My battery drain has got dramatically worse over the last few weeks. My phone will typically lose more than 5% of its charge per hour while sitting idle on my desk. I've tried disabling all sync and location services but it makes no difference. Below are screenshots after an hour of complete idling time during which it drained 6% battery - any ideas for diagnosing this? (I have since re-enabled Gmail sync, as it didn't seem to be having a huge effect on battery drain):
[Android General] jd1639:
Get rid of whatever is syncing your media. Probably Facebook or something
[Android General] itm:
I have no idea what it is (and I uninstalled Facebook a long time ago). How can I find what is causing it??
[Android General] szucsgf:
Try this app:

https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en

It actually lists the apps that are causing wakelocks. I find it more user-friendly than BBS (though less detailed). Might help you figure out which app is draining your battery.
[Android General] itm:
Thanks - I already have it installed, but it just shows the app as "Media" (with the Android logo), which isn't very revealing!
[Android General] jd1639:
Were you trying to download something? It looks like the download manager icon
[Android General] itm:
No - that's the strange thing. I've been deliberately leaving the phone alone, to see if I can work out what it's doing in the background

Thank you
[Android General] 1Android:
Thank you so much for this thread. been spending the entire afternoon reading through. Was hoping to get some help here if I may?

I didn't really understand what wakelocks were until this weekend when i tested out my phone. charged to 100% then took off charger and wanted to see how it would perform over the night while I slept without touching it. was hoping to wake up and see it around 90% or higher but just after 4 hours of sleeping, I woke up and checked my phone to see that it was already down to 82%. I checked the battery stats and it showed my android OS system was eating up my battery like a fat kid with no supervision in a bakery.

Since I'm new to this wakelock, how exaclty do I go about "fixing" them? Here are some screen shots, hoping that someone would be kind enough to help push me in the right direction by giving some tips as to how to track the cause's of my wake locks and how to eliminate them.

I believe the MMC W/L has to do with media. Media Scanner may be the culprit.
[Android General] Khul:
Great post to say the very least.

I've just read the note about gmaps in the #4 and i must say i do differ. There is no need to unintall it.

I get 0 alarms from it. I just used geminis app to remove its autolaunch permissions and then i blocked it using LBE.

So far using LBE doesnt seem to be draining battery life either so seems like a safe choice so far.

greetings!

I have an event5-XXX (the number is different sometimes) kernel wakelock staying on 100% of the time. I ran the ps command and the process with that PID is called "system_service". Anyone have any idea what this could be or how to fix it? I googled around a bunch and couldn't seem to find anything really.
[Android General] Ritesh:
Looks like a problem with your SD card.

This is what I would do. Take a back up of your card first .

1. Run an App called forever gone on your SD card. It will overwrite and clean empty locations on your SD card.

2. Observe, if this helped.

If 1-2 doesn't work:

3. Take out the card, and format it on windows.

4. put card back into your phone and format it again.

5. see if that helped.

If 1-5 doesn't work:

6. Get a new SD card.

Hope that helped.

my nexus for won't deep sleep

Lately i've experienced a significant fall in my nexus 4 battery life, but couldn't find the culprit.

I stumbled in this thread and did some investigation: i found out that the phone rarely goes to deep sleep (less than 5% of screen off time) and what is causing the partial wakelocks are ALARM MANAGER and RILJ.

Sadly, here's where i got stuck: i checked the "raw alarms" menu in BBS but it gave me zero informations, just a list of services, each one followed with a "wakeups: 0". :(

Before going ahead and doing a total wipe i thought i ask here if someone could help me... please XDA, you're my only hope :D
[Android General] Khul:
Try rebooting your phone and leaving the phone alone for some hours without touching it at all. Then recheck data. You will get the culprits...

I've read some people's experiences where they solved gps wakelocks by going outside, opening Maps, and letting GPS get a lock on your location. I can't explain why this works, and I've never had to do it myself, but I thought I'd share in case it helps because I've seen this solution offered several times.

Go launcher ifs a huge resource hog. Get rid of it.
[Android General] kingy9000:
Nova or Apex or Holo

Yup, replace Go Launcher with either Nova Launcher or Apex Launcher, as they are much more optimized for newer versions of Android and thus use newer technologies. Like Go Launcher needs Android 2.0 while Apex Launcher needs Android 4.0.3 and Nova needs Android 4.0.

Newer version of Android required means it's more likely to use newer developer tools when application is developed. Or if you don't have such a recent version of Android you could try out Holo Launcher.

Nova Launcher Play Store Link

Apex Launcher Play Sore Link

Holo Launcher Play Store Link

Hope this helps. :cyclops:
[Android General] brookssw:
I used go launcher for a long time too, because I like its specific feature set. I have it up though, because it does eat its fair share of resources. Luckily,I found holo launcher, which provided most of the same features. After a while I even got the paid version because I liked it so much. Hope this helps.

Hi, my Device is Lenovo K860 running stock ROM ICS 4.0.4 unrooted

BBS shows acm-dormancy, cdc-acm, donw_cpu_wk in kernel wakelock. My phone deep sleep is less than 1% for 7 hours. The cpu runs at 1400Mhz above 90% of the time.

I leave it at 1.00 am at 87% , checked again 08.00 am in the morning and battery at 41%.

I've tried flashing the ROM (also ICS stock ROM then update OTA) still having the same problem. I don't have any other app installed besides BBS and stock apps from the stock ROM. FYI : this phone is 10 days old, it behaves like this since out of the box.

