Wrong. Look around, and stop spreading fud. People are losting 20%+ while they sleep, losing 30% or more in less than two hours. There is a definite problem with *some* phones. Mine's not one of them thankfully.
I'm pretty sure it's not some phones but rather the way some people are using them. I lost nearly 20% just a couple of hours while I was sleeping, so when I woke up I turned off my geo-fenced reminders and put it back on to charge. Now after a full day with plenty of Siri use, playing music via Bluetooth, etc. it's down just 30%.
