1. Sometimes it shows its charging when its not.
2. I get a consistent low battery notification at 15%
3. And it get these weird power glitches.
Anyway if anyone could help. That word be great but I'm about to just call vzw and get a new phone.

!!!!!!UPDATE!!!
I called Verizon on Monday who told me it was a known issue and a software update would resolve it. However I told them to send me a replacement anyway.
Now today..I plugged the phone into my USB cable connected to my computer and it started smoking!! I swear I zapped something. It still works, but now its all weird. I going to have to use the wireless process of getting it back to stock and locked..so we will see how it goes.

We need more information.. did you do anything on your phone that might have done this? Can you confirm that battery is fine?

Not that I know of, its running CM10 Euroskank.
I also noticed that when I plug it in to the charger it takes about 10 seconds for it to recognize that I plugged it in and start charging.
I had a similar issue on the GSM 4.1.1 stock ROM where the battery voltage was being misreported (using Battery Monitor Widget to check values). Sometimes the voltage didn't decrease with use; sometimes it even increased without being charged - your battery graph seems to show this too.
This problem developed literally overnight and didn't rectify itself over multiple charge/discharge cycles. I changed ROMs to see what would happen and to my relief there were no further problems.
As an option you could try clearing the battery stats in recovery.
Given that a few people in this forum have had sudden battery weirdness, and that a fresh ROM fixed it for me, I suspect there's a rare software bug at work here...

-1 on the clearing of battery stats. It has absolutely nothing to do with it. He'd get the exact same results by changing his ringtone or something else that's totally irrelevant.
Battery stats has nothing to do with the reported percentage of battery. It cannot cause power problems. And it will not affect battery life.
How is it that the wives' tale of clearing battery stats still persists despite the fact that a Google engineer has debunked the myth and that debunking has received wide publicity within the android community?

I had a very similar problem with galaxy s2. My symptoms were that it thought it was charging when it wasn't, it thought it was usb connected when it wasn't, and my battery graph would just show one long spikey graph for as long as the phone was on. I posted it up and someone clever identified the problem straight away; a short in the usb charging area.
Have you ever spilt any liquid near the usb charging port? It's a replaceable part and I'm sure it's available from the usual place (ie. Ebay).

Also, the text file that has the "battery stats" is erased when you reboot, which is the same as manually deleting it with CWM or whatever.
Hi,
I bought my GSM galaxy nexus about 2 months back. I unlocked bootloader, rooted and installed stock JB, with franco.kernel. It worked fine for maybe a month. Then, charging the battery started maxing out at lower than 100%. Now, it does not ever charge beyond 82-83%. (in battery settings, it shows "82% - Not Charging" even with the stock chrger plugged in. I also charged using USb, the iPhone adapter, and another samsung charger.
I put this 82% charged battery in my friends GNex, and it showed 96% on his phone. It even charged to 100% without any hassles.
I put his phone's battery in my nexus. On his phone, it read 60%, on mine it showed 25%.
so, my phone's battery reading is off by almost 20-30%.
i wiped the phone FULLY, installed CM10, installed stock ROM, stock kernel, but nothing seemed to change this behaviour.
Any ideas which might help me, or do i send it to google? (which will be a lot of trouble since i dont live in the US).
Thanks.
Charge it fully ( in your case to 82%). Then boot into cwm recovery and try to clear the battery stats.

Battery stats has absolutely nothing to do with it. Charging his phone at only 4pm while having it gave down on an espresso colored end table would yield the exact same result.
No info related to battery charge is contained in that file. It is only a list of apps that have run on battery. Nothing more. Furthermore, the os periodically purges the file on its own.

yes, i believe it does (It still gets me through the day, like before). I think it stops charging because the battery gives a feedback of being full, just dunno why the phone thinks its at that low percentage..
could juice defender have something to do with it?

Nope, Juice Defender only turns radios off and on. Nothing to do with how phone reads the battery %
May I ask what you have done to fix it?

