Better Battery Stats - no access to battery stats

androidin

Hi, I am struggling with battery life and want to search for the culprit. Therefore I tried to get better battery life running and executed the necessary adb commands. They were all accepted but as soon as the battery statistic is read the access is refused. I am wondering if what I can do to overcome this. Please see the screenshot what's going on in detail:

Stuff is in a foreign language I can't read. But then again, why are adb commands needed when you can just read the battery stats that come with the system? Or is there any specifics you couldn't get?

To second that opinion I also find

Settings-Battery-Battery Usage
and
Settings-System-Developer Options-Running Services

enough of an indicator what eats up memory/battery.

Hi first of all, I installed better battery stats after I realized the battery draw. Better battery stats displays the number of wakelocks if the screen is off. I would like to see this directly baked in GrapheneOS. Saying that I assume that there is some problem with push, namely that a lot of apps implement their own push instead of using the firebase from Google. I personally have:
Fairmail
WhatsApp
Threema Libre
Ntfy
Garmin connect
FotMob

Those apps are sending notifications on a regular basis.

androidin I've read that whatsapp POLLS for notifications and consequently eats battery really really badly.

Fairemail could poll, if you set it up wrong using POP3 protocol instead of IMAP. If you set it up correctly, it will use IMAP IDLE for message pushing, which will have virtually zero battery impact.

I use BBS for this too. I'll wake up in the morning to a 5%-7% batter drain and it's all attributed to idle. It was various app wakelocks that were causing it and BBS helped to isolate it.

BTW, if you want to use BBS, some permissions are needed:
adb -d shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS
adb -d shell pm grant com.asksven.betterbatterystats android.permission.DUMP
adb -d shell pm grant com.asksven.betterbatterystats android.permission.PACKAGE_USAGE_STATS

adb -d shell settings put global hidden_api_policy 1

Kottonballs that's all about in this thread. How did you get it running on GrapheneOS? I set all those permissions via adb but it don't work.

intelligence OK, my Fairmail fast synchronization setting was set to IMAP as well as pop3. Is it this ring what you mean? Apart from that, I set when to get messages to always. I can't durex set imap. Therefore I am not sure, which setting you mean...

androidin

intelligence can we influence somehow the polling frequency of WhatsApp? Apart from that I would like to read the source which claims this. Do you have the link? Because only of WhatsApp I had to activate play services network capabilities. And play services kicks in with it's firebase solution based on push...

androidin was set to IMAP as well as pop3.

I presume that you mean IMAP for one account, and POP3 for another, since an email account can be one or the other. You should see if its possible to switch the POP3 account to use IMAP instead, this will save a lot of battery.

No idea. I don't use it. I believe it was somewhere in this forum that I read it.

Hi again, for some reasons better battery stats is working now. I unplugged my phone shortly before I went to bed but here is my first result:
kernel wake locks
partial wakelocks

Partial wake locks are as expected I would say and nothing to worry about. Can someone interpret the kernel wake locks especially from the power manager?

androidin

intelligence the email account is set to IMAP. But for the fast synchronization one can choose both pop and IMAP.
