Auto Message After CallPixel unrestricted battery setting for Auto Message After Call
Pixel unrestricted battery is the per-app setting that removes background limits on Google Pixel phones. Auto Message After Call uses it to stay ready for the end of every call.
Pixel unrestricted battery removes background limits for one app on a Google Pixel, so Auto Message After Call can react whenever a call ends.
Google Pixel phones manage each app's background activity through a setting called Allow background usage, reached from the app's battery page. Google's help centre describes the path as Settings, Apps, See all apps, the app, App battery usage, then Allow background usage, and recommends Optimized for most apps because it lets Android learn when an app is needed. Auto Message After Call is an exception worth making. It has to wake up at the exact moment a phone call ends, and an optimised app can be held back while the phone is idle, which delays or skips the WhatsApp message. Choosing Unrestricted for this one app removes those limits without changing any other app. Google's Adaptive Battery feature can stay on for the rest of the phone. Some of these menu names apply to Android 14 and newer; on older Pixel software, look for Battery optimization under the app's settings instead.
Pixel unrestricted battery steps
- Open Settings, tap Apps, then See all apps.

- Tap App battery usage, then Allow background usage.
- Select Unrestricted.

The menu path follows Google’s Pixel help page on battery optimisation, which notes that some steps need Android 14 or newer.

Pixel unrestricted battery FAQ
How to allow unrestricted battery usage?
On a Pixel, open Settings, Apps, See all apps, choose the app, tap App battery usage, then Allow background usage, and pick Unrestricted.
Should I turn off the adaptive battery Pixel?
No. Keep Adaptive Battery on for the phone and set Unrestricted only for the apps that must react instantly, such as this one.
Does unrestricted battery drain my Pixel faster?
It can for heavy apps. Auto Message After Call mostly waits for calls, so the difference is usually small.
Why does Google recommend Optimized?
For most apps, letting Android decide saves battery without harm. Apps that must respond to phone events at once are the exception.
Where is App battery usage on Android 13 or older?
Older Pixel software shows Battery or Battery optimization inside the app's settings. Set it to not optimized for this app.
Do I need to do this after every update?
Usually not, but check the setting after a major Android update if messages stop.
Will the app work on Optimized?
It may work while you use the phone, but messages after calls can be delayed or missed when the phone sits idle.
Does Restricted stop the app completely?
It limits background work so much that the app will usually miss the end of calls.
Does this apply to Pixel Fold and Pixel tablets?
The same App battery usage setting exists on Pixel Fold. Tablets without phone calls do not need the app.
Is there a Pixel video in the app?
Yes, a Pixel clip sits in the battery step of the app's own setup guide.
What about the 80% charging limit on Pixel?
That is a charging setting to protect battery health and does not affect apps. You can leave it as you prefer.
Do I need Accessibility as well?
Only if you want messages sent with no tap. Battery and Accessibility are separate settings.
How do I check the setting worked?
Leave the phone locked for a while, get a test call, then unlock; the WhatsApp should be sent right away.
Will other apps change?
No. Unrestricted applies only to the app you select.
What if the message still does not send?
Check the call type is on, the template is active and the caller is not filtered, using the support page's fix table.
