Battery dying very quickly - what to do?

My Evo battery is draining at a rate that is all together too fast. I took it off the charger about 3.5 hours ago and it has drained about 30-40%. I have not made a call nor used the net at all save for the receipt of 3-4 emails. I had a rooted phone but I reset the phone back to complete unrooted stock. I have not even so much as installed an app. What can I do about this?

turn off your mobile data when not in use. This will save tremendous amounts of battery.

if you search the forums you should find countless threads on battery and how to find out what is draining your battery and to extend life.
not sure why you would unroot unless you were exchanging it at sprint store but it greatly limits what you can do to help prevent battery drain. If you dont want to mess with much jsut use a rooted stock rom and it is pretty much the same thing as being unrooted but you keep the extra rooted benefits.
your best bet on non rooted device make sure mobile data, 4g, auto orientation, bluetooth etc are turned off. do the HTC battery condition/charge trick. and turn off background sync.
my suggestion is to re root and look into undervolted kernels and many other battery saving tricks found using search!
hopefully it helps some.

I had the same problem OP.
Turns out my radios weren't update.
Head over to the developer section and download the newest radios and stuff.

I've seen significant improvement of my battery life by using Collin_ph Battery Tweak 1 that was offered by Myn's when I flashed his/her's rom. I had my BF take his Evo to work after he come home complaining that the charge would only last about an hour or two and behold, he got through the whole day without having to charge his battery. This is after listening to music at work for 8 hours also. I HIGHLY recommend this tweak for ROOTED PHONES as I and everyone else I've recommended loves their Evo now and have no complaints...I'm at work right now and I'm at 79% and when I usually get home the battery is either still green (full) or orange (med) charge. I'm not sure if this tweak can be used with other mods but I'm very happy with this tweak as it has made my phone perfect now~~

Could be a Rogue app running killing your battery or radios not updated like stated above.

I recently started having the same issue. Advice such as turning of data and the GPS aren't helpful since the device functioned fine with GPS and data on before. Also if the battery was draining at a slower rate on the current radio before, you shouldn't need to update it, should you?
Seems that either something is making the Evo use more juice than it was before or that the battery is not holding the same capacity it used to. For some reason Phone Idle and Cell Standby have been using quite a bit more juice than they used to.
I don't like some of the software mentioned to try and locate anything that could be using more juice since those programs seem to use quite a bit themselves. Either way, what could be doing it that would come up as Phone Idle or Cell Standby in the included battery monitor? Wouldn't anything else come up under Android System?
The battery draining that quickly is not normal even with background sync, GPS (idle), 4g, data, or anything else on. There is another issue which must be solved. To troubleshoot so far I've tried another battery (same thing happens) and now I'm trying with everything turned off. If I can isolate what was causing my sudden rapid battery drain, I'll update everyone. This just started a couple nights ago for me. I think I'm on the latest radio, but I'll check.

Last post sums up my problem perfectly. I have an extended battery that lasts half the time it has over the last 4 months. Started with the radio updates. running myk

Use the battery usage functions of 'spareparts' to determine what's consuming cpu or preventing the phone from sleeping.
Can't fix the problem until you've isolated what's at fault.
Turning off mobile data will indeed fix a problem of some app trying to access the network, but it won't solve the actual cause.

I think juice defender does this automatically when the screen is off.

In the case of my phone, and I believe the OP's, we don't have any rogue apps or things running in the background. I know this phone like the back of my hand. I have completely uninstalled unnecessary apps like facebook, twitter, all things like news and weather are on manual update, i don't keep 4g or gps on, and I use wifi at home. I turn off 3g in terrible reception areas. I'm not a new user who doesn't understand the basic ways to save a little battery. I'm pretty sure the OP isn't either by his post. I use my phone the same every day. My chinese extended battery would last me easily from morning to bedtime with 20 to 30 percent to spare. Now I can't get near that after the radio updates. Since it's been well known that something is weird with these current updates, I've downgraded to 1.77 to see if that helps. My phone was sleeping fine though, so I don't know how much it will help. Always some BS with this phone.

Log out of gtalk and latitude. Those two seem to kill battery.

