Double check that the activity and satellite settings are still the same after the update.

WOW! I wish mine was like that! Mine was worse since day 1 (2.5 years ago). I never reached 6 days. You also have some 4 big activities there. It's not bad at all! What was your battery usage like before…

Statistically the newer version will be even worse :( It's worth to wait and see what others report.

For 27.10 it looks like all they did was to roll back some of the sensor versions. Not sure why they haven't done the same for the other models as users experienced similar issues.

Save old firmware files so you can roll back.

Yes, few outdoor runs nothing major its already raining for 2 months in ireland. But definitely not 4 times faster but at least twice than before

What is aprox duration of those runs ?

One run exactly an hour, and 3-4 run under 45 min with GPS use, i do use the watch for indoor cycling and indoor running but with no GPS.
