    Has anyone else been experiencing poor battery performance since the Android 8.0 Oreo update? My phone battery used to last a full day easily with moderate use, but now I have to charge it during the day otherwise it's running too low by the evening. Before the update I had recently formatted my phone, and I'm still in the process of getting apps set up again - in short, my usage isn't as high as it used to be but the battery performance is worse, and I'm pretty sure this coincided with the Oreo update.

    Anyone else experiencing these problems with an Android phone? I guess it could be a Samsung only problem, but it would be useful to know if anyone else has had issues.

    You wouldn't be the first to mention this. There are some tweaks you can do, like turning off bluetooth scanning in location settings.

    Is something keeping it awake? I take it there are no clues in the battery stats? You could try installing something like GSam Battery stats and see it if show up the culprit.

    Do you use the Facebook app?

    I'm currently on the Android P beta on my Pixel 2XL, the battery is great! To my surprise!

    That's a good point re GSam, I used to use it before I formatted my phone. Just downloaded it so we'll see what it says...

    I have Bluetooth always on, it can't sync with my FitBit otherwise. This does affect the battery, but it was always on before I did the format and battery life was ok then. I don't use Facebook either.

    Interesting about the Android P beta being better for battery life! I'm really starting to go off Samsung, it's always so behind. Not sure what I'd go for next though!

    Tbh, the battery on my Pixel has always been good back on Nougat and Oreo, I was just expecting the beta to be less optimised as they usually are!

    One thing to note, make sure something like one of the Google sync services hasn't got 'stuck' in the background and is keeping the phone awake, I've had that happen to me a few times on my Samsung tablet, not sure what causes it though...

    Turns out I can't used the GSam app to tell me which apps are sucking up power because my S7 is a non-root device. I'm seeing what I can do via the Samsung power monitoring, although it gives less data than the GSam app unfortunately. Why is nothing in life ever easy?! :rolleyes:

    My S7 is still on 7.0, but friends that are on 8.0 haven't said they have any issues yet.

    I hadn't realised you had an S7 too @EvanDavis! Are you planning on upgrading to Oreo any time soon? You'll have to let me know how you get on if you do.

    It used to run fine on mine too and gave me a full breakdown of usage by each app. I wonder if it's because you're on an older version of Android?

    I'll upgrade as soon as it is available for mine. I only just updated to 7.0 a couple of days ago. Last year while in South Africa I did a factory reset on my phone and now my updates seem to be out of sync with UK updates.
