Read your iPhone charge by the battery icon's color alone

BatteryHue is an iOS profile maker that gives each charge level its own color, and it never needs a jailbreak.

Pick a color style, then install the profile on your iPhone.

Words you meet along the way

Battery icon: The little battery glyph at the top right of your iPhone screen. BatteryHue changes the color of its fill; the icon keeps its usual spot and shape.

Charge level: How full the battery is. You give low, half and full a color each, so a look at the icon tells you where you stand before you read the number.
Color style: The look you pick on the next screen: plain colors, a gradient, or an animated effect on top.
Configuration profile: A small settings file iOS knows how to install. BatteryHue generates one with your color style inside, and your iPhone asks you before it applies anything.

Effect: Movement added to the colors, such as an animation or a shifting gradient. It is optional: a still color works just as well.

Jailbreak: Changing iOS so it runs software Apple does not allow. BatteryHue does without it: the profile route works on a normal iPhone.

Profile Downloaded: The line that appears near the top of Settings once the profile is on your phone. Tap it, then Install, to apply your colors.

Settings, VPN and Device Management: Where installed profiles live, under Settings, then General. Remove the BatteryHue profile there any time you want the stock icon back.

You see the color styles and pick plain colors, a gradient or an effect.
You watch BatteryHue build your profile with that style inside.
You see iOS ask to install it, and once you confirm in Settings, the battery icon shows your colors.

Open the next step on the iPhone you want to color: the profile installs on the device that downloads it.

Pick the color your battery shows at every level.
