So the Z3C does charge pretty fast...if you use a different charger

I'm using a Samsung Galaxy Note charger with mine because I ordered from UK and North American sockets are different.
Anyway, the phone charges fast, despite what reviews say, I'm just a bit concerned that it could be affecting my battery's life or something.

how long does it take to charge it? can you take a picture of the charger so we can read the description of the output?

The Galaxy Note 3 charger is 2A. I tried a Nexus 10 fake charger (2A verified, uses 15W from wall socket @2A with the Nexus 10 to provide 5V/2A (10W, not measured)) while Sony original 1.5A charger uses 9.3W to provide 5V/1.5A (7.5W, not measured). Connecting the Nexus 10 charger to the Xperia Z3 compact it uses only 9.4W so it only take 1.5A or less even with an high gauge USB cable.
Therefore I would say that the phone never uses more than 1.5A no matter what's the charger.

Usually LiPo/Li-ion batteries support 1C charge without problem (as long as the charger slows down at the end). The capacity of the Xperia battery is 2600mAh, therefore 1C would be 2.6A, with a 2.1A or 2A charger you encounter absolutely no risk. Also even using an higher current charger, every phone (with a lithium based battery) integrates a charge regulator which will limit the maximum current according to their specifications. Therefore higher amperage is not a problem as higher voltage would be, it's more the highest current the charger CAN provide, not it actually provides.

It will charge even quicker, as the phone(Z3 and Z3 Compact) is Quick Charge 2.0 certified, you will just need to get a charger that is Quick charge 2.0 certified as well (i.e. Moto Turbo Charger). Feasibly, it could be charged in 45 mintues form 0-100%.
The charger will be my next purchase.

Not sure what's considered fast or slow when it comes to charging, but just using a generic USB charger with wall plug-in adaptor (as I do with all my phones without issue), I'm fully charged after a complete drain in about 2 hours. However, if there is some magical charger that can do this in 45 mins, I would totally invest in that!

Nice. I'm assuming there must be an 801 variant. Let us know how well it works when you do get one. For now I don't mind the slower charge since I leave my phone plugged in overnight, but I can forsee occasions where I would need a speedier solution.

You could use any tablet usb charger, they charge faster

I get about 900-1100 mAh with my magnetic charger. It takes about 2.5 hours to charge my device.

So youre saying that the Magnet Charger is significantly (33%) slower than the Micro Usb? Lame...

Yup. it's more of a convenience factor. I dislike opening the side panels and I usually just charge overnight w/ the dock (which also charges at the same rate).

I thought unk3 was maybe referencing a quick charger? The only thing aside from the quick charge that charged faster, was Samsung's. I think my old S5 was getting 1800mAh.

I think he was referencing 900-1100mAh vs. 1500mAh of the stock charger. So to correct it there is absolutely no difference from a technical point of view between USB or magnetic port, there are not more less losses assuming the quality of the cable is the same, it is just a different plug. The magnet only holds the plug, the connection is wired and not inductive therefore efficiency is.the same.

there can be a difference, because magnetic port does not have the 2 additional pins that phones like to use to identify the maximum current they can draw from the charger, so...

This is Apple BS to explain the incompatibility of their iPhone with most chargers on the market at the time. The phone does not need to identify the charger max amperage at all,the charger is simply a 5V DC power supply with a defined max amperage like a wall outlet provides 110V or 220V AC at max 10/16/20/32A. The charging circuit of the phone does all the job: transform 5V to 4.2V and then regulates the amperage going to the battery at constant voltage. There is a difference with a wall outlet though, if the rating is lower than what the phone requests then the charge will simply be longer and the charger will not burn (at least if it is lawful).

It definitely does need to, that is, if you want your phone to draw more than 500mA. USB standard does not allow a device to draw more than 500mA from the port, and all phones conform to that. That's why it charges slowly if you plug your mobile phone into a computers USB port, the internal charger circuitry inside the phone limits the maximum current "ceiling" that it will try to draw to mere 500mA.

You are correct on the defined max amperage part. Every DC power supply has it's maximum current limit, just like ordinary computer USB port (which can supply max 500mA, if you step higher than that, the current overload protection in the computer shuts the port down (and windows will give you an error about a power surge on USB port X). That's precisely why a phone must identify if the power supply that it is connected to can give higher than 500mA current, as to not overload it.

Yeah, many cheap ones will overheat (shorten the lifespan of electrolytic capacitors, etc) and even burn. And even some that are not cheap will burn. Others will be periodically shutting down by internal thermal protection, then turning on again after it cools down, this is not good either.
If you use a magnetic charger then the phone loses the ability to identify if it's connected to a computers USB port, or a charger that can supply more than 500mA. And in this case it will stay on the safe side and will not try to draw more than 500mA (charge slower) from the port.
As for the identification, you can check that pins 2 and 3 are shorted in the charger's USB port, that is how the phone "knows" that it is connected to a charger with high current ability. You can get some spare USB cable and make an experiment, cut the wires that go from pins 2 and 3, and you will see that the phone will limit the current to 500mA.

Experiment done: I beg to differ, the phone draws 1.5A from the magnetic port, see attached picture (it is the current drawn from a 2S battery at 7.62V so roughly 1.5A at 5V. Also this circuit can provide 2A at 5V which means that the phone never draws more than 1.5A no matter what the charger is.

The fact that data lines only indicates it is a charger and not a computer, data lines at not shorted but connected to a certain resistance function of the amperage of the charger if they follow the apple scheme.

Quick Charger 2.0 not working on Z2

Hi guys,
I have an D6543 (Brazilian Model), there is no difference between D6503.
I checked the Qualcomm website a lot of times, and Z2 is in compatibility list: https://www.qualcomm.com/products/snapdragon/devices/all?feature=Quick Charge 2.0
So, I purchase the Tenergy Quick Charger 2.0 at Amazon, and for my surprise, it's not working at all. Only normal charging.
I tested at 1%, and in 30 minutes only 11% was charged, VERY, VERY slow.
The light indication at charger is saying that is on normal charging.
I'm really frustrated.

Fastcharging is disabled on xperias for safety
Charging should be between 1-5 hours even without fastcharge

My z2 only take around 2 hours to fully charge from 1%. Just using the stock plug charger.

It charges at 1500mAh using the factory provided charger and trying to go beyond that isnt safe at all.

I don't know why. Z2 has the Snapdragon 801, which is compatible with Quick Charger 2.0, as Z1 was compatible with QC 1.0.
LG G3 also has the 801, but LG does not enable the QC, that's why it is not at Qualcomm's website. It's weird, because Z2 was recently added to the list, and the main product page says it's compatible.
In the end, I just lost money because their poor support and information.

Not exactly poor support, if its safe to use and certified safe to use sony would have put it in the features list on their website but it wasnt there when i bought the phone nor when i last checked.
As said check my reply
The device charges at as fast as it safely can with the factory provided charger

I'm using envi rom.
I have a normal 2,2A usb charger.
When I use the usb port to charge i have really slow (6h from 0 to full charge) to reasonable charge time (3h from 0 to 100) depending on the used cable.
But when I use the magnetic aftermarket cable than I get insane charge time, only the last 10% from 90 to 100 is not fast but it certainly uses 2A as it is from 0 to 90% in about 90 minutes.
The phone gets slightly warm but far from the temperature it gets with intensive usage and the magnetic connection gets warm too, but nothing alarming imo.
The full metal and glass design makes heat diffuse very fast.

That sucks I'm coming from a one plus one and the charger was very fast.

Xperia Z2 and Z3 supports Quick Charge 2.0.
You need charger which supports Quick Charge 2.0, though.
http://weekly.ascii.jp/elem/000/000/223/223383/
This site is in Japanese, but it says you'll get 13W when you charge with charger which supports Quick Charge 2.0 and with normal charger you'll get 10W.
Normal charging is already fast enough, so you won't notice big difference.

