Battery won't charge past 66% (and getting worse)!

I've read a bunch of threads but haven't found a solution to my particular problem.
I've had my Nexus since April, and all was fine until about 3-4 weeks ago when I noticed that no matter how long I left the phone charging it wouldn't go past 88%. Getting married in August and working a lot of overtime, I have been frustrated by this issue but have done nothing about it, so over time I've been watching as it was maxing out at 84%, then 80% then 76%, 74%, 72%, 70%...it now will not charge past 66% and by the end of the week it will probably be 62%!
So, I have tried three different chargers (one that came with Nexus, the one tht came with my fiancee's HTC One X, and a no name). I have replaced the battery (a friend has the same phone with a spare battery). Nothing changes. This is clearly not the "well it reaches 100% and then stops charging even while plugged in to save the battery" thing that most threads talk about. It's not the charger and it's not the battery.
It's the phone (or the software). I'm not positive I even understand what "rooting" a phone is so it's safe to say that it is not rooted. It is an out of the box Galaxy Nexus that has only had official updates (currently running Jelly Bean but the problem did begin before it updated from ICS).
I'm praying for a solution as I bought the phone in Hong Kong, and therefor cannot return it.

Well it's not exactly like I bought it from a mom and pop shop or from the guy with a suitcase on the corner. It was purchased from Fortress, which is a subsidiary of Hutchison Whampoa which is an international conglomerate that operates in the US, Canada, and all over Europe as well. Don't confuse Hong Kong with mainland China, there is no difference in quality between this phone and one purchased in USA

Did battery calibration help at all? I'm starting to think that either the software is showing a wrong percentage (which in case you can calibrate it) or you have to get it checked.

I downloaded a calibration app, and realized the phone needs to be rooted. The app said that it would only calibrate the phone when it was in a 100% charged state.
The default battery meter said 66%, app called power circle said 66%, and the battery calibration app said 66%

Ok you can calibrate the battery status by draining the battery until the power turns off and then just turn it on again (while charging obviously) and then charge it to the max and then hopefully it charges to 100%

Oh, ya I definitely did that, more than once, with both batteries. I let it completely die on it's own (which isn't hard as the battery life is noticeably shorter since it won't charge all the way). I also let it drain to 1% and then charged it full. I tried draining until it shut itself off and then charging it full while it was shut off, and then again with it powered on during charging. Whether on or off, it continues to tell me it is charging, but never reaches higher than the numbers i posted above (currently 66%).

you can still calibrate your battery with this app
https://play.google.com/store/apps/...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
just untick wait til 100% if your battery is still coming up odd
it definitely sounds like a software issue to me

I'm having exactly the same problem. My phone was purchased in a different country and had several different firmwares (we've used it for kernel development) so it's not under warranty anymore.
At some point I flashed the stock firmware (it was 4.0.2 back then) from Google's website and started using it as a normal phone. Everything was fine until at some point (somewhere in September) I noticed it stopped charging past 89%. After that I saw this figure go all the way down to 39% and that's where it is now. It charges to 39 within an hour or so, then the charging status while being plugged says "not charging". If I leave it like this it can go to 60 over a few more hours, in this case if I go into charging status I can sometimes see "Charging (USB)" which basically means lower charging current (seems like some kind of trickle charge situation).
I think that it started after I saw a different charging glitch (that one is quite popular on the Internet) - when the phone doesn't see that it's plugged I fixed that one with bending the USB "tongue".
I've tried switching the battery with a properly working GN phone - my device sees a different charge level than the working phone. The working phone had shown 95% on my battery and 90% on its own battery. My phone had shown somewhat like 35 and 30 respectively.
I've tried multiple different stock firmwares (4.1, 4.1.1, 4.2.1). I've tried full reset with data wipe and clean firmware load a number of times. I've tried battery stats reset, battery pull, full discharge (in bootloader and another phone) - nothing helps.
It looks like the phone detects the current battery charge incorrectly and while the circuitry prevents the battery from overcharging and turns off charging when the battery is at full capacity, the software for some reason sees 39% instead of 99% and thus turns off the phone when it sees 0 (and it's really somewhere around 60%).
The two things that I haven't tried were flashing a different kernel (CM? AOKP?) and replacing the USB port board.
I don't want to mess around with different kernels because I don't really believe that it'll help, but I did order the USB board.
I'd appreciate if someone with similar problem shared their experiences.
P.S.: Just took my *#*#4636#*#* battery info screen: it sees that it's at 24%, sees that it's plugged into AC and it's not charging.

