Overcharging the battery?

Is it possible to overcharge the battery? I ask because when I first got the phone and fully charged it, it would stay on 100% for at least a couple hours (using circle battery widget which reads in increments of 1%) but one night I fell asleep with it plugged into the charger and when I got up it still read 100% but as soon as I unplugged it it went immediately to 99%. I have not yet been able to get it to read 100% unless its connected to the charger. Think I could get the batt replaced under warranty since its only 2-3 weeks old?

Your battery is fine, it is set up so that it will not overcharge. I tried searching for an article that explained how the system is set up but couldnt find it.

I'll look in to that. But what about the battery immediately dropping to 99% when I take it off the charger?

Every android phone I've had has dropped like that as soon as I've taken it off charge, nothing to really worry about.

They do a think called power cycling. It will charge it to 100% then shut off then once it goes back down it will charge it to 100% again. Ill try to find the article. Your battery is fine.

Weird. My SE Xperia X10 didn't do that, it would stay at 100% for at least an hour. I recalibrated my battery a couple days ago, thinking it would remedy this "problem" and after it died on me I charged it back to 100% and took it off the charger at 10pm, set my alarm on it and let it sit overnight. After pressing snooze on my phone 3 times and finally getting up at 630am it still was at 100%! So it's strange to me that this drops to 99% immediately but if it's happening to everyone else I won't worry too much.

Well if I were to judge off that, mine stays at 100% for hours......im going on 7hrs right now. But I use battery circle widget which reads in 1% increments......as soon as my phone comes off the charger it goes straight to 99%......it didnt do that before.

Battery Charging & calibration query
What difference does it make if you charge from empty to 100% in switched off stage and the same in on state? Which is better? How should we calibrate the battery and how often using which app for unrooted MB865 Asia retail? Also if phone dies (switches off) constantly due to insufficient charge does it harm the battery in terms of cells getting destroyed gradually & finally does switching off or switching on the phone while charging have any effect issue on phone or the battery?? Thanks in advance for inputs for all queries.

[Q] Charging Paused can't do anything

Hey guys...yes this is my first post. I've been searching for about 12 hours and reached my wit's end so I ask for your help
I've got an S2 Skyrocket running unrooted 4.0.4. It's run fine for almost a month with no problem other than terrible battery life.
Starting yesterday, with 2 different batteries and 3 different chargers, i get an error telling me "Charging paused. Battery temperature too hot". Its not even warm and it will not charge. Now both of my batteries are dead and I cant get the device to even go into download mode or anything.
I had a 100% charge on the phone yesterday and turned it off. When i turned it back on (or tried to) it was totally dead.
i'm on the verge of smashing this thing into the ground. Please help!

Charge the battery on external. Then Odin stock

Thank you so much for the quick reply. Almost rhetorically I'm assuming there's no way to externally charge the battery without an external charger. Correct?

right

I used to get it all the time. Just ignore it.

I would ignore it, except that my phone doesn't charge. And it pops up every 60 seconds or so if I click ok and try to get out of it.

**Update - I've borrowed a battery from a friend with a Nexus. Device powers up, was able to revert back to stock 2.3.5 but still same issue with all 3 batteries and different chargers...Charging paused due to battery being to hot or too cold. Trading in for a new Skyrocket at ATT service center tonight under warranty....

[Q] Roms and battery life - Unable to start phone

Hi,
I have recently tried out a few ROMs with my Nexus S to try to get better battery life. I tried CodeName Android and then figured I would try Slim ICS afterwards. I completely wiped everything and installed Slim ICS.
I have observed the following:
- Battery was ~40% when I installed Slim ICS
- I used it until the battery depleted
- Plugged phone into the wall charger
- Started the phone shortly afterwards (~25 minutes) and it says battery is 100% and then the phone randomly shut off
- Phone has been plugged into the wall charger and when I try to start it now sometimes it boots completely and then shuts off. Other times it just shuts off before it finishes booting up. The few times it does fully boot up, it says the battery is 100%
I've read through many postings about calibration but at this point I am not even able to fully turn on the phone even when its plugged into the wall.
Is this expected or is something else going on? I've never seen anything like this when I had the stock ICS. Why would erroneously report 100% but then not even let me fully turn on the phone? Thanks!

