Quickcharge 2.0 with Sony Xperia Z2 Tablet

I've been using my HTC Rapid Charger Quick Charge 2.0 with my new Sony Xperia Z2 Tablet and it charges in just under 3 hours for a 0 to 100% charge.
Not sure what the standard charge time is with the stock charger, since I haven't even taken it out of the box Just easier for me to use the same charge and cable to charge both my phone and tablet. Has anyone else measured that?
My HTC One M8 usually gets quite hot during quick charging, but didn't notice the same thing with the Z2. It only went up to around 35 degrees at the highest, for a short while.

I need 4.5 hours with stock charger (15% to 100%).

So 2.0 quick charging is working?
Do you really get 60% in first 30 minutes with HTC charger?

Yes, it's listed here:
https://www.qualcomm.com/products/snapdragon/devices/all?feature=Quick Charge 2.0

Does anybody know where to buy a quickcharge 2.0 charger with a euro plug?

No, those 60% in 30 mins is claimed with a much smaller phone battery..not with our 6000 mAh tablet battery. On my HTC One M8, it gets to about 50% in 30 mins.

Are you from Denmark? I bought mine from here: http://www.mytrendyphone.dk/shop/htc-tc-p1000-164522p.html
Not the cheapest option, but the only one with euro plug that i could find.

got official answer:
Thank you for contacting Sony Xperia Support.
To be able to utilise the Qualcomm Quick Charge 2.0 technology, the smartphone or tablet as well as the charger need to support Quick Charge 2.0. If you want to use a magnetic charging dock, this must also support Quick Charge 2.0.
Currently, there are no original Sony chargers that support the Qualcomm Quick Charge 2.0 technology. This means that, at present, you cannot charge Xperia™ devices using original Sony chargers utilising Qualcomm Quick Charge 2.0.
However, some Xperia™ devices and magnetic charging docks are prepared for and support the Qualcomm Quick Charge 2.0 technology. Again, as there is currently no original Sony charger that supports Quick charge 2.0, these devices cannot utilise Quick Charge 2.0 using an original Sony charger.
Regarding the charge time, according to our environmental declaration a full charge takes 5.8 hours while the tablet is turned off.

Wow, a normal full charge takes 5.8 hours? Even with tablet off..that sounds a bit crazy. Then im definitely glad i'm using the Quickcharger and getting it done in half that time..even with the tablet powered on.
As for the magnetic charger, it has been confirmed in other Xperia forums that Sony's dock and magnet supports Quickcharging, but most 3rd party ones don't. I'm using some cheap magnetic connector from eBay, and it charges quite slow (and half the times the magnet doesn't even keep it connected and it keeps falling off )

from my experience tablet charges in 4 hours (even if it`s turned on, from original SOny charger 1.5A 5V), from 20-30% to full. So this estimation is correct.
Anyone can recommend a good ansd cheap charger that support QC 2.0 or there already some thread about this on XDA somewhere?

There is not really any difference between all of them, as long as they are certified by Qualcomm to work with QC 2.0.
There's a list of all certified chargers on this page: https://www.qualcomm.com/products/snapdragon/quick-charge

and here is an especial cheap offer http://www.androidauthority.com/quick-charge-explained-563838/
So... do ALL z2 Tablets support QuickCharge 2.0 ? Because only the Japanese Z2 Phone supports Quickcharge!

Cool.

My quick charger that came with my samsung galaxy s6 initiates rapid charging on my z2 table, it even says rapidly charging when I plug it in

[Q] Best Car Charger

I am looking for best car charger, my phone will be all day on in the car, and I am looking for best solution for charging in the car, and fastest.
I found few good chargers but not sure are they support quick charge
Samsung OEM ECA-U21CBE Micro-USB 2-Amp Rapid In-Car Power Charger
and
Car Charger, iOttie RapidVolt 5Amp/25-Watt Dual Port USB Car Charger
Or is there some third better solution? Sorry I can't post links
thank you

anything above 2A is consider fast/rapid charge and barely any difference than the "quick charge" not to mention, saving a few mintues might do more harm than good to your replaceable battery.. at 2A, the phone will go from 6-10% battery to 50% in about 25 minutes.

