[Q] something is draining my battery - how can i tell what it is?

So i rooted my evo and installed a custom rom pretty much as soon as I had it out of the box. And then started installing apps. And i've pretty much NEVER had a fully charged battery last for a whole day even with very little to no usage of the phone.
A few days ago my friend also got an evo but hasn't rooted it or installed any apps yet. And he is easily getting TWO days or more out of a charge.
so i decided to do a full wipe of my phone, and what do you know, I'm suddenly getting 2 days out of the battery, maybe even a little more then 2 days.
Previously, i had setcpu installed as well as system panel. And i was never able to figure out what was draining the battery. When i looked in system panel the only thing that was using the cpu a little bit was system. Pretty much every other app listed was showing 0.1% of cpu usage.
So i'd like to know if there's a better method to figure out what's draining the battery. Do I have to install apps one at a time and wait a few hours/a day to see if the battery starts going down? or is there a better method?
thanks

I always check the awake time versus the time on. If the wake time is very high that means there is an app acting up.
What I'll do to investigate which app is I'll just go to the little stock battery report thing and look at what is using my battery.
Also, it should be noted that be wary of the facebook app. That thing is a complete and total battery hog. It was draining my battery from 20% over the course of an hour.

I was checking the stock battery report - it wasn't showing me anything useful when the battery was going dead.
right now i'm getting amazing battery life compared to before.
90 minutes since the phone was unplugged and it's only down to 96% and that's with me using it a bit. Previously, it would have been down to 85-80% by now.
I just have no clue at all what was causing the drain. I was hoping there was a better method other then installing apps one at a time until the battery starts draining to figure out the culprit.

There's an app called Watchdog and it monitors the background activity happening on your phone. If some seems to be getting out of hand it will notify you.
I had the same problem I installed Smobile security and it was KILLING my battery. Watchdog was able to tell what it was.
Hope this helps.

It looks like watchdog does basically the same thing that system panel does. and system panel wasn't showing me anything unusual. System panel shows the cpu usage of apps - and none of my apps were showing high cpu usage.
I guess there's really no app that can actually show you the battery usage per app - it can only show you the cpu usage.

You can try SpareParts from the Market,it may help you see if you have a wakelock issue of some kind and its free so no harm if it doesn't help.

actually, the rom i am using already has spareparts in it. I'm not sure what you mean by wakelock though. How do i determine that? What is it?

Battery life

Just a general question, i have no problem with my devices battery life during useage, but whats annoying me is how much battery life i'm losing when the device is "asleep"!
i can lose between 10 and 25% battery when the device is asleep overnight, or while i'm at work.
this isnt a one off, it seems to happen most of the time, so i'm having to charge it every couple of days, rather then once or twice a week.
is this a general problem, or do i need to do a reset.
thanks

There are many apps found out there (some need root) that can track down what's eating the battery and or preventing device sleep. Google Search app is probably one of the culprits. I disabled it long ago.
If you're not rooted, try to disable some "bloatware" apps in your device settings > applications. .... If your rooted, freeze apps from self-starting using greenify app or remove with Titanium backup app. Just backup them first
I could go on and on, but at least some pointers where to start. Good luck

Have your wifi sleep when not in use. You may have some apps hijacking your bandwidth. You should only lose a few percent overnight...

I have the 8.4, fully stock and hardly a thing installed on it (it's like my 5th tablet for use) and I think its at 50% after idling for 15 days.
only thing that beats it so far is my Nook HD+, which probably idles for 4 months, literally.

having the same problem.
i do have google search in my pages. disabled it , gonna see how it goes ...
whats a good app to recommend that i can check out what is causing my device to wake while it should be asleep?
im rooted btw

Help with identifying wakelocks/battery drain

Hi everyone, for the past couple of weeks I have had more idle drain than usual on my rooted Nexus 5x. The problem has persisted across multiple roms. I recently returned to stock, and waited a day to restore my user apps with Titanium Backup, and in that day, the stock rom did NOT have the problem. Then, when I restored user apps, the problem returned. So it appears that one of MY apps, not the OS, is causing the wakeups. However, in both BetterBatteryStats and Wakelock Detector I cannot find any particular wakelock(s) that seem to be causing this issue.
The only concrete evidence I have is the Android built in battery details screen. In the screenshot of the graph and the awake/screen on bars, you can see constant wakeups starting around 2pm (when I restored user apps). Before that, the phone mostly slept while the screen was off, but after 2pm, it has been waking up constantly. I have also attached Wakelock Detector screenshots (Have not used BBS yet on this ROM). They show awake time that is much higher than the sum of the listed wakelocks. (Note: the 52 minute "Photos" app wakelock was a one time thing today, the problem has persisted without that.) If anyone can figure out what might my issue is, I would hugely appreciate it! Thanks!

Best way might be to restore one app per day to figure out which app it is

I was hoping to avoid that, in case anyone had any ideas. But I have a feeling I'll have to. Thanks!

I believe I suffered the same issue, and I have a solution. Not a fix but solution...

Seeing the same issue ... have disabled the AutoSignInandSync service, waiting for the results and will update if that helped.

