Hello,
so I got the bloated battery issue myself, and had to order another battery. I have seen many threads pop up in the last month concerning this issue, on here, androidcentral, and even the sprint forums!
There doesn't seem to be a unified thread, so I would like to try to get one going. Sprint/Samsung probably doesn't know how widespread this issue is becoming. I think its a more serious problem than we think, and isn't relagated to a few random people. Myself and my friend, who both got our phones around the same time, who both run the same build of ICS started exhibiting the following issues:
1. Insane and unpredictable battery life drops. I'm talking 88% while browsing the web, and then instant reboot and phone is down to 10%.
2. Screen flickers as if auto brightness can't make up its mind, instant reboot.
3. LOS, then reboot.
4. Any intensive apps: camera, gps, sometimes even just streaming music, causes the phone to lock up, pressing home does nothing, may even require reboot.
5. Removing battery, and then letting phone sit for 1-2 minutes, then putting it back in an powering up brings battery level back up to stable temporarily.
6. Battery Bloat, and inevitable: permadeath. Can't hold a charge.
This seems to me to be a consistent occurence along with recent builds of ICS.
I would like to get to the bottom of this. I don't plan on keeping this phone much longer (I ordered a Nexus 4, still in order limbo tho), but it could be of help to the community if we know the how's and why's.
Questions:
- Are you experience these symptoms?
- If so, when did they start, give a specific build number?
- Have you experienced battery bloat? (battery seems to be slightly expanding outward, not completely flat)
- Do you keep your phone on the charger overnight? (This may or may not be related, but maybe a recent ICS change disables something that stops the battery from overcharging)
Interesting! My wife had this exact issue on her E4GT unrooted FI27. Eventually, the phone would no longer boot. She took it back to Sprint yesterday. The battery was bad, they tried another battery and the phone still wouldn't boot. She's receiving a new phone today.
She told me when she was at the Sprint store, there was a guy there with an Evo with exactly the same problem. I told her it was just an amazing coincidence and not an Android issue... obviously I was wrong!
I am on FI27 stock rooted with a newer battery than my wife's, the only thing I have noticed is that my charge sometimes drops CONSIDERABLY after I reboot the phone... now this has me worried! Her battery was bloated. We both charge overnight.
Obviously, this is an issue that you can't ignore, because it can fry your phone (as it did my wife's).
Yes!! The insane battery dropped started happening like a month ago. That's all that was happening though. Just random battery drops. I thought it was the ROM at the time. The phone would freeze up, reboot and the battery would be 30%+ lower.
About a week ago I started experiencing the craziness. Phone rebooting, flickering screen, pretty much everything you've stated. And yes I've been using the latest modems. My battery can also spin like a top. For a very long time I might add. Some other dude with a regular Qwerty phone has a battery that can spin, but it only spins for like 3 seconds. His phone is pretty old.
My phone is about a year old and the battery spins for ever. I guess this is a good test to see how bloated your battery is, since I can't really look at it and tell.
I do charge over night since my phone would die over night. I don't think my phone will fry right now since my phone is on the charger and the battery temperature is at 66 Fahrenheit (18 Celsius). Ordered a new battery hoping for the best. And I will be using ROMs that are based on the FF18 with the new battery.
first power button broke, now battery is taking a **** upon itself, exact same issues
Check this out... as I said, after my wife had been having this issue for a couple weeks on her stock E4GT, on Thursday her phone would never boot past the boot screen. She took it into Sprint on Friday and they determined the battery was bad. They tried a new battery, still wouldn't get past the boot screen. They ordered her a new phone 'overnight' which is supposed to arrive Monday. She is going into withdrawal, so for the hell of it I plugged her phone in, booted to stock recovery and did a factory reset... reboot and the phone (apart from the bad battery) works perfectly. My wife asks why they wouldn't have done that at the Sprint store? What a bunch of idiots!

