My thoughts is that.

1. QC 2.0 is not fully supported by Z3 compact, or at least by the latest generic firmware

2. Maybe it will come a future FW update that will support this

3. It could be that the hardware (battery?) does not support QC 2.0 and therefore Sony didn't implement it.

4. It could be that other revisions of Z3 has slightly different hardware and some has QC 2.0 capability and others do not.

so many questions, so few answers :(
[Xperia Z3 Compact Accessories] mtilson:
I don't have hard data, but I recent bought (and have since returned!) a Power Partners PEAW30-12-USB QC 2.0 charger and saw NO decrease in charge time compared to the stock Sony charger. Very disappointing. No potential of QC 2.0 functionality thru the magnetic charger sucks anyway.
[Xperia Z3 Compact Accessories] willumpie82:
I got myself a QC 2.0 from amazo (Aukey) which is Qualcom certified.

charging mij Z3Cwith the QC2 goes just as fast as my 5port 40W charge station (2A / port) @ 1355mA

when plugged my z3 Tablet Compact into the QC2 charger it charges upto 2677mA !

so short to say, Z3 compact is not QC2 ready

Z3 Tablet compact is

hopefully they enable this with some FW upgrade

For your information EP881 is not a QC 2.0 charger.

Done some testing and the Z3 Compact pulls 9v , 1A from the QC 2.0 charger. According to voltage the handshake between the QC 2.0 charger and the Z3 Compact seems to be working as the phone pulls 9v and not 5v from the QC 2.0 charger.

I would love to see it charge at 9v, 2A which is the true QC 2.0 speed.

Sony can't explain why it's only pulling 9v, 1A. Hopefully we will get an answer within the next months or so :)
[Xperia Z3 Compact Accessories] monx®:
How to know EP881 is not QC2.0. Any source i can refer? the stock shipped charger is quick eno for me just dont hv time todo full test yet.

I also hv Note Edge shipped Quick chager which is QC2.0 according to verizonwireless site for instance. And it does really quick charging the Edge.

Im going to test all these 3 chargers (including shipped charger) on my Z3 Dual. I need real good trustworthy app to check actual current.

There's different ways to check if your charger is a Quickcharge 2.0 charger.

1. Look at the charger, somehwere on the charger it will be printed "QC 2.0" "quickcharge 2.0" or similar

2. The output voltage should be 5v, 9v and 12v. If it's only printed 5v 1,5A on the charger, it's not a QC 2.0 Charger

There is no great app to measure current, the best way is to buy a external usb current/voltage meter.

Look at the attached picture.

Hi senz007

Just got a new Z3 compact so I am following this thread with interest.

The white USB multimeter you are showing in the previous post is the only one that looks like a finished product. However it seems to be specified only up to 7V. Have you had any issues using this with QC2 at 9V? Do you think it is ok to use this up to 9V or should I go for one of the ugly ones that are specified to higher voltages?

Thanks
[Xperia Z3 Compact Accessories] senz007:
Sorry m8, I didn't check the volt-range on the meter. Anyway, me myself does not own a usb-voltmeter. I borrowed one from a friend (not the in the picture).

The picture is taken from another thread about Sony Z3 Compact Charging.

I think you will be good with any of them within 3-10v range.

but note edge quick charger (shipped) doesnt mention any QC2.0 even not on Qcom site & only printed as quick charger with current spec same like normal samsung 2A charger. So i guess labeling doesnt matter. just need smth to check the current output. At least note edge will notify if quickcharger is plugged in.

If you mean the Samsung Adaptive Fast Charger, it is a Samsung developed charger and has nothing to do with Qualcomm Quickcharge 2.0

The Samsung Adaptive Fast Charger outputs 5V, 2A or 9v, 1.67A. Charging a compatible Samsung device would be aprox 30% faster compared to the standard 5v, 2A charge.

I you use this charger together with your Sony Z3 Compact I think the phone will pull about 1500mA from the charger, (basicly the same as the stock charger).

