Abstract: A portable electronic device and a positioning method are provided, so as to improve positioning precision. The portable electronic device includes: a processor, configured to determine a first scan interval; and a transceiver, configured to receive a beacon signal by using the first scan interval as an interval. The processor is further configured to: obtain a first positioning result according to received signal strength of beacon signals received by a receiver in m continuous first scan intervals, and determine an average quantity of scans according to the first positioning result; the transceiver is further configured to: when the average quantity of scans is greater than a preset value, receive a beacon signal by using an increased second scan interval as an interval; and the processor is further configured to obtain a second positioning result according to received signal strength of beacon signals received in p continuous second scan intervals, where m and p are integers greater than 1. The scan interval is adjusted according to the average quantity of scans, so that positioning precision is improved.