I have the above listed problems with my SOny Xperia Arc S after I updated it to ICS.. It is kinda frustrating..coz it turns on and off by itself, or sometimes it just froze that will makes me manually take out the battery..But when I haven't updated it to ICS there are no problems like this...

Do look in what forum you are replying to before replying. This is the E4GT forum. NOT Sony!
This is a specific problem related to E4GT. I think its the characteristics of this problem that make it unique, the instantly dead battery, the battery bloating, and something to do with recent ICS updates. I am hypothesizing that it has to do with battery overcharging that somehow got introduced to recent builds of ICS that is causing this.
I just got my new battery in yesterday, and sure enough, it fixed all of these problems. It's an Anker battery, and, although I am no expert on batteries, its a really nice third party battery, and feels weightier than the stock Samsung battery. Now I'm worried that ICS will destroy this battery as well, so I am being very conservative when it comes to charging.
I was having the same issue with my last E4GT running FI27 STOCK ROOTED.
1) LOS to reboot then low battery from full
2) using apps like spotify, maps and voice search on 3g would also cause it to reboot to low battery
3) screen flickers (like cm10 flicker) and then reboots

I don't think the issue is related to ics but rather the age of the phone, but i could be wrong.
Has anyone had their battery die after upgrading to ICS when their phone was less than 8 months old?

Pesonally, I agree... my belief is that this is a battery age issue. Now, I won't say that the battery should age so quickly or that it should start bloating, but no one has had this issue with a newish battery have they (say, newer than 6 months)?

I dunno man. I have had an Epic 4G, an HTC Evo, and evne HTC Hero that I kept for quite a while and their batteries never bloated and exhibited these kind of software based issues. Sure batteries degrade over time, but it's almost like the software was glitching out when it was killing my battery and causing strange reboots and lock ups, not to mention instant drain.
new battery bloating within 2 weeks

Hi there, first post here, I was just browsing the web for help with this issue and found this thread. My galaxy s2 eg4 also had the bloated battery after ics update, it was shutting off randomly, flickering, etc. I replaced the battery first part of december 2012, and within 2 weeks it had started doing the same thing again, but not as often. Sure enough, brand new, previously flat battery was slightly bloated. It has gradually gotten worse, so I just purchased 2 new anker batteries to see if they fare better. When I changed the battery and took out my one month old battery, it was quite bloated and spun for quite a while.
Hoping it does better with the anker batteries, but only time will tell.
Batteries bloating has nothing to do with ICS or the software. Its a heat issue and weak cell walls inside the OEM batteries. The cell walls barely meet requirements to make the 1800mah cells fit in a 1500mah size housing and they don't hold up well to high temps. as the battery reaches 120°F+ the solid state chemicals used in the cells begin to expand, a normal battery's cell walls can withstand the slight increase in pressure but the thinner walls in these batteries begin to crack and/or separate from the housing and then the chemicals can mix. Once the chemicals begin to mix the reaction causes the air inside the battery to expand and swells the housing out as it has nowhere to escape.

I have the same problem l. Even with a 3800mah battery. It will start.acting up and if it gets better it will all of sidden go up to 70% or more, and i know it takes a couple of hours to get it to 70% from being dead at 15% or less.

I have been using the anker battery for over two weeks and no issues, longer battery life, etc. So far, so good. :fingers-crossed:
Most definitely a battery issue, especially when your phone is a year old or close to it, I don't know what was up with ics but that sure put hurting on the Epic Touch.
I have two Epic's and they are both 14 months old and in Dec they both got new batteries, an Anker and a original Samsung and they are both running like new again. Ones on GB and the other is on JB roms.
They both experienced the bloted battery syndrome and they also experienced ics, for a short period before going back to GB and now JB. Ics was a catalyst for the batteries to fail the way they did, not to mention that charging and discharging a battery for a year or so is going to also take a battery to its limits, especially when you plug it in overnight. At present we have no issues with our Epic's and we are just going to wait it out for the GS4 to get here before we upgrade.
EViL is on the right track even thought he likes to break stuff.

