Ok, so I have my Nexus 5 for about 8 months, but the charger that came with it doesn't work properly anymore.
Just after I got it, and few months later, the charger worked pretty well, and I also have a small amp meter that is connected into charger's usb port to measure Volts, amps and mAh, and when new, it pushed about 1.7 amps of current (it is rated to 1.8), and charged the phone in about hour and a half from 5% to 100%. Right now, the charger gives only 0.4-0.5 ams of current and charging time varies from 3 to 3.5 hours!
Has anyone experienced this problem?
Is an LG G2 (2.2amp) or G3 charger safe to use, as I tried G2 before and it charged the battery in less than an hour, without heating the device.
Also, I frequently leave my charger plugged in wall socket all day long, and it's plugged in without using more than it is plugged out (just when carrying it somewhere). Maybe that's why it degraded over time...

Hi guys, just realised my Nexus S takes pretty long to charge up.
Hoping for more users to come in and share ur charging time and also to check ur charger whether it's rated at 0.7mA for output?

How long is "pretty long"? Mine takes around 3 or 3 n a half hours usually.
But when I used my iPod's wall charger it was comparatively faster. iPod's is 1mA.
my wall charger is 5v/0.7a, takes around 3-4 hours for a full charge, but i leave it to charge overnight ready for the morning so not 100% sure
after charged to 94-95%, stay with display on and will charged to 99-100%

Define the "pretty long" term.
All Nexus S's come with the 0.7A wall charger. So the math is the following:
1500mAh / 700mA =~ 2h - DC current
1500mAh / 500mA = 3h - USB plug
So it should take aprox. 2 hours for a full charge with the wall charger, 3 hours with USB connection. That's theoretically speaking.

at least 4 hours on the wall socket.
Mine takes around 4 hours too. My Captivate runs circles around my Nexus S while charging. But the battery on the Nexus tends to last longer running the same programs. Both have 1500mAh.. Weird.

About four hours from 1% to full via wall socket. Give or take a little.
I use Battery Monitor Widget to track what is going on during charging. To avoid blowing up the battery, the charging circuit pulses the battery with current and a different profile appears to be used on USB as opposed to AC. I tried a heavy duty USB wall brick and it made no difference (1000ma/H) - the GNS still reports on USB charge so the AC wall charger has a wiring difference to USB. Some say the data lines are shorted on the AC charger telling the GNS that it is plugged directly and flagging the higher charging profile.
Basically the AC circuit takes about 3 - 3.5 hours and the USB circuit can take 4 - 5 hours. USB plugs are limited to 500 mA (or USB 1.0 used to be so I am concluding that USB 2 is the same). Anyone know different ?
The 97% charge limit seems to be the circuit limiting overcharge of the battery and if when fully charged you disconnect the charger and immediately reconnect you can squeeze an extra 2 - 3 % in to the battery. Mine reports 99 or 100 after such a cycle.
To make sure your GNS battery circuit is fully calibrated run the fone completey FLAT once in a while (50 charge cycles). This makes sure it knows what is flat and what is full. Before I did that it could take 4 - 5 hours or more to charge. After flat cycling, it is quicker. Use Battery Refresh Beta (maybe full version now) from the Market to flatten the beast........
All this assumes the stock 1500 mA battery pack. Anything else (1400 cheapies labelled 1600 or a fat 3200) will be different.
This is in stark contract to my XOOM which doesn't pulse at all but simply wacks 1500 mA in to the battery until it is full. Maybe heat disappation is not such an issue on the XOOM. I can't imagine the battery techology is much different but I don't know for sure.

Hey all,
how much time it takes you to full charge it?
my battery was ~10% 7 hours ago, i went to sleep, and now its still charging ~95%
im using htc charger, and its connected to wall, and its just taking him to long.
tnx
not sure ...my charger seems to work fine..few hours but on usb need soooo loonnnggggggggg...i know its faster on charger but on usb is just too much..
My significant other has the same problem with her Sony ericsson charger (she has an X10 Arc), my charger on the other hand works perfectly.
If you have the possibility of trying another charger, you can find out where the fault is...