Ottie:

I have the Anker and would buy it again, and has tons of positive reviews..

Thank you, what about Verizon Quick Charge 2.0?

I have used Verizon QUALCOMM version and would recommend the quick charge version if you want to take advantage of the quick charge. If time to charge I not an issue then obviously any high amp charger like the units cited above such as iottie would work

Is quick charge healthy for battery in my case? Or maybe should I get slower one?

I am using the Airdock.
While I can't say I loved it with the S5 (was falling off) the flat back of the Edge fits perfectly on it so I'm much happier with it.
Fun streaming video, back passengers can watch video off of it with the car speakers...
works well.

faster charging will always put a bit more wear on battery than charging at a slower rate. most people here will probably swap devices often so probably doesn't matter for them. if you plan to keep your device for a few years and want max battery life then maybe use a 5V 2A charger instead (one that i've linked to above).
2A is still "fast charge" the only difference is it's Quick Charge 1.0 which is at 5 Volts compared to Quick Charge 2.0 that runs at 9 Volts.
better example:
Quick Charge 1.0 - 5V @ 2A (5V * 2A) = 10 Watts of power
If your phone is at around 8-10% you'll get to about 50% charge in about 30 minutes.
Quick Charge 2.0 - 9V @ 1.7A (9V * 1.7A) = 15 Watts of power (up to 12V * 3A = 36 watts for some tablets)
If your phone is at around 8-10% you'll get to about 50% charge in about 20-25 minutes.
Quick Charge 2.0 will only be a little bit faster once the battery gets to around 50-60%, then it will throttle down to Quick Charge 1.0 rates to keep the battery from getting too hot and causing excessive wear.
All Quick Charge 2.0 devices are also backwards compatible with Quick Charge 1.0, meaning that you can use a Quick Charge 2.0 device with a Quick Charge 1.0 supply, and visa versa.
In short: Quick Charge 2.0 will only save you about 15 minutes to completely charge your phone compared to the normal 5V @ 2A chargers.

Get Verizons branded car charger with fast charge. Workscexcellent, and AND has a little flashlight right above the micro charge plug, which comes in super handy in dark car. Very well made.

I bought this one. Didn't fully test yet but when I plug this, it says "fast charging". It would be better if this has light notification. But it's good that it charges fast.

QuickCharge 2.0 tests

I bought a few QC2.0 chargers for my AT&T G4:
2-pack Samsung Adaptive Fast Charge AC chargers: .walmart.com/ip/45734981
Tronsmart Dual Car charger: .ebay.com/itm/191645992162
Aliexpress knock-off single QC2.0 car charger: .aliexpress.com/item/Qualcomm-Quick-Charge-2-0-Stand-USB-QC2-0-Car-Charger-for-Samsung-Galaxy-S6-HTC/32364542508.html
..... and compared with the performance of the STOCK LG G4 1.8 Amp (non-QC2.0) charger.
[Note: front end of URLs ( h tt p : w w w.....) left off since newbies like me can not post external links]
I charged my G4 with power OFF, and used Battery Monitor Widget
( play.google.com/store/apps/details?id=ccc71.bmw )
to measure before and after % remaining,
I "generally" began the charge cycle when the %remaining was low (3-16%, 11% average)
and charged for about an hour (52 minute average)
For each I repeated the test 2-3 times.
Here are the results:
Stock Charger: 1.033 avg, 1.04 max % per minute
Samsung: 1.249 avg, 1.300 max % per minute
Tronsmart: 1.248 avg, 1.290 max % per minute
AliExpress: 1.221 avg, 1.270 max % per minute
So.... even though QC2.0 CLAIMS to charge up to 75% faster, my results were closer to 25% faster
All the QC2.0 chargers were rather consistent in their performance.
I found ambient temperature was an important factor.
The 1st test with the AliExpress was done in a closed car on a 110F day (without AC on)
I got 0.25%/min - but disqualified this result due to the temp extreme
(All other car charger tests were done with car running while driving with AC on)
I'd be interested in seeing if anyone else can test their chargers similarly and post the results here.

