So I just ordered this charger and it charged my phone from 4% to %100 percent in exactly 3 hours!
http://www.amazon.com/gp/product/B0051ZJA64/ref=oh_o00_s00_i00_details
Wow, what a great improvement over stock which takes 6+ hours. This makes me believe, that even though the stock output is rated at 1000ma and this charger's output is only rated 700ma that this charges works correctly!
If you have a 1800mah battery and you charge it at a rate of .7A, it should take it exactly 2.57 hours to charge, (1800/700). With stock it should take less, because 1800/1000 = 1.8 hours, but it takes 6+ hours to fully charge! Something is f'ed up with the stock charger or phone's software...
Yeah. About that. I just got my E4GT yesterday and noticed it does charge extra slow compared to my O.G. Epic.
My wife stayed with hers, maybe I will try charging my phone on hers. I wonder if that would make a difference...

At first my charging was extremely slow but now it'll charge from 2 to 100 in under three hours

I use the Palm charger from my TouchPad. Will go from dead to fully charged in about an hour and a half.
What's you TouchPad charger's output in mah? I think I might have to splice into a spare USB cable and check how much current is actually used by phone when on stock charger...pretty sure it is nowhere close to 1000mah.
2000mah is the output from the TP charger.
According to BatteryMonitorWidget, it estimates avg mA charging at 270mA using the stock charger that came with this particular phone.
I have my original charger from my Evo 4g and have noticed that it charges my phone a lot faster then the stock one that came with the phone. :-( weird

That sounds about right! I'll see if I can test this with my AMP meter tonight and tell you all for sure on stock vs new samsung charger that I've got.

Yeah, at 2000mah it should charge in less than one hour...I would say your actual charge current to be around 1200mah...
i would be careful with these chargers.
i have dealt with a lot of Li-Po's in the past and there was a formula to how fast you should charge them.
i imagine it is the same deal with Li-On.
charging outside such formula could kill the life of your battery or worse.
Seems like i must have gotten lucky as a ton of people are having problems with their phone or chargers.
I just charged my battery from 0 to 100% off the stock charger in 2 and a half hours and i also havent gotten any of the dodgy input problems using the phone while charging.
I went back and took a longer look at the battery history when charging. When starting the charge at 65% it starts off around 828mA, then 540mA, then 360mA, so it looks like (as expected) the phone knows how much current to pull to charge the battery safely and it adjusts based on how full the battery is. Not saying it does this for the charger included with your phone, but that is the behavior for the charger included with this phone.
These are all estimates provided by Battery Monitor Widget because there is no real-time mA current meter in this phone (according to the author)
Ordered one of these. Stock charger takes a lifetime to charge the phone.
My GF got Nexus S 4G and it's stock charger also takes 6+ hours to charge, so there's something wrong with the chargers I guess...
The pins on this charger must me different than the stock charger. Just because the stock charger is rated up to 1Ah doesn't meant the phone or batteries circuitry allows that much output. The resistance and length of the USB pins on the cable are what determines the output of the charger. Simply using a different USB cable with the stock charger will get you faster charge times.
Using a 2Ah charger will get you nowhere, the circuitry doesn't allow that strong of a current. Just a bit of an FYI. Save your money and save your phone, use a different USB cable.
Also, how is the charge time holding up? I doubt you're getting a saturated charge with that charger.

Ive dealt with 1,2, and 3 cell lipos ranging from 150mah to 5000mah, and every one of them either say to be (or ive been told its recommended to do so) charged at 1C. so a 500mah battery should be charged at .5A, 1000mah at 1A, 5000mah at 5A, etc...
my lipo charger displays a bunch of info as the battery charges and it definitely drops the current as the battery gets closer to being fully charged. if its the same with li-on then I would imagine that .18A should be the most you would charge this battery, but Id rather it take a long time because unless things have changed recently, doesnt the slower you charge the battery prolong its life cycle as well as extend how long it lasts each charge? I only charge mine at night when I am sleeping so who cares if it takes longer than an hour. if I get into an emergency situation I have the cig lighter charger and in the worst case I even have one of those crank flashlights I can use to charge the phone in the event my car battery shorted out or something...
Hey guys,
I've used my HP touchpad charger a couple times now and it seems to drastically speed up charging. I thought I'd see if anyone else had experienced this as well.

I would not recommend using tablet chargers like that. Although it does speed up charging I think you might also wear out your battery quicker.

