Usb fast charging

I can't understand why it is so slow to charge!
I tried also nuePower... but with no results.
The phone charge slow (in the same usb port where other htc phones charge quickly!)...
Do you have suggestions?

usb charging is just like that.. if you want it to charge faster, use the wall charger. although, from what i've heard, slow charging is better for the battery anyways.

yes but I usually use my tp as modem and happens that phone discharge quickly than what it charges!!! so after 3 hours phone is completely discharged!!!
This happens only with tp and not with touchHD neither with TytnII!
Incredible!

Although the voltage is the same on a PC USB port as on the wall charger, the amperage is much lower. Thus, the phone will charge significantly faster on the wall charger.
However...
I also use my TP as a modem, and I can leave it on the web indefinitely. If yours is running down, perhaps there's a different issue at play - if you don't have any power hungry apps running in the background you might just have a borked battery or USB port...

Just put your phone off... the charching goes much faster...

I tried just after hard reset without installing any application before.
I'm using Energy ROM and I'm quite sure ROM doesn't have any problem...

I do have the same problem with my Touch Diamond. When connected to my PC or even using my car charger, it will discharge completely after 2 or three hours of using, say, GPS and a few 3G connections to check traffic.
I can't use my Diamond as a modem for the same reason... I have flashed several roms and radios, nothing changed.

Check if the TP really charges! The unit switches off the charging mode when it gets too hot or better too warm. So e.g. when in use as a GPS in car typically mounted on the windshield, it gets too warm pretty easily as GPS is quite an energy hungry application and quick discharging also heats up the battery.

P.S. If you are using the TP in car and have aircon, then try to direct one of the cold air streams to the TP to keep it cool. That helps to prevent the switching off of charging mode.

Try tbattery
I use the Energy Rom and it has a utility called tbattery that can show you whether the phone is charging or not and at what rate. Would at least tell you what's happening in the phone. Also gives you the internal temperature of the phone. I've found anything higher than 41 degrees c causes the phone to go into a slower charge mode; it's possible that a higher temp could stop charging altogether - however it should still allow you to power the phone and not use the battery....

I can use phone as modem and still charge it via usb. maybe try a different rom?

I can do that, too ! The problem is the phone charges too slowly, so that the actual power consumption is higher than the charging...

I think that it depends on how you use your phone as an Internet source. I use wmwifirouter, and last time I plugged into ac, my batery still ran down. If your phone lasts 4 hours as a wifi router with no power and charging takes 5 hours, you are operating at a defecit.

I'm using 3G and Internet Connection Sharing through USB cable.
And my diamond charges completely in less than two hours using the wall charger.

Normal behavior, USB port doesn't have enough "juice" to charge it faster.
If you want a quick charge - use wall charger.

1) I can't use tethering through USB if I use the wall charger
2) I use tethering when i'm NOT near a wall power outlet, obviously
3) I don't want a "quick charge"... I just want the phone not to loose charge.
4) I have owned many WinMo devices and this is the first one that will not hold charge while connected to USB

Start -> Settings-> System tab -> Power
There will be a check box that says "When device is turned on, do not charge the battery when connected to the PC." Make sure it isn't checked.
That's the only thing I can think of right now. If I think of anything else, I'll post it.

Thanks for the hint, but it isn't checked.
I think it's just that the phone requires too much power
And it's getting very hot very fast, which will hinder proper charging, too.
I wonder if other modern HTC devices have the same overheating problem...

hello
sorry for pushing up the topic with no sloution but new question, but yesterday i get mad when after two hours of playing streamed music + being connected to wifi my TP battery died :/ Phone was connected to wall charger (oryginal from HTC) and still i was not enough. Damn it didnt happent ever to my blueangel/eten/hermes or any other earlyer device i had. Really im starting to be angry on my latest choice of this phone i should have stay with kaiser
sorry for spelling mistakes but my English is more verbal than writable

My s3 is losing battery while plugged in.

