Hey,
I noticed that the droid charge has a bigger battery but it take a lifetime to charge.. is there a better charger I can get other than the one that came stock with the phone? Please let me know. I would really appreciate it.
The stock actually charges fast compared to USB...use a higher amperage charger with the stock usb cord (so it doesn't limit to 500ma). I use my Galaxy Tab charger...works great

PC USB ports do not do a good job charging phones. they don't have a lot of power going to them. In addition, if you're using your phone while its charging from your computer you will not likely see it charging at all since all the power its getting is going to whatever it is your doing.
The same is true of car chargers. I had mine plugged in in the car for 45 minutes using the GPS. It charged 2%. The point is, the only real effective way to charge your phone is by using a regular outlet.

Correct about the pc charging; it only runs at .5 amps (500 ma) while the stock charger has 1 amp. However, the car charger really depends on what kind you're using. I use a 2A and it charges fine.

ok cool. so i could just look for a charger will higher voltage being delivered. I hope i get the right one that is compatible to the droid charge. Dont wanna burn the battery out etc
No, not voltage. Amperage. Big difference. Just get a charger with a USB port and a high amperage...I don't think you'll find a higher amp charger specifically compatible with the Charge.

ok thanks!
You need a charger that won't be seen as a USB connection on the phone. If the phone thinks that it is plugged into your computer, it will charge at roughly half the rate of the wall charger. Wall charger will charge at ~700mA I believe, and the USB/Computer connection will charge at ~400mA. You can find the actual numbers in the power regulator driver in the kernel source though.
I have a motorola 950 amp car charger I got off amazon for $5. It works well but if the screen is full bright and I'm running navagation I have seen the battery level drop. To keep up you need a 1+amp charger. That being said the harder you charge the batteries the quicker they will wear out.

This is pretty interesting. I'm not a phone dev or an electrician, but I assume these mA numbers are something that are 1) lower than what is actually safe and 2) might be able to be tweaked by a dev with nothing better to do. Not that you are even close to falling in that category, but I think many users would be quite interested in being able to get more charge out of shorter durations, albeit at the risk of burning out their phones.
Search for my responses here on charging cables... Sorry but I'm at 35,000 feet in an airliner and can't search very well to include a link. The "magic" to allow a charge current greater than 500ma is either in the stock AC charger or in a "charge only" cable. The data wires to the phone have to be shorted otherwise the phone will think that it is plugged into a computer and will start USB services and will limit the charging current. Cheapest to fabricate your own adapter!

So it wont harm my battery at all to use my galaxy tab charger on my phone? What about in the long run will it degrade faster?
I think the phone has intelligent charging logic (like the newest iphones) so if you keep it cool it will take care of itself. YMMV however!

You could have a 10 amp charger, and if it is picked up as a computer/usb connection, the phone is going to pull the same amount of current as it would just plugging it in to your computer. The same goes for car and wall chargers that get picked up as a computer/usb connection. It doesn't matter what charge rate the charger supports, the phone is going to pull the same current as it is regulated to via the kernel. The only time it won't pull the full charge current it is setup to pull is if you have a charger that is rated for a slower charge rate than what the phone wants AND it won't allow charging above its stated capacity (any good charger should do this).
I have looked around (not much though) at how to make the charge rate faster before, but couldn't see how to do anything besides make the phone charge as fast over USB as it can via the wall charger. However, from what I have read, Li Ion batteries do better if they receive a slower charge to full and will not die as fast compared to being rapidly charged.

Slow charging is true to some extent, but there is no need to charge our battery's under 1.5amp.
And shorting the two data pins on the USB doesn't work it looks for a specific resistance, I saw the ohm load somewhere, but now of course I can't find it lol..
When I get really bored tonight I will edit this and figure it out. But yeah our phones can easily pull 800ma or more with full screen brightness and maxed out processor. So that would result in no charging at all on some chargers. I use a 2a wall charger that came with my evo and it charges very very quickly. Never more than 1 hour to full charge unless I am gaming on it while it charges lol. This is using the cord that came with the phone of course so that it knows it isn't in a data enabled usb slot.

In electronics, when given a voltage source (as opposed to a current source) the Voltage is set to a fixed value. That is what our wall USB outlets are. Voltage sources
Think of Voltage like a waterfall. The water is always dropping from the same height. The voltage is always set to the same value.
The mA rating (the current) is determined by how much juice the phone can pull. Just because a charger is capable of supplying more current (say 1 or 2 amps), it doesn't mean that the Droid is going to draw that much current. However, if the droid is capable of pulling more current, it will benefit by charging faster.
Does that help at all?
*edit* Dang it. Didn't scroll down enough to see that imnuts posted already. Oh well, screw it. I'm leaving my post. lol. People who don't know about Voltage and Amperage need to hear the waterfall example at some point in their lives.

Did you read anything I posted The phone is only going to pull a set charge rate, depending on what type of connection it sees. It doesn't care what power rating the connection has, it will pull as much power as it can, up to the limit defined in the power regulator of the kernel. You can use a 1A charger, or a 2A charger, doesn't matter, the phone is still only going to pull a set. The phone will pull 475mA via USB connection (your computer) or 800mA via an AC adapter (wall charger). Unless you figure out how to hack the battery driver to allow a faster charge, those are the two rates you get, regardless of how much power the wall charger can supply.

