Last nite, I played dead trigger until battery warning indicated 4%.
But I still keep playing and suddenly the screen went black.
I think the battery is totally dried out at that time. So I used the following
charger but failed to charge even after 10min. Here's the charger:
1. 3rd party 5V 3A charger,liteon brand.
2. old nokia 0.5A charger.
3. original samsung note2 charger.
all those 3 charger works normall on my n10 before last nite.
and suddenly i think maybe i can try out the original charger of n10.
And it works!
So i wonder if samsung or google put special charger on the adapter?
Before we know anything furthur.pls put ur n10 charger in safe place.
I think most tablet chargers output a voltage of 12v. That might of kicked your battery back to life.

I've confirm the voltage of my n10 adapter. Which printed "5V 2A".
It probably just needed a certain amount of minimum battery voltage to function and show charging. I doubt if the OEM power supply is special in any way. The charging circuit is really inside the N10.

when i plug in the non-n10 charger, even after 10min,n10 is not able to boot. Only flaahing the battery charging symbol for 1 sec.
when i plug in the original charger, n10 can be boot instantly.
thats why i think it is very weird about the original charger. but other chargers still works well when n10 battery is NOT completely dried out.

Yeah, that is very strange indeed. It does draw in the 1800mA range from the battery during boot up. Are you using the same micro-USB cord all the time? It was reported that there are big differences in charging rate with different brands of cords.
This was covered in another thread recently.
Basicially the Samsung chargers have 2 pins shorted together to get full charging power of around 1.5A with the n10. Using other chargers will get you around 500ma output.
My guess is if you left your tablet on the "other" chargers overnight it would come on just fine. They simply don't output enough juice to power the tablet when the battery is that low.

Had you left the other chargers on long enough, the tablet would have booted fine. I've run into this. I have an old(er) Samsung Tab 2 10.1 charger I use with my N10 (now along with a Pogo cable) and my N10 charges rapidly. That, coupled with the two wires shorted out in Samy's setup for the larger amp's.....also, in my job, I work with other chargers all the time and use them all the time across multi platforms, to include my N10, and it charges fine (albeit much more slowly).

My charger(PS) for my Dell Streak 7 works just fine with the N10. This all makes sense except for the fact that the poster stated using a: 3rd party 5V 3A charger,liteon brand which didn't work.

Should still work fine. Voltage is the same and the device will only draw as much amperage as needed. May have something to do with the circuitry in the charger? It may have been bad. As long as you don't supply more volts you are OK. More amps is also OK. Not enough amps will lead to burning up the charger unless the device is smart enough to realize its on a low amp charger (like the n10) and kick down so as not to over draw (ie - over drawing from the USB port which is a .5amp (500mAmp) or 1amp (1000mAmp)...someone correct me on the number here please)
The whole reason manufacturers tell you not to use someone else's charger is so you don't plug in, say, a 12 volt charger into a 5 volt item. That would pop something. That or some cheap charger poorly built could allow "dirty" power through causing problems. Both issues voiding warranties
Not sure if it's been mentioned, but depending on the usage of the tablet, you might not be able to charge it quicker than the power usage. For me, if I'm playing a demanding game at 1.7Ghz and max brightness, neither USB or Pogo can charge the tablet, and battery still drops (slower, but still drops).

Never seen anything burn up because of low amperage., power or watts generate heat and power(watts)=voltage x current.
Did you ever see a PS(charger is inside the N10) with a USB port that supplies anything but 5V? I haven't.
Current (amps) does the charging.
No USB charger will provide anything more than 5.1 volts. If the charging block has a USB plug look at the rating. Amperage for smaller devices may be 1a or even less. Newer big smartphones have bigger batteries and need more current to charge. My old Thunderbolt charger is 1A, the charger Motorola provides for my Maxx HD is 1.5A, the Samsung charger for my Galaxy Tab 2 7.0 is a 2 amp charger, so is the charger for the iPad that some frickin' jerk ripped off from my house. The Xoom escaped that problem by having a separate charge plug, not using the USB system, it 12 volts at 1.5 amps. See the pattern? A tablet of any kind has an even bigger battery and needs even more current to charge. The reason the N10 may lose charge even when plugged in is that the charger can't deliver the current needed to run the device and charge the battery simultaneously.
As I see it, Samsung and Google need to supply a slightly higher amperage power block to compensate for the use/charge balance problem. Our solution would be to turn it off and charge the device every night or even leave it plugged in when not in use.
Another thing is the surface area for current transfer. The USB points are tiny, the POGO Pins, dedicated to charging would be able to handle more current because they have more surface area.
Any one who knows better may correct me, I just ordered an N10 today from Google so my information here is what I have read here and what I know from years in the electronics field..

