Sivyyeahh me too bro . what happend on this, should go back to a12?
I can confirm my phone also has substantial battery drain since updating to WW_33.0804.2060.73. non rooted phone. The battery under Android 12 used to last overnight and until approx mid day next day with light/moderate use (no gaming) whereas now it runs out by the evening. In addition, after reaching 3-5% it shuts down completely.
