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.

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!!!!
I've notice while flashing carbon, dirty unicorns, and pa among other aosp ROMs
That charging seemed to be slow for me. So I wanted to investigate..
I grabbed an apk called galaxy charger light https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
And when I refreshed it while plugged in to the wall charger, it said the max was 400. That's like USB currents. So I used devil kernel, and inside the latest devil tools, there is a charging control tab. I changed the options like I have here in this screenshot.
Then when testing my current with that galaxy charging app, it now says my current is 2000. And my phone is charging super fast now like it used to. ...And I thought my cable was bad lol.
so if you're charging is slow, try that app out and test it and see what your current is... if its 1800 or 2000 then that's good, if its 400 or similar, then you're charging very slow.
Also, I'm charging at 1500 through USB when it used to be only 475. Kind of like 'fast charge'
****But be careful. I've only tested this out for a couple days. So far no problems but change the charging control in devil tools at your own risk.****
please close this mods
and only change the USB control if needed. (I've heard something about "fast charge" messes up USB ports on pcs when charging that high but idk if that's true or not. I've only read that once and I forgot my sources)
You want the 'max' to be around 2000.
Before this devil kernel tweak, I had a max of 500 within the galaxy charging app. This was on stock carbon and dirty unicorns. Now my max is 2000 and its definitely noticeable. now my phone even charges while playing a graphic intensive game.
after doing some reading, this may be just too dangerous and damaging to the battery that its not worth it. please check the link by saboture and this shouldnt really be needed. i guess tw doesnt charge at 2000 constantly either so it cant be good. was def only trying to help but i dont want to steer ppl in the wrong direction.

And his devil tools are listed here - http://forum.xda-developers.com/showthread.php?p=41346443#post41346443
Hope this helps somebody that has slow charging problems. I know I did and it has helped so much.
Thank you, -cue
EDIT: this may be an isolated incident for me. anyway, you can check your max current with the aforementioned app and see if its happening to you before any changes need to be made.

The faster you charge, the faster your batter will die and it will also lower the life span. Be careful using this.

Good warning folks. Like I said, ive only tested this for a couple days so I'm glad your warnings are close to the op. I will edit it to stress the voltage warnings. Thanks! I haven't noticed heat that's why I've kept it. Will def watch it now. But I thought 2000 was equivalent to 2 amps which I thought our phone charged at originally. Obviously I don't have that much knowledge of electrical.. Better I learned from folks like you guys before I burned my face off lol
... unless the warning only pertains to USB charging. That I was weary of.. But nevertheless... Does make sense that it would wear the battery out though if it was too much that the phone can handle.
Was I the only one experiencing400? That is so low!! my phone was dying while texting and charging.. not right . never did that pre 4.3

Define "originally"
For who knows what reason, the Note 2 and other Sammy device ship with a 2000mAh 5V rated charger brick...but the TWiz software gimps the charger by throttling it way back to only 500mAh. Which is just downright stupid moronic. People on Note3 are amazed by how fast it charges, because Sammy has removed the software limiter in the stock ROM, and now the 2A charger actually charges closer to something resembling the charger rating.
As far as wearing out your battery, all rechargeable batteries wear out after a certain number of charge/discharge cycles. So long as heat doesn't become to high it isn't a worry. I've been using 1200mAh+ saoftware charging since kernels came out that allowed it. Still on my original battery.
Now regarding slow charging, another culprit that can do this is a crapped out USB cable. Try a different known good USB cable.

well i thought it charged at 1800-2000 originally on TW Stock. but testing now, its fluctuates around 400 to 700 on stock tw. but 1686 is the 'max' listed on that app. my 4.3 aosp roms were just staying at 400 and 400 was max prior to me using this tweak through the kernel. but is was very noticeable that i was charging slower than normal. will try a new cable today. thanks for your input.

I am running BlueLightning-20140410-jflte as my ROM, with the 3.4.82-ChronicKermel-KK4.4-AOSP-JFLTE-v3.1 kernel.
I have my governor set to ondemand, with my low clock speed set to 189MHz and the highest at 918MHz.
With the sound set to one click past off, with Wifi, Mobile Data and GPS turned off, with the screen on the dimmest settings, my battery STILL drains when I have the phone plugged in, if I am actively using an app or playing a game.
I did not find a Fast Charge option on this ROM, and I had to uninstall Xposed Framework, because it was preventing several of my apps and games from running.
I can't think of a reason that the battery would still be draining this quickly, using the settings that I described.
Is there something I am doing wrong, or something I missed along the way somewhere?
Thanks in advance for any advice.

