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?
Beamed from Maguro
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?
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

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!

I just got a t-mobile version of the S4 and I'm loving it, but I noticed it is very very slow to charge.
Aside from light to medium usage i didn't touch it much between last night and today. I had it plugged in and charging via USB, but it maybe charged about 40-45% in 6+ hours. My old phone (LG G2X) never took this long to charge.
More Info;
This was using the Stock T-mobile Rom
I have since rooted and installed CM10 nightly on the phone, It appears to suffer the same issue
Between 9:27 to 10:00 it went from 67% to %74, My LG went from %39 -%56 in about 20 minutes. By those quick number it will take 7 hours to charge the S4 while only 3 to fully charge the g2x
Is this normal? is there anything i can do to fix/test or alleviate this?

The question for you is the source? If you plugged it into your compy, it will take forever as standard compy USB ports (USB 2.0) provide only about 500 mA. The stock S4 charger is 2 Amps.
The fix, plug the phone into the wall using your stock charger. If it is still slow, it is probably your battery. Good luck.
Make sure to use the charger that it came with. Ever since I started using the stock charger my battery charges fast. Also it could be your plug so test it with another just in case.
Sent from my SGH-M919 using XDA Premium HD app
Yup it was the charger, I have chargers pretty much where ever i go so i just used those. With the stock one it works great but i ran into another issue. I plugged it in and it was taking a really long time to charge with the stock charger, something like 3% in 30 minutes. I had to unplug and plug in the cable again and it charged normally.
Is this something I should worry about?
It could be possible that the cable was not properly seated in the phone, or the charger end was not properly seated in the wall cube. I wouldn't lose sleep over it unless it happens often. Could be a phone problem, but sounds like a one off to me.
Yea my lady like to use my charger with her HTC phone because it "charges faster". The S4 stock charger has the highest amp rating and provides juice at the highest rate to any device. :good:

There are a few factors here.....
1. The charger itself. The original Samsung is a 2A charger. If you use a different one (most are only 1A) it will take twice as long to charge.
2. The USB Cable. Believe it or not, not all cables are the same. With the standard charger and cable you will be able to charge @ 1900mA. Less then 2 hours to fully charge a completely dead battery. But.... plugging some USB cables into the standard charger will limit the charge down to just 600mA.... taking 3x_ longer to charge.
3. The other is the kernel. If you're using a newer custom kernel Samsung has limited to a max of 1200mA with the screen on & full 1900mA with the screen off.
Lastly, you can download an app on the playstore called Galaxy Charging Current. This will show you the charging rate should you want to test your setup.

This man speaks the truth. I use CurrentWidget and set to manual update. Whenever I'm testing cables/chargers, I plug in a known good cable (charges at 1900) to see what the charger is putting out. I do the same with a known good charger (2A - iPad and S4) and test the cables

I feel the same about using the phone and charging when playing games. No idea how long it takes to charge it tho, doing it while i sleep anyway.
I'm going to go wireless charging but sometimes I'll turn my phone off and give it quick charge since it charges faster. I know some people don't like to do that though.
the first thing I would check is that the usb cable is plugged all the way into the mains charger. When I first got mine it kept saying usb charging is slow, please plug into a mains charger, which I thought was weird as it was plugged into the mains, but on closer inspection the cable wasn't all the way into the plug, so it was thinking it was using a pc connection. plugged it all the way in and it was charging like a demon then.
Same freaking problem. It discharges 100-0 in 6 or 7 hours, with 1:30 screen on time, and recharges 0-75 in three hours. Have you managed to fix it?

I've been using the GS4 charger, with a high output cable. The Samsung charger is 1.5A where the HTC m8/m9 charger is 1.0A
the supplied charger is definitely giving 1.5 amps to mine. charges up pretty quick. with a quickcharge 2.0 charger it's crazy fast to charge.
One thing to note is it will take a faster charge the lower the battery level is, which means more heat. if you're also gaming with it, you could be bumping against the battery charging cutoff temperature. I only ever saw this happen on my Tegra HOX+. IIRC HTC has the notification LED blink in alternating green and orange/red when this happens. I'm guessing you would have mentioned temperature in the OP if this was the case, but I figured I'd bring it up.

