Battery drain after Android 8.0 Xperia x update

[JahCre]

What can't I do to prevent battery drain? Just update to android 8.0

There is an option within gsam battery app to grant additional privileges, that cannot be given as regular permissions, but via adb . You might want to check that.

Now, I'm aware of your lack of interest in X , but this could be useful for any phone you move to.

So look at it that way, a general knowledge gained for a minute's work.  

And to some point I also agree with your stance that regular user shouldn't pay that much attention and troubleshoot, but with battery, quite a lot of time it's on user and issue, or rogue app more specific.

I found the culprit:auto sync data. And the battery monitor app confirms it. Don't know how the update messed up with the settings but I guess I have to turn the auto sync off for now.

After the new update of my software, the battery is discharging quickly .... Why?

Après la nouvelle mise à jour de mon logiciel, la batterie se décharge rapidement.... Pourquoi?

Salve, da quando ho aggiornato il telefono a oreo 8 il mio smartphone si scarica velocemente. È un problema solo mio? Se no, come  avete risolto? 

Hello, since I updated the phone at 8 o'clock my smartphone is quickly downloaded. Is this a problem only mine? If not, how did you solve it?

You might want to look here and then go up a few posts here.

and then let your device settle some time and see how it behaves.

Two things:

- No, you're not alone. Your question has been posted and answered manifold. A search on the forum might have answered your question.

 Anyone has figured out any fix for the masssive battery drain of Xperia X which updated from Nougat to Oreo? I have been experiencing fast draining of battery since i updated to Oreo. Full-charged phone only lasts 4-5 hours.

Its not widespread as one would think. A lot of us have no unusual drain at all.

Try with previous advices given across board, Strampke linked a few above.

Maybe it's an app which is not adequately updated for Oreo. Try safe mode and see if there is such drain. Although I hate to troubleshoot battery in safe mode, makes no sense, but still, might confirm.
