Sarcasm, haha laugh a little.
But really, do you guys notice that it takes a long time for the battery to charge?
I think when available, I'll buy a bunch of batteries just to have handy.
well the battery is 1500mAh the nexus charged pretty quickly but it was 1400mAh i am not sure how much difference 100mAh will make on charging the battery but that could be a possibility.
Charging with the computer will always be slower, if that's what you're using.
I wonder if its the charger. The provided charger has an output rating of 0.7A. I know some microusb chargers I have seen are rated as high as 1.0A. That could be the difference.

Interesting...that could be. However, maybe it's 0.7A for a reason? Perhaps the battery needs to have it at that "flow rate." ???
We did get a different charger over the i9000, they had a separate USB cable and microUSB wall charger. We obviously don't have that setup.
Some phones have Li-Pol batteries and they have to charge differently. This could be why it's taking so long to recharge.
check a tmobile store or website for the new portable micro usb charger. charges your phone on the go and recharges itself via a usb charger the vibrant ships with or your computer. i got mine and was a lifesaver the other night when i needed to leave my house with 10% charged.
I hate saying this, but: I literally LOL'd from the title of this thread.
I completely agree. Charging takes fuggin' forever. My guess would be that turning the device off helps speed this up, tremendously. But of course, who wants to do that?
That said, battery life has been impressively long, provided you turn off Samsung's widgets. :/

That would be a huge design oversight if a generic charger caused problems with the battery. I'm sure Samsung thought about the user charging with a generic charger.

How fast is fast, iceshinobi?
I have conditioned my battery twice and going from empty with the phone off and pluged into the wall not via usb-pc, took me over 4hrs each time.
If the charger is 0.7 going to a 1.0 would be a huge improvement. The only worry would be the extra heat and problems that might cause. With NiMH batteries quick charging is preferable to slow charging, is this the same for Li-ion?
came here for insight as well, woke up at like 5am, phone was almost dead, 10% battery or so
turned it off, plugged it in to the wall charger and it is now 8am and it is maybe 60-70% charged
what the hell?
with my g1 turned off i can go from 0 to 100% charge in like an hour or so using a USB port. now i know the battery is smaller but c'mon... this is ridiculous.
Could it be that the phone just has to break in? When I first got G1 it would take about 4 hours to charge I remember, now a year and a half later I can get it to 80-90 percent in 1 and a half.
The computer USB standard is 100 to 500 milliamp, the USB walloulet adapter (charger) Is 700 milliamp, our batteries are 1500 milliamp and that's why.
USB cables have a certain standards witch includes voltage and current standards.
If you want a fast charger look for a hard wired 1000-1200 milliamp charger with a micro USB connector on ebay.

Hi all,
Ok, so I finally managed to order a 16Gb Nexus 4 and hopefully it will be with me in 1 week or so.
And I was wondering one thing regarding the AC adapter: I believe (pls correct me if I am wrong) that the original AC adapter’s output voltage is DC 5V, 1.2A.
I will need an extra AC adapter to keep it at work and I was planning to use one of those:
- The Sony Xperia P AC adapter will output 5V, 1,5A
- The Samsung Galaxy S AC adapter will output 5V, 0,7A
It is clear that neither of those 2 chargers will match exactly the specifications of the original Nexus charger (same voltage, but different amperage).
So, here goes the questions:
1) Is there any problem if I use a charger that will output the same voltage but with different amperage?... if not, which one would you use and why?.
2) how the amperage affect to the charging process?.
Thanks all in advance
PS: sorry for terrible English
You can use any charger up to 2 amps.

You must use a 5V AC USB Adapter and better no LESS than 1A
for Fast Charge.
AC Adapter I Use:
iPad AC Adapter 5V 2.1A at Work
PlayBook AC Adapter 5V 1.8A at Home 1
Original Nexus 4 AC 5V 1.2A at Home 2.
Our Nexus 4 will Draw around 0.8A when Batt lever at 0% - 80%,
then around 0.5A at 80%-95%, Final State 95%-100% will draw 0.2A roughly.
When 100%, Nexus 4 will use the AC power & the Current "A" show on phone
will like 2mA (0.002A) when idling.
** 1A = 1000mA
As previous poster said, do not go under 1.2amp.
I run the OEM charger in my bed room, a USB charger to my computer, and a 2.1amp charger in the car.

