Does anybody else get super SLOW performance when charging?

Whenver I'm charging via wall charger or USB my captivate is super duper SLOOOWWW. It takes forever to switch screens, the keyboard doesn't function correctly, and my bluetooth won't sync. As soon as I disconnect the charge everything is back to normal.
Any ideas?

No replies? Sooo...Am I the ONLY one?

be patient for answers here
Ive noticed it charges slowly but I have not noticed it being slow while charging.
The theoretical output of the charger is .7 amps, and thats not very much in the smartphone world these days. When I am using it and it is plugged in, it charges roughly a percent every eight minutes. The .7 amps must be just enough to cover the phone being on and in use.
I am currently looking around for chargers in the 1 amp range. My old tilt 2 charger works great for that and i definitely saw a charge time improvement. I would love to have one with a greater than 1amp output but I dont think you can find them anywhere

Are you running SetCPU with set profiles ?
If Yes : that is the problem , adjust profile.
If Not : must be something else, not a common behavior.

I read this on another forum but someone mentioned changing the default usb setting from Kies to something something else may help.

No, mine doesnt do that. It runs the same whether its plugged into the wall charger or not.

As long as the output is 5 volts, you're o.k.

My captivate runs the same while charging but the actual process of charging the phone takes forever it seems. I've only had it a couple days now and I have to get used to killing some tasks while charging because I actually think the battery life was decreasing as it charged.
Incidentally, the display is the real killer on the battery...most tasks don't really eat as much battery life in comparison.

Recent Nokia chargers will work with a slight mod to the plug where it fits the phone,

After Pimping out my phone it works fine while charging now. Yea screen eats up like 82% of batteries resources...OUCH!

Just search for Motorola P513 on Amazon. Rapid rate car charger! And, belive me, it's perfect fit! Now on sale for $5.85 (was $29.99).

I agree with the device charging slowly (but then again it doesn't help that I'm using it while it charges) but I have not had any performance issues.
Sent from my Samsung Galaxy S

for those of you who have a old iphone/ipod touch charger block, use that instead.
its rated for 5V/1A output, higher than the 5V/.7A output on the default samsung charging block.
that should charge the phone much faster

I have the same issue with charging, no matter what charger I use (iPhone, Tilt, USB), it's all VERY painfully slow. I've been as high as 1% per 6 minutes (rare - when using Nokia charger (1.2A I believe) to 1% per 13 minutes via USB.
I'm thinking it might be something internal to the actual phone. The iPhone didn't take this long even with USB charging through a computer or LCD monitor. Heck, the iPhone on average was 90 seconds per 1% of battery. I could have a nearly dead phone and be fully charged and ready in less than an hour and a half.
Anyone else think the same?

yea i think it might be something related to the phone indeed. this is, in my opinion, the biggest problem. i'm always on the go and i depend on my phone so much that if it doesn't charge fast enough i'm screwed.
let me make a post in the galaxy s forum and see if there's battery charging problems

Everyone else is charging.

which thread is that? I'm curious to track that one as well. I have gotten 4 other people to purchase the Captivate from the iPhone and we are all on the same boat..even with a 1.2A charger from my N97 (which only lasted 3 weeks with me...but can't wait for the N8), it takes about 4 hours to charge the battery...something's wrong there. It shouldn't take less to drain the battery than to charge it!

Where's the high current POGO charger?

For cryin' out loud, I'm tired of watching my battery drain while plugged into the supplied USB charger. It's ridiculous. I've never owned a portable device that discharged under normal use when plugged into its supplied AC adapter. If I want to spend 15 hours a day playing Angry Birds, it should be possible when I have a power source which is virtually unlimited. Twice, I've started the day with a full battery, had the device plugged in to the supplied 2 amp charger all day, and had <10% left on the battery when I went to bed. (No, I don't actually play Angry Birds for more than a few minutes at a time but I do use the device a lot.)

I don't have that problem. You do know that your device will wait till it drops some percentage before it starts charging again. It won't keep it at 100% the whole time... Is meant to conserve your battery life

Let's pretend I've got just a little experience with portable devices. The standard is to float between 95 and 100% charge and just call it "charged" once it's bounced off 100% the first time.
Here's a test you can do that requires no time on your part. Set it up to play a long movie while it's plugged in. Look at the charge level after it's been going for a couple of hours. And you don't have to take my word for it. I'm hardly the only person complaining that the supplied charger is not capable of keeping up with the device's power requirements.

If you are seeing power drop during normal use while plugged in I'd talk to Google. You may have a defective unit. Mine doesn't do that and I regularly see 20+ hour days with normal use unplugged and usually with some video, browsing, games etc.
Take note off when you see the drop, how much you lose over a given amount off time and call Google and see if this is expected. I'm sure they will help. They have been very responsive when I've called.

