[Q] Fast Charge - AT&T Samsung Galaxy S II SGH-I777

Good afternoon/evening/morning/whatever,
I was just wondering if anyone has used "fast charge" mode? Or uses it regularly? From my understanding it will charge the battery at rates upto 650 mah while hooked up to USB. (Normally phone only charges at that rate when on wall plug I believe) I know on a normal USB 2.0 port this will result in over-drawing the port and that's bad. However from what I know USB 3.0 support current capabilities upto 900 mah, so it shouldn't be a problem then.
I'm just curious because i had read the other day that someone said it would do damage to the phone, so is there something I'm missing? From my understanding the only damage that would be done, would be to the computer that's being overdrawn. So long as I'm hooked up to a USB 3.0 port shouldn't it be fine?
Thanks!

I did that numerous times with no problem. It should not damage the phone under any case, though it can damage your USB port by overloading it with higher than designed current. Also though as far as I know USB ports on modern motherboards has protection against overloading.

Yeah it can destroy USB ports, but definitely shouldn't harm your phone. I have my USB current that high because my phone thinks it's connected to a USB, when its actually on an A/C charger. Therefore making my phone charge slow....

I had mine on fast charge overnight and forgot to switch it back to normal. Later in the day I plugged my phone in my car and left it for about an hour. When I went to take the phone off the charger it was like holding a lava rock. I'm talking HOT. I turned the phone off and took the battery out for about 15 min and it cooled off. The point of my long boring story is that even for as hot as it got, I don't think it caused any damage to the phone

[Q] Not charging? :S

Hmmm, this is a weird one guys.
I can charge my X10 only if it is plugged in to the USB port via the computer. However, when it is plugged directly into the power socket, it does not charge. Now, I've tried two different chargers, and both work when charging another device (my iPod Touch).
I don't understand. The cord can't be broken, since it works when charging from my computer? Yet, the charger (the thing that plugs into the wall) can't be broken either, since another charger didn't work and also both have the ability to charge my iPod.
What's up? :S
Thanks in advance.
NOTE: Even when charging while off works on the computer, just not when it's plugged in (and I am not using a custom kernel either). I doubt the ROM matters (since it still has the above problem while charging when off), but even so, I'm using v061 of Wolfbreak's 6.1.3 ROM.
Bump bump, bump it up!
Do you use the original SE in-wall charger? If not, thats the problem, if yes I recomend to test with a different wall charger (eg. from another device)
May be the cable it faulty? Because the PC charging uses a less amount of Volts (to my knowledge) and the charging while connected to PC is very slow. Did you try with any other Official cable?
It could possibly be your cable as mine broke a few weeks back (Same Problem), I just replaced the cable now its fine
Guys :-/
Went out and bought a new cable, and still not charging from the power Only from the slower laptop USB port :'(
I think it may be the X10 itself..
I am still suffering from this problem And sometimes when it's connected to the PC and displays 'charging', it instead discharges

Maybe the connector in the phone is broken????
Yep your usb port is broken, mine did exactly the same thing. You will have to send it to fonebiz in rockdale, nsw. I just got my phone back, took 6 weeks to repair!

Rockdale? 6 weeks?! Not going that far. :-/ I can live with just charging from the PC at the moment.
Thanks though Sad news indeed
Is is still under warranty? It will eventually stop charging from the PC too. I was waiting for parts to arrive so maybe they have them in stock now. That was 6 weeks from melbourne and back.
Going through the same thing in the US. I was told repair would be 5-7 days, but I'm sure I'm looking longer. If it comes back within the time frame they gave me I will be pleasantly surprised. I hope you're still under warranty and do your self the favor and send it in or soon you will have a very expensive paper weight. Good Luck!
I went through the exaxt same thing. It stopped charging from the wall but could only charge from computer but eventually stopped charging altogether.
Did you try taking out the battery and plugging in with the original se microusb cabe to the wall. After 5 min. put the battery in. First time didnt work for me but then i took out the battery again and put it back in immediately and then it turned on.
try getting a usb-to-wall charger, and plugging your computer usb cable into wall.

