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.

i have the same problem man! i have the extended battery and it lasts maybe 9 hours and i have tried several batteries from verizon store i keep swapping them lol and im on 4G all day and performance battery and data on all 24/7 too and i could get 20 hours ++ out of thunderbolt extended and cant get half that with bionic. there is something going on and nobody at verizon can figure my problem out!

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.

[Q] "Android OS" Taking Up My Battery

I have used the Droid, Ally, Galaxy S, Galaxy Tab 10.1, Droid X and many other Android devices without this problem. This phone is different. Android OS has been taking up 25-30% of my batter with everything I do. Complete restore, update, custom roms, etc, nothing works. I averaged on my other devices well under 10% of my battery being used for Android OS, but this one uses a crazy insane amount and my battery is dead in 7 hours on 3g only mode! What's the deal?

That is a lot. The most i have seen is like 10%.

I only have 4.5 hours of uptime right now, but mine shows 4%.

4% here.
You have something installed that's using the "os", or some app that relies on a service that is now gone.

if Android OS is that high then you're basically doing nothing with your phone.
Try watching a NetFlix video for an hour, or else playing a game, etc.
You have to realize that your phone never actually turns off (else you'd never receive phone calls ) so that the OS has to be running.
If you're doing nothing, just letting the phone sit there idle, then of the 5% of the battery that you let it take up while you were waiting to see if it went down, 30% of it was consumed by the Android OS. It makes sense if nothing is being used that hte OS itself will be the largest user of battery, b/c, as I mentioned, the OS is still running, even if in sleep mode.
And, TBH, it actually made more sense that the old way of reporting Cell Standby was taking up 'so much' battery - b/c if the phone is idle, then I expect that the phone call monitoring aspects of the OS would take the greatest amount of battery, b/c nothing else is using the battery.
You have to take what you see in battery usage with a grain of salt. If you're not using your phone and you see a 3rd party app taking up 40% then you have something to worry about. If the OS itself is taking up that sort of percentage, it means nothing else was running ot take up the battery.

I agree with John that non-use will cause OS to seem abnormally high.
However, your 7 hours of battery life is terrible:
If you are having short battery life here’s a list of things that can help. Just read through the list and select the items that fit with the way you want to use your phone. Not all items will work for everyone and this list was written for the Droid Bionic but should work for your phone too:
- 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. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- 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.

- 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’ve finished using the phone.
- Turn off in-pocket detection. In-Pocket Detection has been the source of many issues already.
- Keyboard: turn off vibrate on key press and sounds for any keyboards you use
- Use a red or black screen background. On the original Droid screen--not sure about this Bionic screen--red was the most efficient color that could be displayed.

- Consider install the Home Replacement app Zeam. It is basic app that uses very few resources and will help with battery power.
- Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail.
- If you are using Live Wall Papers, stop!

If battery life is still bad: Consider doing a factory reset: These have gotten pretty painless lately by following these simple steps: 1. Make sure Backup and Restore are checked in the Privacy setting. 2. When going through the setup after the reset, turn on wifi as soon as you can (assuming it is available). 3. After you have entered your Gmail account info, you will be presented with a screen that has two check boxes. Basically they are "Do you want Google to backup and restore this phone”. Make sure you check both of those. Your apps will then automatically reinstall (paid and free). Set the phone aside for a minute or two and let the apps download and install. 3. If rooted, use an app such as titanium backup to restore data only to select apps such as Tapatalk and you will not have to re-enter all your login information. I do this for 3-4 apps (Tapatalk, SPB Shell, etc.).
I've been flashing new roms/updates about once per day lately and I can be up and running with all my apps and settings back in place in less than 20 minutes. It's pretty painless now.

When I first bought my Bionic, it was eating up battery like crazy. After 2 replacements phones, I found out that some Bionic's were having an issues with Draining battery. My 3rd Bionic is great. On my original Bionic, it would take me 2 extended batteries and still could not make it through day under moderate use. Now, 1 extended battery will last me all day with heavy use.
There are some faulty Bionic's out there. It was even mentioned on Droid-Life. I think the original one they tested had issues with battery drainning really fast.

That is weird. I wonder....could it be due to actual batteries as opposed to the phones?
But in the OP's case, I doubt it - it would be too coincidental that his battery were to fail right as he applied the update.
@OP - you might also try conditioning the battery, fully charging and then running it down a couple of times and seeing if it stabilizes. It might have to do with the update wiping the stored battery stats (long shot, I know, but still)?

Droid 4 battery issues...unbearable.