I will watch like 1 hour of Streaming Vid's and loose like 4-5% while plugged in.

100% brightness causes my device to use more power then what's being supplied from the wall charger, and a few other people have confirmed similar incidents as well.
Max your brightness, and then go play a 3D game, while being plugged into the wall charger, and watch the percentage drop still

My tablet lasts a few days at least before needing a charge. I plug it in over night and it charges to full. I couldn't be more happier with it considering it is not self-sufficient.

Mine drops a few % per hour in use with the stock charger connected. Brightness at 50%, WiFi on, BT off. I'm not going to whine about it, but its the only thing that's not great with this tab.

Why do everyone seems to think that the POGO-charger would be able to charge the Nexus faster?
I've read on an Ipad forum that about 10-15 hours charging are normal (the Ipad 4 has a 42,5Wh battery), and their chargers give as much Watt as our Nexus chargers.
One thing is clear, you can't increase the voltage. That would kill your Nexus right away.
My Samsung charger I recieved with my Nexus 10 says 5V out and 2A.
5*2= 10W.
Isn't that the same rates that other tabs have, even if they got special chargers?
So, the only thing the POGO-charger could raise, is the amount of current.
Even if you had a 10A charger, if the Nexus cant use more than 2A, it wouldn't get anymore amps than 2.
If the kernel on the Nexus doesn't support any higher charger rates, then you cant change anything.
There is a reason why the manufacturers have set 5V as standard - to make it work together with USB.
Battery Specs: Samsung Li-Ion 3.75V 22.75Wh 9000 mah.
So, it's easy. If you had a 1W charger, it would take 22,75 hours to get a fully charged battery.
In theory, it should take 2,75 hours to fully charge the Nexus 10 battery, but we don't turn it off, we use it while charging, it uses background sync and I dont know what the efficiency rating is on the charger or the Nexus.
You know you could feel some heat on the back of the Nexus 10 after some usage?
That's some of the battery's energy that spoils into heat, meaning that there are power losses.
It's normal though, we don't have anything yet on earth that could convert 100% energy from one form to another.
You could compare it to a car, you need a cooler-system to remove the excessive heat from the engine.
Even if your Nexus is far more efficient.

Please do not speculate about how much current can go through the pogo connection. Speculation is worthless and helps nobody. The fact that the included charger only puts out 2 amps probably has to do with limitations of the USB connection. But I'm speculating. See how pointless that is? The fact that one connection is limited to 2 amps doesn't mean all power connections are limited to 2 amps.
And where did I say anything about increasing the voltage? I'm not an idiot and didn't suggest such a stupid thing.
As for temperature, that can easily be monitored during charging and the current can be reduced if it gets too high. You are aware that there is a temperature sensor for the battery, right?
None of which has a darn thing to do with my opinion that it's unacceptable to produce a device that uses more power than it can get from its AC adapter. If there really is no way to run the Nexus 10 at full tilt without supplementing the AC adapter with battery power, Samsung should have addressed that problem before going into production with this unit. This isn't a $150 entry level device. It's the Android flagship.

Please, you started speculating about a high-current POGO-charger that doesn't exist.
Sure, you didn't mention the voltage, but I ve seen comments about it before, so I just wanted to make it clear.
And I didn't say the temperature was a problem either, just that it lowers the efficiency of the charger and the device.
Samsung maybe didn't know there was a charging problem.
We've seen examples before that manufacturers don't test their products enough.
(ASUS Transformer with encased aluminum body, anyone?)
And I know, this is supposed to be a flagship, but what everyone forgets is that it's much cheaper than other brands.
I was looking forward to buy a ASUS TF700 with keyboard at almost twice the price as the Nexus 10 before I read about the Nexus.
Even if it doesn't justify the charging problem, you could try to adapt to the circumstances until there's a solution.
When I'm low on battery, I let the device charge and do something else for a change.

I have a nexus 10, nexus7, and a Tf700. I am noticing slightly faster charging on the n10 using the Tf700 ac adapter. The same is true when trying to charge my tf700. The stock samsung n10 ac adapter charges it slower than the asus transformer adapter. The same is true with my nexus 7 adapter. Ive used the n7 adapter to charge my tf700 and it was not as quick a charge. Meanwhile all 3 units are rated for 5v 2amp.

Could be possible the N10 charger isn't actually putting out 2A? Might need a multimeter or something to verify for sure though...