Maybe a bad battery?

Battery is fine. I ended up letting it charge a few hours and it now fully boots up and battery is almost fully charged now.
Whats strange is at times, when the battery was close to empty, when turned off and plugged into the wall, it showed the battery as being completely charged so I don't think it was charging. I had never observed this behavior with the stock ICS.

same problem
Even I have faced the same problem whenever I reboot keeping my pfone charging,
This is very normal,
just let the battery drain completely and next time charge it till 100% it will work perfectly,
It happens with me whenever I install new rom.
basically the battery indicator shows incorrect status also battery will drain very quickly later but once you finish installation just let your phone charge for 3 hours . Problem will get solved

Thanks. So it sounds like its more of a generic issue with ROMS in general as I never observed this before putting on a custom ROM.

charging issues jelly bean

well is it only me having charging issues with jelly bean? a quick search in google proved that a lot of people with other phones when they updated to jelly bean have charging issues (very slow charging, even on power u cant work tablet even in power save mode it stills droping!
anyway couldnt find anything here fore note 10.1! so what about you guys?? i had to go back to ics cause of that

with or without JB you will have the charging issue its not an issue but because of the huge battery note has

ofc its a rom issue as when i go back to ics the charging its ok! in jelly bean its very slow! i mean i put on charge all night and only about 20% charged! its not hardware problem, but jb issue. i just dont see anyone else here with note 10.1 complaining about this.

Don't have that problem, Only goit 3hours sleep last night and plugged in note before going to bed. Fully charged from 46% in 3 hours.... You might have a problem with your charger/cable/charging port....
If you have an S2,S3 or Note 2, or an old Gtab, the charger works for your note so you can check where the problem is....

Only charging issue I have is when I use different charger other than the original one then its slow..if I use the original one its fast

The OEM charger supplies 2 Amp hours of current to the battery. If the battery takes any more than 3.5 hours to charge the 7Ahr battery then there is something wrong with the tab or the charger.
Sent from my DROID BIONIC using Tapatalk 2

Note takes around 5 hours to do a recharge, but if you have extention USB cable of a after market USB connector for longer length it will increase the charging time

Max charging time for me with OEM is about 3.5 hours with power saving mode on and screen off, or around 2.5-3 with the tablet OFF. Thats with a 6-9% battery remaining. Anything much more means something is eating your battery in the background while you are charging.. make sure you use OEM charger.

my charger was slow charging right from the box. They gave me a new one the next day and everything is fine now.

Thats odd. I never had any charging problems when i upgraded to jellybean. Have you compared your unit with someone who also has a note 10.1?

I picked mine up on Thursday and charged it to 100% with the supplied charger and cable, installed the 4.1 system update and used it throughout the following day watching video and general playing. I had it plugged in whilst I was using it and noticed it discharging, odd I thought as it should at least have maintained its charge but after my battery level dropped to 19% on that evening I turned it off completely and left it overnight, this morning it had only charged a further 20%. It has to be a firmware issue as its the only thing thats changed since I first charged it fully without any issues (first charge on 4.0 took approx 3 hours from unboxing).

I also have the same problem. Any solution to this?

I also want a solution to this.
I'm at wits end and feel like smashing this thing.

Power off completely while charging it will go faster.

No. Its still doesn't charge faster. Same result.
Its going back to Samsung today.

That sounds screwy... I have mine on all the time, plug into the wall and about 3 - 5 hours later its fully charged...
Might be the wall charger is the problem, Samsung may have a batch of faulty chargers....

Doubt its the charger. Because its now 100% full but still says charging, not charged like on 4.0.4.
Even my battery stats don't reset anymore.

In my opinion something happened in this OTA. Been viewing many 10.1 forums for a while now and never read anything about charging issues. Since the update, its an issue unless all of us just happened to either have faulty chargers at the same time or we all downloaded the same app at the same time which is the source of the issue. Im gonna say its not neither of those because what did happen, is we all downloaded an OTA at the same time and have since had this issue.
One thing I have noticed that works a little better for me is to do a reboot right before I throw it o the charger. I dont unlock it or anything, just keep it on the charger.
Im thinking of rooting over the weekend and trying a few different ROMs to see what happens.

