Hey guys, yesterday i noticed something strange: it took 3+ hours to charge my S5 from 8% to 100%. I remember that it used to take around 2 hours at the very maximum from 0% to 100%. Then i remembered that my cable with which I'm charging is not the original one (it got cut long ago) but the charger itself is the original. Is something wrong with my battery? Is the charger bad? Should i search for an OEM usb cable? I don't mind it if it charges for longer as i charge it at night but still, this got me a bit worried that it can degrade my battery overall by keeping it hot for longer than needed. Thanks for any answers.

My phone gets hot when I use a non OEM cord as well. But its never hurt my phone. I've been doing it for probably a year now. As for the longer charge time is it suddenly taking longer with this cord or is it taking longer because you are now using the cord?

Well not sure as i mostly charge it at night. But my phone's battery life is normal while using it (atleast for now), just curious why it takes so long to charge.
Different cords have different capabilities depending how they were made. There's even some that only give power and no data transfer. Samsung makes fast charge technology for their devices. Other cords may or may not support it.

Hm, I always thought that fast charging is inside the charger itself and not the cord. Might get an official Samsung one then. Thanks for the info mate

It comes with the USB cord as well. And I'm pretty sure fast charge tech is both the handset and the charger itself. I read the charger is 1.5x faster then a normal one even if its not going to a device with fast charge and 2x faster if it is. I didn't mean to quote myself either. Lol

ok i switched to another phone and i stooped using nexus s for like 4 months i was planning to sell it and today i took it out it does not even turn on. does not take charge. it was perfectly fine... what happened?????
Maybe the battery got killed.
does it do anything when its plugged in?
pull the battery, put it back in, try charging, oddly enough sometimes works.
it was perfectly fine until you left it for another <del>woman</del> phone. how did you think it would react?
Try charging it connected to a computer. Often wall chargers can't charge a device that is completely dead

A charger is a charger. If both are working properly then one won't charge better than the other. One may charge faster than the other. Perhaps the battery has a dead or weak cell in it. Try swapping batteries with someone and see if your phone will charge it. Give someone your battery and see if their phone charges it. Try their charger on your phone. Try your charger on their phone. Process of elimination.

Think about it..why would one charge faster than the other? well because the one charging faster is being given more current. if the battery is dead and isnt able to charge with the weak charger, maybe the one giving out more current is just enough current to get it started. You can compare this to jump starting a dead car battery.

Yeah, no. It doesn't work like that at all.
Chances are the battery is just totally dead. If you have some sort of a charger that can charge any given Li-ion battery, hook it up and see if it charges. Otherwise, you're going to have to beg/borrow/steal/buy a new battery.
Yeah, a dead or weak cell is just that. I might be wrong but once that happens, there's no way to fix or revive it that will bring it back to normal. Check into it. If it turns out to be a bad battery, I'm not 100% sure so don't quote me, I thought I might have read the ns uses the same battery as the Samsung moment. If this is true, please research it first, then it shouldn't be very expensive to replace. I highly suggest you get an OEM original Samsung battery. Aftermarket usually never hold up as good as an OEM if both batteries are the same ratings. I've had OEM batteries outlast aftermarket ones for uptime even when the OEM was rated significantly lower in output. Example: I had sprint official battery that was extended 2200 for my evo. I had aftermarket 3300 for the epic. The evo would outlast the epic when both had a full overnight charge. Now before anyone says that's not a fair comparison, consider this. When both phones had OEM 1500ma batteries in them, the evo would ALWAYS die before the epic would. Noticeably sooner.
To full chagne the battery, need more than 10 hours. Tried different ROMs, Batteries, changers, cables. the same result.
It looks like a hardware issue...... but....
when I used a DC power supplier(5.2V, limit to 1A) and plug in the cable, it appears the DC current is 0.5A, and after 10 second, fall down to 0.1A. at least, in the first 10secend the hardware worked all right...
Do you use the original OEM charger ?
Have you tried a different charger ?
How old is your Note ? Have you tested a different battery too ?

I was quite surprised when I switched to the Note from the Dell Steak. My old phone would charge much quicker. The Note takes about six hours to fully charge I'd say. As a result I plug it in pretty much whenever I can.

Yeah, Mine can take around 5+ hours too if im charging it from <5%
Bear in mind that it is a bigger than normal battery, 2500mah.
But if it is like you say, Taking 10+hours to charge, Id get it looked at, Maybe send it off for repair or something.

