    Hi,
    I recently got updated to Android 12 on my S20 5G and I have noticed that the battery life has deteriorated fairly substantially.

    Anyone else??

    I always do before updating and immediately after updating.
    And I have done it an extra couple of times since.


    I also actually think the battery performance is getting progressively worse since the update.

    It's still able to achieve 6h sot but it's barely making it through a working day.

    It's losing 7 - 8% overnight just sitting on the bedside locker.

    It's not bad for 2 year old device but maybe factory reset to see if it can improve?

    But it was performing much better before the update......I would expect the first update will be to fix this issue......there seems to quite a bit of it on the WWW



    Also, I obviously meant Android 13

    I think samsung do this with every version of any phone.
    By the way, when i make the phone 5g without power saving,
    The battery gets drained fast.

    Cheers

    I don't have a 5G account and I have 5G switched off in the network settings.

    I do use power saving.

    My battery isn't the greatest on the 20fe anymore, since upgrading to 12, even though it's healthy. BUT, I have outlook, gmail, social media apps, MS Teams, etc. all pushing notifications so I expect it to take a hit. Plus I have 5G turned on, high refresh rate, etc. All adds up when you think about it.
