Mine was at least that bad which is why I returned them yesterday. The headphones had lots of good parts but the battery didn’t work for me. The 9 hour battery may be accurate but they drained so quickly while not in use that I had to charge them every day. My old Plantronics headset only has a 6 hour battery (that maybe lasts 4 hours now) and I only charge it every few days.
If you use the Powerbeats an hour or two a day you will have to charge them just as often as though you used them 9 hours per day.