I appreciate it. I really do. But that is exactly the things I'm saying are already off. GTalk is turned off immediately on my phone from the jump and latitude has never been opened. It's got to be radios. I guess I'm not really asking a question, I'm just telling the OP he isn't alone.

this is the thread with flashable .zips of alllll the radio updates ever out for the EVO.
http://forum.xda-developers.com/showthread.php?t=715485&highlight=radio
if you are having trouble after a radio update, just try some of these other radios and see if that helps

Your best bet would be to root your phone again and give one of the SBC kernels a shot. I'm running CM 6.1.2 along with Zendroid 1.1.0 BFS AVS SBC and I can easily get 16+ hours with HEAVY use. And when I say heavy use, I mean hundreds of sms, dozens of calls and lots of websurfing. You will love the SBC kernels. Give it a try.
PS. My name is HondaCop and I approve this message.

We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

That sounds like a very weak cellular signal is forcing the radio to keep searching for it, draining the battery very quickly.
One way to somewhat alleviate this problem is to force roaming, to connect to a provider with a better signal.
"Roam Control" app does this (Market).

My battery advice to those who need battery help

I keep reading on here about how either someones battery life is either awesome or great or this or that. It seems that many folks on here with great battery life are old pros at milking their phones for the best battery life possible, while others may not know the best methods for getting the optimal battery life they want.
So here are some tips for getting the battery life you want:
1) Calibrate your battery by letting if completely discharge and then charge it using the wall charger it came with. Do this at least three times so the phone has a chance to get real statistics.
Update: It is recommended that you do not do this very often as some say it could damage the battery in the long term. You should do this early on in the life of the phone as the damage if any would be minimal. This needs to be done regardless. It is the only way for the phone to get an accurate full/zero reading.
Update 2: I have found that after doing a factory reset, you need to do this step again. After a factory reset on 4.1.83 (most recent update), my battery life dropped considerably. After letting it discharge fully and then charging it with the phone off again, I was back to normal battery use.
2) Set wifi to sleep when the phone is not in use. Unless you are streaming data such as pandora or other data intensive programs with the screen off, you do not need it on (I will talk about background data in a moment for those who are going to mention that the phone still does data while it is sleeping). You can change the setting by going to Settings > Wireless networks > wifi settings > menu button > advanced > wifi sleep policy
ofek said:
You should write that after settings it you need to click on menu button->save.
If you will not do this step, every reboot it will restored to "Never" option.

3) Disable motoblur's account settings sync over cell data. This setting causes all of your account information to sync over your data connection when wifi is not available. This should be disabled as it will constantly sync and drain your battery even when the screen is off. Really do you need you facebook contacts that are synced to your contacts to be updated every five minutes? Settings > Data manager > Data Delivery > social apps > sync over wifi.
Update: Only disable the Social Apps that sync over background, do not disable the Background data. Disabling background data will cause certain things to not work properly, like for instance the gmail app.
Update 2: If you are using the Twitter/facebook/whatever apps (real apps) you should go ahead and remove the associated accounts from Motoblur. You do not need them to sync twice as motoblur will sync them with it's account and then the apps will sync. The downside to this though is that any contact pictures you have synced from those accounts will no longer show up in contacts forcing you to manually add pictures to your contacts.
4) remove widgets. Widgets drain batteries when they are active. Most of them are useless and really serve no purpose other than to try and make you feel important about yourself. I mean really, how useful is a facebook widget that only shows one or two peoples updates? Trash the ones you can live without. If you are using a launcher other than motoblur, go and load motoblur and make certain there are none running on that launcher as those are still active even if you use another launcher.
5) live wallpapers suck battery like crazy. While they are nice eye candy to view, they are not worth the drain they cause. Even when you are in a app, just like the widgets, they are draining your battery.
Update: Some live wallpapers are better on battery drain than others, but they still drain battery either way. I will not use a live wallpaper as it serves no purpose other than eye candy, and eye candy on a phone I can live without.
6) Task killers. Yeah not going to touch this one as everyone who reads these forums should know better by now.
7) check individual programs as you install them and make certain they do not autoupdate content. Pulse news reader is a good example of a program that pulls data in the background even when you haven't used it in weeks. Really is it going to kill you to hit refresh when you load it?
Update: If you are using the AT&T program "Mark the Spot", it constantly is checking device performance and is constantly checking your location for it to "work". Be sure to watch this app as it drains a lot of battery through out the day.
8) turn off bluetooth, gps, and wifi when you are not actively using them. Wifi when on is always scanning the area for networks, bluetooth is always actively broadcasting (on some phones) and who needs gps when you aren't on the move.
Update: If you are experiencing a switch from H+ to Edge frequently such as in your home where you have wifi running and do not have a AT&T cell device, then turn off your data connection. Your phone is constantly trying to connect to the H+ network when it isn't already connected and draining power. If you are on WiFi, then your data connection is not needed.
I have heard Tasker is great for setting up an automatic script on your phone to do it for you so you don't have to think about it, but remember that all extra programs including tasker eat away at your battery and without real world testing, I can not promise you will see an improvement or a loss in battery.
You can also use APNDroid to do it manually if you would rather have full controll of your data connection.
9) Quit watching porn on your phone. Use your computer for that. Ok maybe I am the only one who does this but I doubt it. Alot if the free poem sites use flash videos and the more you use flash the faster your battery drains.
Update: Yes I know this is hard (no pun intended) for some of you to do, but the idea is sound. Using flash videos (the bulk (again no pun intended) of porn videos use flash).
These are not the only ways to have a great battery and this information may not be useful to you, but I can go nearly 20 hours of moderate to heavy phone use and still have anywhere from 40 to 60 percent battery left at the end of the day.
If anyone has any other advice that they feel should be listed here, please let me know and I will gladly add it to the mix.
Good luck folks.
Addition (5/12/11)
10) For those of you with the .83 update, please keep in mind that the update now forces you onto the EDGE (2G) Network if it can receive a better signal/stable connection. If you notice you are on EDGE more often than the H+ network, then disable your data connection. What is happening is that even though you have a solid connection to the EDGE network, your phone is constantly seeking the H+/3G networks thus using much more battery life than before. If you are at home or somewhere where your phone can connect to a wifi network, consider turning off the Data network. You should also disable your data connection whenever you are in a No Signal area. Again the same problem happens when you have no signal.