Why do you say not to go under 1.2A? Charging from a laptop is at .5A. I've been using a 1A charger since day one. Haven't experienced any issues with it.
Charging at a lower amperage shouldn't hurt anything, just charge slower. All you have to do is make sure it's a 5V charger. Amperage shouldn't matter but a lower amp charger will charge slower. As for a higher amp charger, the phone will only draw the amount of power it needs to charge so using 2A charger won't hurt anything either.
Also 2mA is 0.002A not 0.02 A

Since the charger doesn't actually regulate the charging itself (the phone does this) it doesn't matter how many amps it can supply, could be 100 amps, no worries. As long as it is 5V, the phone will draw as many amps as it needs.
Since the supplied charger is 1.2A rated, it's fair to assume that the phone will never actually try to draw any more than that, so there will be no benefit in going higher.
Going for a lower current charger will likely extend the charge time.
I use a 2.1 amp daily without any issues.

Wow guys!!... thanks all for your answers!!
So, if I understood correctly, the amperage will only affect to the charging time, meaning that by using the Xperia P AC adapter (1,5A) the battery will be charged faster that using the Galaxy S one (0,7A)... right?
Pls allow one last question: a few yeard ago, I think I read in some forums that a slower charging process could help to keep the batteries in the best conditions for a longer time... is this still true with modern batteries??
Again, THANKS all for your help!!

Yes, the .7A charger will take a little longer to charge you phone.
On the other answer, I think NO but I'm not as familiar with LiPo batteries. I would venture to say that .7A vs 1.2A (max the phone will draw but I think someone above mentioned it's even less than that when the battery is very low) is not going to make a bit of difference in your battery life.
One thing I do know about LiPo's is you do not trickle charge them. So while plugged in it will charge at the rates mentioned above until full and then it QUITS charging all together. Once the phone discharges the battery to a certain level, it will charge it back up again. Probably at 98-99%.
There may be one other thing to consider when selecting a third party charger. In the Nexus 7, the device looks for pins 2 & 3 (data) of the USB plug to be shorted in order for it to draw full current. If this pins are open (or have a load across them as is the case with iPhone/iPad chargers), the Nexus 7 will assume it is plugged into a computer and limit its draw to 500MA.
Not certain the Nexus 4 behaves the same way but would assume so.

I want to make this case clear. According to my Charging log,
Here is some key point.
Nexus 4 Max Draw Rate at Fast Charge Mode is around 800-900mA,
even you use a Charger that rated at 1A (iPhone Tofu), 1.2A (Original),
1.8A (Playbook), 2.1A (iPad).
Fast Charge Mode must be with Charging Cable with 2&3 pin Shorted,
or the charger itself have the 2&3 pin already shorted.
Therefore, 1A is a Sweet spot for getting Charger & Charging Time for
Li-Po/Li-Ion/Ni-MH Batt charging.
If you use under 1A Charger, eg 700mA or 500mA, it will take much longer
to charge the batt but no harm as well. Just too slow only.

Left a phone on a charger all night with a long (10ft) cable and it couldn't even charge the phone over night. I know a 10ft cable will slow things down but my gs2 plug has no problem charging my phone. Search around and you'll find a few fail stories about the stock LG charger.

I'm wondering if the heat I hear about being generated before the charging rate slows down after 50% would have any negative impact on battery life. Would there be any benefit in using my multi-port charger for overnight charges when I am not in a hurry to charge the battery?
Also, I assume that the battery doesn't have any memory, and that there's no reason to break it in, fully discharge periodically, etc. and that it's okay to charge a little or a lot regardless of the current charge state. Is that correct?
This is a question i would like to know the answer to as well
I did a slow charge last night and the battery seemed to discharge s little slower this morning fwiw, but that's not terribly scientific.

Fast Charging Lithium = Battery damage. It's basic chemistry. The cells take mechanical damage from expanding too quickly. So, for best longevity, charge her with like a .7 to 1 amp charger.

wrong. the only thing that damages cells is charging beyond the voltage specifications. How fast you dump electrons in has no negative effects, its only when you put too many in that batteries get damaged.

Thank you. I had thought the same thing. No one had the time to give me any detailed information, so I researched. I can't post links, but the following articles are helpful and will show up first in a search for the title
'Will speed chargers kill your battery?'
'BU-401a: Fast and Ultra-fast Chargers'
A conventional phone charger can only supply the current and voltage that is safe for a battery at all charge levels. In other words, it is must use the least common denominator. Quick Charge makes this process much more active by monitoring max current, max voltage, and temperature so that it can supply more power when it is safe and less power when it is not. Quick Charge will always keep the current, voltage, and temperature within the battery's designed specifications.
In terms of battery memory effect, no, modern lithium based batteries do not have any sort of memory-like effect. This is mostly associated with older and cheaper NiCad type batteries. This is one of those things that people seem to have a really hard time moving past.
People worry far too much about babying their battery.
Assuming you are going to use the phone for ~2 years then a properly designed fast charger should have a negligible effect on battery life. After 2 years of continuous usage all bets are off whether you used a fast charger or not.
If you really want to worry about how to treat your battery then there are two things you should try not to do. Don't let the battery go all the way to 0% and let it sit like that for a year. Don't leave your phone on your dash in direct sunlight everyday. Outside of those two things there's not much you can do to change the lifetime of your battery so just use the damn thing. =P

