Not being a heavy phone user, for a long time I could recharge my phone once in a 6 to 7 days.
Now for some weeks the batteries empties much faster.
I did a test and charged my phone to 96 %, disabled Signal in the Apps settings and left the phone for a day.
In 1 day and 16 hours the battery was 69%, not having used the phone.

What can I do?

    Pixel4XL_John For comparison purposes, maybe do it again but with the cellular modem disabled?

    Pixel4XL_John I have a 6a, so direct comparison is not possible. That seems maybe high? What does Android battery usage say consumed the most energy?

    That seems pretty fine to me. The cellular radio must consume power to remain connected to the cellular network. Depending on signal conditions, it could use more or less. 20% (96 - 76 = 20, not 25) in 1 day and 16 hours seems pretty good to me. That translates to 8 days and 8 hours.

    And considering that that is a 4xl, its also getting pretty old as far as lithium batteries are concerned, so I wouldn't expect the battery to have anywhere close to its original capacity.

    I've been analyzing with Better Battery Stats.
    One thing that stands out is the many wake locks from glink-native-modem

    I'll start a new post for this issue.
