What do you want to find out?
For years, Google Maps Timeline worked in a simple way:
new phone + same Google Account = all past trips automatically reappeared.
But since Google’s major Location History update at the end of 2024, that old rule no longer applies. Timeline is now stored differently, synced differently, and requires new steps to keep your trip history safe.
If your Timeline looks incomplete, trips are missing, or nothing appears after switching phones, this article explains exactly why — and how to fix it.
What Changed in Google Maps Timeline?
Google rolled out a major update moving Timeline (also known as Location History) from the cloud to your device.
Here’s what that means:
1. Timeline is now stored locally, not automatically in your Google Account
Previously:
All trip history synced to your Google Account.
Switching phones brought everything over instantly.
Now (2025):
Timeline data lives on your phone’s internal storage.
Your Google Account alone does not keep your travel history.
This is why past trips may not show up automatically when you get a new device.
2. The old web Timeline is disappearing
Google announced that the web version (timeline.google.com) will eventually phase out because Timeline is now device-based.
You can still view and manage Timeline in the Google Maps app, not on the web.
3. A new feature was added: “Timeline Backup”
To replace the old cloud-sync system, Google introduced a separate backup system specifically for Timeline:
Your trips are backed up encrypted to Google servers.
You must turn this feature on manually.
It allows you to import your Timeline onto a new phone.
If this backup wasn’t enabled, your Timeline likely exists only on your old phone.
Will My Timeline Transfer to a New Phone?
The correct answer in 2025 is:
It depends entirely on whether Timeline Backup was enabled.
Let’s break down the two scenarios.
If Timeline Backup was NOT enabled
Then your past routes and trips are stored only on the old device.
When you switch to a new phone:
General device migration tools might bring the data over
but Google does NOT guarantee this
Many users report partial or missing Timeline history after switching phones
So in this case, past trips may not appear at all unless you still have the old phone and enable backup.
If Timeline Backup WAS enabled
Then good news:
Your Timeline was encrypted and saved online
You can import it on your new device
How to restore Timeline on your new phone:
Open Google Maps
Tap your profile photo
Go to Your Timeline
Tap the cloud icon
Select Import
Your historical data (as far back as your auto-delete settings allow) will appear on the new phone.
The Auto-Delete Problem (Most Users Don’t Know About This)
Google changed the default auto-delete period for Location History to 3 months.
If you never changed this setting:
Anything older than 90 days may already be permanently deleted
Even with backup enabled, you can only restore what wasn’t auto-deleted
To check your setting:
Google Maps → Profile → Your Timeline → Settings → Location History → Auto-delete
If you want to keep multi-year history, set it to:
36 months, or
Do not auto-delete
How to Protect Your Timeline When Switching Phones
If you want to make sure you never lose years of travel history again, do this on your current phone:
Step 1: Enable Timeline Backup
Google Maps → Profile → Your Timeline → Cloud icon → Turn on Backup
Step 2: Adjust Auto-Delete Settings
Set the auto-delete window long enough to keep your past years.
Step 3: On your next phone
Google Maps → Profile → Your Timeline → Cloud icon → Import
That’s it.
Quick Summary
Timeline is no longer automatically synced to your Google Account
Your trips now live on your device, not in the cloud
Old Timeline data may not transfer to a new phone
The new Timeline Backup feature is required for safe transfer
Auto-delete may remove your older trips unless you extend the limit
If your Timeline appears incomplete or missing, it’s usually because:
Backup was off, or
Auto-delete removed older data, or
Phone-to-phone migration didn’t include Timeline storage
How MileageWise Fits Into This
MileageWise’s Google Maps Timeline Import feature can only convert the data that currently exists on your device.
If Timeline data is missing due to Google’s new system, backup settings, or auto-delete, it cannot be recovered.
This is why keeping your Google Maps Timeline backup turned on is essential — especially if you rely on Timeline to create IRS-compliant mileage logs.
