Backup Battery

[forvisor]

I have a quick question about the HTC Titan and yes I have searched and couldn’t find anything.

Does this phone have a backup battery? This is my second or third windows mobile device, my first pda phone. All of the other devices I’ve had have had a backup battery that allowed for 30min of time when the main battery goes dead. It was not user accessible, but I always found that it was a good safety net when I let the battery run too low.

Thanks all!