Ive been using my s3 for about 40 minutes on CM10. Plugged into a dual usb charger connected to not ip port, which in the past i have used fine. I have lost 5% battery in this time. Current widget doesn't work yet with S3. Suggestions?
Edit - The first time I got the phone after a full charge and discharge, while plugged into stock charger and before anything root, the same problem happened.

From what I heard, the charger can't charge the phone fast enough when you are using it thus the losing charge while plugging in. If you are talking about losing percentage right after you disconnect the phone from the charger, that is a feature, I do not know at the top of my head why it does it.

If charging through USB port (and many car chargers) you're capped at 500mA vs 700+ for wall chargers. You can install a kernel that supports fast charging and you will get 700mA through USB.

I'm having the same issue whether charging from usb or a power outlet. Charges for a bit initially, then drains. Happens with different cords, too. I'll pick it up and it will feel warm, see that the battery is lower than when I plugged it in, then put it down. Then it cools off and starts charging again. Any ideas?

Same here except
i have the same issue, i had stock Touchwiz and suddenly the phone started to discharge while on charging outlet, tried different chargers, outlets, different ports, etc. still wouldnt work, i even deleted several applications and turned off several phone functions, etc. still nothing, then i rooted to CM10.1 and the same issue still presists, the phone charges a bit then discharges weather i use it or not. the only solution to charge it, it seems to be by turning off the phone. i think it has to do with the usb port on the phone as i even had the battery changed and it still would discharge while on a charger.

S3 Battery Decreasing while charging SOLVED !!
Hey i have 100% Solution of this with this you will your battery life !
i got same problem too but i solved now i'm happy
this is so easy , for all samsung phones and android phones !
Just install battery doctor (cheetah Software) from play store
optimize your phone and then charge
your phone will charge fastly !!!!!!!!!!!!!!!!!!!!!!!!!!
with this your battery life will also increased !!

Have someone had problems with the fast charging option?

hi, since i got the phone (2 month) i was very surprised because the fast charge, 1 game of lol was enough to get 60% or more, but since last 4 or 5 days, i have noticed that it does not longer charge like before, it used to need around 1 and a 20 min to charge all the battery, but now it takes around 2 hours, like using a normal charger. Thanks, and btw english is not my first language :silly:

Happened to me once, rebooted the phone and fast charging was working again.

fastcharge works only with screen off and no app opened (es. game/video/music/etc)

Also make sure you using good quality cable. Some weak ones can "block" quick charge. Best setup is just the stock one.

It still fast charges while in use... just won't be as fast since you're drawing power too. However, using the battery while charging at the same time makes the battery heat up very easily (true for most all devices even on normal 5V/1A chargers) so it is always recommended to keep your device in a state of minimal drain while charging.
I've had issues on past phones where sync/charge cables (stock ones even) get detected as USB connection instead of AC and charge at limited amps because of it. Swapping out to a new stock cable or even a dedicated charge cable with no sync pins usually solves the issue. EDIT: as przemo3679 says below, Qualcomm Quick Charge standard negotiates the higher voltage mode over the data pins, so "charge only" style cords with the data pins missing or shorted will not work in QC mode.

no, the snapdragon 810 has overheating problems so if the screen is on the fastcharge is disabled, is the same reason because while you play and the phone heat up the display brightness cant be over 75%.

It does not disable the fast charge simply because the screen is on. That is how you keep phrasing it.
It disables fast charge if the phone is overheating. Technically this is not the same thing.
Many common usage factors (gaming, heavy mobile data use, high screen brightness, etc.) can make the heat build up fast enough to trigger thermal throttling and disable fast charge of course. But it is also possible to tweak the kernel and thermal files and adjust usage (light browsing only, use strong wifi in lieu of mobile radio, reduce screen brightness) to keep the phone in fast charge even when screen is on.

I disagree. If phone is charging, but not fast it is usually caused by damaged data lanes, or too big resistance on some lane. Cables without sync lanes would work on some devices, but would not on others, current will be limited to 500mA. It's hard to say on which.
And w/o data pins quick charge can't work on any device. Phone use it to communicate with charger to set best voltage and current to actual device.
As i said, original is the best. U can't blame damaged cord for charging issues.

