When the battery drops to about 46% the phone goes black and drops to 0%

A bad battery, perhaps.

Battery is shot and can no longer handle the demands of the phone without the voltage sag dipping below the cutoff point. The only fix is to replace the battery. If you do replace it, try to keep it between 40-80% charge for the most longevity.
