For cryin' out loud, I'm tired of watching my battery drain while plugged into the supplied USB charger. It's ridiculous. I've never owned a portable device that discharged under normal use when plugged into its supplied AC adapter. If I want to spend 15 hours a day playing Angry Birds, it should be possible when I have a power source which is virtually unlimited. Twice, I've started the day with a full battery, had the device plugged in to the supplied 2 amp charger all day, and had <10% left on the battery when I went to bed. (No, I don't actually play Angry Birds for more than a few minutes at a time but I do use the device a lot.)

I don't have that problem. You do know that your device will wait till it drops some percentage before it starts charging again. It won't keep it at 100% the whole time... Is meant to conserve your battery life

Let's pretend I've got just a little experience with portable devices. The standard is to float between 95 and 100% charge and just call it "charged" once it's bounced off 100% the first time.
Here's a test you can do that requires no time on your part. Set it up to play a long movie while it's plugged in. Look at the charge level after it's been going for a couple of hours. And you don't have to take my word for it. I'm hardly the only person complaining that the supplied charger is not capable of keeping up with the device's power requirements.
If you are seeing power drop during normal use while plugged in I'd talk to Google. You may have a defective unit. Mine doesn't do that and I regularly see 20+ hour days with normal use unplugged and usually with some video, browsing, games etc.
Take note off when you see the drop, how much you lose over a given amount off time and call Google and see if this is expected. I'm sure they will help. They have been very responsive when I've called.

I will watch like 1 hour of Streaming Vid's and loose like 4-5% while plugged in.
100% brightness causes my device to use more power then what's being supplied from the wall charger, and a few other people have confirmed similar incidents as well.
Max your brightness, and then go play a 3D game, while being plugged into the wall charger, and watch the percentage drop still
My tablet lasts a few days at least before needing a charge. I plug it in over night and it charges to full. I couldn't be more happier with it considering it is not self-sufficient.
Mine drops a few % per hour in use with the stock charger connected. Brightness at 50%, WiFi on, BT off. I'm not going to whine about it, but its the only thing that's not great with this tab.

Why do everyone seems to think that the POGO-charger would be able to charge the Nexus faster?
I've read on an Ipad forum that about 10-15 hours charging are normal (the Ipad 4 has a 42,5Wh battery), and their chargers give as much Watt as our Nexus chargers.
One thing is clear, you can't increase the voltage. That would kill your Nexus right away.
My Samsung charger I recieved with my Nexus 10 says 5V out and 2A.
5*2= 10W.
Isn't that the same rates that other tabs have, even if they got special chargers?
So, the only thing the POGO-charger could raise, is the amount of current.
Even if you had a 10A charger, if the Nexus cant use more than 2A, it wouldn't get anymore amps than 2.
If the kernel on the Nexus doesn't support any higher charger rates, then you cant change anything.
There is a reason why the manufacturers have set 5V as standard - to make it work together with USB.
Battery Specs: Samsung Li-Ion 3.75V 22.75Wh 9000 mah.
So, it's easy. If you had a 1W charger, it would take 22,75 hours to get a fully charged battery.
In theory, it should take 2,75 hours to fully charge the Nexus 10 battery, but we don't turn it off, we use it while charging, it uses background sync and I dont know what the efficiency rating is on the charger or the Nexus.
You know you could feel some heat on the back of the Nexus 10 after some usage?
That's some of the battery's energy that spoils into heat, meaning that there are power losses.
It's normal though, we don't have anything yet on earth that could convert 100% energy from one form to another.
You could compare it to a car, you need a cooler-system to remove the excessive heat from the engine.
Even if your Nexus is far more efficient.

Please do not speculate about how much current can go through the pogo connection. Speculation is worthless and helps nobody. The fact that the included charger only puts out 2 amps probably has to do with limitations of the USB connection. But I'm speculating. See how pointless that is? The fact that one connection is limited to 2 amps doesn't mean all power connections are limited to 2 amps.
And where did I say anything about increasing the voltage? I'm not an idiot and didn't suggest such a stupid thing.
As for temperature, that can easily be monitored during charging and the current can be reduced if it gets too high. You are aware that there is a temperature sensor for the battery, right?
None of which has a darn thing to do with my opinion that it's unacceptable to produce a device that uses more power than it can get from its AC adapter. If there really is no way to run the Nexus 10 at full tilt without supplementing the AC adapter with battery power, Samsung should have addressed that problem before going into production with this unit. This isn't a $150 entry level device. It's the Android flagship.