I have a usb voltmeter and I can assure you that it use the 9V charging while the screen is on and also when it's in use (so the screen is on and the phone is in use). The amp only drop when percentage is near complete charging but stay at 9V so technically it still use fast charging.
Quality of the usb cable is very important but quick charge (or fast charge as LG call it) use of higher voltage make the quality less important. I can use a 3 meter usb cable for example, with a iPad charger (5V 2.1A and genuine) I can't even charge my flex 2 (it can't draw more than 300mA and the battery deplete more slowly but don't charge even is not in use). I won't explain why a higher voltage is less sensitive to resistance (the resistance rise with the lenght of the wire) but that's the reason we use high voltage line to transport electricity.

OP here. I use the stock charger and cable that came with the phone, plus they dont see damaged or very used. Still feeling it "slow" :s

I have H950 Stock 5.0.1 , sometimes quick charge doesn't work properly so I turn the power off and charge while off for half an hour it charges very fast and reaches over 70% then turn it back on

I agree with You, in short words more current (A) means more temperature. At the same power (W) bigger voltage (V) means lower current (A). But i think u didn't get what i mean. There is some kind mechanism, which block quick charge when cable is too crapy. I had one of those, and it was fully functional witch data lanes, but it was designed to power 0,5A device. When i tried to connect it to the Flex it said slow charging (or something like that). I think it somehow measures resistance.
I also want to refer to your words: "quick charge (or fast charge as LG call it) use of higher voltage make the quality less important". It is advantage of the quick charge, but not main purpose. U can always made a bit thicker lanes. But you can't change connector. Remember that USB 2.0 standard was designed in april 2000, so it is a bit old now . Back in the days nobody was thinking about 5,5" monsters with 3Ah batteries. Flex is charging with around 15W and it is too much(it can dangerously hot, create arcs etc.). Remember that conductor heats up the most in the greatest resistance point, which is connector. Now we have USB type C, with better connector, which can hold on greater currents, but if we have standard, why did not use it (QC2.0 & QC3.0), and have thinner cord?
About charging time, mine from 0-10% to about 90% takes about an hour.

Guys i solved the problem, after noticing that now the animations (rotation, multitasking, and others) werent working, i decided to do a hard reset, now everything is working, fastcharge, animations, etc. not sure what was the cause, a friend told me was a virus for watching porn lol

I see exactly what message you get, it's the same message when you connect to a computer, right?
It detect a computer and limit itself to 5V and 500mA which was the standard back in the time.
I know someone that fried a laptop motherboard with a vaping bypass, so that limit have purpose.
What is strange is if you get that message with a faulty cable and a lg fast charge charger because the charger should only send signal to negociate quick charge.
I don't think it can measure the resistance or the intensity, or at least the measurement is not monitored in some app because when I use a cable with high resistance and the battery percentage don't go up, I don't have that message.

My bad with translation. If you have no data lanes phone will usually charge with 0.5A as You said, but when i used this crappy one it was something closer to "To maintain best performance use original standardized charger". It was charging faster than 0.5A, but it wasn't QC.

I think you mean the opposite, without the data pin (2 center pin on usb plug) the phone will think he is on a charger and don't limit itself for drawing current even if it's connected to a computer.
Normally a usb device have to be limited to 5V and 500mA,
But qc need the data pin to negotiate the qc voltage so if you use a usb cable without data pin it will stay at 5V.
I have one cable that top at 5V and 100mA (around 80mA normaly) it's very low and it can't charge the phone, it just make it lose battery more slowly, in that case I don't have the message you talk about. That message should appear when it's connected on a computer. My usb voltmeter also have a feature to block data pin, when that feature is activated the message don't pop and it draw more than 500mA from a computer.
There is a good voltmeter on aliexpress, I can make you the link but it's easily recognizable with a transparent blue case, around 10$. There is many model so be sure to take the quick charge compatible. You can make theory on many things but you can truly understand only if you try by yourself.

