I have terrible battery life since the initial stable channel release of Android 14 on pixel 6a. 1h = 10% down.

Despite the announcement that battery stats would be working, I don't have any.

I also noticed that the screen timeoff is often not working. The screen stays on until I switch it off via button. Rebooting the phone temporarily restores the feature. But it can return any time.

None of the issue was present on Android 13.

Currently installed version 20231011
I am using sandboxed Google Play Services.

Is it required to factory reset the phone after each major release?

    Techtrest

    I am not aware of other people with this issue. I also am not experiencing any change to my phone's battery life. It might be due to an app that wasn't updated for Android 14 and you might continue to have the same issue even if you do a factory reset.

    I'd suggest checking which apps are running in the background by pulling down the notification shade, then again so you can see the quick settings tiles. At the bottom of the screen, you'll see a circular icon with a number in it. Tap that, and a window will pop up listing apps running in the background. You can try stopping different apps and see if stopping them fixes your problem.

        I have phenomenal battery after installing 14. I am having the same problem with the battery stats. It's just blank after multiple full charges and reboots. This is after 7 hours of running the device.

        Not specific to GOS neither Android 14, however, by following few simple steps in below video I significantly improved my phone Pixel 7 batter live:

        ps.
        restart phone once you are happy with your changes. Potentially you will see high or same battery consumption after 1-2 days, then should be much better.

        I believe other8026 was right. I found an app that heavily drained the battery. Battery life looks much better now. It was difficult to spot since the battery stats were off. Thx for the swift replys. :)

            If you can say which app, the information may help other users.

                de0u it's something local. I am ordering my diet via this app. Nothing to worry about. ;)

                    Techtrest Thanks for reporting back!

                    If you move that app to its own profile, you can suspend that profile and incur no battery cost.

                      Rather than starting a new battery thread, can anyone answer the following? Usually during the night i would see consistently around 5-7% battery drain, last night i had 0% drain and would love to know why. Phone always has same set up etc.

                      Hello,

                      I have noticed the same things as OP (battery drain when barely used and screen time-off often not working), except for the battery usage statistics that I do have. All this since the upgrade from Android 13 to 14 (I currently am on the latest stable release as of today -> UP1A.231005.007.2023102300).
                      I force stopped all the apps that were running in the background, but it didn't change anything.
                      I attach 2 screenshots of the battery usage where you can see that in half a day I lost almost half the battery with barely any usage (when with Android 13 the battery would last between 2 and 3 days with average usage).
                      In the first screenshot, the usage by apps shows that the launcher consumed the most then messaging and finally the phone (these being the defaults apps that come with GrapheneOS).
                      In the second screenshot, the usage by systems shows that the WiFi consumed the most (54% for less than a min of usage!?), then the CPU with 17% and the System (IDLE) also with 17%.
                      In my opinion, there is something wrong here with the system (no additional apps seem to drain the battery).

                      If somebody knows any way to troubleshoot this further, it would be great, as for now, the phone is hardly usable as a daily.

                      Screenshots :
                      By apps
                      By systems

                        I've noticed the same problem. Idle battery draw skyrocketed after the last update UP1A.231005.007.2023102300. Before that my Pixel7a would last at least a day or even longer. Now it doesn't even last half a day and I have to charge a few times during the day. What's going on?

                        Malakai Battery usage of launcher, message app, and phone app is very high. And other apps battery usage is normal.

                        You should set battery usage of these three apps to unrestricted, clear the storage (not cache) and restart the phone. If problem persist you can't do anything.

                            Techtrest Malakai are you using a VPN?

                            No.

                            Ram You should set battery usage of these three apps to unrestricted

                            Is there any logic behind this? As setting battery usage to unrestricted could cause the app to use more battery.
                            And btw phone and messaging are already in unrestricted mode and it can't be changed.

                                  Malakai Is there any logic behind this

                                  The logic behind this is that these three apps are system apps and 2 of them i.e. Phone & message should be always in background without killed by any task killer or Android's App battery optimisation.

                                  There is an example that suppose an app is used most of the time & and should be running in background for proper functioning. It would be better if that app should be kept in RAM so that CPU don't have to work each time to start the app. And the phone, message and launcher app is very main component of a modern smartphone. This thing always work when your phone is power on. So keeping these types of app on restricted mode make your phone to do extra work each time. That's why most of these systems app come with unrestricted mode by default. These apps always run in background so it doesn't matter that you put these apps on optimised or unrestricted. But it will affect your usage of phone when these apps is restricted.

                                  In Android 14 higher SDK app is recommended. But as I know that there Targeted SDK is lower (I may be wrong). But when you lunch these apps (phone & message) first time in Android 14, a warning is shown that app is not compatible. It also can be a reason of misbehaving. Because your launcher is consuming 20% of battery, Messaging & phone 12% & 10% respectively in interval of approx. 12 hours. It is very very high battery usage.

                                  I tried my best to explain. If you think these things are just myth or useless then ,for experiment/test, you can put your all apps to restricted mode. I made this mistake 3 months ago and thinking that if app would not run in background then my battery backup will increase but a opposite thing happened. Because everytime my device have to work hard to launch an app instead of loading it from RAM.

                                        Ram

                                        True, it makes absolutely sense to have these apps unrestricted.
                                        But as you stated yourself, they are already unrestricted by default and even if I wanted I couldn't change this.
                                        I can't quite understand what is the action that I should do to try to solve the battery drain problem I am facing?

                                        PS : My wife has a Pixel 5, also on latest stable GrapheneOS version, with the same apps installed and the same overall configuration for the system and the apps, but she is not facing this battery drain issue. Her phone lasts for more than 3 days with average usage.

                                          a month later

                                          I did some debugging on the Pixel 6a and top shows the following (click on the link to see the screenshot) :

                                          High load

                                          From what I understand the top CPU intensive processes are mainly used to provision Sim functionality.
                                          Having a look at the sim settings, I've seen that the VoLTE option was activated, but not functional (calls are still downgraded to 2G, as my provider doesn't offer 3G anymore since some time).
                                          I deactivated VoLTE and now top shows this :

                                          No load

                                          So it seems that somehow the CPU intensive processes were trying to provision VoLTE on GrapheneOS, without success, and were stuck, consuming a lot of CPU 24/7, thus the battery drain.

                                          Hopefully this could help others in the same situation.

                                            Thanks for reporting back! That may well help other users. If you are in a position to identify the carrier, that might be useful as well.

                                                Malakai That is very useful. i am not android developer and I was using 'better battery stats' app for doctoring my cellphone but the app stopped working with android 14.

                                                using the top command appears to really find something.
                                                Anybody knows about a good app showing process stats? (good means - gives results, can be ugly, no ads, i'd rather buy it).

                                                anyway this instant doctoring, ups and downs, not sure. two weeks good, then days with 30%/hr drain. I had to buy another cheap android cellphone because i could not do some work related stuff because my battery was empty at worst possible moments.. so now i am carrying two devices, on one i am with privacy, on the second of course, people at google know even how often I fart.
                                                annoyingly (is that a word?) that damn cheap moto phone lasts 6! days.. for 20% price of pixel.. uh huh
