Why Would Samsung S7 Show Charging Symbol But Not Power On?

Hello all,

Im posting to ask how to fix a problem with a Samsung Galaxy S7 32GB Gold.

The phone is displaying that its charging when plugged in but the device will not power on. *ADD: The phone doesn't charge past 37%.

Multiple chargers have been tried. The battery was replaced on the unit about 2 months ago, could it perhaps be a faulty battery or is this a common error which can be fixed?

Thanks...