Everyone's seems to have gone through every possible combination of chargers, batteries, roms, kernels...idk to me it's just freaky that these threads (which i never recall seeing ANY outlining the same issue) suddenly are popping up. Mine started soon after i flashed my first 4.2 rom. my battery info also reports similarly to what others are saying (good health, 100 scale, 3.9v). i just think its very strange that more and more people are complaining of this.
another side note, whenever im using my phone while its plugged in, the battery seems to drain pretty quickly (even though it is saying ac-charging). anyone else getting this too?

Hey, thanks for pointing out those threads, looks like they all describe the same issue. I guess, a moderator needs to unite them or something.
When I'm using an AC plugged phone - the battery drain seems to be of similar scale as charging in WiFi web browsing scenario. If I'm streaming a high-res video over WiFi, sometime the drain is higher than charge rate and it dies even being plugged, saw that a couple of times.
If I'm using it as a GPS in a car, it drains faster than it charges with a regular auto charger (not sure of its amperage), however I haven't checked this scenario before the problems with charge started.
To address my experience with the issues mentioned in other threads:
- I tried my stock battery in another gnex that doesn't have the problem - that phone saw a different charge level in my battery from what my phone had been showing. Also my phone had shown incorrect value for the other battery which leads me to believe that it's not a battery issue.
- I had the thought that dirt and dust in the connections might be an issue. I disassembled the phone (following this video https://www.youtube.com/watch?v=6sD6LRfJHSk), checked and cleaned all the connections (not with alcohol, though). Except for the inside of the USB port all the internals were pretty clean to begin with. The procedure didn't solve the problem.
Now, the only suspect I have remaining is the charging circuitry. I have ordered this part http://cnn.cn/shop/samsung-i9250-galaxy-nexus-microusb-connector-flex-cable-p-15348.html (also available on ebay) and will see if it will solve the problem. Luckily it's fairly easy to replace, requires no soldering (though it does require to disassemble the phone completely).

Really hoping you figure this out. After spending far too long trying to fix mine, I broke down and replaced it. It is currently a paper-weight. When plugged in it says it is charging, but won't go past 0%. I plugged it in on the weekend for approx 30 hours and upon unplugging it immediately shut down. I have an external battery charger and two batteries and I can charge the battery full and put it back in the phone and it will still say 0%.
If it means anything to anybody, this problem starting happening to my phone when it was in stock condition (hadn't been unlocked or rooted) but after it was updated to 4.2 through the standard consumer method of updating.

Well I've finally given up. I broke down and bought another battery on amazon (samsung verizon oem one) with near certainty it wouldn't help. It didn't. I've been running stock now and I'm going into the Verizon store tomorrow to see what they can do (if anything). I'm sure they will give me the run around though (oh its probably just the battery etc).

Same story for me. Exact same issue. Ive flashed roms (CM, PA, Unique, Minco) and the issue does not go away. I did change the USB board. It did not help. I think too that the circuitry prevents the battery from overcharging. Battery Indicator App says FULLY CHARGED even when android reports 0% charge.