Just a thought, but lots of people are complaining about this and lots of people are not experiencing a slow charge.
The update has been rolled out in many countries now - so what country are you all in and what sort of mains power do you have? Maybe it's something related to that

Shouldn't matter as the charger is the one in charge of voltage to the Note.
You can use a charger from America in Australia, UK or Europe (with an adaptor of course) and it should charge your note the same everywhere.
I have tested this by using a stepdown transformer to charge my note at 110 volts as well as the normal 240volts we use here in Australia. No difference.
I have an overseas model Note and need an adaptor to connect to the Oz mains. I also have another note bought here in Australia and it works fine using either Australian or overseas charger too at either 110V or 240V...

note 10.1charging extremely slow

My note 10.1 is with something rom jb4.1.1
Fewdays ago, I found that my note 10.1 charging speed becomes extremely slow. For example, I wentbed with 50% left , and after 7 hours of sleeping, after I woke up, it was only 88%
This never happens in the past, and only start in this few days
Any help?

Try a different mains wall socket. This has worked for me in the past.

Try the usb connections are firmly connected
Also like a member suggested try a different power source and a non upa source is preffered
Check if you have not left any application or game running in the background

All of a sudden my note has become extremely slow to charge.
Tablet was off whilst charging and only managed 8% an hour. After 6 hours charging it was at 50%
What happened?

Do you have a big red x over the battery icon?
Sent from my GT-N8010 using xda app-developers app

I have a feeling that the power saving mode on slows the charge down. That's the only setting I had changed recently.
Ill test tonight.

Charged overnight and battery charged less then 50%. Ive had it had on charger for hour and a half and has charged 7%. I think it was the update. Many problems for me since update, but this is the biggest one.

I had the same issue for a bit. Someone said to try disconnecting and reconnecting the usb from the power block about 4 or 5 time relatively quickly and that fixed it for them... tried it and have not had an issue since even when connected to an extension. But also make sure its firmly in.
Oh.. and do this with the note plugged into the mini end of course

I have to say that I have been very happy with the crazyondigital wall charger that was bundled with my case. I used the OEM charger for the initial charge but began using the crazyondigital charger because it's more convenient due to the fact that it's longer. It also seems to charge more qiuckly. Perhaps slow charging with the OEM charger has something to do with the USB wall wart wiring design.

I seem to have the same type of problem I had mine on charge for 2 days now I done nothing different in the way I normaly charge, I tried both having ny note off over nite and with it on both with no luck, both time my note not fully charged.
This started on Friday gone,
If this dont charge soo. I will try factory reset since thats the other option bar getting a new charger

You sould try to use the device till it dies then try to charge it again see what happens, maybe wipe battery stats if you have cwm. Also try to get one of those battery stat monitoring apps and see if its registering proper voltage and heath

Had the same problem yesterday. my note went out of energy and shut down. So, after a while I connected it with the cable to charge. And what happened? After a hole night I got only 50% -.- I was like wtf?? then I tried the galaxy s3 charger and there was a red cross on the battery icon. Then I tried the note charger, again nothing, and like the other poster said, after a few times in and out it worked again.

another one here with slow charging, this is a big problem, its so slow it means it drains when you are using the tablet when its plugged in, you should be able to use it and charge at the same time. I could understand if it didnt charge much when I was using it but to not charge at all is a real fail.
Has anyone logged this issue to samsung?

Nothing has solved this problem for me.
Taking 8 hours to charge 79% is just beyond comprehension. Can't use it plugged in as it drains anyway. I want a update asap or I'm ditching this tab.
I don't know what caused this, it was fine a few weeks after the update and suddenly crippled.

So it's not the update then? If it was fine for a few weeks and then suddenly crippled JB is not the problem.
More likely an Application is NOT properly compliant with JB and is draining battery or hogging

Nothing shows up as running and hogging the battery. It doesn't drain fast once charged. It just charges slow.

Indeed, it charges so slow it drops when you are using it plugged in, if anyone has registered their tab properly with samsung perhaps they could log a fault, I havent had chance to do this yet.
Also, has anyone tried switching back to stock to see if it resolves it?
