XPS 15 7590, false battery warning

I am also having the exact same problem. My XPS 15 9570 has started giving false 1% battery remaining warnings, and as soon as I plug it in, the original battery percentage would get restored. Please help.

same problem here, same xps 15 version

I've the same problem. Has anyone solved the problem? 

Same problem for months. This needs to be addressed Dell!

I am facing exactly the same issue with my XPS 15 7590. It's only been a year since I got my laptop. Hope a solution is available soon. 

Same problem with my 7590. Dell Support remoted into my machine to try to fix it and only made it worse. The tech disabled hibernation, so instead of getting the false battery warning, the machine would simply drain itself for real overnight I re-enabled hibernation and am back where I started. I noticed the issue for the time just a couple/few weeks ago.

The problem doesn't seem to be of bios because I have not updated it as the newer bios doesn't support undervolting and I still got the same problem. It seems that this problem started at the same time with all users. Most probably it's due to some other automatic system update. Hope to get it fixed soon.

I have exactly the same problem with those fake battery warnings in XPS 15 7590, already 5 months now, a laptop purchased in less than 1 year and with a battery of excellent health.

You hibernate/sleep with full battery and then BIOS (latest firmware) reports only 1% after waking up. If you somehow manage to get into the OS, unless you plug the charger immediately for the system to get back the real percentage, the OS will forcefully shut down. Moreover, while I was idling in the BIOS with supposed 1% (in reality it was 50%), the battery was drained in less than 5 minutes.

It is clear that this issue, remaining unresolved for so many months and so many users, essentially renders the portability of the device *totally useless*, as you cannot carry it with you anymore: your laptop is just another desktop.

Super frustrating if you contemplate the amount of money this model costs.

I've noticed what might be a pattern: The issue seems to presents itself only when my battery charge is below about 40%. When my battery is charged or nearly charged, sleep/hibernate/wake work correctly. When it's in the thirties or below, the problem occurs every time.

Has anyone else here noticed this? Or are you seeing the problem even when your battery is more than half-charged?

Dell Support just suggested to me that Windows Subsystem for Linux (WSL) could be the cause of this problem. (They say they're certain it's a software issue, so at this point they're pretty much washing their hands of the issue, as the warranty covers only hardware.)

How many of you are running WSL or Hyper-V? I'm running WSL2. (I also run Docker in WSL, using the new WSL2 integration.)

I typically close all WSL terminal windows before putting my machine to sleep, but I don't do an actual WSL shutdown. I may try that to see if it has any impact.

FWIW, Dell Support asked me to try creating a new local user account to see if the problem occurs there too. It does. I'm thinking it might be Factory Reset Time and wondering if anyone here has already tried that.

I have the exact same issue. The problem always starts when the battery level is below 40%. I just need to plug it in for a second and everything goes back to normal. 

Did the factory reset resolve the problem?
