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.

98% here! Although I've gotten used to it now.

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.

Oh good to know this is intentional.
Dear all, somehow I am experiencing an odd behavior with the battery stats.
Once the battery stat reaches 1%, the phone still remains on for maybe another 15-20min of use until it goes off. Is there anything wrong with the battery, my settings or not proper calibration?

UPDATE:
Since my first post on 1% battery my note is still running. Playing music all time with switched off screen.....
Really strange behavior

Just a calibration issue I would think. Try resetting the battery data in recovery and also use Battery Monitor Widget to further calibrate it.

i was having similar problems with mine, i tried turning the phone off, removing the battery and then restarting the phone and charging to a full.....that somehow fixed the issue for me....and also as described above use a battery monitor widget for correct stats.
Did you discharge the battery fully first?
Sent from my GT-N7000 using Tapatalk 2
not fully, about 20% charge was left in it, but i guess it doesnt matter as long as you take the battery out and then recharge it back for a good 12 hours or so- supposidly longer charge cycles = more accurate stats.

I left my 8.4 charged with the wall charger over night, in the morning I found it's only 94% full, this happened multiple times, and I also tried another wall charger it still happened. The battery chart shows it stopped at 94% (some times 95%) and never went up. Does anybody has the same problem? Is there anything wrong with the battery? BTW, the battery life is not good for me, screen on for only 5-6 hrs on about 30% brightness.

stock rom, not rooted. I doubt it's caused by any app, if in that case the battery should still be fully charged then go down, but it's not what I saw.

Yes that's exactly the same as mine. I contacted Samsung support and they suggested to do a factory reset to see if it's a problem about software, otherwise I'll need to file a service request.
This happens all the time. If I reboot the tab will then show 100%.

Let it run down to 10% then recharge. do this a couple cycles. You could also try a battery calibration app that wipes the stats and starts fresh.
Solved my issue a while back.
A restart used to fix my issue but now the tab will say it's 100% charged and then at some point drop 10 or even 40% randomly.
Something is definitely wrong with the battery on this thing.
it's not the battery, but the reporting statistics used that is bugging out.

I found the problem has become worse and worse, sometimes it just stopped at 30~40%, then I said "f*** it", opened the back cover, pulled the battery out and put it back, reboot. Left it charged during the night. The next morning I found it charged to 100% !! Will post back if it really solved the issue after some more cycles.

I simply let the battery drain to around 20% and then charged it fully. Ever since (1.5 months ago), it has been reporting accurate battery %.

But the problem was the battery could not be charged to 100%, even if I left it charged over night, in the morning it showed 30%.
Mine works 100% perfect on ND3..
I have tried to make it do somthing weird..
I can't see anything in the ROM coding so far that would cause this..
So over a week later and my battery has been perfect.. Stock rooted nai....
4hrs 40 mins of screen on too..
Hi. I dont know if anyone is still on this post but i have this device and ive had this problem for the last year. It would get so bad with all the discharges that my battery died. I bought another battery and replaced it. I still got -300ma when connected to a 1A chaarger. So i replaced the flexi usb port membrane in hopes that would do it but i only got to 100mA. I bought a 2.4A charger and the tab doesnt even recognize the charger is in. Cant really turn it for service because I rooted it so my warranty is void. Any commentary and opinion would be greatly appreciated.:good:
I've noticed a trend of my battery dropping off like this. Granted I was playing games typically each time, but still strange to see such dramatic, steep drains, right?
I used to have this happen with my Tab Pro. This was one of the reasons that I got rid of it.
What I discovered though was that it was never fully charging to 100% so it would just suddenly lose like 20 or 30%. Next time charge up your Tab S and then reboot and make sure you are still at 100%. Not sure if it's the same issue. But it's worth a try.

Thanks. I just took it off the charger at 100%, rebooted and I came back up at 98%. I'll see how this charge performs.
I had an LG G Pad that did the same thing before returning. Would charge it to 100% let it go to sleep then all of a sudden it would be 92% upon waking up a few seconds later. Really really weird.
Same thing as before. I bought from Amazon. Time to start talking about a replacement? I bought this for longer plane trips and this isn't cutting it.
Have you tried Reset to Factory Default when battery is fully charged?

When this happens, plug it back into the charger whilst switched on until it reaches 100%, then see how it performs.

I have not yet reset it following a charge.
It's been on charge all evening now and just checked it at 100%. Following reboot it came up at 99% which is acceptable.
Doing a reset now and will report back. . Following this it's back to Amazon we go.

I feel mine has great battery life. I have mine overclocked and undervolted though. One charge has lasted me almost the whole road trip that I'm on from Kentucky to Florida. It's about 800 miles and 14 hours, not to mention I didn't even start the trip with a full battery.
Hi there,
I just got my phone and I thought the quick charging should charge my phone fron 0-80 in about 35 minutes...
I turned off the phone and from 0-35% took around 32 minutes which does not sound right...
Is it because the phone was turned off?
Or something needed to be set? Its the factory default charger.
Thanks in advance

Did you literally just get it and plug it in, or did you run it all the way down to 0% and then plug it in?

Well, the first thing you'll probably hear around here is never let it discharge all the way to 0% because it's bad for the battery. I'm guessing that, if you did let it go all the way to 0%, it might take a little bit to get going again, so the charging time would indeed be longer.

I am not sure why would it be bad for the battery?
Sent from my HTC 10 using XDA-Developers mobile app
If you Google something like, "lithium ion battery discharge 0%", you'll find all types of reasons why it's possibly harmful to your battery.
Nope.
Mine charges to about 40% in 30 Minutes. That's normal.

Don't worry about that 0% nonesense.
Smartphones are Idiotproof. You can't do anything wrong to damage them with normal usage.
Yes of course it's Bad for battery life (long term) if you drain it to 0% every day but until 4% is completely fine.
Why is it Bad to drain a battery to low? Take a look at the battery Voltage Graph in my Charging Chart. Charging is even more Voltage than discharging. If you use and App to check battery Voltage you will see about 3.7V at 4% and it Drops to 3.6.... 3.5..... 3.4V the closer it gets to 0%
Batteries don't like that.
Feels like my nexus 6 charger charges faster than stock HTC 10 charger
Don't just tell us about your feels.
Install the batteryLog app and let it run for a charge, then Export to file and show the csv here.

OK, quick look.
A Li_ion battery has a life cycles 400 - 500, that means battery can go from 100% to 0% normally 400 - 500 times, after that, battery will start to get problems, e g, you see it's 100% battery but in 30 minutes normal usage it goes to 0%.
If you charge the battery to 100%, then recharge it only if it gets down to 0% every single day, then after one year it's very likely you'll face the battery issues.
Yeah.... so if you recharge your phone not when it's at 0% but at 50% you will have around 800-1000 cycles...
AND you charge your phone about twice as much as the other guy who only charges at 0% so in the end you both end up with the same battery capacity after a year xD
P.S 400-500 life cycles means until the battery has 75% of its original capacity left, and not untill it's totally unuseable