I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.
I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.
had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)
Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."
I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.
Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?
So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.
I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!
I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.
I thought I would check and see how much battery is used overnight on my Nexus. What I found was that the Android OS kept the device awake over half the time. Also, for some reason the phone used battery as well.
I'm running stock 4.0.2, rooted and unlocked... is this typical?
Yes, this is known bug:

Hey Guys -
I shut off location services and my battery drained only 9% in 8 hours of non use last night... It used to be around 25%. I'm thinking that Android keeps waking to check where you are... Just shutting off GPS is not enough as it will wake to find your location via wifi or cell towers.
Just my 2 cents. Give this a try to see if that helps you guys out. Google still needs to fix this but it might be a good temporary workaround.
Rob
I typically see around 8-10% battery drain overnight off the charger. And I thought I had problems. If you are losing 25% over night that seems unacceptable.

It actually dropped from 100% to 24% overnight which is almost 10% per hour.
i lose 1% in 1.5hrs, on standby in ATT HSPA+ network, i thought that was pretty good.

Roman has fixed it or at least it appears he has. I loaded his CDMA rom "[ROM] [AOSP] Android Open Kang Project - toro build 9 [Dec 21]" over at rootz and it is putting the phone to sleep when the screen is off. My phone had be staying awake 30 - 50% of the time prior to this. I've only had the rom loaded a short time, but in the last 40 minutes of non-use my Staying Awake time has been about 2 minutes. YMMV
Good luck.

Thanks for the reply... that's encouraging to hear. I'd like to stay stock for a while so hopefully 4.0.3 drops soon!
I know many people recommend rooting and using a custom rom, but I've had a poor experience with that. Having said that, I've been working on battery issues and this is a picture of my battery drain overnight. It basically took a nosedive.
What I don't understand is some people are getting great battery life from this phone. I've turned off all my widgets and followed many recommendations - but frankly I shouldn't have to do any of that and even so my battery life is abysmal.
Is there any answer to this problem short of rooting? Do I have any reason to believe that google will acknowledge and correct this issue?
By the way I had a Droid Razr for a month prior to the Nexus, and it would lose no more than 10% of it's battery overnight.
I do everything "wrong" (syncing, gps - wifi - data on) I have 5 widgets on my home screens and I loose less than a % per hour over night if not on the charger.
When I am using my phone I keep the screen on full brightness. This will get me about 12 hours of use with 4 hours screen on time.
I have no idea why some people get great battery life and others don't. There must be bugs floating around. Lets see what 4.0.3 brings. I'm unlocked and rooted but still stock.

That's the frustrating thing - it's working great for some people.
I have to return mine because the headphone jack doesn't do stereo, maybe I'll get lucky and the new one won't have signal and battery issues.
The Razr never dropped voice or data - the Nexus drops both multiple times during the day.

I would try a different radio. I wasn't exactly thrilled with reception at first. A North American radio changed that. But i would still give moto a step up on reception.
I think more people should also consider congestion in their city to how well battery life does. Can Make a big difference. Otoh though, that doesn't account for standby at night when you're asleep. It would seem to me no matter how your phone is setup 1% an hour should be the norm, unless your phone downloads a lot of data.

Ya, try swapping it, IDK... I have yet to drop a single call on my Nexus. One thing i can say is Samsung needs to look at their quality control. I definitely got a good one. I don't see the REAL problems others are having. The fact that most phones are fine, and some are duds is the one thing i will hold against Samsung. Gives a really good phone a bad name when so many have issues.
I can say its not all of them.

Thats just horrible idle drain. Something kept it awake you can see.
I feel bad cause my gsm version is literally the best idle drain phone ive ever had. It stays dead flat for me and last night i lost about 1% every 2 hours, and tgat is witg data on and two gmail syncing etc. Its just awesome. I think there is something wrong with tge verizon model. My phone is stock too.