Que QC 2.0 on the G4 is a joke, it barely doesn't even exist.

I can't even use my quickcharge 2.0 charger. Anyone know why that may be the case? I'm on software version G, the charger works perfectly fine with my note 4 for quick charge but not on the G4... It's a GETWOW qualcomm quick charge 2.0 charger

Your battery is 90% full, is it any different if your battery is lower, like 10%?

My Keedox qc 2.0 is charging my g4 faster than my ex-m9! It can fully charge from 45 to 100% in 30 mins only, it was 50 mins with the m9!!!

No complaints from my Quick Charger

Ive got the uk plug aukey single port quick charge 2.0. Did a timed charge last night 14->48% 25minutes (1.36%/minute), 48->71% 16 minutes (1.44%/minute), 71->92% 19minutes (1.11%/minute) - total time from 14% to 92% one hour (1.3%/min) so about the same as OP test.

With custom kernel we should be able to reach much higher charging rates...on g2 with dorimanx kernel i never saw anything below 1600 and got up to 21xx

Agree. I use aukey QC 2.0 3 port. Using QC 2.0 port, or just the same charging time using stock charger. From 5%-100%, both need time about 105 minute. No different. I sold my aukey.
Aukey using 9v (8.9v exactly) and 5v for stock charging.

Which FAST charger I should order for my new Huawei P9

Hi to all
Just ordered a new EVA-AL00 from eBay last night. I am living in Canada. May I know which charger I should order to take advantage of the quick charging capability of the P9 ?
Is P9 using QC 2.0 or 3.0 ?
Please kindly advise ASAP.

HI
wrong! fast charging is supported by huawei fast charger
but only with this charger i tryed with asus 5v2A/ 9v2A but dont working

anyone who can provide a link to where i can buy one with an eu plug?

I'm considering buying this phone over the S7 (although still undecided) and I still don't get the battery thing (charging or battery life, I get people telling me all sorts of contradictory things that I'm having a hard time to fact check). That 9V/2A charger doesn't come with the phone, right? How much faster is that Huawei charger compared with the 5V that comes with the phone and what is it called since I can't find it on their site or anywhere? Is that the Mate 8 charger?

Yes it's mate 8 charger

Well, no EU plug still available. But it will be later I think. It is not QC 2 or 3, it won't work. Search for "Huawei 9V 2A Charger".
The result should be like this: http://www.ebay.com/itm/Original-9V...hash=item280f7d97a4:m:mNQwKZr7I5KHReS9CA2RwkA
As I metioned, no EU plug yet, so via adapter only.

It's fine, it will charge as a standard charger at 5V. I would have to brush up my Ohm's law but I don't even get why Huawei's standard charger on the P9 has 2 Amp electric current value. What matters is the voltage going into the battery and you don't need a 2 Amp charger to give you 5 volts, a regular 1amp will be able to do that. The only difference I know is that 5V at 1 amp are 5 watts and 5V at 2 amps are 10 W. But that has only to do with resistance, I think, a battery isn't fed on watts?
I'm really on the fence about this fast charging thing now. I never got it. Qualcomm's has its QC 2.0 tech but a Motorola charger is faster than any other. An S7 Edge with amuch bigger battery charges as fast as an HTC 10 and the Edge has a 2.0 QC and the HTC is 3.0. The G5 is also 3.0 and charges way faster than the HTC, even compensating for the different battery capacity. And I own a G2 which has no fast charging at all and will charge from 0 to 100% in less than 2 hours on a 5V generic charger, which isn't very far off the times I see with 3000mah batteries and Quick Charge 2.0 or 3.0... Why these differences?? No idea... Somehow I think battery chemistry has a lot to do with it (it does in the RC and electronic cigarette world) but I never see anyone addressing that.