Please, you started speculating about a high-current POGO-charger that doesn't exist.
Sure, you didn't mention the voltage, but I ve seen comments about it before, so I just wanted to make it clear.
And I didn't say the temperature was a problem either, just that it lowers the efficiency of the charger and the device.
Samsung maybe didn't know there was a charging problem.
We've seen examples before that manufacturers don't test their products enough.
(ASUS Transformer with encased aluminum body, anyone?)
And I know, this is supposed to be a flagship, but what everyone forgets is that it's much cheaper than other brands.
I was looking forward to buy a ASUS TF700 with keyboard at almost twice the price as the Nexus 10 before I read about the Nexus.
Even if it doesn't justify the charging problem, you could try to adapt to the circumstances until there's a solution.
When I'm low on battery, I let the device charge and do something else for a change.

I have a nexus 10, nexus7, and a Tf700. I am noticing slightly faster charging on the n10 using the Tf700 ac adapter. The same is true when trying to charge my tf700. The stock samsung n10 ac adapter charges it slower than the asus transformer adapter. The same is true with my nexus 7 adapter. Ive used the n7 adapter to charge my tf700 and it was not as quick a charge. Meanwhile all 3 units are rated for 5v 2amp.

Could be possible the N10 charger isn't actually putting out 2A? Might need a multimeter or something to verify for sure though...
I am currently out of town so keep in mind I didn't have a chance to dig too deep but I've given the kernel a quick look through.
There is no such thing as the "high current pogo charger." The pogo pins accept 2A max and appears to be ~5V. The USB connector has the same limits.
I also took a look at the current at the battery to make sure the charger was being detected correctly. My 1A Samsung non-Nexus 10 charger seems to supply ~900ma to the battery which is as much as you should expect out of a 1A charger. My Nexus 10 charger supplies ~1600ma to the battery. This number seems slightly low but at least indicates the charger is detected correctly.
*If* the pogo charger does indeed charge faster, it will likely be because the pogo charger is able to supply some current that is asymptotically closer to 2A. In other words, it will not charger much faster than the USB charger.
On the other hand, the pogo charger will still be nice to have as it will allow simultaneous usage of USB OTG and charging.
Like I said before, I was unable to dig very deep because I'm out of town and browsing sysfs and kernel source on a tablet isn't the best experience. So, the info I found might not be 100% correct.

There are many indicators throughout the kernel but for brevity I'll post what I think is the most concise.
https://github.com/CyanogenMod/andr...ng/arch/arm/mach-exynos/board-manta-battery.c
Line 773-776
Sets the current to 500ma if USB is detected on the pogo or 2A if AC is detected.
Well if you're reading 1600ma using the standard ac adapter that comes with the N10 and possibly closer to 2000ma (say 1900ma) using the pogo, then that is 1/5 faster charging. In terms of time that is quite a saving.
Of course, that is all speculation
USB current limits
I thought I'd post this as information I found while doing a spot of light reading
The current specification of a USB 2.0 port can be a maximum of 1.8A. Within Constraints.
"Battery Charging Specification 1.1: Released in March 2007.
A usb charging port places a termination resistance between D+ and D- to allow the maximum 1.8A", meaning that at this current, there can be no data transmission.
This appears to be increased for USB 3.0 standard.
"Battery Charging Specification 1.2: Released in December 2010.
Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A."
citations come from documents here:
http://www.usb.org/developers/devclass_docs
As POGO pins do not have to follow any specification the only limit is the current the board & charging circuit can handle.
Look at the specs on the wall plug in unit. It's not a charger it's a 5V power supply and the charger is inside the N10. However the charger is setup determines the charging rate. Like mentioned above, it may not matter if you "could" use a 10A at 5V power supply.