You don't need more current to charge a bigger battery, it's all about how long it will take to charge to full.
Some have stated that they've seen a 3A battery drain with certain games. The 9Ah battery would last approx. 3 hours which exceeds the max rate of the charging circuit and the PS. Even on a fully charged battery at that rate doesn't last that long.
AFAIK for any tablet to be able to draw 2A from any 5V charger (that can supply the needed amperage) the data pins (middle two pins from the use cable) have to be at 2.5V. Otherwise even if the charger is with correct specifications 5V/2A the tablet might not charge at all, or charge at a lower rate.

I forget the actual brand/model of the actual charging chip but if you poke around in the N10 files you can find it but it's specs are list as 2.5A max but N10's code limits it to 2.1A. This isn't the PS wall wart commonly called the "charger".
The recommended charging current for any lithium ion or lithium polymer is 0.7C. What that actually means is a current 0.7 x max capacity in mAh. For most phones e.g. my Galaxy Note 2 with a capacity of 3100 mAh this means a current at about 1.7A.
The battery Nexus 10, on the other hand, could very well be charged at a whooping 6.3A current.
In USB Battery Charging Specification 1.2 the maximum current a USB port can supply for charging purposes can be as high as 5A.
With the Perseus kernel for Note 2 you can actually specify the max limit for how much current the phone will draw from any charger.
So in theory.. it should be possible to charge the Nexus 10 with a 5V 5-6,3A charger.. and that would probably be very quick!
For the record: I havn't seen many (any?) chargers with more that 2.3A

Sure the charging rate is way under what it should be but as they use larger and larger capacity cells the only solution is a removable cell to charge by other means.
Hey guys I just bought the Nexus 6 and been looking around here and didnt find anything on best ways of charging the phone. I know the phone comes with the quick charger, but I tried it and the phone got real hot and I am pretty sure its not good for the battery in the long run.
That being said I do not want my battery to start losing charges since it does not have a replaceable battery. I am just curious if anyone on here uses other methods of charging the phone or better yet if anything is proven to be safer to charge. Right now I am charging the phone with my previous Samsung s4 charger and seems to charge fine, but if its not good to do this I would like to know sooner than later.
The n6 is meant to charge fast and isn't the first phone to use fast charge technology so I think we are fine using the stock charger.There's no way a battery charging that fast isn't going to get hot.
Define "real hot."
It is normal for the phone to get quite warm when charging. It should never be hot to the touch though. In this context, by hot, I mean you're unable to hold the phone. If you're able to touch the back, and keep your fingers there for more than a few seconds, then the phone is warm, not hot. Anyone who has had a battery overheat can tell you that the difference is unmistakable.
Chargers will, by definition, heat the battery to some extent -- how much, depends on what kind of charger. The order (from warmest to coolest) is: QuickCharge 2.0 (Turbo Charger), qi wireless charging, QuickCharge 1.0 ("Traditional" 2A charger), Regular 1A charger, USB charger (500ma). However, the heat produced by ANY of these chargers is normal, and the battery was designed to handle it. The life may be lessened by the heat to a very small extent, but it should still last way longer than the 1 to 2 years you'll likely own your phone. Plus, technically, the battery IS replaceable. It's just not designed to be user-replaceable, but there are businesses that will replace them. Or... you can purchase an after-market warranty, most of which cover batteries.

I meant just warmer than normal use of the phone. I understand the phone gets hotter the faster you are charging, however I charge my phone every night so what is the point of the quick charging except when I am at work and my phones about to die?
I just feel that the phone will last longer by not quick charging it, but I could be wrong. What I really want to know is if anyone knows if its better for the phone if you just charge with the 1.0 and if so which charger should I use? Maybe another motorola one or would the samsung one work fine?

Technically, yes, it'd be better for your battery, but realistically, you'll never notice, since you'll probably get a new phone long before battery life becomes an issue.
However, to answer your question, any 1A charger designed for Android devices will work (If they're not designed for Android, they'll show "Charging (USB)" in the battery monitor, and will only charge at 500mA). The brand isn't really important, as long as it's a reputable brand. (...and before you ask, yes a 2A charger will work fine too, but will heat your battery more than a 1A charger.)

Ok thanks...I guess ill continue to use my samsung 1a charger since it works. And I know that I wont have this phone for the whole 2 years, but if I charge the phone every night anyway why take the risk of damaging the battery at all with a stronger charger when I dont need it right?
Anyway thanks for the advice and ill keep using my samsung charger.

