[Q] Help reading better battery stats?

Hi everyone,
I have been lurking the better battery stats thread to see what was killing battery life of my verizon nexus and trouble shot what everyone recommended.
uninstalled facebook, google+, turned off gps/location, signed off google talk/voice etc i didnt even know i was signed into.
ran this last night for a total of 8 hours fully charged and still noticed a 20% drop from 100-80 same as BEFORE!
I observed alarm manager and lightflow were killing my battery. I can uninstall lightflow, but what is alarm manager? I don't have my alarm clock turned on.
Attached is the text log if anyone can help. It will be greatly appreciated =(

According to your log only 0.3% was drained due to your alarm, and that seemed to be the largest drain in terms of partial wakelocks...which compared to my 10% for RILJ AND 8% FOR AudioOut_1 on 4.0.3 looks like you should be doing excellent in terms of battery life as long as your screen was off.
Could you send a screenshot of your battery screen and battery history screen?

I didn't save it sorry but when I observed it. I noticed there were 3 times during the night there was awake activity so something woke up my cdma nexus. I am thinking it is probably my Google backup services and sync.
I have been reading other users only getting 1% drain every 2 hours and I don't think its possible unless they are on probably the GSM version.
I'm quite disappointed in the idle drain so far since I'm experiencing about 2% every hour.

While we are on the subject.....I have uploaded mine too
Is 4.4% alarm normal?

I'm still trying to troubleshoot my CDMA Galaxy Nexus in terms of what's eating its battery. The Android OS has been consistently higher than anything else (even the screen) and I usually see about 2-3 hours of awake time because of it, when I'll only use between an hour or two of screen time.
It's looking like an ICS thing more than anything else at this point. I can't really say that for sure since I'm still trying to cancel things out one by one to see any noticeable difference.
On the topic of alarms my AlarmManager only took about .3% today as my actual alarm clock took about .4%, whether what's normal or not I'm not sure anyone can say with the devices being so new and little information about that specifically.

its my understanding that alarmmanager has nothing to do with the alarm clock, but instead it is related internally to the OS that tells apps to wake up and perform some function. basically a scheduler for any app to tie into to perform an event, i.e. update the battery percentage, synch an account, etc.
i could be totally wrong on that though. and yes i think you guys with CDMA version have more trouble with idle. i still get dead flat idle drain on my gsm version...it loses 1% every 2 hours or so give or take. fall asleep with 95% and wake up with 91%!!

I'm also having similar problems with my LTE Galaxy Nexus. I can't figure out what is eating up the battery, but just now I had it sitting next to me in bed, unplugged, for about an hour and when I went to pick it up just now the back was really hot.
I'm not sure if I'm reading it correctly, but it looks like NotificationService is triggering a lot more wakelocks than it should be. I don't know what AudioOut_1 is, but I can't imagine it should be that active, either, since I'm not playing any music or getting a lot of notifications with sound appearing, but maybe that's not what it's for.
Any way I can pinpoint this problem any further?

guys, I am actually in a rather helpful mood today..

If that was helpful (which it isn't), I wouldn't be here right now. That goes full circle right back to this thread, and other threads with people asking similar questions about how to read the BBS data.
Something is keeping my phone awake nonstop, and I can't pinpoint it at all. Something registering as Android OS in the stock battery stats is eating up a large chunk of my battery and is preventing any sleep (which is, in turn, preventing wifi from disabling itself).
There was about 8 hours worth of data here before I plugged it back in, but Awake was a solid blue bar all the way across, along with WiFi, indicating that something is keeping it awake 24/7.
I'm sure that NotificationService is part of the problem, since it's giving me 1500+ partial wakelocks with over an hour's worth of time, however I have no clue what exactly is triggering NotificationService.
If there's any way I can pull the log file (I don't know where it saved to) and read the data somehow, is there any way that this can tell me what app would be causing this? I've already uninstalled several apps that I thought could be problematic and disabled sync on most of them (or set them to push), and I'm left with no answers at this point.
If there's something painfully obvious that's posted from the other threads, then I apologize for not understanding, however I can't seem to find any real answers anywhere; only the same questions and some speculative answers with no real conclusion.

well, there are plenty of ppl there that will help you read it since it is the app thread. The developer is also there and provides good suggestions.
Amazing though, lmgtfy failed even this time...

