---Question: Do battery cases ruin your phone?<br>---Answer: The lithiumion battery inside your phone WILL NOT degrade due to your use of a mophie juice pack. One person wrote that the battery will be ruined because mophie will not completely charge the phone to 100%. ... It does not hurt the phone to charge to 100%, it just does not hurt it to do otherwise.<br><br>---Question: What is a power case?<br>---Answer: The cases are sliding cases that feature an inner sleeve and a removable outer sleeve. The inner sleeve is a dual-layer case. The outer sleeve serves as an external power source that charges your phones battery. ... These chargers automatically power down when your phones battery charge has reached 100%.<br><br>---Question: How long does it take to charge a battery case?<br>---Answer: How long does the charger case, itself, take to charge? A fully depleted charger case takes about 3 to 4 hours to be charged 100% again.
