Cool. What are the approximate power usage numbers you see in watts?
** Summary changed:
- High Power Consumption
+ Higher power consumption when running gnome-shell compared to unity

I installed a new kernel 4.20 on Gnome-shell and the power consumption was
almost same/high.
Then, I removed the kernel and switched back to 4.18 that comes with 18.10 base
and installed unity-session and I noticed a sudden decrease in power
consumption. I don't know, if the problem is
Some notable CPU users from that file:
16:57 0:42 /usr/lib/snapd/snapd
16:57 3:01 /usr/sbin/preload -s /var/lib/preload/preload.state
16:57 0:30 [irq/125-iwlwifi] <--- this is the Intel Wifi driver
16:57 0:21 /usr/bin/tor --defaults-torrc
/usr/share/tor/tor-service-defaults-torrc -f
Ok. here's another file. Left the laptop idle for few hours, still high
power usage.

Did you confirm the power usage is still too high before sending
allprocs.txt?
Even that second file doesn't seem to show any long term execution. So
maybe forget about leaving the machine idle. Just leave it on for
multiple hours/days, use it, and then please send another allprocs.txt.

Please ignore the previous output file, took that too soon after system
boot.
Consider the attachment with this comment, the power usage is still same
and high. I left the machine completely idle for longer.
** Attachment added: "allprocs.txt"
Thanks. That only shows a few seconds of CPU usage. How long was the
machine running when you collected that?
Can you please try again, leaving the machine idle for as many hours as
possible?
Also, did you confirm the power usage is still too high before sending
allprocs.txt?

OK. There's one more thing to check before we can blame the kernel...
Reboot, login, and leave the machine completely idle without ever having
launched any apps. Is the power usage still too high? If yes, please
then run 'ps auxw > allprocs.txt' and attach 'allprocs.txt' here. Then
try
Disabled snapd service and left the laptop idle, almost same power
usage.

Thanks. Although gnome-shell, snapd and deja-dup-monitor are the top
users for the previous 60 seconds, it also shows that snapd has used an
accumulated 4m40s which is way above everything else.
Given your uptime is 5h34m then that means snapd has used an average of
over 1% of your CPU for that
Please ignore the previous one, I took that screenshot sooner. Consider
this one.

OK. Next we need to figure out what system component is to blame.
Please open a Terminal window and run:
top -d60
That will only update once per minute. Please wait a couple of minutes
(of doing nothing) and then tell us what processes come to the top of
the list, and what their %CPU is. Or
Thanks and I tested it many times. Kept the system idle with zero apps
running and the power usage was still high.

try with all apps closed (just log out and log in again). Is the power

1. Closed firefox and left the laptop idle for an hour and the battery is
almost fast drained again.
2. removeaccesibity extension is important for me because I have a HiDpi
display and normally the screen looks tiny and enabling Universal access helps
and at the same time I don't like the icon
Please also try shrinking the Firefox window so that it is not touching
the screen edges (not touching the Gnome panel and Ubuntu dock). Does
that improve things?

Thanks, that's a nice report.
It appears your main power consumers are Firefox, Gnome Shell and the
Intel graphics driver. Actually that's all likely just due to Firefox,
which may be consuming more power since it is now being composited
through Gnome Shell and both of them use the Intel graphics
Hey thanks,
I have attached the powertop report. Can you confirm.

Thanks. Please try installing 'powertop' and then run 'sudo powertop'.
You may find a reason for the high power consumption there.
Also, please try running regular 'top' and see if any process is using
high CPU.
