[q] at my breaking point with battery drain

I know this horse has been beat to death, I'm just hoping I can get maybe one bit of info that will help me resolve this issue before I just swap out to another phone. I really don't want to, but I'm just so sick of being chained to a charging cord all day. My phone should be able to hold a charge for at least 1 day, I don't even use it that much!
So with my little tirade out of the way, let me give you the facts I've got a Samsung Galaxy S II/SPH-D710, and the battery just drains down so fast, and the phone's barely 6 months old. I've downloaded numerous process monitoring apps, designed to see what's going on, and they all point at WiFi being the culprit. The phone never hits deep sleep because the wireless is keeping it awake. Sure enough if I turn WiFi off and I go 3G/4G all day my battery is fine. Problem is I can't get to that next level and find out what program or process is causing the WiFi to be on all the time. Even more frustrating, every time there's an upgrade like FI27 or FL24 which I'm on now, the battery works fine for a day or two. Then something kicks in and destroys the battery. My thought is it's got to be an app, I just don't know which one.
So before I kick this piece of **** out the window, I was hoping someone could please help me figure out what app/process is the cause of my battery drain.

Get DS Battery Saver. It will force all of your stuff off when you turn off the screen so that it will go into deep sleep.

Get a new battery?

Apps, batteries, ics vodoo it's a host of things that can solve your battery drain issue. Being that your phone is 6 months old I have to rule out the battery. The fact that your on ics is going to be main culprit, stock ics was not the best at managing battery use. There's something revving the crap out of your Wi-Fi, while Wi-Fi is on even while your screen is off there are processes going on in the background that are using Wi-Fi to send receive, update, sync, you name it and all you need to do is pinpoint these processes.
Some apps in the play store can help, but some of these apps can consume battery also, so it's best to delete it after troubleshooting.
If your phone is working properly and your not a social media junkie while it sleeps it should not be using any battery at all, just enough to keep your processor awake.
I keep notifications are sync off on my phone, while I'm out and about I'll check email or do a quick sync if I want to check for some incoming whatever. Most of the time I want info on my terms, not every minute with chimes beeps or lights flashing.
If you use google maps disable background location reporting, location services just use "location and search " disable Wi-Fi and GPS usage for location services.
This is a start, but I recommend Jb ga10 stock/rooted to give your phone a stable os.
I run stock/rooted Jb de-bloated with minimal apps, no games (all the games I like are on my Galaxy Tab 10.1) I use my phone for calls........... navigation and media player while driving. I get 16 to 20 hrs on a charge.

I get about 20 hours on the Vanilla RootBox JB ROM. YMMV. I also had terrible battery life on the stock ROM and every other one I tried. This is the first ROM that's bested 10 hours. Again, YMMV.

what rom are you on? tw? cm?

Have you used Better Battery Stats? Or the JB release candidate GB08?

Not to raise the dead, I've just been busy, but this is still an issue for me. I upgraded to JB GB27, and I love the GUI, it’s such a step up from ICS. But I’m still getting **** for battery life. Yes if I use DS Battery Saver it works and I get good battery life. However all those programs cause flaky restart issues. The phone will just restart for no reason. More importantly it’s not getting at the root of the problem.
IRL I’m a computer tech and I can’t just let this go, as previously stated I’m tired of being shackled to the phone charger. I’ve swapped in a new battery, it’s not the battery. I even turned on the setting “Keep WiFi On > Only when plugged in”. That did improve the battery a little, but I still can’t make it through the day without being charged. I’m on the phone maybe combined 30min of phone calls, 30 min checking email, and an hour or so of miscellaneous watching video etc. I know heavy users that are on their phones all day, or let their kids watch Disney movies all night. I’m not that guy, I’ve had numerous cell phones and never have I had one that couldn’t hold a charge all day.
I will be diligent in monitoring this thread, please give me your troubleshooting tips and I’ll report back with the results.

Downlpaf betterbatterystats. And find the wakelocks.

Can do, will let you know at the end of the day.
EDIT: Actually I read multiple issues with SG2 and BetterBatteryStats. However your wakelock comment made me stumble onto the app Wakelock Detector. Again I'll run it and report back. Thanks for the point in the right direction.

Ive noticed no better or worse battery between being rooted/custom rom and stock not rooted. However my phone gets about 16 hours on average. My friend has an epic as well and gets only 10 hours. I feel as though it depends on the user and apps. Facebook is a silent killer. As is any app that uses backround. Best setup ive had so far is billgeryans Quattro Rom with ds and greenify. I pulled a whopping 25 hour minimal use before charge and 13 hour heavy use day.....

With titanium backup. You can also install greenify. It puts your apps in hibernation when your screen is off. So basically it's like freezing and unfreezing. Tbh I think it's better using greenify.

