Sounds like it's quite normal unfortunately, my battery drains just looking at the phone. I've not actually used the camera yet but I'm now dreading it. I've gone back to my Note 8 and the display is brighter and better. The battery life is better too and it only has a 3300mah battery.
Only thing that will eventually force Samsung to take notice is if everybody returns their handsets.
At least we have 28 days to evaluate. It took a while to set up but I will try a factory reset without restoring settings to see if that makes a difference.
Samsung don't even respond to these forums so we're wasting our breath here I think.
I have noticed this too, cannot get a full day out of the Now 20 Ultra whereas I could with the Note 10 Plus, going to give it a few more days but might have to send it back!
Defiantly I have noticed the battery drains alot quickly and gets warm. I have also expressed that Samsung should of used the SD865+ instead of the Exynos processor and if it's not good enough for South Korea Samsung's home country then it's not good enough for us as well. Sometimes wonder if it would be a note 7 and explode. On a work day when in the office my phone idles but gets its regular notifications. I use it during lunch breaks and 15mins top on a game. Evenings it can vary depending on if I game on my PC or go out. I set the settings to the exact same as my note 10 and well my note 10 I got 2 days if I was in. I got one day with this phone.
Most youtube reviews I saw were of snap dragon but there was one which did a full battery drain tests and those test comprised of running youtube straight, regular browsing and gaming and all those were tested the Exynos versions of the Note 20Ultra, S20 ultra, Note 10+ and the apple iPhone and you can guess which phone died first, yep you guessed it the note 20 ultra died first on all tests without fail and with a bit of a margin between it and the note 10+ and the note 10+ plus would of been a year old so battery would of had some performance would of been degraded as well I suspect.
I love the new screen and I like the new cameras and the new features but yeah the heat and the battery drain is a major issue for the phone. All my other notes lasted me alot longer then a day brand new and it's something that needs fixing. I even suggested a replacement program and that have a snap dragon variant at least to replace the Exynos version.
I have the 865+ and the battery is horrendous. This phone is beautiful and I love how it runs. Still kinda odd the screen resolution seems a bit weak compared to previous models but it still looks amazing. If they could figure this battery out then this phone would be PERFECT.
Its possible we got lemons as well.