I'm thinking I may have a more severe problem than I once thought.
I've left my GNex sitting on the charger for about an hour now, to let it run its course and maybe give me some new data to work with. It's acting as if it's been on the battery for only ten seconds (which is closer to how long it's been since I turned the screen back on, but still charging), and then only gives me a graph for 11 minutes' worth of time.
One thing I'm seeing here which is probably a major problem is that the Awake, Screen On, and Charging meters all completely stop together at the same time for a moment, and then come back on. Even though the phone had been charging for well over an hour with no interruption, it looks like the device lost track of the charging status or something.
I'm not sure if the rest of this is relevant, but about an hour ago when I last put it on to charge, the phone app stopped working. Any call I'd make would immediately say "Call ended" without attempting to dial, even though I had a signal. After struggling with it for a few minutes, the phone crashed completely and reboot. Once it booted back up, the phone app would simply close itself and go back to the homescreen any time I'd try to dial a number, and was randomly adjusting the volume of the DTMF tones. It took about five minutes for it to actually allow me to make a call again, which doesn't seem normal.
So now I'm wondering if there's something else wrong with this device, or if this is all just a part of some bigger, underlying problem.
Worth mentioning, this is the LTE version, non-rooted, running stock 4.0.2.

I've been thinking about it, but holding off because I don't want to reconfigure all my apps/widgets all over again.
What advantages are there to AOKP over other ROMs?

[Q]Battery sometime takes a nose-dive when in range of the microcell. Anyone else?

I was late for work because my phone died completely unexpectedly and took my alarm clock function with it.

This isn't the first time there has been an inexplicable battery-life nose-dive causing me to miss an alarm *and* making me unreachable by anyone I might be holding up while late (Grrrr....). I'm pretty sure it's caused by the microcell, even though it wasn't connected (most phone will not connect without toggling airplane mode).
You can see where I was watching some Youtube videos and ran it down to 5% before putting it on charge around 4:15PM yesterday afternoon. After getting it charged to over 50% capacity, it then began dropping rapidly when I disconnected it, which wasn't noticed before I left home for dinner and a movie at 4:45PM.
Thanks a lot, Google, for not giving me the MUCH DEMANDED numeric battery percentage indicator.
Anyway, it hovered around 50% for several hours. I left my brother's place at around 1:00AM this morning, even though I knew I needed to get up at 06:10AM at the latest for work. I turned on the alarm when I got home around 01:30AM and got the message that the alarm was set for 4 hours and 37 minutes from now, which was more sleep than I've been getting but I wasn't going to waste any more time getting to sleep (just switched from 3rd to 1st shift). The battery indicator still showed about 50% and, as is often the case, my chargers and cables were packed up in the car for work the next day.
It had just gone over 8.5 hours without a notable drop in battery life (still over 50%; an imperceptible drop on the graphical status bar indicator), so why would I expect it to be unable to last another 4.5 hours on standby?! Getting my stuff from the car and packing it up again in the morning or setting an alarm on a redundant device takes more time and I wasn't about to deprive myself of more sleep when the phone SHOULD have been able to do this.
Well, I've had this happen before, so I at least took the precaution of turning off WiFi and Bluetooth, both of which had been on the entire day previously. Not only has it happened before, but I exchanged the phone... twice AND bought a second OEM battery with Sony Ericsson EP900 charger.
Anyway, the phone was locked in standby, as confirmed 100% when I woke up at 05:15AM to use the restroom. Didn't matter though: The battery life still tanked like the most intense of gaming sessions while sharing HSPA+ data over WiFi with a torrenting notebook! There was nothing in the list of what consumed what percentage to account for the drop. Sure enough, I woke up at 06:37, which was almost 30 minutes late and already well past the time I needed to have left home. !$#@%$#!
This only seems to happen at home, where I have an AT&T microcell. It almost never gets on the useless microcell without toggling airplane mode, which is not unique to this phone (confirmed with iPhone 3GS and two iPhone 4 handsets). It'll just sit there saying "no signal" or sit there holding on to the weakest of 3G/HSPA+ signals while standing right next to the damned thing. Also, the microcell drops calls when sitting right next to it and can't seem to ever successfully hand-off to Edge or 3G towers without also dropping the call (instantly reconnects with a full-strength signal meaning that there was plenty of surrounding signal strength outdoors). On top of that, the other party will often suddenly be unable to hear you even though the signal is perfect and you can hear them fine. When that happens, it may drop in about a minute if the other party doesn't hangup sooner when you "stop answering."
I'm unplugging the thing right away regardless. Screw AT&T. Even if it's not the cause of this particular problem, I can't believe my brother paid for this useless thing that makes everything worse. I'd just like to know if anyone else has had this issue so that I can conclusively determine if the microcell is related or not before I wear out my two batteries.

