It (probably) isn't. Look for Estel's original post on measuring capacity using bq27200 - the capacity measurement only reduces by a maximum of 12.5% on any one learning cycle. So, if it starts out at 2043mAH, which it often does from factory, or if you've previously calibrated it to a dual battery, then it'll be two or three cycles before you get a true measurement of your battery capacity. Repeat the same - charge to full and discharge to EDV1 - and you should get a measurement around the 1500mAH mark.

@Estel, your comments about PayPal are largely true - much like Visa or Mastercard, they cannot afford to lose buyer confidence or they and their brand are dead in the water, so they have almost always erred on the side of favouring the buyer. But it's by no means automatic - I've had to file 5 or 6 claims in the 8-10 years and several hundred transactions that I've been using PayPal (under 1% of my transactions have gone wrong) and in those cases where it's gone wrong, I've usually had to sit around for weeks whilst they await a reply from the seller, and in one case, a perfectly legitimate claim for items significantly not as described was wrongly decided against me. It's by no means as simple as complain and get your money back, except in those rare situations where a seller has been shut down for fraud.