Advice from other Members:
From Deggy
I would like to add to the OP's list of things to do to improve battery life:
Turn off date when not in use for a long period of time like work or school. Settings -> Date manager -> Date delivery -> uncheck Backround data and Data enabled. Don't worry, you'll still get your texts and phone calls.
The Market is a big drainer. Market -> hit menu -> settings -> change notify me -> do not notify me.
Those two are the big ones to worry about IMO.
The other tips are either cliche stuff or other people said already. Wifi off, GPS off, brightness down to 0-20%, ect. Auto sync is killer.
I unplug my phone at 9AM and come home from work at 9PM and my phone says 75% with moderate use (Circle battery widget uses 1% increments). 3-4 phone calls. A LOT of texting (wifey likes text me). Internet during 30 minute lunch. Play Words with Friends a good amount.
I don't use live wallpaper but I do use a darker colored static one. Only got 4-5 widgets on my screen. 3 home screens. Using Launcher Pro.

In some of the other battery threads, ppl have been commenting on how they've had success in extending the battery life after a hard factory reset. What that basically does is it deletes and regenerates the batterystats.bin file in /data/system and if the battery was essentially mis-calibrated prior to the reset, the reset fixes it thus giving better measurements. ie. perhaps after 10hrs of usage the phone might say u have 5% left, but in reality you could have 40% left.. the regeneratin of batterystats.bin would recalculate that correctly
if you want the benefits of having that reset process but rather not go through having to restore all ur apps/back them up.. u could always manually go and delete the batterystats.bin file (only if you're rooted). i would recommend deleting the file after fully charging the phone overnight then unplug it so that it generates the file again. if you'd prefer an app to do this for you automatically you could always go to the marketplace and get 'battery calibration' app for free and it does the same thing