Nearly right! A little analogy may help... Think of Voltage (V) as the diameter of the water tap, Ampage (A) as the speed of the water through the tap and Wattage (W) as how quick you want the bath the taps are filling!
So you can see, a small diameter tap but high water speed will still not fill bath very quickly, neither will a big diameter tap and slow water speed...you need both together. So 9V2A should charge quicker than 5V2A (18W compared to 10W).
As I understand it the P9 will accept charging at 9V and 2A (their Fast Charging) giving max 18W input so a 9V2A charger should give the best results (which is what the P8's fast charger is)...and what the qualcomm quick charge 2.0 (and 3.0) spec can provide. Now i'm not saying the P9 is a qualcomm quick charge phone, it's not, but my QC2.0 and 3.0 car chargers certainly charge my phone quicker than the included mains charger! So i suspect that the car chargers are providing 9V2A to the phone.
Whether this means any 9V2A charger would do......I don't know

Qi Wireless charging problem

Hello!
i've bought Nillkin Disk Charger III which support fast charge (9V/1.7A max 10W) so does original Sony XZ2 charger and XZ2 itself. Sadly, when charging using Nillkin, XZ2 uses normal charging mode, not fast. 25% in hour. Only 400-500mA on wireless charger vs 2600mA on cable. With or without phone case, doesn't matter.
What can I do to charge it faster?

Bump.

Buy offical one by Sony

I use this one and all is fine. https://www.amazon.com/dp/B01KJL4XNY/?tag=flv-21&ascsubtag=6987aeb4-b272-4b5f-935b-f94acfec1a3d

Can you download Ampere app from the play store and run it while charging on this Anker pad. Let us know if this one can really charge the XZ2 beyond the standard 5w speed. Report the mah if it can exceed the 800mah standard qi rate. Remember, fast wireless charging at 9-10w should be around 1400 to 1500mah.
I have tried 7 different brands of fast 10w wireless chargers so far (but not an Anker yet). None of them can exceed 800mah on the XZ2. I wonder if the official Sony one can really do it at 1500mah.
So, please use Ampere and report back your results with the Anker, thank you!

I think this video can give you an idea of the Sony wch20 charging profile: https://youtu.be/BnasDqGFcFg close to 1500mah but not for a long time.

I too have a similar question. But it's about maximum allowed power for XZ2 wireless charging.
I just talked with Sony support and they too have no clue how XZ2 Qi wireless work. They told me better to buy (if at all) other brands' chargers with output NOT exceeding 9W, since it is the maximum output by the official Sony wireless charger.
But apparently some 3rd party brand reps told me that Sony uses Qi 3.0 and 10W chargers are completely fine. And all fast charger on Amazon output 10W with Qi 3.0 adapter.
So I am really confused whether those faster charger is safe for XZ2 at all.
'And it is very confusing that the Sony original adaptor has 3 working power: 5 V 2.7A DC, 9V 1.8 A DC, 12 V 1.35 A DC.

That's called Qualcomm Quick Charge.
While USB is specified for 5V QuickCharge 2.0 can use 5V, 9V and 12V (not used in phones).
QC 3.0 is even better as it has adaptive Voltage scaling from 4V to 9V theoretically.
Practically it's around 4.6 to 7.5V changing fluently during the charger process.
For normal cable powered charging the device itself decides how much amperage it wants to draw. The wall charger can only set an upper limit like 'only has 1.5A at 5V'
As wireless charging sends out power I think there is a communication between sender and receiver which handles the power output. Haven't really read much about that though.