Sigh... Battery drain and probably wakelock issues

Hi,
I have an unrooted Note 4 that is updated to the latest marshmallow. Lately I have been having battery drain issues. I have GSam Battery Monitor to see if I could figure out what was going on. The only thing that it is telling me is that my phone is pretty much staying awake all the time. Unfortunately I cannot tell much more than that.
My question - is there any way at all for me to figure out the culprit? I looked online for a while and saw references to using Wakelock Detector on unrooted phones with a couple of ADB commands, but that doesn't seem to be an option with Marshmallow.
So, short of rooting, is there any way for me to figure out my battery issues and what's keeping it awake?

Ha! I'll answer my own question. It turns out that you can do this with GSam Battery monitor and a few ADB commands. I updated the app to the latest and went through the settings and it had a little tutorial built in. It took me just a couple of minutes and now I can view wakelocks, both app and kernel, in the app.
If only I could do this with wakelock detector. Still, I'm happy with GSam Battery Monitor.
I'm assuming that I'll have to redo this after every reboot, but that's cool

did you calibrate your battery since your last update? is that when issue began ?im not on stock, but ive had major battery issues in the past. the issue was caused from flash . the solution ended up being charging phone to full then calibrating battery via an app i used root essentials but not applicable in your case

Battery Drain

Ever since I updated to 8.1.0 with December security patch, I've noticed my battery draining faster than normal. I was getting 4-5 hours of SOT with around 45-50% battery left. This was after being off the charger for 12-16 hours. Now I'm getting about half the SOT at similar numbers. Anyone have any ideas?

Excuse my stating the obvious, but you need to find what process or app is using the battery. You should be able to get a rough idea just using the new features under Settings>>Battery. It will identify which apps are using the most juice. Run the phone in Safe Mode to see if your battery life goes back to normal. It could also be a service like Google Play Service which sometimes wigs out and starts chewing battery. Are you rooted? If you need more detailed information there are battery drain apps available to help isolate the problem (BBS and GSam). These apps require root to give the best results.

Not rooted and currently locked. I've downloaded GSAM and have adb permissions and it simply says things like Chrome, RCS Phone and Play services. If you see from the photos below you can see what I'm talking about. Chrome currently isn't that bad, but yesterday and the past couple days it's been like 9% or more of the battery.

Two things: I've never seen phone or kernel use that much battery. On one page phone usage is 33 seconds, yet it used 9% ? I think RCS is running the background all the time. See if you can toggle it to not run in the background under Settings>>Apps>. High kernel I'm guessing is a kernel wakelock or multiple. You've probably loaded app(s) that are creating the problem, but you need to find out which one is causing the wakelocks. There is a wakelock detector "lite" app that doesn't need root but I don't know how well it works. I know the root version works well. Lastly, on the first screenshot with the battery, scroll to the bottom of the page and see which apps are listed there. I'd be willing to bet if you ran the phone in Safe Mode, your battery drain would disappear, meaning your user apps are causing it.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.
Edit: I'm wrong about that it was the play services.. I'll have to start uninstalling the apps to determine which one is draining the battery I guess.

RCS can be a real battery hog, but I don't know why. I don't have RCS on AT&T. Do you use Messages as your primary SMS? Open Settings>>Advanced and see if you can toggle off "Enhanced Features". Open properties and check if it is using battery optimization. If it is not, set Messages to battery optimization. You can always turn these back on later if the battery drain remains.

My battery life has been restored to pretty much the same as it was with 8.0. I also noticed poor battery life after installing the 8.1 update, even though they changed the way battery life is estimated with this update (supposedly). Something just felt off, but now everything feels great! I am fairly certain what changed is installing the Greenify Magisk module and/or the Google play services doze module (this enables battery optimization on the Google play services app). Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

In my experience that's really good.
Before 8.1 I noticed about 11% per hour during screen on use and about 0.33% per hour while on stand by in my pocket or a little bit better if it's just sitting on my night stand not moving while I'm sleeping (I think doze is more extreme in that situation) which seems to match what you are getting. Based on that screen shot I think that's like 8 hours screen on time over like 35 hours for a full charge. I've done a little bit better but not much. That's excellent battery life.
Since 8.1 it has dropped. Best now is maybe 7 to MAYBE 7.5 hours over maybe 26-28 hours. In my experience battery life always drops after an update but this case is far from the worst. I remember when my Nexus 5 updated from KitKat to Lollipop. The battery drop was awful and to make matters worse the battery life of the Nexus 5 was pretty bad to begin with.

So in my last reply I thought I was wrong about RCS Phone app being a conglomerate of several apps in the phone. For some reason I couldn't find the information I needed at that time. I wiped my phone and started over after posting this thread. I was trying to isolate the misbehaving app. I thought it might have been greenify actually, but no the drain has returned to a lesser extent though. Here's some photos of this RCS app from GSAM.

I'm not sure what is causing the drain at this point. I've installed Better Battery Stats to locate the wakelocks so I can ignore them through ADB.

Have you tried disabling RCS ? (Post #6). BBS is good for idle drain, active drain not so much. It's best run overnight without touching the phone for 8 hours or so. Pick the phone up in the morning and create/save a log file as quickly as possible. Post the log to the BBS thread if you need help deciphering.

I cannot disable it since it is comprised of multiple apps. You can see it in the pics on my last post.