The quick charge technology is designed to quickly charge your phone without reducing charging cycle performance
Hi! I bought a wall charger from Aukey that allow to charge up to 3 devices at the same time, what is great since I'll be able to charge the phone and the tablet at the same time! According to the manufacturer the charger is able to adapt the output to the needs of the devices! So my question is, can I use this charger to charge the GWR without damage the watch, since the output of the original charger is only 0.85A!
I think it should be fine. I have used my charger a couple of times without issue for my GWR and now my Huawei

I've been using an Aukey quick charger for a month now and no problems whatsoever. Normal charging times obviously (blisteringly fast on S6 however)

So I don't need to hurry about the output current, or in other words, get the watch too much warm and reducing the battery life?

It is completely fine. The charging circuits of these devices (watches, phones, tablets etc) takes only what it is allowed by the limitations set to the charging IC circuit when supplied with 5v power over USB. I have an USB amp meter and the GWR barely uses half of the original chargers 0.85a capability. I've used my OnePlus One charger (a high quality 2A charger) to charge my watch as well occasionally, which also charges my Nexus 7 2013 regularly and that never takes more than 1A~ from this as well.
I've been using a Aukey Charger for a couple of months and no problem so far. The current regulation is supposed to be made by the device, not by the charger anyway ...
For those who wonder, I also checked if our G Watch R has QC 2.0, but it doesn't. It still charges at 5V on a QC 2.0 slot.
I've just come over from a Samsung s8 plus that was unfortunately stolen without insurance and couldn't quite bring myself to fork out another insane price for another one. Purchased this OP5 carrier free @ my local o2 here in England (as i had a £150 voucher).
As a consequence, I have accumulated a large amount of both Quick Charge and Samsung adaptive fast chargers.
It seems that the OP5 charges very quickly on these which relieved me, I would say def on a similar level to QC 2.0 and the Samsung.
of course the Dash charge is just ridiculously quick.
i was reading that the OP5 does not support quick charge and only dash charge.
I beg to differ?

I'd be hesitant to use a QC adapter with the OP5. You're taking a risk of damaging the battery, or worse, the phone. There are most likely slight difference in the charging logic between the two adapters. I'd email OP support to get more info.

seems to work just fine, i doubt an adaptive fast charger will cause damage as it will act like a regular usb charger. will ask- cheers
Different charger wont damage anything people.
Lithium based charging system is more complicated as acid or Ni based battery, but simple.
1 rule for the power supply, it need to keep the power output the more stable as possible. So use high qality charger, samsumg are just fine. I'm using a HTC.
You can take any charger you want @ 5v. from 0A to 4A. You can use a 100A, but the phone will draw only waht it need, and the wire gauge will limit the power draw.
Let say the wire is too small, the voltage will drop, the chip will detect it and reduce the demand.
dash charging or fast charging are just brand name, the physics is the same. The power supply has a higher wattage, because the device can take it.
And the USB wire has a higher gauge compared at standard.
Use dash chager on a old phone, and you wont have any benefit if the phone draw only 700mA.
Or simply take a desk adjustable power supply, set it @ 5v4A, plug OP usb cable or any big gauge USB, and OP5 will show ''dash charging''.
Conclusion.
Depends of the voltage/amp/gauge, not the branding.
** BTW , even with cheap power bank, power supply or any supply, I really doubt it will damage anything. On my wife op3, we use any bank ( even the budwizer one), we plug it with iphone supply, 120voutlet with the usb option, dash, kindle supple, etc. annnnddd it still working juste fine. She has, ebay cable also.
Well all the stuff is in the charging brick on the dash charger. All the heat it's dealt with in the brick. That means the brick from Sammy doesn't and more heat then the phone could safely handle may do damage over time? IDK but the we all know heat kills electronics.
I use a quick charge (the one of got for my Nexus 6P) on my op5 but only at my couch so I pull it off the charger when full, don't let it sit on charge when 100%
You can let it sit on charge at 100%. Phone will disable charging anyway.
i actually think OP have stealthily allowed the qualcomm quick charge to work as it charges almost exactly as the s8 did on the sammy brick. i used a non quick charge old LG brick and that charged waaay more slowly.
honestly someone charge using a quick charge or sammy adaptive fast charge brick and tell me if im right or wrong ...

I only have my dash and 1 Sam qc brick rest are cheap but with dash block it obviously says dash charging, with the qc it just says charging, and with the 3rd party bricks it says charging slowly. So hope that helps
Just download an app like ampere and monitor the current using the different chargers, then you will see if it's more efficient or not.
It might charge quickly using those other chargers but the heat won't be transferred to the charger like it is with Dash charge
Likely it is QC2.. only with dash charger it will go further and faster
any 3rd party cables that are dash charge compatible?, read somewhere its based on the thickness of the wire ...

But this is just plain wrong, dash charging has nothing to do with QC quick charge. It's as different as it can be!
QC quick charge:
The brick highers the voltage to more than 10v. This way, less amps go through the cable, the the wires can remain thin.
(P=U*I) --- e.g. --- Power = Volts * Amps --- example: 5v * 2a = 10w / 10v * 2a = 20w
This way, you can have a greater power while the amps remain the same, while using a normal, thin cable.
The voltage regulator/BCM in the phone takes the voltage down to safe levels for the battery. This creates alot of heat inside the phone, which is bad for the battery.
Dash charge:
Dash charging transfers the BCM to the charger, little to no heat is generated inside the phone!
The BCM controls the flow to the battery by altering the voltage.
U = I*R --- e.g. --- I = U/R --- e.g. --- Charging amperage = Voltage / Internal resistance of battery --- e.g. --- When the voltage is pushed up, the flow into the battery gets higher.
Remember, this is all done in the power brick, so the voltage of the electricity going through the cable is lower (3-6v I would say).
This translates to a higher current (amps), So the cables have to be thicker! That's why dash charging only works with official oneplus cables (and some OPPO cables, but those are all Micro usb).
In other words, there is no way dash charging works with other powerbricks!
I hope this clears up all the misunderstanding surrounding quick charging techniques.
Cheers!

yes i agree but it seems like the OP5 allows qualcomm quick charge (or some form of it) to work as ive checked and a quick charge brick charges much quicker than a regular non quick charge brick.
this seems like great news as the phone has a versatility between both techs. makes commercial sense for OP to allow QC (albeit at the same level as a S8 from my experience) to work as their dash tech limits brick and cable usage.

yes i agree but it seems like the OP5 allows qualcomm quick charge (or some form of it) to work as ive checked and a quick charge brick charges much quicker than a regular non quick charge brick.

Yes, you are right, it could be possible (although unlikely) that oneplus has adopted 2 fast charging protocols in the oneplus 5.
I was just saying it can't dash charge using a samsung adaptor/cable.
I you want, I can try to hijack some cable to read out the voltage when the oneplus5 is being charged with a samsung adaptor.
That would be very interesting to see !!
Can't seem to get it to charge as fast as the OP5 charger, will post ampere reading here in a bit.

That's impossible, read my post above to see why
I checked the voltage while charging the OP5 with a QC charger It stays at about 5 volts, so there seems to be no QC capability in the OP5.
There is no QC functionality for the OP5. Regular charging, just draws power like a phone with neither QC or Dash. You can still get a relative fast charge from a higher output brick. (output 5v 1.2a-2a) Higher the amps, the faster the charge. Of course this is dependent upon cable quality and charge logic.
I have the Samsung 25w charger, and when using it it appears the phone will only either cable charge or superfast charge. It wont also fast charge. I want to maximize the battery life span of the phone, and cable charging is inconveniently slow, and I figured that fast charging would be a happy medium between that and maxing it out. I was under the impression that it's the phone that dictates the rate of charge it will accept from the brick, and the brick only determines the maximum deliverable current. If I understand correctly, we can use samsung's 45w charger, but the phone will obviously only allow 25w from it. I'm puzzled why when using the 25w charger the phone can't just accept 15w when set to only fast charge. Is this a bug?
Hi,
You might plug in your phone, Go to Parameters, Section Battery, Advanced Battery, and activate Super charge and superfast charge in order using fast and supercharge with your 45W charger !
Yes, I've done that. The 25w charger will only super fast charge, but won't just fast charge. I would have thought it could either one, whichever I have it set to do.
if you want fast charge ..... deactivate superfast charge should be the solution ! Isn't it ?
Probably a firmware/software glitch.
Fast charging will not enable if battery temp is too low.
To avoid Li plating the battery temp should be a minimum of 72°F or higher, the preferred minimum is 80°F.
Using the 45 watt brick may shorten battery life.
Fast charging with the 25 watt brick appears to do little damage.
Li's prefer brief, frequent midrange charges ie 40-65%. Avoid discharging below 30% and charging beyond 90% although 80% is a better top limit.

No, if you only activate fast charge (with superfast deactivated) and use the 25w brick, the notification in the shade says cable charging, and that takes like 2hrs to charge the phone.

