So I'm considering either trying to exchange my GNex itself or my extended battery. I simply cannot get the battery life that most people, including my personal friends who have the device, are showing. My battery graph is never smooth and rockets downward at awkward angles. I've tried stock, many different roms/combos of kernels. I've also tried most battery tweaks I have seen. I had the Android OS bug originally, though after I tried out the 4.0.4 update it seems to be fixed. Nothing seems to be working. As an example, I had 15% battery left after 10 hours yesterday with no voice calls, 35 mins of screen time (barely anything), and having used no apps besides texting and a small amount of browsing. On the extended battery, that's fairly terrible. A voice call of 15 minutes will drain my battery about 10%. Nav will drain about a percent a minute.
Also, I live in a major city and never have signal issues. However, I am on wifi about 90% of the day. My brightness is always set around 15%.
As a test, today I flashed stock GummyNex and install absolutely no applications besides BetterBatteryStats. I currently have 30 minutes of screen time, and 15 minutes of voice calls, and have done nothing else besides a couple texts/a few minutes of web browsing. My results are fairly bad for having absolutely no applications installed or running, especially on a fresh install. If I had other apps installed and some things syncing, or if I had used my phone like a normal person and done anything else besides very minimal browsing, my phone would have died a while ago.
I'm attaching a few screenshots of when my phone was at 50% with this fresh GummyNex.
So the question is, could there be a hardware issue here that is stopping me from having reasonable battery life? Should I try to get an exchange?
Exchange it, I'm on my 4th Gnexus due to signal issues and have experienced the battery length differ from phone to phone, am about to exchange this one due to the flash led not working lol.

Good question, meant to mention that. I almost always turn 4g off. However, I am on wifi 90% of the time regardless.

Did you have much trouble exchanging it? What did you tell Verizon was your problem?

I have the extended GSM battery but even with my original battery I got more than a day as long as I wasn't playing where's my water constantly.
I turn off WiFi when the screen is off, I figure data plan can pick up stuff.

Hey guys!
I'm brand new with the galaxy nexus! I just came over from the Atrix 2 forums, and am really enjoying the phone so far! Anyways, i have a really peculiar problem that I can't find the root of. Say after 8 hours my phone will be reporting around 50% battery. If I restart for any reason though, when the phone boots again the battery percentage has dropped significantly, Usually to around 15%. Even after wiping battery stats and doing a clean wipe I'm still having this issue. I've experienced this on both AOKP and CM10.1 nightlies. Any ideas? Thanks!

It is a bug we have over at the n4 as well, 4.2.1 doesn't report the battery accurately. It'll not drop for several minutes past the ~5,5 minutes per 1% increment for regular screen time in order to then suddenly drop 2-3 % in seconds. A reboot can set it back 5-15% of battery, shocking but not a true value.
Hopefully 4.2.2 is around the corner and is fixing all that.. :good:
So it has happened a couple times where the tablet says it has 28% or so and then my daughter uses it and in about 5 min the battery is dead. Has this ever happened to anyone, is it from being uncharged for a while and by that I mean I haven't charged it for about 3 days? Its not to big of a deal just weird.

Probably just a calibration issue. Charge it back to 100% and keep and eye on it to see if something similar happens again.

I've had that problem, particularly when using what I assume are labor-intensive apps (Skype, Candy Crush, The Room). It really bugs me, since the tablet ought to be able to handle these without significant drain. But I'll see my battery go from 40% to 5% in a matter of minutes.

I made this account just for this EXACT issue..... same thing has been happening to me, battery loses CHUNKS in the matter of seconds, its not a calibration issue, i have fully charged it many times.
i just got not even 5 hours of screen on time with my note.... freekin pathetic. its a fresh flash of clean rom too. battery drain like crazy... i think im gonna try to odin to stock and send it to samsung... i think this tab has a battery defect.
Ya it only happens for me when the battery is getting lower at around 40-35% then sometimes it just drops stupid fast. Also I'm not rooted it's a stock tab
Sent from my SPH-L710 using xda app-developers app
I have the exact same thing. From about 30 - 35% it drops in a matter of minutes until empty.
Did anyone figure out yet what causes this? And is there a solution to it? I also sometimes have issues to power on the device. When pressing the power button it doesn't respond. I had this a few times now, after pressing the button for about 10-15 seconds it finally switches on... Anyone else had this issue too?
Yes im having the same problem. As im viewing this post, ive lost about 3% battery. Last time i buy a samsung tablet. They dont optimize or update to patch their mistakes. Horrible.
Sent from my SM-P600 using xda app-developers app
I had the exact same problem......
And the solution is.....
FORGET ABOUT IT... I know that it turns u crazy and makes u just watching the battery percentage waiting for it to drop....so annoying
But what I decided to do is just forgetting about it and use it normally and dont let the battery percentage go too low and by time and charging and draining the battery over a month or so it became perfect!! It even gets charged in less time (about 4 hrs)
agree
This has now happened to me twice. Id be hovering at 35% ish, and in 20 mins of video watching im down to 16%. Something is amiss
I never had this problem until i recently Rooted the device and installed Clean ROM. Im thinking i should go back to stock firmware with Root and see if this still occurs. Worrying
If people let the battrey drop to 5% then switch off the device. Then put it back on and then connect charger and charge to 100% in one go without using until it tells you to unplug....see if that works.
Obvs dont always do this....this is just to try to calibrate battery. Under normal conditions you shouldnt let the battery drop below 30% before charging anyway to protect the battery from severe degredation.