Isn't it bad to constantly charge your phone even when it still has battery?
I heard it reduces the battery's life span.
I dont believe it is, I often charge mine even when its got plenty of juice left.
It may reduce life span, But the battery will live longer than the time you will own the phone so i guess it dont matter
No one can help. feel bad.
I saw sevral links saying same problem, but no solutions... poor us...

From what I've read, it's what you're supposed to do with the current generation of batteries. But then there's so much crap floating about about batteries it gets hard to figure out what is reliable info.
And this is with the original charger? If it's not an official charger, there's a big chance the phone will draw only what's usually allowed across USB. Which isn't much... In fact, with USB, the power draw of GPS/screen on/games can make your phone discharge even with the charger on. So try the official charger, on AC power.
Same problem...
I have the same problem.
At the beginning, about 3 months ago, my SGN works fine, battery are charged to 100% in 2 hours maximum.
I'm buy the phone from a Samsung Store, all accessories are originals. Today I send my phone to the technical assistance and there's no problem with battery or the charger.
My problem stars about 3 weeks, with an alert about different voltages after a full charge, the problem was solved only removing the battery and waiting an hour. At the technical assistance, the answer was to charge the phone when it's shutdown.
I already try that, format the cache, rebuild the system, everything using the ICS LQ3 from Baltic.

Is the problme solved after remove the battery for 1 hour?
paddyzou, the problem with the wrongs voltages, yes, my steps to solve this:
- Full discharge
- Shutdown of the phone
- Remove the battery for 1 hour
- Full charge with the phone hang out
The problem with the low charge I think that was okay, it's seen to be happen in random times, I just flash another LQ3(France) version of ICS yesterday and seems to be working fine.

This is correct, a chemical reaction takes place while the battery is discharging and is reversed when charging(changing). The chemistry of the battery changes how they hold energy. The Lithium ion batteries in our phones can be charged any time, they have no "memory" characteristics like previous rechargeable batteries (NiCd).
OP, it sounds like your charger is going. My stock HTC charger (2-3 years old) now only charges at about 40% the speed, which means the phone will discharge while its plugged in. I recommend grabbing one of those tiny square usb chargers (1A 5v, not 0.5A). I got one for like $6, as long as its 1A it will be quick.
Just wondering, how long does it take you guys to fully charge (From anything below 20% to 100%) your nexus 7? Because I've seen a few posts about battery related problems, and personally I think mine chargers slower than it should.
Also, when I use a wire to extend the charger, it's as if it wont charge, for it to fully charge i'd have to leave it on for hours without use, Since they're aren't any plugs where I'd usually sit to use it, I need to move somewhere else cause the wire is quite small.
For example, I've had it on charge since 2PM today, when I plugged it in it was at 14% battery, now (4:20 PM) it's at 63%. This has been without use, just sitting there charging. Plugged in via the charger and wire that come with it, to an extension with 3 other plugs in it.
I received my N7 with about 40% charge and it seemed like it took a really long time on that first full charge. It has been better since. I have heard if you are not using the original cable for the N7, it will dramatically increase the time it takes to charge and it won't show the charging icon. The supplied cable is USB 3 and your other cables are most likely USB 2. You might want to buy a 6 foot or 2 meter USB 3 cable for convenience. Also, use the original 2 amp charger it came with.

Well, that explains why the extender doesn't work, but I haven't been using that to charge it since I noticed it slowed it down allot. I've only been using the stuff it comes with ever since I noticed that. Still VERY slow though, it's only just reached 96% since starting charging it at 2am. so it's taken 5 hours to get from 14% to 96%, pretty sure this isn't right.
I've collected some data on N7 charging and cables issues here.

My completely drained N7 (<1%) takes approximately 3 hours and 49 minutes to completely charge it (N7 powered off during charging).

OEM charger and OEM cable.
How are those who've got their N10 finding the charging speed? Mine arrived yesterday and has been charging very slowly, as the reviews had said.
In six hours last night on charge whilst left on standby, it charged about 20%. Is everybody else finding a similar situation?
I'm looking forwards to the pogo-pin chargers/docks being released, which will hopefully charge a bit faster! If anybody knows how to hack something together to make use of the faster charging speed on the pogo connection then please do share! :good:
Of course, you have to look at the amperage and watt of your power supply. Even among the AC powered chargers, they vary greatly, and here you are talking about charging this behemoth with a measly powered USB.

