My girlfriend and I both have a Forerunner 45 and have both noticed a sudden drop in battery life since the last update. I don't remember exactly when, but we both noticed that especially during activities with GPS enabled, the battery drains incredibly fast. We hiked for about 45 minutes yesterday and my battery went from 40% to 1%. I used to be able to ride my bike to work for two days (30-40min one way trip). The result is that we both have to charge our watches once every 2-3 days. I worry that I can no longer track our longer, multiple hour hikes with this watch.
If this were happening to just my own watch, I would suspect the battery is dying and I need to replace my watch soon, but since it is happening to both our watches at exactly the same time, I suspect that something changed during the last update. However, I have not found anything that would explain the battery drain. Do other people have the same experience?
