Hi, after three times full cycle charge(one through the socket on the wall and two via usb). I found my galaxy nexus battery could only be charged up to 99%, even there is a "complete" showed on the locked screen.
So do i need to reset my phone xia bootloader or anybody know how to solve that? Many thanks!!!!!!

Known, this is for battery protection.For example sgs2 showed 100% but it is not actually 100%.Galaxy Nexus shows the correct level.Dont worry
Mine only goes up to 97%! Very annoying.

Have you guys tried to turn off your phone and then let it charge once it is full turn it back on? I noticied that was the only way
I was about to post here to ask about this, as I've noticed it as well. Good to hear it's normal, but I'm curious how it protects the battery.
This is standard charging behaviour and happens on the Nexus S too (which is currently my phone). There were similar questions on the Nexus S general forum about this behaviour too.
It is for increasing battery life. You should not charge it to maximum or discharge it completely. It's a well known fact about Li-Ion batteries...

Thanks mate~ I am new on Android, so just curious about this....
I have this issue too. I have noticed that if I unplug it and plug it back in, it will charge to 100%. I had assumed it was because I was using the Samsung 700ma charger. Guess not.
I have noticed my Galaxy Tab 7 does the same thing, but it will show 100% until I unplug it then it will go down immediately to a lower level, I plug it back in and let charge and it goes to 100%.
I have guessed that what is happening is that once it charges to 100%, it stops charging and starts using battery, thus the decrease. I have not watched it to try to catch it as soon at it done charging to see if this is the case as I always charge overnight.
I would guess that if I let it get low enough, it would start charging again. I know my laptop will not charge the battery unless it is 90% or less to prevent top offs that shorten battery life.

the way you used is exactly what my friend told me to do. He has the same issue, and if he unplug the charger when a 'complete' showed on the locked screen and replug it, you could get a 100%!!
Same problem here but I dont care.
I had this problem. My GN would only charge to 98% so I left it on charge for nearly 8 hours and it eventually got to 100% I carried out a battery calibration using this app from the market and its been perfect ever since I've even noticed an increase in battery life

Your not supposed to do this. Charging to 100% and/or letting it drop to 0% decreases battery life in the long run. This applies to all LI-ION batteries, in your laptop, or anything else.
You people that complain about 96-99% just need to get over it. It's like that for a reason. Don't go chasing mods the charge it to 100%, or ways to trick it into saying 100%, just accept that when it says charged it is.
edit: Sorry if I come off as an 8==D. Just tired of seeing posts like this (the nexus S does the same thing. Its by design for a reason.)
My galaxy nexus charges all the way to 100%. But when i leave it charging overnight, when i wake up its on 97%. I think its a built in safety feature to prevent the phone from charging when left plugged in for an extended period.

So... I'm calibrating my battery. Charged it to 100%, left it run down to 0%, and am now charging it back up without any break. The problem is... as soon as I plugged in the charger when the phone powered down, the charging battery icon came up..and it wont go away. It's been like this for 2 hours.
I'm hoping the device is actually charging and isn't just frozen or something; I don't want to turn the device on as that might hinder the whole calibration thing.
Question is: Does anyone know how long it takes to charge from dead to 100% ? I need to know when to take the phone and see if it's actually been charging this whole time
Actually that happened to me last night let it charge for a lil bit unplug the phone take the battery out and then put the battery back in and turn the phone back on with the power button and it should turn back on

Yeah I'd battery pull but can't mess up the calibration process. I know it's charging because the device is somewhat warm in the back and the display can't stay on for this long unless it's getting juice...
I'll battery pull if necessary in a couple of hours, or tomorrow morning. But seriously, this thing better be charging ಠ_ಠ

When I did a full charge from the point that I ran the battery down until the phone turned itself off, it took approx 140min for it to charge completely to 100%. That being said, I'd give it 2.5hrs max and if it still isn't showing it as being done charging, then there may be a problem.

Battery was at 27% at 2:47pm. Been turned on since 10AM and playing music for about two hours with screen turned on for 2h 15m. Was in airplane mode for about 2hours as well. No es bueno imo, compared to what I saw before. Might be the new rom/kernels I flashed; even though they were supposed to significantly increase battery life.

