Extreme battery drain on extended battery

Please bare with me, I am a fairly novice xda user.
I purchased my Bionic at launch, and it has been working perfectly until about a week ago. I always run the phone on stock OS not rooted, automatic brightness, 4g turned off, no wifi/sync/bluetooth. I would generally get down to 20% of my battery from 7 am to midnight on these settings, which was fantastic.
Suddenly, I now lose 10% every 20 minutes. This is not an exaggeration, I have been testing it with Battery Spy. CPU Spy reports that my phone never goes into deep sleep and is always running at the lowest mhz setting when idle.
Under battery usage, Cell Standby is reporting 45%, then Phone Idle at 35%, then Screen at 15%. The remainder its split between K9 Mail and Handcent SMS.
I have uninstalled everything that I thought could be causing this... Facebook, Google+, etc. Apart from the stock bloatware and k9/Handcent, my phone is like new. The best I could do is a factory reset at this point...
I don't think it is a bad battery because the stock battery goes from 100% to 0 in less than an hour when it would last half a day beforehand. I am really at a loss.
One thing I do know is that the 3g and bars are almost always blue, which I think it means is transmitting data. Maybe this is the culprit?
Please pardon my ignorance with the whole issue. Any help would be very, very appreciated. The Bionic was the best phone I have ever owned up until this battery fiasco, and I would like to find out why this is happening.
Thank you.
EDIT: would just like to update, Battery Spy reads that my phone is running at 104° Fahrenheit. I do not know if this is normal, but this was after an hour since a cold boot. Sounds high to me but I'm not sure.

Sounds like you have some thing that is really using up some cpu cycles. One way to see what's going on is to install the app Android System Info from the market. It has a section called Tasks and it will let you look and see what part of the system is using how much cpu. I do not think you have to be rooted to use this, but I could be wrong. I did go to the market and look and saw no mention of needing to be rooted.
I know this will sound extreme, but I would definitely do it if this was happening to my phone: Factory Reset and start fresh.
Good luck.

Thank you for the advice. I installed it, and appear from the Android System Info app taking up 50% of my cpu, and Android System using 4%, everything else was listed at 0.

Well, that didn't help much. Oh well, I would definitely do the Factory Reset then. Again that's just the way I would handle it as something is going on with your phone that wasn't happening earlier. Just go to the Privacy settings and make sure you have Backup and Automatic Restore checked. If your launcher has a backup feature, go to preferences and do a backup of the launcher settings. Then do the Factory Reset. It's a pain to have to setup everything again, but a reset really does cure a lot of ills that pop up.
Good luck.
Oh BTW, here's some general Battery saving suggestions:
Battery Life – BY: NoBloatware on DF
consider doing a factory reset. Do not sync apps, wifi connections, etc. with Google services as that may cause a problem. Install all apps and wifi connections from scratch. A bit of a pain, but not too bad.- install a home/launcher replacement. I use Go Launcher EX, which is free, and I love it. No reason not to try out an alternative launcher as you can always go back to how you had it.
- don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can.
- don't use antivirus
- the DLNA app pops up a dialog box that will set your WIFI sleep policy to never. The default is "turn off when screen turns off" and I personally think that this setting is the best thing for battery life. Under wifi settings view your connections then hit menu to see "Advanced options" where you can set the sleep policy
- if you have access to wifi, leave it toggled on as it is more efficient than 3G. This is different from the sleep policy.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- when you get a new battery, do a factory reset, or an OS upgrade run your battery all the way down until the phone shuts off and then charge the battery all the way up. This will callibrate the phone's understanding of the battery's capacity. Do this once every month or two also, but don't do it too often if you can help it.
- I have my battery set to "Performance Mode" and data is on all the time because I am on call 24x7. If you don't mind, try out a more conservative battery profile to save more gobs of energy.
- set screen brightness to "Automatic"
- under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
- if you never use bluetooth then toggle it off. If you do use it sometimes, it's fine to leave it toggled on all the time.
- consider turning off voice privacy. This may not be a big deal but it will save some processing (and therefore battery). It may also improve call quality.
- turn off haptic feedback, animations, and any un-needed sounds in Android settings and in your apps
- set your screen timeout to as low a time as you can stand (I use 1 minute) and manually turn the screen off when you're done using the phone. I use an app to lock the screen so I don't wear out my power button...as happened on my original droid.
- turn off in-pocket detection
- keyboard: turn off vibrate on keypress and sounds for any keyboards you use
- use a red screen background. On the original Droid screen--not sure about this Droid 3 screen--red was the most efficient color that could be displayed. Anyone know if this still holds true?
- camera app: i like keeping location on and flash on auto. Consider turning location off or at least returning to the home screen ASAP when using camera if location for camera is on.
- in stock browser the default home page is Google and it uses your location. This is a bad idea as it can waste your battery for no reason. Make something else your home page and make sure to close any web page that uses your location when you're done viewing it.
- charge your phone via the wall charger instead of computer USB as it is faster. Also, don't use long USB cords--use regular power extension cords instead. I stick with the charger that came with the phone.

