我的手机没电了。

Grammar: Change of State Particle

This sentence uses the particle '了' (le) at the end to indicate a change of state, showing that the phone previously had power but now does not.

• 我的 (wǒ de): my
• 手机 (shǒu jī): mobile phone
• 没电 (méi diàn): to have no electricity
• 了 (le): particle indicating a new situation or change of state

Watch Out

Do not use '死' (sǐ, to die) to describe a dead battery in Chinese. Always use '没电' (méi diàn, literally 'no electricity').

When to use

This is the standard way to explain why you cannot use your phone, often preceding a request to borrow a charger or a power bank (充电宝 - chōng diàn bǎo).

Notes

Use this common set phrase to explain your phone battery is dead, literally meaning 'has no electricity'.
