How long does it take to steal a mobile phone worth 1400 yuan?

No more than 2000 yuan, which does not constitute a crime in developed areas.

Article 264 of the Criminal Law: Whoever steals public or private property in a relatively large amount, or commits theft for many times, burglary, theft with a murder weapon or pickpocketing shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance, and shall also, or shall only, be fined.