That's not right. The charging speed is limited by the battery and their charging managemend, not by the charger. If the battery management is configured at 1A it is charging with 1A even if you use a 2A charger.
If you can charge the HTC One with a bigger charger faster than it is not negative for the battery because it's allowed by the battery management. But I don't think, that it is really faster. I will test it for myself later with the 2A Charger from the ipad.

I do know where this is coming from but just isn't the case anymore. All batteries made for cells phones in the last 2 years have smart charging chips in them. Meaning they can not overcharge, charge too fast, or discharge too much. These batteries have tech built in that could charge them in about a hour. People think this was disabled to help prolong the life of the battery. This is also false. Fast charging does have a slightly negative effect but we are talking about 2% negative. So if the battery would have went through 2000 charge cycles normally than with a fast charge it would only last around 1180 charge cycles. It's a non difference. It is the reason people have been saying that the fast charge feature is disabled but they have no idea and it sounds good so the community here has decided it to be true.
Now technically it should not matter what amp charger we plug in as the phone should only take a certain amount. Now I know this is false as I also use the 2amp Touchpad charger and can confirm it does charge around 30% faster.
Can someone explain why the power capability of the charger makes any difference?
Rules of electronics. V = IR or in this case I = V/R Current = Voltage / Resistance
By definition if too much current is drawn from the power supply the voltage will collapse. Similarly, at any given voltage and input resistance, the current will never exceed a certain level.
So the worst that can happen is you damage a power supply trying to charge a greedy iPad with an under spec'd power supply.
But I see certain devices that say, never use a 2A charger as it can damage the device? Why? By definition it will never draw more current than the circuit is designed for.....what am I missing?

Nothing at all :cyclops:
Now if you use a .5 amp you do run the risk of burning it out as the device will try and pull more than .5amp and will succeed putting too much strain on the charger.
AFAIK the charging voltage/amperage is dynamically controlled by software(kernel). Starting from empty the voltage will be higher, but decreasing when battery is getting fuller.

The voltage of the power supply should be a controlled 5V (I know some poor supplies are not so perfect). The only way of changing the current being drawn is to change the resistance , but that would be a constant as determined by the battery itself (its current draw will change depending on how full it is at the time). If there was actually a charge controller circuit in the phone itself, then it should not matter whether you have 2A, 5A or 50A, because it should only ever draw the power it needs. Also if there was effectively a "short circuit" and you tried to draw 2A from a 1A power supply, the power supply voltage would collapse and charging would simply stop. Therefore the charging circuit will have been designed with an expected current flow. As voltage is 5V and the input resistance always remains constant, the charging current can never be more or less than what was intended by design! Of course if the power supply outputs 10V instead of 5V, then it WILL draw more current and do lots of damage!
Think of it this way. If you run at 5 mph, it doesn't matter whether you are 3 feet tall or 6 feet tall, you will still arrive at the destination at exactly the same time.
There are different cables that can be purchased that essentially have just the positive and negative connections in use. This removes the control connections that allow the phone to regulate the amount of power so it allows the device to charge at a faster rate.
I have used these cables for years on many devices and have never had a problem but it is worth noting that I only use them sparingly and the vast majority of the time I use the standard chargers that come with the devices.
MG
Stop with the FUD people, the only thing that matters is the voltage of the charger. It needs to be 5V or else it will damage the phone. Otherwise, the phone will self limit the amount of charge taken in.

Using a higher current charger will degrade the life of the battery faster than normal. It will also be hotter when chraging, thus further degrading the life of the battery.
Bear in mind USB2.0 can only provide 500mA and makes charging slower.
Using a 2A charger ON OCCASION will be fine, but long term use will degrade your battery, it's that simple.
fast charging batteries is not as good as slow charging for the batteries. It's not terrible, but it is worse for their health.
the smart chips in the phones are allowing to be faster charged = faster charge times. HTC probably allowed this because they knew it would pacify complaints about their slow charge.
The htc engineers saw it fit to include the charger they did, they know its charges slow, it's for a reason.

Your numbers are a little off i'm afraid. If its only a 2% issue from 2000 charges.. you show 1180 to be then new charge..thats almost 50%. 50% would be 1000 charges.. 2% from 2000 would be 1960 Better number for your point

Yeah it will degrade it quicker, but not significantly. I agree with the previous posts. Its fine to use a charger with higher amps than needed but its not good to use lower amps. (lower than 500ma) Lower amps will kill chargers quick. If usb is 500ma then these phones must be fine with variable amps (within its limits) I dont know what the variable numbers are but say its 500ma min, 2A max.. using a 3A charger or a 5A charger shouldnt make a difference in charge speed. It'll only draw 2A. (again hypothetical 2A here, 1.5 may be the max.) That being said... i wouldnt use a 2A as your primary or overnight charger though(unless you only sleep 3 hours ), no need for it..Since these phones dont have a replaceable battery your overnight charger should probably be 1A. Use a 2A during the day if you need a quick boost.

