When i press the button on my battery, the light flashes purple/pink on every press but will not turn blue. I have tried multiple presses (to turn on/off) but still get the flashing button. When I plug in my USB charger, the light on the charger is green, but the light on the battery flashes pink/purple once then turns orange, and seems to flicker every 3 second or so while plugged in. I just bought it one week ago. I charged it overnight, and tried to clean the connections but no luck.
