Hello everybody,
My battery is getting drained and after checking the battery log I can see k worker is doing a lot of cpu usage in the background.
This happened after android 4.4.3 update.
Is there a reason for this to happen?
Any suggestions are appreciated.

Hi all
My non-rooted N1 is now suffering from poor battery life (hopefully will get to time it today but basically every morning it's dead) since upgrading to 2.2.1 OTA via O2 (UK).
Has anyone else seen this behaviour, or perhaps have a suggestion to diagnose/resolve? (not just standard battery optimisation stuff please).
Thanks
Mine seems about the same really.

Could be one of the apps you commonly use is having some issues with the new update and destroying your battery life.
You could try uninstalling a bunch of commonly run apps and see if that helps battery life.
Mine seems the same. Maybe your battery is old?
Just to be clear, battery was fine just before the update and now is awful. I've just taken it off charge to see how quickly it dies and i'll keep an eye on what's using the battery (if the about phone > battery stuff is accurate). Thanks
Okay so.. can't seem to do a screen shot (not rooted?) but here's what i've found so far..
From fully charged.. to 10% battery..
While last unplugged for 16h 3m 51s
Cell standby - 26%
Phone idle 24%
Display - 17%
Weather forecast - 7%
BatteryTime - 6%
wpa_supplicant - 6%
Wi-Fi - 6%
Android System - 5%
Android OS - 3%
Gmail - 2%

Does this look unusual to anyone? I'm sure in the past when i've checked this report the display was always the highest. I'm wondering if 2.2.1 update or an app is stopping the phone from sleeping or something?
Any advice welcome
Thanks
My favorite part is that the app Battery Time is responsible for 6% of your battery usage. Irony?
Also, your weather app is setup to sync too often if it's using 7%, IMHO.

You can check if any apps are keeping the phone up, get into the testing app (dial *#*#4636#*#* and go to Battery history.
In there, change other usage to Partial wage usage.
Thanks Rusty. Had a look under partial wake usage and the only thing showing up anything really is 'android system', with about 20% on the bar graph.

It seems like my HTC One is experience faster than normal battery drain when it is asleep since installing Android Revolution HD 7.3. I downloaded the better battery stats app, and would like to know which info I should post so you guys can help me pinpoint what is causing the unnecessary wakelocks.
Hi everyone just got myself a HTC One and I've been experiencing quite bad battery life, usually start the day on full battery around 8am and by 4-5 it's dead or near enough, this seems quite bad for me since my iPhone with a much smaller battery lasted a lot longer, so I downloaded GSam battery monitor and something called kernel (android os) is taking 30% battery usage, is this normal or some kind of bug? I took some screenshots of the battery usage so if anyone could help me out or wants to see the screenshots please let me know, thanks
I've done a factory reset and also running stock version of android updated to latest firmware
Hey guys, getting terrible battery since my note 5 updated last weekend with system (mediaserver), Android system and kernel (android os) being the main offenders according to gsam. Anyone else having this issue? Any ideas for a fix? Check out my battery stats here.
Any input much appreciated!
I remember you from the reddit thread lol. I still have the same drain and after some testing it seems to be the wlan_rx_wake wakelock. The drain is worse on some large networks. After hours of googling the only working solution for me is to turn off the wifi. Have you tried turning off the wifi and checking the drain?

Thanks for the response
My wifi is off whenever I'm not home, but those three processes are still the biggest drains on my battery
Just wondering if you found a solution to this. My Note 5 has the same issue with mediaserver draining my battery
Hi - I have a OP3T loaded with NOS 9.0.
Most folks on NOS 9.0 have said that they are seeing great battery life (about 0.5%/hour drain when idle). I am usually seeing about 2%+/hour drain when idle, and I haven't been able to isolate the problem. The folks over at the OP3T NOS 9 thread recommended BBS and posting here.
I have BBS purchased and installed, and I have attached my dump file. There's a lot of stuff in there!
Can anyone provide tips on how to analyze the dump file to identify the mystery battery drain?
Thanks,
GJ?
Adding a second BBS log file for approx. 8 hours of overnight idle time. I was losing 2..3% / hour over that time.
BBS says that my phone was in Deep Sleep 84.7%. I've seen 5%-10% better on Nougat, but this doesn't seem too bad. I don't think that's enough to be losing 4x as much battery life as I saw just a few weeks ago.
Could my problem just be that my OP3T battery suddenly went bad?