I used a Samsung 0.7A OEM charger for a while for my previous phones and always thought that the power is capped by the output of the adapter. If it's rated 0.7A the adapter can output up to what it was rated for; That is wrong on that assumption. Using Current Widget app also appear to support this as well as it was drawing on my S3, 0.999 mA when this adapter as in. I have switched to the 1A adapter because of that; the read outs using the app still shows up as 0.999 mA.

If using a higher one is no good like 2A, I guess we would be able to see what Current Widget saids as well. Supposedly the phone pulls what it needs to my understanding.

Wow, aren't you a helpful one. There is much more to the H/W selection than what the charging circuit is capable of... Chargers don't "force" a current on the battery. The charging circuit draws what it needs from a charger, assuming it can supply what is drawn. A well designed charging circuit will draw no more than what the battery is capable of without damage. The only factor is heat, which should be accounted for at a nominal level. If heat was't properly accounted for, or they short changed the charging circuit (like the charger) there could be an issue long term.
As an application side note, I had a 2 or 2.1A charger on my Atrix 4G for the 2+ years I owned it and still on the original battery that will last me an 18hr day. You don't do anyone favors talking about stuff you don't know anything about.

It's already documented that other chargers charge the phone faster. HTC included a slow charger for a reason. You don't know more about battery technology then they do. Fast chargers are like $5 for us on amazon. htc can buy them for a $1. There reason is not cost. Why do you think HTC inclduded the charger they did.
There is no perfect battery with unlimited recharge cycles no matter how perfectly designed. Fast charging won't cause you device to explode, but it will accelerate the regular degradation process.
Htc knew people would complain about slow charging, so they allow other chargers to charge the battery faster on case by case, even if it means degradation (slight to moderate) of the battery over time.
You read more about fast charging vs slow charging in the battery geek forums.

It comes from my own knowledge and experience. These are facts. If you choose not to believe them that's fine. And yes, I mentioned heat if you look back. And no, these are not properly designed systems.
The HTC One definitely takes a while to charge. What’s interesting however is that the charge curve gets the One to 85–90 percent under the normal 3 or so hours, it’s that last ten percent that takes forever. I also have confirmed that Qualcomm’s Quick Charge is not being used on the HTC One, for whatever reason, possibly to maximize compatibility with the portable USB battery chargers that are now proliferating. The PMIC is there, it just isn’t enabled. My guess would be that HTC wants to prioritize battery longevity and minimize any even potential extra wear since the battery on the One is sealed inside.

told ya =)
I've had my Nexus 5x for a couple months now, I bought it through amazon refurbished. (My girlfriend has the same device, she bought hers brand new. Her's is the international model though) Here's a listing of the charging cables, and chargers that I have:
Anker Quick Charge 3.0 and USB Type-C 24W USB Wall Charger http://amzn.to/2mitz3n
Anker A to C 6ft cable http://amzn.to/2lbw2HW
Anker 24W Dual Port Charger http://amzn.to/2mx16Tt
(I bought the a to c cable to be able to connect to pcs or whatever, and the charger i had for my Nexus 5 and other micro usb devices.
Standard Google Charger https://store.google.com/product/usb_type_c_18w_power_adapter
Obviously the middle item there doesn't charge at full speed, it isn't intended to. But my charge rate using any of those devices is still over all over the place within each of those items specifications. So it isn't likely that is a cable or charger issue which is normally the issue when someone has charging rate problems. yes i know the charging rate slows down as it reaches higher percentages to prevent over charging and other types of battery damage.
My phone can be down to 20% battery when I plug it in and it could start charging at 110mA or 2000mA+. Whatever rate it is though, it isn't going to stay that way for very long. If it starts low, then it might work its way up into the 700-900s slowly or to around 1000mA. If it starts up high 2000mA it'll likely start working its way down slowly into the 1000-1800mA range.
Sure charging at slower rates helps the battery to last longer, but when i have no control over this, and at times it discharges faster than it is even charging it is bad. I can actually deplete battery sometimes, if its charging while video chatting. Albeit very very very slowly, but still. The battery life and range seems to be very good aside from this charging issue. The connection port on the phone seems really quite solid as well and wiggling the cord doesn't seem to affect the charge rate as best as I can tell.
My girlfriends 5x charges in about half the time that mine does, or sometimes its even worse, i just have to pay attention to what it is doing when i plug it in. So my question is, is this a battery problem or is there something else going on with the phone? What is it that throttles the charge rate down as the battery % gets higher? Is there a chance this could be faulty and causing it to be all over the place like this? Any ideas about this would be very helpful thanks in advance.
Ps: I really do love the device, it works great, I have no issues with it beyond the charging rates that can be all over the place. I can go from 10% battery to 75% sometimes in half an hour or so. Then i get times where it takes well over an hour for that much.
(I use ampere to measure the charge rates)
Charge rate goes down with higher battery temperatures. Let the device cool down a bit before plugging in, also keep the screen off to allow it to charge at full speed.
The charge will also slows down as it fills up, the last 10% will take the longest.

