Over the last three weeks my N900 (PR1.2) has been constantly using the HSPA connection whenever there is no wifi connection. This runs the battery flat in about 2 - 3 hours.

I normally have MfE running at 15 minute intervals, but even when I set this to manual the is no change in the N900 hammering the HSPA connection.

Even with no VoIP or Skype running and the browser is closed, the HSPA connection is still active. The only only other application that I can think that uses the internet is gPodder and closing that makes no difference.

The strange thing is that the battery life is normal when on a wifi connection.

I tried uninstalling most applications, but this made no difference.

I reflashed with PR1.2, restored my data and installed only a few applications, but again no improvement.

Unless anyone else has a better idea, the only option I can see is to reflash without restoring my back up and only putting in the settings for the HSPA internet connection. (Obviously this is a pain as I can't use the N900 properly while in this testing mode).
