It is a fluke of the phone. Some say it is because the display uses so little power but I really don't buy that. I think the reporting is not correct.
Try this. Copy your data from your external sd card to you laptop and save it where you can find it. Take your card out and format it on your computer (fat32) if you have an adapter, if no skip to next step.
Insert card back into phone power up and format sd card in the phone. Plug phone into computer and copy the files you moved back onto the card. I found a drastic improvement by formatting my card (but I also changed it)
Make sure you have nothing running that will run your battery down. If the sd card format does not work I would exchange it. After swapping out cards and formatting I got 23 hours out of a charge on normal use (7hours idle while sleeping). I went to bed at 10:30 with 13% and woke up 7 hours later with 6 percent. I can't really ask for more.
Is it really using 75% or is that what is say under the batt stats? Right now 10% of my battery is gone and of that 10% the stats are 48% is cell standby another 48 to phone idle and 4 to the OS. I saw a mention of one of the blur apps that consumes alot of data, you should probably disable it or not use it, not sure the specific name but it was one of the social media things.
75% of battery stats from fresh to dead.
I am not using any of the social networks.

Every Bionic shows up this way for some reason. I don't think anyone has an answer.
My Samsung eats up like 50% in idle ,and the problem is not the SD,i'd formated my SD a few days ago and no improvement

Perhaps I am wrong, but this is how I understand this situation..
The phone tells us the distribution of power drained over uses. It also charts, over time, how much power is being drained. These are very different quantities. That can be seen with a simple example.
Suppose charge my phone while it is off. Once it his 100% battery life, I turn it on and do nothing. Let's assume I don't allow anything to update automatically or work in the background. After 1 minute of not using the phone at all, I check the battery information. More or less "100%" of the battery consumption will have been something like "cell standby" or "idle". All of the power my phone has eaten was eaten by those uses. But, that doesn't mean it ate a lot. To know how much it ate, I look at the top line graph of juice over time. These two things aren't the same.
(1) Am I glaringly wrong? (2) Does that make sense?

To make this more clear for anyone else. If you aren't using your phone for anything, you want "idle" to account for 100% of your use, otherwise you've got some background processes you should deal with.
So your saying that its similar to "System Idle Process" in M$ Windows task manager? That would make sense for the idle phone but what about the cell standby?
I have been wondering about the difference between the two as well. By the name they sound like they could be the same thing really. I mean the phone is standing by is it not idling as well. Or does standby mean processes that are alive in memory? Does this use power? Is this what "standby" describes?
I believe "Cell Standby" is when you phone is searching for towers. Any phone is normally constantly searching and finding towers. If I am wrong please correct me.
The IDLE is the percent of time sitting idle compared to the percent of processes actually being used like the android system processes. Once again correct me if I am wrong.
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 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.

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 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
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 ...

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

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

What I meant was if it was possible to just use 2G for Internet connections, instead of 2G+3G+4G.

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
I did the Towelroot, but my battery usage is absolutely gone to pot.
I checked under battery usage, and it shows a file named "Media" that is using almost 50% of my battery. I can literally see the battery percentage drop 10% in 1 hour - with no usage. I can actually see it dropping before my eyes. Otherwise, the other functions are working great.
I installed Titanium Pro to freeze some bloatware, and at the bottom, I can see two files that are greyed out with lines through them. "Media" is one of them. The other is imsqmisocket. I didn't delete these or freeze them, but they appear to be removed from my system. When I click on them in Titanium Pro; I have no option to restore, or undelete. The imsqmisocket doesn't seem to be listed at all under battery usage.
Any ideas about what "Media" is, how it may have been deleted / frozen, and why it's drawing so much battery usage? I haven't been using ANY media type functions, but it's gobbling up my battery.
The rest of the battery usage seems normal for other applications / usage.
Thanks for any help.
Edited to reflect: In all fairness; the battery issue existed before the root. I'm just trying to resurrect this $700.00 paperweight. I just didn't think it was that bad!
have you loaded any app that can provide wakelock info? that's the best way to identify what app it is.
Wasn't there a problem in the Samsung tab 2 under stock that when the external SD card got corrupted it constantly attempted to scan the card for media consequently destroying the card and killing the battery? Maybe that's what is going on here
