So I've been having some issues lately with my battery life and I think I've found the cause. Its a wakelock called "Copsdaemon" in my battery stats. It uses over 60% of my battery as it keeps the CPU on for long periods of time. It also stops my phone from entering deep sleep. Has anyone else experienced this issue? Is there any fixes for it? What is this process and mainly how do I stop it? Cause it is super frustrating to have a battery life of about 10 hours with not much use at all. Thanks for any replies!

Hi, its to do with the 2G network. If your in a good network area set it to 3G then deepsleep will work. If you havnt got a good 3G signal then I don't know apart from a rom change

Hi experts here,
I am new i9000 user coming from G2.
I flashed XXJPK for days, found that my battery drops very fast.
I stop all data access at night and the battery still drops...
I found that the 'Display' uses > 80% !! (even when I slept for 8 hours)
Attached is the screen cap of my battery stats..
Do anyone has the same issue?
This is Android Development, not Questions & Answers! Please post in the right sections!
What have you installed after JPK? Task killer? Lag fix?
Mine is not doing that. I did a hard-reset yesterday, installed my apps (no task killer, no root, no lag fix) and disabled everything (WiFi, bluetooth, GPS, 3G, autosync). Battery did not drop even 1% in 6 hours.
Display should not take any battery if it's off. Maybe you have something that awakes the phone constantly. Check autorefresh on weather, e-mail, twitter, news feeds... I usally have that disabled or set to 8 hours minimum.
got the same problem here.. i do got the docrom (custom rom) ,auto killer installed and lagfix (OCLF v2+) it goes from 100% to about 60% in 9 houres.. without doing a thing.. on top of that i got juicedefender ultimate installed.. but it doesnt seem to help at all..
The problem is why the 'Display' uses > 80% while I off the screen for hours?
Got the same problem here. I just reverted back to jm8 (eclair 2.1) with takayuma Rom.. I think all froyo versions have battery draining issue
I think, you guys must make this and maybe fix battery issue:
Refreshing battery stats after Odin or flashing (important)
or me personal, for my Galaxy very helpfull was this HTC Desire methode:

I'm having exactly same problem with you. My brightness is 75% even in sleep mode and it drains the battery. I guess thats the main culprit to solve my battery draining issue. I wonder why it happens to certain people, because some users only have 48% for brightness and their battery can last more than a day
** apparently using Eclair 2.1 doesn't solve the issue as my brightness is still 70% ... I've tried the batterystats.bin fix and same thing happens. Damn !

It's true. JM8 and the battery fix doesn't help.
But I found that when I turn my connection from 3G mode to Wifi mode, my battery drops only 10% overnight.
I think there is some problem in the 3G connection.
Do you think this is kernel related?
One way to keep the drain down is getting a black theme such as the Transparent theme and setting a black background. Because of the AMOLED screen black is basically 'pixel off'. It helps just a bit.
I have similar experiences with WiFi vs. 3G, 3G drains battery awfully fast whereas WiFi seems to be consuming significantly less power.
Has anyone had any issue with the battery draining out rapidly overnight when the phone is in idle without any apps running. My battery remains around 75% before I go to sleep but the next day morning it drops to below 30%........am confused :S

Maybe you were really running apps, or some of them started updating.
You really need to check up on your phone activity.

It's not possible without any logical reason, and this one can only be an app running in idle wich can't even go CPU to sleep.
It's pretty simple to search for the issue, just need an app such as "CPU Spy" who can help you to find WHAT is draining your battery.
Before do it, I advice you to test it without charger (evident ) let us know

Your phone is not getting into deep sleep. There might be some apps giving wakelocks or kernel wakelocks. Install better battery stats and cpu spy from market and identify the culprit!
Hit thanks if it helped :-D

Sleep less -- more battery
probably it is because of the samsung push service. froze it with titanium back up or uninstall it.
Hi!
Can someone please tell me as to why my battery drain when the phone is idle is so high?I have checked BBS and wakelock detector and it looks like there is no problem in my phone in going to deep sleep. .for the entire 10hr duration overnight it was on deepsleep so there is no problem with any particular app keeping it awake. .but even during 10hr of deepsleep it lost 20% of battery?If someone can think of why this is happening or how to rectify this it would be much appreciated!Also the same thing seems to happen on any rom/kernel so no issues with a particular rom/kernel. .Thanks guys!
I'm getting a regular wakelock labeled msm_hsic_host. I thought this was related to the phone's radio, but I turned on airplane mode and the wakelock continues. Anyone know why?

You probably have a rogue app polling for a radio signal and putting it in airplane mode is making it worse.
The same wakelock doubled my battery drain last night. I had it in airplane mode overnight. Going to leave the signal on tonight and see what happens. I was getting between 3-7% but it was 15% last night.
Tested it again last night. Unplugged at 4pm yesterday and used 5% battery overnight. I just hit 24 hours with light/medium use today and battery is at 75%. I know others have shared this but battery life has certainly improved with time. The wakelock is certainly reduced leaving data connected overnight. Hope this helps.

How are you able to see wakelocks without root?

GSam battery monitor has an option at the bottom that looks like a vacuum. Its called app sucker. Once that screen opens there is a drop down menu at the top that allows you to see the kernel wakelocks. Then you can select each wakelock and the next screen has a button there to google it. Hope this helps.

It does! I'm used to better battery stats, and still learning gsam. Thanks!
Looks like it's a big problem for alot more phones. I have the same wake lock also. I get about 1% per hour by leaving it overnight. Is that normal?

I think it is. But alot depends on your settings and the strength of the cell connection. Actually the cell connection is about the biggest battery drain that I have. I use Tasker on my phone. It disconnects my cell connection when the screen times out and limits anything running in the background. Calls and texts still come through. When the screen wakes up everything reconnects. Some would say the settings I use are extreme but I get good battery life from it. Tasker can be difficult to start at first but there are some good youtube how-to videos. Im hoping the new battery saving feature in lollipop will make it unnecessary to regulate any settings. I guess we will see.

This. I use tasker to turn off data and auto sync when I go to sleep (because its literally a waste of battery) and I got 0% to 2% drainage overnight (total, not hourly) but that was with a custom rom. I expect 0.5% to less than 1% per hour with this phone because at idle with 4g on I drain about 1%/hr
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
