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...
Hello *@*,
I intentionally discharged my GN to a battery level of 1% today to record the charging time just for myself. Then I thought: why not make a graph out of it and share it with XDA?
Total charging time (1% to 100%): 142 minutes
Level checked at 0, 30, 60, 90, 120, 125, 130, 135, 140 and 142 minutes
WiFi On, 3G On, Sync On, Screen Off, no calls/msgs/notifications received, phone not used except for % check
1750 mAh Samsung stock battery & charger
Stock or extended battery? I've noticed my charge time varies wildly. Most of the time it's on par with what you've listed here, but every once in a while it goes up 30% in like 20 mins.

All capacitors acts this way (a battery is also a capacitor) the charge/discharge is always fsstest to 63% both ways and after that it slowes down.. this can ofcourse be monitored and controlled with soft or hardware. But this is the reality of capacitors

isnt it bad for the battery when it is not designed to receive charge that quickly?
All about charging LiIon batteries: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
TL;DR:
LiIons are charged in two main stages:
- stage 1 with constant current, that's the fast charging rate for (roughly) the first 2/3 of the batteries capacity
- stage 2 with constant voltage and a tapered charge current for the last 1/3 of the batteries capacity, that's the slow part where the graph flattens
This is necessary because a LiIon battery is full at exactly 4.20 V and can not handle any overcharge. In fact at ~4.55 V (only + 0.35 V!) the battery would "vent with flame" aka explode.
If you wanna do this on purpose, this is what will happen: http://www.youtube.com/watch?v=YCWdnjLqVWw
Using a more powerful charger can work if the electronics inside the GN handle the higher current properly. I wouldn't recommend it, though. It may charge quicker but it will wear down your battery faster as well.
The phone can only draw up to 1A regardless of much higher the charger is.
So if you're buying a charger, don't bother paying extra for a 2A, but there is no harm in using a 2A charger if you already have one.

Stock charger is 5V/1A (=5 watts). There may be some leeway built into the GN's charging electronics so it can utilize more than 5 watts, but you can safely assume that Samsung would have packaged this phone with a 10 watt charger if it was safe (or desirable in terms of charging time vs. battery durability). Charging time is an important aspect after all.
The phone can absolutely handle it. I think Samsung is just too cheap to give us a rapid charger, I mean there was enough space in the box.

My car charger is a 2amp charger and does approximetly 1 percent a minute. At home I connect it to my HP Touchpad charger and it seems to charge really quick.
But I LOOOOOOVE my car charger as it can charge my Tablets and phones fast. Well worth the 30 bucks I spent at Best Buy for the rapid charger.
surely a 2amp charger is capable of providing 2amps, but if whatever is attached only drawers 1amp then that's what it'll get ? It doesn't force 2 amps down it's throat ? My palm pre 2 charger is 1amp, my touchpad has a 2 amp charger, but my palm pre doesn't charge any quicker using the touchpad charger.
My Gnex does charge really fast using the plug that came with it especially coming from galaxy s2 which takes ages for a full charge.

FYI, 1% a min is roughly 1A.
In 1 hour, it would restore 60%, 60% of 1.750A = 1.050A.
Nexus battery is the perfect size to eyeball the inflow rate.
30%/hr = .5A
60%/hr = 1A
60%/30min = 2A
If you think you're charging at 2A, simply time it. Also these are rough numbers and will only be accurate when the battery is low.
I searched for a solution and bought these two items..

http://www.amazon.com/gp/product/B009W34X5O/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1
Now here's the kicker... It's currently unavailable...but two days ago when I wanted to make this thread is was not even listed on Amazon, so possible restocking ? I don't know.
I killed my battery to the point of total shut down by about midnight Saturday night. When I got up about 930 am I was fully charged. Now I know we've seen longer run times leaving the charger on after 100% pops up, so to speak to that I am on 94hrs run time and have forgotten how to check Screen On Time...
I am now at that dreadfully annoying -10% level. So I can use the phone all day on 100% brightness but it will chime in all day to warn me of the coming Powerpocalypse to come :laugh:

If you rooted your device you can put an xposed module on that will eliminate all low battery warnings.
On your setup, I don't really see the difference between it and using the OGP's standard high-power charger. The cable isn't going to do anything, as far as I can see. And the charging port is 8A/5 ports — from what I've read it adapts to the device to allow it to pull what it needs within that allotment, thus I don't see the OGP pulling more than 1.8A. So, my question to you is, you've tested the standard 1.8A charger against your setup and you get X hours reduction on charge time?
FYI, I don't have the ZeroLemon pack. Thinking about it but might upgrade my device to the GP2.
I have, it took a day and a half.

36 hours to charge?
Most using this pack state around 12 hours. Seems something is wrong if it's taking 36 hours to charge with the standard charger that comes with the OGP — normal battery charges in less than 3 hours. I've seen where some zerolemon packs hit 100% but are actually only half charged, thus causing increased charge times. . . . strange stuff.
Using Yoobao 2 Amps wall charger
My zerolemon (9000 mAh) only took 10 hrs to charge. And standard battery (3140 mAh) took 2 hrs using Yoobao 2 Amps wall charger.
I was hoping someone could tell me where to find 4A or 5A wall charger near Jakarta.
My zrrolemon zero lemon takes about 12 hours to charge AMD my standard battery takes about 2-3 hours using the stock charger

Hey guys,
I was wondering if anyone tried this on the M8.
I used a nexus 7 charger for the M8, I didn't check if the charge time was faster because I plug it before I sleep but the weird thing is that the
battery life is somehow significantly better and lasts longer.
On my old ONE X, if I used the nexus charger, it would charge the battery faster but it will also drain quickly. I read also that using a tablet
charge (2A) will damage a phone battery on the long run.
I dont know if this has to do with the snapdragon 801 or the quick charge technology? or am I just imagining
what are your thoughts?