With the android app Battery Monitor you can easily view how much mA the phone pulls from the charger. If you see it pulling about 1800mA it should be pulling 9V 1A.
[Xperia Z3 Compact Accessories] monx®:
now i und. AFC & QC2.0 are diff.

EP880 & EP881 are same & not QC2.0.

luckily i bought EP881 using redeemed credit card reward :D

now looking for smallest size QC2.0 certified adapter :o
[Xperia Z3 Compact Accessories] Dreamslacker:
Based on your results, the phone actually supports QC 2.0.

That is to say, if the phone can negotiate a charge voltage higher than 5v with a QC 2.0 charger, then QC 2.0 is enabled and working.

The reason a Z3C cannot charge faster is because of technological limitations due to the battery size.

A Li-Ion (or Li-Po for that matter) isn't meant to be charged above 1C (C being the capacity of the cells), in most cases the charge will initiate at less than 1C to maximize battery lifespan.

For the Z3C, the battery is a 2.6AH (2600mAH) single cell unit. That means that having a 4.2V charge voltage (common for a 3.7V nominal Li-Ion), the charging current cannot exceed 2.6A -> Total charging power of 4.2V * 2.6A = 10.92W.

Most rapid Li-Ion charging circuits will normally kick off at ~0.8C (for Z3C, that is 0.8 * 2.6A = 2.08A) when the cell is at low capacity. With a 4.2v charge voltage, this means a charging power of approximately 8.74W.

A 9V, 1A charge implies 9W of charging power, which sounds about right after deducting power conversion losses.

Your main advantage of having QC 2.0 here isn't faster charging because the cell capacity is the limitation. It is the fact that you can get away with thinner and / or longer cables with higher resistance since the current draw is lower - which means less power losses due to resistance.

For comparison, a Z3 Tablet Compact comes with a 4.5AH cell (most likely 2 x 2250mAH cells in parallel). That allows for up to 3.6A charging current (0.8C) at 4.2V (~15.1W charge power). In this case, QC 2.0 can actually allow faster charging because it can deliver more power using QC 2.0 at higher voltages (9V/2A allows 18W charging power) than with regular 5V/2A (10W).
[Xperia Z3 Compact Accessories] senz007:
Great explanation, if it's a hardware restriction then there's nothing we can do about it.

I will not invest in a QC 2.0 charger at home since I can' t benefit from it.

Thank you,
[Xperia Z3 Compact Accessories] adamk7:
Is that a separate device that gives you that readout or an app? If the latter, which app?
[Xperia Z3 Compact Accessories] wooki:
It's an device. You can get them from ebay china for $10+ pretty useful but i don't think they're very accurate..
[Xperia Z3 Compact Accessories] nikolawei:
I suggest you buy a USB meter to detect the current and voltage during charging. And you should check if your charger is QC2.0 compatible first. Charger supports QC2.0 only if it has 9V capability. The charging voltage is near 9V when QC2.0 is actived. Z3c's stock adapter is not QC2.0 certificated as it merely has 5V output. As my test, z3c's QC2.0 is working with Samsung Note4‘ adapter via microusb port, voltage and current are up to 8.95V and 1.00A respectly. And they work in regular 5.22V 1.6A via magnetic cable. Sony's DK48 dock has 9V capability but I dont own no one so i cant test it.

Besides, I found that Note4's adapter could output more stable current than EP880.
[Xperia Z3 Compact Accessories] eranyanay:
So in conclusion, There is no Quick Charge at all ?

There's no point investing in Car/home QC2.0 charger?

I understand that the magnetic cable doesnt support it due to no data pins there, but does it charge in regular speed or slower than microUSB plugged with QC adapter?

Has anyone tested the new Sony UCH10 QC 2.0 charger (comes included with Z3+ in box) with Z3C?

It should be available separately too.

Product page: Quick Charger UCH10 - Specifications - Sony Xperia (Global UK English)
[Xperia Z3 Compact Accessories] techguyone:
I've ordered one, hasn't come yet though.
[Xperia Z3 Compact Accessories] RaXelliX:
Ok. Im thinking of getting it and it's not expensive or anything but there's little point in ordering it if it doesent charge faster than EP881. EP881 charges from 0 to 100 in approximately ~150 minutes when phone is off (give or take a few minutes).

