Sometimes won't charge if plugged in - Nexus 6 Q&A, Help & Troubleshooting

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...

tilt totally dead, cannot recharge, cannot turn on, help.

hi, new member here.
bought my tilt on 10/4/07. has been flawless since that time.
used the nav quite a bit during a road trip, used a cig lighter usb charger.
got home and my battery was at roughly 40%.
put it on the charger at night went to sleep. in morning disconnected it at 8 am. shortly after i arrived at work i got the critical battery low chime. checked and it had like 7% battery life.
figured i didnt plug it in right, or it got knocked loose some how and didnt get charged.
put it in flight mode to minimize battery usage. left work at 2 30 pm (4% battery life) and put it on the car charger. got home and put it on the HTC supplied wall charger. light turned amber, so i assumed it was charging.
checked an hour later and turned phone on, it said 0%, and immediately died. left it on the charger for a few hours and the light was still amber, turned it back on and again 0% and phone immediately died and did a soft reset on its own. i turned the phone off and left it on the ac charger, took out the sim card and put it in an old blackberry to use while the battery was charging.
its been on the ac wall charger for the last several hours, i checked and the phone is totally dead, cannot turn it on, and the LED at the top is now RED.
what is the problem here? why wont this thing charge?
thanks in advance, i have alot of critical info on this device and any help would be greatly appreciated.
i cannot hard reset because i cannot turn the flippign thing on....
Does it charge when you connect it to your computer? If it does, then your charger is toast. If not, then it's probably the phone itself.
I'd try a different charger first. If that makes no difference then a different battery. If that still does not make any difference then time to exchange it.

connected to either the computer or the wall charger, the LED thats normally amber when charging, and green when charged, remains red.
I had something very similar happen to my wizard.
And as weird as it sounds, the only fix was to charge the battery in a friends wizard on his charger. I'd check the battery if possible.
Could be the battery. Know any place or anyone that will let you try a charged battery? If not, you might have to go in to an AT&T store.
i think i got it working. did some reading/browsing...
took a usb wire and cut the mini usb head off. dissected it and found the the red and black charging wires. took out the battery and held the leads to teh battery while the other end was plugged into a USB/AC adapter wall charger from a old blackberry. after manually charging the battery for several minutes, i put the battery back in the phone and the phone started up. now it seems to be charging off the wall charger and the led is now amber from red.
thanks for all your help/suggestions.
well it worked briefly. the amber light has gone back to red and it seems that the battery is not charging.
dont know what happened to my perfectly functioning phone.

Repeat this proceedure but this time do not turn the phone on, just plug it in to the wall charger once you have zapped the battery again.
Turning your phone on probably just caused the already recovering battery to die whiles it is trying to take on a charge.
It is mentioned quite a lot on the boards that Li-Ion Batteries do not like being over disscharged and there is usually a little protection circuit in the battery to provent complete disscharging although this circuit may be on board the phone. Completely disscharging a Li-Ion cell will kill it stone dead and it will need replacing.
When you took the battery out and so called jump started it with your flying leads, this possibly reset the little protection circuit in the battery so it can now take on a charge. I feel that once you turned on the phone, this was to much for the already depleted cell to take and possibly re-tripped its inbuilt circuit.
If you do manage to recover you cell, in future it is good practice not to let the battery go below about 25%. Li-ion cells are generally happy being top off regularly.
I hope this helps buddy
Do let us know!
Cheers

thanks, that was very helpful.
ive tried defibrillating this battery out of the dead several more times to no avail.
ill try it one more time when i get home from work, if its a no go i will go to teh att core store. the phone is 6 weeks old, dont know what they can do for me if the battery is toast...
That Sucks! I hope they'll give you a new battery.

I had exactly the same problem with my battery. It came on though after a day. Although the battery life after this happened went down to 10hrs max on standby. I sent the phone back and got a new one and now all is fine.
This is a problem that affects almost all makes of phone. There are three (main) causes of the problem:
1.
The battery charge drops too low to allow the charging circuit to recognise a battery is even in place (red no charge light stays lit)
possible solution:
http://forum.xda-developers.com/show...22&postcount=6
(in the end very similar in the end to the USB wire used in post above)
2.
A faulty battery (but if you can charge it using a cut usb cable or using a couple of AA batteries this may not be a faulty battery.
3.
A faulty charger OR a charger not delivering 5v at 1000mA as the OEM one does. Many chargers that are used for other phones or generic chargers only deliver 500mA. This is not enough when your battery drops very low. (these chargers are OK for occasional use but I do not advise using them regularly particularly if the no-charge syndrome has shown itself)
4.
A faulty USB connection on the phone. I have now seen a couple of reports where the fine wire connections in the phones USB port have become bent out of place.
Number 4 above is at least possible for the OP as it seems the battery will charge using a cut USB cable but not when either the PC USB cable or mains charger is connected. A USB port on the phone with a a bent internal contact would explain what's happening.
A previous poster was able with a needle or similar to bend the contact back into place.