A charger is going to provide a set voltage (5V I believe) and that is the only constant in the charging process for what is going into the phone. The amperage is going to be determined by the phone or the wall charger. The only time the wall charger will be the limiting part in charging is if its circuitry is setup to cut off charging over a certain level, and if it is rated for a lower charging rate, odds are, it probably won't cut it off and instead produce a fire hazard.
Something else people don't realize is that the charging rate isn't just bad for the battery if you charge to fast, pulling to much power in to charge the battery, especially while using the phone, creates a heat problem as well. While the phone will shut itself down before any major damage can occur, why would you even want to create a situation that could potentially damage the phone hardware?

not sure if this is just a coincidence, but I did something by accident that has has improved my battery life. After trying many tips and apps like Battery Dr+ and with modest results. I tried charging with the HP touchpad charger that I recently got. It puts out higher voltage than the standard USB AC adapters. To my surprise , my battery charges super quick and holds a charge even better. Again, it could just be nothing, but my Triumph is experiencing extra battery life as well from the touchpads charger. Just thought I'd throw it out to see if anyone has any thoughts on it.

USB is 5V, so I'd like to know how it is putting out more than that without damaging anything. Also, as I've stated numerous times (does anyone ever read around here?), the amperage output listed on the charger will have almost no effect on how fast the phone charges. The only time it will affect it is if the output amperage is less than what the phone will accept and the charger will limit output, but I doubt any charger with a power output below what the phone will take would be complex enough to do that.
Your phone will detect if you are getting power from a USB port or the stock charger. It will accept higher current with the stock charger. If you are charging from other charger, it will charge slow. To fix that, buy a new and cut open your USB cable. Short the 2 data cable.

The stock charger is rated at 5.0V/1.0A.
What is the HP Touchpad charger rated at?
I too have an HP touchpad and have noticed quicker charge times. Not sure about battery life though since it varies on my use. I cant use my samsung charger to charge the Touchpad, it says its not powerful enough.

from what i read, the HP charger is 5.3/2.0 Amps.
Not really sure why this would make a difference, since usb voltage is standardized and the kernel controls how much amperage goes to the phone. I once thought my Gtab charger did this, but imnuts pointed all the above facts to me.

Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.
I use an application called "charger report" which can display current consumption and Xtar "USB detector" device. They both show the same numbers. But Xtar USB detector can detect voltage of a charger. The charging current of LG g pro 2 is 1.4-1.5A when the smartphone is not used and higher when I use it. Using USB detector I found out that this smartphone can charge with maximum current a charger can give only if the charger's voltage is 5.3v. So it chargers at full speed with original charger and two other chargers I have: a charger from my Lenovo s6000 (2A 5.4V) and from my Asus t100 (2A 5.3V).
i tried that app too and got the same results as with Current Widget.
i'll buy a "usb detector". thanks.
I forgot to mention that it take approximately two hours for charging indicator to reach 100% when the smartphone reports that it fully charged. And it's necessary to left it connected to a charger for ten to twenty minutes to be really fully charged. Otherwise charging indicator will soon drop to 90%. One can tell if a smartphone is still charging by touching a charger or by looking at current consumption: a charger would be warm and current would be higher than 200mA.

Hey ray-lee!
I just bought this phone and as it seems it could get someday similar problems as my former phone the Galaxy Note 2.
That phone has had problems with charger and cable also. I had to buy another set of charger and cable since the original ones gave up a few months after i purchased the phone (it was used). The cable managed only 500mA wich is very slow for a battery that strong. One night was once not enough to charge my phone from 30% to 100%. As it seems it is problematic to manufacture cables, that can hold up and continually grant the 1,8 A that would charge our device in just 2 hours. I read somewhere that the G Pro 2 is one of 5 devices that has blazing fast speeds on charging the battery. If you handle the cables with caution hopefully you will not encounter problems. If so my guess is, that you will have a hard time in finding a cable that can hold up. Sadly the stock cables are always more expensive. I do not get it, why companies dont build travel adapters that only charge ur phones built solid with sturdy cables to ensure the transmission of high currents. That way with charger + usb cable is just stupid, even when tis is an all in one solution.
I like this phone very much and i hope, that the cables will not be that sloppy as the cables that Samsung had/ still has. With Current Widget i get readings around 1500 mA (1,5 A) when connected to the stock charger. And yes the LG Charger is an 1,8 A one. I have also flat pins, but received an adapter to be able to connect it in Hugary.
Just sharing thoughts here, that will maybe helpful to someone...

i "think" as long as device has snapdragon it is Quick Charge enabled
I use the "Charging Report" app on my phone, and it reports proper values.
(Around 1500mAh with the LG charger, and around 1600mAh with the 2.0A Samsung charger.)
If your phone is charging slowly, check the CABLE. Cable can broke too.
(Many people complain about their Samsung charging cables, because they just stop delivering power after a while and just charge the device slowly.)

To achieve full charging speeds, a Quick Charge 2.0 enabled device must be paired with a Quick Charge 2.0 certified adapter
I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

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:

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.

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.

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.
