I got a Fitbit Ionic last Christmas. I reduced battery life in the last month and the watch went dead this weekend. I am back on my Charge 2.
I was looking at the Charge 3 which just came out, but it appears that not all the apps are functional and there are kinks. You may want to scroll through the Fitbit community site to see the issues new owners are experiencing. This one is directly relevant to you:
So, I have actually been perusing various reviews on the different Garmin models. Have decided one way or another yet. I am definitely not excited about going back to Fitbit.
I just want to update that when I posted the problem I had with my Fitbit Ionic on the Fitbit community website, a company support person reached out to me. Seeing that I have gone through the various troubleshooting procedures, the company rep has authorized the replacement of my Ionic.
Good service and support.