i had the same problem with my phone.
put it in the charger overnight and woke up in the morning and couldnt turn on the phone with blinking red light. I don't know if my battery was over-drained though. I went to AT&T and was playing around with their charger and new battery and somehow the so-called dead battery started working again. They changed the SIM card on my phone there and then i haven't been able to use the phone since. I've changed the network to GSM instead of Auto setting under Phone Options which allows us to make calls; but now I can't connect to 3G network.
Charging thru mini usb
My phone started to exhibit similar problems...plugged in but no charging of the battery. I finally realized that my mini usb connection on the phone has been compromised (bent, distorted=not functioning properly) Now I have to prop the mini usb connection up at a slight angle to engage the charge. I think the plastic/metallic connector on the phone is somewhat fragile ...I had similar issues with my hermes.
called customer support.
they are sending me a new phone and battery.
how do i know its not a refurbished one? any clues?
before u send out your defect phone, have u check if your phone's mini-USB connector has bent or misaligned pins?
yeah all the connectors visually are fine.

[BUG] N4 charging stuck at 99% and other charging related issues

is it just my unit or anyone else have this issue? the battery indicator (lock screen and notification bar) shows 99% and just wont go up anymore.
UPDATE 2: Trick - when the phone stop at 99% while charging after a while, unplug the cable and immediately plug the cable back in. The battery indicator now should show "Charged".
UPDATE 1: Seem to be a safety mechanism to protect the battery from overcharged.
Also notice the following issues:
2) battery indicator may show as still charging when cable is already unplugged (only happened 2 times so far)
3) screen on by itself randomly while charging (not always but do happen some times)
4) battery discharging mechanism (to protect from over charge) may go haywire! It may go down from full/ 99% to 90% or less while still charging (may be related to (1) ).
Check your cable while charging. Also check to see if its charging as AC not USB. When it switches to USB, then screen will turn on.

Can't speak for the other 2 issues, but only charging to 99% isn't really a bug. This used to occur on the Galaxy Nexus. More reading here
Battery Charges Only to 99%
You can just ignore it, as it's apparently a way to safeguard the battery. Not sure the exact percentage point at which your battery stats reset, but it will have already occurred at 99%, for sure.

I was charging with AC, and I used a cable which is for charging only (can't transfer data). I tried it again today with the original cable from the Nexus 4 box, and have not noticed the screen turn on by itself again... Suppose it is the cable fault.
As for the stuck charging icon, it happened twice since I got the phone, but have not appeared again. Can't pinpoint the issue.

Ah... this is my first Nexus device. Surprised to find that it is actually a safeguard feature :silly: well as long as it is not faulty I guess I just have to get used to it. Thanks for sharing.
It has to be the dumb usb adaptor that comes with the phone. Mines charges perfectly fine to 100% using an LG AC wall charger I bought.. And even if I restart the phone it stays as charged at 100, USB would be at 99% when I rebooted..

yea my screen turns on randomly sometimes.
also, try this , when u plug in your charger to the wall but dont plug it into the phone , listen to it itll sound like its gonna explode.

[Q] Used wrong charger, battery jumped to 100%

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!

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?

[Q] Charging Query on Stock 5.0.1

I have noticed that when the N6 is on charge, once it reaches 100% and left on charger, the battery starts discharging approx 1% every hour.
I only noticed this when my alarm was going off and when looked at battery usage it was saying 94% but nothing using it - installed GSAM and noticed that once fully charged it starts discharging even while on charge. If I remove charger and re-insert it starts charging again as normal.
Has anyone else noticed this issue. I have contacted Motorola to see what they say, but they are none the wiser and just think it may be a feature of the device/charger but not sure and said to test with another charger.

