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.

Hey guys --
I did a search and while there is much discussion of deep sleep problems, there is no clear way I could easily find to identify the cause.
I have CM7.20, the MiRaGe latest build on my NC, with the settings listed in my thread (see the sig). Recently I noticed that it is not entering into deep sleep, indicated by losing ~20% battery while it is asleep overnight in about 8 hrs. Battery results tell me it's "WiFi" taking like 30% of the battery, which seems quite odd, since I had it set to turn off WiFi while the screen off unless connected to the charger.
Any clues on how to identify the problem with deep sleep?
As for usage, I am using my NC 99% of the time with the following apps:
Moon+ Reader (probably 70% of time)
YouVersion Bible app (most of the rest of the time)
Dolphin Browser HD (maybe 2% of the time)
Enhanced Email and MailDroid - very occasionally but they are checking mail on 15 min intervals when wifi is on.
I have a ton of other apps installed but I almost never use them except for these.
Any help on how to determine what is causing the NC to not go into deep sleep will be immensely helpful. I have a 2-week Euro business trip coming up next month and I would really like to solve this before then.
Thanks!
Better Battery Stats might help. Try turning off sync before bed and see if you still lose 20%. If so, it's definitely some app that's the culprit. Grab something that will tell you what program is using data and how much/how often and you should be able to isolate it pretty quick.

OK, but it should be turning off wifi, and therefore sync for ALL apps, when it is asleep. Can an app override this setting? That's my guess, is some app is doing this. How can I ID that?

Like envygreen said use that app to track wakelocks. Even if wifi is off, some app may be applying a wakelock to try to sync.

Alright, I'm on it
So last night I finished charging it and read for a couple of minutes, then put it to sleep to see how it went overnight.
My Wi-Fi sleep policy is set to turn off wifi when the display is off.
When I got up this morning I checked it and it had lost over 10% battery over night, and I checked BetterBatteryStats and I think it is going into deep sleep but maybe not shutting off wifi.
I have attached the screenshots from BetterBatteryStats, and I think I need help interpreting them and finding the cause.
ok, so here I am replying to my own thread... If I am reading this right it seems to be looking like my wifi is on the entire time, not only when the screen is on. Is this the right way to read this? In this case, it looks like "Wi-Fi sleep policy" being set to "When screen turns off" is not actually working... right?

It sure looks that way to me too. It says wifi on 8 hours. Did you try toggling the setting a few times? Also you are on Mirage and he may have done something in his tinkering that messed that setting up.

yeah I did toggle the setting on and off, and in fact before I had it set to "On during sleep if plugged" for a long time, recently changed it, thinking maybe this was the cause.
But it does appear that maybe this is what is killing the battery. There doesn't appear to be any network activity when the screen is off, just looks like the wifi radio is powered up.
Any advice?

Hmm. that seems like an extreme step, but maybe ... wonder how much of the snappiness I will lose.
EDIT: OK I switched to CM7.2 stable. Nice I didn't seem to lose any settings. Let's see how it goes. Thanks for the advice, I'll report back here if it still does the same thing.
Also uninstalled beautiful widgets... figured maybe that could be causing an issue.
Oh, and I probably had a SOD kernel patch applied... perhaps that was the problem too
guess I should change only one variable at a time for a good test, but in reality I just want to get it fixed and not really diagnose it.
I was having a similar problem...what I did was run the V6 supercharger script, granted i am running CM9 atm but it took care of any problems I had with battery life and wifi signal.
Question: does having WiFi on keep the phone from going into deep sleep at all?
I have found that my phone is not going into deep sleep. I checked what is holding wake locks, and the time with wake locks is way less than the time the phone has the screen off, so it appears it is not deep sleeping, even though there are not wake locks.
I have an extended battery, so I get good battery life, but always interested in improving it. But I also have this thought that if I have to turn everything off, and only synch when I turn the screen on, that is not ideal either.