I spent a few hours looking through other threads, but nothing seemed to quite fit my scenario.
Stock droid 4 with the latest over the air update.
I use the phone very sparingly during the day, and my battery drains very quickly...
Usually take off the charger around 8am and battery is below 20% by 2pm.
My usage is usually one or two 5 minute calls, and probably 10mins of facebook.
Is there a good smart action I could try?
I had one that turned off the 4g while the screen was off, but it made sending picture messages unbearable...
My battery use indicator blames screen, then OS, then facebook....
I feel as if it's not reporting the culprit correctly...
Any help is much appreciated.

I've had similar issues, not sure what I did to cause them. When I first got the phone, 16hrs+ with what I would consider moderate usage was normal. I've flashed AOKP and the battery life is back to normal (on track for 15hrs today), but the stock rom is a disaster.
I'll let you know what I turn up (if anything), but I have a feeling I'll probably be wiping everything out since I actually like the stock ROM (plus no hw accel in ICS).
Edit: Also, how did you have a smart action turn 4G on/off? I was under the impression we can't control that at all, except via system menu. Is a downside to VZW's 4G...

I believe that was actually via the app Juicedefender.
even with it on i was still only getting about 8 hours...
I am semi interested in rooting/flashing a rom etc, but my last experience there was a disaster(thanks to a ****ty droid eris)

I disabled all widgets except for facebook, being that it's the only one I use...
The only non essential apps running all the time are battery circle, and facebook(widget i guess?)
I'm now charged to 100%, gonna see where these changes take me.

What are your settings as far as Brightness, Haptic Feedback, Screen Timeout, Vibration (Incoming Message/Call or End Call). Also, I recommend just using the FB app instead of the widget as I notice most of the widgets draw power even when the screen is off.
I am currently running Eclipse 1.3.7 w/ xrjxMod, Brightness all the way down, all vibration and haptic feedback is off. Since I am rooted I also used ROM Toolbox to adjust my scan interval to the minimum. I have the screen timeout to the max, but I always turn it off manually after use. I am constantly on either FB, XDA, txt messages or the occasional game/Netflix use and with the exception of watching a full episode or movie on Netflix, I am averaging about 6 to 8 hours on a full charge.

My battery is now sitting at 46%.
Since my last post I used the phone for 18mins of phone calls and nothing else.
The breakdown is 46% voice, 23% android OS, 12% display, 9% phone idle, 8% cell standby...
The brightness is as low as possible, haptic feedback is off, phone is set to vibrate(thats the only way I get calls)
All three location settings are on....Should I turn them all off? I dont know which are important...

I agree with azreal. Check your setting. Haptic feedback sucks up juice and unless you like it is more of an annoyance imo. There is an option for it in language and keyboard as well as in the screen menu for your soft keys.
Do you have your gmail setup to constantly sync? If its not needed un-check it in you accounts menu.
Are you leaving wifi on when your not in range of a remebered router?
If you are not in a strong 4g area set it to cdma only in your wifi and networks menu.
My opinion of apps to extend battery life is a negative one. Its an app that always runs to make things stop running???? Some work ok but most do not.
If all else fails I would suggest the eclipse rom for the d4. As long as you are safestrapped and follow directions properly you can't go wrong. In the case of a bootloop shut the phone off and reboot and you will come back to the recovery screen to try it again or go back to stock. Its nearly foolproof.
You may also want to do a battery stat wipe if your still having issues. Just discharge your phone completly, then fully charge wipe stats and completly discharge again then fully charge once more, and see if you notice a difference.
I get around 15-16hrs on stock and up to 22hrs on eclipse (varies with usage) by following these few things.

I have wifi permanently off...
I have 4g almost all the time.
I use a gmail, but I cannot find a way to limit it's syncing...I still want it to check for emails, I guess just not as frequently.

I would hazard a guess that having 4G on all the time is one of the main culprits. I leave 4G off unless I am browsing the web, forums, or something else where the extra speed is nice. I use the 4G Toggle widget from the market to turn 4G on and off. I always turn it off before hitting the power button to turn off the screen. No need for it to be sucking juice when I'm not actively using my phone.

I just installed the toggle switch, I'm gonna give it a go.

To turn off the gmail sync go to accounts click on you tap the account. Then uncheck the sync box.
When you want to check your email go to the gmail app hit the menu and sync. Takes about 30 seconds extra but saves some battery.