Format the sd card in ur pc. Then put sd card back in bionic and transfer ur stuff back on it. Ur bionic is scanning sd card non stop for errors drainin battery. I had this problem for weeks beofre i figured this out. Was gettin 7-8 hrs on ext battery. Now ibget 30 hrs

I had a similar issue and the problem was my sim card needing to be reinstalled. It was not seaded correctly and caused my radio to act up. I truned off the phone and removed the sim card and then reinserted it and rebooted and I was back to normal.
I am not sure if this is your problem but it is easy enough to try.

Would this apply if I am not using 4g? I have 4g disabled and it was my impression that the sim card was only used for 4g.
I uninstalled k9 which for some reason began using 7% of my battery though I had never opened it since reboot and now I am getting a loss of 10% per hour of normal use.
I went to bed with the battery at 70 and woke up with it at the same so I at least solved the sleeping problem. Not sure why k9 was responsible though.

Stock Battery Performance "Fix"

History: as aprevious iPhone 4 user but long time android tablet user, I was less accustomed to battery consumption on Android phones. I was experiencing sleep usage (data on, WiFi connected to home network and good signal, Bluetooth radio on but not in use) of approximately 6-10% per hour. After reading battery life posts from other users on these and other forums, it appeared this was excessive. I had, after enabling these items (Google now, Google +) decided to disable them. But usage varied little. On screen time was about 3:40 or so. I had Google voice and Pandora installed. I was using built in email client, 3 accounts, fetching every 30 minutes including 1 @gmail domain account, what's app running, skype installed but not running or notifying. Battery usage stats indicated nothing excessive, Voice, What's App and Pandora had a process or two running along with WWF and SWF (notifications set for 1 or 2 hours) but batt stats did not indicate anything unusual with OS. Pulse, AP press, Flipboard installed but set to only sync/update when using the app.
First fix attempt: installed juice defender and set to aggressive. Battery use dropped to 3%/hr when left untouched for the hour. Emails weren't coming through regularly because of the JD and email client timing off sync. Installed K9 and set to 10 minutes fetch for all three accounts. Battery usage about the same for on screen. Better performance. Could get through 10-12 hour day with moderate use texts, emails, news apps (pulse clipboard ap) and a few pics. But battery drain seemed to be drastic when using apps and the unit started to drain when idle at a rate of about 4% (could be signal cell tower location cgange , etc). Overall acceptable but still "less" than when compared to forum posts and previous phone experience.
Second and present attempt: installed wugroot toolkit 1.6.2. Unlocked boot loader, rooted phone and installed custom recovery. Returned to stock. Rerooted and relocked. Installed no accounts on reboot. Installed Google account afterwards with same calendar and contact setting auto sync only. No Google +, no Google now, NO Google voice. No gmail. No pulse no clipboard no AP. Researched and installed Taptu in lieu of Pulse. Installed Aqua mail as email client for three email accounts(at least now I can change the account an email is sent from after beginning to compose an email!). Reinstalled Evernote, drop box, Google drive (manual sync for all three). Did NOT reinstall Juice Defender.
Battery use, when left untouched for an hour is almost NIL! (Still says charged) After 2 hours phone is at 98% or 99% when before it could be 82-88%. This is a revelation. 35 minutes of playing granny smith consumes 10% of battery, interpolation (all I can go on at this point) would mean almost 5 hours of constant screen use and less with standby time . WiFi, data, Bluetooth (not in use) enabled. NFC disabled and same settings as mentioned above.
Explanations: Google voice could be a severe drain, but I will not install yet until I am convinced it's innocuous as I am afraid an install and uninstall could "mess things up" with the OS. OR Google + and Google Now can not be installed and then uninstalled without leaving something running in the OS contributing to battery drain. OR pulse, flipboard and ap are not behaving well in manual sync modes.OR the wipe and reinstall via Wugroot has eliminated a bug from original factory setup. Regardless, the phone battery use appears in line with the positive experiences of those in these forums. I suggest, as much of a pain it might be, to give this a whirl if you are technically inclined. Please note all data will be wiped by this process and while I backed everything up via wugroot in case of a disaster scenario, I did not restore ANY data from those backups for the reflash of 4.2.1 and reroot, relock process.