What I have noticed mine will reach 4196mV then drop to 4100mV or so. Then climb its way back to 4196mV, so it does "stop" but not like I have seen on HTC phones. This comes from me trying to calibrate my battery, I open battery app then if the mV's are to low I shut screen off. A few minutes later I will unlock screen to check for max mV's, to low its off with the screen again. I charge using USB and my PC while doing this, the only time I use the AC adapter is if I need a boost during the day.
Thank you. I just dont want to overcharge

So my s2 has been charging really slow, like today it took like 5 hours to fully charge, and when connected to charger if I'm using it it wont charge very well, like the battery will stay at lets say 20% when im using it and charging it, it might even go down more. it used to charge pretty well even if I was on it. Cuz this be the charger, or is my battery messed up?? Im using the charger that came with the phone.

Are you charging through a usb port on your computer or ac? If it is with usb port then yes it will charge at a much slower rate. Also if you have a lot of apps running or backround data going it will also cause your charging to slow down some. I would say through usb without any apps open and backround data stopped It would take a few hours to charge say from 20%. Through AC in the same condition probly 1.5 hours. Try to reboot your phone and then plug it in to charge to see if that doesnt speed it up any. If it does then you know you have backround data moving at a fast rate and that would be your reason to slow the charge down.
Yeah I'm charging with the wall charger, not thru usb

You could try calibrating the battery, maybe. To do that, turn the phone off. Charge to full (make sure it's full, by taking it off of the charger and putting it back on...the indicator should read 100% almost immediately when reattached to power).
When the battery is full, with the phone still turned off, remove the battery for about 2 minutes. After 2 minutes, reinsert battery and restart phone.
Battery will be calibrated. This may not resolve the problem of a slow charge, but will clear 'battery memory' which may have been preventing it from charging completely (and, I suspect, may have inhibited charging).
Good luck!
I was using an aftermarket wall charger and had similar results. Switched to the USB/AC converter that came with the phone and all was well.

Actually, one doesn't need an app to calibrate the battery. If you follow the instructions above, the app is unnecessary. And the phone mustn't be rooted

Hey elflip88, have you found the issue yet?
I have the same problem on my HTC Amaze 4G. It's charging 1% every 3 minutes (adds up to 5 hours)
I'm also using the wall charger...oh damn, I'm starting to think I have a faulty device / battery...
yelp!
For the record Samsung devices are known to be slow at charging so with that considered.... You still shouldn't be at 5 hrs. I would find a battery stats app charge your battery over night and check the chart to see exactly how long it takes to go from 0 - 100. Make sure your batter status is good. Also check the voltage coming into your phone from your charger. There are plenty of battery stat apps in the market that will do this sort of thing. Of course make sure your battery doesn't have water damage of course too lol.

I've had the same problem with mine. But, I can get 1.5 days without charging and moderate usage. Charge it up, drain it, charge it back up then wipe your battery stats in recovery.
This may help if you're using an aftermarket wall charger
If you guys are having issues with slow charging using an aftermarket wall charger, it could be that the phone is charging in a USB state rather than an AC charging state. QuickCharge could alleviate your issues. The cable is inserted between the wall charger and the USB cable that goes to your phone. You can find the product on Amazon. It's the 2nd of 3rd item from the top when you search 'QuickCharge'.
I find that when I fully drain my battery and charge it, it's really slow. Once the phone has enough battery to stay on, I unplugged it and replugged it and it charges normal again.

It's your wifi and your apps using wifi. Turn wifi off while charging. I used to charge 4 hours + on my S2. Reduced to 2 and some change when I turn off wifi.
Also, I struggle to make it through a working day with wifi on. Turn wifi off and I can do 4 days no problem.

