XPS 15 9510 - Battery Life

I'd suggest generating a battery report in windows to check battery design capacity and full charge capacity. You could do this by expanding How To Generate Windows Power Report in link below and then following steps.

Thanks, but the battery is ok (full capacity remaining).

I think the problem is drivers related, but it's incredibly hard to know where...

By the way, I see your computer hold either a 3-cell "smart" lithium-ion(56WH) or 6-cell "smart" lithium-ion(86WH) battery.

I've posted below already on another thread, but I'd like to help out anyone else in the same boat as me that stumbles across this thread. 

I was ready to give up and return my XPS. I could only do 3.5 hours at most, after disabling as much as I could, running at at the very minimum. 

I saw an advice about Clean Installation of Windows, so I decided to try that as a last resort, and now I run 5 hours with Netflix, 8.5 hours browsing and 14 hours idling. Phew! And my XPS doesn't seem to get very hot anymore too. 

For my case, it must have been Dell's installation system that was at fault, rather than the hardware itself. 

I have: Dell XPS 15 9510, i9, 32GB RAM, OLED (Windows 11).

For those that are wondering, I did Clean Installation of Windows 11 via Cloud.

I am having the same problem with my brand new Dell XPS 9510 with the FHD+ screen. Barely getting 3 to 4 hours web browsing and all the while the laptop was burning up and the fans were running full speed.

So far, as much as Dell Tech Support tried to help, the problem didn't get fixed.

Will try the clean installation of Windows. Hopefully that helps.

I'm the guy that you responded... if I recall correctly, my laptop was also getting really hot too. Good luck with the clean install! Make sure you wipe everything  that's what I did. 

Also I'd like to add my battery life is better than what i originally thought, I've actually managed to get 8hrs Netflix, 14hrs browsing and 18hrs idling. Beyond better that what I expected with an OLED machine 

I just took delivery of the 9510, in my case with an i7 and the OLED screen.  It's a beauty, but like you guys, it ran hot during gentle use and the battery wasn't even lasting 2 hours.  My unit was a Dell Refurb so they had re-installed windows 11 at the factory.  I thought that it might be applications like Steam running in the background, or some driver I had installed.  I thought it could be because applications were downloading updates in the background, but that it would sort itself out soon.  It didn't.

I followed the advice on this thread and re-installed windows from the cloud.  You can do the same in Windows settings by searching "reset".  I removed all data on the device.

After the process finished, I am now getting between 2 and 12 hours, depending on use case.  That's more like it!  Thank you for the advice and I urge other users to try the same thing.  It sounds like Dell need to update their advice to customers, and maybe even figure out why devices are leaving their factory with software installs which are ruining the battery life of their ultra-premium models.

Hi - have landed on this page as am experiencing exactly the same issue with a brand new XPS15 9510....I could sit and look at the battery drop 10% in 20 minutes (with nothing running except a browser, screen set so dim I can barely read it and windows battery app saying nothing was using power). 

I wanted to ask a bit about the process of the clean install....is there any way to do it and maintain all the other installs and changes that have been made in the meantime (e.g. installing Office etc)? I am assuming not, but I spent a lot of time and would rather not lose a Saturday doing the whole thing again from scratch. 

Cheers

No, unfortunately you cannot do that, if you want to run a clean install you have to delete absolutely everything.

You could always try doing it backwards, eliminating all unnecessary apps (everything but Dell update and Dell Power Management -if you use it, but you can always access your power management settings through BIOS- and your own applications), and see how it goes, if it's good enough for you. And if you think it's not, then you can proceed with a fresh Windows install.

Thanks Tatalino  - I was 99.99% sure that was the case, was just wishful thinking there might be some shortcuts, as the thought of spending so much of my precious free time running this kind of task in order to bring a product up to the spec it should have been sold in makes me pretty despondant. 

@ Dell - whilst this may be OK for techy types who will always want to do clean installs etc. anyway, please take this seriously if you want repeat business from people like myself who just want something that works out of the box. 

This is not OK for a premium product like this, not by a long shot. 

Hi, I also had this same problem with my XPS 15 and wanted to clarify something.

If I do the clean install of Windows 11, will all the software dell supplied when I first got my laptop go away? (like the security software or the various dell apps)

And will the laptop run the same as it first did out of the box?

Thanks for your help. I really appreciate it!

I have an XPS 15 9510 with the OLED screen and I was having these problems exactly. Did the clean install of Windows 11 today and wiped everything, and within an hour I had a brand new computer with far better battery life. Trust me when I say it's worth it. I spent too much on this laptop to have a 2 hour battery life, and I'm much happier now with it than I ever was before. 

Do it. Wipe it all.