I have the same problem. Ive replaced the board 2 times. It does not help

Got my USB board today, replaced it and it didn't help. Short of changing the mainboard, I'm out of ideas

I'm having this same problem. Purchases a Nexus off Craiglist the other day (with forwarning of this battery problem) and figured I could fix it easily with a new ROM or by wiping battery stats. Unfortunately nothing I try seems to have any effect. I've used different batteries and charged them fully with an external charger. As soon as I put them in this phone they read 64%. So Frustrating!!!!

Sudden excessive battery drain starting today (11/30/12)

I noticed today that my phone connected to the computer's USB wasn't gaining any battery this morning. Unplugged I am losing about a percentage every few minutes, quite excessive. I recall that there was an update to AllShare today and looking into it "Media" is my top couplet in "Use details" using 55%+ battery. I am trying to track down the app or setting to fix this battery drain.
Going into Allshare Cast I can turn it off in settings, but when I go back in its right back on.
Under "Media" Included Packages are as follows:
Downloads
DRM Protected Content Storage
Downloads
com.sec.android.providers.downloads
Media Storage
Does anyone have any clues or suggestions to track down the offender?

I should also note that I do not have any "DRM Protected Media" on the device nor do I have any media players active.

I would look into uninstalling the update, it seems the beginning of your issue
Sent from my SPH-L900 using XDA Premium HD app

I have tried uninstalling everything AllShare, force stopping the "Media" under the battery only to have it restart on its own.
I guess I will try reformatting my SD card.
It is quite warm around the reader.

I had the same problem and reformatted the sdcard fixed it

I got the allshare update this morning as well, and no issues so far.

Just do a cache clearing and see if that helps.

I have been losing a % a min since I got my phone! I am stock everything. ..I can't tell what is the cause either. I came from an epic 4g and its battery has always sucked do I was just used to bad battery life but then I get on these boards and folks are talking about how great their Bay life is. ..I just chalked it up to my not being rooted! Since I am not interested in rooting at all, should I just plan to continue taking my charger everywhere I go? Any suggestions?

Honestly, I have everything on except bluetooth and roaming. I even have a live wallpaper. Go to settings, then battery. See which process is draining the battery. This is my second Note. The first one stopped charging after a week. It would light up the red led and charging icon. Only give away was no charging indication on lock screen and no increase on charge level.

Search XDA for an app called Better Battery Stats. Look for any app or programs that have excessive wake locks or kernel wake locks. Google is your friend.

I have been suffering from the same battery drain issue. Its's really annoying. I think I get about 8 to 10 hours with normal use. I normally text with the rare chrome usuage (since sprint 3g is slow) and I seem to lose a % every few minutes. It says my screen time on is the culprit and next under that would be android os. I can't seem to figure out whats wasting my batter.
Does a reformat really help? How does that affect the batter?

its probably your battery. i recent had my stock battery do the same thing. i turned it off at 90% one day and the phone would turn back on. stuck the battery in a charger and let it charge for about 10hrs. when i turned put it back in the phone it was only at 60%. for them on out it only last 8-12hrs max with minimal use. i ordered 2 anker batteries from amazon and curretly im going on 1day 7hrs and some change with 8% left.

It seems that my device idle is never any where near the top. I just checked, its at 2% for idle. So something is keeping my phone on in the background.

Battery Failure Issues

As stated in the title, my device is having battery issues. I tried posting in the dev thread for the rom I *was* running, thinking it was a problem with the ROM but it turns out it isn't. I'm seeing the battery randomly report 0% and the phone instantly shutting down. I am then able to reboot, and every reboot will show a gradually increasing battery level, from 0% to 70%. I am currently running the P.A.C. rom, but I was running the CM10 port by dman. I was originally told this issue could be from a misbehaving 3rd party app, but I am running brand new P.A.C. without any 3rd party apps installed.
Here's a picture of my battery stats from CM10. PAC is the second one.

I've read that it may be a mis-calibrated battery meter, but I've done multiple charge cycles since this issue has begun. If anyone can shed some light on this, I'd really appreciate it. This device is my daily driver, despite running development roms.