I had researched the topic and learned what you have stated, but I really appreciate you taking the time to write this fuller explanation. I wished to take every reasonable precaution to maximize battery life, given the battery is not easily replaced.
There have been references published claiming that charging faster (higher current) shortens overall Li-Ion battery life.
Mechanism may be related to heat.
One thing the Qualcomm Quick Charge 2.0 (used in the Snapdragon 808) does is increase voltage at the charger from standard USB 5V, to 9V and 12V, for higher charge rates (power) at still-moderate current (to keep heat dissipation down).
I measured 1.1 to 2.3 amps at ~9V with QC 2.0 charger on the MXPE, with the higher current measurements at lower State of Charge (SoC). Have not seen 12V yet, but I only tried it down to 45% SoC (2.3 amps at 9V), I imagine it bumps up to 12V when the battery is discharged further, nearer to complete discharge.
This charger is rated for
5V, 4A
9V, 2.22A
12V, 2.5A
20V, 1.0A
So the max power fed to the battery would be 28W (12V*2.5A).
(This is the Power Partners PEAW30-12-USB, supposedly a 30W charger. So much for integrity in advertising.)
So the current is kept to a manageable level to control heat dissipation (therefore max temperatures), from the charger to (somewhere in the phone). But I believe that at the battery itself, more rapid charging (higher power) would still require higher current, because voltages have to be limited in the battery itself, so one would think heat dissipation (> max temperatures) would still be a problem in the battery itself. Does that shorten battery life?
The answer is probably: Who cares. Because: Li-Ion batteries have a 2-3 year life in any case, regardless of their service life or even if they are not used at all. They age and exhibit substantial capacity decline over time. Discharge/charge cycles hasten the capacity decline, but the battery is only good for 2-3 years, give or take, no matter what. And since aftermarket replacement batteries are inferior, unsafe, and stale, there is no reason to try to hang on to your phone for more than 2-3 years in any case. (Especially since the "non-user-replaceable" batteries can be a pain in the a** to R&R. The Moto X Pure 2015 battery is one of those. Some phones actually incur permanent damage to seals if the battery is removed/replaced - the Kyocera Hydro Wave is this way.)
You say "but you could replace the battery with an OEM battery". There are two types of OEM Li-Ion phone batteries on the market that an individual consumer can buy retail, when their phone is 2 years old or more: Used stale batteries (look up "reverse logistics"), and "new" (i.e. not put into service yet) stale batteries. Good luck finding a fresh, new OEM Li-Ion battery for your 2 year old or older phone (out of production for at least a year).
Been down this road before. Wasted lots of time and money replacing phone batteries after 2-3 years. From now on I'm going to stop coddling phone batteries, stop replacing them after 2-3 years, and just figure on a new phone every 2-3 years. It's the only way to get a fresh, new Li-Ion phone battery. (And get the phone right when it is released, like the MXPE this month. That way you are more sure the battery is fresh.)
I think everything in the wireless phone paradigm is increasingly heading that way anyway. Everything, and I mean everything, pushes the market to a 2 year product life cycle. Batteries last 2 years. Increasingly, batteries are not made to be replaceable. Carriers are changing networks so fast you need a new phone every 2 for that alone. New OS/SW overloads hardware older than 2 years. Displays may fade over a couple years. USB connectors wear out. Just relax and go with it. Marvel at the Qualcomm Quick Charge 2.0 (I am). You'll be happier with a new phone every 2 years.
Sorry for the long rant.

Yes, the Moto Turbo Charger can be used with any MicroUSB charging device. It will adjust charging as needed for the individual device. Moto made the Turbo Charger, to be a single charger for all MicroUSB devices.
If the battery is kept well charged, which Turbo Charging helps to accomplish. That's better to me, than more drain and slower chargers that leave the battery more drained overall. The batteries are supposed to last longer when kept fully charged more often.