Just spread your arm, pick whether HTC M8 or M9 charger, and read upon it.. 8)
Both M8 and M9 chargers are - 1.5 Ampere.. furthermore both handhelds are charging fast - otherwise if the cable is a problem..

Sorry, meant it was 1.5a for HTC and 2.0a for the Samsung one. Didn't have them on hand to check.
iPhone 5 battery is 1,440 mAh... M9 battery is 2,840 mAh. 50% charge of Iphone battery doesn't equal 50% charge of M9 battery, in terms of charge time.
I believe the rate of charging to decrease while you use it to prevent the phone from overheating. (My M8 does this as well)
My stock charger is fast, and my quick charge 2.0 is crazy fast.

Yeah, this. I got an HTC Rapid Charger 2.0 for it just to be sure since I knew with certainty it's Quick Charge 2.0. In retrospect perhaps not the best move considering I'm essentially incentivising HTC for not including one in the box from the get go, but whatever.

Yup i got the same issue gonna take me 6-11hrs to charge and its very slow charging
I had a similar problem to OP. The second night I had my phone I plugged it in at 11 pm with about 5% battery left and went to bed. At 5:15 the next morning (6 hours later) it was only at 85%. I can't tell if there's still a problem or I just think there is because I'm paranoid about it now. I haven't run my battery down that low since, and looking at the charge current with Ampere seems somewhat inconclusive. I may have to run it down and then keep an eye on it while charging to see what's going on.
Something IS wrong with SOME M9 phones (I think)
I have one of the "bad" ones. Mine takes hours and hours to charge, whether on the cable and plug that came in the box, or on any others that I have around - some I know are 2 Amps. I think there is something seriously wrong with some of these phones, based on what I am reading in this thread, and on my own example. I have had my M9 for just a few days.
I'd like to post a follow up to this thread after having the phone for a couple of weeks now.
I've had several occurrences where my phone didn't fully charge overnight. The worst was a few days ago, I plugged it in at 5% and the next morning (6-8 hours) it was at 1%, it actually lost charge. I noticed before unplugging it so I looked at the history in Battery Widget Reborn and it showed the battery level just slowly dropped from 5% to 1% without any jumps or dips. The battery icon at the top of the screen showed it was charging but it died at that point so I didn't get a chance to open Ampere.
I think it's the charger (and/or the cable) that came with the phone. I've tried several other chargers that have all worked reliably:
- The QuickCharge 2.0 charger that came with my wife's S6 charges my phone really fast.
- I have a Kmashi external battery that also seems to charge it relatively quickly.
- Two older chargers that are several years old (both rated 5 volts at 0.7 amps) charge it from around 30% to full in 3-5 hours.
At first I thought it might have been a wakelock problem, but the battery has been dropping so slowly when the phone is just sitting in my pocket that I'm confident now that it's not wakelocks. I don't know if HTC is likely to send a replacement, but I'm going to stop into the Verizon store that I got the phone from to see if they'll replace it.

My phone is also odd when charging.
Half of the time it takes 6 hours or more to charge. If I look at GSAM battery monitor it shows a charge current of around 350mA. If I then unplug the charger and reconnect after 15 seconds I get over 1300mA charging current, most of the time. (It takes GSAM a while to show an accurate reading). Occasionally it will take a few tries to get it right. Once I get a good reading over 1300mA the phone will charge in 1.5 hours like it should.
Something very buggy about this phone's charging circuit. I get the same behaviour with all chargers and cables, even my battery bank.

Anyone else notice that with the supplied charger charging ins't what it should be. My iPhone 5 charged almost twice as fast as this phone. I find it kind of annoying. I did order one of these chargers hoping that solves the issue.

I use a 2A tablet charger from my hp touchpad. Charges from dead to 100% in 45 minutes.