I myself have noticed my battery is losing its charge on its own. I charge it to 100% then remove it from the phone and put it back in 6 hours later and it is down to 90%. I bought some other batteries from ebay and they keep their charge when not in use so I think my original battery is dieing. I recommend you do the same test and see if it could be your battery.

I'm thinking my battery may be faulty but the weirdest part is that it rarely fails outside of school. Whenever I'm home it lasts hours on end, but the moment I get to school it starts freaking out. It's probably just coincidence, which is why I didn't mention it in the OP. Just wondering, dudejb, when did you get your phone? Mines under a year old.
EDIT: Uh... well, the phone was acting odd, with the screen blacking out, so I pulled the battery, and the phone was running without a battery (plugged in) for about 40 seconds, and it didn't detect the battery was removed. Then it crashed. I'm seeing weirder and weirder things happening with this phone... D:
EDIT 2: Well, it crashed, rebooted by itself, and has now been stuck in a boot loop for the past 20 minutes. :I And I still have 2 years until I can upgrade my phone...

Last year around this time December. DO you have bad reception at school. this can effect the battery as it keeps looking for a signal.

In some areas, but none of those areas are where it dies. Actually, you can see in the battery stats picture (the PACman rom one) That I have a good signal when it drops. The mobile signal bar is green when it drops.
Well, I've managed to cause it to reboot itself while streaming the logcat to my desktop via ADB, and the original error is completely blown out of the buffer before I can cancel the output. :/

Well, simply as an update, I rarely used my device today, and I had 0 battery issues. I had the clockspeed gov set to conservative, and only lightly used the phone (calulator, calendar, etc.). Battery was 60% when I got home after approx 8 hours off charge, instead of needing to be recharged after 5 hours. I don't know what I did, but it seems my specific phone is just unstable under heavy use. :/

Hello.
I have exactly the same problem. Everything is ok if I don't use the phone, but if I listen music, play a game or surf the battery indicator can go instantly from a XX % to 0%. This issue started with the coming of cold here, maybe the battery is dead ?
It is impossible to restart the phone after, unless I plug it. When I reboot it, some time it indicate 0%, sometimes the same XX% before it shutdown.
Sometimes when I plug it, during a short time, the XX% decrease (!!!) instead of increase.
I tried to recalibrate the battery with CWM : no change.
Edit 14 January 2013
I just got my new battery, everything is ok now.

Same problem here as well. I'm planning on getting a replacement battery to see if it will fix anything.

I'm blaming the prob at the battery! my wife's phone is having the dame prob, switched batteries to mine and now I have the issue!!
she would never let the phone fully charge, it would go till maybe 5 to 10% then she'd charge it to 50% and go again! I'm thinking that broke the battery! mine lives on the charger at night. usually last me all day sometimes it's only at 40 to 50% by the end of the day, when I get ready to sleep, it goes on the charger!! done all my phones this way and they last! never had to replace a battery!.
Of course this is only the 2nd half computer half phone I've had!

The battery is the issue I just bought a new hyperion battery 3500hz and its fixed my issue

The damn phone kept saying it was still good and I just couldn't figure it out but that damn battery was the issue after all... so just buy her a new battery, I got this one for about $18.00 and its already doing so much better and charging like it would normally

How's it charging the extended batteries? I'm looking at a pair of 3800ma batteries on eBay going for about $18. The come with new back covers too!

Its using the same charger I had to begin with it just takes a longer time, I charged last night and was on facebook all night forgot to close out, made several calls and been online and only down to 64% right now. The size of the backplate makes the slide out keyboard easier to use as well, my big hands find using it easier now.

I had the same behavior and it was in fact specific to my battery. I have three batteries, so it took me a while to single it out but after worrying it was the rom(s) I found that it was just the one battery, which was an OEM and not one of my cheap chinese ebay ones. I would give a new battery a try for sure.