The battery life on my Xperia Play is crap as well. It'll just drain when just scrolling through the menus and even when playing simple stuff like emulators.
I can get maybe an hour of gaming.

That's not what I'm talking about AT ALL. I'm saying that it sometimes nose-dives when I am at home when sleeping/idling for seemingly no reason even when it has been fine all day and I have FURTHER reduced drainage by turning off features. My notorious microcell is at home and I feel that it's no coincidence.
The problem I am talking about can drain a full battery while you are asleep... less than 8 hours on standby/sleep.
If Android handled rebooting more elegantly and DIDN'T lose all the tabs I had open in the browser, I'd try rebooting every night to see if I still encounter the problem. I'd also be more sure that it isn't happening elsewhere if I had a numeric battery indicator when it is taken off the charger. So many SIMPLE things to improve usability.
While I'm on "simple" UI fixes, I've been having a lot of usability tweaks on my HP TouchPad with ICS. How about a way to tell which video in the freakin' LIST of videos I am currently watching WITHOUT having to pretend to want to email it to myself? Also, how about having a way to actually list the names of the videos instead of the thumbnails? An ES File Explorer is no better, with no alternate line colors and no way to enforce listing in one column, you will end up staring the same video three times before finding the first in the list you haven't watched! At least show the file I selected last time so that I don't select the same damned one again (put the same kind of selector a track ball or D-pad would leave). How about having a play button that isn't wedged between two other buttons I might not want to push and how about putting them a bit farther away from the area that will dismiss them if I touch it instead? How bout NOT putting them equally close to the progress indicator/scrubber? Gah! So. Much. FAIL.

AOKP has the battery percentage display you want, as well as other 3rd party apps. I'm sure there are other apps to replace the ones you're finding fault with, if you would just take the time to look into it. And new developments in custom kerlels have done a lot to address the battery drain issues in general. Finally, have you considered the possibility that your microcell unit might be defective and see about having it checked and serviced or replaced?
Oh, and about the alarm thing, invest in a clock. They sell pretty cheaply these days and it never hurts to have a backup plan!

Nokia CR-200 Wireless/NFC Car Mount

So I've been looking at these mounts and am on the fence about it. Costs a bit more than you would usually drop on a mount ($70-$100), but reviews of it are quite amazing. The sticky/suction pad is apparently really good, and the arms are stable and have a smooth release. On top of that it has a built in NFC chip. Now the Wireless Charging is where i get a little iffy. This device puts out 750mA. Comparitively the Nexus 4 charging orb puts out 1,000mA. I also have read in various places that some of Nokia's wireless chargers have a cycle issue where the device charges/stops/charges/stops. This effect might be visible on a Nexus 4 using this charger at this video (53seconds). Anyone have one they can test, or have recommendations to a similar mount?

I've read a lot of reviews about a critical part breaking easily.
Sent from my SGS3.

So, did anyone tried it? Does it work with Nexus 5?
From the info that i could dig, the nexus 4 does not work, probably because the location of the charging coil.

From what I've read and researched, the problem wasn't with Nokia's chargers but the first versions of the N4, later revisions worked fine.