Out of curiosity, how long before each of your X10's stopped charging altogether? :S
Because, for me, it's been longer than two months and throughout that time I've managed to keep charging it via the computer.
Thanks.

I've 3 usb-to- chargers here:
From a MP20 phone, generic charger that can't charge my phone and also can't charge most of other devices, output power and voltage are low.
From an old Ipaq(not ipad) it does charge my x10 for some reason takes longer than the original, it says on it 1000mA and 5V, I don't remember the real amp and voltage on it.
And the original one, always charge really fast(2 hours for a full 0 to 100% when the phone is ON)
Conclusion, buy and original charger if you not using one, which seems to be the case.
OR, update your baseband if possible, as battery issues are normally related to baseband are normally the cause of this errors.
To make sure you can always try to do a SEUS repair.

Sorry to say this, but your are wrong man.
My charger says 5.0V which is exact the same voltage as any USB ports(exception for some internal USB ports used commonly for bluetooth and other low consumption devices that use 3.0 to 3.3V).
The difference is mainly on the amount of power amp it can supply, the original usb cable + wall charger provides 700mA, while in the PC USB 2.0 ports provide 500mA, 1.0 USB provide 100mA and 1.1 I don't remember now, generic usb wall chargers say sometimes they provide 500mA but they mostly provide 30l0mA and sometimes they do not provide on 5.0V they oscillate between 4.6 to 5.2V a good usb port have to provide 4.95V to 5.1V any difference from this may even burn a phone if higher and not charge or reduce a battery life if too lower.
Everytime a battery is not charged up the end of 100% they battery life gets a bit reduce as next time even if you leave it to charge up to 100% it won't really be at 100%, this can only be seen by measuring the battery voltage after the charge, fully charge it must reach up to 4.7V
on the battery or something like this.

If the cable is too thin(like 1.0 usb cables they can't handle 500mA if connected to an already extended usb port it may not get recognized and also not even charge.
Laptops usb ports may not allow 500mA it different for every laptop, some work, some doesn't and others your have to set that on bios.

Always when connected to the PC it should say charging, if it did say discharging at some point then there was something wrong.
But charging on the pc is very slow and not good.

[Q] Please Help w/ charging..

here's a weird one..
when using the wall charger that came w/ my phone, instead of charging the battery its actually draining it, the battery icon says its charging/plugged w/ power but after leaving it plugged in eventually it died out, but if i plug it in my pc it charges w/ no problem..
pls help me or enlighten me as to whats happening...
thanks in advance.
Strange. It should be the other way around. USB 2.0 sockets push 500mah which isnt enough to charge the S while the wall chargers provided are 800/850. Perhaps a dud socket? Try another and if not your charger is fĂșcked.
yeah, i think its my effin charger, i plugged it in a diff outlet still same, i tried using it to charge my iphone its not working as well. thanks for the help.

For me it discharges faster than it charges. It may charge off yours but typically it'll be very slow or not at all. Some ports push more AFAIK, but the standard is 500max.
I also noticed that, if I have WiFi on, the phone actually discharges when connected to the PC (when used anyway).
I don't know how much current is provided though, never measured it.
If charging through USB is fine then it might be that the charger is shorting the battery + and - through some resistance.
Try another charger and see if it helps , and replace the faulty one. You don't want to break your battery.
On my laptop usb port it will charge just fine. Slower than the normal charger but it does work.
On my desktop pc otoh it drains more than it charges. So there probably is a difference in output on the usb ports.