Get CpuSpy free on play store. It will tell you exactly how much deep sleep you are getting.
Having wifi on all the time should not prevent deep sleep. Only when things use it does it come out of deep sleep.

I have CPUSpy Free, and that is how I know I am not getting deep sleep. My challenge now is to identify why.
OK, so it seems that CM7.20 stable definitely fixes things. I didn't flash the SOD fix, so maybe the SOD fix was preventing deep sleep before, or maybe something else in the kang build was preventing deep sleep with wifi on when the screen is on.
However the better battery stats still seems to say my wifi is never actually going off. I am not sure I am interpreting the results correctly. It looks like the wifi is on all the time even though it's set to turn off when the screen is off. But I can let the NC sit on my night stand overnight and lose only a couple of % where it was like 10+% before. I still think my problem was due to some app that updated and not the ROM because the problem started weeks after I last updated the ROM.
Hi Guys. I posted this in other forum, and been an XDA member I thought, why not posting this here also, although I know that what I'm posting here most of you have already discovered or worked with it, but just in case you haven't or maybe it can help other newbie member looking for an answer.
So here it's just as I posted it in the other forum (Sorry for those of you that have read it over there).
Some of you won't even read this thread completely, some others maybe interested to know what I've done in the past couple of weeks to have the great battery life I'm getting right now, for the past couple of days, after I finished making all the adjustments I'm getting 6.50 - 7+ hours of screen time, twice as much as I was getting with my S4, 1.25+ more than I was getting during the days I used the M8 (no longer with me), so for those of you interested I decided to give you some hints and explained in details what I've done. Please remember that this is solely based on my needs and phone usage, so you do the adjustments that you think can fit your needs and leave the others as default.
Brightness and Display - I adapted myself since my S2 to use low brightness, I can say that about 20%, I only use the Auto option when I need it, but most of the time been at Home or at the office I don't need the brightness too high. I'm using Adapt Display after 1 year using Normal Mode in my S4, just for trying, so far it's good this way for me. My Screen Timeout is 1 minute, But if you don't need it on that long just leave it as default.

