Hello. I have noticed that my Fitbit Ionic always seemed to overestimate my steps and also I seem to acquire thousands of steps at night, which I just assumed meant I move around a lot in my sleep, until yesterday. Yesterday, I left my fitbit charging all day, and even though it was just sitting on the counter, it calculated over 9,000 steps. Any thoughts?

Possibly caused by electromagnetic interference on accelerometer hardware. Assuming it is the case, the interference may be from the inherent design (perhaps a minor flaw in assembly etc) or an external source. 

Does it occur in all outlets. Does it happen at work or a friends home?   These can help narrowing down your external interference. Internal interference can't be corrected unless you send it back to the vendor.

So if I purchased a new band that is metal and the latch is a magnet, that
could interfer with the step counter? Particularly when I'm not wearing the
watch.

In quantum theory anything is possible. Field can be altered with a ferromagnetic material. 

Whether it would certainly happen is something that can't be said without actually measuring it. It depends on the magnetic intensity. Induced emf depends on intensity.  For more information, google Faraday's law.    

When I had the IONIC I did not experience this issue. Had I experienced the issue I would have attempted to figure out if it was due to electromagnetic interference and if so where the interference originates from or at least ruled out the electromagnetic interference. 

No matter how hard I think I cannot come-up with a reason other than electromagnetic interference for this problem. I don't believe vibration source has anything to do with unless you are talking about a vibrating jack hammer or similar. It is impossible that someone sleeps through a strong vibration. Subtle vibrations don't alter step count on my Surge and Blaze. I expect that IONIC is robust enough to weed through subtle change. Many folks would have experienced problems if it wasn't.

@Kitchensca

Do you think you can go buy a usb to usb ground loop isolator from a electronic store and try connecting to that isolator instead of directly? I wd make sure you can return the isolator if that doesn't provide relief. If in usa I wd usually go to something like Radioshack.
