Venu3 empty battery after 2 days since update to 13.17

Hello,

since the last software update 13.17 my Venu 3 does not last more than 2 days.

Battery consumption is 1.9% per hour all of a sudden.

And then it suddenly dies after 1.5 day or so.

I have done a hard reset already, but that did not help. Also reset to factory settings. That did not help either.

Is there anything else I can try to get this solved?

Cheers

Richard Verbeek.
