Hi still having the same problem as before.

When setting the 'Internet connections'
automatic connection to any interval the battery drains.
seems like something is hanging when searching networks and drains immensely. (4 to 6 hours on 1 charge)

I always have it set to 'always ask/manual' and the problem is solved so I can normally work with the device for 2 days with a single charge.

The device is great, as long as I set the internet connection manually.
and (for me) really there is no reason why NOT to do it anyway, so for me its not a real problem :-)