I appreciate you taking the time to respond, since you are the only one thus far. But as I said I'm aware of the charging slowing down for those reasons, and I've got another device to compare to. It isn't the same, and the device isn't hot.
There is no problem with your battery. The phone is badly designed. Unfinished SoC combined with a small battery and a big screen. Your money is better spent on something else.

OK, a serious question:
1. Charging speed is affected by Charger (the thing that plugs into the wall), the Cable (how long or thick it is), and the Battery (how hot, how full it is). This is the basic, moving on.
2. Sometimes the C port is buggy and doesn't correctly detect the maximum amount that a cable+charger combo supports. Download Ampere or some other current measuring tool like GSam (although I never bother with GSam, Ampere is awesome), and make sure the max amperage is 3000 mAh. Anything lower than that means you have a low-powered charger, a less-than-optimal cable, or a hot or near-full battery. I recommend plugging it in at around 50% to make sure the near-full charge speed drop doesn't affect anything during your tests.
3. If that doesn't work, replace the battery. Final line advice.

Hello!
Charging problems started to occur a month ago on my phone. The problem is that it charges really slowly, but other times normally.
I experienced that if I plug in the phone when the battery is between 20-60% it charges super slowly.
Sometimes it speeds up but more often not.
Here are some screenshots that show that sometimes it takes like 6 hours to charge and sometimes it basically just hovers around a percentage and doesnt do anything. Gets like 10% overnight.
On the second picture you can see that it charges normally till it reaches 55% then it slows down to like 5%/hour speed.
I noticed this while the phone was draining battery even tho it was plugged in while using it.
I bought a new OEM battery and its the same with it aswell. Some chargers charge it quicker, some slower, but the problem occurs with every charger.
What do you guys recommend me to do?
Thanks a lot!
is your charger 2 Ampere as it should be?
U can also try to recalibrate the battery deleting the data/system/batterystats.bin file

Actually brother initially same problem occured with me and it was persisting on the same way load since i come to change my charger now before i was charging it with blackberry passport charger it was really cool and even charges it faster that i mean around 50% faster than the previous charger, but now days m befitted with moto g4+ which meets to charge my lg g3 around 65% faster
But brother dont use any local company pr anypther charger as it may damage the phone display which may come to cost you at high
There are going to be 3 main factors that you want to address:
- Battery
- Charger/charging cable
- Software
It seems you have already addressed your battery. That's usually the #1 culprit, but you've already replaced it so you can rule that out.
The next is the charger and charging cable. This is often overlooked. The stock charger is 5 volts and 1.8 amps (5v 1.8a). Before more advanced smart phones were developed, almost all USB chargers never produced more than a 5v 1.0a charge (most were 5v 0.5a). So you want to ensure you are using at least a 5v 1.8a charger. (I even use my Fire Tablet charger on my G3 which is 5.1v 2.2a, and that works great too). Note that all USB chargers have their output volts/amps printed on them somewhere (usually in very tiny print). The USB cable you are using matters too. The thinner the wire gauge and the longer the cable is, the less power is transmitted. For example, if you're using a thin and cheap 6 foot (2 meter) USB cable on a 5v 2.0a charger, you may only be getting 1.0a of charge from it. If you use a thicker, shorter, and more expensive 3 foot (1 meter) USB cable on that same charger, you ensure you get that full 2.0a of charge (or close to it). The two factors to look for in a USB cable is length (length = resistance = less amps) and wire gauge (not insulation thickness).
The last is software. If you have any way to backup and restore (ie nandroid) your ROM from recovery, I recommend doing that first because it's easy. If you backup your current ROM, factory reset, and the issue persists then you know its the charger/cable. If the issue is gone, then you know it's something in your current ROM. If you do not have access to backup/restore features and/or do not have root, then next you can use the Android OS Battery stats to carefully go over what could possibly be draining so much power when the phone is on or off. There are also several apps that will help you determine where the battery drain is coming from. Note that software can not prevent your phone from charging, but it can drain power so fast, that there is not enough left over to charge the battery. This is especially bad for our G3s because they easily overheat if they are charging and heavily discharging simultaneously.
Hope that helps! Good luck! :fingers-crossed:
According to Ampere, the phone is charging at 1100mah and 4v with the factory cable and adapter. Battery is at 20% when I started. Are those numbers right because It seems like the fast charge should be higher. It does say "Fast charging" on the lock screen.

