Hi all
This is my first thread - although I have been on xda many many years. I have searched the forums before posting this.
This morning whilst travelling to work by car I decided to recharge my Note (which was at 0% due to the previous day of use). I unplugged my Galaxy S2 and plugged the charger into the Note.
The Note would not take any charge from this USB car charger.
Now I know that the charger outputs 1000mA and that it was pumping 750mA into the S2 literally moments before.
I had started to think that the Note was bricked as the low battery and a yellow triangle were the only thing that the display would show, however, I could force the device to boot into Recovery mode (Redpill says the batt % in the corner - it stayed at 0%).
I tried a battery pull. I tried getting the device to reboot system from Recovery and I also tried wiping the battery stats.
The only fix I found was when I plugged it into a 1000mA AC charger.
Has anybody else had this problem? It could be quite an inconvenience if one were to run out of juice (ie 0%) whilst on the move, expecting to be able to charge from the car usb charger...
Moved To Q&A
Please post all questions in the Q&A section
Use Original charger and charge for 1 hour. do not try to turn it on. then try to turn ON.
if this doesn't work. try with different Note battery.
Hi. I got it to work eventually using an AC charger but my point was - has anybody else experienced this inability to recharge when at 0% and with only a USB charger or car charger available.
Samsungs recognise when they are plugged into AC Mains or USB don't they. Could there bee something in this that we may have to tweak, within a script during boot?

I hve this problem! Is it because I'm using non genuine chargers / cables?
I think it may be something to do with the juice it requires to get the initial kick from 0%... perhaps it will only take charge from AC in these .

I got this when i flowed all juice to 0%. I've used only genuine wall adapter / charger and got that triangle + ! too.. I just let it be that way and fired up Note few mins after that. Then it started to charge..

Yes, other users have faced this issue. It is not uncommon and has been in various posts over the last few months. As mentioned - use original charger and leave phone turned off for an hour or so - this will kick start it.
I had same problem with Blackberry bold - once below 5% would not charge unless I turned screen off and waited for at least 30 minutes.
I know this sounds all very well in hindsight, but I never let my phone drop below 20% - always charge it around that time. I still get around 2 days on average use but refuse to let it go any lower than that.
Would also recommend purchasing a second battery in case - with a separate charger.
Hope that helps - you are not alone
another one in the club......
i never let the battery go below 10%
below 10% my hands start shaking and my transpiration raise
at 5% i got defects to my view and i cant speack properly
below 5% my body becomes cold and covered by psoriasis.....

Within the last few days I've notice that my phone is charging at unbelievable slow rate via the wall charge that was supplied. I usually get a full charge in maybe 1-2 hr depending on what percentage the battery is at. Once it is fully charge it hold the charge, but when it drains then it would take like 6 hrs to do a full charge. I've tried to soft reset it to see if the percentage goes up, but it stay the same. I turn off the phone to let it charge, but it still charge at a slow rate. I'm wondering is it time to purchase a new battery.
What do you think? And is there any other test I can do?
The slow charge could be one of a few things... One could be the battery as you suspect (and probally most likely).. Also, are you chargign the phone in a diffrent place? If the battery gets too warm from lack of circulation, it will not charge (or just charge much mroe slowly).. It also could be that your USB port is starting to go... IF you have a stand alogn abattery charger available for it (like one on a docking station) try to charge it on there and see if it still charges as slowly.. Another though could be if you are charging it in your car while using GPS or Wifi.. IF those are left on, they suck down the battery a lot faster and thus it uses the electricity as fast as it can pull it in.. I woudl suggest powering the phone down while charging.. that could also help...
i always charge it in the same spot since i got the phone. i dont have a dock charger. its weird last night i was at 49 and i turn off the phone completely and plug it in. woke up today the orange light indicating that it was charging still was on. turn on the phone and it was at 55 percent. WTF!!!!!!!!!!
I guess that touch pro 2 better come out soon.