I am currently out of town so keep in mind I didn't have a chance to dig too deep but I've given the kernel a quick look through.
There is no such thing as the "high current pogo charger." The pogo pins accept 2A max and appears to be ~5V. The USB connector has the same limits.
I also took a look at the current at the battery to make sure the charger was being detected correctly. My 1A Samsung non-Nexus 10 charger seems to supply ~900ma to the battery which is as much as you should expect out of a 1A charger. My Nexus 10 charger supplies ~1600ma to the battery. This number seems slightly low but at least indicates the charger is detected correctly.
*If* the pogo charger does indeed charge faster, it will likely be because the pogo charger is able to supply some current that is asymptotically closer to 2A. In other words, it will not charger much faster than the USB charger.
On the other hand, the pogo charger will still be nice to have as it will allow simultaneous usage of USB OTG and charging.
Like I said before, I was unable to dig very deep because I'm out of town and browsing sysfs and kernel source on a tablet isn't the best experience. So, the info I found might not be 100% correct.

There are many indicators throughout the kernel but for brevity I'll post what I think is the most concise.
https://github.com/CyanogenMod/andr...ng/arch/arm/mach-exynos/board-manta-battery.c
Line 773-776
Sets the current to 500ma if USB is detected on the pogo or 2A if AC is detected.

Well if you're reading 1600ma using the standard ac adapter that comes with the N10 and possibly closer to 2000ma (say 1900ma) using the pogo, then that is 1/5 faster charging. In terms of time that is quite a saving.
Of course, that is all speculation

USB current limits
I thought I'd post this as information I found while doing a spot of light reading
The current specification of a USB 2.0 port can be a maximum of 1.8A. Within Constraints.
"Battery Charging Specification 1.1: Released in March 2007.
A usb charging port places a termination resistance between D+ and D- to allow the maximum 1.8A", meaning that at this current, there can be no data transmission.
This appears to be increased for USB 3.0 standard.
"Battery Charging Specification 1.2: Released in December 2010.
Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A."
citations come from documents here:
http://www.usb.org/developers/devclass_docs
As POGO pins do not have to follow any specification the only limit is the current the board & charging circuit can handle.

Look at the specs on the wall plug in unit. It's not a charger it's a 5V power supply and the charger is inside the N10. However the charger is setup determines the charging rate. Like mentioned above, it may not matter if you "could" use a 10A at 5V power supply.

Fast charge & USB

Hi everyone, I'm looking for more info about the fast charge function of the Note 4: I can read on the charger that it either provides 5 on 9V. Does this mean that I can supply 9V on the USB port to fast charge my note 4 ? Does anyone know how the charger detects wheher it it should supply 5 or 9V?

Yes, it means that that charger will deliver power at 9 V (at 1.67 A) to the phone.
As for how it decides which voltage/current to use, it'll be as a function of the battery's charge level, temperature, and probably some other factors, but that's getting into some very specific settings for the phone/charger system by that point.

I agree that it might be damaging to the battery (but obviously not extremely damaging). Why else would there be the option to switch off fast charging? I've switched mine off anyway because I have no use for it as my phone charges overnight and makes no difference how quickly it gets to 100%.

I personally thought the option to disable Fast Charging was Samsungs' way of reminding us, or letting the uninformed know, that it can do it.

The generally accepted rule amongst radio control hobbyists is that provided the battery is well made, it's not the current that'll kill a battery - it's overcharging it (over 4.2V per cell on a LiPo). Provided that the charging circuit is good (and I have no doubt it is of a high quality) we shouldn't see any degradation in battery life when used with the fast charge process.
Others may chime in with more info, but that's how I understand it.

l believe the fast charge is safe for the battery as it charges it at 1C (=1hr charge) which is actually not so fast.
Here is my tip: I have an old charger to charge overnight and use the mote 4 charger only for fast charging during the day (I leave it in my bag). I'm actually lookingfor a way to make a fast charging battery bank.
So here is my question again: has anyone tried supplying 9V to the phone ?

best device in charging
its charging up the whole battery in about an hour, i really like that and the battery gives me a full day

So far right now i can talk for about an hour and play games for about an hour and leave it on overnight and all day and still have 82% left. I'm super impressed!

YOAH!!! Thats insane!

I know that the amperage on the charger is huge in its speed.
I used many custom Roms and kernels in the past on other phones with fast charge. I used several chargers and always charged much quicker with higher amperage outputs. Some were as low as 300 MA to as high as 1.2A. This is why the amperage is so high on this phones charger. The voltage is needed to push the charge quicker. Good luck finding high A charger at 9v.
My 1.2A charger i use as backup is much faster then the 500/700ma ones I have but they are all 5v and can't compete with fast charge.
Sent from my *ROOTED* Note 4 SM-N910W8

I'm also looking for a power bank that would be able to charge at
- 5V 2A,
- 5.5V (Galaxy Tab S)
- 9V (Note 4).
- with 2x18650
- able to charge itself fast too;
- charge-through (charging a device while changing itself).
i now have this ENB model, but it does not deliver 2A to Tab S (and charges at 5V not 5.5).
And it charges itself with 1A even from 2A-capable power supply.