---------- Post added at 07:36 PM ---------- Previous post was at 07:32 PM ----------
so my 2 cents:
1) get a second battery and charger.
2) betterbatterystats to identify "bad" apps and either get rid of them or deal with them.
3) "autostarts" app to stop crap from auto starting on boot that you don't need running as a service.
4) dim screen! huge huge savings. keep it dim enough to use the phone.

Battery issues well I have a solution that won't solve but greatly helps. It's called greenify. It puts all running apps in hibernate mode. It's not like a task killer that just screws things up. U can choose what u want to hibernate and all that jazzy stuff. It's worth a shot. All in all if you want a bada$$ battery efficient rom go with wcx stock rooted rom. It's simply amazing. Hope I was at help

Check out greenify if you're rooted. It removes all currently unused apps and processes from memory, essentially putting them into deep sleep. That combined with ds battery saver and watching your wake locks will drastically improve battery life:beer:

[GUIDE] Insanely Better Battery Life When Idle - Battery Life Thread

UPDATE: Wanted to add from personal experience that these tricks all work on 4.4 KitKat ROMs. This information isn't stale
This guide should work for any Android phone running any ROM. (Though you do have to be rooted for most of these options. Nothing is THAT simple!)
The goal is to reduce your battery drain when your phone is idle. Nothing in this guide will improve your battery life when the phone is in use. But it will keep the battery from draining quickly (actually it will nearly keep it from draining at all) when the screen it off and the phone is not in use. And the battery savings can be extreme! As I write this guide my phone it has been 4 days, 15 hours, and 9 minutes since I last unplugged my Galaxy S4. I have 33% battery life remaining. You can have this too!
These fixes are not your typical "Lower screen brightness and delete carreir bloatware and disable auto syncing" tips. (Though all that stuff is still a good idea)
You can try all of these techniques or just some of them. Some of them will break features of your phone and might not be good options for you. Only you can decide if these fixes are right for you.
Special thanks for Mike216 and Penko956 for the endless research they did Greenifying, freezing, and disabling they did on just about every system and app on thier phone to see what all could be disabled. And to Torbitege who initially helped figure all this out with me for the HTC Sensation.
First off, what's using your battery?
If you're not already familiar with Better Battery Stats, fix that about yourself. Download it. Use it. Love it.
This app will run in the background constantly monitoring what's using your system resources 24 hours a day. It will tell you what apps are causing wakelocks, which are waking the device, etc etc etc.
The app won't do anything to help your battery life. But it will give you the information you need to adjust problematic apps.
Wakelocks and Battery Drain caused by Google Services
The battery saving impact is major.
This is my personal favorite battery saving technique. But it's not right for everyone, so read thoroughly.
Basically Google thinks your phone belongs to Google. Google Services runs A LOT even when you're not using the phone. This causes a ton of wakelocks and wake ups that use battery. I hate that. So I stopped it with a simple mod to the Google Services Framework.
Here's how....
This is a good old fashioned dirty fix, as it breaks some things. Most push notifications WILL NOT WORK AFTER DOING THIS!!!!! So this is not for everyone!!!! You've been warned. Please don't complain later in the thread that you aren't getting new mail or Twitter or whatever notifications after doing this. You're being told up front they will probably not work.
GTalk and GoogleNow (and maybe a few other things) will not work after doing this. Push notifications for any Google apps will also not work. They are casualties of the dirty fix. But if you're like me and never use GTalk or GNow this will help. Some other Google services might not work after this either. But if you're like me and the only Google service you use is the Play Store app, this will not affect you adversely. (Gmail and Google Maps run independantly of the Google Services framework and are not affected at all by this.)
Use this version of the fix for older Google Service Framework installs. You will know if you have a newer version if doing this install doesnt' prevent your wifi and data icons from turning blue (or whatever color your theme uses). If they turn blue, use the newer version below....
You need to download System Tuner from Google Play. The app will tell you to get Android Tuner instead. Don't do it. It doesn't have what you need. The icon is a blue suitcase with tools on it. Thats' the one you want.
First I froze GTalk and Gnow (Google Search). And no, you can't just freeze those two apps without touching the GSF. The GSF will still create wakelocks when trying to activate them even if they are not there. So you have to modify the GSF as well.
Go to System Tuner and select "Start Ups".
Then pick the Google Services Framework from the list and open it. You shoudl see a list of services.
Uncheck the things on the list below. (Basicall anything with GTalk or Checkin in the title)
gtalkservice.diagnostits.gtalkdiagnostics
gtalkservice.connection autherrordialog
talk.talkprovider