I'm always skeptical when people blame gmail sync or 4G on battery issues. When the phone was new on stock, and on ICS now, I have three gmail accounts, a yahoo account, and one Exchange account all syncing in the background + 4G on 24/7 and getting around 16hrs of battery life. This was the case for weeks. Then I started having trouble with Verizon's Backup Manager, did a factory reset, and now stock battery life is ~ 8hrs, with 4G OFF
I'm thinking at the very least, there is an issue with the stock battery information panel. My feeling is it hides battery use by the stock bloatware...

I agree that there is probably more to it than just 4G or syncing. Especially where people are getting only 8 hours or so battery life. I personally have noticed definite battery savings with 4G toggled off when not in use though. I can usually still go most of the day even with it toggled on all day but with 4G off, except when I actually need it, I usually get to bed with 30% - 40% battery left as opposed to 10% - 20% left with 4G on all day.

I would also turn all 3 locations off. No need to run the gps when not using navigation. I keep my 4G on as I use it frequently but I am going to try the toggle as well for the extra savings on battery when not netflixing/browsing.

Yep. I'm also having big issues with my Droid 4 battery. First I thought it was the firewall. But even after uninstalling the app, the drainage is absurd. The battery drains so fast, the phone gets warm.
I don't know where to look. I read something about logcat in another thread but could't find it anymore.
My Droid 4 can work about 5 hours on one battery charge. No gps, no 4g and no wifi. If I turn on wifi, it lasts about 8 hours, so I'm suspecting that some process loops when in non WIFI mode.

If you're out of options try using an app called watchdog. It let's you see if there is an app that's draining your battery unusually fast.

Thanks for the tip. But what whatchdog should I use? There are many apps called watchdog

Watchdog task manager lite (free version).

I tried that this morning. Still poor battery life on stock, but watchdog doesn't flag anything. Very weird
Oh well, I would definitely recommend AOKP for anybody having battery problems.
For me today: 4 hours 55 minutes since unplug, 80% left.
Screen time on: 50 minutes (!)
That being said, I do keep my screen on pretty low. Still, you can tell I've been using it...

Watchdog couldn't help me but. My data monitor showed that motorola.services was generating a lot of data the past few days (800+ MB :O ) and responsible for the battery drainage. I blocked it with droidwall. It's better now, but sometimes it still pops up and generates data despite the fact it's blocked.
So glad that I have an unlimited internet plan or else I was really screwed

'How To Get Better Battery Life' tips and tricks

I haven't seen one of these threads yet, and I think it will benefit users of our D4 forum.
If you have any tips/tricks, feel free to add them here.
My first tip: TURN OFF 4G AT ANY TIME POSSIBLE. 4g is a battery vacuum.

Here's the biggest....Widgets and Social Networks.
Watch your widgets (weather, news, facebook, etc..) that update/refresh. Most will allow you to adjust the refresh time. Set it high or to manual refresh.
Social Networks.....set them to refresh only. You don't need them refreshing their data in the background, just have them pull the latest down when you are actually using them (Facebook, Twitter, Google +, etc..). Set to manual refresh so that they only refresh when you are using the app. You don't need the latest status messages your friends are posting hitting your phone when it's in your pocket.
WiFi and. 3G/4G.....if you are in a location that makes your phone drop/search for signal and WiFi is available....use WiFi. The constant searching/seeking and establishing a 3G/4G network connection will kill your battery faster than having a constant 4G connection. This leaves the cellular band free for calls and all your apps that sync/pull data from the internet can happily run over the WiFi connection instead of killing your battery.

I second this, keep your widgest, number of home screens, and social networking apps down. Phones haven't reached the point of being able to be computers quite yet. Here are some apps to keep it snappy though:
Fast Reboot (by Great Bytes Software)- same as a battery pull without having to. Clears up a lot of RAM.
Lte On/Off - with this, you can switch to 3G (CDMA) only, and have it set to automatically default to that setting in the case of you switching to airplane mode for some reason. But it does reset the app if you turn of your phone. Fast Reboot doesn't clash with this app.
App Cache Cleaner - clears out a lot of the cache you otherwise would have to go to Manage Applications to clean out.
That's all I can think of at the moment for non-rooted users. I won't go into rooted b/c this is not the right place. But here are a few battery saving settings:
GPS - have only the Google one on, it's the fastest in my experience.
Display - have it set to the lowest setting when at all possible. Only lowers color distortion in my experience.
Developer optionss - go in here and turn on the force GPU settings. This may not be the case with everyone, but it gives my phone a little more zip and makes things smoother.
Apps (this is the very bottom of the developer settings) - Adjust these to your liking. Perhaps try setting the max number of backgrounded processes to 4.