When you put a Nexus 5 in the Nokia CR 200 it initially shows charging. Some time later (5, 10 ,30 seconds, maybe a few minutes - it seems to vary) it will stop charging. If you leave the phone in the dock, it will intermittently charge.
In my test over a couple of hours, the phone discharges pretty fast.
My conclusion is that it's useless as a charger for the Nexus 5.
If anyone has a workaround, I'd love to know, as the CR 200 is an otherwise sturdy bit of kit and I'm not sure what QI Wireless alternatives are available.

Thanks for letting us know. I've been actively seeking a qi car mount with nfc and this one was the prime choice aside from building my own. I wonder if it has to do with the bottom piece that sticks out for holding your phone in portrait mode, maybe the qi coils just aren't close enough together.

Nokia CR 200 works with Nexus 5 without any problems.
I received the Nokia cr 200 from Amazon yesterday and can confidently say it works brilliant. I haven't got any problems as mentioned in this thread. Just place the phone in the charger and the light at the bottom goes green and charged as it should. NFC is OK but got to know where the NFC chip is at the back of Nexus 5. I used the Google maps navigation and BT music streaming to my ford sony dab unit at the same time for about 50mins and the battery percentage just stays at the same level as before putting on charge. With BT music streaming it actually charges as the screen is switched off I guess. Its a good quality car mount but he clip is not the strongest I would say. Suction is absolutely fine as it has a stickiness to the suction. I don't know what app I got to use to check the charge voltage etc. Pls let me know if u want to know any details. But it works as it should very happy.

Out of curiousity, if NFC is so important, why not just buy an NFC sticker and slap it on there? Is it because it wouldn't look as cool?

have a look at what "OWL" has to offer...I ordered One....we'll See what this thing can Do.

More of a note to myself so I can find the thread again, but also just ordered one. Have a long car journey next week so should be able to give it a good run in, if it arrives in time.
Amazon seem to be doing it for £54 which seemed to be the cheapest outside of ebay

So it arrived today from Amazon and have had a bit of a play
Initial thoughts is that it is quite sturdy and looks good. Did the shake test and it did not come away, however a point of note is that it seems to grip but give it another squeeze to make it go a couple more notches in which kept the back flush with the charging plate. Just squeezing the grips until it makes contact won't hold it firmly in place and you get movement like on the Youtube review.
I've connected it to my bench supply as I'm at work. With the screen off/no GPS running its charges from 72% to 100% in just over an hour. The screen seems warm to touch and the back hotter which was expected. I've not had it been or connect/disconnect charging as mentioned in some reviews but I stress that this is on my desk at work.
Tonight drive home is about 40 min so will run TomTom and see if there is any power drop and tomorrow I have a 200 mile round trip so I can get some good testing done then as well. I'm hoping I will see the battery stay at the same level as when it was connected.
Does anyone have any suggestions of a launcher tailored to cars (car mode)?

Hi More testing done and I'm impressed so far.
Setting back home last night, I set TomTom up, the Settings of the phone was
GPS - Device Only
Automatic Backlight
TomTom in night mode
The battery at the start was 66% and at the end of the 2 1/2 hour journey it grew to 79%. So the phone charged while the screen was on and was using GPS.
Now admittedly this was not during the day, I did not have time to check the battery on the journey to the destination, however I did not notice any really drop in the battery from the icon. However halfway through the journey I noticed that the battery was not charging as I was rushing when I placed the phone in the cradle it was not fully flush with the back plate and/or I did not squeeze the clips that would hold it in place securely.
I need more testing but I think using this would be fine, potentially if you had full backlight and GPS running with TomTom in day mode I guess there may be a drop in the battery, but not much.

Next week when I have a chance I will attach it to my bench supply and do some testing at different levels of brightness and more than happy to test with bumpers/cases if people like to send them

I'm rather surprised by those of you getting it to charge, mine wouldn't put through enough charge when GPS, screen on and streaming music.

Battery Reporting/Phone Dying Suddenly

Update 2: I've had requests for links for the parts I used. I purchased the battery, a back cover, and all the additional accessories they suggested for removal.
Battery:
http://www.witrigs.com/oem-battery-for-sony-xperia-z1-compact
Back cover (this comes in different colors, but the link is for the black one):
http://www.witrigs.com/custom-back-cover-for-sony-xperia-z1-compact-black

Updating the OP. Thus far the only reliable way that myself and others have fixed their batteries has been by replacing them or having the phone repaired by Sony. Fixing it yourself involves purchasing a replacement from witrigs (or another parts supplier).
Flashing stock roms, custom roms (aosp or cm based), or factory firmware may temporarily give the illusion of being fixed. Battery repair apps don't do anything either (you can test this by 'fixing it', clearing app data and then 'fixing it' again).
I'm back to KitKat levels of battery life, using stock 5.0.2. Here's a recent screenshot for you.

Original post:
So for the past few weeks my phone has really been acting up. I'll try and make this an organized question/post.
Here's the symptoms:
-Phone drops from 30ish % down to 1%, then powers off and wont turn back on due to low battery.
-Phone occasionally reports fully charged at different levels (such as 80% or 50%), upon reboot, it is listed as 100%.
-Some days I can watch it drop 1% every few seconds once it reaches 35%, literally like it's counting down.
-Other days it just works fine, I can use it to 5% and then charge with no problems.
Phone information:
-Z1 Compact
-Problem persists between ROM flashes and android versions. Have experienced issues on stock 4.4.4, stock 5.0.1, AOSP 4.4.4 and AOSP 5.1.
Really, any sort of help or places to start would be greatly appreciated. I don't even know what to try anymore and I'd really like to avoid trying to replace it (warranty expired already).
Attached a screenshot illustrating it happening. I unplugged my phone last night after charging it to full. Made it to work, put it in airplane mode, turned wifi on. Updated some apps and restarted it. Rebooted to about 10%. Charging again now.

HI There,
i got the same problem with my z1 compact. its all start when upgrade to lolipop...
some say our battery are dying...or got problem. are they ?
downgrade to kitkat, wipe everthing, battery calibration also still the same problem appear...

I've tried the same thing. Wiped data system etc and nothing helped.

Same problem here. 4.4.4 stock rooted. It started about two weeks ago. I had done nothing except some play store upgrades. Haven't found a solution and I don't even know how to diagnose the problem. Various battery calibrations and/or deleting that battery data file haven't helped. Did a factory reset from recovery (almost accidental swipe while a bit drunk, gah...) - nothing. Battery level drop and shutdown occurs in random situations. Sometimes while taking a picture, sometimes with data on, sometimes off, gps on/off or whatever. Sometimes from 70% to 0, sometimes from 50%. Sometimes I can restart without charging after waiting a while and then it stays of for some time.
Yesterday I just did a reboot myself and when it came back on, the battery had dropped from 70 to 20% and then it stayed like that for some hours. Then I let it run to 0, charged without turning on to 100%. Then, when I turned the phone on, the battery level dropped to about 80% really fast and after that I got 20+ hours until it died again at 55% battery. I do see some small temperature spikes on Gsam battery monitor graph during those sudden drops, but never above 35 degrees Celsius and I don't think overheating is the issue here.
Again, I hadn't flashed any roms, updated android or messing around with the system or system settings before it started. Just normal everyday use, some websurfing, listening to music, taking occasional photos, reading blog feeds, taking notes.
Now I don't know what to do and I would greatly appreciate any help.
Haven't tried software repair yet, but what software could be still left broken?
Should I try unrooting via flashtool (does it lose all traces of root?) and taking it to warranty repair?
Right now the phone is practically unusable.

Hey, did u checked the Service menu Batterie test?
*#*#7378423#*#*
*#*#SERVICE#*#*
What does the test say?

I did check that yesterday and it was good.
And at the moment batt health status is "good, no need to replace it".
(Actual batt uAh: 2407000. Battery gauge at 74%.)
Yesterday after recharging and watching the battery plummet to 83%... It stayed there for some time despite data and GPS being on, using camera and an app. Should have dropped by a couple of % at least during that time.
13+ hours uptime now, very little use at night and at work.
That's what I'm afraid of. If the service test is good and at a glance everything seems to be fine then I won't get any help from warranty.

when test mine also in good condition. but the problem still happen. it kind makes me to conclude possible a battery hardware problem. need to change it, but it aint that cheap...