If it takes 6 hours to charge 20% on a 2amp charger than that is seriously messed up.

Not messed up, just physics. There's an awful lot of resistance in a 9000MaH battery, and a standard microUSB (or even full-sized USB) connector can't handle the amperage that a faster charge would require. Which is why most big tablets had proprietary connectors up to this point.
But guess what? Google and Samsung knew this, it's why the N10 has one too, we just don't have the cable for it yet.
Pogo charger is coming, supposed to be at least twice as fast. Don't know why it was delayed, but most likely either a certification issue, or worry about Apple suing for it being too much like a Mag Safe connector.

Are the slow speeds people are getting from the wall charger our from a pc connection?
Are you saying a powered USB hub is charging it quicker than the mains charger supplied?
Thank you

I don't even charge phones via normal USB on PC anymore, let alone a tab. I've found the charging time on the N10 to be ok, provided the screen is off and also if I'm downloading something it seems to slow the charging down. Other than that it's not lightning fast, sure, but I'm ok with it. And so much the better when they release the pogo charger.
charged mine over night yesterday from 10% to full wall mains, but when the screen is one it doesn't seem to charge just maintains current charge which is a bit annoying

Try turning anything that uses power off (i.e)...turn the screen brightness the lowest it will go, turn the tablet on airplane mode. Turn the sounds off.
I find that helps my phone charge faster, maybe this will help with the tablet.
Are you talking about charging via USB on a PC, or via the PSU?
Through the PC will be very slow at a maximum of 500mA, but the PSU should be able to power it? My N7 and Galaxy Tab 10.1 had 2A chargers - what does the N10 come with?
I am regretring more and more buying this. I haven't received mine yet but the amount of pixels is kind of ridiculous. I would have been happy with 1920x1200 with that beasyly hardware. Saw a review that said their battery only lasted 4 hours because of the insane power the screen sucks away.
Also the fact that this pogo charger will probably cost $50+ and it is something that should have been standard either way.
Oh Asus infinity..why must your I/O be so god awful. You were almost the perfect tablet

Yeah charging is slow, though not as bad as 20% in 6 hours! I think mine was charging faster than that even when I was using it. I think trade off is worth it though with the microUSB connector.
The iPad 3/4 is no better... Takes forever to charge

It's nice to know that we have the Pogo pins option for faster charging. It makes me feel better now going through with my decision to get N10. I am a heavy media/game consumption guy so this device is perfect for my needs.

I must say I would hate to spend an extra $55 (assumed price) for a pogo charger for a tablet I've already spent $550 (tax+ship)
At first when I got my nexus 10, it was charging quite nice, overnight would charge from 30% to 100%, but recently it stopped doing so, for example tonight after 8 hours it got from 35% to 70%, all stock: same cable, same charger.
Also, sometimes I used to put it on charge while using it, like when watching video, and it used to charge even if slow, now when doing this it says charging but the battery level goes down....
can the stock charger or cable be damaged? why did it stop charging fast overtime?
I used the its usb cable and charger few times to charge my new OnePlus, which requires a high ampere charge, can this cause the charger to overwork and then damaging its power output?
I read about the pogo charger does the job better, but I also read about the 28/24 usb cables, and I guess that the stock cable is 28/28, they did it like this to sell pogo charger cables. but the main issue here is that with the same combination it was better a month ago....
I have multiple chargers around the house with various amperages that I use for all devices, except I do have a bit of fear using my oneplus chargers with others for your same reason
About a month ago we decided it was worth it to buy the pogo dock on eBay for our nexus ten so it can be used as a digital picture frame when not in use, great decision, it seems to charge faster than any of the other chargers and get to see pics of our newborn all day as well
Consider either this or buying a new cable/charger for much less money. Either way my best guess is this is what you need, but you can always try a factory reset or reflash stock to see if it is a software issue

Mine had the exact same problem after about 15 months use. Combine the slow charging with the atrocious battery life and you're left with a barely usable tablet. I later bought the pogo cable and switched chargers to no avail. Then I just said screw this and sold it.
My nexus is 3 months old, so it can't suffer from battery wear down in such little time.
Will try resetting the whole thing and try again....