I wonder how it looks on you ...
on my droid 4 and with Jelly Bean i lost ~5,5% battery by hour no matter what i do even on airplane mode.. still aroud 5% by 1h
please can you advice how its look from your side ?

I had the same thing with my Droid 4. I finally sbf'd it, and reinstalled everything one at a time. This fixed it.

Is there any way for the Droid to use only 2G networks? 3G/4G while idle seems to be the biggest battery drainer.

a battery calibration after rooting device should help.. what it does is delete the fake information from the old/stock ROM and cleans up your battery to new life... better explained here... https://play.google.com/store/apps/details?id=com.nema.batterycalibration...

I have not found that to be the case at all. The battery tools make that claim but it has not helped my battery life (stock or rooted) on any of my multiple droid 4 or d2g

Same here. In a couple cases its just made it worse. I will be trying out the extended battery in a couple weeks though. Hopefully it'll let me go at least a day without charging.

Making it better
The Droid 4 firmware just isn't very battery friendly... and it's not a new phone so your battery probably isn't either. Two things to consider.
LiIon batteries lose capacity over both cycles (cycling losses) and time (calendar losses.) If your battery is 18 months old and was charged nightly, you've lost 25% or more of the life anyhow... much more if the phone was kept plugged in after the charge and ran warm. And the drop accelerates with more cycles. It may be time to change the battery.
Adding JuiceDefender ( I use Ultimate) triples my battery life even in basic mode.
Replacing the battery is really simple; buy one from Amazon, open the back, carefully pry out the old one (it's held down by a double-sided tape), unscrew the connector (very small Torx, but jewelers screwdrivers work), swap and reassemble. $30 later (and a few hours to charge), you have your capacity back.

yeah after trying juice defender for about a month or so i noticed my phones battery life extend much more. so i opted to buy the ultimate juice defender and sure enuff more battery life... i am very pleased with this app. however if in the future i do want to extend the battery a lil more, then i will purchase a brand new battery and then replace the old one...

Turning off auto sync, turning off WiFi while on 4G works. Also make sure there's not any apps running in the background. Being root, there's apps you can download to close any open app

just go into your settings of your networking section:

with CM it is an easy to safe much energy! and if you really want to do this on a right way, you really need to own a rooted system....
1. underclocked my cpu for 200mhz, dont have to comment.... if you use lightweight lounchers and care for background apps, it will noprob
2. use only 2g-networks, those are more available than every other networks, and even tcp/ip works with it, for whatsapp etc it is way enough bandwitch
very important!!!!
3. check your internal recievers after installing an app!! with "autorun manager" on a rooted device you can uncheck every function from every app, even autostart of an already killed facebook app, or statistical functions from apps which comes with most of them
4. get your brightness automated, if it is dark, you can automatically safe energy by a automatically regulation
5. maybe you would prefer to deactivate vibrations/haptic feedback/call vibration completely, its very energy consumpting.....
6. deactivate the gps-reciever complete, and just turn it on if you need it
7. set your display timeout as less than possible for your behaviour, 15 seconds may be enough
8. know what runs in background, evrything in background, sucks energy.....
9. deactivate nfc
10. deactivate bluetooth
with this i get a standby about ~1-3 days! and if im phoning and writing to much maybe not fully to one day. if i watch now on my energy tables, my display is consumpting still 40-60% battery per charge, but i dont think that even more safings would be possible
and with the app "tasker" you can even script this in endless environments

How does JuiceDefender save the battery? I have used many battery saver apps (including Juicedefender) and I always find that they run in the background and kill the apps which I would close anyway. Does it do anything besides kill background apps? By now I've deleted most background apps and have only kept the apps I want (which are few) and I still find battery life subpar.
Also definitely keeping 3G/4G off is a huge help. Wouldn't be able to make it very far without turning those off

I use Autorun Manager pro to freeze Google Play Services. Funnily enough, Play Store and Google Maps still work like a charm yet Google Play Services don't run background
Edited: With stock rom, install SetCPU and change the governor to hotplug. Underclock max frequency down to 800 MHz. You won't notice much different for normal tasks like watching videos, sms,...That setting is enough for me to play FF4 on MyBoy but playing heavy graphic games might not be snappy tho.

For me not using gaaps improve battery life. Every one knows for google play service that you cannot stop Instead I use calldav for my contacts.

me battery drain in me droid 4 jb 4.1.2 with gsm patch is of 60% for screen, the battery only run about 6hs, can i fix this? thanks

[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:
