Why does Battery take eternity for some to charge? I think...

Like many of you guys, I have custom built my own PC. Yeah, it's a little outdated with a Q6600 but it will do for a good year or two more. Good thing I bought a Quad Core. But anyways, getting back to topic, you guys should realize that the Power Output of the front two USB ports are not the same as the USB ports that are in the back. This is a fact as far as my system is concerned. I know because I use a Lacie External drive which will only power on with the rear USB ports.
If you charge the SGS with the included wall charger, it will charge up in about 4 hours. When I leave it on my front USB port, I would wake up in the morning only to find it 60-70 percent full.
PS - I am amazed by the battery of this thing. Here is the break down. I fully charged by 1am. Took it off... then started using it quite a bit till around 3am ish. When I went to bed, the charge was at 72 percent. I work up 6 hours later and guess what, it was at 69 percent. Pretty neat.

The USB 2.0 only requires that a motherboard provides 150mA to a single port (& 500mA to 5 ports). Where as a chargers don't conform to this standard and provides a much higher charge, which charges your battery much quicker.

Only use USB if you have nothing esle.
The wall charger that came with the SGS is a 700mA. I just ordered a 1000mA wall and car charger.

The more I use this phone the more I am amazed by it. The Battery life on this thing is really great. It's already been close to 12 hours (11:30) and the battery is now finally at 49%
I've used this phone quite a bit and the battery held up really well. I used Let's Golf, Navigation, Armored Strike, Calls, Texts, Gmail... Good stuff.

So your telling me if i get a charger with more mA it will charge faster? Where can i get a bigger mA charger.

I don't know, but my battery charges fast as hell. It goes up about 5% in 20 minutes.

5% in 20mins, that's 15% per Hr, or 6.5 hrs from empty to full. You are happy with about 6.5 hrs for a full charge?

LOL , kids today are inept when it comes to arithmetic but cmon...

Aight more like 10% every 20 minutes, lol. I didn't know this was a math class, sorry. It is the summer you know -_________________________________-.

will it hurt the battery life or shorten the amount of time you can use the battery if you use a higher mA? because if it wont then why didnt Samsung just include a 1000mA charger with it?

It will do neither.
read this. Gives some basics on Li-ion batteries. link
Essentially these batts can and should be charged at 1C c=capacity. Our batts are 1500mA so we could and should charge at 1500mA.
Slower charging is fine but these batteries rely on circuitry recognizing a drop in voltage to turn the charge off, or down to a lower current as to not damage the battery. If you charge at a higher rate the drop in voltage is more obvious than with a lower voltage and harder to miss thus less chance of an overcharge and battery damage. Added bonus is the battery charges quicker
Over charging is the killer of batteries. Overcharge occurs more from circuitry missing a change in voltage and failing to terminate.
Hope this helps.

If you were an engineer and could save the company one cent, how would you do it? That was about one cent worth of cooper in the charger times ten million devices.you just made your year end bonus.
A dedicated chip inside the phone regulates the battery charge.

700 mA. See the info panel on the charger, it'll tell you.

So a charger with more mA will charge my phone faster i assume? I wont loose any battery capicaty right? It wil charge the same amount just faster i assume?

Very weird thing is happening, instead of charging my phone it drains it .
The battery icon moves back and forth as if it is charging but it drains my battery relativity fast.
5 mins using the car charger I lost 25% of battery life .
Does anyone know why this is happening ?

How...? I am on my third Vibrant and i last 6-7 hours...

Charges slooooow

So I am at a friend's house for a few days. For some reason my phone charges really slow here. I am using a aftermarket charger that works well at my house.
I put it on the charger at 9:30pm with 22% and woke up around 3am with 81%. I have incredikernel so it should charge fast... What's wrong?

depending on the charger it could output a very low voltage and making it take long to charge

He shouldn't need to do that for 2 reasons. 1. Fast charge is only on for USB, not AC/wall charging. 2. His phone only went up 60% in about 6 hours. Even on the stock rom and stock kernel, a FULL charge shouldn't take more than 4 hours. There is something wrong with the charger/the outlet/your friend's house.

I usually turn mine off in the evening while i eat and shower and it rockets to 100% in about an hour or so.
Maybe if you have a good hour or so that you know you wont be able to be reached on the phone, you can try that out.

It does. His point was that the FastCharge feature only speeds up USB (and some car chargers). Wall charging was already "fast" and can't be made faster by that feature.

Stock battery 1,300mAh... divided by 4.... 325mA... yep - I agree: any charger/ROM/kernel combo should easily be able to achieve a charging current of 325mA
OP's battery only increased 59% in 5.5 hours. Assuming a stock battery, that would be a charge rate of less than 140mA. That is flat out awful.
TheWhiteBandito said:

Agreed.
If the problem continues at other locations, I'd look to the charger first, then the battery second.
If the problem is resolved by charging at a new location, then the friend has some messed up wiring.

