Review: Heavy & Big - Unfortunately they can't used a real 5,000 may battery. So they give you some Chinese junk which is always 80% thicker than a normal samsung battery. So this case really is only big because they need to save a couple pennies and screw your pocket over.......... Other than that, it is how it is, there no one else selling a s20 fe battery case?
Review: Effective charging phone case! - This did fit my phone exactly, and it held up really well for a concert I needed it for.