Is it related to wifi? Noticed most of your drain was while wifi was off.
My grandma beat me down and took my nexus. Sent from a jitterbug with beats by dre.
I just tried a new ROM last night and had an improvement with my phone sleeping more of the time the screen was off yet the battery drain doubled to 3%/hour. Can someone explain how that makes sense? My phone slept 10 of 11 hours during this time. And the CPU was scaled down at 350 mhz by the kernel the entire time while the screen was off. So confused...

i have the same setup and loose less than 1% an hour, when the phone is idle
Thanks to the kind folks who have replied with questions, comments, or just sympathy
There are of course a lot of threads in this forum related to the Nexus battery life and I've been trying to do my own due diligence. I have removed every widget from the phone - even those which are just 'switches' and should not make any data requests. It was still draining.
Then I removed the fancy Light Flow lite app that gave me pretty notification lights - still drained.
Finally, I removed Battery Monitor Widget - the very app I was using to try to find the cause of my drain.
Took the phone off the charger at about 10:30 this morning. Used it for navigation for 20 minutes, ran the bluetooth for a bit and that took quite a bit off the battery. However, when I got home I forgot to turn the wifi on and set the phone down. Sitting there doing nothing connected to 4g the battery dropped less than 10% over three hours. I didn't look closely enough to see the exact numbers but overall I'm at 60% now after 6 hours of what I would call moderate use.
Most importantly, the phone seems to actually sleep now when not in use. I don't mind if the battery drops a bit faster during use - it has a great screen and wicked fast 4g. I just don't want it to tank when it's not doing anything.
For right now, it's acting exactly how I would expect and I'm very pleased. Will probably give it another day and then try to add back my beautiful widgets time/weather/calendar widget on the home screen and see what kind of damage that does. Maybe try a different battery widget as I like the percent left in the notification bar.
Good thing is, now I have a baseline that I'm happy with to measure my performance from.
Thanks again for those who've posted in this thread. Hope anyone else having similar issues might benefit from my experience.
And I'm right back where I started. Phone had insomnia last night. I took it off the charger at 100% last night at midnight and it died within five hours sitting on my night stand.
Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.
If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.
I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%
Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB
I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

I got over 30 hours last weekend with light use, but the next day, my battery would drain 5 to 10 percent per hour with no use. I have all the utilities to track what's happening, but cannot find a definitive cause. Poor reception seems to be a factor, but not the whole story.
EDIT: I just installed GSam. Thanks for the tip!
Try the Re-Calked FI03 and tell me ICS sucks....this things is as good if not better than Calkulins v3 GB rom....the ONLY other rom i have ever liked.... :good:

Maybe you should've posted this after receiving and using your new battery. My phone had horrible battery life after a while on ICS but it turned out that it was in fact the battery and not ICS. Got a new battery and it is back to 18 hours a day (on ICS)

