My smartphone detailes.
1. Note 9 SM-N960F, Android 10 (One UI 2.0).
2. Purchased on on November 19th 2018.
3. I always charge the phone with original samsung charger.
4. 99.9% of my phone apps are in sleep mode.
Almost immediately after I updated my note 9 to Android 10 - the battery started to drain very fast.
I checked my battery life with Samsung members app, which gave me A message that I should visit Samsung technical service represantative.
Please let me know if you experience this issue and if you discovered what cause to it.
Thanks in advance!
First, thank you for the response.
Second, my note 9 battery life WITH OR WITHOUT gps, wifi was certanly better and longer in the previous Android version.
The battery drain is appear even in standby mode.
In addition, I'v noticed that there are more people with note 9 or with note 10 that experience the same issue.

I am having same problem. But after going over various apps have managed to bring down the drain and dropped the display mode down to basic HD at moment. As you sid. Its only since last update. It also affects note10. Not good as its happed before. Have to waite for sammy to get there act togeather.
I have different issue seems like its a bug or software problem I don't know.
> When my battery is around 30% and I plugged for charging it drains while in charging. It goes to 15 wihtin seconds then 5 and 1%. Then it starts to charge. There is no fault in my battery. My battery life is good. According to screen time and application usage shown in battery usage of Samsung device health. It 100% good but this is the issue with the ONE UI, I believe.
I contacted support center and they have suggested me to visit service center. But I don't know how are they gonna fix it. I am going to reset my phone to factory reset to see if there's any software issue or hardware.