checkin.checinservices$reciever
checkin.checkinservices$triggerreciever
checkin.eventlogservices$receiver
gtalkservice.diagnostics.gtalkdiagnosticsbroadcast reciever
gtalkservice.serviceautostarter
gtalkservices.datamessagereciever
gtalkservice.sendxmppreciever
gtalkservices.packageinstalledreciever
gtalkservice.xmppendpointreciever
checkin.evenlogservice
gtalkservice.service.stalkservice
gtalkservice.pushmessagingregistar
You can freeze the GSF entirely with 1 easy step and that will also kill the wakelocks. But the Play Store becomes another casualty if you do that. Disabling the events above will stop the Google Services wakelocks dead in their tracks, and allow the Play Store to continue working. If you want to go that route you can do it but you'd have to unfreeze the GSF everytime you wanted to update an app.
Newer version if you have updated Google Service Framework.
Freeze the Google Services Framework entirely.
Profit.
Note: I haven't personally tried this and can't attest to it's viability to drawbacks. It was suggested by other members in this thread and confirmed to be working by several other people. Your miliage may vary.
One little quirk with both of the above versions is that when you turn on wifi or mobile data, the signal bars don't turn colors. They stay gray because you aren't connecting to the google servers anymore. (They normally change color to indicate that you are connected to the Google servers). After 1 day I stopped noticing they didn't change colors. Now it looks weird to me when I see them colored.
I highly recommend making a Nandroid backup before trying any of this. Once you go that, go nuts! You can't hurt too much when messing with the GSF because it will just shut down google elements. Worst case, you can always just reactivate everything, reboot, and it'll all work like it did before you messed with it. But if you accidentally disable Android System instead of Google Services, you will probably kill your ROM. So back a backup first.
And severely worst case, if you totally louse up your ROM, just restore the Nandroid and it'll all be back to normal in a flash. (Get it? In a 'flash'...haha I crack myself up)
The Greenify App Sollution
The battery saving impact is moderate.
This is one that you're just silly not to be doing.
Get the Greenify App from The Play Store
There is a free version. But its freakin' awesome so buy the donate version. It's $3 and the developer has more than earned it for the way he's making your phone awesome. (The donate version also includes some special experimental features. Read all about it. Do NOT just get the donate version. You need the free version too.)
This app basically lets your freeze any user app when you're not actively using it. And unfreeze it automatically when you want to open it again.
So if you have an app that likes to wake your device and run itself when you're not using the phone, you can just Greenify it and it will be prevented from using any system resources when you're not actively using the app.
You don't want to Greenify everything. Some apps need to run 24/7 like your messaing app, your phone app, etc. If you Greenify those you won't get messages or calls. The app is incredibly simple to us. You just select the app that's causing trouble and tell Greenify to 'go'. And it does the rest. It's just as easy to un-greenify an app if you greenify something you shouldn't have.
Not every app on your phone needs to be Greenified. Most apps behave themselves. Only do this to the ones that are showing as causing wakes or alarms or wakelocks in a battery monitor like Better Battery Stats.
Two that I will suggest for everyone to start with are Google Maps and T Mobile's My Account app. Both of these love to run when the phone is alseep.
If for whatever reason Greenify those apps hinders the way you use your phone, just ungreenify them! Simple as that.
Google Play Services and You
The battery saving impact is noticable.
Google Play Services wakes the phone a lot. It also does a lot. Read more about what all Google Play Services does here.
You have two options for this one. The first option is the nuclear option. Freeze Google Play Services outright. It will never bother you, but it might break some usefulness of other google apps.
The second option, thanks to XDA Member Karpfenhai , is to disable only certain aspects of the Google Play Services. This one uses the same technique mentioned above in the Google Services Framework Section, just different services to disable. (Thanks to Perseus71 for making me aware of this one and asking that it be included!) THIS HAS BEEN RECENTLY UPDATED
NEW PROBLEM AS OF MARCH 2015
The battery saving potential is ABSOLUTELY REQUIRED!
Since Google updated Play Services all hell has broken loose on custom roms. You get a persistent and unkillable wakelock for SystemUpdateManager.
The battery drain is horrendous. Your phone is awake and active 100% of the time.
This affects GPS version 7.0.97
I fixed this by going to the permissions manager (built into many aosp roms. If not available in your rom, consult yoir rom thread for ways to alter permissions) and disabling the permission in Google Play Services for "wake" and "keep awake".
Note: Some phones only show "keep awake". Just do that one if that is the case.
The problem is that on custom roms no ota is available. But Google tries to get it anyway. When it fails it doesn't shut down. It just keeps trying.
If the permissions method doesn't work, try this...

