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.

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...

[Q] Battery or charger at fault?

I have a locked & unrooted WW TF700 & genuine dock on JB 4.2.1.
A week ago I started to notice an issue where the tab would constantly drain whilst it should have been asleep. Overnight it would loose ~30% instead of ~2%. I tried a few settings, but couldn't seem to solve it. I decided to do a factory reset because I haven't done one since I last upgraded to jelly bean. That appears to have cured that problem, but has created two more.
The first problem is that I can't seem to charge the tab over 81% when being charged directly. If I then plug it into a fully charged dock it will charge to 90% but no more, even with the charging cable in the dock.
The second problem is that the tab now decides to shut off at about 30% battery left. It won't shutdown as normal, just go blank and won't boot up again without being charged a little first. I have read threads about artificially overcharging the tab, but a symptom of that is the battery level will remain at 100% for hours before starting to drain normally. My tab won't charge to 100% and will start to drain immediately after removing the charging cable. Regardless I have tried to drain and recharge overnight with the tab both off and on but the tab won't charge past 76% overnight in either case. Restarting multiple times doesn't help at all.
For the first issue I started to suspect the charger may be at fault. This is because if I charge the tab directly, it will never get past 81%. However, if I then plug it into the freshly charged dock it will charge upto 90%. I understand that the dock will never charge the tab past 90%, unless it is plugged into the charger. Does it assume in my case that it isn't plugged in to a charger even when it is? I should mention I am using the original asus charger. Frustratingly I can't just use my phone charger to see if it solves the problem due to the 15v of the asus charger. I have noticed a slight hum/buzz coming from the charger but I can't be sure that it didn't do that before. I have had issues with the internal connections not be pushed together quite right before and getting no charge out of it, but 'clicking it together' a bit more firmly did the trick there.
Even with an overnight charge, plugged into the dock to get it to 90% I now get terrible battery life. Roughly 30mins per 10% juice. Previously I was getting around an hour per 10%.
Does anyone have an suggestions for me on how to eliminate the charger as a problem, or say doing another factory reset on a 'full charge'? The only other thing I can think of is to let it drain, give it enough charger to turn back on, then turn it off and leave it unplugged overnight (I saw it mentioned in another thread). I really appreciate any help you can give before I have to try the dreaded warranty route!

Try this with it undocked. Let the battery discharge to zero, and leave it 24 hours.
Then recharge it fully. This seems to cure the battery calibration memory issues.most us know how you get on.

Luckily I have located an Asus charger to borrow and hopefully find out if it is just my charger or not.
I also tried out CPU-Z and the battery is reporting as only having 7mV. I'm sure that can't be correct as my HOX+ is around 3500mV, and 7mV just couldn't power anything. I don't know if this is just CPU-Z issue with reporting correctly, or a clue that there is something not right with my battery? Has anyone else tried CPU-Z or know what the mV should be roughly, fully charged say?

Unfortunately a different charger didn't solve my issue :'(
I've posted a screenshot to show what is happening. I'll try draining the battery flat and leaving 24 hours to see what happens then. Luckily I still have two months left on warranty.
Pretty annoying because everything else the tablet does is fantastic. I replaced my laptop with it and use it daily for everything.

Unfortunately things have become worse. I tried using the tab until it died (at around 50% battery this time...) and left for 24 hours as suggested. Unfortunately now I can't get the tab to turn on or take a charge at all. I have tried holding power button down, with vol up/down, for over a minute etc. Tried the reset button all numerous times with no luck. All I get is the LED blink twice when pressing the power button and this only happens when the charger is connected, otherwise nothing.
I have the phone number for Asus support and will be giving them a call tomorrow. I'm so glad I never unlocked my device!

Leave it for 24 hours not on charge first then try again. We've seen this happen so many times - the fix is to let it discharge completely.

Thanks Sbdags, I appreciate your response. I've read numerous threads tonight with similar issues. I did try leaving the tab for 24 hours completely dead overnight last night. I'll try it again (I don't know if the battery is dead or not currently) but I'll leave it unplugged as there is nothing else for me to do with it anyway!

OK, I thought I would complete this thread.
After leaving my tablet for a few more days not on charge I could seem to get no life out of it whatsoever so went down the RMA route and the result of that is in the following thread;