Another thought: is there any chance that the outlet you were using was connected to a wall switch somewhere? My thought is that maybe you plugged it in, it was charging, and then someone flipped the wall switch at some point.
Do your battery stats confirm that it was actually charging all night?

True, but no one here is talking about charging the phone in a few minutes. No one has even come close to mentioning dangerous charging speeds.
The charge rate of a typical consumer Li-ion battery is between 0.5 and 1C in Stage 1
Click to expand...
Click to collapse
Source: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
So for a stock battery of 1,300mAh, a charge rate of 0.5-1C would be 650-1,300mA
The OP's observation of 59% in 5.5 hours would be a charge rate of 0.11C
So yes, it's true to say that charging a li-ion too quickly is dangerous. But in this particular conversation, it's a moot point.
The OEM charger doesn't even put out enough current to achieve a 1C charge rate, and every aftermarket charger I've ever tried has delivered less current than the OEM charger. I'm not saying it couldn't happen, just that it's not likely.

Are you sure? I swear I remember Chad saying something about Fastcharge not working if the USB cant handle the output (which is why FastCharge is disabled by default unless you enable manually or flash Chads FastCharge Boot Enable Zip DooHickey). I would just ask him yourself, he's pretty responsive to the users of Incredikernal.

Not sure what you're trying to say. I already addressed the fast charge issue in this thread.
TheWhiteBandito is correct: fast charge does not affect wall charging speed.
Yes, Chad is very responsive, but why bother asking him something that he has repeatedly explained on the forums and on his own site?

This adds fast charging over USB to a stable release along with some potential performance enhancements.

i never bothered with an after market charge, mainly because i use the usb cord and the USB to A/C converter that was shipped with the phone.

GatorsUF,
So what was the ultimate root cause?

I'm not sure why you do this, Gator. It's not the first time. You ask for help, people offer what they can, and then you never say anything again. Is the problem resolved? We don't know. Did anyone in here offer you help? We don't know. Did you learn anything? Try anything? Even read half of the responses? We don't know.
Not only does this decrease the overall usefulness of the thread (since people have no idea whether the issue was resolved), but it discourages people from offering you help in the future.
"Oh look, Gator's got another problem. Eh.... I would respond... but that guy never even gets back to his own threads. I'll save my breath and move on to another topic."

Sorry
I am pretty certain it has to do with the power at the house. Not sure but I do know from working as an electrician that peoples household outlets are typically anywhere from 108v to 125v, maybe her house was on the lower end...
I had the same problem with the same charger at a hotels as well. However I am using it at home now and it charges like a champ at my house.
Could you please point out threads where I didn't respond with my result in the past, I will gladly fix those. However most of the thread I am finding include my eventual result. There is even a thread where I asked a question then made fun of myself and posted the lmgtfy.com link in the next reply, in turn giving anyone with a similar problem the answer I found.

Install battery monitor widget, it will give you the info you're looking for.

I installed that once and it showed some info about voltage coming into the phone but i wasn't sure what was good and what was bad...

Charging your Nexus 4 with an iPhone wallplug?

I've had the Nexus 4 for about 2 months now and it's really the best phone I've ever owned. But switching from an iPhone 4S, I can't help but realize how long charging takes. It's about 2 hours to a complete charge on an iPhone and almost 4 hours on a Nexus 4. I know the Nexus 4 has a battery that's a third bigger, but it shouldn't mean that it will take twice as long to charge.
I still have my iPhone wall plug lying around. Has anyone been brave enough to combine their Nexus 4 USB cable with an iPhone wall plug to see if it would charge faster? Or is there any charger that'll speed up the process (Samsung or HTC)? I haven't tried it yet I know Google and LG advise against using other chargers but I think it's worth a try especially if I need a quick charge before I go somewhere.
Side note: Previously, I did charge my iPhone using a iPad charger connected to a MacBook Pro extension. It would fully charge in about 90 minutes which was 30 minutes quick than usual and I did it often for almost a year without any problems.

Doesn't the iPhone wall charger have a rating of 1 Amp? The N4 charger has a higher rating of 1.2 Amps. Check and see.

Yeah, I've read that somewhere. But like always, numbers don't always reflect world world performance.
My N4's at full charge right now but I might give it a go tonight when it's empty. If anything, I would just expect the N4 to detect it as a USB source instead of an AC source.

It'll charge. That's not an issue. I'm just thinking it won't be any faster.

I've plugged my nexus into an iphone plug every day since I got it back in December (it takes up less space). The phone is fine, however, I wouldn't have a clue is it's faster or slower to load.

How long would you say it takes you to completely charge from 10% battery?

Yeah ive noticed it takes longer to charge then an iphone but im not to fussed.