Not sure, I don't use stock or the stock charger. I would have thought the stock charger trickle charged. I remember my HTC desire used to charge to 100%, discharge to 90 and then charge to 100% in a loop as it didn't trickle charge.
Make sure your using a cable that supports data as well. My stock 5.01 and stock charger/cable does trickle charge.
It's perfectly normal to see this in such devices, though if it were going any lower I'd investigate further.
Maintaining a constant flow to the battery would burn it out so the charge gets it to full and then cuts out, allowing a little discharging and cooling of the battery. Once it gets to certain point, it'll start to juice the battery again.
Sent from my Nexus 6
thanks for the replies - I've not seen it drop below 90%, but I know if remove the charger and plug back in, it will start charging as normal - another thing I have recently noticed is that when you do plug charger in, initially it switches between battery/charger a few times and then starts properly charging - I wonder if this is feature of the phone or lollipop causing this. - other than this phone seems to work fine and have had over 2 days on a full charge
Well got it to drop to 80% while plugged in and it didn't start charging again until pulled cable and put back in
what charger are you using? i leave my n6 on a charger for hours after it hits 100%, and it never ever drops. id even say that when it hits 100% it doesnt stop charging. it keeps charging, with a much less inflow of charge than normal, but its still charging. for about 30min before it stops charging. then it just stays at 100%. sometimes i have it plugged in for 8-10 hours after, never once did it go to 99%. this is while using stock, and custom roms.

The new gen chargers actually cut the power when the battery Actually hits 99% and show it as 100% and stop it charging. But when the 100% drop to 99% (which is not actually visible), it automatically starts charging. But discharging the battery more than 1% is not actually a Normal thing, I should say. I also do charge over-night, never evidenced such thing. I'll suggest you to try with different turbo charger if you have one.
I'm using the stock charger got with the phone. I did contact Motorola over this and they were useless. I know charger works as charges to 100%. But it then just stops.
I have performed a factory reset to see how it goes tonight.
If still no good will speak with CPW and see what they say as don't fancy having to send off based on some of the forum posts
I have no issues with my N4 which has been connected to a power source for days and still shows 100%
I have also noticed that on the N6 when powered off and charge it doesn't show that it is charging
taken it into CPW and they have sent it off for repair - been told 16 days - at least with apple it's near enough same day, shame can't do same with android phones
I had called Motorola uk support and was promised email confirmation of call and also call back this morning regarding the phone and have had neither
back to my Nexus 4 for time being, just hope my Nexus 6 don't come back with any scratches, etc
I use a Qi charger, and notice this exact thing. Charge until it claims to be full, then stop altogether. So I set it on the pad when I go to bed, and wake up to it not charging and being down to around 95%. I was thinking that it was a characteristic of Qi, but when we got another (identical) Qi pad for the wife's Hammerhead, it "appears" to remain in charging mode indefinitely. Our Qi pads have a blinking white light when they are "charging".
what happens if you just plug the charger directly to the phone so not using the wireless Qi charger, do you get the same fault

I use a Qi charger, and notice this exact thing. Charge until it claims to be full, then stop altogether. So I set it on the pad when I go to bed, and wake up to it not charging and being down to around 95%.

Hammerhead does act differently to the shamu. I have both and used them both on the same qi.
Hammerhead trickle charges. Charging icon remains until picked up off charger.
Shamu stops at 100%, charging icon disappears. However, when I remove my Shamu, its always 100% or 99%.. Its never lower.

Good question. But judging by the rest of this thread, I suspect that it will behave the same with a wire as with the Qi. I don't ever actually use the wire to charge, since the ballistic maxx case makes access to the USB plug inconvenient.

I wonder if that could be a coincidence....? I.e., either you aren't leaving it on long enough for the percent to drop lower than that, or leaving it on long enough that it initiates a top-up just before you disconnect it.
Ok, so looking at the DT for the device....
https://android.googlesource.com/ke...ot/dts/apq8084-shamu/apq8084-moto-common.dtsi
Look at lines ranging from 823 to 854 for the smb1357 block.
Note low-voltage-uv = 2750000, max-voltage-uv = 4350000
In mv, that would be 2750 and 4350 respectively. That makes for a range of 1600 mV.
The recharge-thresh-mv = 200
Assuming a *relatively* linear voltage/percentage curve, 200/1600 * 100 = 12.5%. It won't be quite that linear, but this is adequate to give a rough idea of the charge cycle breadth in percentage points.
recharge-thresh-mv accepts values of 50, 100, 200, or 300. The smaller the value is, the tighter the recharge threshold becomes. At 50, we would be looking at roughly 3%.
So my conclusion: working as intended.
There is another aspect that becomes involved when using Qi, which is the bq51021. This one has a parameter "resume-vbatt-mv" set to a value of 4270 mV. That is 80 mV below full, or roughly 5%. Judging by only the name of the parameter, it sounds like it sets a Qi charge cycle breadth of 5%, but I don't understand the relationship between the bq51021 and the smb1357. I suspect that the two have to agree for Qi charging to work.

