Even with recent beta update, my battery still drains fast. It's way worst than before beta. I think I will wait for the post beta version. Trying to figure out how to take beta off, if possible.
That was my issue but after thr 3rd update things have stabilized a lot. Now is giving me about 45mins to 1 hour of extra screen time, for the record my Fold3 never had good battery life before the Beta.
I haven't had this issue. I keep my phone in "power saving mode" and allow background data in apps settings for the most important apps like emails or Samsung health for fitness tracking. Have you tried turning that on?