Just so you don't think I'm kidding around when I say you can severely increase your battery drain when idle, take a look at tehse screen shots from my Galaxy S4.
My specific set up is running CyanogenMod 10.1 nightlies with ChronicKernal. I haven't been using my phone much over the past 4 days. I have a total of 2 hours and 34 minutes screen on time and 40 minutes of phone calls during that period. So this is admittedly very light usage. But that's perfect to show you that these techniques really work to minimize battery drain when the phone is idle. And I promise you that your results will vary based on your ROM and Kernel.
This won't make the battery last longer during use. The screen will still burn a lot of battery and the cell radio does too. But if you want to make sure your phone will be charged when you need it without you having to carry a charger with you everywhere you go, these are the mods for you.
As you can see from these screen shots I am at 4 days, 16 hours, 50 minutes since unplugging. I have 31% battery left. (That's what the 31 in the upper left corner is. Thats' from an app called Big Battery Notifier. Its free on Play.)
The other screenshot is from Better Battery Stats showing my Alarms screen. Alarms are loosely the same as wakes. Everytime an app wakes the device (not neccessarily turning the screen on) it will record an alarm. If you look at your BBS alarms screen without these modifications I bet you see a lot more alarms than you see here, and keep in mind that mine screen show is showing 4 and a half days worth. Each one of those represents an app or service waking the device and using battery.

If the written instructions somehow baffle you, here's a video of the whole thing!

This will show you step by step how to do all of this.

Just a note. If you convert Google Play Services to a User App (TB), you can then Greenify (free ver.) it. This works very well and does not affect other functions that may rely on that app.
I also Greenify Maps and Google Search. Two more heavy drainers. Convert to User App first.
*Note: You must use Greenify v1.82 to Hibernate Google Play Services! Search this thread for links to it.
Fwiw, my sleep drainage is 0.3 - 0.4%hr, with wifi on 24/7.
I get either 7-8 days standby, or so far, 5.5 days with 3.5 hours screen time, or likely 6-7hrs screen time single day. Screen shots are in my posts.
I would argue too that these settings/tweaks do indeed increase your battery time, since while sleeping, the battery is draining at a much lower rate, therefore keeping more juice for live time use.
Although you and I don't use all of the same "tweaking" programs, we do seem to be on the same mission. Better battery life! :good:

It does. It also allows other functions to still work such as TTS. I had the issue a while back. Something to do with shared voice.
I also freeze Contacts and Calendar syncs as well. If I want them to sync I simply thaw them for a few seconds.

Maybe one of the "gtalk" options has something to do with notifications because last night I rebooted my phone a lot checking/unchecking options, none of the "checking" did anything! So that's good, and I unchecked some gtalk but not all and it worked!

Btw. I forgot to mention that after I reboot the first thing I do is turn off Google Play in Running Programs. Persistent bugger. And of course I turn off notifications and auto update in GP as well with each new ROM install.

[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...?

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 defender, 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

Download wakelock detector from the play store. It detect which app is waking your device (both screen and cpu) by list.. Then download greenify from the play store and herbinate (greenify) upper most apps from wakelock detector. Hope you can solve your problem

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.

The only battery apps on my phone are the 3 mentioned above, so I don't know what the battery monitor that keeps my phone awake is. The drain existed before I installed these apps. I have read that Chrome could prevent the phone from going to sleep but it is disabled on my phone.

I faced same battery drainage issue, after installing wanam kernel and freezing all bloatwares through Titanium Backup. I'm satisfied with my battery now.
You can try.
Sent from my GT-N7100 using XDA Premium 4 mobile app

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

Best battery saver when screen is off.

Hi! I would like to know what are some good apks for saving battery when the screen is off. I have greenify right now and it works great. I have tried deep sleep battery saver and du battery saver and dont work much for me. I have great battery life but would like to extend it more when screen is off/locked. Thanks!

Get Skyhigh Kernel (root). All the rest is placebo.

Battery life is related to usage patterns, short of underclocking; no app can help you there. Turn off WiFi, Bluetooth, NFC and all crap you don't need, and turn them on ony when you need them. Change your screen timeout, so it turns off quicker when you put it away.
My ultimate battery saving tip is power off the tablet when you don't need it.

Xposed module Unbounce for screen off battery life.

Thanks guys I use Greenpower now and it does the job. I just wanted something that would disable wifi or gps when Im not useing a certain app after 10mins.

It's mostly sync and/or location. Turn those off and your tablet will actually sleep (and wifi off when sleeping setting).

My Tab S can go weeks with just a tiny % drop. Just disable all the Google crap, there are many threads on it. No greenify or other apps will do as much for your battery life.

Thanks for the tip! Yeah I stopped useing battery saving apps since drain more of your battery. I use greenify to hibernate most of my apps and only wake up till I open it. I will look into disableing some of the google stuffs. Lol I use the bing search app instead of googles.

On my old phone (2.3.4) I used Task Manager from ES
Do I understand you right, that we need both tools you suggested, because there is no "autostart" app that also disables services ?
Could you please give us an idea/list of disabled services and autostarts

The autostarts app just disables apps you dont want on when you just turned on your tablet. They still work when you open them. But for services, there are too many.

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.
