Battery power depleting rapidly

[Jeb E.]

Percentage battery power left depletes rapidly with regular use of the PC, when the computer is on.
This issue does not occur on such a scale in Windows, leaving me to believe this is an issue with something in Linux using too many resources.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Is there a way to easily revert my changes if the latest kernel doesn't
work?

what is the model name of your laptop?
please confirm if this is a duplicate of bug #198665, by confirming the test results for comment #40.

[jebeld17 (jebeld17-linux-kernel-bugs)]

See Sysinfo export.
I'm trying to find the exact model number now...

[jebeld17 (jebeld17-linux-kernel-bugs)]

Model: Inspiron 13 5xxx series, i5368-6453GRY.

Model: Inspiron 13 5xxx series, i5368-6453GRY.
I haven't had a chance to try the latest kernel yet, and no - the issue did not start recently after the latest update.

This issue is not occurring when my computer is off, so it cannot be a duplicate of bug #198665.

[yu.c.chen (yu.c.chen-linux-kernel-bugs)]

Could you please use powertop to track which components are the offenders?
And also please provide the turbostat/top/perf record to check the activity of the system?

[yu.c.chen (yu.c.chen-linux-kernel-bugs)]

ping

[yu.c.chen (yu.c.chen-linux-kernel-bugs)]

Closed due to insufficient data within 3 weeks, please feel free to reopen if you can help provide the powertop result for further debugging.
