OpenCase is an iPhone case that significantly reduces the issues with MagSafe accessories. It does this by creating an “open” space that holds the MagSafe accessories (we call this the “Accessory-Hold” area). It makes accessories thinner, it makes the case lighter, and it holds MagSafe accessories much more securely.
It’s a really good idea! I don’t typically use a phone case, but this seems like a solid solution to MagSafe fiddliness.