Hi,
Has anyone found a charger other than the official one that will charge at more than 5W? I bought a 10W wireless charger from Amazon and it only charges at 5V 1A whereas the same charger charges a friends iPhone at 7.55V 1A. Has Sony built something into the phone/software that only enables 9W charging with the official dock?
Thanks

Not so far. Got a Seneo fast wireless charger and some other brand I can't remember the name of; both tried with multiple QC charging packs I have lying around (and even Sony's brick supplied with the phone). According to AccuBattery, the XZ2 never pulls more than around 700 mAh, while my Lumia 950 XL hovers around 1700.
I'm thinking you're right, there is something special the XZ2 looks for in their WCH20 wireless charger unfortunately. I've tried turning Battery Care on and off too but that hasn't changed anything as far as raising the current draw.
I really have to try it when the battery is below 20% though to be a fair test.

Update: So I bought an Anker Powerwave wireless charger and QC3.0 adapter which Anker claim supports 10W charging on the XZ2. I have tested it and it charges at 7.45V at 1.2 Amps so not quite 10W but it charges from 0 to 100% in 2 hours 50 minutes which is much better than the first wireless charger i bought which took over 4 hours 30 minutes at 5W. Hope this helps.

actually, 7.45v at 1.2A is 9 watts. Which is reportedly the XZ2's peak draw.
A couple questions:
What did you use to check the charging stats? (I'm using AccuBattery currently). I don't think the latest Xperia phones have any fast charge indications like some other OEM's do.
Was the 7.45V/1.2 amps reading at 0% battery?
Was Battery Care enabled?
Did you happen to check the charge levels at various times during the 2h 50m and see if it fluctuated?
I'm using an Anker QC 3.0 charger with my Seneo which charges great over USB, so I don't think my problem is the charger. I'm going to let mine go to below 20% and try again.

I use accurate battery on every device I maintain.
At least to give an alert, if 80% battery capacity is reached during charging.

Sorry, yes I know its almost 9W. I was just making the point that it didn't reach the 10W Anker claim it can.
I use an inline USB amp meter...
The 7.45V 1.2 amps was from 0% to 70% after that it was 7.45v 1.0 amp until 100%
The 1.2 amps could only be achieved by careful positioning on the pad, if it was slightly to the left/right it would drop to 1.0 amp.
Battery care was disabled.
Thanks

I think the 9W cap is Sony, not the Anker.
I'm going to send back my Seneo, obviously something is not working right with the XZ2 regards fast charging. Tried it with several different QC chargers, moving it around on the pad etc..
Thanks!

No problem
I would love to test out the WCH20 but in the UK Sony want £129. Have found it on Amazon for £70 but it's still silly money for a charging dock!
If you're considering the Anker Powerwave, it is very good. My only gripe is even though it stops charging once the phone reaches 100%, the cooling fan keeps running until you remove the phone from the pad which seems like an oversight.
Cheers.

Hello!
i've bought Nillkin Disk Charger III which support fast charge (9V/1.7A max 10W) so does original Sony XZ2 charger and XZ2 itself. Sadly, when charging using Nillkin, XZ2 uses normal charging mode, not fast. 25% in hour. Only 400-500mA on wireless charger vs 2600mA on cable. With or without phone case, doesn't matter.
What can I do to charge it faster?

I have the Nilkin charging stand for my XZ2 Premium and I am more than happy, it takes about 2hrs to go from 50% to full charge, it will never be as fast as wired charging, and the battery life on the Premium is great, I can easily get 2 days but would rarely need that.

Sony WCH20 can do 1700 mAh but only to 50% of battery charge. After that it is slower 1400 mAh and that again slower.

Guess I'll have to try the Anker Powerwave (which one did you get if I may ask?). I tried yet another brand, which again, fast charges my old Lumia 950 XL just fine around 1600 mAh, but the XZ2 refuses to go beyond ~700 mAh. Wondering if it's my phone or the XZ2's coil is just in a weird spot.
I'll have to spring for an inline USB meter. maybe it'll help me find the "sweet spot."
