Hi there,
I’ve had my forerunner 235 for 3 years. Have never had issues with the battery. Suddenly about a week ago battery started draining suddenly. Ie one morning after leaving the watch uncharged overnight with substantial charge i found it dead. Charged it so I could go running but drained really quickly from 50% and didn’t even make 30 minutes of a run. Since then the charge doesnt even last a full day and I’m lucky to get 2 hours of activity from a full charge. Is there an issue with an update etc that anyone is aware of because it was not even a gradual decrease.
