Anyone else having problems with extremely slow charging?

When I first got this phone I noticed it charged pretty slow. 5 hours to get to full from 0% but it then got a lot worse. Over night it would only charge from like 18% to 41 so I got a new charger and wall adapter and that seemed to fix it for a couple days but now it is charging slow again. From 70% to 100 it takes about 6-7 hours. Anyone else experiencing this?

The only time I've heard of that happening is when people fail to 'condition' their lithium battery properly before normal use.
In other words, upon getting your new phone, and/or battery, you're suppose to allow your battery to fully discharge and then fully recharge 3-5 times to condition your battery before plugging it back in half way through discharge.
It's usually what the carrier sales clerks are suppose to tell you when purchasing a new smartphone.
Here's a simple article on the subject:

I never had/has/have doing it. And I dont have battery issues.
I think the battery calibration/cycle..etc is just a myth.
Go to the store and check for warranty.

Could it be a rouge app causing it to take so long to charge? I noticed today Google maps was using a lot more of the battery than usual. Almost as much as the screen. I tried force stopping but it just starts right back up again. Any ideas on how to fix the maps app? I have a feeling that is what is causing it.

I have this problem. It is very annoying and I have no idea what causes it. It doesn't happen all of the time though.

Just sounds like a bad install of something. I would do a factory reset through the stock recovery, and make sure to wipe dalvik cache.

My phone has started charging slowed as well, but mostly when connected to the computer. I made sure my usb ports were set to not allow the computer to shut them off to conserve power and it seems a bit faster. As far as charging and discharging ect ect I don't do that and never had a problem with slow charging and even the couple of times I tried it, the battery life never really improved. So think it is needed and some think it is a waste of time.

Charging via a computer USB port will always be slow when compared to the higher current capacity of the included AC charger. Computer USB ports have a lower current rating.
Make sure your using the charger that came with the phone, not all chargers are created equally.
There's also been some talk about the quality of USB cable being used, but I haven't found that myself yet.

Little bit of info...
I have tried numerous chargers while at work here (Technician) and there are some issues.
Samsung is funny on which chargers it accepts. Very funny.
1. Stardard charger that comes with the device will charge best. (Obvious I know) Using wall charger. (Full charge in 3.5 to 4 hours from 1%)
a. Using USB end plugged into PC while charging takes typically from my tests double the time to charge. (I'm guessing that data connection to PC is slowing the charge. (Full charge in 6 hours from 1%)
2. 3rd Party Generic charge cables (usb cable only) still charges device however stardard power draw is lower and does not charge in a decent time period.
a. Some 3rd Party usb cables plugged into a pc showed charging however they did not keep enough of a draw to actually charge my phone. I lost battery instead of gaining.
3. LG chargers did nothing for me. Couldn't get a decent charge.
Motorola chargers gave me the best charge besides the original.
Chargers with replacement tips... what can I say. They didn't seem like a good idea and weren't. I had too many issues and at times had some overheating issues. Luck of the draw me thinks.
3rd party wall chargers were hit or miss. A few did seem to give me a decent charge, others gave me a very slow trickle charge taking anywhere up to 8-9 hours for a full charge from 1%
All in all... it's a crap shoot using 3rd party cables. It's all based on voltage output and Samsung likes to change things alot. You will still get a charge but who knows the length of time it will take.
Oh and car chargers... typically only good for keeping it at the same level you plugged it in at for short drives. Long drives obviously work much better.
Hope this helps.

About charging: I have noticed that micro USB cable that come with S3 is really bad - it is loosing a connection to PC,and, beside that, I have noticed several times slow phone charge... Accidentally went to settings- battery - when I was on AC charger and saw in settings that phone is actually charging in USB mode!!! Wtf??? Disconnect usb from bottom end (at charger side) and reconnect and then on phone says " charging - AC" ... So,conclusion is that you check your phone charging status when you put on charger,maybe it is charging in USB mode and because of that phone is charging slower than it should on regular AC power.

