I have the A52s and upgraded my work phone to A54. A54 is giving me 4.5 to 5 hours SOT. Only social media and web browsing. Doesn’t even show the underlying cause.
The only reason I upgraded was it was from my workplace and the A52s had many scratches on the screen.
The screen is not as smooth (apps lag). Scroll is not as smooth. I hate the phone to my guts
FML.
A52s has the worse haptics and battery is pretty average too, even then it would do 5-6h of SOT
A54 has none of these issues and I’m getting around 8h SOT with all day standby with intermittent hotspot usage. The best i could get was close to 11h straight out of the box.
You may need to optimize your phone first, Check out Jimmy is Promo youtube channel there are around 20-25 OneUI settings that drain the battery - you have to disable most (if not all) of these to get the best out of your phone.