Don't use juice defender, only does more harm than good.

It is actually a last resort for those whom are unauthorized, intimidated or unsure about reflashing the OS onto their device. Therefore, while it may do more harm than good on a device with little issue (i.e, no software apps or OS bugs), it actually helps those with such problems until they root out (couldn't resist) the source of the problem and move on. Again, reread my post as I discontinued its use after the reinstall of the OS.

If you havin' battery troubles I feel bad for you son...

I got 99 problems but my battery life ain't 1.
How to get the best battery life out of your Nexus 5
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
11. Greenify: Works with and without root. Use Greenify to hibernate apps when they should not be running in the background. This is best used for games that fetch information about deals or daily events (i.e. Battle Nations or Real Racing 3)
Feel free to add anything to my list.

4, 6, and 7.. it would all depend on your signal quality. i get MUCH better battery life on lte than on wifi. and i mean much! i get 5-6 hour screen on time without doing anything special. on wifi i get an hour to hour and a half less. so the wifi thing is just in your situation, and not for everyone.
9.. there are better kernels than franco kernel. and on top of that, kernels have so little influence on battery life. battery life is mostly about your personal use, your personal setup, your choice of apps used, and very much on the quality of your phone/data connection. everything else has very little influence, including kernels.

3. This I agree. I've had super strange battery drain if I don't restart the phone once in a few days. I refuse to believe its a bad app as there are no wakelocks, seems to be more of a phone idle battery drain or radio drain.
4. To be honest, it depends on the WiFi network. Some WiFi networks (typically at universities) have a strange and outright horrible battery drain the moment you connect to their network and leave the screen off.
6. Again to not repeat what I said earlier, I get better battery life if I connect to LTE instead of my school's WiFi. Download speeds over LTE are 2-5x greater than my school's WiFi, so race to idle may be happening here.
7. Most android phones today have minimal battery drain with WiFi left turned on. But it doesn't hurt turning WiFi off if there are many weak known WiFi networks around you.
8. Not sure how much you'll save, I don't even recall much of an increase of battery with this off. YMMV situation I suppose.
9. I've had better battery life with other kernels. Again it's a YMMV situation.
Not a bad guide really
Another tip is that if Google Play services keeps your phone awake for a long time, revert Google Search to an older version, reboot the phone. The wakelocks should be drastically reduced.

Using Nexus 5 with:
CyanogenMod Nightlies
ElementalX kernel
1d 2h 9ms on battery / 2h 17ms screen-on time / with 38% remaining!

Good information! ?
Only thing I'd say is to just remove the part about kernel completely. As said above, kernel makes little difference. I get 24 plus hours and 6 hours screen time on any ROM or kernel. It's all setup and usage.

