purchased headphones. Is this typical to receive 20 watts of charging from an iPhone 12? can be billed? Further. Charged fully; white light on. I then went to sleep while listening to music. The headphones were on. I listened to music for about an hour after waking up, spoke on the phone once for five minutes, and then led an online class using a macbook and bluetooth. The headphones are 85% charged, according to the connection before the lesson. taught for an hour. When the class was through, the charge had already increased by 5% after only 60 minutes. How is that even doable?