Funny you mention this. Wether or not its relevant (Not trying to debate the fact), I like to "condition" my phone batteries when I first get them, full discharge - recharge while turned off for first 3-4 charges or so. But I did in fact use my Google Nexus 7 charger to do so, and on the 4th charge I got 6 days 8 hours before charging on light usage. Minimum 1 hour talk time per day via 2 30+ min calls, and 20+ texts a day. (Light facebook / game usage for the sake of seeing how long it will last) Not sure if it has anything to do with the way I charged, or the charger, but I'm pretty happy with it. Just on reg power saver, as you can see the Sprint version did not have Extreme power saver update yet.

WOW, 6 DAYS now thats great!!!
I think it because of the nexus 7 charger
Ok, some facts:
Qualcomm quick charge 2 will allow very quick charging (around 1 hour), but there are no chargers yet.
Conditioning your battery hasn't been required since we moved to Lithium ion, 15 years ago.
Using a charger capable of delivering more current won't make the battery draw more current, in fact, with HTC, it might draw less (the device checks the data pins are shorted to detect a mains charger). Thusly, it won't affect the longevity of your battery.
Using the nexus charger is highly unlikely to have increased the charge in your battery, or reduced the power consumption of your device. If it lasted longer, you used it less.

No its not. Especially when your using the phone and its on 5% plugged in. Takes forever to reach 6%.
I'm having literally no issues with charging from dead to 25% in about 15 minutes. 2 hours to 100% im very happy with the speed of charging and this is using my m8 charger as the m9 one is still sealed in box.

I've been using the GS4 charger, with a high output cable. The Samsung charger is 1.5A where the HTC m8/m9 charger is 1.0A
the supplied charger is definitely giving 1.5 amps to mine. charges up pretty quick. with a quickcharge 2.0 charger it's crazy fast to charge.
One thing to note is it will take a faster charge the lower the battery level is, which means more heat. if you're also gaming with it, you could be bumping against the battery charging cutoff temperature. I only ever saw this happen on my Tegra HOX+. IIRC HTC has the notification LED blink in alternating green and orange/red when this happens. I'm guessing you would have mentioned temperature in the OP if this was the case, but I figured I'd bring it up.

Sorry, meant it was 1.5a for HTC and 2.0a for the Samsung one. Didn't have them on hand to check.
iPhone 5 battery is 1,440 mAh... M9 battery is 2,840 mAh. 50% charge of Iphone battery doesn't equal 50% charge of M9 battery, in terms of charge time.
I believe the rate of charging to decrease while you use it to prevent the phone from overheating. (My M8 does this as well)
My stock charger is fast, and my quick charge 2.0 is crazy fast.

Yeah, this. I got an HTC Rapid Charger 2.0 for it just to be sure since I knew with certainty it's Quick Charge 2.0. In retrospect perhaps not the best move considering I'm essentially incentivising HTC for not including one in the box from the get go, but whatever.

Yup i got the same issue gonna take me 6-11hrs to charge and its very slow charging
I had a similar problem to OP. The second night I had my phone I plugged it in at 11 pm with about 5% battery left and went to bed. At 5:15 the next morning (6 hours later) it was only at 85%. I can't tell if there's still a problem or I just think there is because I'm paranoid about it now. I haven't run my battery down that low since, and looking at the charge current with Ampere seems somewhat inconclusive. I may have to run it down and then keep an eye on it while charging to see what's going on.
Something IS wrong with SOME M9 phones (I think)
I have one of the "bad" ones. Mine takes hours and hours to charge, whether on the cable and plug that came in the box, or on any others that I have around - some I know are 2 Amps. I think there is something seriously wrong with some of these phones, based on what I am reading in this thread, and on my own example. I have had my M9 for just a few days.
I'd like to post a follow up to this thread after having the phone for a couple of weeks now.
I've had several occurrences where my phone didn't fully charge overnight. The worst was a few days ago, I plugged it in at 5% and the next morning (6-8 hours) it was at 1%, it actually lost charge. I noticed before unplugging it so I looked at the history in Battery Widget Reborn and it showed the battery level just slowly dropped from 5% to 1% without any jumps or dips. The battery icon at the top of the screen showed it was charging but it died at that point so I didn't get a chance to open Ampere.
I think it's the charger (and/or the cable) that came with the phone. I've tried several other chargers that have all worked reliably:
- The QuickCharge 2.0 charger that came with my wife's S6 charges my phone really fast.
- I have a Kmashi external battery that also seems to charge it relatively quickly.
- Two older chargers that are several years old (both rated 5 volts at 0.7 amps) charge it from around 30% to full in 3-5 hours.
At first I thought it might have been a wakelock problem, but the battery has been dropping so slowly when the phone is just sitting in my pocket that I'm confident now that it's not wakelocks. I don't know if HTC is likely to send a replacement, but I'm going to stop into the Verizon store that I got the phone from to see if they'll replace it.

My phone is also odd when charging.
Half of the time it takes 6 hours or more to charge. If I look at GSAM battery monitor it shows a charge current of around 350mA. If I then unplug the charger and reconnect after 15 seconds I get over 1300mA charging current, most of the time. (It takes GSAM a while to show an accurate reading). Occasionally it will take a few tries to get it right. Once I get a good reading over 1300mA the phone will charge in 1.5 hours like it should.
Something very buggy about this phone's charging circuit. I get the same behaviour with all chargers and cables, even my battery bank.
