意味

Battery dead — the state of a device having completely run out of charge.

A straightforward compound of 充電 (charge/charging) and 切れ (cut off/exhausted), 充電切れ is the go-to expression for when your phone or device dies. While technically standard Japanese rather than slang, it has become so frequent in daily speech — especially in LINE messages and excuses for not replying — that it functions as essential modern tech vocabulary.

例文

1. ごめん、充電切れで連絡できなかった。
2. モバイルバッテリー忘れたから充電切れが怖い。
3. ライブ中にスマホ充電切れになって写真撮れなかった。
