I'm not sure this is true. Rechargeable batteries, including those installed in electronics devices, are always sent at least partially charged from the factory to prevent the battery from over-discharging while it sits on a shelf, but in my experience, you always get full capacity the first time you charge it. There's no "break in" period. It might seem that way, but I suspect it's a matter of perception because you're more likely to use a new device more often which will run the battery down faster, and once the novelty wears off and you just use it normally, the battery will last longer.
The rest of your post appears to be correct, that the charge indicator on an electronic appliance represents an estimate rather than a precise value.
