Lithium-Ion batteries lose capacity as they age. It’s just a fact of live. The more you charge and drain them, the more capacity you lose. After a year or so, the difference in capacity is fairly significant, and it only gets worse as more time passes. Want to do something about it without having to give up your phone and pay to have the battery swapped? Check out the XDesign iPhone 8/7/6s/6 Battery Case, which works with all four models and costs just $14.99 on Amazon.