My battery was charged from 23% to 100% in 2.5 hour with original wall charger.
That's way too long. Even from 0% shouldn't take you more than 2.5 hours.
Something is wrong with your wall charger.
fffuuuuuuuuuuu
i will try another one
I charge from ~20% to full in maybe 3 hours on USB.
Try charging from USB to see how long that takes.
I will take a few hours, maybe 4, to do a full charge from USB.
If it seems that it will take a good bit longer than that then it could be you cable.
i have another wall charger, and i will try from usb.
will take few days of testing
If you're using the HTC charger & cable plugged into a wall socket, you should be able to charge fully in about 2-3 hours, because the charger should pass 800-1000mA to the phone for much of the time, instead of the 500mA max from a PC USB socket.
It may be that the charger is (for some reason) not getting above 500mA: maybe it's the cable, or the phone is too hot or too cold.
Or perhaps the phone is running something quite hardware-intensive and soaking up half of the power that the charger is producing.
Have you tried running Battery Monitor Widget? It will give you an indication (a log too) of the input voltage and the power consumption over those seven hours.
For comparison, my Desire S runs at under 10mA when idle, and can charge from 25% in a couple of hours.
Might want to try charging when phone is off then.
ok, tried another charger, this one made 70% in less then 2 hours.
so the first one is ****ed, will recheck him maybe with usb-charging
Oh!!!
I always use the usb port on my laptop... So it is the reason...
Hi I just bought a used galaxy note 10.1
it did not come with a usb wall charger
after 7 hours of charging
a search said its my usb charger
I was wounding if it is normal for this to take over 24 hours from 0% battery on a charger like this
that only gives 0.5 A
or am I doing damage to my battery by leaving on charge for longer than 24 hours
its like a incredibly slow trickle charge
right now its almost full it claims but im not sure if it will ever be full at this rate
I thought maybe 24 hours but now its 1 hour past 24
I was trying to (calibrate the battery )
so I let it die to 0%
I turned the device on half way though charging
noticed it had an x though the batter so I freaked out and tryed plugging and unplugging it like 10 times
I was wounding how bad that might be for the memory of my battery to do something like that
because I unplugged it before it got to 100% when i was attempting to calibrate it
Im not sure how sensitive these batteries are
but your input would be much appreciated
You could use an off brand iPad charger with your USB cable to help it charge faster your typical phone charger will only give off 0.5 ma, so look for one for a tablet

to leave it plugged in now approaching 28 hours
the charging logo on the screen appears to have approximately 75% charge so far
I want it to get to 100%
should I unplug it if its not charged in 6-8 more hours
im mainly wondering if it is even possible to fully charge to 100%
on a old ipod usb charger or not

You are not harming your device. The only negative is that it will take longer to charge. The red is normal when not using either the correct type charging block or usb cable, it is not harming your tablet.
I would just do what some of the other posters have suggested, getting a new charger made for a tablet, just because waiting that long for it to charge is not practical.

SGN 10.1 GT-N80XX series need a specifically designed charger for them.
One thing for sure, it need to provide 2.1 A, 5 V & most phone charger only supply around 0.5 - 1 A.
Most 3rd party charger also only supply around 0.5 - 1 A.
The other is the data pin(s) & it quite different with Apple's charger.
I've tried several 3rd party chargers & Apple chargers (iPod,iPhone & iPad) & most of it unable to charge my N8000.
You need to buy an original charger for your device.
Or you can try buying 3rd Party N80XX charger on eBay from a reputable seller.
That being said, you also need an original cable to be used with the original charger.
Most 3rd party cable can only supply 0.5 A & some 3rd party charger can only be used using specific 3rd party cable.
A long 3rd party cable (10 ft / 3 m) usually can only supply around 1 A.
For example :
I have a Powerbank that uses its own cable to charge at 2.1A rate, but I can't use my own original cable with it
But my original cable is fine & I uses it to charge using my original wall charger.
It takes around 4-5 hours from 4% to 100% (with WiFi ON & all sync on)
0.5 A can't charge your device while in Power ON condition.
To charge at 0.5 A rate you have to turn OFF your device & it will take a long time to get 100%
(N80XX series have a 7000mAh battery so you can calculate how long).
NOTE:
The battery with red cross icon means that the charger/cable isn't designed for N80XX (usually the data pin settings is mismatching the original design), but it will still charge your device at a very low amperage (lower than 0.5A) to prevent damage for using inappropriate charger.

