Extreme Battery Saver On GrapheneOS

batterysaver

I heard of an interesting feature called "Extreme Battery Saver" on Google Pixel devices past the Pixel 3. I have a Pixel 6.

I just do not know if there is a way to enable this feature when there is GrapheneOS? If there isn't a way this feature can be enabled within the GrapheneOS project and any requirements it has, would there be an alternative solution I could use to implement this feature?

I've seen Samsung's ultra battery saver mode on friends' devices before and I would love something like that on this great operating system.

I've heard about the FUTO grant and will be donating money myself and continuing to talk about this project to friends and family. I appreciate the work.

Hello!

You can read up on how Extreme Battery Saver works from the official Android documentation:
https://support.google.com/pixelphone/answer/6187458

Basically it pauses pretty much all non-system apps, which almost makes your Pixel phone a dumbphone. AOSP does not ship Extreme Battery Saver feature and it does not impact your privacy or security. That's why GrapheneOS does not have it.

You can utilize the Multiple Users feature to fully turn off groups of apps. For example you can use the Tidy Owner profile as an Extreme Battery Saver.

Hope this helps

I also have a Pixel 6.

No "extreme" battery saver, but there is a battery saver option. Once my phone hits 20% I get a notification to enable a battery saver thing, but I've never used it.

My phone lasts 16+ hours even when I use it regularly. I've never used any kind of battery saving feature.

Actually, I just checked my phone. It's at 30%. It's been 15 hours since it was unplugged and I have an estimated 6 hours left.

Extreme Battery Saver feature makes a lot of sense on stock Android where you have Google Assistant pre-installed. When turned on (default) it is always waiting for the Hey Google command. Moreover, it is listening and analyzing the background noise to figure out whether there is music playing nearby. This feature is called Now Playing and is also on by default.

Don't forget that basic things such as Bluetooth and NFC are also on by default on stock Android. Of course a GrapheneOS user would know how and why to keep them off, but think about an average Joe and his grandma.

Good point. My owner profile has been virtually untouched since I installed GOS. No apps, nothing. My owner profile just does remote attestation. I kill my main, "personal" profile before bed sometimes and just owner uses up something like 2-3% over the course of 7 hours.
