Full battery to empty in 12 hours

Hi guys,

Twice now I have charged the battery and it has emptied in less than a day without using any GPS and/or any activity sports tracker function. Do you guys what it could be? Thanks.

Mine has been acting strange recently as well. Yesterday it was around 60% charge and I turned on HR broadcast for an hour ride. When I finished, it had gone into battery save mode. It did transmit HR for the entire ride, but the battery was down to 15-20%. A half hour after the ride, I recorded a 50 minute "hike" while leaf blowing trails and it recorded the whole time without issue, then was fine overnight except it did not record pulse OX which has been happening when the battery is under 10%.

Mine was purchase new in spring of 2021 on discount when the Instinct 2 had been released (I think) and it has been dependable until now. I have been looking at new options and waiting to see what holiday sales there may be.
