So I now know power saving mode UI is so different to the power saving mode Android 10 and UI 2.0
Since on Android 11. UI 3.0 The power saving mode options is very different.
My understanding is the whole idea of power saving mode go save juice not drain the phone.
One UI 3.0 has been a disaster in terms of the battery life.
Yes there are excellent features but why is it that S10+ users or S10 series have to be affected by this stupidity of Samsung UI new update???