Hi all,
I notice something that the note 4 does not charge fast after I installed S-View cover (original one), although an indication appeared that it is using the fast charging function.
I guessed it assume that the cover is open and charge slower. However, if I removed the S-View it charge noticeably faster.
Do you think this a bug in firmware ??
Thank you,

The so-called USB fast chargers query the device to be charged. Devices capable of fast charging at 9V DC have additional circuitry in their USB ports that the charger can detect. If the charger doesn't detect the circuitry, it falls back to 5V DC mode, like any other USB charger. Assuming the fast charger is functioning correctly, it should not over-charge an older phone or tablet that doesn't support fast charging; it will simply take as long as the original "dumb" USB charger did.

Nexus 6 quick charging

Hey guys I just bought the Nexus 6 and been looking around here and didnt find anything on best ways of charging the phone. I know the phone comes with the quick charger, but I tried it and the phone got real hot and I am pretty sure its not good for the battery in the long run.
That being said I do not want my battery to start losing charges since it does not have a replaceable battery. I am just curious if anyone on here uses other methods of charging the phone or better yet if anything is proven to be safer to charge. Right now I am charging the phone with my previous Samsung s4 charger and seems to charge fine, but if its not good to do this I would like to know sooner than later.

The n6 is meant to charge fast and isn't the first phone to use fast charge technology so I think we are fine using the stock charger.There's no way a battery charging that fast isn't going to get hot.

Define "real hot."
It is normal for the phone to get quite warm when charging. It should never be hot to the touch though. In this context, by hot, I mean you're unable to hold the phone. If you're able to touch the back, and keep your fingers there for more than a few seconds, then the phone is warm, not hot. Anyone who has had a battery overheat can tell you that the difference is unmistakable.
Chargers will, by definition, heat the battery to some extent -- how much, depends on what kind of charger. The order (from warmest to coolest) is: QuickCharge 2.0 (Turbo Charger), qi wireless charging, QuickCharge 1.0 ("Traditional" 2A charger), Regular 1A charger, USB charger (500ma). However, the heat produced by ANY of these chargers is normal, and the battery was designed to handle it. The life may be lessened by the heat to a very small extent, but it should still last way longer than the 1 to 2 years you'll likely own your phone. Plus, technically, the battery IS replaceable. It's just not designed to be user-replaceable, but there are businesses that will replace them. Or... you can purchase an after-market warranty, most of which cover batteries.

It is normal for the phone to get quite warm when charging. It should never be hot to the touch though. In this context, by hot, I mean you're unable to hold the phone. If you're able to touch the back, and keep your fingers there for more than a few seconds, then the phone is warm, not hot.

I meant just warmer than normal use of the phone. I understand the phone gets hotter the faster you are charging, however I charge my phone every night so what is the point of the quick charging except when I am at work and my phones about to die?
I just feel that the phone will last longer by not quick charging it, but I could be wrong. What I really want to know is if anyone knows if its better for the phone if you just charge with the 1.0 and if so which charger should I use? Maybe another motorola one or would the samsung one work fine?

Technically, yes, it'd be better for your battery, but realistically, you'll never notice, since you'll probably get a new phone long before battery life becomes an issue.
However, to answer your question, any 1A charger designed for Android devices will work (If they're not designed for Android, they'll show "Charging (USB)" in the battery monitor, and will only charge at 500mA). The brand isn't really important, as long as it's a reputable brand. (...and before you ask, yes a 2A charger will work fine too, but will heat your battery more than a 1A charger.)

Ok thanks...I guess ill continue to use my samsung 1a charger since it works. And I know that I wont have this phone for the whole 2 years, but if I charge the phone every night anyway why take the risk of damaging the battery at all with a stronger charger when I dont need it right?
Anyway thanks for the advice and ill keep using my samsung charger.
Thanks

I put my phone on a wireless charger all night and it gets a little warm but nothing to lose sleep over.

[Q] Quick Charge 2.0 confusion

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

I'm using the franco kernel at the moment and as far as I can tell it doesn't have any options related to charge speeds. I'll look into other kernels.
Thanks for the info!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.
There isn't a need to switch to other kernels.

@zephiK You misunderstood my question. The problem I'm looking to solve is the slow charge rate from the chargers in the original post.
To add to that. My macbook also charged my old galaxy phone @ 2amps but with my n6 only does 500mA.
Nothing wrong with the turbo charger

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.

@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand

Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.

Thanks! I guess I'll have to replace the chargers/battery

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.

I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify. The person I quoted below explained it a little better than I did.

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people