The n8010 charging problem - My second Note 10.1 is about to be returned

I thought it might be worth writing a post about my second tablet's failure before returning it as I'm not sure whether to get it fixed/replaced or look for a refund. Maybe someone has some thoughts? After suffering the apparent failure of two Note 10.1's I'm getting worried that there is something fundamentally wrong with this tablet.
Now, I should say here that my tablet was bought refurbished. It shouldn't make a difference- I've bought plenty of refurbished tech before and I've never had problems like this but I thought it might be worth mentioning.
So, the first Note arrived faulty. It would not charge above 17%. The charge up to that point was faultless... It just wouldn't go higher than 17%. That made me think it was a software issue but nothing I could do would fix it. Back it went. It was swapped on the door so I know the second tablet was an entirely new tablet (with new charger).
The second Note I received has worked for just shy of 2 months before it too is having a lot of charging issues. It will only occasionally charge now- most of the time I can leave it for hours and it won't go up 1% but every so often it'll start charging again. The lead is fine but I can't check the charger as I don't have another to try out.
Due to my paranoia of charge failure I've monitored the second tablet with 'Battery Mix'. The graph created by the app shows a perfect flat line when the ac adaptor is plugged in. That in itself seems weird... If there was no charging occurring, wouldn't the battery lose charge rather than remain at a constant level?
The flatlining behaviour is what has me worried. Both the tablets had the same issue, the first just stuck at 17% whereas the second will stick at seemingly random levels. But the symptoms of the fault are similar.
Searching the internetz reveals similar cases as mine and, seeing as a refurb device only has a years warranty, I'm not feeling particularly confident in a third Note behaving itself over the long term.
Oh, and after all that whinging... I do actually love the Note 10.1 when it works. It's a really nice bit of kit which I am loathed to have to return.

I have had fits using the supplied stock charging cable. I bought an aftermarket cable & it charges perfectly. Unfortunately, I broke the cable two days ago & had to use the stock supplied cable. Charging is so slow it is ridiculous. I plugged it in yesterday morning at 7% & today, 20 hours later, it is only at 22%.
With the after market cable, it would charge to 100% from 3% in about 3-5 hours.

Just to follow up, I picked up a Samsung dock for the Tab 10.1 & used the charging cable from that to test it & my Note 10.1 started charging very quickly. It went from 21% to 56% in about 30 minutes.
I have no idea why the stock cable is so bad with charging, but it is definitely the culprit.
The Tab 10.1 dock is currently on clearance at my local Verizon store for $10. I am going to swing by later & grab the other one they had for a spare.

Cable is a noted problem in other Sammy forums on XDA .
jje

Thanks for the comments.
The tablet has now gone back for repair/replacement.... It's back to the old Hannspad for me until it returns. Oh joy.
I'm not sure the lead is the problem in my case although this is all just speculation on my part. I guess it makes sense in some ways- the charging became intermittent when plugged in which fits with the dodgy lead idea but when it played up it would just sit on whatever percentage it had been on when I plugged it in. Surely a bad lead would result in more uneven results rather than no change in charge (up or down) after hours of AC power?
I'm now kicking myself that I didn't save a screenshot of the behaviour as seen on the graph created by 'Battery Mix'. It was quite literally a straight horizontal line, no charge up and no discharge down. Most odd.
Fingers crossed the tablet will come back fixed. I have a fear it's going to behave itself as soon as it arrives to be tested but hey ho... We shall see. When it returns I'll definitely be investing in a third party lead.

With the original supplied charging cable plugged into the tablet, the device would drop in charge while in use. Meaning, it wasn't drawing enough/any power while in use. Also, it would sit at 22%. Never go any higher. I left it plugged in for 2 days & it never reached higher than 22%. This is on Jellybean. If I switched back to ICS, it would charge just fine.
I found several threads on the web stating exactly the same behavior.
I have since purchased 2 spare cables from Amazon, 2 Samsung branded travel chargers, & a Power+ travel charger, & ALL of them charge the tablet quickly & to 100%.
If I switch back to the supplied cable, it actually drops charge while in use.
I promise you, it is not the tablet.

[Bug] Charging phone while using results in shutdown with red led

Not sure if this is related to 4.4 or the nexus 5 specifically (pretty sure its the hardware). While using the phone during charging it doesn't charge fast enough to keep powered on. My wife was on facebook when hers went down, and I was playing knights of pen and paper when mine went down. The phone will eventually just power off and flash the red led 8 times. The only way to power it back on is to load the bootloader first (vol up + vol down + power) then press the power on start. I tested this on 2 black 32GB Nexus 5s with android 4.4.
This is really easy to test, next time your device is low keep using it after plugging it in. It will eventually just "go dark" and you'll be greeted by the flashing red led.
Here is a link to the google group product forum thread I created, please post feedback. This needs to get fixed, hopefully just an update can resolve it.

Yikes. This isn't good. The only time the phone may not be able to keep up with charge is when using GPS. If this is a widespread issue I'm sure it will be fixed. Unless you have a bad battery or charger! I will test..
Update:
Just played game Aurolux whilst charging for 10 minutes and phone gained 5%.
Sounds like you got two lemons

I tested it on both mine and my wifes phones, different chargers as well. Also the load on the devices was low, both were on wifi, she was using the facebook app, I was playing knights of pen and paper, both on auto brightness (in our living room, lights off). Same thing happened on both, screen just cuts out, red light starts flashing.
Hopefully it gets fixed, if more people will test it and post feedback here or at googles forum it would be great.

Same here. Zero issues playing games and phone charges.
Are you using a custom ROM or kernel? That could explain it. Otherwise you either have two did chargers, or 2 did batteries, or a combination of both.
Sorry.....

How low was the charge on the phone? Both of ours were under 10% when we plugged them in and kept on them. Both phones are completely stock.