If you were using "front ports" these are often underpowered compared to ones mounted on the mobo(back of case, or all laptop ones).
I connect my phone via my front ports and it charged just fine actually...
I am behind the computer quite a bit and my phone keeps its battery and charges when attached, even when I'm installing a bunch of apps (I tend to browse the market via my browser and pick up apps as i go) I still don't discharge...
It could be a voltage issue with your ports, but with my frontal ports I notice no problems...but anyways, this isn't about the ports, this is about the OP's charger.
To me, it seems like your charger is faulty.
Hi,
I wrote about a similar issue I was having with the phone discharging when connected to USB.
http://forum.xda-developers.com/showthread.php?t=1573336
From what I could tell in my tests that I did the issue is when the phone is connected to the PC and THEN the PC goes into Standby mode. Even on a powered USB hub the phone charging mechanism does not reset correctly and continue charging but begins discharging.
I would have loved if someone else could have tried to reproduce what I wrote in that thread but no one responded. For me the only solution is to charge directly with the AC power and not through the USB as my PC goes in and out of standby regularly.
Phone charghed with USB will drain batery faster then phone charged with wall charghed.
It was thread in xperia arc about that, the test bring that conlcution.
So i recomend to charge with wall for better batery efecienty.
Sry for language im little sleepy. :$

Using non-verizon branded chargers

I have a ton of micro-USB chargers that I've used with my GNex and Evo3D with no issue. The only consideration I take into account is Amperage, and I toss the ones below 800 mAh. Last night I plugged into one thats around 850 mAh and left my phone to charge all night (at around 5%). When I woke up, the phone had completely discharged without any sort of recharge.
Since this isn't a Nexus phone, am I locked in to only using verizon branded chargers? Is there a way to defeat that with root?
I haven't had any issues with that as I use all different types. Maybe just try another or maybe it wasn't plugged in all the way.
What voltage is it rated at? It could be that or that the charger is bad somehow. I charge mine nightly with a .7A charger and it's always been full when I wake up (about 30-50% when I go to sleep).
I have the sprint note 2 but they are essentially the same phone so here is what Igot for you:
there is no "smart" element to any chargers in the market, so your phone shouldn't know the difference between Verizon brand and the devil's own brand
if you look at the stock charger it outputs 2 amps...the phone needs this and in my experience it needs at least 1 amp in order to charge instead of discharging slower
also there is a known issue with all note 2s that the cable will not sit snugly inside the port causing it to be a bad connection... just make sure you put it in hard (no pun intended) and it shouldn't be a problem

Yeah, if you take a close look at the micro-usb port, it is recessed a bit. Make sure you plug the cable in firmly.

I think this was likely the issue. The charger is rated at 1 Amp, and I tried it out again last night and it appeared to work for the few seconds I had it plugged in, so I must not have had it in there snugly.
So I just tested with the same charger, and when I plug it in, it beeps every half second and flashes between the charging/discharging symbol, and does not charge...

I don't remember where, but I remember reading about someone with this issue where they were using their phone as a gps while charging it and it died. Someone commented saying that the culprit was probably a faulty charger. Sounds like they were right.

I have seen this same thing with two Droid X's plugged into the same 2A charger. One phone would charge and the other would do exactly as you describe. It didn't do it all the time, it just depended on how low the battery levels were on each device. How much battery life do you have left when it does this? You may just need to use a higher amperage charger.
I have not received my Note II yet, but it sucks that I will most likely not be able to charge it while tethered (USB) to my laptop.
Based on the info I could find (kernel driver), the phone will accept up to 650mA of power, so anything over that should charge the phone at the same rate. Voltage shouldn't be an issue as it is charging via USB, which is 5V (+/- 5%). Unless someone has an amp probe to put on it, we can't tell if it is actually pulling more or less than what the driver specifies. And, as someone else stated, the phone can't tell if you're using a genuine Samsung cable and charger, or a $1.00 made in China cable/charger, as long as they both output the same voltage/amperage, the phone will never know the difference.
Based on what you said though, if the phone is constantly seeing the charger connect/disconnect, that would drain the battery even faster.

