Same issue with power here on my 9570! In fact I just checked after one month of plugged-in non-use, turning it on resulted in dead battery in < 3 minutes. What's crazy is that if I let it charge now, I will get 3 solid hours of battery life. The battery health indicates 2/4, it's definitely not a fully spent battery.

The other thing that has driven me crazy is the wide-gamut 4K screen. The text is nice and crisp, but good luck with sRGB content. Basically all content for non Adobe professionals is fubar'd. I eventually made the situation tolerable by finding an old version of Dell PremierColor and using its sRGB profile (newer versions of the software on Microsoft Store quit working on the 9570 and the color profiles do nothing - imagine that). Still get terrible color banding and crushed blacks, and I'm not even sure investing in a colorimeter would fix it.

Overall I've come to the same conclusion as you. In 2018 this was a $2000 machine (Costco price below retail), and I also can't justify giving Dell another chance.

I had a 9520 for about 5 years. I had two issues, which was a broken left hinge (4k touch screen was two heavy for that part, I believe in the XPS 15 actually didn't suffer from the same issue), and swelling batteries, which caused various knock on issues. I also experienced the same issue with batteries from the dell latitude I got from work. Seemed to be a dell thing for laptops left plugged in constantly. I never had to deal with overheating issues despite having a Xeon (although it did get quite hot).

Its a shame because otherwise I really liked the laptop. Gorgeous screen, good trackpad and keyboard, and a perfect size imo.

That's so funny, because I'm in the same boat with my XPS 9570. I bought it for personal use because I had an amazing experience with a 9370 developer edition at my last job. I figured it would be the same, but that was extremely naive. I got the i5-8300H SKU with an empty 2.5" SSD bay, 53Wh battery, and a 1TB drive for $800 and change with the intention of plugging it into my GTX 1070 eGPU at home. I figured that this would be like, a power-sipping config.

NOPE! It wakes itself from lid-shut sleep and cooks itself whenever I put it in a bag, it will crash and reboot if the Thunderbolt cable gets jostled, and I get maybe 90 minutes on battery life after weeks of optimization script fiddling. I wanted to like it so badly because at the time, the processor was a steal. Matching the old 7820-HQ's performance with a bottom-tier i5 8300H felt like magic, but nothing else lived up to the hype.

> around power management, wake behaviour, and thermals.

Can't speak for wake behaviour cause I have never encountered issues on my 15" 9570 but you can actually make it much, much better with a bit of work.

You need to work around plundervolt flags and enable undervolting(there's a tutorial in some reddit threat on how to do this), then undervolt CPU a bit, this way it almost never throttles. As for thermals, just changing paste to Kryonaut and adding few stacked thermal pads so they connect to the chassis in few places according to some tutorials I found made insane improvements. I play Valorant on mine and I went from almost constant throttling, to no issues at all, even during longer sessions. It's also almost never running fans on higher speeds during normal work.

But I agree, my next machine will be a MBP with Mx chip, I don't want to put in so much work into something that costs a small fortune just so it works properly.

I've had the same experience with my XPS 9560. Past few years I've had "TPM device is not detected"[1] issues. Tried all the different solutions and nothings fixed it. Dell have never addressed it with a BIOS update.

I don't want to go back to OS X, but its hard to find good build quality and a high res screen.

Also, my battery was terrible after a couple of years. I had it plugged in as well. I bought a replacement this year and it was easy enough to switch out. Hopefully I can just keep this going and use it as an RDP machine.

I think the real garbage part of buying an XPS from Dell for professional developer work on Linux is that they will not provide any support for the device. Particularly when you report driver, sleep, or other software level issues that they ostensibly provide with OEM installed Linux.

Yeah my 15” xps was pretty bad too. Coworker and I both had this issue where one key press would result in the same letter being typed twice. Coworker sent his machine back several times but never got that fixed. I just used an external keyboard most of the time. Besides that, my machine’s battery ultimately puffed up and made the trackpad impossible to click.

> supposedly sleeping in lid-shut mode but be cooking itself for no reason

Same. It fires up full fans and all in the middle of the night.

It’s a nice form factor, but much like me growing tired of stuff like “android slowdown syndrome” and me getting an iPhone last fall … I feel like I’m being pushed to try a Mac laptop for a cycle….

I just don’t want to deal with this stuff anymore.

> with it having been plugged in in my home office for basically two straight years during the pandemic

Yeah, my second seems to have succumbed to that as well. There's a setting in the BIOS that says "I plan on keeping this plugged in all the time" and it'll do better battery management that way.

I’m thinking, that since your battery has passed its cycle limit, maybe the increased internal resistance of what odd causing all the heat issues. Maybe, change the battery?