Either they know nothing about electronics or they cannot calculate ^^
1. it should show 9W..... 1.8A x 5V so their meassurement device is not exact (hell, these Wallplug meassurement things are made for 220V ! so you measure 0.045A you can't expect them to be realistic, they're for up to 2000W not so low values.)
2. 9V x 1.8A = 16.2W but this is wrong again as the Quick CHarge 2.0 speccs are up to 4.5A for 9V
So if it really is charching with 9V it only uses 1.44A
Oh... and btw the Stock Sony Wall charger EP880 only has 5V 1.5A
Let's hope some people who know what they're doing are gonna test the Z2 or other phones with Quick Charge 2.0

I'm unsure about the battery but this is why QC 2.0 utilizes a higher charge voltage. Also why in computers, all high current devices now run on the 12v rail instead of 3.3v or 5v, because high amperage at low voltage would damage cables and connectors. If we had expensive graphics cards pulling 400w at 3.3v there would be a huge problem with heat and necessary wire size. There is more resistance in metals with high current / low voltage vs. high voltage / low current and this is what can damage the USB port.
This is also why at 120v AC we have issues running high current draw appliances vs 220-240v circuits.
Also why high voltage is more fatal, because it travels more easily through our skin, and etc.

I contacted Qualcomm by email, and they replied to me after a few days.
Xperia Z2 officialy does not support Quick Charger 2.0, only in JAPANESE models.
They updated their website, and removed the information, that's sad.

FYI guys, Sony Brazil sells Z2 and Z3 with Smartband, so, our OEM charger has only 0.8A :crying::crying::crying:

Just purchase some charger with 5V 2A output and you will be fine..

Hello,
quick question: is it safe to charge our Z2's by S5 charger - 5,3V and 2,1A?

i dont get this. If the stock charger is 1500mA and the batery is 3200mA it should take only 2h10 to fully charge(more or less). But mine takes like 3h (brand new phone, charger and cable, all stock)

yes its 1500ma with a 3200ma battery but concider the cpu. your phone is awake for 25% of the screen being off so it should take a over 2hrs10m to charge unless you have xposed amplify installed.

Not All USB Cables Are Created the Same

I've done some testing on the best ways to charge the Nexus 9. Here's what I've found...
a. You'll want to upgrade your kernel.
The stock kernel for the Nexus 9 does not support charging over 1.5a, I'm using Elemental X which supports up to 2a.
b. Use a charger between 1.5-2a.
I'm using the Insiginia rapid charger from Best Buy.
I've tested 4 different cables to see the amp output from the charger with the new kernel using Ampere. The stock charger from the box, my Moto G LTE charger, an Insignia charger and a generic charger from ebay. The results are as follows...
Insignia Rapid Charger @ 5v/2.4a
I read the readings with the screen on 40% brightness and let them each sit for 60 seconds.

Min is the minimum amperage the cable hit, max in the very maximum and avg is the average at which the output sat around.
As expected, the stock usb cable performed the best, while the generic charger was very unstable and wild (I probably won't use this charger anymore as a result).

Interesting about the kernel.
Also your title says cables then you talk about chargers. Cables can also make a big difference in how much power your device gets. What cables did you use?
*EDIT*
Ahhh i miss understood. you where switching cables not chargers.
you probably were seeing this http://lifehacker.com/cables-can-significantly-impact-the-charging-speed-of-y-1532784722

Thanks for this. Was wondering how much the cables mattered.
I tested my stock charger and cable. The average amps are 850-1100 mA. It's mostly around 980 mA, and the max I've gotten is 1160 mA. Doesn't seem to go beyond that.
I also tested a nokia cable with the stock charger that is 1.2 meters and got quite different results. It charges with the average amps at about 450-550 mA, with it mostly at about 500 mA. Max I got was 740 mA. Not using that cable again...
Kernel is FireIce which supports 2A charging, and brightness was at about 40%. Voltage was read at about 4.02-4.11V for both.
Gonna have to find a charger with a 2A output.

I also misread the post the first time. Thought he was talking about chargers, when in fact he was talking about the cables for the chargers,

Sorry about the confusion, should have said 'Insignia Adapter' lol I'm curious about some of the other chargers I have lying around the house now.

i had learned this with my asus t100 wintab. that thing is picky as hell when it comes to cables. one of the best cables i've used are the ferrous monoprice ones. shorter is better. samsung's stock cables are just as good.

Using an iPad charger with a 12inch sony headphone charger cable and getting around 1480mah on average. Using Elementalx kernel.