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...
https://play.google.com/store/apps/...av_result#?t=W251bGwsMSwxLDMsImNjYzcxLmJtdyJd
Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.
Quick story that may help some other people:
I bought my Verizon Galaxy Nexus used on Craigslist. It was a good deal. Right away I bought the extended OEM battery as well as the Seidio extended battery. The first thing I noticed was that battery drain was unusually fast. I'm no noob to Android phones, and a few of my prior phones had bad reps for battery life (HTC Incredible, Samsung Nexus S, HTC Thunderbolt), but this was something special. For the first time in my life I felt the need to use Juice Defender, and that was only marginally helpful.
I never minded with the other phones because I would use the largest battery available, charge on my 40 min commute to work, charge on the commute home, and everything would be fine. The problem with the Galaxy Nexus is that not only would it drain fast. It would take unusually long to charge, espcially when using during a charge.
The next thing I noticed was that the phone was getting very hot, especially in the top left corner, even when it wasn't doing much. Turning off LTE seemed to help but not much. After a couple months of use, trying ROM after ROM, kernel after kernel, reverting to stock, etc, things took a turn for the worse. I would go to sleep with a pretty good charge and wake up the next morning with a dead battery. Sometimes the battery was so dead it wouldn't even take a charge.
I called Samsung, and they were very responsive. Even though I wasn't the original owner and had no proof of purchase, they paid shipping both ways and had my phone repaired and back in my hands within a week. The paperwork that came with the repaired phone just said that a "component" had been "replaced". I called and asked them which component was replaced, but they couldn't give me any more details than that.
My repaired phone gets warm sometimes, even very warm, but I haven't noticed that hot upper left corner. Meanwhile, the battery life is night and day better than it has ever been. I can get through the day fine with the Samsung OEM extended battery, and the Seidio lasts damn long like it should but never did. The batteries now charge much faster as well. I can finally enjoy this phone like it's supposed to be enjoyed, and I have no more thoughts about upgrading some time soon.
Maybe Samsung just has amazing customer service, but the speed with which they handled this as a warranty repair makes me wonder if this is a known issue on their end. In Googling for a solution to my problems, I came across other reports of people who found their battery suddenly dead, unable to take a charge.
Here's my advice: If your battery life is atrocious - and I mean atrocious even with the screen pretty dim, no accounts syncing, LTE disabled, factory stock with no apps installed...
and you find your Galaxy Nexus taking a long time to charge (using the OEM charging cable)...
and your G-Nex gets super hot in the upper left corner even when it isn't doing anything...
then try sending it in for a warranty repair. The phone I bought on Craigslist was defective, and after struggling with it for months, all it took was a one week repair and I'm 100% content. It's a completely different phone.
:good: glad you got it fixed
I've had the exact same issue recently, phone would get extremely hot especially with the screen on. Never had it not charge, but it would never stay at 100% very long while charging. Screen on time was pathetic and usually not much more than about 30 minutes.
Today, I decided on a whim to completely drain off my battery, phone wouldn't even turn on when I was done. Recharged to full with it off and it's running cool as a cucumber. 7.5 hours since I took it off charge and an hour of screen on with a bit of streaming over LTE and I'm still at 53% battery (whether that's good or not is questionable, but it's a massive improvement for me.)
Am I positive that's what fixed my phone? No, not at all. If it starts acting up again I'll probably talk to Sammy about a replacement, but for now I'm happy.

that's kinda bit questionable still. just an hour of screen time and almost half of battery means there's still a huge space for improvement
Almost half of that was streaming on LTE and in general being an attempt at eating battery and causing the heat issue to come back. Coupled with the fact that I live in the boonies and my signal is never stellar, I'm fairly happy with the time.

Good to know
Totally different outcome for me...
I had the exact same issue; slow charging, horrible battery life (even after a new battery and a factory reset). After two weeks without my phone, today I got it back. Not only did I get the same phone back (based on the serial number) I got the *same battery* back. This was also the result of a "replaced component" (which no one could tell me what it was).
edit: I should add, I bought this phone new from Google directly. It worked great from May until September when this problem suddenly started happening. Prior to September, I could easily get 2 days out of a charge with my typical usage. After it broke, I was lucky to get 8 hours, even while the phone was ~80% idle. You can see in the screen shot that the phone was burning around 8.8% an hour even while completely idle. I mentioned all this to the person who created the service request, but obviously that didn't make a difference.

I'm so disappointed, but I'm not even sure where to start. I will not go without my phone for another two weeks. I'm going to call tomorrow and see what they'll do, but for now I'm more than a little pissed off.
I'm on my third GN and they've all had this problem I replaced the first 2 directly from Sprint. Pretty fed up with the phone. Friends of mine have this phone and don't have any issues at all... what are the odds that I were to get 3 defective phones in a row?
I'd consider going through Samsung for warranty, but I can't go without a phone for up to 2 weeks.
Sorry you two have had such a bad experience. My replacement Nexus continues to be terrific. While my Nexus was in the shop, I used my old phone (Thunderbolt) and enjoyed the change during that time.

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

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.

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.
