices or routers could take longer.
You could try a longer setting, or even before you do that, you could run a test with the screen on, and see if AquaMail's "blue @" icon shows in the status bar after WiFi is turned on, indicating it's trying to sync.
- "Minimum interval" is up to you -- someone could have JD turn on WiFi every 15 minutes, and wanted for AquaMail to only sync once an hour -- while someone else might want a different schedule.
Did you know that if you set your system settings to disable WiFi when the device's screen is off (the default since Andorid 2.3 is to always keep it on, but there is a system setting to change it, no third party app needed) -- then AquaMail will enable WiFi, wait for it to connect, then let it turn off again?
