Motorola's "Improve battery while inactive" feature kills apps in background every hour no matter if the settings is enabled #1142

I'm not sure what Motorola devices are affected, but mine surely is. Moto G64 5G comes with the following packages installed by default:

package:com.motorola.batterycare.overlay.settings.cancunf.retin
package:com.motorola.batterycare.overlay.appside
package:com.motorola.batterycare
package:com.motorola.batterycare.overlay
package:com.motorola.android.providers.settings.overlay.batterycare.retin

This batterycare app adds another "Improve battery while inactive" option to Settings > Battery. July security patch for Android 14 which I recieved a few days ago seems to have introduced an update to Motorola's batterycare app as well. Earlier apps weren't killed, but after the update apps are killed every hh:00 (atleast Termux is killed, I didn't test for other apps).

A fix is to uninstall the com.motorola.batterycare package using adb: adb shell pm uninstall -k --user 0 com.motorola.batterycare, this also removes the additional "Improve battery while inactive" setting Settings > Battery. It doesn't matter if this switch is on or off, apps seem to get killed. Removing batterycare fixes the issue.

"Improve battery while inactive" setting in Settings > Battery when the app is installed (which by default it is: image

When batterycare is uninstalled using adb: Screenshot_20240804-095318

Output of adb shell dumpsys activity exit-info com.termux just after the app was killed:

I'll try to see if I can obtain some logcat output as well related to the same.

I was quite shocked when I found that it was indeed a motorola service that was messing with background apps, generally I've found Motorola to ship mostly stock android with an app that gives a really nice introduction to the phone and quick gestures.

Hi @thunder-coding, I am just about to create a new section for Motorola phones, as the evidence is mounting... sad to see Motorola joining the dark side.

Do you have any experience with the Adaptive battery? Does it make any difference on this phone to have it on/off?

I have a report about "managing background apps" - the user was not able to locate this "optimization" in the layout, but found it with the search tool.
