CPU process killing battery life after putting laptop to sleep

[TS13]

EDIT: just uploaded a screenshot of the process in activity monitor... now going to reboot 🙁

Every time after I put my laptop to sleep for more than about 5 minutes, then turn it back on, I notice my battery life "estimation" would drop dramatically (going from like 9 hours right before putting it to sleep, to like 3 when I open it)

So I decided to check activity monitor and noticed in the CPU section there was a process labeled kernel_task that was using 100% of my CPU.. so I rebooted (with open current windows after reboot ticked off) and everything was back to normal

anyone have any ideas?

I forgot to take a screen shot, gonna try and take one in a few minutes

I wonder if it has something to do with push notifications and listening for them while its "sleeping".

I'm not sure, but I have app nap off or whatever it's called, so it shouldn't be doing any of that :s

I've also waited for it to go away after a few minutes.. nothing

I have never used the sleep function on any laptop before

Closing the lid counts, you close the lid at least once with any laptop you have while its still on right? 😀

No I only close the lid after it's powered off

I say wait it out, the kernel probably has some maintenance to do. Have you restarted your computer?

like I said in my OP, I restart my laptop every time it happens as it's the only way I've been able to get it to stop.. quite annoying haha defeats the purpose of putting it to sleep

Oops, I missed that, sorry. I still say wait it out the kernel can do some weird things when it's doing maintenance.

Any particular reason for turning it off rather than sleeping it? There's little point in shutting down Apple laptops. I go weeks or even months between restarts.

Seems to be a bug in Mavericks.

Less wear on battery.