i have the same problem. Its either your USB port or the charger, so simply go buy a new charger and if it still does it the port is bad....if not, problem solved
or put it in your computer to charge, that avoids buying a new charger.
usb charging is always slower then wallplug charging as usb can only provide
5v * 0.5Amps == 2.5Watt
where
wall charger can provide as much watt
as the charger is made to
but of cause the pda will only draw as much
amps as it was made to support
Hello everybody,
I got my new HTC One just yesterday in the afternoon. I turned it on and battery level was 8%, so I proceeded to charge it while I was doing my initial customizations.
I took it out with me for the evening, when battery level was about 25%. Once I got home, I put it in charge (without switching it off) and went to bed.
This morning battery level was only 37%! Even leaving it in charge, it won't increase... So i went to recovery, did nothing, then did a hard reset and battery level became 63%!!
Now it is stuck at that, even leaving the USB cable for hours.
What can I do??
We need more info please
Are you charging via a mains socket or USB device, if its a USB devise then it may be that it is not supplying enough power
Use the charger and USB lead that came with the phone and power via the mains - its up to 4 hours
Remember it is best not to leave on charge overnight and try not to:
let it go flat
or
fully charge to 100%
I fully charge mine overnight and leave it on, let it die completely and so on. Never affected one phone I have ever owned, including the One.
Or, use the original charger as suggested for now. Let us know what happens when you use the equipment that came with the phone, plugged in to the wall outlet.

I wanted to quickly transfer something from my laptop to my new Droid Turbo, so I quickly grabbed a USB cable thinking it was my Droid Turbo's cable. I had accidentally grabbed my 2012 Asus Nexus 7 cable instead. I plugged it into a USB 3.0 port on my laptop and after transferring some things for two minutes I noticed my battery was at 100%. I thought this was strange as my battery had only a few minutes ago been 87%. That's when I realized I was using the Asus cable.
Should I be concerned? I usually almost religiously never mix chargers.
Edit: I have just discovered that the cable is damaged and partially pulling out from the USB end.. could this have anything to do with it?
I had the same issue, connected my phone to a USB 3.0 port to backup some date and was shocked at how fast it supposedly charged up to 100%. I used a 3 y/o cable from an old Galaxy S3.
USB 3.0 has nearly double the power output of USB 2.0. So that could have something to do with it. Using a different cable or slightly torn one won't make a difference. The battery percentages also aren't the most accurate all the time. Your battery should be fine.

A USB 3 cable going to a standard USB 2 micro port? No voltage difference.
---------- Post added at 11:07 PM ---------- Previous post was at 11:06 PM ----------
When using a standard USB cable the port does not matter.
I do think the calibration of the battery is off. I've had it go from 93 percent to fully charged on my qi charger just a minute ago, and yesterday twice, once on the turbo charger and an usb port on my laptop. I fully drained the battery the first day, Friday, and I think either it's still learning or the calibration is off. It seems to show it draining quickly the first sixty percent, then really slow down the last forty. Now I don't like letting the battery drain too low, decreases the battery life and capacity, hopefully it learns or next update clears this up.
This also happened to me on a usb3 port, but with the original cable. I jumped from 88% to 100% in about 5 seconds. This can't be right. Has to be a bug.
I don't think this is related to faulty chargers/cables. I had the same thing happen to me yesterday using my car charger for the first time (that I've used on 10+ other devices without issue) and the phone shot up to 100% in a few minutes. Ever since I used that charger all my other chargers that were previously working fine (turbo, qi, etc.), are charging the phone too quickly as well. I hope someone can figure out a fix for this, or an update comes out soon. I just wiped my device and set it up again, I'll report back if it's fixed.
I had this issue, I killed the battery thinking it would fix the issue when It charged, It did not. I factory reset and that also did not fix the problem. phone would show as 100% charged even when really only 3% charged. I ended up getting a replacement from VZW store.
Update - replacement phone from VZW is doing the same thing, only charger that I have used is a TYLT qi compliant wireless charger. (shows 100% for 6hrs)
Also are you guys on system version 21.21.12 or did you take the update?
Same issue here. Started today. Had since release. Exclusively use Tylt Vu charger. Have latest update. On Dalvik.

Mostly same here. Used the Tylt Vu exclusively, then used the Turbo charger once or twice. Phone was stuck at 100% for twelve hours yesterday, dropped to 93% after reboot. It appears confused as to what it should really be at. Seems that the Tylt Vu is the common thread here.
Fixed mine! after holding the power button for about 20 seconds the phone will shut off, I then charged the phone with the Turbo charger overnight which reclibrated the battery meter. This has not happened again since doing this.
Hope this helps!

