@maccatori Can you please first try a factory reset and check if the battery lasts after updating to 1.7.64?In most cases this fixes the issues without a need to downgrade to an older firmware. Let us know!
[user=93]Jürgen[/user] or @lampard - I can't find your kind reply in this thread to reference it - I have done the factory reset as suggested and it has put me on 1.7.64 however I thought you were going to put me on an earlier version. Battery life still cutting after 10mins GPS (I'm not using the phone alerts feature at all). Many thanks in anticipation.