Charges faster in phone...while using!
If battery is around 40% it being be charged overnight.
Anyone else experience this?
could be the amp? maybe below 1 amp? Samsung charger has 2amps om it. check your charger and look for the amp. btw. the lower the amp the better for your battery..
Buy an OEM charger. The Samsung one is $50 from Samsung website but you can get the Asus charger from Google play store for $25. Both are two ampbi believe. Or you can get the 1a for $25 from samsung. Getting OEM directly from an OEM or authorized reseller or a storefront lime Google is key. Getting cheap chargers is gonna bite you in the ass one day or think about it like this. Why keep wasting time buying cheap chargers again and again when you can put up proper money and get quality in one go and have peace of mind for a few years. I even stopped buying chargers from amazon because they're just cheap knockoffs too. Phi hong makes good chargers and power supplies but they are harder to source. Phi hong came with my nexus one andy galaxy nexus OEM Home dock.
Anyways, aside from that part of the reason for slow charging is you probably have an unsafe charger that is not rated what it really is and is made of poor materials. Getting a quality 1a or higher, preferably 2a in this case and your gnote2 should charge @ 1.8a. In other words, you can charge from zero to full in ~2-2.5 hours. Or from partially full to 100% in less than 2 easily.

Unless I am mistaken, OP is referring to battery chargers, not usb chargers. That's how I charge mine, too. I have spare batteries, and they all get charged directly. When my battery is low, I just swap. I hate having my phone attached to a cord, even at night.
Yes, all the battery chargers I've had for every device (including this one) have been lower amp than the usb chargers supplied with the phone. It is especially slow for this huge battery for the Note 2. While it bothers me in concept, it's never actually been an issue for me, so I haven't done anything about it. I don't know if higher amp battery chargers are available, but I don't feel like spending extra money on one.
As far as battery health goes, charging at a lower amperage certainly isn't hurting the battery. If anything, it's actually better for it.
Yes...charging just the battery with wall charger.
@ 40% it will not be charged at 6am when I wake!!!
Are there better wall chargers?
Why do you hate having your phone attached to a Cord overnight. I heard that's fine and do it every night.!

Not for the phone, for me. It just bothers me having a wireless device locked to a wall. There's no reason for it. And I frequently get up in the night for various reasons (kids, work, insomnia, etc), and it bugs me unplugging in the middle of a charge cycle.
Incidentally, a non-removable battery was a deal breaker, and one of the reasons I didn't get a Nexus 4. I got used to never plugging in my last phone, and I don't want to go back. It was torture the first week or two with the N2 before my spare batteries arrived.
The charger should have its output printed on it, I've had a look at the pics on ebay and the first two I found that I could read were 500mA and 350mA, the original charger is 2A or 2000mA. Samsung make there own battery charger http://www.samsung.com/au/consumer/...es/EB-H1J9VNEGSTD?subsubtype=other-multimedia the output is 1.7A so much closer to the original usb charger.
I'd be worried about my back cover getting loose doing what you do. I had three batteries for my old phone, but I did not swap them on a daily basis, just when travelling or away from power for an extended time. I've ordered some wireless chargers so I can have one by my bed and another downstairs. I know they only output 500mA too, but for an overnight charge thats fine for me. I dont think there is any issue with interrupting the charge cycle, the two main enemies of lithium batteries are heat and being totally/almost discharged on a regular basis. Its best to keep them topped up.

It looks like the OEM battery charger is available on ebay for around $15. That's good to know in case mine ever crap out on me. These cheapies that I get tend to.
As far as the back cover getting loose, after 3 months, it is a little bit looser than when it was new. 1.5 years with my G2x didn't loosen it at all, but the build quality on that thing was fantastic. I keep this in a case anyway, so it being a little looser goes unnoticed. If it gets bad, back cover replacements are cheap.
If one of the devs can make the kernel capable of fastcharge, it would not take but half the time to charge. Yank who is working with Faux on his kernel, helped make the kernel fast charge capable.

But what is the point of having it charge fast, when all it is is going to drain faster?
I charge mine overnight with a charger rated at 750mah I believe and it last me a whole day. As oppose to using a 2.1 am charger I have, where the battery percentage would start dropping by the first hour.
Correct me if I am wrong here, but this is what I've notice with my last few phones.
The Perseus kernel with stweaks has the ability to change the charging parameters.
With it overclocked/undervolted I am getting better life than I did on stock.
Not for sure what you mean as it depleting the charge faster on a higher amperage charger. Kind of sounds like you may have had failing batteries, etc.
There seem to be a few misunderstandings here regarding batteries and chargers.
1) The charge rate, when the battery is in the phone, is controlled BY the phone. The charger itself just supplies regulated power to the phone. How much current is put into the battery at any given time is up to the phone, which is why kernels can do things like fast charge, it's controlled by the kernel. Now, the reason the battery charges faster when using the stock charger vs. something lower current or a computer is simple. The phone can detect what it's connected to within some limitations. It sounds like our phone can also sense the incoming voltage levels and back off if the supply becomes unstable.
2) Using the stock 2A charger is "harder" on the battery than a lower current charger. Not true, at least not within any margin of error you will be able to detect without specialized equipment. Lipo batteries are generally built to charge/discharge at 1C. C in this case stands for capacity. So our 3100mah batteries can charge at 3.1Amp and be within safety margin. So the 2Amp charger the phone comes with is perfectly fine for the battery. Without seeing a datasheet for the battery from Samsung, that's a good guess. And again, the phone controls the charge current based on a number of parameters. You could connect the phone to a 5V supply capable of 100Amp and it will still only use what it needs.
3) The percentage readout on the phone screen is a GUESS. Don't pay it too much attention. For this same reason, evaluating 3rd party batteries based on phone runtime etc is not useful. To validate the battery capacity with any accuracy requires a test setup discharging the battery through a known load and measuring how long it takes to get to a cutoff voltage. I've done some of these tests myself on stock and 3rd party batteries. In general, the OEM batteries are always at or above spec, the 3rd party battery manufacturers lie. Often by upward of 20%. Even the high $ batteries. Keep that in mind when shopping if you want extras or extended batteries.
4) Interrupting the charge cycle is bad. Nope. It's fine. On this same line of thought, full cycles ARE bad. Don't do it. Don't think too much about it either though. Just plug it in when convenient. Or set it on the wireless charger if you've installed one. Generally speaking, they actually don't like to be charged to 100% either. Keeping it at 20%-80% is actually best for the longevity of the battery cell itself. In practice, you will probably have a new phone before any of this is actually noticeable.
The OP sounds like they are talking about a stand-alone charger, where the battery is not in the phone. Those will vary wildly in quality and capability, particularly from ebay. They are probably cheap POS devices. Not that that's really a bad thing, just know about it. It's probably a very low charge rate device, perhaps even down to 100ma or so. That would take forever to charge our larger batteries. As for if there is a better one, probably. If Samsung makes one, it will probably charge faster than the phone with the provided charger plug as there would be no load from the phone using power. Of course, it will cost a lot more as well. Look for devices that at least claim they will charge at 2Amp or so. In practice, they will probably be a lot lower, but your chances are improved. Not many people will break out an ammeter and check, after all.

Perseus kernal has fast charging settings.
What ttabbal wrote is mostly correct. But the problem lies within some input voltage protection logic tied to the charger chip of the phone which is extremely (and too much so) sensitive.

Can people stop calling it fast-charge, it's an idiotic term which technically means nothing. While most kernels have some sort of charging speed configuration options, they're all useless in regard to this problem as the current in the end is decided by a different logic. You'll have to disable unstable power detection and that's the only way to make it work and fix the problem, unless you go hunting down high quality cables and chargers.
Personally I also encountered the problem as my stock S3 charger, as many others here have reported, has deteriorated and it would only charge at an effective 300mA. I disabled unstable power detection and now it charges at the full given current limits, without any issues.