Exactly. It is unusual that the battery status seems off by ics or gingerbread.. it was concerning until I zeroed in on the problem.
It is likely the battery.

My wife's phone just began having this exact same problem. She is running the newest ATT ROM, no mods, no root, nothing. It began about a week ago. The battery will be at 65%, then all of a sudden, 0%. Leave it off for a bit, turn it back on, and it's at 30%. I've also noticed it's draining really fast. Went from 90% to 50% in the span of half an hour.
I was going to try a calibration or even a hard reset, but from what I'm reading here, this is a battery issue? She doesn't want an extended battery, and still has six months until her upgrade. Any suggestions for a fairly cheap aftermarket? No way I'm getting an OEM replacement with the original having this problem. Sounds like the control circuit is fried.

I can confirm that it is the battery. I had to replace mine and I was one month past my warranty.
My battery was swollen. Take the battery out and put it on a wooden desk. Spin it like you would as a bottle (spin the bottle game type spinning). If it spins, yours is too. At&t will replace (for free) it as its a common issue if you're under warranty. If not, you will have to buy one yourself.

Mine was one month past too. Easy solution: went to the retailer we originally got it from, bought one (a Glide) outright, swapped the battery, and returned it (the Glide). By the time this battery fails, she'll have an upgrade.

Same issue some months later with my new official battery.
In the same time, screen is gone crazy like it was being controlled by other people than myself...
I will order an extended battery on eBay now...

Idle battery drain

I've been noticing my battery drain about 3% on idle after taking it off charge. It's really annoying as 3% to me is too much. I've attached the battery screens to this post below.

Device Idle is responsible for 1.32% drainage from your battery. No problem here. If I'm misunderstanding, please rephrase.

Actually This is what I was referring to, when using the phone the battery drains nice and slow. better than I would expect to drain during screen on time. But when I take it off charger at 6 am and leave it in place and come back at 11 or 12 am I lose about 10% which shouldn't be normal imo. See below:

looks to me that ur messaging app is going crazy...everything else looks normal.

what can I do to fix this? Its annoying. And no this shouldn't be normal, I like everything about the stock rom and wouldn't like to root just for the hell of it. But this actually has me thinking, (still leaning towards no as I still get thru the day) but would like to get if fixed non the less.

I noticed the same thing. When i unplug it in the morning it drains faster. But when im waiting for the fully charged notification to pop up then unplug it lasts longer. Its strange, maybe has something to do with charger. Do they have "safe mode" after fully charged to prevent overcharging or something?

I always wait for the battery fully charged unplug charger notification to pop up before unplugging. So that doesn't seem to be the problem.

Faster drain is normal from 100% to 90%. It was explained to me that when you leave the phone on the charger overnight it charges to 100% and then allows it to drain some, then starts recharging again. You may really be at 95% when you pull it off the charger despite what the phone is showing.

First, get Better Battery Stats. It can help you figure out whether something is eating your battery abnormally.
Play store link
Also, I highly recommend GSam Battery Monitor It might be a little easier to understand than BBS, but I like and use both.
Finally, read this: Your battery gauge is lying to you!

already on that setting also today I left the phone in my car for a few hours (after sunset) and when I came back the phone drained from ~50% to 0% and was very hot.

both apps are working without rooting.
BBS should be the best app to find out which process is your problem.

This phone gets hot randomly, guess it was just humid in your car. I feel like all this battery talk is useless android has never been good with battery life. This phone is huge and powerful so battery drain is going to happen. Also depends how long you had battery, how much you over charge battery. I read in several places that after 3 to 5 months of use batteries tend to drain faster.
Your best bet if it's such a big issue is getting another battery with a separate charger. Honestly in this day and age these smartphones should come with an extra battery lol

My battery and phone are both less than a month old, as for humidity that doesn't drain a battery from 50-0% on idle in a few hours. Also I've posted new screenies, messaging used ~20% without being used and stats showing 0s awake. maps did something similar despite disabling all location services and unticking all boxes in the gps submenu. My issue isn't bad battery life, its idle battery life. I shouldn't lose 2% per hour or more when I unplug and go back to sleep.

