[Q] battery drain issue

For the past week or so I've been trying to nail down my battery drain issue on my epic (fully charged I get 5 hours with light use)
I downloaded advanced task killer free to monitor apps that re running and here's the thing: there are always 10-20 apps running in the background, apps that I didn't open. And when I kill all, they're all back within minutes, some right away. Is this normal or is it the problem? How to fix??
Thanks

There are many apps that run in the background as well as android system services. And yes, many of these will persist in restarting immediately after being killed.
That being said, most are harmless, necessary, and make negligible impact on battery life. What you should do is check out your settings>applications>manage applications and click the running tab. Any app that you recognize that you feel certain shouldn't be there, you may want to consider removing.
As for tips, first and foremost, deactivate Latitude if you've activated it (i.e. sign out). And disable any gps or wifi location services, both huge battery killers when in unnecessary use. Secondly, nearly all widgets will invoke a persistent service that will also drain battery. The only widgets I use are the ATK little android guy and Power Control.
I can go on SyndicateFrozen for 24 hours with medium use, and at least 48 hours with text/phone use only... You know, using it like a phone instead of a laptop .

I'm using 1.1.0 without journaling, instead manually enabling journaling by Nandroid backing up and restoring through CWM.
Advanced Task Killer is my personal favorite, I do not use it on auto kill, instead just tapping my little green android widget every time right before I lock my phone.
Edit: I might add, I'm using VisionKernel, but that I have seen no increase or decrease in my battery life since changing. I do not use SetCpu and instead prefer to let the rom and kernel run under their own defaults.

[Q/ GSM version] Battery Drain due to Media Server

Hi all!
Recently, I updated my Galaxy Nexus to 4.1.1.
I found that the battery drains. Battery level went down 1% per minute.
I did not meet this problem when I was using 4.0.4
How should I fix this problem?
Thanks a lot

Hmm.. same here. Battery Life was better on ICS, that I agree. But JB is really awesome! Anyway, about your problem, I suggest making sure you kill your apps more frequently (Going into MultiTasking and just sliding them all away). This seemed to help me.

I have been trying to figure this out for days. I've read countless threads with no luck. I've got no mhaic , videos or pictures on my phone and its still using a lot of battery. Willing to offer bounty for a proper fix

Just the worst advice ever. You don't need to manage your tasks. If you've got an app misbehaving that's causing drain, you need to uninstall it and use something that's coded properly.

Well that's true. Sorry if I said it wrong. But yes, some apps are coded horribly like Facebook and cause terrible battery drain. So, just uninstall it.

I don't own this device but my battery was draining so fast and I flashed ,, pimp my rom,, and battery lasts for about 2 days (earlier it was barely 1 day)
Press thanks if I helped you

I've shut my Bluetooth off And the drain seems to have stopped

Search the forums and download better battery stats - you can also purchase the paid version from the play store - Run that for a day or so and it will tell you what is eating your battery.
Also, some more information (screen captions, your 'average' use, ROM, Kernel, etc) could help this thread a bit as well.
If you have a rogue app that is causing drain, better battery stats will help you find it.

After I got a program which tests mp3 files and removed all which had errors the media scanning stopped going on forever and killing the battery. I don't know which program off hand but I bet there are several free pc apps to test mp3's online.

This does not kill apps. It merely removes them from the Recent Apps list. If you want to kill apps, you have to go to the Apps manager in settings and force stop. Or use apps that offer such functionality like Android System Info.
---
I also have this issue, but force stopping the medisscanner (or related apps) resolves it temporarily. I'll try the mp3 validation suggestion

Solving of Battery drain Issue
Please check on your device on app which using most of the battery. I used GSam Battery Monitor so that it will shown me the most usage of apps consuming the battery. Just tap on it, tap "manage" then tap on "Force stop".
This accually required on every charge, restart or playing / downloading a media files. Some people suggest clear data on media storage, however, it clear all your custom ringtone and others too. By doing Force stop, nothing will be affected....
Enjoy!!

[Q] ANDROID Experts.. Removing vs disable bloat/unnecessary apps

Can an expert scheme in which is better method and why?
I removed lots of bloats apps from here and feel like my phone drain faster than live them on or disable them. Any experts?

disabling an app disables it so the system knows not to use it. uninstalling an app gets rid of it so it's not physically on the phone. If you want more space on your internal memory uninstall the apps. If your noticing more drain check your battery stats and your data states in system settings. There has to be an app or something doing it. The disabled apps shouldn't because they're disabled.

I use CPUSpy to keep an eye on if my phone is doing odd things. For example the other day my battery was draining like I was constantly using the phone. CPUSpy confirmed that to be the case ... my phone was not going in to deep sleep.
BetterBatteryStats will give you an idea of why your phone isn't sleeping properly (assuming that's your problem). In my case, it turned out to be the Google+ Camera Upload service. It was constantly holding a wakelock, so my phone wouldn't sleep. I hadn't even configured Google+ so I'm not sure WTF it was doing. I froze the app in Titanium Backup and haven't had a problem since.
Also... just IMHO - I don't remove stock apps. Freeze them in Titanium Backup. That way if something goes bad after freezing an app, you can just defrost it and resolve the issue.

I have Cpuspy check for 2 conditions. Both went to deep sleep fine. The difference is stanby time. Even phone is in deep sleep, the % battery goes down faster for Rom with all bloat s removed

Check your cell standby. How much battery is it using. If your phone has to keep looking for signal it's going to use more battery.

