Hello I bought a brand new forerunner 255s (no music) yesterday. Software version 9.15 which is most up to date it says. I charged it to 100% out of the box. I did 2 activities and in between turned off phone and gps. And in about 8 hours it drew down to 88%. I went to sleep with gps off, phone connectivity off and blood oxygen set to on demand. Heart rate monitor on. Activity tracking on. But overnight in 7 hours it drew down from 88% to 51%.
I restarted the watch. And it dropped 5% instantly. I restarted several more times, deleted the Connect app from my phone, re-synced and re-connected to the app and it's now drawing down about 1% per hour. I am using a stock watch face without seconds. No gps and no phone connectivity. Blood oxygen on demand. Heart rate monitor is on. Activity tracking is on.
Is this normal? So in 24 hours, it drew down to 36% from 100% fully charged. The watch is 1 day old. Please advise. What could be drawing down the battery so much? Is this working as it should? It seems to be using more battery than it should considering my gps and phone is almost always off?
Please advise,
Thanks,