You have to make sure it's "2a" charger capacity. It happened to me once. Go to monoprice.com and search for a universal 2a charger... pretty cheap
So yesterday I bought a 2.0 charger off of amazon with the choe brand name. According to the ad it works with nearly every android phone, including the HTC one m8. For the past year I have been using a charger from my last phone which was a crappy flip phone and thought nothing of it, but I am wondering does this charger truly work?? According to app "Ampere" it is much slower. Also, I've read reports about phones heating up and that's what mine did last night, is that normal? How long should it take for me to full charge my HTC one m8?
It will heat up, that is normal. It'll use most of its 2.4A between 20 and 70% and then slow down. Your total charge time shouldn't take more than 1 hour, and make sure you're using the supplied cable.
Thanks for the response! So if it doesn't charge 1 to 100 in 1 hour than is something wrong? Also will a charger like this have any effect on how long my battery lasts? My last charger for whatever reason was for my last flip phone believe it or not, I never bought a new one.

no I wouldn't say that.
my 2.0 QC will get it done in about 1-2 hours compared to the 3-5 or so it took with stock charger.
0-100% will take more than an hour. I've timed mine a few times from 0-100%, not using the phone at all and in airplane mode waking it up every 5 minutes to check percentage, volts, and charge rate using Gsam batt monitor.
Comparing the two chargers (OEM HTC QC 2.0, and original HTC charger- which I believe is QC 1.0) the QC 2.0 is definitely faster. Even though there is nothing on the phone telling you it is using the higher wattage charging mode, it is. So, 0 to 100% using HTC's QC2, usually takes around 1:20 minutes if I remember right. As in the other post, it starts out rather slow to around 20%, then kicks in to high gear until around 80%, then slows back down all the way to 100% so as to not overcharge the battery and harm it. It really is amazing the speed that it charges at. It does get rather warm, which is normal, but shouldn't hurt the phone.
Now, completely draining and recharging these batteries frequently is not good for them and will decrease the useful life sooner. Keeping it somewhere around 80 % is ideal but realistically not practical and the manufacturers know that. That's why they build in overcharge circuitry protection so leaving the charger on all the time "shouldn't" harm the battery. Draining it down to zero and doing a full recharge cycle on it frequently WILL decrease the lifespan. The batterie's useful life is basically determined by a finite number of charge cycles.
There's tons of info on charging and batteries out there if you are looking for more reading too.
Anyone heard of the brand Auzen? It's popping up alot on aliexpress and around asian market. Not too much reviews yet on that brand.
don't play with quick chargers .I bloated my m8 batt once trying it .it charge at 2.4a .our device max is 1.5a.
If you insist using it then don't full charge with it n monitor closely .
That's impressive, I use a QC2.0 car charger, I use a variety of wall chargers that run from 1.0A to 2.3A at 5V.
So far, my battery is still very happy.
Sounds like you got a cheap knock off charger or your battery/charging circuitry was damaged/faulty and/or your ROM/firmware weren't proper, for that kind of damage to occur.
I don't think Ampere works. I once did a test (last month) and had 6 different USB cables and I wanted to see which was the best, every time I used one I got a different reading, from 200 up to 1600. Even using my Anker Quick Charge 2.0 I only got 400 so it stated.
I have been using Aukey QuickCharge 2.0 and gives pretty decent charge times.
I have a QUICK Changer 2.0. works great.. have some tips...
You know there is some colors on cable conectors ends you have to choose the right one..
- If the cable is not a quality one can result to slow charging.
Black ----- 1.0. most in stock phones
White------ 2.0. the right for fast charging...
The time on reaching 100% on battery,well Quickly charger 2.0 will reach 80% on your battery fast and it will change the next 20% slower...
There is some app in playstore can help can see the amperage live in mA..
Connect your charger to get the battery charging current or disconnect it and get the negative discharging current... and you can see your battery charging current mA is constantly changing because even on charging phone still using current (negative discharging current) and this is always changing.
On my case I see higher mA reading only under really low battery...
I have a problem with my m8 and aukey 2.0 quick charger....
After firmware update to 6.12.xxx.xxx mm , the app ampere tell me max 1600ma before update its tell 2000ma .. Its a bug or a feature of the new firmware base...??? I have cyanogenmod 13
Im using the same aukey 2.0 quick charger. Works perfect.
M8 is 1.5a max .if you use 2.0a logically you're overcharging it. Just wait for it to get bloat n replace the whole bat. worth it ?
Hi, i just wanted to say something. After many bad chargers i bought, i found the Nillkin chargers (2Amps)and Nillkin cables (2.1Amp) the best and best quality. I am always testing with good Usb voltage tester and it can charge up to 1.5 amps max on M8 and on LG G3 1.8 Amps. As long as the charger is 5.0V, amps can variate and it doesnt hurt your battery, it just charges slower or faster. In my case its charging 1% per minute on both phones. It doesn't matter if the cable is black, white, green... cables must be thick, around 18AWG that support high ampers which mean faster charging. thin cables are sh!#. And for car i also found the Scosche dual charger great for every device with Nillkin 30cm cables and Kenu airframe holder.
You can use 2.4A chargers on M8 without problem as it will only receive 1.5amps.
GL
I'm using Anker PowerPort 1+. It's very good and you can use for iPhone iPad & almost Android devices.
I bought it here: http://www.amazon.com/Anker-Charger-PowerPort-Samsung-Wireless/dp/B014F3D8FQ