Had the same issue with mine, sent it to Samsung for what I thought was going to be a battery replacement. They just flashed a new firmware on it and that fixed it. They also put 2-3 scratches on my flawless screen. Idiots.
However, overall, battery life SUCKS on this tablet. It's way worse than the older 10.1 which I am using now because I can't get rid of Samsung's API locked sPen gestures on the 2014.

The problem might lie in the usage of a certain app... dolphin browser for example... enable flash on it and your tablet drops 10 percent a minute or more ... you should look if the tablet is draining also by doing nothing by just having the screen on.... there is also the possability of having a bad external sd card that causes android to loop media scanning nonstop....
Im rocking android for some time now on multiple devices... and it was always some rouge app which caused this ... causing wakelocks and stuff... you can look for whats draining battery with wakelock battery monitor... or better battery stats... try to keep android as clean as possible ... some apps just drain like hell.... even facebook ... because of background services

Youre using dolphin ? ... and yea stock ftw... just debloat with titanium .. look what runs in background and freeze whats unnecceary.... everything that runs unneccery drains battery... my note 10.1 Is on stock and clean as it can be... 10 percent per hour drop..
Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?
Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.
So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...
How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.
I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.
Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.
Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.
I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag
I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.
Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.
I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten
Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.
Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.
So, my battery is wack... and I think it's only been acting like this since I went to a KK ROM? Maybe? Feels like it...
I've had this tablet since it was released last fall, and this behavior is very recent.
Anyways, it dies FAST. Like nose dives in a matter of 5-15 minutes. What's even weirder, is that sometimes, if I power cycle the device, it'll jump up by 30-60%. But then just dies again in another 5-15 minutes.
And there's a screenshot after I just power-cycled.
It jumped from 11% to 71%!!
Crazy!
I've also tried letting it get to 5% then charging it to 100%, done that twice. No luck. I don't know if this is related, but if I power it completely off, and plug it in, it turns on... kinda weird. My Note 3 doesn't do that, it just stays off and shows the battery charge indicator.

Hi, I have similar problem and I am with 4.3 android. I have battery loss when I play games. It drops to 2-3% really fast and after reboot it goes up to 35-40%. Once I fully depleted my battery and charge it. This time there were no battery lost. After the second charging problem persists.
If you manage to fixed it please tell us how.

at first i was amazed of the battery life i use it a lot for work writing documents and sheets on excel, battery used to perfom quite well giving me more than 5 hours of screen on, but recently the battery starts to drop very fast, now i can barely get around 2 hours of screen on.
i've already done 2 cycles of full discharge and then charge it completely with the tablet turned off. but the problem stills.
also sometimes when i reboot the tablet the battery goes from i.e 20% to 40% after the reboot.
im still looking for a fix or solution, today i found a new official firmware for my model (4.4 firmware for telcel mexico). going to wait until the tablet is fully charged and then flash the new firmware. I dont know if its going to help but i got nothing to lose.
by the way, sending it to semsung is not an option because of knox 0x1

Man i ha e exactly the same problem. I calibrated it some months ago and it seemed to work fine. Now the problem is back.... Dont know what to do... I have tried several apps, though i read google doesn't recomend to use any app to fix the battery... we really need help here

Sent from my SM-P600 using XDA Free mobile app
Sorry to bump this, has anyone found a solution yet.
I've replaced the battery 3 times in about 9 months, but had this issue about a yr, was sent back to Samsung who changed the battery and supposedly updated the fw 4.4.2, I have since replaced the battery another 3 times every 3 months, each time either factory resetting or flashing a new rom, currently on official Smp600 5.1.1 BTU rom, today my battery was on 47%, I plugged in charger and was watching/streaming a movie on it, about 80 minutes later the tablet shut off, which was odd it's never powered off while on charge, powered it back on and battery said 19%, my previous issues has been the same as others, it can be on 100%, play a game, or stream a movie,or watch youtube etc and it will nosedive dramatically 20/30% at a time, sometimes within 10 mins it's gone from 100% to less than 30%, it's clear there's some sort of issue if others have it, I was wondering if a thread should be made to list ppl with this issue to see how many there are and go from there.

I've been having the same issue for some time now. Calibrating the battery does help, I don't experience the problem nearly as much after calibrating it. But it'll still nosedive on occasion, maybe once a week. This is the app I use to calibrate it https://play.google.com/store/apps/details?id=com.nema.batterycalibration
