I think it is expected to drain a bit more. I noticed RAM usage is slightly increased. Moreover, there is more fluid animation on One UI 7.0.
On the other hand, our batteries are ageing, more than 2 years, so will degrade slowly.
I got Care + which ended last month, I didn't go for the battery change as I feel it is really mafan. Conflicting reports from different service centres said, need to put there for many hours and some said need to do factory reset. I'm lazy to do a reset as need to restore a lor things, such as singpass, banks, crypto account, social, shopping apps.
According to AccuBattery Pro app, my battery level is at 86% / 4,296 mAh. Samsung Members app shows it's Good. Settings information shows Typical.