The only battery issue that i have noticed is when i use my computer to charge it takes forever but when i use the factory wall plug and cable it charges quickly with no issues

Excellent post supercholo. Really helpful. I was starting to think my phone was broken.
Anyone got any experience with using an ipad charger on an sIII. I know an ipad wants a lot of power to charge.
FYI These are the voltages listed on my chargers;
Apple ipad1 charger 5.1v 2.1a
SAMSUNG s3 wall charger 5v 1a
Samsung Galaxy i9000 wall charge 5v .7a

Very slow charging with OEM charger.. i9300
This is a fact. The OEM wall charger surely has some issues. Though 1amp output, as claimed on th specs chart, my i9300 charges super slow. From 80% to 100%, it takes nearly 3 hours.
So, i switched chargers and used my S2 and Note OEM wall chargers. And voila, the phone charges super fast. I even ordered a new OEM charger for s3 with the data cable included and the same issue occured.
This has worsened ever since the JB update. So I am now using the S2 charger and very satisfied.
SWTICH OVER GUYS!! OEM charger is useless,,,

I have had my phone on USB to computer charging for 7 hours, with a one hour break to watch Dexter. I was at 18% and I am now at 69%. I think I will have to use the wall adapter because this is just ridiculous.

Usb to pc will always be slow buddy. It outputs 500ma while d wall charger is 1 amp
I found my Usb cable faulty. Sent for replacement.

Without reading all the post. I have had this same problem. Took phone to sprint, they tested the battery and it was bad. Got a new one and good to go..

[Q] Battery charging too slow!?!?!

Charging time for my battery is pretty slow. I takes more than 3 hours from 10% to full! It doesn't matter if it is chraging with the carger or via USB. Is this normal with the Nexus? I had Htc Inspire 4G, and the charging took 2 hours top!
*if i use the phone while charging e.g. play some game, the battery is still draining instead of charging.

You should get better results with an A/C charger but I've seen some wall adapters still read as if its plugged in via USB. You can check by going to settings >> battery while it's plugged in and it should read A/C charging.

What is the max current (mA) the charger you use can provide? Divide the capacity of your battery (in mAh) by the charge current. That is your approximate charge time in hours. I believe most AC chargers can charge with 1A, so a stock GSM battery of 1750 mAh should take less than 2 hours from being discharged to fully charged. Mine does.
The behavior that the GNEX will discharge even while being charged with a non AC charger (including car chargers) when gaming/navigating is not uncommon.

Yes, it's reading A/C charging, but the charger is from alcatel with 400mAh output.

I've been charging it with Alcatel charger with 400mAh output. I'll try with Samsung charger with 5.0V output which says it's equal to 0.7A because I don't have the original (I think i have used it before, but i dont recall that it was any faster).
Could be kernel related issue, since there is an option to "Fast charge" via USB and it's enabled?

its not likely a kernel issue unless you are on some experimental one, but you would be able to easily find out by looking at the forum cause others would have the issue. And if you didn't know the Fast Charge option is to make your phone think its hooked up to a wall port if you are charging from your laptop or if your car charger is only being used a usb port thing.

It's franco kernel, nightly 251, pretty stable from what i've read in the thread. Also, I know what does Fast Charge option do, but I thought that somehow it messed something up. While I was googling for answers, I found some forum, where was mentioned the battery chip that is regulating the power it's using to charge the battery could somehow get messed up. Maybe I have bad batt.

mine battery too takes 3 hours to full charge using stock samsung wall charger. I'm using stock rom and kernel.

Mines takes 1 hr 30 minutes tops with fast charge

You are using a 400mA charger, the gnex comes with a 1A one. Go figure.

That is because the car charger most likely did not short both the data pins out, therefore you notice the discharging phenomenon because the phone will only take in 500mA without the data pins shorted or with kernel fast charge enabled. How is 500mA going to keep up with navigation, GPS and all other tasks?

Also realize that your previous phones battery probably had a lower capacity than the gnex therefore coming from 2 hours, 3 hours isn't that bad for charging a bigger battery

As has been stated get a GOOD quality charger. I might be weird but both my car charger and spare outlet charger came from Verizon. At least when i have had something not work they have been more than happy to open another and fully test in store for however long it takes. Sadly, my last car charger broke and I am too lazy to get another, my solution was to use a car inverter since I charge my other devices regularly on long trips. Plugging in a regular wall outlet from, oddly enough Motorola, does the job just fine. Alas, the majority of chargers my coworkers leave out are for lesser phones and will not even register on my beastly Nexus.

However i think i damaged my charger (original 1Ampere samsung wall charger) when i've been in Malta (i'm from Italy) last August. Before the holyday my nexus charged in 2 hours or less. During the holyday the charger heated a lot more than when using at home and now the charging process lasts about 3 hours. Also, when i connect the charger to the wall (even if the phone is unplugged) i hear a low almost-ultrasonic whistle.
I hope the damage isn't the battery.