I don't have the p2xl...I have a 6p but my phone starts off allow when fast charging with the OEM charger. But after a couple minutes it ramps up to around 2200mAh..... It's like it had to warm up a bit...... Does yours do that?

That's not fast charging and no, that's not ok.... it looks like the charging rate may be capped at 10.5W. If true, this is not cool.

This topic has come up before. Personally, I don't think the app is reading the actual input. If it was measuring somewhere on the input line it wouldn't show the discharge rate when the charger is disconnected. So wherever it is measuring is not designed to measure what is coming in from the charger. Fast charging is 9v at 2 amps. There is probably some special circuit getting it to the battery and not into the phone guts, which are running at 5v.
If you have doubt that it is fast charging, just try timing recharging time with different adapters.
On Ampere, mine shows 5v at 1 amp for every charger including stock, other than a 1 amp charger. For that, it'll show 4v at 1 amp. But the actual charging time with the stock charger is much faster than using a 5v at 2.4 amp charger. If you get a similar recharge rate with a 1 amp charger and the stock charger, then Ampere would be correct. But it should be a much different recharge time.
If someone uses an inline module in between the charger and phone, then that'll get my attention. But I haven't seen where someone has done that. Supposedly someone has done that, but no one has linked to any post in the prior thread about this.

Ah, so you didn't read the linked XDA article by Nathan K. but commented in this way?
Ampere is giving you the charge with your battery drain. You're supposed to measure what your drain is in the app without plugging in the charger, then add that to your measurement when you plug it in. You will be somewhere around 1500mah at that point (400-500mah drain).
That is because android limits your charge rate when the screen is on to 1500ma. Your phone will charge faster with the screen off, that is for the thermal throttling. Ampere can't measure with the screen off. Use accubattery to see that, you'll need to leave the screen off for 5-10 minutes to get an accurate reading.

No. I have no idea who Nathan k is. No one has pointed me to wherever he posts. They just keep telling his name as if everyone knows who he is. Paste a link.
Edit: Here's where I saw it before, and I did try to find him on Google +. I wasn't told there was an XDA article.

Ah okay, well the link to "capping" was in my post just above, but you probably missed it. See the article here. As for who he is... he has been taking over for Benson Leung in testing all things USB-C. His G+ link is in the article. He does a LOT of testing and publishes his findings. :good:

Ok, thanks. I know about Benson Leung. I had seen the orange color in the text, but in my brain that was highlighting and not a link.
I stopped using the stock charger after about 5 days because I worry about heat and things like the 6P battery issue. But it seems like I don't have to worry so much if they've dropped the charging current for the whole charging time. That also means I can keep using my old 5v at 2.4 amp or 2.0 amp chargers during the day and not miss much since it is going to be charging at about 10 watts either way. It just won't have a few minute start at higher watts. At night I use a 1 amp charger.
I don't blame Google for dropping things down since the 6P is said to have charged at 15 watts and the dying batteries cost them a lot of dollars replacing user's phones. Project Fi even started sending Pixels as replacements when they ran out of 6P refurbs until corporate stopped that practice.
But they do claim "Up to 7 hours of battery on 15 minutes of*charging". Wonder if that was before or after they messed with the charging current. If I wasn't on Project Fi, this would be one more reason not to ever have considered this phone to begin with. I almost never need to rapid charge and then go somewhere away from an outlet, but other people do. I was also forced to buy an external battery since the 5X battery life sucked. So I do have a backup.