This also solved the problem for me, thank you!! (I had also plugged into a usb3.0 port before this issue occured, hope they address this with a patch or some kind of fix).
I'm also having strange battery problems the past few days. The other day, randomly around 4pm I happened to notice my battery said 97%...just not possible since it had been off charger since 6am.. Yesterday, battery showed 35% and then died 2 mins later, powered off. Tried the power button for 20 and charged overnight, but on my qi charger I woke up to it only partially charged and not charging anymore. took off and put back on charging pad and it charged some more until morning. It seems the battery isn't calibrated and not showing the correct readings...anybody else? (oh, and it's a samsung charging pad)

unplug it from everything, hold power button till it shuts off, it will then show an accurate % reading. Plug into the turbo charger that came with it and walk away for an hour. Should re-calibrate and get you back to normal (assuming the issue you're having is the same as ours). this worked for me. good luck!

Sorry, needs to be plugged into turbo charger, I told you out of order, my bad.
plug into turbo charger, hold power till it cycles on it's own (you'll see the real %), leave plugged in and walk away for an hour.
Solved all of my problems, good luck!
(seems like this is caused by plugging into usb3.0 ports, and possibly some qi chargers. I use an lg qi charger overnight and have not had the issue. It happened to me when I plugged it into a usb3.0 port on a laptop).
great! this worked for me! thanks!
Well for me I've had this bug since day 1 and none of the fixes are permanent -- there's a bug in the software on Moto's side that needs to be dealt with. I posted a thread on Moto's support forum in hopes of raising the profile of this issue cause it's a showstopper for people like me who rely 100% on Qi.

Hi all,
I've had this same issue and I'm not sure when this happened, but I certainly noticed it immediately after using Qi charger for the first time.
Can we confirm if anyone on this thread had this issue by using a wired charging device, or whether this issue is synonymous with Qi charging?

it happened to me after being plugged into a usb 3.0 port, I use a qi charger (LG) every night without issue.
I've had my N6 for about two weeks now, and lately I've noticed it doesnt charge once I plug it in, I'll go to sleep and a few hours later its still at the same percentage, I check the battery stats page and it shows "Not Charging" I unplug it for a few seconds and the Charging icon sticks as like the phone thinks its still "charging". Another issue I've noticed just now today, it says itll take 4 hours to charge from 56%! Only way for me to fix these issues it is to restart the phone and itll work, mind you this issue only happens sometimes. Although I will say I plugged my LG G2 into the Turbo Charger, so IDK if that affects the charger in any way?
Does anyone else experience this? If this is something no one has I'm planning to swap the device out for another one.
Running SinLess ROM v1.0.3
what charger are you using for your n6? and where are you plugging into? wall or usb?

This may seem obvious but try a different cable. I had a cable that, when plugged in, my phone would say is charging but doesn't actually charge.
I've had my nexus 6 for a couple weeks now and the first time this happened I was using a wireless charge so I thought I didn't have it placed on the mat right. But it happened again last night whilst plugged into an AC charger. The AC charger is an LG charger from a previous Nexus. When I look at the battery graph it just flat lines for the whole time it was plugged in.

My turbo charger is doing the same thing the OP said. We have 2 6's and it also happened to my wife's the other day too. I thought it might have initially been a cable too so I changed that out and it happened to the second charging cable last night as well.
Just experienced this
I use the turbo charger also and just experienced this. I was at 25 % after playing injustice (which just murders this battery) and plugged in the USB and I looked back 5 minutes later at I was at 22 %. So I killed Injustice and waited about 5 minutes more and I was at 19%. I had to reboot to get charging and after 5 minutes of charging I was at 29% so it is weird stuff.
I've been noticing this as well, but my charger is an aftermarket charger by Tenergy (Amazon link), and I'm using an aftermarket cable. Missed my alarm this morning because the phone must have not actually been charging, even though the N6 always shows that it is charging. I haven't tested it thoroughly with the stock charger as I keep that next to my workstation, but it seems that others are having this issue even with the included charger. Frustrating, to say the least.
Same thing with my N6 on 5.1. I would say that 20% of the time i plug in it shows charging but doesn't charge, just maintains the battery at whatever percentage it was when i plugged it in.
I don't have to restart but rather just unplug and re plug in the charger, then monitor for a couple of minutes to make sure the battery is going up and if so it will charge normally.
I also have tried a few different chargers including the quick charger that came with the phone. same result.
the same. here
I have the same issue while charging n6 with Motorola terboxharger ... But it takes 3 h while charging with any other chargers .....any updates !!!