That doesn't sound like fast charging is active. It should gain about 2%@minute through most of its range except the top end where it goes to about 1%@minute.
When this doesn't work correctly it's a true pain to troubleshoot. My 10+ started dropping out of fast charging prematurely. A new 25 watt brick/cable and trying a lot of other remedies still hasn't fully restored it.
I'm curious if anyone here has a 25w brick that could confirm if this behavior is present globally, or if this is something just on my device? Only activate fast charging in the battery settings, plug the phone in with the 25w charger, and look in the notification shade and see what the charge rate is tagged as. I'd be grateful if someone would confirm this.

I have noted that you practise the same charging procedures as I have done for several years (and you obviously have done as well). With my Note9 and S8 + I used to not let it drop below 40% if I can avoid it and also not go above 80%. All this is fine and most of this we all probably learned from Battery University and Isadore Buchmann. That all said, and I am really not sure if I am keeping this phone - Decision today or tomorrow - my question comes to the matter of calibration. When I received this phone some 14 days ago I charged it to 100% but thereafter did not run it down to zero but kept it above 40% the whole time. The question I put to you (and others can learn from your response) is there a need to "calibrate" the device initially (ie run down to say 10% for example once a month) as was suggested by Buchmann probably a few years ago?

You and I discussed this earlier. Do you think it is the port that has become damaged? Part of the reason for my getting the wireless charger is my Note 9 is very erratic when it comes to fast charging. Cleaning out the port with a toothbrush/compressed air. rebooting...wiping cache partition, new cable etc never truly fixed it for me. I do feel that when first plugging in the S21 ultra (before going wireless) the connection seemed a lot firmer.

It does appear to be related to the Samsung 25w brick. I have the one that came with my S20U. It will "Super fast charge" my S21U no problem. If I turn off super fast charging in the phone, it only says "charging" when plugged in, and with my phone @ 65%, it said it would take well over an hour to charge (forgot the exact time). Then I took my phone w/o changing any settings to a generic 18w QC3 brick, and it said "fast charging", and said it would take 44 mins to complete.
Ive seen this same type of issue as well with 2 different chargers. One charger (45w pd) will fast charge with super turned on but not fast, notification only says fast charge. The second (39w qc3) will fast charge with regular fast charging turned on, but turning on super does nothing. Charge times are the same with both chargers on regular charging and fast, with 0 differemce between fast charging and super.

I'm as clueless as you at this point unfortunately.
My port is good, cable/charger, tried hard reset, cleared system/akp caches, did the recall thing and so on.
I'm wondering if it's a battery fault. Do older batteries go into fast charging the same as newer ones? It's almost as if it's throttling the fast charging, sometimes it's full bore then it drops out to 1%@45 seconds then to 1%@minute.
Or is it a calibration ie it thinks it's at 90% when it's only at 70%?
The only I haven't done is a factory reset, lol.
All this started one night when it was slow charged to 100%. WTF?
TFF the curse of technological Beast!
Guess I'll try recall again.

Right on. Sounds like it's not just my phone. That's a relief. It's puzzling why the phone can't also fast charge with that brick. Perhaps it's simply a bug that Samsung either never noticed, or it isn't a priority to them. It would be nice if we could take advantage of the different settings without having to have two different bricks sitting around.
I think I figured it out. The fast charging setting is for the old classic fast charger. If you connect your phone to that one, you'll see it says it's fast charging. If you don't have fast charging turned on, it'll prompt you to turn it on to use that charger at it's maximum capability. If you use one of the newer Samsung C to C bricks, it's going to do the super fast charging.
I am currently using this Baseus charging plug and get full range of charging options - fast / super fast.
Thought I would try some I have hanging around before buying a Samsung one.

XDA just covered this in their article:
Fast Charging Explained: The slowest to the fastest Fast Charging technologies
Curious about fast charging? Here's everything you need to know about fast wired charging standards and how to pick the best charger!
www.xda-developers.com
Unless a charger has USB-PD PPS they will only FAST Charge @ 18w with fast charge on (super fast on/off wont matter as it will be off). If you are getting super fast charging then you are getting the expected 25w which is totally fine and not bad for battery. You will get super fast with the samsung 25w adapter and maybe the previous series 45w adapter.
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

No huge charging improvement. It most likely will degrade the battery faster.
I use only the Samsung 25w bricks because they are known good and relatively cheap.
Just picked up a 25w brick and cable for $20.
The amount of trouble a defective charging hardware can cause means I won't consider using 3rd party chargers/cables for fast charging.
Fast charging is a nightmare to troubleshoot as I'm learning now... will see if a couple full 100-0% charge cycles get it or not.
It's time consuming and irritating.

Thanks for posting the link to that article. It clears some things up. Charging standards have become rather confusing with all the proprietary standards. This makes me feel more comfortable using the 25w super fast setting on the s21 ultra.
