The saddest icon in the world

In my opinion, change the battery is the saddest icon in the world. Neither standard error symbols nor minor versions of emoticons can compare with it. The appearance of a crossed-out battery on the screen of a device often causes a deep groan in a person. The cries follow: “No, well, a little more, a little more!”. Moments full of drama. In the seconds remaining before turning off, I want to fit the clock :) The maximum thrill.

Of course, there are other icons no less vivid in their passions. No network, empty tank icon, Check Engine. If someone has other options (namely, on-screen icons, it's not about warning symbols, as such, say signs of radiation hazard, etc.): offer it!