I don't think so. I put it on the charger at pretty much the same time and take it off at pretty much the same time but starting from different % remaining every day... If it did drop to 90%, i would have caught it at least once by now.
update: whatever you do if you are uk customer and purchased via CPW do not take it back to them - i found out today that they are not accredited repairers and they should have advised me it needed to go to Motorola - now trying to find out what is happening with my phone and when to get it back
I'm still trying to understand how my Nexus 6 works with Qi charging, and the results are a bit inconsistent.
I'm using an LG WCD-100 stand and a BlackBerry Blade charger, both of which are reported to work well with the Nexus 6 (in portrait).
I've had my Nexus 6 on the dock on my desk in work this week, and have been keeping an eye on it. I have the screen on all the time (so I can keep an eye on incoming personal emails). Most of the time the N6 charges to 100%. It then stops charging until it get to about 98%, at which time it starts charging again. So far so good. HOWEVER, on a few occasions it did not start to recharge (even with the battery down to the 70's), and I had to remove it from the charger for a few moments and then put it back before it would start charging again.
I'll try again next week (I'm only desk-bound Tue/Wed/Thu) with a different Qi charger, just in case there's a problem with the one I'm using (though I doubt it).
In the meantime, has anybody seen similar behaviour - or is it time to talk to Motorola UK Support?
the charging issue with it not starting again is the same as what i'm having on wired connection - if you install something like gsam battery monitor you can see that it is discharging while actually charging
I also have the LG WCD-100 (from when I had the LG G3) but not actually using it as I think first time tried you have to get it in the correct area for it to charge
I had problems with my Nokia charger. Because this phone is big and the back of the Nokia was less than half way up the back of the phone, the weight of the too of the phone pushed the bottom of the phone away from the charger.. Imagine the phone as a see saw and the top of the back of the charger as the pivot point. Also the unflat back didn't help

Fast charging

Is there a set of rules that it follows before fast charging works? I'm not sure if it's that or my phone or charger is bad..
Seem like I can only get it working 30% of the time. I would have to unplug and plug in multiple times before the notification pops up saying fast charging.
I tried multi USB cables and pushed it all the way in the charger.
I haven't managed to look at kernel source yet (not yet released), but maybe charge type is not only dependant on charging source type, but current battery level. ie top off charging. Just guessing for the moment............
I have the same issue. The quick charging notification never pops up the first time. If I unplug the cable and plug it back in, then it's fine. I'm using the wall plug and cable provided by Samsung.

Don't know. I've only charged my phone 2x, but fast charging popped up both times.

I take it you got the sprint note 5? I just went and exchanged for a new one. Its giving me the same problem

Actually no, I bought the T-Mobile version. I doubt it matters but it's the 64gb model. It sucks that you exchanged yours and have the same issue.

I picked up the AT&T model yesterday. Plugged into my car charger, 2amp, works fine. Got home and plugged in before bed with samsung supplied charger, showed fast charging. Passed out and woke up to 40% battery this morning. Turns out it will connect fast charge (ONLY if i use the supplied brick AND cable), but cuts out after about 5 mins! If i use the 9v brick with a random cable, it will just say cable charging, but seems to be decently speedy and won't stop charging. Seeing how crawldit replaced his and has the same issue leads me to think Samsung really was hoping people would get the wireless pad. Hopefully its a minor software update/patch needed. Phone is a freakin winner on all other aspects. Battery life appears to be better than the note 4 even with a slightly lower mah.
Definitely a software issue IMHO, from the sound of it. Also, on my VZW 32gig I do not have this issue. Every time I plug it in (to the supplied charger) it fast-charged. Cant say if it gives the message every time though, but I know it fast-charges because its never on that charger more than 15-30 minutes and the charge jumps massively. But even on a normal charger it still charges fairly quickly.
Well... turns out my brick was bad, used the one from my Note 4 with the new note 5 cable and it works like a charm. I'd recommend checking out a new brick.
Glad you got it figured out. Mine works fine now as well. I don't know if everything was overly stiff from being brand new, but after a day or two the fast charge pops up the first time every time now.
