These biometric bathroom scales are notoriously inaccurate. They should not be used to measure your body fat in terms of accuracy.
However, they can be a helpful precision tool. What you can do is use the body fat % it shows as a point of reference. Check once a week and create a graph where every week is a data point and make sure over the course of months you are in a steady decline. You just have to make sure that you are doing things under the same conditions. Simply drinking a pint of water before your weigh-in will raise your body fat measurement by about 0.5-1% on these scales. That's a huge deal. It's best to pick one day a week and measure it right upon waking. For example:
1.) Maybe choose a Friday morning since your weeks are less variable than weekends, where food intake and activity can fluctuate wildly whereas during a work week you're adhering to a similar eat/sleep schedule and probably not going out at night and indulging.
2.) Measure immediately upon rising.
3.) Go pee first so you flush out all the water sitting in your bladder all night so it doesn't throw off the reading.
That could make your scale a very good precision tool.
