Its not! It is defective
Sorry, there was a problem. Please try again later.Please keep in mind that when the case battery is used to charge the phone battery, the two batteries will equalize. The phone battery charge will go up and the case battery will go down to arrive at an "average" of the two batteries. If plugged in to a wall charger or placed on a charging pad, both batteries will get full charges.
Sorry, there was a problem. Please try again later.It is set up to charge the phone up first, then it charges the battery pack. I leave it plugged in until the battery pack is charge. You push the button on the back and if it is fully charged the lights are solid.
Sorry, there was a problem. Please try again later.The Juice Pac's battery capacity is 2,070mAh, but the Galaxy S9+'s battery capacity is 3,500mAh, so the Juice Pac was never designed to fully charge the phone, but you can get a good 60% out of it.
