I've been using this laptop for several years and I've found it has serious problems:

- After two years of use the keyboard lifted. I discovered that the battery had swollen and had to replace it.
- Devices connected to the USB-C port are not detected unless you restart the computer with the device plugged in. And they give problems anyway, reboot, etc. And this is not solved with BIOS, firmware or driver upgrades, it is a proven motherboard problem.
- If you connect an external display it is not managed by the nVidia card but by Intel, which is much worse.
- The black plastic is peeling and oozing, it is of very poor quality.
- The charger cable burned out.

I have owned this laptop for almost 3 years. It was incredibly expensive and supposed to be top of the range to run powerful design software. It has been completely frustrating throughout:
1. The fans are constantly on so it's really noisy, giving me a headache
2. The 4k screen is not compatible with multiple types of software - you can configure it to work with one piece of software but then it doesn't work with a different piece of software. Really frustrating.
3. Nothing alerted me to it not being compatible with external monitors that are not 4k. It can operate them but if you move software from one screen to another you have to change the settings on the software to make it display properly on the other screen - incredibly frustrating
4. It's constantly switching unpredictably between monitor or laptop speakers; external or internal mic; external or internal webcamera
5. It's supposed to be powerful but it can't run Microsoft Teams - all other voip software runs fine but it just can't cope with MS Teams
6. You can't daisy chain monitors, so can only have one external monitor connected
7. It gets really hot - even though I've put blocks under it to get lots of air under the fans
Overall I'm really not very impressed, although Dell support have done their best to support me, although they've said the issues are the problem of the software providers or of Microsoft and Microsoft and the software developers have said it's Dell / the laptop's problem.

My battery low, I need battery pin dell xps 15-9560 regularly hit 8 hours on the 9560. same picture (https://linhkienlaptop.net/images/thumbs/2020/09/pin-laptop-dell-xps-15-9560-chinh-hang-products-796.jpg)

When will you review the Lenovo Ideapad 720s 14" and 15"? Since they've been out for months I've been considering these as XPS/Spectre/Zenbook alternatives but I can barely find any comments on them online.

Waiting for this too!!

It is a great review on this unit, and cant wait to see new Dell xps 15 review from you :) have you tested 3Dmark 11 on this xps 15 9560? wondering if this will be lower than Asus zenbook flip...

@kninez:

Yes I assumed the question was asking much. Actually number of pixels on the screen are the same so running at lower resolution will not affect battery life at all. On the other hand, turning off the touchscreen may boost an extra 30 minutes or so. But the far most effective method is to undervolt the cpu and gpu, repaste and tweak OS' native power settings. A more aggressive approach would be to use a SATA 3 SSD instead of a HDD or PCIe, LPDDR3 memory instead of DDR4 and disabling unused ports through the device manager.

if you run the 4K model at 1080p, how does that affect performance and battery life?

You'll get better graphics performance but identical battery runtimes.

I don't think he/she was referring to the gaming runtimes, they were asking about lowering the resolution from 4k to 1080p for regular use (browsing the web, productivity, videos/movies, general media consumption etc).

How much extra battery would they get if they lowered the resolution.

To answer that question, I think it will not be as good as the native 1080p screen. But it will be better than native 4k battery runtimes.

Got mine today (7700HQ, FHD, 16/512GB).

- Coil Whining
- Fan rattles
- Shell warped - wobbles on the table while using

At least no dead Pixel and Display Bleeding.

Still send it back. It's not acceptable for this price. 9 months after introduction still the same flaws... Seems like Dell doesn't want to improve.

Additional got a SK Hynix SSD. Not near the quality of a Samsung SM/PM961 they used for the reviews. Looks like they randomly use any SSD they can get - in a 2000 EUR device.

Ordered it due to a 20% discount but it's the last Dell I buy. Already had bad experiences with XPS15 L502x in 2011. It could be a perfect Notebook: Design, display battery, ports etc. if they use a Intel Wifi 8265ac, 1050Ti Mobile or 1060 MaxQ, Samsung 961/981 or Toshiba XG5P and especially improve their quality.

Will go for a Gigabyte Aero15x.

Shouldn't the display score (84%) be higher than it's FHD version (87%)?

Ok can someone or Notebookcheck please answer me if the UHD panel has PWM flickering on all brightness levels??? I don't understand why it is not included in the review... It is the deciding factor for me if I'll buy this laptop or not.

Can someone please answer me id this UHD panek has pwm on all brightness settings? Does it even exhibit PWM @100% brightness??

An average should be 87% and the drop of throttling 8,8%, not 10 (670/735 not 735/670!).

Great review with tons of useful information!

"We will see in a future review whether or not the cut-down Thunderbolt 3 port can hinder future external graphics support on the system."

The other review of the 9560 says, "We are currently preparing a review of the Asus XG Station 2, and we will also try to test the XPS 15 with it."

Is this review published yet?  I can't seem to find it.  Any information on using the XPS 15 with an eGPU would be great, thanks!

When checking for PWM, the oscilloscope definitely shows oscillations . So how come in your review you say it doesn't use PWM?