Charging very very slowly

Hello,
I have had this tabled for a while and it was always charging extremely slowly but I never took it out of the house so it wasn't a bid deal for me. However I have given it to my mother and she uses it in other ways. Anyways, the note 10.1 is the slowest charging device I have ever seen. It takes probably 48h-72h to charge it completely. I am using the original cable and power brick, I have tried ALL the outlets in my house, I have tried using the computer, I have tried using another cable (probably like 5 different ones) and other bricks (from iPads, my note 5, etc) and nothing is working. I have seen other posts regarding slow charging but none of them solve my problem.
Thank you

Thats is not normal .
I would factory reset and flash a stock rom .
Swap battery or take to a service centre .

"probably"?
You can't troubleshoot perceptions and guesses. How long does it actually take--repeatably--to charge from what percentage to what percentage? (i.e. "Went to bed, battery was at 40%, charged overnight for 7 hours and battery was at 60%.")
There are apps to check charging current (Ampere being one of them).
The fastest charge you can get is with the OEM charger in an outlet, not a PC.
Understand that this is a 7,000mAh battery without any quick charging applied to it.
Additionally, if you are using the device whilst charging it, you aren't really charging it since the drain is about the same as the charge; you'll effectively neither charge nor discharge.
Finally, check for battery-draining apps; you might not have a charging problem but an app-drain problem.

The time varies, but it is between 2 and 3 days to charge from 0, never less.
I do use the OEM charger and cable and an outlet.
I do understand that but 2 days seems a bit of a stretch, don't you think?
I am definitely not using it while charging, because it's impossible. It just doesn't charge fast enough to be able to use it. It drains quicker than it charges.
I highly doubt that, I only have YouTube and Chrome installed on it.

Above 6 hours with stock rom and charger is abnormal .
Usual replies .
One cable
Two charger
Three battery or connections .
Four USB port
Five motherboard .

Yeah, 2 days isn't right. It also shouldn't be discharging faster than charging, especially with the OEM charger.
I leave mine plugged into my PC (only 500mA max current) with the screen on (about medium brightness, mostly black screen, which is most power-friendly for OLED) using LectureNotes all day and it will neither charge nor discharge (technically, it's charging at the same rate it is discharging); the percentage doesn't move.
What does Ampere report?
Do you have another charger you could try? any 5V and at least 2A would work.
Also, ensure your cable isn't intermittently open (a break in the cable, temporarily disconnecting the charger).
If the cable and charger are good, then the battery would be the next likely culprit, followed by the charging circuit.
Finally, ensure heat isn't an issue (is it in a case? remove it).

Mine was messed up but I concluded it was the port and cable. I got a new cable and then replaced the charging port and viola. Charge time went from 8 hours back to the usual 3-4

Bug? Disconnecting charger at 100% and replugging it?

Hello, can anyone else reproduce this bug?
When my phone is charging and it goes to 100% it will still have current flowing thru it(AccuBattery) even tho the charging LED is off and if I ,in that moment, disconnect the phone from the charger and then reconnect it to the charger, the current goes to 0A? The battery voltage at that time is about 4.45V, is it overcharging?

No, it's not. As an Electrical engineer, i can tell you with certainty that there is nothing wrong with the behavior described. The feature wherein a mobile device stops charging and uses only current provided by the charger is called Power Passthrough, Which only a handful of devices can do right now. Example for that is the Asus rog 3.
Regarding the voltage situation, accubattery only refreshes the charging state (status inApp) after you disconnect it due to system limitations. A clue for this limitation you can find in accubattery itself; when you want to measure the battery capacity and it says disconnect the charger first. So no worries you phone is fine :good:

Yeah but that's the thing, when the charging led turned off it was still drawing about 1A of current until i reconnected it and it just didn't draw anything, shouldn't it restart drawing if it drew it before disconnection? I mean it's just kinda weird that it started powering the phone directly, instead of charging the battery, only after reconnecting the cable...
