i returned 2 note 20 ultra units and got a S20+. First unit was pre order from samsung had the camera fail on me and heating issues while on wireless charger and poor battery life. Second one from Best Buy had bad battery life and echo issues when using speakerphone. I tried all troubleshooting steps, letting the battery learn my patterns for about 10 days made no difference. The background drain is really bad on this version. Also i thought it was the adaptive refresh rate so switched to 60 and FHD and still bad battery life. My S20plus with the same battery and with 120hz refresh rate locked at FHD gives me an entire day of usage with approx 5 to 6 hours Screen on time. I traded in my Note10 plus at Bestbuy and really regret that now. This Note20 Ultra is not a power user phone from the past if you are someone who needs it for real work. Try using webex zoom or microsoft teams and see that battery just die on you.