I noticed my GN charges until 100% or "fully charged" (battery widget that spells it out). Shouldn't it be 97% or 98% max when charging to prevent damaging and preserve longevity of the battery? Or is this some new thing with 4.04 that it'll tell you 100% when it's really 97%? I do notice it drops down to 99% really quickly.
I'm stock on 4.04 and I'm using the provided USB cable and charger plug.
Thanks.
I take it you came from a Nexus S before? I was surprised too but I believe it cuts off the charging to prevent overdose of electricity. No worries on it mate.
It will charge to 100% of what ever value you set or as default comes.. Like you can see on the screenshot

Not everyone uses that.
The way the battery works is it charges to full, then takes itself off the charger until it goes down to say 95% and then at that point it goes back on the charger until it's at 100% again, so on and so forth.
Using custom ROM?
Maybe you need to calibrate the battery after you flash new ROM

Wiping batstats does nothing.
so basically it is safe to just leave it plugged in all the time then, the phone by default is DEFINITELY stopping charge at 100%, Correct?
because i know 2 facts about lithium batteries which i learnt today....never leave it permanently charging. and never let it drain fully all the time (the 40-80% charge rule).
im just worried that if i leave it plugged in it'll continue charging even when its at 100...
Do you know if - with that different kernel/ROM - whether you can set it so that you can leave it plugged in - and it won't charge past say....96%. And when it reaches that limit, it lets the battery drain back to say 40%. Before charging again - any software that will let you do this?

Is how phone even on the charger that long..? Something like over night won't kill your battery. The software is supposed to tell the battery when to take itself off of the charger and when to go back. You can use a kernel that will let your battery ONLY charge to a certain percentage.

You do know todays chargers have technology in them to prevent this right? They have for a while, overcharging is mostly a thing of the past, unless you buy cheap, flea market chargers.
in Recovery Mode there is an option called "battery ststus calibration" (something like this which I cant remember) . actually any percentage of battery use can be "calibrated" into 100%, the number is not important.
Okay, as long as charging up to 100% isn't damaging my batteries.
I did come from a Nexus S, and I always thought that when it stopped charging at 97% that was a good thing to prevent damage to the battery. So naturally, when I see it's going to 100% every night, I imagine it's damaging my battery.
Thanks all.

That's just because that's how the nexus s battery driver was written. The galaxy nexus driver isn't written with the 95% recharge limit. Its OK though there's no danger whatsoever leaving the phone charging overnight.

I've charged this phone almost every night since I got it (early June) and my battery is still doing outstanding. There are times when charging it over night the battery will set it self to draw battery so it can recharge and not cause harm I believe. There are many superstitious theories and others that "battery experts" say charging over night can be harmful. Overall I don't buy into too much. I always try to unplug as soon as it hits 100% though.

This use to be true on older phones. The galaxy S 3 and most new phones stop charging once they hit 100% it will only start charging again when it drops under 100.
And even before on older phones where it wasn't recommended I did it anyway. No harm done.

Overcharging protection, while present, can fail.
If you guys want to have a full charge in the morning, try an outlet timer - or put it in airplane mode overnight (I do that, battery is down only 1-3% after ~8 hours). You could also turn off data + wifi - so phone calls are still there if you are really worried about getting an emergency call in the middle of the night, the call function is still there, but apps aren't syncing and wasting battery and sleep time doing so.
I'm just not comfortable with the fire risk of leaving it in overnight. Sure, it probably won't fail - but if it does ? Why take that chance when there are other solutions ? I just charge it at my desk before going to bed, unplug it when it reports full charge.
It's the same kind of risk as putting a 100W bulb in a 60W socket - sure, you might be fine for a while, you might never have problems - but you might also start a fire when components fail under the stress.

Is there some sort of smart outlet that can stop charging when it reached 100%? I guess in a way the same as the outlets that has a master outlet and able to turn off the rest when the master outlet is off?

I usually let me charge overnight, it hasn't caused any problems for 6 months now.
It is true that your battery being at 100% charge (even if charging to the battery has stopped) is harder on your battery and overall capacity will lower at a faster rate than one stored at 60%. The thing is the difference is negligible over a year. It is technically best for your phone to be charged to 100% and then removed from charge so the battery can drain but we are talking about the difference of wether the half life of your battery is 3 or 4 years. overnight charging is not why your battery has failed.