"...since Quick Charge 2.0 is compatible and interoperable, a certified adapter can be used with a non-Quick Charge 2.0 device, though the fast charging benefits of Quick Charge 2.0 will not be available. "
https://www.qualcomm.com/products/snapdragon/quick-charge/faq
By all appearances, Motorola's "TurboPower™ Charging" is nothing more than Qualcomm Quick Charge 2.0. (That's what Snapdragon 808 in the XT1575 uses.)
The third-party Qualcomm Quick Charge 2.0 chargers I bought are recognized as "Turbo" and function with the XT1575, just like the Motorola charger that came with the XT1575.
(There are a LOT of Qualcomm-certified QC 2.0 chargers for sale by third-party names. Qualcomm has been BUSY. )
To slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?

Moto doesn't have the option in settings, it uses industry standard Qualcomm Quick Charge standard rather than a OS hack like Samsung (no offense)... If it is connected to a QC 2.0 charger, it will negotiate the appropriate charge rate, if it is connected to a "standard" charger it will charge normally.
I don't think you can accurately measure battery/charge cycles... even if you could it would be extremely deceiving, what would be considered a cycle? Charging at 50%, 30%, 10%, and to what point 75%, 80%, 100%? Too much room for interpretation here that could be swayed either way depending on the person/app counting it's point of view.

Thanks for replying dear. So, for S7 I have turned off fast charge, should I now charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
For Moto G, the question is the same as above.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?
And I have signed your petition Brother. I hope they listen to the users.

Does Fast Charge hurt the battery life, no, at least not directly... heat does. Using an older style charger will avoid Quick Charging but I think that foregoing that benefit for a few more days of battery life is hardly worth it. I frequently have 30-60 minutes to charge, not 3-5 hours, so quick charge is nice, if it takes few days off the longevity of the battery so be it. Those who think it cuts the battery life by 20, 30, even 50% are wrong, that simply isn't the case because of Fast Charge itself.
The Moto G isn't an issue here, it doesn't support Quick Charge until the 4th generation, but why give up the feature?
I don't think the "rules" of charging apply as much as people think they do... I charge mine overnight and whenever it needs it during the day, if it does. There is no need to do anything special.

I frequently have 30-60 minutes to charge, not 3-5 hours, so quick charge is nice, if it takes few days off the longevity of the battery so be it. Those who think it cuts the battery life by 20, 30, even 50% are wrong, that simply isn't the case because of Fast Charge itself.
The Moto G isn't an issue here, it doesn't support Quick Charge until the 4th generation, but why give up the feature?
I don't think the "rules" of charging apply as much as people think they do... I charge mine overnight and whenever it needs it during the day, if it does. There is no need to do anything special.

Thanks for the wonderful and detailed reply. I am going to try, not stick, to slow charging to see the difference in heating of the battery. My SIII's charger 's input is 150-300VAC, 50-60 hz 0.15AA, output- 5.0V-1.0A and S7's details are input 100-240V 50-60hz 0.5A, output- 9.0V= 1.67 A or 5.0V=2.0A. Can I use the S3's charger to charge S7 after turning of fast charge or is there a voltage difference or something? G4 is at home, don't know about its details. Also in my country the battery or the replacement parts are way too expensive.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V30 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Honestly I feel like this is not quick charge 3.0 even though the 835 processor and the device supports it. The charger that comes in the box is only 1.8amps output. Compare that to 2.0amps output with my Galaxy S7 charger and even 3.0amps output on my Nexus 6P charger. So it's not really more than the standard 1.5amp output of most cell phone chargers today and less output than other chargers that come with quick charge compatible phones.
Over all it takes around 1 hour and 20 minutes to charge it from 20% to 100% with the charger it comes with. Keep in mind that's if you're not using it while it charges. If you are using the phone while it charges on about 70% brightness, then about double that time to charger from 20% to 80%. I might try with the Nexus 6P 3.0amp charger later to see if it makes any difference.
So right now I give this only a 6 out of 10 for charging. So 3 stars.

How did using the different charger workout for you?

Ran my phone down to 3%. Hooked it up to my QC 3.0 charger. Doing a timed 60 minute charge, I unplugged the phone at 82%
To be honest my last phone was a note 5 I just upgraded to v10 an I personally think that it charges just as fast, I put my my old samsumg fast charger to my USB-C an it registers at fast charging, charges while I play mmorpg, so GG I'm happy

I only tried it with a Samsung Galaxy S7 charger, which is
2.0 amp output instead of the stock V30 charger at 1.8amp output. So slightly more output.
It looks like no matter what charger you use above 1.8amp output, then the V30 is still going to only use 1.8amp charging rate. I think the phone is programed to limit it. Which is sad because I do not think it charges quite as fast as my S7 Edge.
When I plug the stock V30 charger with the phone at 5% it gives me a ETA of 1 hour 46 minutes. That seems awfully long time for quick charge 3.0 on a battery that is only 3300mah. It should be about 20-25 minutes LESS than that I think. According to LG it should be faster from their graphic at the release show of the V30. See attachment.
Although its possible a future software update could fix this though. So lets hope. I also might reach out to LG and ask them about this.