}
Bloatware - From the Samsung Apps I just left on of S Health, Smart Remote, Calendar and Memo, before disabling S-Voice (Just in case) I disabled the Home Key Activation, then I installed the Gear manager to be able to use my Gear 2 Neo. From Google I disabled Google Play Music (It has been in the past a Battery killer, maybe is better now but I have no use for it on this phone as I have all my music on my SD card) and Google Books, but installed a lot of other Google apps (I think the rest of them, jaja). I also disabled Polaris Office as I have other Office Suites purchased. And all the T-Mobile stuff. (All of these I've noticed that run on the background draining your battery)
WiFi - I turned off the Smart Network Switch, because when I'm at home or in the office, connected to my wifi, I move around a lot and I stay at wifi range edges a lot, so this feature can be switching on and off constantly and it will cause battery drain. then I turned off Network Identification as I don't need this, and one thing I have learned, at least in my case is that leaving the Wifi on all the time drains the battery a lot, so I changed the "Keep Wi-Fi on during Sleep" option to Only when Plugged in. I'm at T-Mobile, so I have the wifi calling feature, it's great but I leave it off until I need it.
TouchWiz features - I love TouchWiz, for me all the others Android Skins are plain and boring, so I use a lot most of it's features, but I just turn them on only when needed, there's a reason why we have those Toggles there, so I edit them and rearrange them in the order I want so I have it available when I need them. The only options I leave on all the time are the Motions and Gestures and Air View, because I use them all the time.
Location - Just like I mentioned above, I just turn this on when needed, and even then just select if you can use the Power Saver mode. Also, I don't need Location reporting, but I do use the Location history for my Google Now and other Google Apps.
Google Now - Be sure the Location settings are in order with the above and I disabled the "OK Google" default feature as by it's nature, this is all the time on and "listening" waiting for the command.
Ultra Power Saving Mode - Great feature that I turn on every night while I sleep, in 7+ hours activated it has used only 1 % of battery.
Developer Options - Well this is something that I don't know exactly how it affected but for me it did something, let me explain, I decided to give it a try to the ART option on the Runtime System, I heard that for some it helped with the battery and performance so I did it, well it took a long time after it rebooted, and it took almost 1GB of my System memory just by doing this change, but I tried it for a day, after I saw that I didn't see any difference I could notice other than most available ROM, with Dalvik it was always using 1.40-1.5 of the 1.81 GB, with ART it went down to 1.1 and after 1 reboot I saw going to 1GB, so I like that, but, I began having the No-Response power button that some people have reported when trying to wake up the device I decided that I was going back, well, in a summary, it went back to Dalvik a lot quicker, I got my 1GB of Memory back, and for my surprise the ROM usage is lower than before, when I got the phone and until I did this, it was never lower than 1.4GB, but now after switching back I'm getting 1.2 most of the time. So I'm guessing that switching to the other one and back cleared some other stuff that was there by default. Why I'm letting you know this, well, immediately after I switched back to Dalvik I began noticing better battery life (I'm talking since Friday), it may be just a coincidence maybe not, but it won't hurt trying it if you don't find any other solution.
Well, that's all I can remember for now, if I remember something else I will post it as a follow-up, so I hope that this can be of some help to some of you new to Android and maybe some of you that are not new to Android but new to Samsung Galaxy line and are a little lost on how to have a better battery life.
For now, here it's my last Battery Stats, before I re-charged yesterday morning, I'm still at that Full Charge now, In full use now that I'm back at work and my Car Bluetooth connection and my Gear 2 Neo, so this afternoon I will have a better idea, but as of now I still have 33% battery left after 22hrs 48 mins on battery and 4h 38m Screen On time, so it seems to be going strong for 7 hrs of screen on time.
Google Now
Which of the location settings do I need on for Google now to still work? I wanna try to keep all the google now functionality enabled. I had pretty bad battery life my first full day with the phone. (I cant post imgur links since I'm new here). but basically my "Awake" bar on the battery history was solid blue all day. Phone died after about 13 hours of being on and 2 hours of screen time. Android OS and Android System took up the majority of my battery. The phone was awake the entire day and I couldnt figure out why. I turned off the wifi settings as you mentioned above and disabled as much of the samsung crap as I could find. I do leave location on all the time, but on "Power Saving" mode, not sure if thats making a huge difference.
Any input is appreciated.
Looks fine but I get 7 hours of screen time on auto brightness but set to a couple of notches below Centre. And screen mode on pro, for natural colours. The other things seem logical, though ultra power saving mode for night time seems a bit extreme. I have it on normal and it uses about 4 per cent overnight.

Ultra Power Saving Mode while I sleep doesn't hurt anything, anyway, I won't be using the phone all night, once I wake up I turn it off immediately and everything goes back to normal, so no harm.

Great, thanks a lot. I am gonna try these settings and see how it goes. I was a little disappointed before, but hopefully these can right that. I do like the location history, but not if its drains my battery like that.
S5 doesn't consume much battery at night, between 1 and 3% percent max as i have noticed without Ultra Power Mode.
You gave good tips for optimisation to those who haven't done that yet.
I suggest people to install Juice Defender as it will disable data and renable it only when screen is on or every xx minutes it's off (it makes a big difference on LTE networks now).