Thank you very much. And the effective result is really a faster charging? Does it works good or not?

Does charging take a long time for anyone else?

I went to sleep last night with the battery at 15%, slept for ~5 hours, woke up, and the battery was only at 50%. Is this normal? Does it take this long to charge for anyone else?
For reference I'm using an HTC charger from a previous Android phone, would using the Samsung charger make a difference?

Yes it seems like too long for too little of a charge. Give the Samsung one a shot.

Your using a charger that at very best pumps out 1amp
The default note 2 charger pumps out 2amps
In other words your charger will take twice as long as it should to charge your phone

If you use note 2 charger,than it can charge to full within 2 1/2 hours.

I agree, the Samsung charger with its 2A is necessary for this large battery if you want it to charge fast.

It's from a HTC wall charger. I changed it to the Samsung charger that came with the phone. Will let you guys know how it goes when I go to sleep tonight.
Will the USB cable make a difference? I have a super long USB cable that I like to use instead of the short default cable that came with the phone.

I know about the 1 Amp / 2 Amp charger ratings, but unlike the original post:
I have my Motorola Xoom 10.1 plugged into the wall, and i use a USB OTG cable from the Xoom to charge my Note 2 overnight (so to only use 1 plug socket).
So i assume this is providing 1 Amp or even less to my Note 2.
I often have it charge my Note 2 from 5% or less all the way to 100% in under the 6/7 hours sleep i get.
Somehow the original posters 35% charge in 5 Hours seems very slow.

with my Samsung box set usb cable, it still takes 8 hrs to charge 100%. sometimes the red led is on but without a single percent charge. I am talking about charging with the usb connected to the laptop. if plugged in power, it takes less that 3 hrs for a full charge.
I remember my previous win7 was perfect, may be the new win8 is having some problem or not, I don't know?

My Xoom must give out some good Amperage if i can get a 100% charge in 6/7 hours then.

The "only" thing that matters is the voltage.
The included charger puts out 5V(+-5%) and 2A.
Too little voltage, and it won't charge.
Too much voltage and you will burn a fuse or the charging circuits in either the phone or the charger.
The phone chargers (no matter what brand it is) are within the limits, so don't worry.
The current (Ampere) shows how much power your charger can deliver at a given time, but the phone itself decides how much current it can take.
A standard USB-port (1.1) gives out 5V and 500mA.
I've built LED cables based on this.
USB 2.0 and higher are supposed to be able to give up to 1500mA under certain circumstances.
My motherboard has a pair of special USB-ports which can recognize cameras, phones, etc. and charge with a higher current and even without having the computer turned on.

While charging through USB-ports a full charge takes ages for me, 6 hours while sleeping will never even charge close to 100%.
On the other hand, charging though the adaptor that came with it or any other adaptor that can pump some juice is blazing fast... 3-4 hours and it's back to a 100%.

Okay, this will sound too silly but this worked for me! Encountered and suffered from the same problem..
It used to take 8 hours to get fully charged...but in time i noticed this silly and weird thing...should work though..
Before putting the phonw on charging, kill all running apps...then when you plug the charger-DO NOT TURN THE SCREEN OFF BY YOURSELF...let it sleep automatically. And it'd get charged lighting fast...it worked for me!

If i put my Note 2 on charge where its at 25% battery, in 30 mins my battery gets charged to $85%! And you should ALWAYS use the charger that comes with your phone instead of a charger made for another phone. The HTC charger is designed to charge that HTC Phones battery. Each charger is different in the sense it provides different amounts of power. The Note 2 battery is huge so the Note 2 charger is designed to push a specific amount of power to it to charge it in a reasonable time.
For e.g. If you use the iPhone 4 charger to charge an iPad, in 5 hours it will charge the iPad to approx 50%, and if you use the original charger to charge the iPad the iPad will be more than fully charged. Thats because the iPad charger is designed to accommodate the huge battery inside the iPad.
Also i read an article not too long ago that said that alot of science goes behind these smartphone / tablet chargers and how its dangerous for the charger and device / battery if you start mixing and matching chargers.
My $.02 cents!