Another question - is DK48 dock faster than EP881? Im guessing no so i wont get that either. Moving the flap every time is not too bothersome for me - i did that ~4 years with my Sony Ericsson.
[Xperia Z3 Compact Accessories] PuffDaddy_d:
You are correct - the Z3C does NOT have QC 2.0 enabled. Despite having a processor that is capable, Sony restricted the charging to less than QC 2.0 speeds. No matter what charger you use, you will never charge faster than what you've experienced.

As for the magnetic charger, it is slower than charging through USB, but the convenience and battery life make up for it.
[Xperia Z3 Compact Accessories] Dreamslacker:
Actually, it does have QC 2.0 enabled.

It is just that you will not see any advantage if you have a USB charger that will do >1.5A because the battery capacity limits the maximum charge rate on the Z3C.

This isn't even a cripple by Sony, it is simply what a current generation lithium cell can handle, short of placing a larger cell (or multiple units to that effect), you cannot go pass the limitations without any great risks (fire and explosion).
[Xperia Z3 Compact Accessories] PuffDaddy_d:
Thanks for the info, but regardless of the cause, our phones WILL NOT FULLY UTILIZE QC 2.0.

period

It sucks, but we need to make sure others dont go out and buy a $30 QC 2.0 charger, only to get the same results as a standard 2 amp charger.
[Xperia Z3 Compact Accessories] Dreamslacker:
Actually, that remains to be seen.

There are some restricted cases where a QC 2.0 charger would be better - mostly when longer, or thinner cables are used. The resistive losses would be lesser when utilizing QC 2.0 at 9v than with a 5V/2A charger.

My phone is currently in the service center and I won't be getting it back anytime soon (headed for a long vacation) but I'll be testing QC 2.0 when I do get the unit back.

I'm more curious as to whether the phone can benefit from QC 2.0 if the phone is seeing active use while charging. Depending on the way Sony chooses to implement the voltage conversion circuitry, it is possible that QC 2.0 will allow supplying enough power to drive the phone in active use while maximizing the charge rate on the battery.
[Xperia Z3 Compact Accessories] PuffDaddy_d:
Interesting... it looks like the Z3 does not support QC 2.0, but the Z3C does? Once you do your tests, please let us know what you find.

[Xperia Z3 Compact Accessories] Dreamslacker:
I suspect it's dependent on the variant.

The Z3 Compact does support QC 2.0 as senz007 has tested: http://xdaforums.com/z3-compact/acc...z3-compact-t2957849/post58960945#post58960945

I'll check in with my friends using the Z2, Z2 Tablet, Z3, Z3 Tablet Compact once I get back later in the month.

Due to the cost of the UCH10, I wouldn't recommend users buy it because they have resistive cables. Unless there is a need to charge other devices that can benefit directly from QC 2.0, buying a thicker, better quality cable would be cheaper.
[Xperia Z3 Compact Accessories] PuffDaddy_d:
His statement lends to your conclusion that the battery limits the amperage. At only 1 amp, the quick charge benefits are not realized. This unfortunately puts us back to where we started. This device does not charge at QC 2.0 speeds. :(
[Xperia Z3 Compact Accessories] Davisk8:
Using Aukey QuickCharger 2.0 and Magnector X2 adapter i get 1.7 ampere and from 0 to 100 in 1.40 hour :D
[Xperia Z3 Compact Accessories] PuffDaddy_d:
The math doesn't add up though. Your phone would have to charge at 1.7 amps for the entire time from 0 to 100% to get anywhere close to 1.4 hours. The current would automatically reduce to a slower speed once you reach 80 or 90%, meaning it would more than likely take 2+ hours to fully charged from 0%

But there is at least one article that explains that the z3c can utilize qc 2.0 but the z3 can't (excluding the Japanese variant)
[Xperia Z3 Compact Accessories] KUN1:
So in the end does our phone support quick charge or not?