Does the quick change icon appears? Because that's the time that I see on my G6 with a normal 1.8A...

The little lightning bolt with a circle around it? Yes.
It also says "fast charging" in the notification instead of just normal "charging" when I plug in a regular charger.

When you or anyone elses plugs your V30 in at 5-10% battery. Then how long does it say until full?

Don't have a V30 right no, i've just compared the speed with the one seen on my G6, a 5-10% i have 1:50 for full charge without QC, for V30 you'll have to wait someone else...
quick charge feature is available only with original charger or by using power bank too ?
The Galaxy S7 adapter charges only at 9V/1.67A, for 15W of power.
The LG should come with a 9V/1.8A, for about 16W of power. Also, it may only quick charge with the screen off. It will drop to 5-10W with the screen on.
ummm...you should always check the voltage, not only the amps... (voltage multiplied by current equals power).
the best way to check is by using one of those USB thingies which measure V and A.
I'm pretty sure that v30 comes with qc 3.0 charger, so it definitely is a fast charger for that 3300mAh battery.
If I am not mistaken, the supplied charger is Quick Charge 3.0 compliant. But LG limited the charging to just 9V/1.8A, for total power of 16W.
The estimate on my v30+ at 7% battery is 1 hour and 43 min. In 15 min it charged 11% only.
Definitely slower than the galaxy note 4 I had previously.
The charger mine came with is 3amp and takes 45 min to fully charge

Ok I'm not saying you're bullshittin', but 3A gives 3Ah per 1h, or 3000mAh in one hour and since the V30 has 3300mAh battery, it must take over an hour to fully charge (even if it charges max speed constantly 0-100%), so yeah you're bullshittin'.

Yes! Very good point! What I have found is that it does charge pretty fast with the stock charger when you are NOT using the phone at all. Charges around 45% in 30 minutes from my testing. So pretty good!
However when I'm using my phone it takes about double the length of time. About an hour to get the same 45%. So I did a test to see what the heck was going on.
First I bought an Anker quick charge 3.0 18W adapter. So it is rated 2 watts higher than the stock LG charger. The Anker charger has output ratings of
3.6V-6.5V / 3A, 6.5V-9V / 2A, 9V-12V / 1.5A
I also bought a nice braided JSAUX cable rated up to 3Amps to make sure I am also using a cable that does not restrict the charge flow.
My results are about the same with that charger and cable despite it being rated 2 watts higher than stock LG charger. About 45% in 30 minutes when not using the phone and about 45% in 60 minutes when actively using the phone.
I also used an app to measure the charging current when not using the phone and when using the phone, and you are right. LG is for some reason limiting the Amps to only about 1.2A and 5V when using the phone, but then about 2.4A and 5V when not using the phone. I never saw the voltage go higher than about 5.1V. Assuming the app was accurately measuring the charge.
So I guess LG limits the charge when the phone is in use to keep the battery and phone from over heating while processor and display is working more? If so, it's obvious to me that they limit the charge while the phone is in use a good bit more than my 6P or S7 edge did. Hopefully with the upcoming Oreo update the charging rate is increased a little while the phone is in use.
When I had the phone, I measured with a USB meter. I was using a charger that's similar to your Anker, up to 18W.
With the phone or screen off, it charges at 9V/1.8A.
With the screen on, it charges at 5V/2A for 10W. But depending on what you're using the phone, eg. Watching videos or playing games, and your screen brightness, the effective charge is likely lower than 10W.
Since then, I've always developed the habit of not using my phone while charging.
Hi all,
I got OnePlus wall Fast Charge Power Adapter from ebay, and i test it with factory cable, i found its higher then the official one
the official one its between 1730 -1800
and the after market from ebay Ebay its between 2700 -2900 my question is the higher amp will hurt the battery life ?
regards
How are you measuring this? Ive found my One plus phones will not charge rapidly with my current measuring device plugged between them and the phone.
Next every single device I have, the battery lasts longer when I slow charge them. (More time on each charge) I charge my devices generally between 0.3-0.5 amps.

The charger uses 5V 4Amps. You should charge around 3000mAh below 75% after they it slows down.
