Mycket läsvärd review.

Tydligen en del bekymmer med 9570 :/ Så som batteriet, annonseras och säljs som 97W men egentligen endast 87W och sleepmode drar en massa batteri utan användning under natten.
Issues
Constant crashing out-of-the-box. Changed to AHCI (from RAID) and swapped the SSD, and this seems to have fixed this.
Crashing when GPU is stressed after 2-3 minutes (BIOS update 1.1.4, currently pulled from Dell’s drivers website for some reason, seems to have fixed this). Possible the GPU was not downclocking despite high temperatures, leading to instability.
Two batteries so far have 9.9% wear brand new. Dell has advised me that “the batteries are operating as designed”.

"With the 9560, Dell increased the capacity of the 6-cell battery from 84Wh to 97Wh*. Since 99Wh is the legal maximum for air travel, the battery remains the same size. The efficiency of the Kaby Lake refresh plus 15% more battery capacity meant that the 9560 got around 2 hours more battery life than the 9550. However, Coffee Lake is significantly more power hungry under multi-threaded load and slightly less efficient at idle, so I expect a slight decrease in battery life with this generation rather than an increase. While the CPU consumes less than 1W at idle, at full CPU load, the i7-8750H pulls an extreme amount of power — over 75W on AC! This means that it will be very important to tame background tasks while on battery power, as keeping the CPU awake with indexing or other tasks will significantly dent battery life. Also remember that the UHD touch display will use significantly more power at any load, so if you are trying to figure out if the display is worth the hit on the battery, you can assume 20-30% less longevity with the UHD/i7 SKU.
*Despite attempting to calibrate twice, my battery is showing 9.9% wear out of the box, meaning its true capacity is 87Wh. I also requested a replacement battery, and that one had 9.9% wear as well. I have seen many reports online of people with roughly 10% wear out of the box, and my conversations with Dell support have ended up with “the battery is operating as designed”. I hope there is nothing fishy like the “97” Wh battery being 87Wh standard, and I imagine if that were the case then everyone would have noted by now. Still, I have to note that this is an ongoing issue with the battery.
Idle (30% brightness, power-saver): ~6-8W (12 hrs)
Light load (browser-based work, listening to music): ~10-11W (9 hrs)
Heavy load (analyzing music with Rekordbox): ~40-45W (2 hrs)
Gaming: ~45-55W (1:30-1:45 hrs)
Battery life is overall decent for a powerful laptop of its size, but it is unfortunately not an improvement over the 9560. One of the weaknesses of the hexa-core Coffee Lake-H chips is the much greater potential maximum power draw from the CPU. This tends to reduce battery life significantly if you are not careful about what kinds of applications you have running.

Såklart man känner sig en aning osäker.
Något som känns jääääätte dumt är alla onödiga tillägg Dell automatiskt propsar på, som McCafe security i 12 månader, 30 dagars MS Office och "1 års Premium Support på plats" vad det nu egentligen betyder... Tror Dell hade kunnat dra ned priset en aning om man slutade tramsa med allt lull lull vid sidan om