I've also checked my battery in the service menu. It reports good/healthy with the actual uAh being 2407000. I plan on wiping everything on the phone later today (system, all data, caches) and seeing if that helps at all, but I'm not very hopeful. Like you guys this pretty much just started happening for no discernible reason. Phone doesn't appear to be overheating either. Could the SD card being messing with it somehow? It seems implausible, but at this point I'm willing to try anything.

SOLVED (for me at least)
So I bit the bullet and wiped everything except for my SD card about 2 hours after my last post. Installed the most recent KK version of DstrikerZ1s ROM with the Doomlord v22 kernel. Ran it hard all day till now. Still at 50% and I've rebooted to check and make sure it's accurate multiple times. I'll report back if it happens again, but the performance thus far seems much more consistent than what I had before.

So need to format sdcard?
Sent from my D5503 using XDA Free mobile app

Yeah, I backed up both my internal storage and SD card and then formatted both.

wow, i have the same problem and i don't want to go back to KK. doees anyone have any solution that keeps lolli on?

I've been having the same problem since February. First it turned off at around 14% (when the warning pops up), but it's already been turning off at 20+ and finally 30-something percent, which wasn't bearable. No amount of wiping or up/downgrading would help so I bit the bullet and got a battery exchange (not directly from Sony who wanted to charge ~160€). Problem is fixed for the time being.
As much as I love this phone, it'll be the last one I get without a user-replacable battery.

Unfortunately my "fix" didn't work forever. I'm back to the same problem. Might as well suffer through it on lollipop. Where did you get the battery replaced?

So it was relatively easy to do yourself? I'm relatively nervous to try it. Shipping is killer to the states too :/

Yeah. It's pretty straight forward. I used my wife's hair dryer as a heat gun and followed witrigs guide. I was surprised to see a 30$ tax on my items though. But thats due to customs so i had ni choice.

need to unscrew 1 skrew only right?
Sent from my D5503 using XDA Free mobile app

exactly the same problem only since Lollipop update.
it'll just shut down about 30% battery now, no going into battery saving mode or anything, i'll just be messaging and get "shutting down". Also I've had 53% battery, rebooted and then have 80%ish, its completely messed it all up.
I've factory reset and cycled the battery (run down, charge full etc) more than once. I'm suprised peoples batteries actually need replacing, how can a software update damage the battery?
I remember with a previous rooted samsung phone you could delete a battery data file with root explorer or something, is there a similar non-root way to fix this problem?

battery goes for 15 percent straight to 10, then to 5, then dead.

so lately my battery is being annoying. I'll hit 15 percent, then outta nowhere it goes right to 10, then all of a sudden I hear the beeps again and my brightness lowers and i'm at 5. wtf?
then within like 30 seconds, it's dead and the phone is shutting off.
now, it did this before a factory reset, and again after one. I'm still in kitkat 4.4.4.
the battery status is fine, and it's not bloated or anything. I hardly ever use fast charging so I have trouble believing that within less than 1 year of the phone, the battery died already.
my battery life in general is garbage and i average maybe barely 3 hours screen on time a day at like 16 hours off charger... but what this is doing I've never had happen on a phone before.
any thoughts?

My wife's does the same thing. I believe it is a bad cell in the battery. Haven't bought a new battery to test my theory though.

hmm damn. i mean, i don't wanna waste the 40 or so bucks on a new battery when I'm considering the new nexus 5 when it comes out, ya know? status says health is fine and everything though. that sucks. never had a battery go bad on me before, especially in such short time.