28%
I guess I could try to charge when it's below 10%, but maybe easier is if you try charging whilst using your phone above say 20%. If you still have the issue then I think it's device related, if not report back.

I'm gonna give that a shot tomorrow. Its getting late and need to get up for work in a couple hours. Thanks for testing, makes me wonder though if it is my phones, or if its and issue with a low battery and charging/using.....maybe something related to the reason why you cant do an update until your battery is at 20% despite being connected to a charger.

you have faulty devices or chargers. my N5 charges super fast. over 1% per minute(until 80%) while it is on and being used
mine died this morning when i woke up. plugged it in and watched a few youtube videos while i woke up and let it charge

They seem to charge just fine when left alone. It just seems too coincidental that both phones would have the exact same power issue.

dont forget, the snapdragon has 'quick charge 2.0', you shouldn't be seeing that kind of charging issues. i mean, if it's something you're ok living with. but that sounds like a big indicator that the battery or charging module is faulty/will go bad soon

No I'm already getting mine replaced for dead pixels but to have 2 phones experience the same issue like this is weird. Need more people to test the phones under 10%, I know they charge fast but there could be a reason why behind this like I listed above.

The only thing I notice is the charger does get quite warm when charging, but it's very fast.
It does sound too coincidental, but not impossible.
I hope it works out for you.

could it possibly be the cable, or the charger unit, or even the wall socket? these are all things that should be tested

I just wanted to say that I had the same issue as you and the problem so far seems to happen when you let the battery get pretty low before plugging it in.
The battery was down to about 8% when I plugged the phone in last night (to the lg charger). I actually left mine alone for about 30 minutes and when I came back, it was at 6%. I did verify that the display said "Charging" when the cable was plugged in. I unplugged the phone, and plugged it back in and started browsing the web on wifi and within another 15 minutes the battery had gone down to 2%. I turned off the screen and left it alone and when I checked it again, it was at 1%. At that point, I was worried about the phone, so I urned off the phone completely. When I turned it back on, it did look like it was charging again, but very slowly. At this point, I tried plugging it into another charger that I had, and it charged up fairly quickly.
Definitely pretty frustrating as I've never had something like this happen unless you have the usb cable plugged into a computer.

Last night I went to plug my phone into the lg charger...I could hear the charger buzzing slightly....I plugged in the phone and thought nothing of it really... Looked at my phone on the way to work and it wasn't charged past 28%.... plugged it into another charger at my desk and its at 47% in a matter of minutes...
I know op said he tried different chargers, but just tossing in my lousy 2c

The only chargers I tried were the ones that came with the phones. I got a bunch of others so Im going to give them a shot as well and see how this fairs.

Ok so Im sitting here trying to recreate the issue and it is different. I brought the battery down to 4% plugged it in and kept playing kop&p and the battery hasnt gone down, it actually went up to 7% but its holding there. I am letting it get to 10% now before I pick it up and try again. I swapped out between the n5 charger and my n4 charger both held it at 7% while playing.
Maybe this just has to do with battery conditioning, or maybe the snapdragon quickcharge ic.
Just checked the phone, from the time I started writing this till now (maybe 2 minutes) its up to 10% so back at it I go.

The charger that comes with the phone is horrible. Its the same type as the n4 which dies after 2 months. Don't use it, just use another one and you'll be just fine.

[Q] Battery problems

I hope I am in the right forum for this...
Lately my two year old tf700t won't stay on for more than 10 mins at a time. I have the dock and both parts say more than 100% charged.
Due to my device being out of warranty and thinking something was wrong with my stock asus rom. I downgraded the rom, rooted it, unlocked and tried several different roms.
My tablet is still turning off even though it says it is 100% charged.
Is my problem a bad battery? I think it has discharged "fully" (to where it warns me) maybe 10 times in the two years i've had it in the dock. It has almost always been plugged in or lightly used around the house. It has never been drained and recharged repeatedly to the point that I would have thought it to be worn out by now.
When I've had batteries go previously, they just drain fast from 100% to 0%. Both batteries are at 100% and it won't stay on but maybe 10 minutes unplugged. When I plug it in, it takes about 5-10 mins before it turns back on again. Meanwhile, the led by the power button blinks orange like the battery is dead. When it turns back on, it tells me I'm fully charged. grr
Does anyone know what is going on? Is there a way to test the battery or is there some chip inside the thing that needs to be reset or something.

It sounds like that you have a calibrations issue with your device. When your device is shut off by itself, you should leave it unplug about a day. Then recharge your device after a day of depletion and hope that it will solve your problem, good luck...:fingers-crossed:

Mhhhh - "almost always plugged in"?
Not the best use for these batteries. 2 years of that could have killed it.... And then - may not have anything to do with it if the battery went bad. 2 years is not an unreasonable life expectancy for a battery for a portable device.
In addition to LMK's suggestion, you could try this:
Let it die and then sit for a day unplugged.
Connect it via USB to your PC and let it trickle charge for 8+ hours (charging indicator will not even come on). Make sure your PC doesn't shut down or go into sleep mode during that time.
It should be charged enough to boot it. Check if it made a difference.
