On SW 2.5 I went from 3-4 days with activities using HR & GPS to a full drain from 100% down to flat lined in 18 hours with no activity. Reading other forums on the vivoactive3 (non music) there was a battery drain issue in V2.5 resolved in 2.6.
I saw on 4/4/18 SW 2.7 was available. Recieved it 4/5/18. Doing a full power cycle I'm currently tracking about 10% per hour with no activity tracking or GPS. SW 2.7 doesn't appear to be a battery drain fix.
I've removed all watch faces except the active (VSWF) and haven't loaded any music on yet.
Looking to hear of others results and possible solutions.