Mine did the same thing, I thought it was because I left it in the car during the hot phoenix summers. I bought a new one from Samsung on Amazon for $13 (OEM) and it worked perfectly, and overheats less now too

wow samsung batteries are that cheap?
Sent from my Galaxy Note 4

so, I did the trick where you let the phone die then keep it off and charge it to 100, which some people said fixed it.
didn't do anything here. when i hit 10 percent, the phone just shut off. it was dead. makes no sense. like, when it shut off, it turned itself back on and tried booting. hit the Verizon splash screen, the lights came on, then shut off.. and tried booting up again. it was as if it's in a dead battery bootloop. once I plugged it in then it fully booted... and it was at 1 percent.
look at this screen shot. you can see where it died at 10 percent.
also, does anyone else's phone seem much laggier when it's charging? typing lags so hard when it's plugged in. this damn phone...

I take it you bought the phone straight out from Verizon?
If it's been less than a year since you got it (although they really don't pay attention to dates in my experience), call Verizon and ask for a warranty replacement w/ battery (If you bought it from them, not sure if they'll still do it if you got it elsewhere). Use the new battery to test the phone. If it's the battery, you just swap it out and send back, the phone they sent you.

true. I think at this point I'm just going to go buy a new battery. I'm going to get the one with the charger because it seems the ones on amazon are fakes according to the recent reviews. 40 bucks but eh let's see.

I have also been having this problem.... more often than I am comfortable with. And in my case, it goes from 30-40% (even 50% once) to zero in a flash.
Verizon support responded to my Tweets and they insist that it is software problem - one of my apps doing it.
This is what they told me:
" VZW Support @VZWSupport
We certainly want you to rely on your battery life to give you a great time with your phone. I've run the diagnostics and have some great news, the battery checks out. The plus side is it helps us narrow down the situation as it indicates it's software related.
I've noticed a few things including a few apps on the phone that may be contributing. We do have an awesome way to test it. Visit vz.to/1B30APG to see information on powering up the phone into safe mode.
That will leave the phone using only applications that came with it out of the box. I would suggest leaving it on safe mode for several hours to see if the battery drain continues.

damn that's bad. and God verizon are a bunch of morons. this isn't a software problem. it's a hardware problem. I've done a factory reset and it still does it.

Hate to side with samsung and verizon... i actually am not...they've pissed me off!! Loved my note 1,2,3...they broke my 4 and made a crap 5!!!! ...but I digress...
The 15% problem I do believe is a software issue. It started for me as soon as I did the lolipop upgrade. It happened to a friend of mine as soon as THEY did the lolipop upgrade. Besides the fact that 99-16% goes SOOO fast on lolipop...this is probably the single most disturbing thing since the upgrade... bleep *power off* CRAP! I didn't even get the phone out of my pocket yet!!!
AAAGGGHHHH!!!!

I'm on kitkat. not lolipop.

Mine was having the same battery issue dying at 15%. Got a free replacement battery thru insurance. Now it last as long as it did when I first bought the phone.

It's just guesswork on my part but it is probably the firmware issue rather than a battery issue.
I have purchased an extra battery with external charger.

i like how there's a steady decline over night with like no wake time lol was like 10 percent overnight.
Sent from my Galaxy Note 4

I think i broke my phone lol today for some reason it stayed at 100 percent for 4 hours off charger and 20 minutes screen on time. it has never ever done that. it drops fast from 100 to 90 within the first like 15 minutes of usage. makes absolutely no sense. damn battery.

pos went from 15, to 10, to 5, and powered off.
oh well. I ordered a moto x pure that comes tomorrow. time to give moto a try!
Sent from my Galaxy Note 4

had my Moto X for two weeks so the note has been off with the battery taken out. powered it on the other day and it had 65 percent.. where I left off 2 weeks ago. within 5 minutes of using the phone I got the low battery warning at 15 percent, then it dropped to 5 and shut off. I was like wtf?? I plugged it in when it was "dead" and it showed 55 percent battery left.
wtf is wrong with that thing??

Just FYI, mine is doing the same went from 40 to 15 to 5 and off. Been doing it a lot lately. Took it to Verizon and it passed a battery test. Since its within one year they are sending me a new phone. Will be here Tuesday.

Looks like I'm in the crap battery life club. I'm going to Verizon tomorrow or Sunday, in order to get a replacement. My handset speaker is screwed up as well. I liked this phone until I upgraded to Kitkat. It has been horrible ever since. I may try to flash my phone back to 4.4.4 to see if things get better.
