Battery draining

GHqBD_1942

I'm going to try reinstalling the system from a computer. Can I use fedora with Librewolf?? or I need specifically the system and browser that says on the website.

GHqBD_1942 fedora

Should be able to.

Librewolf

No. Firefox browsers don't have WebUSB if i recall.

need specifically the system and browser that says on the website.

Ideally yes. That's why the instructions have them.

GHqBD_1942 Can I use fedora with Librewolf??

It's highly recommended to use a Chromium-based browser like the ones listed in the install section on GOS' website. You could simply install Brave (but disable Brave shields before and during the installation). Fedora is not officially supported but it may work. You may have to install some additional packages like android tools, add udev rules for that and maybe other stuff. It could be a little complicated, see here: https://discussion.fedoraproject.org/t/help-installing-grapheneos-from-fedora/114113.

If you have the chance to use one of the officially supported systems, it might be better to do so.

linux-dev

GHqBD_1942 FYI, I just used the tool with a report for my pixel 9 and grapheneos 16. It still works, but you have to pull from docker:

In order to properly create a report you would do the following:

adb shell dumpsys batterystats --reset
adb shell dumpsys batterystats --enable full-wake-history

Then let the phone sit for a few hours, then create the report:

adb bugreport battery.zip

Now spin up battery historian docker:

docker -- run -p 20000:9999 itachi1706/battery-historian:stable-3.1 --port 9999

open a browser an go to localhost:20000

upload battery.zip

GHqBD_1942 Yes, a lot, from my experience. A single e-sim drains much less than dual setup. Without any sim at all, you should have even better battery life. My phone can withstand a full day of heavy use with 15-20% left at the end of the day or a couple of days with very light use. This is with 24/7 VPN usage.

If you're going to reinstall through a PC, I suggest you burn a clean copy of Linux Mint/Ubuntu to a USB and boot through that and do the manual install with adb/fastboot to be in full control of the process.

Well, I already installed with Windows 11 using Brave, I'm going to see if the battery keeps draining with absolutely nothing installed. If this fails I'll try you suggestion, thanks

GHqBD_1942

Ok, the battery doesn't drains when nothing its installed, but it came back after I restored my data with my backup file, so I'll try to fix it by my own.

Is there anything I can try?

GrapheneOS

GHqBD_1942 We know there isn't a battery drain issue on fresh installs without apps installed. You can see that for yourself. You know it's caused by your apps and will need to narrow that down and identify which ones are burning a lot of power. It's best to start with anything listed by the OS as an active app which means it's running a foreground service. Open the notification drawer and check the active apps.

GrapheneOS

Marking as solved due to GHqBD_1942.

GHqBD_1942

I can't see any active apps, I'm going to try using Hali to freeze apps, but I don't know what apps are causing the draining, should I use Better Battery Stats or a similar app?

GHqBD_1942 Can you rebuild your APN profile? I had that issue after an update and found that i could only receive MMS and not send. I deleted and rebuilt my APN profile and problem solved with battery and MMS. I use a T-Mo mvno and it seems it may have been stuck on T-Mo network. Not sure if this helps but thought Id share.

GrapheneOS

GHqBD_1942 You should use the OS provided Restricted battery mode for user installed apps you don't need running in the background.

GHqBD_1942

what is a APN profile, MMS, T-Mo network? srry I'm no expert

HIghQualityH2o

GHqBD_1942 Access Point Name. It is under your SIM settings. T-Mo is just short for T-Mobile. An MVNO is just a Mobile Virtual Network Operator - a company that resells service of a major network. Some examples are like Total Wireless and Mint. You can search your carrier website and see if they provide the APN settings for their network. Mobile devices are frequently keeping in touch with their network. If they can't find it (maybe because of an APN issue) they continue to attempt sending data unnecessarily which can cause battery drain.

GHqBD_1942

I don't have a SIM yet, but I don't understand what you mean, if I get a SIM I should change some settings about the the APN?

GHqBD_1942 if you don't even have a SIM, this doesn't apply to your problem.

GrapheneOS
How can I activate it then?

GrapheneOS

GHqBD_1942 In the Settings app, it has a menu for app settings. You can also go there from the app info shortcut from long pressing on the launcher or pressing the icon in the recent app screens. There's a battery configuration menu where you can set the battery mode to Restricted for an app. This will stop the app running in the background except when it's started by another app, such as receiving an FCM push notification from sandboxed Google Play or the same thing with a UnifiedPush provider. Launching it from a launcher is the main way it happens. It delays alarms, scheduled jobs, broadcasts, etc. until the app is started by another app.
