You can let your Charge HR handle the bike workout (as d_thomas02 said), or, if you want to log it manually, you could log it in Fitbit (which would be my choice, if I didn't want to just let my Charge HR's data stand) or, if you really, really want to, you can log it in MFP, but my understanding (and my experience) is that MFP's method of estimating exercise calories is inferior to Fitbit's.

@mathiar86: I'd recommend reading the FAQ found in the stickies, if you haven't already. It will answer a number of your questions.

For golfing, I think letting your Fitbit handle it is probably the way to go, since it is pretty much just walking, so the step detection and HR measurements should cover it, and not log it manually. You could push the button to create an activity record and then relabel it as Golf, or see if it will automatically detect the activity.

MFP shouldn't be separately crediting you with 650 calories for the 12000 steps, though, unless your step source is set to your phone, rather than your Fitbit. I have no idea what effect that will have - I suspect it won't be good. If you're using a Fitbit for tracking your exercise then you should have MFP set to use it as the step source as well. I don't know if MFP has fixed it yet, but the step source bug causes MFP to calculate wildly wrong numbers if you have your Fitbit account connected to MFP but don't have Fitbit set as your step source.

Actually, it may recognize it automagically. I don't know, because I haven't played golf more than a dozen times in my life and the most recent was more than 30 years ago. It will automatically detect some things - walks, runs, "aerobic workouts" (such as Zumba), biking, "sport" and elliptical. I know it does fine detecting walks and runs, but there is a bug (I assume it is a bug) that causes it to not give a distance when it auto-detects those, so I usually use the button. But, I'm not sure if golfing will have enough continuous walking to be detected. I know shopping doesn't get detected as a walk. It also detects when I do Zumba (since distance isn't meaningful for that, I don't mind that it doesn't give a distance). I haven't tried biking since they added the feature (or elliptical ever) and I'm very fuzzy on what "sport" is but it's never detected it for me (fair enough, I don't think I've done anything that qualifies).

@NancyN795 yeah just noticed that it logged a 22:18 walk for me when I walked to the markets in the morning. Your right though, it may not log golf since I walk for about 2-3min which can be strenuous given the undulating terrain but then stop for about 2min to play the shot (or look for my ball...). I think I'll just use the stopwatch method for golf or other similar activities.

My next issue now is the battery life and a slight tilt in the LCD under the display. Can't tell when I look at it, but noticed when I took a picture to send to a friend. Also can only tell when call notifications are on since it slides from R --> L and the bottom 1mm is effected. Not a major issue but my OCD may get the better of me...

Battery life I'm hoping is just because its a new toy and I'm constantly checking it and syncing with my phone. I think I must have synced to my phone at least 10 times in 2 hours yesterday and something similar this morning. Hopefully as I get used to having it the novelty will wear off and I'll only check once or twice. I had charged it to full (presumably, does it ever say "full"?) and this morning I had low battery on the app.

@Owlfan88 - I don't think relabeling actually changes anything but the label.

@mathiar86: You're probably out of luck getting warranty service. I bought a couple of Fitbit Ones off eBay and when the battery in one of them died, that was that. Fortunately, I'd given the other one to my sister and she had decided that a Fitbit wasn't for her, so I just got it back from her and used it. It was a relatively inexpensive way to learn that I got a lot of value from a Fitbit, so when I washed that One, I took the plunge and ordered a Charge HR (the One came back to life, I gave it to a friend, and over a year later it still works).

My husband and I are suspicious that some of the Fitbits that show up on places like eBay are devices that didn't quite pass quality inspection for some reason (marginal battery, slightly tilted display, ...) but somehow got out of the reject bin and onto the black market.

If your battery continues not even lasting a whole day, you could try doing a reset (plug it in and hold the button until you see the version number). That might make a difference. Or, it might not, but it won't do any harm.