[Q] Battery drain on Note 2 after 4.3 update

Hello
I have had a massive battery drain problem on my Note 2, a couple of days after the 4.3 update. While being idle during the night it loses 25% to 30% of its battery and while using it I can literally see the percentage drop. I have tried everything that I could find on the net. EVERYTHING! Nothing worked. These included: Factory reset (twice), letting the battery frain completely and then recharging it while the phone was switched off, switching off all sync,disabling bloatware including KNOX components (the actual KNOX app is not installed), installing only a few apps after factory reset, using Gsam, Wakelock detector, Deep sleep battery saver (which could not make my phone sleep), no GPS, no 3G, wifi on only when needed and more besides.
The phone is only one year old and unrooted. On 4.1.2 it had a beastly battery performance of almost 1.5 days of normal to heavy use, with 300 apps on it. Now it cannot go for more than a few hours with the same use.
I cannot say for sure but it seems to me that the drain is the same when it is sleeping and when I am using it. Wakelock has given me a 75% awake time even though I only use it for 15-20% of the day at most nowadays. Battery settings show everything normal, or at least I think so, eg Screen 35%, Android OS 15-28%, Voice calls 10%, Android system 5-15%, Cell standby 7%, Device idle 4%, Media server 4%. The batttery chart shows a constant steep drop all the time.
The problem started one day when the Media server went mad consuming 50% of the battery. After I did the factory reset it has never again been a problem but the drain still persists.
I have also read that it's a mess up between syncing of Samsung apps and Google services, but I have no way of verifying that.
Can anyone help?
Thanks

I had the very same problem until yesterday myself but think I found a solution on the web.. Uninstall Google Search and Google Play Services and the goto the Play Store and wait for them to reinstall and that's it....! As I found that there is a bug in Google Services (Nlpwakelock and Location service)
Hope this helps...?

Thanks. I already have Wakelock Detector on. I mistakenly wrote "defender" instead of detector on the original post. It gives me Viber and Messenger as the most active wakelock apps. But they both were not installed when the problem started. Besides, on the 4.1.2 they created no problems. In essence I believe that Wakelock Detector cannot help much. Whatever this problem is , it is well hidden. Thanks for your interest and help anyway. Much appreciated.

Which kernel you are using? And also i recommend using Greenify. Widgets usually eat a lot of battery, I went from battery lasting only 8 hours to get my battery use only 30% in 8 hours.
What i did: installed wakelock detector, gsam battery monitor and better battery stats.
Monitorized the wakelocks.
Applied greenify to the apps which were waking most
Removed widgets which were waking alot
Installed Toggle 2G.
Kernel settings: 200-1600mhz | zzmoove | AFTR+LPA | Multicore power saving (SCHED_MC) = 0 | GPU = stock settings
Works like a charm for me. Hope it helps! Any question, ask!

I've read all sorts of things about this problem since I updated and got hit. I have too much app data to lose by trying the factory restore (which by all accounts shouldn't change anything anyway since you'd still be stuck with 4.3)
I finally decided to try the age old blackberry cure-all: "if in doubt, pull it out" (the battery). Since the entire issue seemed to be related to battery caused problems (ie slow charging, fast drain, etc) it made a lot of sense.
And it worked.
I think the main reason this isn't more commonly tried to fix issues on Android is the same reason I didn't try it earlier. My case is pretty serious and isn't easy to remove. I'm glad I did take the time to take the case off though or I could have ended up wiping my phone.

Thank you for the suggestion. I have already taken the battery on and off several times. It had no improvement. The phone is only a year old, that is why I don't believe the battery is the culprit. Besides, problems started only after the 4.3 update. Before that it was working perfect. Too much of a coincidence.

Sorry to hear that it didn't work for you
I'm not saying the battery is faulty in any way - however removing the battery and letting the phone power drain completely seems to stop whatever process is running under the buggy 4.3 long enough for it to work again as intended. It's basically just a more thorough way to reboot.
As I said, I've read all sorts of suggestions, many of which don't work for everyone (such as the factory reset) - this is hopefully just one more thing for people to try before they end up wiping their phone in desperation. I mainly posted here in the hopes that others with this issue that may not be forum members can get some more suggestions.
At least for me, wakelock and all the other diagnostic tools at my disposal showed nothing different to before the update. Many other people have found that the Android System is using a lot more of their battery than normal or some other apps are involved - if this is the case, it's likely to be a combination of things causing the issue (the firmware, the drivers, apps, hidden Samsung processes, etc).
Also, for what it's worth, I found that Knox supposedly wasn't installed (when I find it in the apps list, the button to install it is showing...). But it's showing in the list of apps so it must already be installed. I dug through the list of running processes (had to show the system processes too) and I discovered that several Knox and some other new Samsung processes were indeed running.
One other quick tip - If you wanted to check/tweak the 'developer options' and can't seem to find it any more, that's because it's now hidden since 4.2 - go to 'About Device' and tap 7 times on the Build Number. I tried disabling all background processes however it seems this only disables application level processes, not system level processes but if you've tried everything else, it can't hurt to try playing around with some of the options in there.

Thanks mate
I think you are right. It is probably a combination of many things. I have opened the Developer options some time back. The one thing that I do for sure in there is limit background processes to 4. Besides that I don't experiment much, exept maybe to change transition animation scale. I am actually thinking of rooting the phone and downgrading to 4.1.2. It was just fine before. I can live without the 4.3 add ons.

Here is detail-
Disable sync always, enable when needed.
Disable wifi always scan from settings
Display set to auto
Uninstall apps of playstore you rarely use
Use widgets on lock and homescreen as less as you can (I don't use any)
Disable motion on settings
Freeze all bloatwares by TB except allshare and samsung content agent
Install Agni kernel, from agni control app-
profile: normal
Governor: pegasusq

Don't touch other tweaks, hardly you can tweak sound boost.
THIS GIVES ME A SATISFIED BATTERY STATUS.

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!!

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.
