General :: Samsung Transform Ultra Only Works Plugged In

I've had problems since the 4th month of this phone and its at a year now. It lost it's wifi back then and I managed to get it back by wiping it a number of times, both factory resets and android type.Other problems have occurred, I've taken care of them along the way. Now, the phone only works if it's plugged in. If it isn't, it goes dead. Shuts itself off immediately without a plug-in charge.

Btw, Samsung never would honor the warranty, citing they" don't replace phones but would "take a look at it" but couldn't "guarantee what they could do for it's software". I've had Samsung phones before and never had problems like this.