Weird thing is that I also tried using the note 3 charger with a lot of cables including the stock and got slower charging than the stock charger!
I might just invest in the cable mentioned above to see if it helps.

same here. the best cable/charger combo i've tested is the stock samsung charger and 3' cable (not sure which box it's from since i've had so many galaxy devices, but they're all the same). the 5' cable hits about 1400. using a monoprice 6ft cable does just as good as the 5' cable. i have a 3' monoprice in the car but too lazy to get it to test it. the best generic cables i found are these:

Not a surprise. Many (most I suppose) of the cheaper cables simply dont have thick enough wire, too much resistance. For decent and cheap cables I like the Amazon basics cables. The newer USB3 versions have thick gauge wire so the 6 footers charge at full speed even with devices that support high amperage charging.

I'll keep that in mind about the amazon basics brand. Im just using a cheap china made brand, (i dont know what brand) and they charge pretty slowly, but it's alright. If the device is dead, I'll plug it in, and it'll be charged by morning. I don't really need anything too much fancier or faster than that.

The "basics" cables are a real bargain. I am very careful about the cables I use these days after my wife used a cheap cable on her N7 and it shorted out on the connector and roasted the pins on the device. Not sure how that happened but I suspect a very sloppy fit didn't help.

I'm using a monoprice cable (6ft i believe) with the oneplus one charger, and it works perfectly. The monoprice USB cables are among the best I've used; they're durable, reliable and the springs seem to keep their tension over time, something I've found that cheaper USB cables can have trouble with.

OEM Charger & Cable nother Quick Charging. Phone says it is.

From my understanding when the battery is lower than 50% the Stock OEM charger is suppose to feed 9v at 1.6a. And after 50% it's supposed to drop back down to 5v 2a. My stock OEM charger and Cable does not go to 9v at all. I didn't see the charger go to 4v. Would not show amperage.

Yes I do. And it says fast charging when plugged in in the notification menu and on the home screen

Try a diffrent app i noticed u were using ampre i was getting eronnous readings on my g4. U mqy have to set some of the variables in ampre cause of the way it reads
It always says my g4 is charging at 500 mah. And i know its not true. Everything else said 1.5 amps

I use 3c toolboxes battery managerbut still has to be tweaked for rite readings
also if samsungs anything like lg when the screens on it don't fast charge normally to keep the heat down
like rite now my fast charge is only 1.5 amps
its always changing it might fast charge for 2 or 3 min then drop off for 2 or 3 min kind of thing
I personally don't like fast charge its hard on a battery the slower you charge em the longer they'll last
imo
just like a car battery slow charges are always better

I normally turn my phone off when I'm charging the battery because it charges so much faster and the heat and stuff. So I'll leave it off till it's done or close and take it out of the case. It doesn't take long so I don't mind doing that. I got looking into this because I was looking to purchase a new cable and wanted to be able to compare and make sure I was getting the same charge times.

Idk I'm not really into the entire idea. Yes it's nice. But when I know I can get a faster charge plugged in it just seems useless.

Actually, I use the computer (either my desktop or one of my notebooks) to charge my devices (Galaxy Nexus , Lenovo tablet, and Galaxy S7 that is awaiting pickup by its owner). While the two Samsungs both support wireless charging (yes - the GNex does as well - as long as it is running MM or later), I prefer wired charging.

Hearing that you use your computer to charge your devices is like screeching nails on a chalkboard to me ?

Do you use your (smart)phone when at your desktop? I usually don't.

Why is that? As long as your computer supports USB 2.0 (and unless it's older than Windows Vista, it likely does) and your phone or tablet is *newer* than the Samsung Galaxy Tab 2, it's a standard feature (of both PC and phone - the same also applies to portable computers - such as laptops and notebooks). Yes - it's a trickle-charge (compared to plugging it into a wall charger or cigarette lighter) - however. I'm more than likely using my PC while the devices are plugged into unused-otherwise USB ports - it's not like the USB ports they are plugged into are doing anything else. (In short, I'm not sacrificing USB ports to use them for that purpose - out of the ten USB ports my desktop PC supports, I'm only using - for all purposes - six; I have four headers that I am not using at all.) On top of that, most USB chargers for Android devices are of the "wall-wart" type OR are cursed with short cord length - or both. (Yuck to both.)
I don't need a fast-charge - and especially not when I can top off using a trickle-charge while not using my phone OR tablet - and I'm usually not when I'm at my desktop PC.