I get what you mean, but my case was more like 4-5% lost overnight, so losing just 1 with ultra power saving mode saves me 3 to 4% that I can use later on the day for about 15 more minutes of screen on time, and again, I'm not using the phone while sleeping so I don't see the need for not using the Ultra Power Saving Mode.
Follow up, I just arrived at home and even when I didn't get the 7 screen on time that I thought I'd have, I ended with 6 hours. My phone usage while working is very different than when I'm at home, plus connected receiving emails by the dozens, using Calendar, memo and other working stuff, plus the Mobile signal is at the borderline of bad, and it switches a lot from LTE to 4G and vice versa so getting 6 hours of screen time on over 30 hours on battery after a full day of work where my S4 was giving me not even 4 hours is really great and it keeps amazing me.
Thank you!
So far today I'm at 1 hour of screen time, my awake bar is now only solid when the screen is on and I'm at 87% battery with the phone unplugged for 3 hours. Finally Android OS and Android System are much lower, thanks a lot!!!! I just changed the wifi advanced settings and the location settings.
Sir.
Im having the non-responsive power button issue. ot took me a lot of uninstalling to some apps(greenify and gravity screen) now using gravity with no problem. dont want to test greenify though. but that problem was really a big issue. I couldnt even make the power button work.
Do you know if this is some kind of software issue or hardware problem?

I think its great and all, but honestly.. except for bloatware, I have everything on. Google now included. GPS ALWAYS on. brightness to max. the fact is, our phones come packed with great features and I bought it for most of them, I don't want to lose them to get some extra battery life.. and you know why? Because with everything still on I get over a day easily with heavy use still. Back in the day with my EVO, sure I wanted some battery saving tips because I couldn't make it a day. If I forget to charge my phone now, I'll wake up and still have close to 30% left, a quick ride to work charging it and boom, back to over 50% and that'll be just fine even with heavy use.
After all that said, we have removable batteries for a reason! and nothing beats having an extra one just in case.
Anyway, my opinion but I guess this whole battery squeezing more tips is like the Prius's drivers coasting to stop signs and red lights from a mile away to save an extra 2mpg

lucky you, i go to sleep at 100% and wake up with 66%. Since im not rooted i cannot view wakelog stats. All i know is the biggest battery drainer is "Android System"

Hey I figured I shared my experience here since I also had a massive battery drained from android system. I am rooted but u can still try this to attempt to stop the darn android system. here is what worked for me. I charged my phone 100% then I left my phone on full power save mode. Here is what I found out....my android system wouldn't go below 26%....after 6 hrs of full sleep now is at 18% and im not getting any wakelocks....ill post my screen shots...