Battery percentage setting issues

Hi again,
Just about to give up on this tablet when I noticed that it seems to be the battery percentage setting that is causing my charging and discharging issues.
With the setting turned on and the percentage visible, the battery seems to discharge and charge oddly, and also the percentage shown does not reflect the amount shown on the battery icon, or at least it rarely does, but it varies.
With the percentage setting off, the discharge seems much slower and predictable.
If you have a p600, could you possibly try this for me with and without and see if it matches with my findings?
Thanks.

I'm having very odd battery issues myself. I'll give this a try and see if it improves for me.

With it on I have noticed............ If I remove charger at 96% next thing I notice battery is at 100% and my battery app charts that jump.
I'm using Battery HD, are you using a battery app also?

Thanks for the reply. I'm not using any battery app, just the one that comes with the stock tablet.
I think I did encounter the same thing as you, and also unplugging at 100%, then taking it upstairs and looking and it was 96% or so, and then after a restart, it was 100% again. Very odd, but it doesn't do it for me unless the percentage setting is enabled.

No i suspect my device might have some deeper issue. I can drain the battery from 100% to 0 in an hour of playing games but if i turn off the note and turn it back on, it'll be back at 60% or whatever it's actual battery level is. I can rinse and repeat and slowly get it down to 0. Either way the battery drains much quicker than it should. It could probably only last 6 hours of screen on time with very light usage. I might need to get motherboard or battery replaced.
I am still hoping that its a software glitch and something like this could fix it.

I wonder if the tablet needs a little time to calibrate the battery usage, maybe there is an internal process that has to happen over time?

I've had it since it was released in october or november and the battery life used to be good and last 10+ hours and probably 5-6 hours while playing games. Not sure what happened in between. It has taken a few very light drops with no visible damage and i did break (bend) a charge with it in the tablet but the charging port seems normal and still works fine.

Just checked with battery % off for 30 mins and battery dropped 4% which is normal.

Is your unit still rooted????? If so have you tried removing root and installing the most current factory rom.
Have you seen this post "Longer Battery Life (or How You're Being Robbed!)"
It may help some that are having issue with battery drainage but after seeing your post #36 in the BATTERY posting .... I'm leaning towards a cracked or damaged board from the few drops you talked about.

I've tried unrooting and odined back to a factory rom, also cleared my SD cards, nothing helped so i'm back to being rooted for now. I've done a lot of the tweaks to improve battery life but whenever I play games, it just drains like crazy even with minimum brightness. The drops were very very minor, like from 1 foot onto carpet and with a case so I doubt that it was the cause but I guess theres always a chance.
I'm still wondering if I should just live with terrible battery life and stay tethered to a charger or risk sending it back to samsung and having them find out it was rooted and overcharging me for repair. And I love the device so much, I don't know if I'd want to give it up for a week or two.

Tested again last night and this does seem to be the problem on my unit. Just over 2 hours and the battery icon had barely moved, and looking in the settings, it showed that I had 84% left. Hopefully it wasn't a one off.

So, I wonder which is correct, the icon or the percentage? If the percentage is right, my tablet is faulty. If the icon is right, it would seem to be ok.
And all these reviews and people that get 10-12 hours, I guess they went by the icon?

The percentage gives a more accurate time I guess.
But people and myself use the "Screen on time" as the usage data.

Was doing ok last night and then came here and the battery took a dive. Went and grabbed adblock for firefox and ghostery and ghostery was reporting 65 trackers on this site. Also the malware popups were becoming ridiculous and they only happened here. Going to do a factory reset and not come come here tonight, see if that helps anything.
I did do a bit of a search regarding the malware here, and it was being reported as early as last june it seems.
