Hi all,

Just wanted to ask the question: What kind of alien space tech programming have you done to GrapheneOS???

My Pixel 8 Pro has gone for 4 days, no charge and I still have 51% left, currently only using 10% per day, this is new and wasn't this good before.

I don't use the phone heavily, but I do take the odd 3 or 4 scam calls a day just to insult them, and the odd text message, banking app etc, but even still, I have an iPhone Pro Max that will drop over 60% in a working day doing nothing.

In about three or four days I will charge the phone again, and fully log the exact battery run time, but currently, the standby time is amazing.

    NXG-3D GrapheneOS isn't bloated unlike iOS or stock OSs. It's very minimal by default and you have to install the apps you want yourself.

      Yes I know, I've using it for 7 months now, and I have it loaded with apps, I'm just surprised over the past few updates on how good the battery has gotten, they have weaved some magic somewhere, since I posted this, I have dropped by 1% battery

      NXG-3D I've noticed this too on a minimal install. Battery life on a 6a is stellar.

        Not realistic for most, but I've noticed that not having the SIM saves a bunch of battery.

          Your battery did last four days?!
          My Pixel 7 consumes 40-50% battery from 7am to 22pm just by laying on the table.
          It already did right after I got my new phone and installed it.
          I'm fine with it as it lasts one day without problem - more would be better but I can charge at night anyway.

          Can anyone confirm that battery durability?

            Battery consumption is influenced by many factors, such as which apps are installed, how they are configured, and how they are used, how strong a cellular signal one receives, likewise Wi-Fi.

              Just passed 48h since I fully charged my phone. 5h sot and 34% left. I would have a lot more juice left but I do use newpipe to listen to podcasts.
              Battery life is surprisingly great.

              My phone is now dropped by 6% since my last post, that's 12hrs and I have plenty of apps installed, also connected to a Samsung Watch via Bluetooth and connected to Wifi 6.

              But I'm obsessed with disabling notifications, so only phone calls, txt's and system updates can produce notifications.

              This is actually day 6, and I'm on 35% left, I will post again after a full 12hr day.

              The phone is just stellar for standby time, my Wife has the latest iPhone Pro Max, and that wont even make 2 days of light use.

              I never used this Phone at all with stock OS, but I will guess it didn't last more than 2 days with light use.

                NXG-3D If you don't use sandboxed Google Play which has to run in the background to deliver notifications etc., or something like Signal which would either use Google Play or its own implementation for notifications, it explains why your device has this kind of battery life.

                People who report "bad" battery life almost always have a bunch of stuff always running that results in that kind of battery life.

                GrapheneOS in the way you're using it is going to have much better battery life than stock as there isn't a bunch of services running by default, but you can install plenty to bring it on par with stock, and even beyond that, e.g. by using multiple apps with their own notification systems, which would mean each of them has to run in the background separately etc.

                  I do use Signal for my calls and messages, as its currently the only way to communicate with iPhones properly and its enabled for notifications, I also do have the Google backend enabled, as I use Android Auto with Waze and other things like my YouTube channel, but again, I disable all but essential notifications as I hate (with a passion) the dam things.

                  My battery was terrible before due to the Bluetooth issues with my Samsung Watch, but since that was all resolved, the battery has gotten better and better.

                  I also run Immich and Syncthing, in the background, so my photos and videos are automatically sent to my Storage Array, but those are 100% local only, Google BS, and again, no notifications.

                    NXG-3D If you're running sandboxed Google Play and get this kind of battery life, that's pretty impressive. :)

                    I have a Pixel 6 that's a few years old now, (about 350 charge cycles in) and it holds up quite well. I'm at around 60-65% at the end of the day if I don't use it extensively. I could likely go for 2 days without charging, but I prefer to top it up at night instead.

                    I imagine people rocking newer and more efficient phones are much more likely to get better battery life, as you are :)

                        And you see, this is mostly just debloated android.

                        GrapheneOS does a lot of things that should actually make it slower than AOSP (or less customized forks like LineageOS, iodeOS, CalyxOS, etc.) because it implements a lot of security mechanisms.

                        hardened_malloc is noticeably slower, even though it seems to be pretty optimized on GrapheneOS. On desktop Linux it slows down some things quite a lot.

                        Secure app spawning doesnt (?) use zygote to fork processes, so they share no (or less?) RAM content, but this increases RAM consumption.

                        Many apps are way more minimal though, but this depends on if you keep them. Still, also many FOSS alternative apps (Gallery, Filemanager) are way faster than the Google Apps. The preinstalled keyboard and camera are also really fast and small.

                        Nowadays you can roughly say: if an app is pretty small while having many features, it is well written.

                        Especially in the proprietary space, things are going crazy. It is pretty normal for random store, shopping, "social media" etc apps to be over 400MB! While these are mostly webapps.

                        Running webapps as much as possible is a very good idea. I have not tested, but assume Vanadium is also more easy on batterylife than Firefox mobile (Mull) or others.

                        You can also use the accessibility settings and disable animations, which may save a bit. On pixel phones, using a dark theme also helps a ton with energy consumption, due to the OLED display.

                        You can always enable Airplane mode or even disable the SIM from Settings > Network & internet > SIMs > [Carrier name] > Use this SIM, toggle off.

                              Every time I go backpacking I switch to airplane mode, because most of the time I don't even get signal. If I do just a few photos for whole day I will loose about 5% battery. I stopped taking power bank with me.

                                  I noticed the improvement with battery as well. My phone usually lasts around 3 days. Last time I checked it had exactly 10h screen on time (and 1% to spare:-) )
                                  I installed circa 20-25 apps and I do not have many of them running in background. With Google play services the battery lasts for me almost the same and sometimes better than without them.

                                  For me the problem with battery without using Play services caused Signal. I even tried Molly, but it didn't help. With Play services this drain never happened.
                                  The second thing that affected battery in my case was 5G. I move a lot between places where there is a weak 5G signal and it affected battery strongly. I switched to LTE and since then the battery is as I described above.
                                  I have a 6a.

                                    Okay so she's getting low now, 23%, will probably be good for another night, then I will charge her up :)

                                    I am down to 50% and I charged three days ago. Depending on my use I get usually around 3-4 days of use out of my phone. Sometimes a little more sometimes a little less. Its really great :-)