Hi Guys. I posted this in other forum, and been an XDA member I thought, why not posting this here also, although I know that what I'm posting here most of you have already discovered or worked with it, but just in case you haven't or maybe it can help other newbie member looking for an answer.
So here it's just as I posted it in the other forum (Sorry for those of you that have read it over there).
Some of you won't even read this thread completely, some others maybe interested to know what I've done in the past couple of weeks to have the great battery life I'm getting right now, for the past couple of days, after I finished making all the adjustments I'm getting 6.50 - 7+ hours of screen time, twice as much as I was getting with my S4, 1.25+ more than I was getting during the days I used the M8 (no longer with me), so for those of you interested I decided to give you some hints and explained in details what I've done. Please remember that this is solely based on my needs and phone usage, so you do the adjustments that you think can fit your needs and leave the others as default.
Brightness and Display - I adapted myself since my S2 to use low brightness, I can say that about 20%, I only use the Auto option when I need it, but most of the time been at Home or at the office I don't need the brightness too high. I'm using Adapt Display after 1 year using Normal Mode in my S4, just for trying, so far it's good this way for me. My Screen Timeout is 1 minute, But if you don't need it on that long just leave it as default.
Bloatware - From the Samsung Apps I just left on of S Health, Smart Remote, Calendar and Memo, before disabling S-Voice (Just in case) I disabled the Home Key Activation, then I installed the Gear manager to be able to use my Gear 2 Neo. From Google I disabled Google Play Music (It has been in the past a Battery killer, maybe is better now but I have no use for it on this phone as I have all my music on my SD card) and Google Books, but installed a lot of other Google apps (I think the rest of them, jaja). I also disabled Polaris Office as I have other Office Suites purchased. And all the T-Mobile stuff. (All of these I've noticed that run on the background draining your battery)
WiFi - I turned off the Smart Network Switch, because when I'm at home or in the office, connected to my wifi, I move around a lot and I stay at wifi range edges a lot, so this feature can be switching on and off constantly and it will cause battery drain. then I turned off Network Identification as I don't need this, and one thing I have learned, at least in my case is that leaving the Wifi on all the time drains the battery a lot, so I changed the "Keep Wi-Fi on during Sleep" option to Only when Plugged in. I'm at T-Mobile, so I have the wifi calling feature, it's great but I leave it off until I need it.
TouchWiz features - I love TouchWiz, for me all the others Android Skins are plain and boring, so I use a lot most of it's features, but I just turn them on only when needed, there's a reason why we have those Toggles there, so I edit them and rearrange them in the order I want so I have it available when I need them. The only options I leave on all the time are the Motions and Gestures and Air View, because I use them all the time.
Location - Just like I mentioned above, I just turn this on when needed, and even then just select if you can use the Power Saver mode. Also, I don't need Location reporting, but I do use the Location history for my Google Now and other Google Apps.
Google Now - Be sure the Location settings are in order with the above and I disabled the "OK Google" default feature as by it's nature, this is all the time on and "listening" waiting for the command.
Ultra Power Saving Mode - Great feature that I turn on every night while I sleep, in 7+ hours activated it has used only 1 % of battery.
Developer Options - Well this is something that I don't know exactly how it affected but for me it did something, let me explain, I decided to give it a try to the ART option on the Runtime System, I heard that for some it helped with the battery and performance so I did it, well it took a long time after it rebooted, and it took almost 1GB of my System memory just by doing this change, but I tried it for a day, after I saw that I didn't see any difference I could notice other than most available ROM, with Dalvik it was always using 1.40-1.5 of the 1.81 GB, with ART it went down to 1.1 and after 1 reboot I saw going to 1GB, so I like that, but, I began having the No-Response power button that some people have reported when trying to wake up the device I decided that I was going back, well, in a summary, it went back to Dalvik a lot quicker, I got my 1GB of Memory back, and for my surprise the ROM usage is lower than before, when I got the phone and until I did this, it was never lower than 1.4GB, but now after switching back I'm getting 1.2 most of the time. So I'm guessing that switching to the other one and back cleared some other stuff that was there by default. Why I'm letting you know this, well, immediately after I switched back to Dalvik I began noticing better battery life (I'm talking since Friday), it may be just a coincidence maybe not, but it won't hurt trying it if you don't find any other solution.
Well, that's all I can remember for now, if I remember something else I will post it as a follow-up, so I hope that this can be of some help to some of you new to Android and maybe some of you that are not new to Android but new to Samsung Galaxy line and are a little lost on how to have a better battery life.
For now, here it's my last Battery Stats, before I re-charged yesterday morning, I'm still at that Full Charge now, In full use now that I'm back at work and my Car Bluetooth connection and my Gear 2 Neo, so this afternoon I will have a better idea, but as of now I still have 33% battery left after 22hrs 48 mins on battery and 4h 38m Screen On time, so it seems to be going strong for 7 hrs of screen on time.

I have found that on mine too, and controlling which apps were using location & how frequently helped a lot. Life360 was my worst offender by far. If I toggle off location the usage flat lines and Screen stays as top power user.
I have ended up uninstalling life360 and leaving location on.