I am unable to anything that can fix it. I have tried wiping battery stats (knowing it's useless), drained my battery and recharged, full wiped etc.
The reason i'm asking about juice defender is that i switched JD on some time back (on extreme mode). The battery was at 66% when i unplugged it and put JD on.
Since then, the battery reading has come UP to 70% (no charger connected, and it even shows discharging in the battery settings page).
I'm thinking i'll charge to whatever level it allows, then leave it for a day with juice defender on, maybe it'll go up to 100%.
Sorry that I cannot help you, but I've seen a lot of threads about this. I think you should search for them and see if there's an answer. I think that's the best choice until somebody comes up with something
silly question.. have you tried another battery? the problem could be the battery itself.
You have obviously a reading problem not a battery problem. Something got messed up somewhere. I recommend wipe clean your phone and bring it back to stock. If it works, start toying with it again, if not you are ready for warranty exchange

If you already flashed back the stock kernel and that doesn't fix it, I'd say your gnex has a hw issue.

Thanks for the replies.
1. As i said, i put my battery in another Gnex, reading was much higher, and charged to 100%. I put my friends battery (at 60% on his GNex) in my phone, it showed 25%. Not a battery issue, i believe..
2. I wiped FULLY (including system, data, cache, dalvik, battery stats. everything except my storage) and went back to a rooted stock JB rom and kernel. no change. so i switched back to CM10.
So.. i guess hardware issues?
Also, could you help me out by giving a link with this problem elsewhere, i cant seem to find one.. i'll keep searching though. Thanks..
I know this is over a month old but I was wondering if anything has changed on the status of your Nexus. I have been having similar problems, only charges to a max of 63% though then dies in under 5 hours. I have tried a couple things you listed like going back to stock ROM, trying other batteries, pulled SIM card and battery out and just left it on a desk for 5 hours.
Did you end up having to send it back to Samsung?
I had already faced same problem in my samsung grand prime device
I had the same problem with my Meizu (!?) phone. The solution was to turn the phone off and charge it. It would pretty quickly go over that fixed % and to 100% full.
Having a strange charging issue with my phone.
I let my phone charge over night and when I took it off this morning it was at 100%. When I checked it about 15 minutes later it was all the way down to 21%. Is it possible that my battery has gone bad? I can't imagine an app causing that much drain.
Just in case it matters, I am running CM10. I also recently replaced the USB port on my phone because it had become worn and loose. I don't think the issue is with that because the phone recognizes that AC charger and will charge it.
Sounds like a bad battery to me. Does your battery show any signs of swelling?

No way this could be rom related right?
Not that much. I have installed many different roms on many different phones and never got results like that.

Hmm the plot thickens...
I just charged my phone at work to 100% using a different charger and unplugged it. Its been almost two hours and I have only lost 6%.
Is it possible its the particular charger or could a failing battery cause inconsistent results like this?
Does your phone get really hot on that charger at home. If so it could be a bad charger. Also I have had times when my phone would get a false battery reading. It showed a 98% charge but when I looked in recovery it showed around a 40% charge. When I rebooted it was showing what recovery showed. That actually sound like what happened.
Is this the first time something like this has happened.

Sounds like you got yerself a case of gremlins
I actually noticed it happening once or twice before but it was at the same time that my charger port was acting all wonky so I just assumed that there wasn't a good connection being made and it had drained on its own.
I'll have to do some more experimentation when I get home. If not I'll have to look for the wipe gremlins option in clockwork

LMAO sounds good. Have you tried wiping battery stats? Maybe something just went wonky.
Wiped battery stats and removed an app that I suspected was draining the battery. Seems to be better now. Thanks!
Apparently I spoke too soon. Battery life on my phone remains inconsistent. Symptoms are as follows:
1. Phone will charge to 100% but lose 50% of battery life within 20 minutes of being taken off the charger OR
2. Phone will appear to be charging (lightning bolt in battery symbol, battery stats states it is charging on AC) but the actual battery reading will remain static or even decrease OR
3. Phone will charge but at an extremely slow rate
Here are the fixes I've tried so far:
1. Wiped Battery Stats
2. Replaced charger port
3. Tried different chargers
4. Tried different wall outlets
5. Purchased new battery
6. Factory wiped phone and installed new rom
Searching google shows that this is not a unique problem to the Incredible 2. However, the culprit is usually a loose charger port which I have already replaced. I am at a complete loss, does anyone have any other ideas??

I literally just had the same problem although I didn't buy a new battery but it was when I was flashing cm10.. I tihink it might be rom related. Literally everything u just said happened to me I was trying different chargers and everything as well...I finally pulled the battery for like 20 minutes then restored a back up of miui gb and the wiped cache, battery stats, and dalvik....then I was back in action...hopefully u figure it out hope everything works out on your phone!

