I think I may have found the fix. I had the main power supply (130W) connected to the right hand thunderbolt port, and the instructions for connecting the external monitor suggest using the left hand side ports which have priority. So I plugged the PSU to the left hand side port now. It seems that for power the left hand side ports also have priority. Fingers crossed.
Have the same issue with the battery drain under heavy load. The power adapter does not supply 130W even if connected to the left side ports. Tested with a power meter.
My issue is when I have the left most rear cable connected to an LG Usbc90W monitor, and the 130 power supply on Right rear port. I tried putting power on the left port like you mentioned but it did not work. The official dell documentation https://dl.dell.com/topicspdf/xps-17-9710-laptop_setup-guide_en-us.pdf recommends the power on the right side on page 7. I did the direct NVDA bios setting as in that document, and it made no change. However, when I put the usbc cable on the left FRONT usb port, all of a sudden it started working. The document does list priority on the left ports, but I have no explanation for why the laptop charges properly when my external monitor is on the left forward port (closer to the user). The extra USBA ports on the external monitor work on the LG 34WN650-W UltraWide Monitor 34" which is the main reason why I want to use usbc on the monitor. I am guessing that if i want to connect a third monitor I would have to use usbc-display port instead of usbc.
by the way, in the above report, charging SUSPENDED at 16:39 to 17:28 was when I had the monitor usbc cable in the rear left port. At 17:31 I had the monitor connected to the left front port. Right now I'm back up to 96 percent, waiting to see what happens at 100 percent. (19:07)
Please note the Design vs Current Capacity mWh at the top of the report.... and be advised that the battery warranty is pretty limited on Dell machines. (I believe just 2 years).
Also, I want to say thanks for logging this question, because while researching it I found out that my Direct Graphics Controller Direct Output mode is Disabled by default. So after switching it on, I noticed a MAJOR improvement in Lightroom Reviewing multiple photos on the external monitor. Even reviewing the JPG after export on the external monitor was at least 3 x faster. This is something that needs to be communicated in a better fashion to users of dell machines. (it's now almost as fast as my 3 year old macbook pro for Adobe Lightroom purposes).
try the monitor to the left front port instead of the left rear port and let me know if that makes a difference. My issue was with an LG monitor that was not charging at all. (Not a 100-94 percent issue like yours). However, I read that the Mac laptops have changed the way it charges so that it does not charge to exactly 100 percent to increase the lifespan of the battery. Maybe the Dell BIOS updates perform similar tasks.
What you can do is create a battery report, and it will log the battery percentage and show you in a table so that you will know what is going on.
To do this:
1. in the search window type cmd - dont open directly - RIGHT CLICK and choose Run as Administrator.
2. type C:\windows\system32\powercfg /batteryreport /output c:\battery_report.html.
3. It would say Battery Life report saved to afile path c:\battery_report.html. Open that file with your browser and read the data... it should look like below.

Information about each currently installed battery
I just had my laptop shutdown *again* in the middle of a teleconference. This is my second XPS 9710 (returned first due to failure). Both have had this issue. All instructions regarding connections to power and monitor have been followed as per https://dl.dell.com/topicspdf/xps-17-9710-laptop_setup-guide_en-us.pdf. Still, often, when I'm using the monitor (plugged in on left while power is plugged in on right), the system slowly drains the battery and it eventually just dies during use.
After finding this thread, I will try using the left front USB for the monitor but, to be honest, this ranks up there with Steve Jobs saying "You're holding it wrong" with the historic iPhone issues. This is just negligent design and I hope it can be fixed with a future firmware update.

Let me know if the solution you mentioned worked.
