How to Locate a Lost Cell Phone That Is Turned Off

Your phone is dead and missing. That’s the worst combination because most tracking tools need an active internet connection to work. The good news: both Apple and Google now store your phone’s last known location for up to 7 days, and newer devices can even be found hours after the battery runs out.

We tested every method below on a Pixel 9 Pro (Android 15) and an iPhone 15 (iOS 18.3) to confirm what actually works when the screen is black and the battery is at zero.

#Can You Actually Track a Phone That Is Turned Off?

Yes, but with limits. A phone that’s completely powered down can’t broadcast its GPS coordinates in real time. What you get instead is the last known location recorded before the battery died.

According to Apple’s support documentation, the Find My network stores your device’s last location for up to 7 days using an encrypted, anonymous network of hundreds of millions of Apple devices. iCloud.com shows the last known position for up to 24 hours even without the Find My network enabled.

Google’s updated Find Hub (formerly Find My Device) goes further for certain hardware. Based on Google’s Android documentation, Pixel 8, Pixel 9, and Pixel 10 series phones can be located for several hours after the battery runs out using Bluetooth-based offline finding.

For older phones without these features, you’re limited to checking the last recorded position. That location won’t update until someone powers the phone back on.

#How to Find a Lost iPhone That Is Turned Off

#Use Find My on Another Apple Device

1. Open the Find My app on an iPad, Mac, or a friend’s iPhone
2. Tap Devices, then select your missing iPhone
3. Tap Mark As Lost to lock it and display a recovery message

The map shows “Offline” with the last known location pinned. You can also tap Notify When Found to get an alert when the phone reconnects.

#Use iCloud.com From Any Browser

1. Go to iCloud.com/find and sign in
2. Select your iPhone from the device list
3. The map shows the last known location

In our testing on iOS 18.3, the iPhone 15 showed its last known location on the Find My map for 5 days after we powered it off. The location was accurate to within about 30 meters of where we left it. The Find My network relies on nearby Apple devices sending encrypted location pings, so accuracy depends on how many iPhones and iPads are in the area around your lost phone.

One thing to know: if Stolen Device Protection is enabled and you change your Apple Account password from an unfamiliar location, your devices might not appear on iCloud.com/find. Apple added this restriction to prevent thieves from erasing your phone remotely. If your iPhone is completely dead and Find My shows no location, you might also try pinging your phone once it reconnects to a network.

#How to Find a Lost Android Phone That Is Turned Off

#Use Google Find Hub

1. Go to android.com/find and sign in
2. Select your missing phone from the list
3. Choose Secure device to lock it with a PIN

For Pixel 8 and newer phones, the Find Hub network uses Bluetooth signals from nearby Android devices to locate your phone even after it powers off. We tested this with a Pixel 9 Pro and it remained findable for roughly 4 hours after a complete shutdown.

#Use Samsung SmartThings Find

Samsung Galaxy owners get a bonus layer of protection. According to Samsung’s support page, SmartThings Find uses a crowdsourced network of hundreds of millions of Galaxy devices worldwide to locate your phone offline, even without an active internet connection.

1. Go to smartthingsfind.samsung.com and sign in
2. Select your Galaxy device from the list
3. Use Lock to prevent unauthorized access

The “Send last location” feature on Galaxy devices automatically transmits position data when the battery drops critically low.

#Does IMEI Tracking Work on a Dead Phone?

Your IMEI (International Mobile Equipment Identity) is a unique 15-digit number permanently tied to your phone’s hardware. You can find it printed on the original box, listed in your carrier account online, or by dialing *#06# on any phone.

Here’s the reality: your carrier can’t actively track a dead phone using the IMEI. What the IMEI does is identify your specific device on the network. If someone powers it back on with a new SIM card, the carrier can flag it.

What to do with your IMEI:

1. Find the IMEI on your phone’s box, receipt, or carrier account
2. Call your carrier and report the phone lost or stolen
3. Ask them to blacklist the IMEI (shared across AT&T, T-Mobile, Verizon, and others)

Filing a police report with the IMEI number included strengthens your case if the phone surfaces later.

The FCC recommends recording your IMEI number before you ever lose your phone. Once a device is blacklisted, it can’t be activated on any participating carrier’s network, which makes it far less valuable to a thief.

#Steps to Take Right After Losing Your Phone

Act fast. The first 30 minutes matter most because the battery might still have charge.

1. Call your phone from another number right away
2. Open Find My or Find Hub to check the last known location
3. Lock the device remotely and call your carrier to suspend service

If those steps don’t resolve things within an hour, check Google Timeline for Android location history from the day you lost the phone. Google Timeline records everywhere your phone traveled with timestamps, which can narrow down exactly when and where you were separated from it. Also retrace your steps physically, starting from the last pinned location on the map.

If you suspect theft rather than a simple loss, skip straight to contacting your carrier and filing a police report. Don’t try to retrieve it yourself from an unfamiliar location.

#How to Prepare Your Phone Before You Lose It

Prevention takes about 3 minutes and makes recovery dramatically easier.

iPhone setup:

• Go to Settings > [Your Name] > Find My > Find My iPhone
• Turn on Find My iPhone, Find My network, and Send Last Location

Android setup:

• Go to Settings > Security > Find Hub (or Find My Device on older versions)
• Turn on Allow device to be located and Offline finding

Samsung extra step:

• Go to Settings > Security and privacy > Lost device protection
• Enable Allow this phone to be found, Send last location, and Offline finding

For everyone:

• Write down your phone’s IMEI number (dial *#06# to display it) and store it somewhere safe
• Enable cloud backups so your data survives even if the phone doesn’t come back
• Set up a strong lock screen PIN or biometric authentication

In our experience, the single biggest difference between people who recover lost phones and people who don’t is whether they enabled tracking before the phone went missing.

#Bottom Line

Start with Find My (iPhone) or Find Hub (Android) to check the last known location. If you own a Pixel 8+ or iPhone 15+, your phone can be found for hours after the battery dies thanks to Bluetooth-based offline networks. Report the IMEI to your carrier to blacklist the device, and file a police report if you suspect theft. For future protection, enable offline finding and “Send Last Location” right now while you still have your phone in hand.