The following was posted on the MotoAtrix forums on Motorola's website. https://supportforums.motorola.com/thread/51776
I've seen a lot of posts in a lot of threads about how to save battery life on the Atrix. So, I figured I'd start a consolidated thread on the matter. These are the tips 'n tricks I've used, and I can get 2 days of battery life on the Atrix now.
1. When I first got the Atrix, before turning it on, I charged it for 4 hours. After turning it on, I let it run until it died, then re-charged for 8 hours. I did that for a full week. They say that this isn't needed with the new-fangled batteries, but I have always done this, and have always gotten great results.
2. Live wallpapers are not your friend, especially in two circumstances: 1. you use your phone a lot, and 2. you use the stock unlock screen where everytime the phone wakes the live wallpaper is playing. Granted, they don't eat up much battery, but if you're looking to get every ounce/percentage out of your phone, it's a luxury you can leave at home.
3. Did you install a new launcher? If so, did you clear out BLUR? I had my BLUR interface up and running with widgets and shortcuts, etc, etc. When I switched to ADW I noticed an increase in battery drain. I re-loaded BLUR and deleted all apps, widgets, etc so BLUR is blank. I now have great battery life with ADW running.
4. Widgets - ugh. They're pretty, they're big, they're animated, and they eat battery like bees eat pollen. Be mindful of them, and be willing to accept the consequences of the "cool factor".
5. Screen timeout. Yes, it's annoying to unlock your phone every 5 minutes, but you do save battery life with a 1-minute or less timeout option set.
6. Close your apps! Many apps, games especially, are fantastic at running in the background on Android, but they're sucking battery. They all restore to your previous position quite well, so if you're done for a few hours, exit it instead of just going back to your launcher screen.
7. "back" vs. "home" - the back button (the reverse arrow) does a much better job of closing down programs than the home button which just brings up your home screen, leaving whatever you were doing to hungrily consume battery like zombies on a corpse.
8. "manage apps" is your friend - go to your app tray, hit the menu button, and select "manage apps" - you can see all the running apps and kill them selectively. Some, like Facebook, Skype, and others, will stay there as long as the phone is on once you use it, unless you kill it. Be forwarned though, you'll stop getting notifications if you do this - another informed tradeoff. I do this once every few days, or if the Atrix seems sluggish.
9. Screen brightness - the "auto" setting doesn't work all that well, but I highly recommend leaving it there, and/or using a screen brightness toggle widget on your home screen to manage this carefully. Screen brightness on maximum will yield the best viewing experience but it does drain battery the fastest of all.
10. Choose your BLUR accounts wisely - like widgets, if you have LinkedIn and Facebook connected through BLUR, it will run ALL THE TIME. Using the native apps from the market will definitely decrease your overall drain and give you better control over when and how your battery is consumed by those services.
11. Auto-kill or be killed - A good rule of thumb for me is to only auto-end a task if you know exactly what it is, and it didn't come with the phone. Chances are if you don't recognize it, even if it looks like something you don't need running, leave it be. If it's something you installed from the Market, and you want it to auto-end, have a field day. If you put something on the auto-end list that the Atrix needs, it will just keep re-starting it. This draws processor time and battery and isn't worth it.
12. (credit: Itsallgood) Check your profile - "settings -> battery" and look at the bottom half of the screen. The Atrix supports multiple battery saving profiles that allows you to control "night time" and whether to actively sync data all the time, never, or only during certain hours. Push mail and active data sync consumes battery at a steady pace. In addition, 3rd party apps (like Settings Profiles) can be downloaded to further tweak and customize everything from vibrate mode, screen, data sync, and more. The more customized your experience to fit your needs only when you need specific services, the better your battery life will be.
Anyway - that's some to get started, feel free to add more!

You don't have to disable everything, but the things above such as the background data syncs serve no purpose other than to drain a battery. The sync will complete during the next wifi connection and by time you access your contacts it will be done. Besides it'd not like all your contacts change every 30 minutes.
The idea is not so much to limit the experience of android, but to remove the unused features that do nothing for.you. I mean who really needs a youtube widget when the shortcut gets you to youtube just as easily and doesn't drain your battery.
It's the same idea as startup programs on your computer. They serve no purpose other than to slow your system down. Sure quicktime or itunes might load a few seconds faster, but how often do you really load those programs.

Definitely a good list of things, but felt like commenting on the live wallpapers thing. From what I've experienced, it seems like it depends a lot on the wallpaper used. I initially thought the live wallpaper was one of the main reasons for the short battery life when I first got the phone so I switched to a normal wallpaper. I had that for about a week and generally saw a lot of improvements in battery life as a result of better management and the calibration cycles. After that week, I came across a live wallpaper I liked and decided to enjoy that feature for a bit more. If anything, it seemed like my battery life got a bit better. I've tested it a little, and there's no doubt that some of my live wallpapers drain battery more than others. I've tried switching between a standard wallpaper and my live wallpaper (galaxy live) and I really don't see much of a difference, if any, between the 2.
Question: Does freezing the blur home screen (via titanium backup) disable the widgets on it? I'm assuming it does, since it essentially makes that home screen non-existent as far as the phone is concerned.

