What to do if you lose your cell phone?
If you lose your phone, it's important to stay calm. The first thing you should try is to call your lost iPhone. If you can hear it nearby, you can quickly narrow down the search area. If you can't hear it, don't worry.
You can use the "Find My iPhone" feature. However, this feature must be enabled beforehand. Take a moment to calmly organize the situation and try the steps below.
How to use Find My iPhone
Find My is a service provided by Apple that allows you to track the location of your device if you lose it. Using this feature, you can check the location of your iPhone on a map and play a sound to help you find it in your surroundings. You can also remotely lock your device to protect your personal information. Here's how to use Find My iPhone, officially provided by Apple:
Access iCloud
- On your computer or your friend's iPhone, open a web browser and go to iCloud.com .
- Log in with your Apple ID and password. This will take you to the iCloud dashboard.
Open the Find My iPhone app
- From the iCloud main screen, find and click the Find My app.
- Once the Find My app is open, click on the " All Devices " option at the top of the screen. This will display a list of all your Apple devices.
Select the lost iPhone
- Find your lost iPhone from the list and select it. Once selected, your iPhone's current location will be displayed on the map.
- Use the map to find your iPhone's exact location.
Take action on your iPhone
- Make a sound: If your iPhone is nearby, select the "Make a sound" option. Your iPhone will start ringing, so you can use the sound to find it.
- Lock it: You can remotely lock your iPhone with a custom message and contact number so that if someone finds your iPhone they can contact you.
- Erase Data: If you can't find your iPhone, you can choose the "Erase Data" option, which will erase all data on your iPhone but will disable the Find My feature after erasing.
Can I find my lost iPhone even if it's turned off?
Even if your iPhone is turned off, you don't have to give up completely. In fact, there is still a chance to find your iPhone using the Find My feature. Check the following points.
Enabling Find My network feature
On your iPhone, in Settings - [Apple ID] - Find My, you not only need to turn on Find My iPhone, but also turn on the Find My Network feature.
If your iPhone is an iPhone 11 or later model with a U1 chip, the "When in Power Saving Mode or Off" option will be available in the "Find Network" settings. This means your iPhone must be an iPhone 11 or later model (excluding the SE series).
Use Find My to locate your device
If your iPhone is lost or stolen, log in to the iCloud web version or Find My app from another device and access the "Find" feature. Select the lost iPhone and enable "Lost Mode". Even if your iPhone is turned off, it will automatically send its location information and you will receive a notification when it is restarted and connected to the Internet later.
So, there are some ways to find your iPhone even if it is turned off. However, if your iPhone is completely turned off, it will not update its location and will not connect to a network, making it harder to find.
