Yeah, I have a nephew who has been praising Graphene OS, and him and I are like minded to go more private oriented then the rest of my family. And he has been telling me how stupidly awesome his battery life is.

That being said, I just rebooted the phone after not finding out exactly what was causing the wakelock and noticed that now my device states (at is current usage) 14 hours left on usage (which is still not as what stock was). I was running Accubattery prior to the reboot, never had any issues with deep sleep with that, but uninstalled it anyways.

Forgot to mention, I do run orbot (not on vpn mode) and nordvpn together. But will still test some more and report back. I really do appreciate your time and feedback with my issue, thank you.

      ozzmanj1 A good way to test for what's causing the problem is to start off with a factory reset and then gradually add different software until you find what is causing the trouble.

          Sounds good, if battery does not improve by this weekend, I will factory reset and re-apply each app individually.

          • Off hand, is there a GrapheneOS forum app (like how XDA has an app to you), just curious.

          Thank you

            Have you checked the battery draining apps in the dedicated settings menu ?

              I did, it was showing CPU as taking up upwards of 16% battery usage when the phone was sitting next to my bed at night. I think I may have found the issue, but am still going to give it a couple more days to verify. Will report back, just in case.

                Okay, so update. I have gone in and restricted pretty much any and all apps that I did not feel needed to be optimized, cleaned up permissions to what I felt was needed. I read on another site with Graphene that using googles Device Health (battery manager) helped improve the phones Idle battery use. I have gone in and done all sorts of things and honestly I am not sure if its getting, it almost feels like it is getting worse. As I cannot attach a photo, here are links to the batter life while I was asleep.

                Last night, went to bed, battery at 78%

                This morning, 61%

                https://photos.google.com/share/AF1QipNMGGlcw4LRqzM4qCu0yGTkNMccITlRdissJA2byYNW-Rrh45sMQyNP7b_GqYQHiQ?key=aDlYZ2xDVDlxcy1ldk1MNmFrejFlczR6b2RpYmVR

                Should I factory reset? I am consistently seeing Phone Idle taken up a lot of battery as well as System CPU ( I have tried various wakelock apps to determine what may be causing this to no avail. Could this be because of sandboxed Google stuff (play services, framework and store)?

                I would really rather not factory unless I absolutely have to. Any assistance or guidance is greatly appreciated, thank you in advance.

                  Have you disabled 5g?

                  ozzmanj1 I don't have much in the way of solutions unfortunately. It's entirely possible you've got yourself a lemon, and either the battery health is poor, or some hardware component could be drawing excess power; there are many possible factors and I really don't know.

                  I really just wanted to say that I don't do any additional tweaking of battery optimization other than setting some apps to unrestricted, and I am not seeing anywhere near the idle battery discharge that you are. I have several apps running as background services (VPN, K9 mail, Signal, etc.) and if I don't use my phone much during the day, my battery will still have about 80% capacity remaining when I go to bed.

                  In case it matters, my carrier is LTE-only.

                    I should have mentioned, I have used Accubattery in the past and it reads (still as of last week) that my battery is 5011mah and healthy. When I was on stock, I would get upwards of 6-8 hours screen on time. Perhaps later this week when I have time, I will factory reset and reflash GrapheneOS and see how it goes. But I know my battery is not the issue.

                      ozzmanj1 I will factory reset and reflash GrapheneOS and see how it goes.

                      A lot off people complain about battery drain with GOS by comparing with their old phone. I don't think you will see a real difference.

                        Have you tried turning off the mobile data despite the phone being connected to WiFi?

                        For me that makes difference. I even went and switched off "Mobile data always active" using Developer options. I think this is similar to the "Adaptive Connection" of the stock OS which I can't find in GOS settings.

                          Hi, in my case I had extreme battery drain when I disabled "Enable native code debugging" in the Security Settings.
                          Some apps stopped working and maybe this was the reason.
                          Science I reenabled code debugging I have great battery experiences.
                          May give it a try...

                            Oggyo apologies on late repy. I did do this. Still did not change anything. After a fresh install a week ago, I had good battery for about 3 days then it went to garbage again. Last night I went to bed and had 78%, woke up to 32%. System CPU was eating up around 22-24% overnight.

                                t_lo This is enabled and I have never touched it. But yeah, battery drain has been pretty sporadic. Last night my phone dropped about 40-45% overnight while I was asleep. System CPU was eating up about 20-25% overnight, with no idea why or what it could be.

                                    ozzmanj1 That is definitely not normal. I would suspect a bad app or that something is going on with your hardware or carrier.

                                        mythodical I would suspect a bad app

                                        My bet would also be that; hardware issue is possible but waaaay down the list of possibilities

                                        ozzmanj1 as inconvenient as it may be, you got to start removing or disabling downloaded apps one by one few days apart to find the culprit

                                              f13a-6c3a I have been skimming my apps. Just to re-iterate, prior to switching to Graphene I was getting easily all day with the same apps (mostly) installed. After I reinstalled Graphene a week ago (after initially installing it the week prior but reinstalled due to bad battery life). After the install again of Graphene last week, I had awesome battery for about 2 days, then it drastically went down.

                                              I have a family member who has been using Graphene and he uses Google apps on a second profile, he believes it may be since I am using sandboxed G stuff that it could be the culprit, but I do not really see how.

                                              Also, just to mention, I have gone in about changed battery to restricted on all apps I do not feel I need to be optimized, and even changed background to no background data access, only if/when I fire up the app.