That logic is incorrect. The phone will only draw as many amps as its rated for (1.5 amps) regardless of what the charger is rated to supply. Think of the charger amp rating as the "maximum it can supply" instead of "what it will always supply".

Ampere shows max charge rate for me at 2000ma. Where do you get the idea it will overcharge?
Which charger to use? (no quickcharge)
I bought a Samsung charger for my upcoming Nexus 6, i don't want to use the quick charger that comes with the phone. I am starting to suspect that this one is also a quick charger, can anyone look at the attached pictures and tell me? Also if it isn't a quick charger i would like to use it for the long run so my second question is would my battery be affected because of what says on the back of the box that i highlighted? In the highlight are also the specs of the charger, can someone clear this up for me?
EDIT: I cannot post pictures on the forum just yet, so here are the specs
10W Samsung travel adapter, Input 100-240VAC 50-60Hz, Output 5.0VDC 2A
Use only with compatible Samsung devices

I want to use the phone for a couple of years and don't want to shorten the battery life and also have the risk of inflating battery and everything that comes with it. What kind of charger should i buy to charge it in some "normal" time? The salesman in Samsung store told me this one charges Note 4, Galaxy S5 - which is why i bought it - the S5 doesn't have the quickcharge tech so i instantly thought it was an ordinary charger. On the other hand, my Galaxy Nexus official charger is rated for 1.0 A which surely isn't strong enough to charge the 6 properly so i am confused with what kind of a charger and with what ratings should i get? Thank you in advance.

2amps isn't going to shorten the life below 2 years. Higher amps only shorten life if they are above battery tolerances, which 2 amps is not.
Anyway, you'll want a 1 or 1.2 amp charger for slow charging

If I were you, I would use the charger that comes with the Nexus 6. Which is tested by Motorola to work properly. I've had my Nexus 6 since December 2014 and no problems. I charge through my laptop will at work though.

He wants slow charging. So charging through laptop / pc will be fine.
Charge cspacity of usb ports is 500 mA (900 mA for USB 3.0), that's good for slow charging.
Also 1-dollar charger from eBay will be fine.

Nope. So the only thing that will change is his phone will take longer to charge.
That said for me, turbo charge stopped working and I'm very annoyed.
Google have first sent me a new charger which still hasn't arrived. Though I think the issue is the phone. But I wanted to avoid a refurb as long as possible. Can't live without turbo charge now.
I have this charger, http://www.walmart.com/ip/Belkin-F8J031TT04-BLK-Micro-Wall-car-Chrg-Kit-2.1a-10w-W-4ft/40457559, but i got just the charger for $20. It most definitely doesnt turbo charge, it takes atleast 2 hours, so id say its a "normal" charge for this phone and i think its better than the turbo charger, because it doesnt get hot and its still decently fast

The turbo output is only supplied on turbo enabled devices. So there is something wrong with switching to turbo modes 9 V and/or 12 V
I am curious what is the cause of this issue.
Did you try an 'charge app' like Ultra Fast Charger.?