DNA discharging when charger is plugged in

Whenever i plug my dna into my computer to charge via usb and turn my screen display on to use, the battery either doesnt charge or goes down in %. I find it kind of weird that the phone is using enough power with just the display on to counter the charging. Is anyone else seeing this occur or is my device defective?
Not entirely sure. I know when the phone is fully charged it stops charging so you don't "overcharge" your battery, it just runs off the AC.
Did you try another USB port on your computer?
probably not getting enough power from the USB port
I'd return it.
Sounds defective to me.
Sent from my ADR6400L using xda premium
Chances are its just your usb port. A lot of usb hubs can't put out the correct voltage/amperage to support the processor and screen from using the battery quicker than it can charge. Don't return it. Try it on the supplied charger. If it continues to do that even on the OEM charger then yes return it.

Seems ever since I updated to the latest OTA update, if I plug my phone in on certain chargers I get a notification stating slow charging enabled please connect to your factory charger. Anyone else having this issue?

Same here. Glad to hear it is not just me. I just got off with NA HTC Tech Support. There official stance is that they do not recommend or support using any device other than the official charging cable and plug in device. They went as far to say that they do not support charging in the car. I just about flipped my lid on the phone.
Here is the link to their site: http://www.htc.com/us/support/howto...783&p_name=droid-dna-by-htc-(verizon-wireless)
"Only the power adapter and USB cable provided in the box must be used to charge the battery"
I was told by Verizon that this was just a scare tactic, while HTC says I am not getting the right charge and they have no answer since they do not support DC charging in the car. Any info people have is appreciated. It works fine with Hard Wired DC -MicroUSB, but not with any USB Plug in.
Any apps that would help me measure the amount of charge it is getting?
Thanks in advance.
What are the specs on your car charger?

So odd that they would do that, especially with the power draw of the phone. However you can charge using the battery packs?
My car adapter is a Macally USB car adapter model carusb10 output 5v/2.1 amp x1 500mA x2.
As for my house adapters the RCA 2 port USB wall adapter. 2.1 Amp x 1 or 1000mA x 2 I believe.

Everyone with a stock DNA unplug your charger and flip it around. As in flip the prongs. It should give you this message even with the HTC supplied one. Or try this. When you use another charger and it gives you that message unplug it and flip it. It should straighten out. I dunno. Something about the way the power is drawn.

I have tried several different USB adaptors, from Razorfish(BestBuy), Belkin single USB input 2.1amp, innocell (RadioShack) dual SUB 3.1amp. Same problem on all.
On the other hand, any direct Wall connection with USB cable attached seems to work fine.
Also, I have the Motorola p4000 battery backup and when I plug that in, it also works fine and views it as AC.
Swapping the pins didn't work for me, same issue. Its a pita for me especially charging in the car because when using phone for navigation it charges so slow that it can't actually charge my phone and my battery decreases. I've went the route in the car I use my nexus 7 charger connected to an inverter.

From my phone conversation with Seth from HTC Support, the slow charging warning is due to the update because the update incorporates the faster charging feature that qualcomm & htc have referenced too recently (can't remember what its actually called). The phone has a new type of charging setup that makes it charge faster than some other phones.
Unfortunately some chargers (wall/car) dont supply enough voltage to activate the charging feature so while the phone does charge fine (it charges at standard phone charge rate) it cannot charge at the faster rate due to the charger.
He states that this will not harm the phone and ther phone will charge fine and it a normal time. You can disregard the warning. For those that like the faster charge rate, you have to use the right charger/cable.
Before the update our phones were mostly charging at the slower rate and that's why most didn't see a warning unless the cable being used was below the standard rate of charge.
Hope this helps

When I use the Best Buy 2.1 amp wall charger I still get the message.
I'll need to find my oem wall charger.

I haven't seen this message at all on any of my charges but I haven't charged in the car yet. My battery usually lasts for more than the while day so I just charge at night.