I wouldn't do it... your phone might turn into an iPhone

I've been charging with iPhone charger and had no dramas either.
Any electrical appliance will try draw what it needs regardless of what's powering it.
eg. It's supply and demand - you've got a tap designed to fill a 2 litre bucket of water in 4 hrs filling a 3 litre bucket.
If you want good charge times grab a 10 watt/ 2amp charger.
But there isn't a problem with what you've got if the time issue isn't a factor for you.

The N4 only pulls about 700-800mA max. So a 1A charger is more than enough. But as has been said, it won't make it charge any faster unless there is something wrong with your stock charger.

Install Elixir and charge your device with iphone charger and then stock charger. In elixir you can see at what rate your battery charges(mA). compare both and you be the judge of it.
Peace.

4 hours? I'm lucky if mine takes 2. It only takes 4 on the cheap wireless charger I have.

I've always wondered, why do people get so concerned about using different wall plugs? Surely it's the phone that controls how fast it charges and how much it takes in? My family has 4 different ones (LG/Nexus, HTC, Samsung and iPad) and I've just used whichever one was free without issues. Please correct me if I'm wrong but I've just never actually worried about this and it worries me that so many people worry about it
Anyway to see which charges fastest use something like CurrentWidget which displays battery drain and charge in mA.

You are right, no worries with any usb charger. I've been charging my phone (N1, NS, GN, N4, Note 2) all using my old Sony Ericsson 700mA charger without any problem. Plug in before I go to sleep, then next morning it's full. Ready for whole day usage. Have been doing that for ages.

The iDevice chargers actually cut their output when charging a non iDevice. If you plug your phone in, sometimes you'll see Charging - USB instead of Charging - AC

I use my ipad charger, no issues but obviously I can't give input on charge time.
I stayed away from the stock charger since so many people had problems with it.

What about getting a higher amp wall plug say 2.1 amp at 5 watts and using FAST CHARGE?

Slowest Charging Phone I've Ever Used

I just got the HTC One and the phone itself is great. That being said, I have one pretty large complaint...I've never had a phone that charges slower than this in my life. Is anyone else experiencing brutally slow charging speeds? Probably take 5 minutes for it to charge 1% which means it would take over 8 hours to get to 100%. Is this really possible?

I know it helped with the old nickel cadmium batteries, but I've been under the impression that conditioning doesn't do anything with today's lithium ion batteries, that they are as good as they will get right out of the box.

Charge time Is a lot less than 8 hours normally. That said, it is still a slow charging phone compared to my previous few phones. However it is not too bad to be a complaint from me. We also have to be aware that the battery is a little bigger than the previous generation of phones, so it would take longer to charge anyway.

Yes this is using the supplied charger. Did a little searching online and it seems that there are others who have this issue. It was noted in the Anantech review as well as the following quote from the Droid Life review:
On a related note, the One takes forever to fully charge. I’m not sure why that is, but no matter what charger I seemed to grab when needing some juice, I found myself checking the status of the battery meter far more often than on other phones in my possession.

My phone needs about 4h to completely charge.

From Anandtech, the rationale is that Qualcomms fast charging is disabled in an effort to preserve the integrity of the battery's longevity; since you know, its sealed and has a repairability rating of 0. The Gs4 will probably crank that fast charge up and the user can replace the batteries as often as he deems necessary.

slow charging time seems a pretty fair trade off for a slow discharging time also right?

Maybe they designed it so that the user would be discouraged to fully charge the phone, and thus completing fewer cycles?
If it's just the last ten percent that takes such a long time, I'm not too worried about it. There are few situations during the day that I'd have to charge the phone to 100%, other than an overnight charge.

It's a pretty big batter, to start. But you're probably not getting much current to the phone. If you charge from the USB on a computer, you're hardly getting any current to the phone so it's going to charge very slowly.
The faster chargers are 2A chargers. I have a 2A car charger that came with my Nexus One car dock I've been using for a long time and it's the fastest charger I've seen out of all of them. All of my phones (and friends' phones) have charged must faster with that charger.
I have a 1.5A AC charger too. It's still not as fast as my 2A car charger, but I'm also inside at that point, so it doesn't matter. But most chargers I've seen are 1A or less. Those are slow.

It's not the battery you're conditioning. It's the battery stats on the phone. The phone needs to "get to know" the battery to accurately describe its status.

Charge time should be a tad under 4 hours on AC, so I would say something appears to be wrong. Unless of course you're doing something heavy on battery) gaming/navigation) during charging.

what scm_crash said. pick up a 2A charger if you really need juice fast, otherwise it's probably designed to simply charge overnight for longevity
I always use my nexus 7 charger (2A) when i need juice on the spot.

