Okay, as per title, I found iPhone 6 on the street, the battery is almost flat and I don't have iPhone charger.
What to do now?
If by the time the battery flat, the owner is not ringing me, what can I do with this iPhone?
UPDATE: Okay, I managed to purchase iPhone charger from local shop (as suggested below), and the owner called this morning and I returned the iPhone. Thanks for the suggestions guys!
The police can record the phone's IMEI. If the owner knows their IMEI (on the box, possibly invoice, I also believe you can ask your carrier) then they can report that to the police.
Years ago, a relative had their phone returned to them because they told the police the IMEI (after it was stolen).
(Police found the phone & looked up the database to see if it was stolen/lost, then connected my relative to return it).
As a last ditch effort, the owner can report the IMEI stolen and it will be blocked in Australia, so it cannot be used to connect to a mobile network in this country.