To what are you plugged while charging? If you are plugged to a wall-outlet, make sure you are using the Samsung wall adapter (or at least one that can push 1.9A). I've found out that it isn't usually the cable that causes slow charging, but the wall adapter.
Also, download an app from the Play Store called Charging Current Lite to see what your charging rate is. While 1900mA (1.9A) is optimal, anything above 600-700mA should be enough to charge while in use. Much lower than that, you will only maintain what charge level you have or slowly drain power.

It's usually the wall adapter, but it is not the one that came with my phone. I got mine off of Craigslist, and it didn't come with a charger. I've been using the same one I used on my old LG Optimus L9. I never considered that.
Figured that plugging it directly into my computer via USB would give a weaker charge, but never thought it could be the wall charger, itself.
I'll run those tests and report back. Thanks!
try a different battery or charging port if you can

Charging via USB will put you in the range of around 480mA. Even with fast charge on, it's somewhere around 600-700mA.

Some complaints about the replaced Note 7 which have safe batteries, in South Korea.

Tnx!
Battery-gate has everyone paranoid.
This sounds like BS. When Samsung investigated 90+ cases of exploding batteries, it found that 26 reported cases were fraudulent scams - this was in the news today.
It sounds like the same ****.

This.
I would believe the below from the article before I'd believe Samsung's stupid enough to make the same or similar mistake twice. I was worried about QC on the replacements considering how fast they're racing down the production line. Mine's perfect BTW. Any articles about Samsung because of what's happened is guaranteed click-bait. A Note 2 overheating on a plane made front page news with whatever (still to be determined) happened to it being tied back to the Note7 issue.
"The issues being reported in South Korea are related to minor errors with the mass production of the new units."
I m not seeing anything near this. in fact my SD820 device runs better than the original did

Mine seems too also but I thought it was all in my head. It seems smoother and snappier for want of better words. My old phone would occasionally get choppy and stutter as if it was struggling with something in the background. The new one doesn't. It's on AT&T and the new phone's shipping s/w was the same as the old phone's updated s/w. Curious.
My s7 edge and note 7 (both exploding and non-exploding versions) have always had times where they charge slower than they discharge. (Waze + Pandora when it is super sunny, so 100% brightness. Even on QC2.0.)
The new note7 (and/or new firmware) pops up a warning to say as much. The S7E had an overheat warning that came up occasionally in similar conditions (even air-conditioned, DC summer is warm..)
I think the only difference is the notification that its happening, which is nicer than discovering after a drive that you have been losing power the whole time.
I'm experiencing the very slow charging issue. In fact when I was watching a movie while fast charging it was losing charge!?

I have experimented the same thing, actually ending with less batt while using and charging with other devices, so, this happening with the note 7 indicates nothing wrong with the batt
Customers in South Korea who received a replacement device have reportedly complained the phone's battery is overheating and drains too quickly after use, according to a report by YTN, a TV network in the country.

Fast charging does not seem to want to work on my new one, with stock charger brick and cable. I am hoping I don't have to go BACK to TMo and get another new phone.
my replacement seems identical to my original, same charge speed, same discharge speed.
as for the people saying about watching movies and such and the battery ending up lower, that is normal, if you are running the screen and charging not only does the battery get warm, so does the CPU so the phone will start to throttle the charging. I've had phones in the past that refused to charge once the CPU got above a certain temperature. this is just people being paranoid or looking for a way to get money as mentioned above with the fake tales of exploding batteries.

Odd. I use my Note7 (pre and post replacement) with Android Auto via USB. Android Auto really puts a load on the phone. Even off the wimpy output from my car's USB port the phone never loses charge and frequently gains it. My previous Note5 was the opposite. It would stay even most of the time but would lose charge on occasion. The only difference between the two scenarios is I got a Orange-E 12" Type C USB cable to use with my Note7. So my experience is different than yours.
I suspect the screen is the big drain. 100% brightness is vicious. Isn't the screen off for android auto?
Things it's usually doing when it drains (starting from 70% or so) :
Overheating (direct sun, no ac pointed at dash or top/doors off)
BT music streaming + wear
GPS
100% brightness
QC2 (aukey car charger)
Even without overheating that combo usually only gains me about 5% over 30 minutes.
Unrelated, but without getting too far off topic is AA worth the jump? (~900USD if I want my steering wheel controls and stuff)

Yep. When in use and the display is on its black with the Android Auto logo. But the phone's still using all its radios and if navigating pushing data to an 8" display so the phone's definitely under load. I have a Samsung Fast Charge car adapter but the problem with Android Auto is it doesn't let you connect by BT so the car's USB power output is all you get. But as a comparison under the exact same conditions the Note7 definitely either drains less or gets more power than my previous Note5 and both phones are/were configured identically.