Wow, same here.... only just started to notice it. Using turbo charger as well...however upon using a normal charger, it seems to always charge. it it something with the turbo charger?
Yea it seems to be turbo charger problem , but how come I bought it just one month ago !!
I started noticing the same issue recently. I'd say it started after upgrading to 5.1. I'm using the stock turbo charger. I found a workaround that, so far, fixes it for me (3 nights in a row at least).
After plugging in the phone, I notice the battery icon shows it is charging. If I actually go into the battery settings though, it says it is NOT charging. If I unplug the charging cable and plug it back in while still in the battery settings page (you know, with the usage graph), then it starts charging just fine up until I get a full charge. As long as I do this each time, I seem to get a full charge. Annoying, yes. But not as annoying as waking up to à phone that never charged.
Sometimes it won't charge when it's not plugged in either
For my N6 to charge, I need to push the TC USB cable a little downwards for my phone to charge. Sometimes, it doesn't even charge at all. I'm considering to RMA this, if I can do it here in Norway.
my nexus 6 has different behaviours, if I charge it when it is turned on sometimes it stops the charging and I need to disconnect and reconnect the cable and charging starts again, so i need to be careful because i can't be sure that my phone will charge completely if i leave it alone. if I charge it when it is turned off sometimes it starts to restart continuously showing battery in the screen again and again, without charging. hopefully this happens sometimes, i dont really like this bug, i spent so much money for buying it and i dont want to control if my phone is charging or not when I plugged it, i just want to put in charging and coming bac when it is flly charged.
RMA it
I hope the first thing anybody does is check the charging port and make sure there's nothing in there. Take a strong, sharp toothpick and carefully dig anything out that shouldn't be there. Pocket fuzz etc...
I am having this same issue, my phone is brand new yesterday, running 5.0, I have these exact issues, seems to be only with the turbo charger because I use a slow charger for overnight next to my bed and the battery was full. But I can't seem to make the percentage actually go up with the turbo charger without restarting the phone first.
Any more info on this very annoying bug??
can't seem to figure it out
i have the same issue - my N6 is a couple of months old and it started on an overnight (not) charge. Now it's happening 1 in 2 charges so it's getting worse. I cleaned the connection, tried different cables, USB chargers and plugging into the laptop - no dice. It's going back to Google - annoying...
Hey guys,
I haven't used my Galaxy Tab S2 in a while now. When I plugged it in it was at 0%. I used "a" (possibly not original that came with box) OEM 2.0A Samsung Charger + Note 5/Samsung Official Cable to charge my tablet. It has only gone up by 5% in the past 30 minutes.
Also when it was at 0% it said it'd take 7hr 12min to fully charge.
Is this normal when the tablet has not been used in a long time, or am I possibly looking at a bad charger/cable as the charger and cable charge my Note 5 just fine at the normal (non-fast charge) speed where it charges my phone fully in just over 1hr 30 min.
If someone could help me out to resolve this I'd be grateful.
Thanks! :laugh:
Don't think the charger and cable are faulty as they work on your mobile. Generally whenever I charge my Samsung galaxy tab s2 using a different charger it shows a notification if the charger plugged in is slow. If it didn't show this I don't see why it would take so long other than the charger your using has a lower output causing it to take a lot longer than usual to charge.
Every android device I have will sometimes not charge fast enough - it doesn't matter what charger I'm using. If I catch that the charge is slow I just unplug it and replug it a it'll be normal again. I think the "smart charge" goes crazy sometimes.
I had the same problem on the tab s2 8''. It was because the motherboard broke. They fixed it under warranty.
When I had this problem I couldn't attach any external device (usb, playstation controller) through USB. Try if you can
I don't have the original charger anymore to compare on my 9.7. I use anker potable batteries to be free of wall sockets. It isn't 2.0. In battery monitor widget, really good app, shows charge anywhere from 1200-1600mA 20% per hour while in use during charging. 5 hours total. I think with screen off I get 30%. I get 10 hours of screen on time zero loss with it off over night. Using 5.1
It could be the motherboard. I know with laptops charging starts to mess up a few weeks before it no longer works at. The connection between the USB and board weakens over time/use.

Sounds normal. The big Lion batteries in these devices are just weird at time. Running one down to 0 is a good way to kill the battery permanently. Let it charge slowly and then keep it above 20-30% from now on. Should improve over time.
I think its a myth you shouldn't let the battery get low. As long as the battery itself says I'm at zero at the correct voltage then zero is perfectly fine. I'm not an expert here but at 5% battery I'm at 3.6v and will turn off in a few minutes after that. I think batteries are manufactured to safely go down to 3.2 before saying no more. Need to charge.