Nothing new here. Good for noobs, but most will have done this already

I have found that turning location off completely has helped my battery life tremendously. While I was barely able to make it through the day before, now I can easily pass by with 40% or something and light usage. I've tried other things but nothing has improved my battery life as much as turning location off.

Yup! That's what toggles are for. Need it? 2 clicks and its on. That's always my advice.

[Q] Still chasing battery drain: Is it possible FingerPrint Unlock is part of it?

So having come from Verizon's Note 4 and averaging up to 24hrs on battery running pretty much the same setup as I do now on my T-Mobile Note 4 minus the "Root" & "Custom Rom" abilities. Otherwise, same apps, accounts, usage pattern, ect...
I am on an ongoing battle still after several complete wipes, different Roms including just running STOCK ANK4 and trying to figure out what is going on. Phone defect? Battery defect?
Anyhow, Ever since changing over to both the T-Mobile Note 4 & their service, my experience has been a rather miserable 14 to 18hrs MAX battery life and going from 4hrs screen on time to around 2 1/2 w/ T-Mobile.
Which now leads me yet to wonder something else. I believe I started using the "FingerPrint" security feature since switching to T-Mobile to unlock the device. Has anyone experienced a similar "Battery longevity" issue using said feature before I continue troubleshooting and chasing my own tail on this? Of course I will eventually test this theory anyhow, but figured I would throw it out there.
Also, Open to any suggestions.
Just some things I have already done along with the above mentioned:
- Utilized the App "Greenify" & donation full version to greenify many apps including "Google Play Services".
- Set up Profiles which I toggle via "PhoneWeaver" to turn off data when on Wi-Fi which consists of 90% of my day as I'm Wi-Fi connected both at home and work.
- Of course always turn off that option within Wi-Fi settings to untick "Always Scan".
- Went into "Google" app settings and turned off about everything I can find in there and it's now rather complex settings.
- Turned off most syncing of my 2 "Google" accounts to only one having anything other than Email Sync active such as the Calendar, Contacts, and Apps Sync. - Again, my 1 Google Account I only have set to sync Email and nothing else.
Sure I forgot some things I've tried but again, I am open to any/all suggestions. I admit, I bought my T-Mobile via Swappa. All seemed well as per their checklist of the obvious things to check regarding the phone's operation. Kind of stuck here now and wondering if my device is simply defective and/or the battery.
Also of note: Android System is always by far the largest contributor to my battery drain and exceeds even Screen-On time by around 10%. But then again, don't really know if that means anything or not since even before switching carriers and the transition from "JellyBean" to "KitKat" on my previous S4, Android System became a forever battery hog for me.
Just never had a top end device such as this in past years barely get me through a complete day: Work & Home time. I don't consider myself a heavy user. Barely even "Moderate" many days as I mainly text during my lunch break, otherwise phone is pretty much idle. And say 2 phone calls of aprox 20 min.s each during commute time. Yea, something just isn't right. :crying:

I have noticed 3 things that were hurting battery bad.
1.) Use the Google play services with the 030 extension. I get way better battery life on it 5% to 10% increase in battery life. Link below:
http://www.apkmirror.com/apk/google...ices-7-0-99-1809214-030-android-apk-download/
2.) If you are not using maps or other location services turn your location off. Literally a 20%+ increase in battery from this alone.
3.) Toggle your NFC. Something in Android 4.4.4 sometimes causes your NFC to wake lock. If you turn it on then turn it off one time it normally fixes is.
I attached my battery stats below.
It with about 2 hours of screen on time.

