i left grapheneos and shifted back to stock os
battery efficient no drain at all
i would prefer battery over privacy
coz if it is draining too much, then phone becomes useless

I did some tests the past couple of days/nights and can say the only times when the A14 overnight battery drain is close to A13 is when placing the phone in airplane mode. No other changes (location, home WiFi AP configuration, etc.) recently. I'm with Graphene OS's latest update. Tried disabling some IM apps (WhatsApp, Viber) - not much difference.

To summarize - with A14:

  • 3% overnight drain with airplane mode on.
  • 3-5% overnight drain with WiFi off, mobile data off.
  • 10-15% overnight drain with WiFi on, mobile data off.

I was thinking about resetting the WiFi but a bit reluctant because it is tight with the Bluetooth which I'm not ready for now (Settings > System > Reset options > Reset Bluetooth and Wi-Fi).

    I will never ever complain about battery issues for the security and privacy benefits GrapheneOS brings. The rest is a human error.

      I'm not complaining, I'm comparing GOS on A13 builds vs GOS on A14 builds :)

      @NightSky, I know your reply is not directly to me, but I just to point out I'm on LTE-only mode.

        Oggyo OP waa using 2 apps (Facebook & Whatsapp) by Meta.

        Oggyo Same here. Just mentioning it, i know there is no reasonable solution. It was good in the first weeks of A14 release but the last week is awful. It is probably related to whatsapp, but it was last updated on 6th november. I always go to sleep with 100% battery, waking up after 6-7 hours with 50-55% now. It used to be 85%. The drain continues during the day. Unfortunately i cannot get rid of whatsapp because of school and work.

          Can you turn WhatsApp off while you're asleep?

          Is this with 5G on or off?

          5G is on.
          re: turn WhatsApp off -i can, if don't forget, and more important i should not forget to turn it back on in the morning.

          Maybe some automation that disables apps by time would help... But better would be if I could set whatsapp background process priority... but this would require root I guess.

          I thought of bridging whatsapp with matrix.org, and use then only the element.io client which works good - it's possible - but requires additional pc to run all the time, not really a solution.

            andrej567 5G is on.

            Maybe try turning it off for a few days to see if it makes a difference?

              de0u I can do that on saturday - sunday, for longer time to get proper data.
              In the past i used the BBS app - better battery stats to find out which app that is draining the battery but it does not work on android 14.

              I'll turn off whatsapp now. The second biggest drainer is the Launcher, according to battery usage. That's interesting.

              de0u I had 5G off in the past, the battery drain was 1.5x higher.

              In the summer, abroad, if I had 4G on, the battery drain was sometimes going to extremes, 20-30% per hour, with 5G it was 2%. So I left 5G on, september, october were fine, spending about 12% of battery per night idling. Not sure what changed. I did not add any apps or alter any settings. Just the automatic updates happened

                Thanks for the report!

                Over time, as carriers roll 5G out further, that may become more common. Everybody's situation is different (and subject to change), so experimenting makes sense.

                just to add
                on stock os, i am getting 5 to 8 hours of screen on time with 5g and facebook
                with grapheneos, screen on time was 2 hours at max

                  kingw try running a fresh GrapheneOS vs fresh stock with no apps installed for couple of days before judging. Problem is likely in your app or settings setup, network instability or multiple profile use to name a few.

                  kingw Not apples to apples, but close. My 6 with stock Android 14 gets better battery life than my 6a with GOS. Probably 30-35% better. That being said, I am by no means a power user and get a full day out of my GOS 6a, so no complaints.

                  My 7a is having horrible battery life as well (drops ~25% overnight doing "nothing"). I'm on airplane mode+wifi 95% of the time, too. The 6a I have, setup pretty much identically (same apps running in the background, airplane mode+wifi) gets amazing battery life (drops maybe 5% at night). On the 7a, for whatever reason, "Mobile Network" is still consuming 10-20% overnight, even in airplane mode. I'm still trying to narrow it down to try to figure out why.

                  Is there a different wifi chip on the 7a vs. 6a? What else changed from the 6a to the 7a that could be a cause I could try to eliminate?

                  One thing I did find is that even in Airplane mode, the 7a has "Mobile Radio Power" enabled when I check in 4636, which was surprising (I thought airplane mode was supposed to disable all radios (unless you manually enable Wifi/Bluetooth). I disabled it, but it turns itself back on after a little bit. However, it seems the 6a experiences the same thing, so doubtful that's the culprit.

                  I'm still fighting this -- overnight it dropped from 100% to 72%. I was on airplane mode the entire time with Wifi on, Voice over Wifi enabled, bluetooth disabled. 0 min SOT. System usage has Mobile network reported to have used ~60% of the battery each 2 hour time block (which doesn't make sense since it dropped 28% overnight). App usage is all <1%. I tried resetting mobile network settings, but that didn't help. I don't understand why "Mobile network" is using anything at all since I'm in airplane mode the entire time.