There are some apps in the play store claiming to boost the battery charge.
When wireless charging is also slow, than it could be indeed the battery.
Maybe a complete discharging ?
BTW
Turbo mode is only active when the battery is less than 75% charged.

You should use a 5 Volt 2 Amp charger, those chargers are the one's that most phones use. Most new phones are using Qualcomm's Quick Charge 2.0, which you should use but if you are not comftorable then the 5 Volt 2 Amp will work good.
Errr, QuickCharge will in fact degrade a battery faster, it's still used because most phones only have a 2 year lifespan.
A non QuickCharger will also make it run less hot while charging and also be less likely to cause cell expansion. Not sure why there's so many people denying this.
EDIT:
Including some sources:
http://www.sciencedaily.com/releases/2015/04/150414094117.htm
Please don't tell him that it won't degrade his battery when it definitely will. It's basic chemistry.
To OP:
Any regular non Quick USB charger of reputable make will do fine. I use an older HTC charger. Don't get a super cheap offbrand one as it probably has fluctuating voltage which will also damage your battery.

Actually you've misread (or not read fully). No one disputes the science. That article isn't accurate. All it says is "too quickly" and if you read what I have said, is that the turbo charger is within acceptable tolerances. I.E. It is not "too quickly"

I think you're not understanding the basic chemistry. More heat = more degradation of the Li-ion battery, regardless of tolerances. A lower power charge will always degrade the battery slower. This isn't about tolerances.
So few days ago got the phone , but always charged it through USB port. Now finally tried turbo charger and it definitely isn't "turbo". I know most of those Turbo claims what I saw were just selling strategy , but I'm pretty sure I'm not even getting 1% - 1 minute. Latest Marshmallow OTA.
So , on a relatively new battery , how fast does your phones charge ? You can write with phone turned off and on..
Also looking at the charger it says for output :
Standard output :5V =1.6A
Turbo output :9v=1.6A
Turbo2 output :12v = 1.2A
This deosn't make any sense to me, while raising volts may solve some power losses through cable , amps are what charges your phone faster or slower , and 1.6A , isn't really a big deal not to mention 1.2A. Reading somewhere that quick charge 2,0 supports up to 3amps draw..
I have One Plus one and it's original charger is 2.1A (quick charge 1.0 ) , with custom kernel bumped charging rate all the way up and good cable I'm seeing about 2Amps of charging in real life , or little more than 1% per minute . I was expecting motorola to charge faster or at least even , even though they are 3100 vs 3900mAh batteries.. Not to mention I can easily mod OnePlus One and get same SOT and battery overall as motorola's, while on motorola I'm stuck with stupid locked bootloader . Original idea was to sell OnePlus One because of Motorola, but I don't know now anymore..
The volts and amps listed on an electrical device are typically its max or rated output, NOT what it "always" delivers. That being said, most power supplies will deliver their rated voltage most of the time, but the current is determined by the charged device (through it's effective resistance)... so as long as you run below the rated current, you'd be fine.
Secondly, from what I'm reading, the OPO doesn't have quick-charge technology (ref: https://www.reddit.com/r/oneplus/co...lcomm_quickcharge_20/?st=ix64k1gy&sh=6d7492c9 ) so I'm not sure what you're talking about there. Again, the charger may say 2.1A, but that doesn't mean it's actually delivering that much all the time. I have a relatively old Kindle Fire with a 2.1A charger, but I know it doesn't charge very fast even with that device.
If you want to talk about Volts and Amps, you need to use actual volt/amp meters to see what you're getting.. Note, there is an app for Android (called Ampere) that claims to report amp-rates, but it also has a caveat saying that the current should not be taken as completely accurate, for various reasons.
Lastly, note that QC doesn't actually run when you are at higher charge levels... I think it's above 80% or something? After that level, it returns to "standard charging" mode for this "top-off" phase of the battery charge cycle. So, if you're seeing slow charge rates there, it's to be expected.
The Turbo has a relatively massive battery. Mine takes...somewhere upwards of 3ish hours on turbo charging to replenish.
1 hour 15 minutes
that's what it takes to go from 0 to 100% using Turbo Charger 2.0
Thank you all for answering, this is exactly why I started this thread. Already see here some interesting results!

