Watch 5 body composition measurement is way off

[Mechajin]

Is there any way to improve the accuracy of the body composition measurement?

I'm a power lifter, so quite big but mostly muscle. Using calipers I have a body fat percentage of 19% but using the watch it thinks I have 31% body fat. That's not just a little inaccurate, that's way off. Up or down 1-2% is no big deal but 12% makes it unusable.

Any way to improve accuracy?

Try GymRun. It's what I use. It records the workout as "weight machines" or "other" (you choose) + HR + Calories and syncs it to Samsung Health automatically after finishing your sets!

I completely agree. I have verified 14% BF; however, the Samsung Galaxy Watch 6 measures me at 22.5%. Why would Samsung even have an app that is this inaccurate? There is, of course, no physiological way that the watch can give an accurate impedance reading through two fingers; however, Samsung could have...at the very least, included some standard body measurements in their algorithm to come up with something a little more realistic. In its current iteration, it is utterly useless.

Tried to lick my fingers this morning... took off 2.5% bodyfat... and increased skeletal muscle the same ammount... sick... But still about 6% off for me But I gave up on this accuracy a long time ago...Even FitBit Charge 2 (The small one yes) was more accurate then GW5P...

• I totally agree my DEXA scan had me with around 116.1 lb of skeletal muscle and 29.8lb 13% body fat. The watch said I was 100.8 lb of skeletal muscle and 47.9 lb of body fat 21% if I cut 25lb of fat right now it would kill me literally but going my the watch I would be just about 10% body fat. They need to stop advertising this as accurate for muscle people.

Same here. The In Body machine at the gym measures my body fat at 11.8% and my Samsung Ultra Watch first came back with 21%. I tried the "lick your finger" fix and it came back at 22%

My wife tests normally at around 25% and when she tested with the ultra watch, it said she had 7% body fat.

2 very inaccurate readings from this watch.