Darrell, There are some really good suggestions. They also apply to other android phones too probably. I had a myTouch4G for a week until I decided that T-Mob just wasn't as good a value to me as AT&T. So I went back. I'll get an Atrix soon, or maybe some Tegra that comes out in a month or 2.

How do you switch to Motoblur from Launcher Pro and back again? Will I lose the customization that I've done?
Edit: Home Launcher

Modern lithium batteries actually die faster if you fully drain them then recharge to full. I'm not saying you can't do it every so often for calibration purposes but it isn't recommended as a every day thing.
Sent from my MB860 using Tapatalk

We aren't running them down for the batteries health, but more so that the phone will understand what full and what dead actually is.
Do not do this often as there is no point. As for damaging the battery, one website says it is bad while others say it is good. Do so at your own risk. I do not have a degree in science, so I can not say either way, however the steps above done once the phone is calibrated will help.

Battery life in SwiftDroid (may apply to other ROMs too).

Hai,
Since nobody bothered to answer my call to track down what drains the battery I decided to just post my findings and you do with it whatever you like...
In recent couple of months I've been experiencing quite nice battery life, almost a week on standby, which is basically on par with original LG ROM. The trick is simple:
It's happening as long as the Gallery app is NOT running.
I don't know what this piece of software does but when it's loaded to memory it stays in there and ignores attempts to terminate it, doesn't sleep when phone wants to and eats battery in a matter of single day. Unfortunately it seems some other apps use it directly or indirectly, like when Wi-Fi starts and/or by Market for example. Thus my solution is just to force close the Gallery after I finish activities which seem to require it.
I don't know whether root of the problem is with the app itself (like, CM modifications made so it's more cool, at the price) or it's just something else unearthed by certain SwiftDroid's configuration. To anyone who wishes to furher investigate my sincerest good luck. And I'd be grateful if results were published too.

You do with your phone what it damned pleases you. In case you haven't noticed the battery life is most often reported as either standby time or call time. In my typical usage battery lasts no less than two or three days but what 'typical usage' means may mean totally different things to me and to you.

Hey guys, I have tryed to find same issue, but i dont seem to find anything that is exactly the same on this forum, yet i see it everywhere on the web/google.
I have a problem with my new 2weeks old note 3! It have problems maintaining a prober battery drain and its really pissing me off. I have to restart my phone everyday, its like its slowly building up overtime or overnight... mby even after i recharge it?
I wanted to post some links to my dropbox with screenshots of betterbatterystats and gsam battery, but cant right now because im new, so first up ill see if anyone have any idea without further explanation!
Im rdy to do allmost anything, but i have no idea how kernel and stuff like that can be fixed... :S
Heres some of the pictures from working and not working!

Pay attention to the deep sleep, no increase in 2hours...
I really like touchwiz, but I HATE that I am forced to have bad battery because of some retarded fault in kernel!!!

Wow that looks much better than betterbatterystats, atleast easyer to understand! seems its samsung push and exchange mail that is the top users.. Could they both go under the category as a android kernel?

if you don't use exchange corporate mail you can freeze both apks. I use touchdown app for my corporate email, so those apps are also freezed.

I use the build in calendar, and its synced with my work calendar, so i use "Microsoft exchange activesync" to keep it updated. Could that really be the killer? according to gsam battery monitor my exchange "mail" is only 0.6% battery use while Kernel (Android OS) is 28.2% then its Android-System and then rest is below 2%..
Gonna share some screenshots when its gonna be available for me! This is really annoying me, knowing the phone can easly function and have battery for 2days+ the way i use it!

