I was under the impression the charging capabilities of this phone were insane? My note 4 is charging very slow even with the phone off. Ive toggled the Fast Charge on and off (battery page in settings) and regardless of what i chose its very slow. I think my Note 3 charged faster than this. Is something wrong with my charger or my phone? Should i echange it for another?
Exchange it. With the included charger mine charges in about an hour.

The way fast charge works is with wall adapter and cable that came with phone and screen off. Another way is phone off. Takes a bit over an hour when phone dead
NOTE 4
Looks like I'll exhange it then, cause with the phone off, it took about an hour to go from 25% to 38%. Its strange cause my note 3 was usable while using GPS, and phone connected to car charger, not even a 2.1amp one and it would charge quickly. Note 4, actually went from 38% to 52% in about 3 and a half hours the same way
Mine is the opposite, charges fast and and drains fast. When I unplug it will go from 100% to 95% in 5 minutes with no use and screen off. I tried several battery app with no success to fix the problem.

Fast charge will only work screen off. If u using GPS then phone is awake and u get slow charge
Also make sure fast charge is clicked on.
NOTE 4
Did you take off the plastic stickers from the charger? Mine started fast charging after I did that. I think it was covering part of the connection somewhere.
I hope u connected to ac and not USB check battery in settings make sure it says charging ad and not charging usb
Yes mine says it is charging via AC. I havent removed the plastic from the charger, ill try it. The weird part is, last night i had 5 percent battery. At around 2:30 i turned off the phone and connected to the charger. I wake up around 9:30, a whole 7 hours later, and the phone only charged up to 89%. It takes 7 hours to not even charge full percent? Is that normal? Granted, if i turned off the phone or even had it on, my Note 3 charged within 2 hours or less even from dead. So i should just exhange the phone right?

Bad phone
NOTE 4
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 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

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
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.
So I recently picked up a T813 to replaced my Nexus 7 (2013), I've had a few weeks now, and as with all my devices I slow charge it. This tablet generally took ~30 hours or so to charge at 0.35-0.45 amps, but I didn't think anything of it. This week I went on a trip and plugged it into a charger that can output anywhere from 0.8 to 1.8 amps depending on the port you are using (all the current ratings I'm listing are what I've measured, not what the devices are rated). My tablet said "Charging" at first, but then once it hit 75% all it would say is "Charging Slowly" no matter what. Now that's all it will say. Sometimes after a restart it will say "Charging" briefly, but then it goes back to "Charging slowly". The charger I was trying to use was an Anker product, so not a complete "no-name" charger.
I did some more checking and it appears my tablet has an upper charge limit of 1.5 amps using even the factory charger which is rated 2.0 amps. That same factory charger plugged into my Nexus 5X outputs 1.88 amps. Anything less than 1.5 amps, my tablet behaves as the rest of the devices. If I plug the tablet into a power source that current is limited to 0.5 amp, using the same cable, using an Honor 5X, and the Tab S2, both draw the ~0.5 amp.
Now the "Charging" and "Charging Slowly" messages were on Lineage, however since I have returned home, I and done all the subsequent testing, I have used Odin to return completely back to the factory Samsung software. Right now I have some videos playing to run the battery down, and am planning to trying to charge the battery all the way up using the factory charger to see how long it takes. If it also takes 30 hours, I'm going to assume it has to be a hardware problem?
Anyone else have any ideas?
My T813 arrived with Nougat on it. The only Odin firmware I could find that would successfully flash was a Marshmallow so I let videos play overnight (which did actually play overnight surprisingly!) to fully drain the battery. This morning I started charging the battery with the OEM charger, and from fully dead to 100% it took roughly 4.5 hours. So I would say this is normal from what I've read. I would say this rules out any hardware issue.
My next test will be to find a flashable Nougat OEM image as it doesn't want to update itself. Then see how it performs then. I'm starting to wonder if Samsung changed something in the firmware to make it charge slower on purpose just to prevent any "Note" like issues from happening? Finally then I'll have to also go back to Lineage, as I don't plan on using it at all with the stock software, as it's quite unbearable. There's a reason I only buy devices that Lineage is available for.
So after updating to Nougat, and letting it update, then fully draining the battery again, which again took overnight, it seems to charge even faster. This time from 0-100% taking just under 4 hours using the OEM charger, at roughly 3 hours 45 minutes.
I'll put Lineage back on it tonight, however this definitely calms my concern that I had a hardware issue. It's definitely fine. I'll see what kind of charge time I get with Lineage.
It charges with ~1600mah
I've had slow charging issue twice. I sent it in the first time and Samsung sent me a slow charger (not fast charger) to use. Worked fine for about 10 months. Once I update to Nougat, my charging became slow again.
Seems like many people have slow charging issues with this tablet. I have the Verizon tab s2 9.7

Yeah this is what I've noticed. This seems to be about the upper boundary. Despite being shipped with a 2 amp charger. I did reinstall Linage, and it charges fine with the OEM charger, so it's not a bug on their end, or a hardware problem for me. With LOS and the OEM charge it's still ~4 hours to charge with is what I would expect roughly based on my other tests, even though LOS still reports charging slowly.
I think my problem early with the 30+ hours of charge time was related to the hub I was charging with. I have been having issues where I would wake up and my phone wouldn't be charged at all. Most nights it would though, so I figured my cable was starting to go bad. Swapped the cable and same issue. Measured the current on the ports, and it was far below what it should be on a USB port, the charge ports were getting 0.18-0.2 amps, the regular ports were 0.2-0.3 amps (not sure why the regular ports were getting more). Then I noticed the power adapter was not plugged in all the way into the wall. After plugging it in all the way the current on those ports returned to normal. This honestly doesn't make any sense to me, so it maybe time to replace that hub. Either way, I know the problem is not the tablet, which calms my fears about it, since it was the new piece of hardware.
