This is a No Battery icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
It is a logo for a dying battery. It is a battery shape but with a line through it stating that it is either low or that it is dying. It has lines going vertical to display how many bars are left that are still charged.
