Not sure where you get that idea from. ..

"As for battery life, we've been pleasantly surprised. The 1785 mAh battery is a respectable size. Standby time has been excellent (that isn't always the case with Verizon LTE devices), and the Droid 4 holds its own in actual use. LTE data still eats through a battery, but things are getting a little better in that respect. As is always the case, your mileage will vary. But we didn't have any real issues to report, except that phone didn't like to charge on a lot of the USB chargers we have just laying around. You'll likely need to use the included one."
In the D4 you have a $550 phone that its retailer considers worn out, 'totaled', when the battery wears out. By the vzw definition, the life of the battery *is* the life of the D4. If I owned one I'd want to be extra careful about such things as charging regimens...
Perspective instantiates reality.
