I have Forerunner 235 for three months - love it - Normally the batter lasts over a week. Yesterday battery was down to 10% so I charged to 100% and then was dead in about 10 hours. GPS was in off mode, I only have one face app loaded & device is already updated to latest version which rules out bluetooth update draining battery. I have spent much time research why this could happen and called garmin support. The only thing they had to offer was delete history files, but only after three months, I cannot imagine that would drian a battery in 10 hours vs normally a week. Anyone else experince this and has possible solution?