[Q] Charging issues - CM10.1

I currently have the CM10.1-M3 build from 4/17/13 installed.
For a long while, I have been having major issues charging my Captivate Glide.
My original battery died. It was bloated. I called AT+T and they sent me a replacement. I also bought two high capacity batteries.
If I leave the phone charging about half the time little or no progress is made charging. Lat night I charged the phone for over 8 hours and the charge went from 10% to 14%.
Other times I will wake up after charging it all night and it will say fully charged, but then the instant it is unplugged from the charger, it will drop down from 100% to 20% or less.
Then once every 3 or 4 days it will actually fully charge. But even in that case the charging is slow at best.
I did a full wipe and re-flashed last night and nothing changed. I have tried charging in airplane mode, but that seems to make it worse. I have had a little tiny bit of success turning mobile data off, but otherwise I have tried everything I could think of with no luck.
Has anyone else experienced similar issues, or have any suggestions? Is this a case where I might need to replace the phone entirely?

I have tried a few different chargers. I mostly use a 2.1amp wall charger. I also have a 1 amp wall charger, and a 1 amp car charger. I have tried about 3 different car chargers.
I am really suspicious that the micro-usb port on the phone went bad and that I will need to get the phone replaced.

Charging with AC is gonna be alot faster then with DC. But as far as it being the rom I don't see tthat.. sounds like possibly a loose wire or bad connection when u lay ur phone down

Charging
Hello,
When I charge my Captivate Glide with phone powered up plugged in to the wall, using the supplied wall charger, I've noticed that the battery seems to drain quicker. This is with the original battery, I will be getting an extended battery for my phone. If I power the phone down then charge it in to the wall it charges quickly and seems to take longer draining. This does not happen when charging with the PC.

Bloated battery could just be bad - but it could also be due to overcharging. That's not going to happen unless there is a serious problem with your phone, or possibly a problem with the contacts leading to an incorrect voltage reading. This also may explain your problems charging and sudden jumps in charge %.
Clean your contacts well on the battery side and phone side with a pencil eraser, rubbing alcohol, etc.
I notice a big difference with whatever kernel is shipping with the current M3 cm10.1 build between a 500ma charger and 2amp charger, so I imagine the kernel is set for a 750ma or 1amp charge.

10 hours to recharge phone ??????????

Can anyone tell me why it takes so long to recharge my phone ?
I use a charger cable from my computer (usb) to phone while at work --- then I also use it at home too.
Is it only the wall charger that does it fast ? not USB/laptop/computer ?
Last night it took me 10 hours (phone was on but I didn't touch it for 10 hours - internet/wifi/3g was OFF)
why does it take 10 hours ?
Is something wrong with the phone? battery? or is it the charger ?

USB only has a small amount of current that goes through it. Enough to power small USB devices and no more. I believe it's around 500mAH. But your phone is always drawing power, so the excess is what actually charges your battery. Your wall charger is 1000mAH which means there is plenty of current to charge your battery even with heavy usage.
Tl;dr: USB is weak and 10hrs is normal. Wall charger is much more powerful and faster.

damn thanks for the great reply.
Further more, I was at my friends house once, and he has a black berry (same charger as my SGS3) and he passed me this cord to charge and it honestly charged the entire phone from 5% to 90% in like less than an hour...
not sure wtf this was but is it possible ? is it bad for the phone ? for the battery ?

10 hours is not normal. And the average wall charger that comes with your phone is 750mAH, not 1000. The 1000mAH chargers are quick charge ones.
The fact that the blackberry charger worked well on your S3 tells me that you should get a new charger.

where does one find one of the quick chargers to buy ? (1000mAH)

you can find all sorts of chargers on amazon. you can find inexpensive ones at walmart too. i would recommend buying a samsung charger for your samsung phone. hold onto the one that came with your S3, even if it takes forever to charge. just use it to connect to your pc for file transferring, odin, etc.

Even though charging quickly seems good but if you can afford the time then use the one you already have z charging too quickly affects your battery health negatively , a slow charger will make sure your battery stays healthy for a long time , mind it by slow I mean a 750 mAH one not a faulty one in case yours is faulty .

The S3 charger is 1000mAH. I have two of them that came with my phones. And anytime I connect my phone to my computer I can leave it connected for hours and only charge a few percent. This phone just draws a lot of power.

thats interesting because i have 4 samsung chargers. 2 came with my old S2's and 2 came with my 2 S3's. the output on all 4 is 700mAH. i got robbed. of course, connected to a PC the output is max 500. even at that, i still get a better charge than a few percent when connected to a PC for hours.