Thanks! Actually, OnePlus ONE DOES have quick charge 1.0 which is 5v up to 2.1A. Snapdragon 801 supports quick charge 2.0 but OPO didn't implement it with phone. There are billions of topic on this at OPO forum and a lot of people done tests including myself. The problem with OPO is it's very sensitive on cable so it works best with OEM cable and it somehow recognizes it. There is app called OPO charging current so I monitored with it and synapse . Kernel setup hardware to be able to recive very max 2100mA no mather which cable. Stock ONEplus charger. Some cheap cables gave me from 300 - 600 mA max with screen on . I found at home some cable that looked cheap but said charge only, tried and it charged around 1600mA with screen on and around 1800 screen off. Later got Anker 21 AWG and results were even better , aroun 1800-1900mA screen on and close to maximum 2000mA screen off. Phone was charging 1% in less than a minute. Thought turbo can charge at same rate. After all , it's "boosted" lol.
I know it doesn't do quick charge after around 75% , I tried at 30%. Given all that , 1600mA which is maximum I see on the Motorola's charger is not something special if we disregard Voltage..

According to your guess-timate and max rated power I see on the charger, that seems about right and realistic guess BUT there also isn't anything TURBO about it. I'ts the average charging speed of every device today (1.5A) which doesn't have any kind of quick charge option. Even quick charge 1.0 is faster with 2.1A at 5v . Thats why I opened this topic, I'm confused.
Only voltage is higher on turbo charger than let's say my OPO charger but amps are lower and voltage doesn't have that much of an impact on charging speed, amps do!
When I have my Turbo in my truck at night, and running about a dozen things at once, in addition to all the background stuff, NO 'regular' charger can keep up with the power demand, and the battery undergoes a insanely slow discharge. By itself, the battery lasts 3 or 4 hours, tops. With the turbocharger, the battery charges at a modest rate, maybe 10% per 30 minutes...while under high demand.

I encourage others to post their charging times so we can compare!

Since no other turbo users jumped in...
At the time of starting the topic I have disabled some Verizon's bloatware (completely stock, locked turbo). After reflashing completely stock FW , and with untouched software, droid really did charged turbo fast. More than 1% per minute and around 0-60% for 30min just as advertised for quick charge 2.0 . So if anyone was wondering, that should be benchmark.
On the other hand, phone is almost impossible to charge with any other type of "normal" charger..
My Turbo, running stock MM/root/Xposed with a large load of apps, will charge 20-30% per hour on a normal 1A charger, while lying on the desk with the screen off. It charges at a similar rate via Qi wireless charging. This is plenty for daily overnight charging. My usage habits are such that I usually have 20-40% battery left when I get home from work in the evening.
In a different usage case, when I play Ingress (a real battery eater, screen on + 3D animated graphics + GPS + data) the Qi charger in my car holds discharge to about 5-10% per hour.
I've never had a turbo charger to compare, but I've never found the normal charger or Qi charger to be significantly lacking.

Right, I've also used "normal" charger before. Now, I have all QuickCharge plug chargers -- but I still use Qi wireless charging every day, as does my wife.
I also plug in via USB port on my computer and it charges fine.
okay the way the turbo charging works is that it's like a tier system at very very low charge percentages it works the fastest and slows off after about 60 or 70 percent it just charges like a regular charger all the magic happens at the lower charges. another thing is that unless the cable you are using is total garbage it won't matter at all. it is all the phone and the ac adapter that do the work any variations in the cable will be negligible. I am monitoring my battery through the custom kernel (bhb27 and its app) and it says right now at 81% charge on a turbo charging that I am getting +1172.x mA if my battery was lower this value would be much much higher
lastly I recommend only using the turbo charger when you really need power quickly. if you are just plugging in your phone for the night it makes no sense and will actually be bad for your battery health. the faster it charges the more it heats up and heat is not good for the battery health when I plug my phone in at night I use a .5 amp charger and my phone says that it will need like 8 or 9 hours to charge (this may be exsessive but the quick chargers heat up my phone a lot I also use a 1 and 2 amp charger nearby