Well with the faster charging enabled it does charge pretty quick especially using my nexus 7 wall adapter, even with my Nokia Qi pad. But man that last percent takes a while.
As of now I'm using supercharged hatka ROM slim 3.0.3 and getting good battery life. Even in the middle of nowhere where 75% percent of the time when I'm in the plant its searching for signal. I'll leave work after 8 hours and still be at 60%
Guess you can say its the only negative I have for the phone. Trust me the battery life is much better in the plant then my old bionic. I use to have to change the standard battery after 4 or 5 hours as it was completely dead.

Last night I received my daughters replacement Rezound from the warranty company. It came with a 1 amp wall charger.
I plugged it into my DNA and did not get the notice of slower charging and it charged quicker than I've ever seen it.
Too bad my 2.1 best buy one won't.
The quick charge capable chargers must output just slightly higher voltage to trigger the rapid charge mode.
I'll experiment some day and see.
This is a known issue. It all comes down to there being no set standard for USB charging. Android, apple, tablets, they all just seem to do their own thing.
The phone is checking the pins on the charger. If the data pins are shorted, then you get fast charging. If not, then it will default to the slower USB charging.
That last update that came through added that 'Slow Charge' warning. I saw it on my gf's DNA. My DNA is rooted and ROM'd so I don't have that. You can still check for the charging speed on a device by going to the Battery page in the settings. Up on top it with either say AC (which is fast) or USB (which is slow).
The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

I kinda figured it was something with the pins if I wasn't voltage offset.
I did find that one of my car chargers from best buy runs in quick charge. The cable I fixed, rather than using a usb cable in a slot on the charger.
The best number 2.1 amp wall charger uses a data type cable.
Maybe I'll check into shorting the pins on that sucker to get quick charge mode.

The phone is checking the pins on the charger. If the data pins are shorted, then you get fast charging. If not, then it will default to the slower USB charging.
That last update that came through added that 'Slow Charge' warning. I saw it on my gf's DNA. My DNA is rooted and ROM'd so I don't have that. You can still check for the charging speed on a device by going to the Battery page in the settings. Up on top it with either say AC (which is fast) or USB (which is slow).
The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

The phone is doing more than checking pins now. I have a 2.1 Amp dual charger with pins shorted and get the warning. It happily charged in AC mode before the update. The charger can also charge a nexus 10 at 2 Amps. I'm guessing the kernel devs will have to locate the source of the warning. I thought the resistance between the data pins might be the trigger, but there is no difference between the HTC charger and my dual charger. It does seem my car charger is unaffected.
I have found that to trick the phone into AC mode you have to short the the actual cable. Hence strip the insulation off the wires and short the data wires together. Has worked for me on all my chargers.

This message does not have to do with the update. I have still not updated my DNA and have been struggling with this for about 6 or 8 months. I am on 2.08. The issue has continually gotten worse since the first time I saw it. At first it would just appear about 1 in 10 times I plugged it in to a car charger. It then got to the point where it would only not show the message with a certain car charger. Now it is showing it on the one car charger that works, but if I mess around with it and unplug and replug it a few times it will finally charge normally. The last few days it has started showing the message on the OEM charger. I have cleaned out the port on the phone and cables quite a few times now, but it doesn't help. I found that doing that only helps if it gets really full of lint and the cable rocks in the port causing it to loose connection if you move it, but it does not change the slow charging message at all. The phone is also definitely not charging at full speed when that message is shown. If I have it plugged in and it shows that message my battery actually drains if the screen is on. With the screen off I only gain about 10% per hour. I am not sure where the issue is, but I think it is different in different circumstances. In my case I think it is the phone itself, but from what I have read about others experiences it seems their problem might be the charger/cord. I hope this gets sorted out soon.

It could be the charging equipment your phone or it could also be the power source not providing enough power to the device for it to charge fast so it charges slow.
