thanks for the replies :-)

OK how about this, (I'm referring to an old fossil of a tomtom one 25) there used to be a feature in the tomtom home app that allowed me to enable or disable the use of quick fix.... this changed a while back and the menu is not there to stop using the feature... so its ON and now no ability to say OFF anymore.

This device has always been flat (as was the one I got for my parents) and the battery always struggles.... then I saw why.... rather than the quick fix being a weekly file informing the device where to look when I needed it, I see what it really does…. if you keep it charged up, it likes to turn itself on randomly and waits till it gets sat lock. if its in a place where it can't see satellites it just runs till the battery is flat... so when you really need it, it needs 3 hours on charge before you turn it on, or its boot often gets very muddled and delayed and you can have a hell of a fight. Keep on top of why its going flat always behaves perfectly.

This behaviour is something I noticed its does at least once a week after the quick fix menu in tomtom home vanished some years ago... but it probably always did it, just like my parents version of the same device.

Any thought on that one....? my tomtom bike one is normal if I turn that off its OFF