When I have a battery drain the first thing I do is give the phone a soft reset. Switch your phone off, take the battery out for a minute, reinsert the battery, do a cache wipe (start up in recovery mode by press and hold VolumeUp-, Home- and On/Off-buttons at the same time, and choose "Wipe cache partition"), then reboot.
Usually that solves the problem. If not, then I will start investigating what is causing wake locks etc.
If everything fails, than I do a factory reset.
To my feeling, people in general tend to do the investigation too soon, leading to nothing and forget to do the soft reset first (which doesn't delete any settings, apps or data, so there's no reason not to try it).
I had an unexplainable battery drain two weeks ago, solved by a soft reset as described, perfect battery since.
In location services (in Google Maps) I've switched off Location History and Location Reporting, which are known battery drainers, but that's pretty much all I do to prevent battery drain. I did notice that Nova launcher takes more battery than the stock launcher, but not enough to skip using it (at least not for that reason).

Even though it don't delete any settings etc. it still helps for some time. but my mobile is as close to stock as it can be, I hardly use anything that could cause this, except if its from android itself/samsung installations. Which it seems to be!
How often do you have to do such a painful reset? in my eyes, thats something you have to do, if its Broken!
Starting to belive its exchange, mail_service.
That specific one have 92x wakes in 2hours and all most 2mins used. I Think thats what keeps my phone from having deep sleep going. but its weird cause I only have it syncing calendar, which also show as a specific thing under the "mail_service" and it have like x2 wakes and less than 2sec used...
Apparently this bug is not new! Come on google!

I have read some people having kernel problems. .. and they have fixed it with changing kernel..

Do anyone know a good kernel for note3 ?

Speeking of the devil: today my Note3 wouldn't go into deep sleep again. Solved it by again by a soft reset, but start to wonder what triggers it. In my case I suspect the Tomtom app that I used yesterday, which gives me other problems as well every now and then (e.g. when the phone goes into stand by while Tomtom is running in the background).
I guess doing a soft reset on a regular basis is something I should do to keep my phone happy. In that, smart phones are not that different from PC's, which tend to show instability after a while as well if you don't restart them regularly.
But I do agree: in a perfect world it should not be necessary.

Just to make a thing clear though, I am not looking for battery saving tips etc. that would ruin the point of having a smartphone, its all those cool features that makes it worth buying. But knowing it can work WITH all these features and Not drain the battery, makes me crazy mad(I am at the point of returning it as being "defect")! It just destroys my experience of having it when I know something is not right. And it wasnt exactly cheap..

Anyone know anything about this?? Do the Screenshots help anyone? I am so close to the decission of rooting and then change kernel and rom this weekend if I dont find out why my phone is using this amount of power, When I know it dont have to!!

I've the same issue too on my completely stock set! Can't figure out what exactly is the culprit though ...

I just got totally fed up with it, so i did a factory reset and done minimal account bindings. So far it's working! So now I will just pay super attention to What I install. So i know When it goes wrong!

having similar issues recently..
and I can't detect what's wrong with BBS either :/

I am also having the same issue with my Note 3. Always the same thing. Works OK for some time after a soft reset and then starts not deep sleeping properly. When viewing at Battery usage it usually shoes "Media" or "Android OS" or "IndexerServices" as the number one.
I am happy with my Note 3 but it is really annoying knowing that your battery is being wasted without real usage.
Have someone contacted samsung or google about this?

Nice knowing I'm not the only the one with this Android OS causing battery drain when phone is idling.
Not nice knowing there isn't a solution yet.

Lets keep this going, I am going to contact google about this when i figure out what it is, for now im just being super observing! I did a factory+cache reset this friday and now sunday evening its still working(didnt even charge it all weekend!!!)(https://www.dropbox.com/s/khjosuw9t207paf/Screenshot_2013-12-01-19-35-23.png) I havnt synced it with much yet, but I have a little bee buzzing in my ear, telling me that its very likely something with the samsung_push service/email. So atm I have NOT added any email to the phone. Going to charge it up over night, use it normally all day tomorrow AND- if it still works, ill then at evening add my work email and then do this kinda step by step and check when it ****s up. Cause who am I kidding, if I just contact google/samsung now, they wouldnt care ****.

any updates on this mystery?