Nexus Only Reading 1.5A charging

I did search through the forums and didn't find anything that applied to the issue I'm having. I bought a 6P off Ebay for a good price, but it didn't come with any accessories. I don't have a C-C wall charger, but I did buy what I thought was a decent one with a C-C cable for my car. The charger is made by Satechi, and the cable is made by Belkin. They both specifically say on the box that they support fast charging, the cable up to 60W, the charger up to 36W. When I tried multiple amp monitors on my phone it only said that it was hooked up to a 1500mA charger. Plugged it into my USB battery pack which has a 2.4A port, same thing. Now, in my experience with computer hardware most of my hardware problems are generally software problems, and I'm wondering if installing Lineage on this thing has eliminated my ability for fast charging. I've done lots of searching (my Google-Fu is terrible) and there's no real mention on if fast charging is up to the hardware or software. Does anyone else have some experience with this and can maybe guide me through some things I can look at?

I know that ampère (app) says Max 1500mah too when I'm connected to my stock charger, but the charge rate goes well over 1500 mah (around 2500-2800 or something). After hitting 60% or something it slows down. I also know that lineage os on the nexus 5 says "charging slowly" on the lock screen, while the charge rate is normal.

I had a similar thought so I drained it to about 25% and then charged it back up. Fastest charging rate I saw was 1250mA.

It's hard to say whether the app, charger or cable is letting you down here. The 6P charging cycle has many steps and it will only pull maximum current from empty to about 30%. Next time you discharge the phone, pull it down to the single digits and then check current again. My stock charger will put out 2.7+ amps when the phone is fully discharged. (I used Accubattery). What you should also know is that the phone will continue to charge for 45 minutes or longer even when the phone says 100%. If you are interested, you can read more in an early Anandtech article. Scroll down to the "Charge Time" paragraph/graph. There is a lot of misinformation around the USB-C standard, and ton of crappy chargers and cables that do not meet the USB-C standard or make claims that independent testing does not back up. A Google engineer named Bensen Leung has been lab testing cables and chargers to try and provide some clarity. For car chargers, he currently favors the Nekteck 5.4A . Lastly, there is much more discussion on chargers and cables in the Accessories sub-forum.

Well, I tried it with the app you mentioned and it said (at 9%) at I averaged a 1350 mA charging current. I almost need to find a charger belonging to someone else that works on their own Nexus and then try it on this one.

@Caboose27
Good you tried a different app to rule out a particular app. My guess is that one of your components is not living up to it's claims. Look for Benson Leung approved cables/chargers and you won't be disappointed. Have a look through the Accessories sub-forum to find good stuff tested and endorsed by other folks. Good luck to you, and welcome to the exceptional Community of the N6P. You chose a good device.

I did look through the Accessories forum, and I found a post about a USB charger that's basically exactly what I'm looking for. But it was a year old and he never wrote if it worked or not, hence me starting this post. I appreciate your input though. Most of the stuff on the sub-forum is about wall chargers, and I'm specifically looking for a fast charging car charger.

See https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf (the only not so funny thing is that it doesn't mention Nexus 6p)
Will receive my car charger tomorrow and I only discovered this document today.
Lucky me, the charger is mentionned So is your Satechi.

It doesn't mention it because the Nexus 6P does not support Qualcomm's QC3 or QC2 at all. Hopefully the car charger you bought (you didn't specify) has a native USB-C port or a permanently attached USB-C cable that outputs 5V/3A. Otherwise your QC3 charger will only output a maximum of USB-A which limits you to either 2.1 or 2.4A. A review and test results of many USB-C compliant accessories can be found here.

It does have a USB c cable and outputs at 3A.
Good spot on 6P not supporting QC while chip is a Qualcomm
Haven't seen many reviews. Will give feedback if it exploded.
edit: I finally have had time to test it. Works great.

I bought one and it arrived over the weekend. It works great, and it actually seems to run a tad cooler than my standard two amp charger.

Good to hear