yes I will as soon as I can
thank you
I am still a little worried that It will never make it to 100% with the only one I have available for now
does not really sound like anyone has had the patience to let it go to full with this slow trickle
Amazon has the chargers and cables.

I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

I read somewhere that if you activate airplane mode the battery is charging faster.
XZ's battery charge time is 2.5 hour from 25%, is it normal?
I turned on battery care mode.
Battery care is turned on?
Mine also came with a slow charger. When I plug it to my portable battery, it can still be pretty fast (and hot...)
With stock UCH 12 charger it takes my phone about 1,5h to get fully charge. 30min to 60% and 1h for the rest. It seems like Sony disabled any type of QuickCharge above 60% to prevent battery damage and it doesnt matter what type of charger you would use alter that - it will stick to 1000mA all the time.
Two things:
1) are you using QuickCharge charger?
2) do you or any of your apps use phone while charging?
Any of those would prolong charging time.

Try to keep it turned on then. I guess Sony could set offline charging to minimal settings and control QuickCharge with software. Try "Ampere" app to check how many ampers are you getting while charging (download from play store, no root required). It should oscillate from 700mA to 2500mA. If not (e.g. stuck at 1000mA) it means your charger could be defective and should be exchange for new one.
man. I got 75% in an hour while the phone was off :/ using the same charger as yours so there must be a problem, try to change the cable
Guys does anyone know if the USB type-C cable which comes with the non-fast charger is 3.0 Quick Charge compatible?? I've ordered a Anker 3.0 Quick Charge charger just wanted to make sure the cable is.
My case is even worse, tales 3 hours to charge from 13% to 97%
I am even using the newest Sony 3A usb c to c quick charger!
What the hell..
XZ support QC 3.0 so it should be able to charge from 0%(theoretically) up to 100% 1h40-1h50 using a QC 3.0.
During my few weeks i've had this phone (recived with UCH20 charger) i tried to test phone's ability to charge quickly and failed it took usually 2-2h20 min with original charger. I've ordered chinese charger (sony's UCH12W is 4 times more expensive, even samsungs and htc chargers are much more cheaper).
During tests (using ampre) i tried to start charging when battery dropped to 10%. I used 2 charges original UCH20,Tronsmart WC1T and 3 USB-C cables 1x original, 1x unknown chinese, 1x tronsmart(original included with a charger).
Conclusion:
UCH20 is slower, Ampere won't show more than 1560mA 10-60/70% then something around 1100mA and 780 or less 90-100%
WC1T is faster, 10-60% 2220mA (or less depends on throttling/temperature) then about 1500mA to 90% and less than 1000mA (usually 500-800mA) 90-100%
Tested with onvo adaptive charging on, stamina off, wifi on, brightness auto (0-40%), there was no difference betwen cables only unknown chinese cable was slightly slower but that is only my opinion. Battery temperature oscylated between 26-37/38°C(Ampere)
This phone will only fast charge up to 60/70% then it slows down a bit and last 10% is slow, it should preserve battery health yet still allow you to charge it quickly when in a hurry so u can use it for another few hours until you'll get back home and plug it for a night.

Good post, thanks for sharing,
I ve recently brought Anker PowerPort+1 charger QC3.0 compatible and used stock Sony cable and max output I got was 2180mA max using Ampere too.. What my question is now what should the XZ be drawing max? near 3000mA?? Battery care Off.
Ive ordered PortaPow 20AWG cable it states its also QC3.0 compatible so lets see how much it get and if it makes any difference to the charge times.
I will post my results in the next 2 days.
