Mine recently died too. It started acting up shortly after either a firmware update or a watchface update, both of which occurred fairly close together. After messing with it for 3 weeks, I did a factory reset and it went kaput.
It was still under warranty, so I received an offer for a free replacement, or 50% off another model. I went with another model (Charge 3) since this was my second failed Ionic, and reading the forums, dozens (hundreds?) of others are having similar issues with both Ionic an Versa. Charge 3 has the basic functions I want (activity tracking, heartrate, and sleep) without all the sizzle. I figure simpler may be safer than sizzle. I just want a fitbit that might last a few years, though I'm not holding my breath.
