It can be hard to know at a glance just where your iPhone battery stands. These Dynamic iPhone Battery Wallpapers from designer Ben Vessey make it easy. Sold in packs of three themes, each set contains three separate wallpapers, indicating whether the battery is in good shape, in need of a charge, or actively charging. One pack is dedicated to Apple-themed wallpapers, while the other is based on faces. They're optimized for every iPhone from the 6S on, require no jailbreaking to function — they rely on the built-in Shortcuts app instead — and include video and pdf installation guides.