Thanks for the reply and suggestions! I just checked and I am currently running Google Play Services V 7.0.97 (1791429-030).
A couple things I have done meanwhile since my OP which have had "some" noticeable positive effects on my battery duration, yet still no where near what you have posted are:
Within "Google Settings" app:
- Account History ( I have "turned off or rather paused" ALL the Activity/Info/History settings here - All 5)
Regarding my 2nd, basically "Junk mail" Gmail Account:
- Now have ALL "Sync" turned off within, including the syncing of email, which I now simply check manually to update.
Greenify:
- Revisited, and added a bunch more apps and pretty much "Greenified" ALL Samsung related entries/services/ect...
So far I have increased to achieving up to about 3 1/2 hrs Screen time (Gained 1 hr) & a few more hours of real time battery longevity as I can now achieve close to 20hrs before needing charge.
Still feel I have some troubleshooting to go. Oh, I actually have the NFC Service "Greenified" to. So far haven't really noticed a problem with "Deep Sleep" either according to CPU SPY pro.
Yep, Have always had the Location Service to OFF, not even using the so called "Battery saving" selection with it. Such a pity to have to cripple such things but it's a trade off I guess in achieving a full day's battery vs.s using the features with this phone for some reason more-so than past devices it seems. At least in my case. :silly:

Battery preservation strategy

I've been thoroughly impressed with battery life on the Moto Z as a result of normal use. Less so with idle battery consumption. That is, after installing my full complement of apps (including facebook and twitter), I did a few tests by going too bed on a full charge, and found that 7 or so hours later, it had burned down 15-20% doing nothing overnight!
I installed gsam batter monitor since the stock one is kind of useless. This provided a lot of valuable info, which is basically that Twitter is a huge hog, Facebook surprisingly isn't, and google play services also seems to be spinning its wheels a lot when I'm doing nothing. But most of my juice was going to powering the wifi radio.
Android M has a setting to turn off wifi when the phone is sleeping. I was reluctant to do this at first because I figured my apps would just start wasting my data instead. However, you also have the ability to selectively limit apps' ability to use cellular data when running in the background. In an app's settings you can click "Data Usage", then "Restrict app background data."
I did this for all the apps that gsam identified as being the wifi/battery users. And frankly there are almost no apps that I actually want using data when I'm not using the app itself anyway, except SMS and gmail. (I wish there was a way to just say "actually shut this app down when I close it", so I could activate it for most apps!)
Anyway -after doing this, I activated the setting to turn off the wifi radio when the phone was sleeping.
Result? 2% battery drain overnight, and minimal cellular data use. Amazing.
(Btw - I also uninstalled the twitter app and just put a link from chrome on my desktop. The web mobile app is very good anyway and I'm not much a twitter addict so this is a fine alternative that is a lot less intrustive for me).

But most of my juice was going to powering the wifi radio.
Android M has a setting to turn off wifi when the phone is sleeping. I was reluctant to do this at first because I figured my apps would just start wasting my data instead. However, you also have the ability to selectively limit apps' ability to use cellular data when running in the background. In an app's settings you can click "Data Usage", then "Restrict app background data."
I did this for all the apps that gsam identified as being the wifi/battery users. And frankly there are almost no apps that I actually want using data when I'm not using the app itself anyway, except SMS and gmail. (I wish there was a way to just say "actually shut this app down when I close it", so I could activate it for most apps!)
Anyway -after doing this, I activated the setting to turn off the wifi radio when the phone was sleeping.
Result? 2% battery drain overnight, and minimal cellular data use. Amazing.
(Btw - I also uninstalled the twitter app and just put a link from chrome on my desktop. The web mobile app is very good anyway and I'm not much a twitter addict so this is a fine alternative that is a lot less intrustive for me).

I just got the phone a couple days ago. I appreciate the info here. I have also read that if you just turn wifi to 2.4 GHz only that it will keep the battery drain from happening. I don't use twitter or facebook so don't have to worry about those. Google play services has been a problem since marshmallow. If we could root we could use something like Amplify to stop all the wakelocks, but root is getting hard to come by on these new phones.
I noticed on Gsam that my phone will sleep well for a while, then the "held awake" category starts to take off. I have to reboot to get it to doze again. I have agressive doze and doze on the go activated in Greenify. Not sure what gets it started, but it would be nice to be able to kill it off without rebooting.

I bought a USB C to regular USB and have been charging without the Turbo Charger and the battery is doing so much better.
I was getting frustrated with the battery performance.