Wakelocks

Well, I've been searching for days on this so hopefully someone here has some insight on this.
I'm having some pretty bad wakelock issues, and I can't figure out what's causing this. I'd rather not root the device, since I have Nexus Protect and don't want to risk voiding that, so the tools I'm left with to figure out what's causing this are a bit primitive.
I read somewhere that Bluetooth scanning can cause wakelock issues like this, so I turned that off yesterday. So far today, the results are the same.
Screenshots: http://imgur.com/a/HltQ7
As you can see, I've barely been using the thing at all, and yet it's been awake almost constantly since I left for work this morning. As far as widgets, all I'm using are Google Clock, Google Calendar, and Weather Timeline. I have multiple Google accounts connected to the phone, but only one with synced items (and only what's absolutely necessary. Naturally, I've cleared app cache and system cache and rebooted, and I do not have Facebook or Messenger installed.

To be fair, we need a little more info including the build you're on. The changes you're making are small and clearly not changing anything for you. The multiple accounts are a possibility, and you could try syncing them and then turning sync off, or deleting them and beginning again. You could try booting in safe mode and testing it that way.
Personally, I'd back up the device, unlock the bootloader, flash the latest factory image and set up again (which is often el goog's advice) to see if the issue recurs. If it does you relock the bootloader and get onto Nexus Protect.

Unfortunately you're not going to be able to properly investigate what's causing the wakelocks without root. Any accurate app that can investigate this, like BetterBatteryStats, requires root.

so it seems that google search is the number one thing killing your battery. Try disabling that for a day or two and see how your battery fairs.
Like others have said, you can't really find out what specifically is causing the wakelock without root. Rooting your nexus will not affect your nexus protect warranty. You can restore it to stock very easily by flashing system in fastboot

Well I bit the bullet and rooted my device today, so I'll be able to take a closer look at this after normal use tomorrow - but currently I'm thinking it could be due (at least in part) to my workplace WiFi configuration. On my home network the wakelocks are pretty normal, but whenever I'm on the workplace WiFi it's held awake constantly. Upon disabling WiFi I'm seeing FAR more reasonable Awake frequency/times: http://imgur.com/dYstikJ

Amplify, greenify and autostarts, sort of deals with everything.

Also I wouldn't leave bbs or battery monitors on your phone when you're not wake lock hunting. As they tend to burn battery themselves

BBS doesn't sap battery at all. Well, not enough to matter anyway.

That's actually not true
It definitely had an impact.
My point is, don't leave it on there is you've found the issue. There is no point.

Show me some corroborating data on this and I'll eat my words. I agree that there are some battery apps out there that waste a lot of resources (I'm looking at you, Cheetah Mobile), but BBS is not one of them.

Just to further clarify what I'm saying, the app doesn't run in the background, it only runs when you open it and simply retrieves the data that is already generated at a system level. From the OP in the BBS thread:
BetterBatteryStats is calling the "batteryinfo" service of Android to retrieve data already lying there without generating overhead. Since Kitkat Google has revoked the permission for normal apps to access these stats (without valid reasons IMHO). You can read more about that here.

Mate I will have to do some looking into it. I already removed the application as I saw it burn down battery more as it was installed, why would I say it if it wasn't true lol, how do I benefit here?
I bought the app. Its not an apk and I'm not trying to be disrespectful here either but I saw drain. It's going to be a pain and I have very little time anyway in my life but ok. I'll get you some proof.
Actively collaborating data on that level has to have an implication on power, if it's symptoms reading a file then why do we need the app? Why not just read the file ourselves?
That's not me suggesting it, that's just common sense, surely you can see that prior to me proving it.

See my other reply. The app only runs when you open it and it refreshes then and only then, no running in the background. It's pulling existing data that's already generated by the OS. Sure, it uses power, I'm not denying that (any app has to use power). What I'm saying is it only uses power when you're actually in the app, nowhere near enough to have a noticeable impact on battery life.

I don't deny what you're saying. All I know is it uses power mate. Why have something running when you've anyway used it to fix what you can?
Amplify does a better job on its own.

It doesn't claim to save any power, it's simply a tool for investigating power usage. I run it constantly, I use it to check how often certain apps are waking, or to check screen-on time and the amount of time the phone is awake while not actually in use. The point I'm making is it's virtually impossible for this app to use an amount of power that would have a noticeable impact on battery life, because of the fact that it only runs when you actually open it. You open it, it gathers existing data that has already been collected external to the app, you view the data, you close the app, it's no longer running.
Amplify is a completely different app, and it actually does have to run in the background, so if anything Amplify would use significantly more power than BBS.