It's ridiculous that people here think that the HTC one is not reparable ,so HTC designed a phone that can't be open ? What if you break your screen ? So instead of repairing your screen and be charged 180 $€£ for example ,HTC will charge you 599 for a new phone cause the phone is unreparable? That's ridiculous.HTC made the phone,HTC knows how to open the phone ,HTC will put phone back together again period.

actually it's not comparable coz the volume of the battery aren't the same.
you can also check the charger's specs , a 2300mha battery charged by a 1A charger, that's approximately 2.7 hrs.
still, for the first time it took more than half an hour to charge from 99% to 100% and the LED to turn green, that was strange. probably because I deleted the battery stat file for calibration

Fast charging really is the killer feature of the note 4...

Cmon, lets give the credit where credit is due.
I no longer have to worry about battery charge thanks to this new fast charge thing. 45 mins after having a low battery I'm at 80%... thank god battery charging has finally progressed to this.
I use my phone for music / radio shows all day long. I can't tell you how happy I am to have this fast charge thing.. on the boat, in the car, at work at home, a 30 min charge and my phone is ready to go for HOURS!
Thank you to samsung and the note 4 for FINALLY putting a phone out there that is awesome!!

I agree but I rather swap my battery. When I get down to lets say 5% I don't have to worry about plugging it in. It takes less than a minute to go from 0% to 100% and it's less strain on the charging port and circuit. Plus if you still want to use the phone you don't have to be tethered to a cable.

+1 I love it. Swapping out the batter. LOL Not so much.

Battery swapping really sucks if you have a case on the phone. I vote for fast charging. Beautiful thing! I just need to get a fast car charger and I can charge my phone fully during my commute to work.

...and it's less strain on the charging port and circuit...

As an electrical engineer, seeing statements like this makes me cringe. I can absolutely assure you that there is no "strain" on the charging circuit, or battery, or anything else for that matter.
The only thing I could say is, possibly, the reduced battery life span due to the additional charge cycles. But charge cycles for modern Li-ion is already really high. But even if I were to entertain the fact that the battery might need to be replaced sooner, who cares. You are buying another battery NOW, vs the possibility of buying another battery in a year or so.
As far as personal preference goes, if a spare battery is your thing, go for it. But please try not to perpetuate the idea that the fast charging circuit or battery can't handle the charging.
I'm more than happy to go over the physics and electrical theory on how charging works. You might be interested to know that in a lab setting we can get charging rates as fast as 1 minute per 1000mAh with minimal heat build up (the major hurdle in improving charging rates)
Fast charging is nothing new. A similar concept are large capacitors, like a camera flash. They charge in seconds. The major engineering challenge is controlling the discharge rate, in most cases the heat build up is limiting factor.
Don't be surprised if the note 5 charges in 0 to 100 in less than 5 min.

Fast Charging + Killer battery life = One Happy Customer

i love everything about this post, btw. i'd love to know the physics and electrical theory if you ever want to share. it would probably help me to understand which is better for the phone, not that i need it right now, but i'm sure it would be beneficial to have that knowledge. i am one that is a fan of the fast charging, but i've also been looking at Samsung's spare battery charger too. the Korean Note 4 variants actually came WITH the spare battery charger (lucky ducks) but it's going for $45 ish right now on Samsung's website. might not be a bad investment at all, even though my battery life is averaging 12 - 15 hours on a singe charge.

This is true. I had an Energizer battery charger that could charge my AA or AAA batteries in 15 minutes. They got very hot though. This was in the 90's.

I had something like this as well. Mine had a fan on it that would attempt to keep things cool. I have an Ego lawn mower that can charge the HUGE battery pack that goes in it up by 50% in 15 minutes, and it sits on a big charging base with a huge, loud fan. That's a little different than charging a cell phone battery or AA/AAA batteries.
+1 on the fast charge thing. To me, that's revolutionary.

Fast charging is awesome, but I really don't use it. My battery life is so great the it easily lasts me the whole day with moderate usage. I usually end the day with 30+% left. The fast charging is an awesome feature, but i really have no use for it.

Someone was saying having fast charging checked depletes battery quicker. Ain't that some bs?

Has anyone given any numbers as to how slow / the rate of wireless charging is on this phone? I love fast charging but I want wireless charging as well.

I agree with a couple of these posts. I have moderate use on my phone and usually end the day at 40% or higher. However, I love having spare batteries that I can just pop in and be at 100%. Just ordered 3 plus wall charger for $20 shipped. Hard to beat having 3 full charges at hand if you don't have a chance to plug in for a while.
Battery life is great on this phone........period!!!

I believe most wireless chargers are 1 amp output. The stock wall charger is 2 amp so I'm guessing it would take about 2 1/2 to 3 1/2 hours to fully charge on wireless,I'm not expert though.

I do not doubt the usefulness of it, and I know it will come in handy some days. It's just my normals days I have battery to spare.