Anyone know why my TF701T completely loses all its charge, even when fully charged up, when i close the tablet with keyboard still attached?
I can fully charge it, tap the sleep button top left, close the keyboard, and then less than a day later it has lost all charge and then needs to be fully charged up again.
This is getting really frustrating, otherwise its a great tablet.
Android version 4.4.2
Thanks.
Have you tried a reset and see if the problem still exists without any apps on your tablet? I may be a problem with an app draining the battery.
Just started happening to me too

This just started happening to me a couple days ago. I take my tablet to work, it stays in my backpack powered on but not being used. Most days I get home and it's either still at 100% or at least in the high 90s. Two days ago when I got home it was at 18% and yesterday it was 15%. I'm beginning to suspect some app update is killing it. I haven't changed anything else. I don't have a keyboard. Running the latest CromiX 7.03.
This has been happening for at least 6 months, maybe longer.
Haven't tried a full factory reset and reinstall of apps - I was hoping it might be simpler than that.
No other android devices I have excessively drain the battery (Note2 phone, Nexus 7 tablet) - why should this tablet be different?
Have a battery monitor installed for about 2 weeks and no apps stand out having excessive wake locks. (apart from the battery monitor itself, which is to be expected )
Did you use Netflix?
There is a bug with Netflix that it completely drains the battery on the Tablet after it runs. The workaround I use is to reboot the tablet after I am done with Netflix

This has happened to me since I upgraded to 4.4.2. Since I had only just purchased the TF701T it had very few apps on it and I was able to observe some things via teh power and battery stats;
1. When stored in a bag the battery discharged throughout the day going from 100% to 20% in just over 8 hours
2. The TF701T had woken up every 5 - 10 minutes even when i thought it wasn't meant to
3. Wifi appeared to stay on when it was woken up as it used the most power
4. Google Play Services and Android OS initaited most of the wake ups (approx 70%)
I turned off Google sync and also now turn off Wifi manually when I finish a session. Now I am losing almost zero battery whilst in standby i.e. On with lid closed.
It was the same for me. The battery turned of in 8h without use. I tried to wipe and restore without result.
I re-calibre the battery with the app BatteryRepair. Now my tablet is 50% after 24h unplugged and 3h of use.
Hope it works great for you too.

Ok, quick update;
i wiped the tablet using the Asus tool, which removed all my apps and gave me a clean base to test from.
I noted that there was now no battery drain at this level, with google sync on and wifi on.
I then slowly added the apps i needed (probably over half of them I didn't need - this is always a good time to consolidate)
I then started noticing the keyboard battery was draining even while closed, but not as much as before.
Reading your above posts, i turned off sync, kept on wifi. I still noted a bit of drain.
I then just turned off wifi before closing (left sync on). No drain.
Also i noted, the mouse(pad) always now returns when i open the tablet from sleep.
So for now, i can conclude that the combination of;
having the new Oct 18 patch,
reinitialising the tablet, then reinstalling (& reducing) my apps,
and turning off wifi before closing/sleeping the tablet seems to have stopped the battery drain.
for now
ps. no, i dont use Netflix.
another update:
fully charged the tablet last night to 100%, turned off wifi, then closed the lid.
Opened the next day (10 hours later), charge still 100% on both tablet and keyboard.
Definitely looks like its the wifi, and turning it off before closing stops the drain.

That is what does it for me too.
Only this helped me
I found nvavp is used by NVIDIA's Widevine DRM proprietary plugins.
I removed all proprietary DRM plugins from /system/vendor/lib.
Code:
/system/vendor/lib/drm
/system/vendor/lib/mediadrm
/system/vendor/lib/libWVStreamControlAPI_L1.so
/system/vendor/lib/libwvdrm_L1.so
/system/vendor/lib/libwvm.so
Then, the idle battary life becomes normal.

Works for 5 hours already.
My Tablet lasts 2 days before its totally dead with ZERO USE!
Updated to 5.0.2 as i hoped this would fix it. No change
Lost 10% battery while in power saver mode in a few hours!
Lags all over the place when scrolling, the play store is horrible when scrolling apps.
Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?
Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.
clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.
I flashed a whole new OS... should i wipe it?
You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.
John.
Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.
So i wiped and its still 48 hour batter!
Battery %bleed
Losing around 30% battery over night idle.
*wifi & sync on...

Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.
Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.
How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.
John.
disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.
Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day
Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.
i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?