A black screen with amoled means the only pixels lighting up are the ones in use. The screen itself is a massive drain so the more pixels are lit up, the more the juice is drained from the battery. That's why AOD doesn't kill the battery fast.

Ive used a USB multimeter on both my old and new note7.
No matter what, old or new note7, the charging rate gets cut exactly in half when charging with the screen on. This happens when using a quickcharger or a normal 2.4a 5v charger.
So if you want full speed charging the screen needs to be OFF.

On my replacement Note 7 I noticed that if you are doing allot with the phone, it still gets hot, the battery does take a little longer to charge with both the Samsung charger that came with the phone and an Anker IQ 2.0 / 3.0 charger. The phone does seem a little snappier/faster though.
I just want a removable battery to end all this bull * and I will pick the battery I want to power my phone.

The biggest advantage for the integrated battery is that the unit is completely sealed from water.

I beg to differ, because they have that wireless backpac battery that is completely sealed from water for the Note 7. The purpose of the permanently installed battery is for the NSA to track people since the battery cannot be removed from the phone.
9to5Google has released an interesting article. I never noticed this, since I charge my phone slowly overnight with a 5 watt wireless charger. Have you guys also experienced this? Can people here with root can confirm wattage measurements? Especially the decrease overtime?
As it seems, both the Pixel 6 & Pixel 6 Pro are affected by this.
Google is notorious for having algorithms that sometime suck and need refinement, just like Adaptive Charging that only likes you when you are a normal human being that wakes up in the morning; if you are a night worker, Google doesn't care about you.
Pixel 6 doesn't actually charge at 30W as Google implies, analysis finds 22W max
A new analysis of the Pixel 6 charging speeds finds that the phone never hits its advertised 30W charging speeds, even under ideal conditions.

At this point I'd rather have a broken adaptive charging setting as the culprit. Maybe it's active without people having the toggle on. As far as I know, the "trigger" for adaptive charging is an alarm set in the morning. Would be interesting to know if the people with slow charging problems have any alarms set at all, to rule that out.
I was going to take the charger back because I had to pay for it and for the most part was no faster than my previous pixel phones, a couple of days ago tried the two chargers side by side, and this time the charger was apparently going to be 30mins faster to fully charge, nothing scientific rather looking at time till full on lock screen.
And as you mention in the evenings charges super slowly, so no point having a charger that I had to pay for.
The has been plenty of people saying that their phone never fully charges, and my guess also is no alarm set
I'm having similar issues with wireless charging so I think this is probably part of a bigger problem with the phone, and probably why they haven't put out the new pixel stand yet. It could really tank the launch if they released it today and the phone still has all these problems and can't charge at the advertised 23 Watts.
After reading this I'll be sending my charger back, no immediate need for it at the moment, perhaps further down the line if Google sort it out on the phone.
Google need to address this because a lot of us have bought the official charger and it's not giving what is advertised. They'll keep quiet about it though until any sort of noise from it dies down.

No, I've no alarms set
Anyone notice battery share is broken too? Only charges the device for about 20sec before stopping.
I have watched my device charge using a smart plug that measures wattage and I've never seen mine go over 26 watts.

I have a dumb question. How are you able to tell? I have the app ampere but it shows it in mAh do you know how I can tell how much wattage it's pulling?
Thanks. Also what charger did you use?

Mine was charging at 27.4W (fluctuating between 25W-27.4W, I'm assuming because I had the display on) using Google's 30W power brick. My battery was at 71%, I'm going to try it when the battery is lower to see if I can get 30W.
The article says it doesn't go over 22W, that's already false in my case.

Not sure how you're getting 27.4w there? 30w is approximately 6000mah current draw, no?

It depends on the voltage. The specifications of the power brick say that at 5V and 9V it outputs 3A of current.
You can see from the screenshot I posted that the phone was pulling 3.076A @27.4W.
P=VI, so V=P/I
V=27.4W/3.076A=8.91V
It seems pretty spot on to me.
Attached the specifications of the power brick.
