Huge battery drain on brand new XPS 9550

I am seeing a huge battery drain on my XPS 9550 within months of purchasing it.  I am using Windows 10 and on the latest patch that came out in Jan 2017.  The battery power goes from 100 to 0 within 1.5 hours of using.  When I look in the 'Battery Usage by App', I see Chrome sucking up 51% of the battery, Acrobat PDF using 23%, Word using 9%, etc. Is anyone else experiencing this? It's a shame if the delivered battery is the cause  of it all.

RE: Huge battery drain on brand new XPS 9550

Hi jnadaraj,

Thanks for posting.

Here is some information you may find helpful:

Q
How long am I able to use my Dell laptop on a fully charged battery?
A
Many factors affect the amount of time that a portable computer battery can deliver power before it must be recharged. These factors include the configuration (processor, memory, etc.), types of applications being run and display brightness.

Dell uses industry standard benchmarks for battery run time claims. For more information on battery run times and benchmarks, the white paper, "Understanding Battery Life in Portable Computers" is available at: http://dell.to/2luVTMl

RE: Huge battery drain on brand new XPS 9550

Thanks for your response. But none of the info helped. I have it on lower brightness, delivered Config, and nothing out of the ordinary.  The only other thing I can think of is it sort of started to happen only after the latest windows patch in Jan 2017.  Until then, my battery performed okay.  Are you aware of anything in the new Windows 10 64 bit patch that could be causing this?

1. Do you leave it off AC power overnight or for any extended period?

2. Do you shut it down regularly or just put it into a suspended status?

You might try running the command below to see if it sheds any light on the situation.  Keep track of where the resulting file is stored and copy it to the desktop to open.  It will take a minute to run, so give it time and close all other programs you have open.

powercfg -energy

RE: Huge battery drain on brand new XPS 9550

hi, this is still a major issue. Can one of the Dell analyst comment on the log file please?

RE: Huge battery drain on brand new XPS 9550

 "The battery power goes from 100 to 0 within 1.5 hours of using "

That's a very short time for a battery. Please check the battery's health in the BIOS:

1. Power off system.

2. Power on system, quickly start tapping the F2 key continuously. You should be in the BIOS. The battery health should say "Excellent ".

RE: Huge battery drain on brand new XPS 9550

Or.....

right click battery icon at the bottom of taskbar, and then click Dell Command | Power Manager. I'd suggest you change battery settings and see if that will make a difference, see image below:
