Fat Mass + Lean Mass Measurements

Have you tried contacting the Withings Customer Support? If you haven't done so, you can reach out to them by following this link https://support.withings.com/hc/en-us/requests/new. They will be able to help.

I have the same issue, and looking across the fora plenty of others do too. I will send a Note to Withings via the link, but given the widespread nature of this issue I would have thought that if there is a solution they should look to use a forum to let users know what it is.

Same here. Have sent a request and will see what they say.

I too had this problem - the fix was pretty easy. It won't do lean/fat mass if the batteries are low. Try fresh batteries.

Will change them. They are on 33% so would have thought that's ok....

Mine were at ~33% too. Like the OP, I have had this scale since 2010 or so, with 0 problems. Then I get this issue with the fat/lean mass readings. I called and spoke with one of their programmers who connected remotely to the device (as I recall), and said the relatively low battery was the issue. I thought it was a lazy answer... then I changed the batteries.

Its back up to speed.

I'm not sure why it suddenly doesn't work when the batters are lower than a third or so. That is a new issue.

I have the same issue right now - I put new batteries into the scale, yet the device STILL shows that the batteries are low on the scale and is not taking the Fat Mass measurement.  However, when i look at the device in my dashboard it shows the batteries at 99%.   Any ideas?  

I too am having this issue. I updated the batteries and it's showing 91% but I'm still unable to get my Fat % any longer. I then disassociated this from my account, removed batteries for 1 minute and then set it back up once again. Still not having any fat % readings. I emailed support roughly 2 months ago and my inquiry went unanswered. 

This is appalling support for a product. I realize it's quite old now but it's also a lot more simple than before. This is also a basic function the device was meant to have out of the box. Does anybody have any other options for resolving this? 

I figured mine out - I realized that mine wasn’t syncing fat mass due to the scale not recognizing the battery being replaced. I took the batteries out and cleaned the terminals and put the new batteries back in and it worked after that. No problems since. I used a Q-Tip with a little rubbing alcohol to wipe down each terminal and then dried them with another dry Q-tip.

As crazy and unbelievable as this is, I cleaned my leds and replaced batteries and today, voila! I’ve got my fat mass measurement back again.

Thanks for this tip. I never would have thought of it and probably replaced the scale (Like Nokia would likely want me to do).
