Yes, it seems that synching and other problems are just getting worse with the One -- I finally moved on, and moved to a Charge 2. I have had a One (actually a couple of them) for about the same amount of time you have, and my problem with it was "washing it" in the washing machine with whatever pair of pants I had it in or clipped onto. My first One survived at least a dozen washings, and then its replacement really only managed a couple before it started having problems.
I also had big doubts about moving to a wrist-based tracker -- given how you can put your hands in your pocket when you walk, how on Earth can a wrist-based tracker POSSIBLY track your steps? And apparently, the answer is that "they are a bit more sophisticated than that," and it's definitely not just the movement of your wrist that makes it all work. I have actually found that the Charge 2 tracks my steps better than the One ever did.
For one thing, I found that my One utterly would not track much of any exercise but "walking." For instance, I have a glider machine at home, and a NuStep machine in a gym that I use, and the One really wouldn't track anything I did on them, with the tracker placed in my pocket where I usually kept it. So, I wound up clipping it to my pants around my knee, which tracked the activity, but with massively inaccurate results.
Meanwhile, now the Charge 2 accurately tracks both activities, referring to them as "elliptical" workouts, and that's close enough to what they actually are. Indeed, a whole new display was added to my online Fitbit Dashboard, showing the "recent exercise" with quite accurate results. It's really a whole new world of accurate and informative exercise tracking, which just doesn't exist with the One at all.
I had a few other concerns about wrist-based trackers, so let me go through those:
Display: I still really want a WATCH on my wrist -- I need to see the time and date and so on. The Charge 2 finally has a display on something short of a big watch-style device that simply gives you the time and date, along with fitness results. And it's a good, OLED display -- all far better than anything I've seen before, at least from Fitbit. You have a number of choices for the display, and I've chosen the number of steps and the heart rate, along with the date and time. And let me add one more thing here -- it's kind of neat to be able to see what's going on with your daily activity, right there on your wrist -- rather than hiding it all away in your pocket.
Sleep tracking: This is a VERY big thing for me. I have tried a couple of trackers from other companies, and their sleep tracking has been a JOKE. Absolutely, utterly useless. I firmly believe that Fitbit's sleep tracking is, by far, the biggest reason I will continue to use Fitbit trackers. But I really liked the concept that I TELL THE TRACKER WHEN I GO TO SLEEP AND WAKE UP. I really DO NOT WANT the thing to "figure it out automatically." So, here are my thoughts about this, so far with the Charge 2: For one thing, you can use a smartphone to tell it to start and stop, if you want to do that. And as for the automatic tracking, it's not too bad. Just over the past few days, in fact, I haven't been feeling well and have woken up at night a couple of times to spend some extended time in the bathroom (enough information about that!), and one time it actually reported two separate sleep sessions -- it added them up on the dashboard, and showed details about both of them in the detailed view. On another night, it thought that I was "done" with sleep like at 1:30 in the morning, even though I went back to bed afterwards. But, it's very easy to just go into the detailed view, and edit the "wake up" time (as well as the "went to bed" time, if you want to change that), and the true details will still show up just fine. So, if it doesn't quite track the start and stop times accurately, it's easy to go in and change them. In the end, this works quite well enough for me.
Strap: That's one thing that has scared the holy heck out of me -- other trackers have used a "pegs into holes" strap closure that was widely reported to fail often, and people would utterly lose their wrist-based trackers. But the Charge 2 uses a traditional watch-style buckle closure, so there's no problem with that at all. And there is already an enormous aftermarket for alternate bands -- go online and you'll find utterly dozens of different styles, colors, and so on, for good prices. And bands are quite easy to change, with a very secure attachment. So, I have no worries about the strap at all.
So, there are my thoughts about moving to a wrist-based tracker. Certainly, the Charge 2 is the first one from Fitbit that really attracted me, for the reasons I just described above. And with the sales going on right now (Black Friday 2016), you can get one for only $30 more than a Fitbit One -- I would certainly recommend at least buying one and giving it a try. And finally, I haven't had any synching issues at all with it. Now, it doesn't come with a Bluetooth dongle, if you need one for your computer -- but you can just use the one that came with the Fitbit One, which is what I'm doing. The installation routine will have you downloading and installing a new version of the synching program, since there's simply "more to be done" with the Charge 2 compared to the One, but again, it has worked flawlessly for me, so far.
I hope this helps -- I'm very glad I've gone for the Charge 2. And since it's something I "attach to my body," rather than to a piece of clothing, I have great expectations that I won't "wash my Fitbit" in the washing machine, ever again.