Or did i buy 2 chargers for nothing? ^^

I have a Tenergy QC 2.0 charger and a Z3C. The green light signifying QC 2.0 speeds turned on when I'd charge when I was on 4.4, but hasn't come on since I flashed 5.1.1. It appears that Sony hasn't built in the QC 2.0 support into their Lollipop roms yet, imo.
[Xperia Z3 Compact Accessories] PuffDaddy_d:
Who knows, it shouldn't be this difficult to figure out. Sony does not advertise it as a feature, and some people have reported that using a quick charge didn't charge any faster than a normal 2A charger. I'm just not willing to spend $30 to test it myself. The battery life makes up for the slow charging.

On my DK48 Dock is written OUTPUT: DC5.0-9.0V 1.8A so tehnically it should support up to 9V 1.8A but again it doesn't mean that Z3 Compact can utilize that...

[Xperia Z3 Compact Accessories] PuffDaddy_d:
Yes, it will charge faster, but not as fast as QC2.0 is capable of.
[Xperia Z3 Compact Accessories] RaXelliX:
Ok here are my results with UCH10. Times are from 0% to 100%.

Stock EP880(1): ~150 minutes (~two and half hours so rougly as slow as iphone 6)

UCH10: ~130 minutes (~a little over two hours wich is as slow as oneplus 2 but faster than iphone 6)

Be aware that on UCH10 0% to 90% takes 90 minutes (roughly 1% per minute on UCH10 - less on EP881). 90% to 100% takes an extra ~40 minutes bringing total to little over two hours on UCH10.

Also: http://www.tomsguide.com/us/fastest-charging-phones,review-2995.html

Z3C is not included in there but my data shows it mirrors OnePlus 2 pretty closely with UCH10 and iphone 6 with EP881.

So is UCH10 worth it?

When looking at the improvement in charge time (20 minutes faster) and the fact that online (phone is on) charging is not faster than EP881 - the NO.

When looking at the price and considering that it costs about ~7-8% of the phone itself (assuming Z3C=400€/350$ & UCH10 30€/20$) and improves charge time by ~14% then MAYBE.

When looking at the future if you plan on getting other QC 2.0 devices then YES.

So there you have it. My numbers maybe look a little bad for UCH10 but that's because of 0 to 100% charge time. Normally you'd be better off plugging it in at 5-10% remaining charge and charging to 90%. This will take little more than an hour wich is half the time of full charge.
[Xperia Z3 Compact Accessories] PuffDaddy_d:
That's good info - thank you!

What I would like to know is does your UCH10 charge any faster than a typical 2A tablet charger? That will tell us if QC2.0 chargers are really worth the extra $ or not. My tablet's 2A USB charger charges at nearly 1% per minute at times, though I haven't timed it recently to confirm.
[Xperia Z3 Compact Accessories] RaXelliX:
I dont have a tablet charger to test but i do have a 2,1A charger with two ports (one 1A and the other 2,1A). UCH10 is faster than the 2,1A charger. Infact the 2,1A charger was a slow as the stock EP881 charger that is 1,5A.

That's the only way to get faster speeds with QC 2.0 charger. However it will still not achieve full QC 2.0 speeds and will hover around 1%/min mark (non QC 2.0 and QC 2.0 chargers when phone is turned on do about half of that - ~ 0,5%/min).

1) Worst case, find a backup program that you can download as a CAB right to your phone... do that first. Try www.freecabs.de

2) I assume you've done a soft reset? Try unloading all of your Today plugins, soft reset, and try again.

3) Try turning off USB Advanced Functionality on your MDA.

4) Try unplugging and re-seating the USB cable.

5) Try rebooting your computer. Try Active Sync with *nothing* else running, including exiting everything unnecessary in the system tray.

6) Try different versions of ActiveSync... for example, I have problems with the newest version, so I'm using the last beta quite happily.

There's other stuff beyond all that. Post back if it's still not working... I seriously doubt a hard reset will be necessary.
