Samsung Loses Apple Patent Case

Incorrect, Batteries go bad before devices in most cases, as a customer can use a good phone 2+ years (specially those who are on 2 year contracts) and batteries have a possible 1 to 1 1/2 yr usage built in with between 450-650 cycles. A cycle = 1 charge no matter the time, 2 mins or 2 hours. 365 days a year + plugging in your phone a minimal of 2 times a day = 730 cycles, way way over the maximum amount of capacity a battery normally holds.

Plus, its a warzone out there with all the 3rd party chargers incorrectly used to charge batteries at incorrect voltages, so I often see swollen/pregnant batteries because little johnny on lunch break with his friends or Mr. Johnson out on car pool for lunch with the coworkers uses his buds micro usb charger rated at the incorrect voltage specified for his phone overcharges it turning it into a swollen mess of cells. So no, Majority of the time, the Battery is needing to be replaced before a device.

That has been my experience the past 16 years.