Pls tell me what are acm-dormancy, cdc-acm, donw_cpu_wk in kernel wakelock? And what should I do with them?

Pls help I have serious battery drain. It only last 7 hours on normal usage.
[Android General] stas333:
i get those 2 wakelocks like crazy also. has anyone figured out how to stop them? Freezing the clock prevents alarms from working (not got since my phone is my alarm). Freezing calendar storage prevents me from using any calendars, which i use often.

[Android General] chrcol:
I just keep sync turned off ;) especially as I dont want my contacts synced.

Even with sync off tho I see some apps clearly been naughty.

Some examples.

On my ace I had the flickr app installed. It was planned to use it but I never used it so was installed but never used, however the past few weeks I kept seeing popups stating flicky app has stopped responding yet I never opened it so wtf? Conclusion? app must have been trying to run some kind of sync operation in the background and was crashing due to some kind of bug, I deleted it and gained about 1.5 days battery life. (10 days increased to around 11.5). Another culprit which is already mentioned by the OP is google maps. Google maps seems a good app although large, but its also a drain on battery, it runs in the background doing stuff, if I kill it the chances are if i check my running apps again in a few hours its restarted itself even with GPS etc. turned off. This gained me 2-3 days batter life (7-8 days life increased to 10 days).

note the battery life's I am quoting are with the phone mostly in deep sleep just used for occasional sms and calls.

My S2 is currently over 12 days without charge although its now at 17% left, its got no 3rd party apps installed currently and sync is OFF.

My S3 running a debloated TW rom also has no 3rd party apps installed with sync OFF, it wont reach 12 days this charge as it only had about 65% battery when I finished installing the rom but the battery drain is currently superior to my S2 (losing less or equal per day). 49% left at 4 days 6 hours.

The whole thing is frustrating because some of these apps would be good if they werent so buggy/abusive (ignoring their own settings). Accuweather, push mail, maps, flickr, facebook etc.

I have betterbatterystats and I vouch for it as a useful app.
[Android General] onealvideo:
What's the point if you turn everything off of having a smart phone? :p
[Android General] kingy9000:
Um... No where does it say you need to turn everything off. It's just a helpful guide on getting better battery life by doing things that just suck battery mostly and nothing else. I have a solid 5 day battery life with 15 hour screen time thanks to this guide and other things. :p
[Android General] onealvideo:
I am a business user mostly so turning either sync or maps off is not a viable option.

I am looking more into the tasker way of doing things. When I launch maps it will turn everything on, etc...

Either off or on just won't work in my situation.

Happy to see 5 days of battery though! :thumbup:

He could be getting that if it's just light usage and an extended battery, for example I'm *usually* a heavy user keeping cpu at highest clock speed when screen is on and I get 8-9 hours screen time with my S3 and zerolemon battery, if he just has the screen on surfing the Web with wifi and a lite browser or just texting I could see 15 hour screen time happening

Ask and Ye Shall Receive

Here are the screenshots I took a week ago. Keep in mind that I have even better battery life now as when I was doing that run I left my phone on by accident in recovery mode for a little long. Also it's only at THIRTEEN PRECENT in the screenshots. If anyone wants my setup I would be glad to hand it out. And also yes I do use my phone to the ultimate but with caution. :D

5 Days with 13 hours Screen On Time at 13% Battery (I could have easily made it to 15 hours even but I have only just started another cycle after charging. :)

[Android General] kingy9000:
Well my setup is Sprint Samsung Galaxy S3.

I use:Liquid Smooth ROM by Team Liquid

This ROM in my opinion is the best ROM with the perfect balance of stability and features. (I have never had it crash on me once)

Next I flash:

KT747 Kernel By Ktoonsez

This Kernel is amazing. It's updated regularly and it has a fantastic tweaker tool built in.

Next:

I flash SuperSu by Chainfire

Amazing Root Permissions Manager App

Next:

I flash Google Apps (This is only needed for AOSP Based ROMs)

Next:

I flash TK MOD 1.0.4 by Team Kernelizers

This is a great MOD to go with the Kernel mentioned above and has awesome build.prop tweaks among other things.

Next:

I flash Crossbreeder Mod by idcrisis

This MOD has sped up my phone slightly, has an adblocker built in, and is regularly kept up to date.

Next:

I install Rogue Series RED Theme

This allows for slight better battery life because the Galaxy S3 has Super Amoled Screen meaning Black and Red are very battery friendly.

And of course I followed this guide to eliminate battery wakelocks now having no unnecessary wakelocks at all.

Now, could someone please explain to me what this means in English?

Many thanks in advance!
[Android General] kapil_dheer:
It means in the recorded span, the app kept the phone awake for 261 seconds and ran for 425 different instances. Also this amounts to a total of 2.6 percent of the total time awake for the phone.
[Android General] nollan:
Many thanks, mate!

How should one interpret the count-figure? Is 425 a high number or does the answer to that depend on other factors?
[Android General] kapil_dheer:
The best way to judge this is run the monitoring using the custom ref. Mark when you don't intend to run the phone for a long time.

Normally while you intend to sleep. This gives an uninterrupted monitoring of about 8 hours.

This let's the app to monitor the phone while it is not intended to do anything.

Any partial wakelocks you find are the battery hogs.

The custom ref. Clears all the earlier logs and starts fresh monitoring from that very instant.

Save the logs in the morning and try to read them.

You can upload them on bbs thread or here if you require any help. But first give it a shot yourselves.