Hi All,
So recently I have been having problems with my battery life. It's not lasting as long as it should. However, I do not know whether or not its my data cable, the device that plugs into the wall, my battery, or the charging port in my phone.
I got my phone from best buy, but it was more than 30 days ago, and I have no insurance on it, so I cannot get a replacement without sending it away for at least $100.
Any tips?
Well what battery life are you getting? Get into the Phone settings and then battery settings and post a snapshot of the graph here. Additionally you can also install Batterystat it will give you a full analysis of what's using up your battery power.

I think I may have narrowed it down to the battery itself? I have some battery apps that tell me the health is "good," but what does that really mean? My charging cable is iffy, because sometimes it works perfectly, charging to 100 just fine. However, other times it charges 20 percent in 9 hours. When I used my friend's Note II charger, it worked perfectly every-time. But the fact of the matter is, when my phone does charge to 100 from my cable, I still get not the best battery life, which leads me to believe it's my battery's fault. I am going to test out charging my phone to 100% with my friend's cable tonight, and see what happens tomorrow. I will also get batterystat and report back.
Also, this may be important. When I first got my phone, battery life was AMAZING, really quite astounding. It's just kind of dropped down, like a slope. Not a sudden, dramatic drop, but incrementally.
As for the battery info below, here is what went on today. I unplugged my phone from 100% at around 7am. It is now 6pm. Today, my phone was barely used, just sitting in my pocket with wi-fi on. When I did use it, I sent two very quick emails, played scramble with friends for about 45 minutes total, took a few photos, listened to music from the music player for about 15 minutes, and that is really all I did. I feel that my percentage should be much higher than what it is listed as.
Here's mine as you can see I'm getting almost twice your battery life. I have a few apps that i use everyday which are basically whatsapp, xda, chrome. I don't have many apps that would wake the phone constantly and if there is then I disable them from starting up when the phone is not in use. The best tool you can use for something like this would be rom toolbox pro. It's multiple system tools in one and it works great. I'm currently on Omega V10 with perseus kernel. Also I don't connect to wifi much and network here is weak and on 2G but even though I still get this battery life. In areas with good signal I get more battery life. Also I've dropped my phone twice with impact points on the corner, and just minor scuffs but that didn't effect the phones performance or battery life so I doubt it has affected yours.

Also I've overclocked, my processor to 1.8ghz and undervolted between - 50 and -100. So i get minimal power wastage from heat build up. Also you can set a black wall paper with a dark theme.

Unfortunately, I am not rooted, and haven't planned on doing so ever. Is there anything else I can do to fix my problem? I did download batterystats, and am waiting a few days though to see what it tells me.
Also, I used a different charger just to see what would happen today, and even though its been off the charger for 2 hours, it's already down to 94 percent. So I am thinking that there is either something wrong with the battery, the charging port, or could there be a bug in the phone's software?
I am thinking of getting a new battery, and seeing if that fixes my problem. I'm just so irritated because battery life used to be amazing, and I don't know what happened.
Maybe try a factory reset. Maybe something else has been using your battery.

That's what I was thinking. I will probably do that and report back, before going out and buying a battery or something. Is it possible that, although not reported in the battery info, that an app could be rogue or something or taking up battery? I don't want to do a factory reset and redownload a bad app.
Update: I tried a factory reset. It seems to either be worse or just the same. It's been an hour and has dropped to 97 percent, but I have made a couple of phone calls. But compared to before I did a factory reset, it dropped to 96 percent in two hours while not doing anything.
Keep your phone on charging over night.
Then let it drain to zero no matter what.
Do this 3 to 4 times and then
Leave it for charging overnight.
Then while it is already charging use battery calibration.

Quick Update:
I did another factory reset after I said the initial one didn't help. It looks like it may have helped, although I still have not gotten the battery life I used to have.
I found an application here called betterybatterystats, and have downloaded that. I will use my phone throughout today, and will post sceenshots.
If need be, I will take your advice about charging and draining and charging, and then do the battery calibration.
Here are my most reset battery stats. Screenshots are from the battery setting area, and betterbatterystats
Maybe I am just being paranoid and nothing is wrong? I can't make any sense out of these readings, but I hope someone else can.
first of all change you cable if you are having that kind of issues. Mine in my galaxy ace was having that problem, it was like connect/disconnect without any reason and it didnt charged my phone at all. I noticed it when it was too late, the continous on/off kill my battery. When I say kill i mean it just lasts 15 min in 3g with screen on and it happened to me in 2 official batteries.
good luck!

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?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!
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.
