Possible Trick to get Quick Charge on Z2 international varient

I have been searching for Z2 quick charging, and find out that z2 have quick charging enabled only on Japanese model ( SO-03F) (and it have a 32 gb internal memory). And qualicom itself says that z2 support quick charge 2.0. ( well dont get confused over the terms quick charge and fast charge ( fast charging = 5v @ amps over 1 amp, possibly [email protected] 1.5 - 2 Amp and Quick charge 2.0 = 9/12 v at 1.5- 2amp, higher voltages).
I have tried with note 4 quick charger on z2 6503, but it charges in normal mode. So sony have possibly dissabled quick charge 2 on other varients of Z2 (why sony... Why!!!). But since hardwares of Japanese model and other region's models are possibly same ( except radio and memory???, or are they locked, since radio unlocking can be done in all sony phones), i think that the same quick charge chip is used in international models and possibly locked down.with software, may be we can enable it via some tricks???
My idea is:-
1) cross flash SO-03F FIRMWARE ON INTERNATIONAL MODEL
2) dissassemble kernal and other hardware drivers along with scripts ( cross matching them) and find out where the code is hidden/dissabled and copy that to use with international models.
So any possible idea, thoughts,disaster report is welcome.
I have 90% confidence in this, i need help and reports from kernel developers, can you guys just cross check the kernel of SO-03F with international varient like 6503?
Hope we can find it out since we have made great things like 4k and slow-motion port for z1, which is a different phone, but in this case 99% of hardware is same.
So pls help to dig this out..

I'm quite sure the QuickCharge is enabled somewhere in the kernel.

May be... But we dont know yet...

Basically, if you turn off a QC2.0 device and plug in the charger it still is going to charge at full speed. This means it has to be the kernel. Unless it uses some external drivers from the system, but I don't think that's the case here.

So u saying that quick charge still works when phone is off?

Well, I don't have a Z3 or a Z2 variant to test it, but I'm quite sure it does.

Any previous experience with any quick charge devices? Welll so we need the help of a kernel developer.. Seriously i have very lil knowledge about kernel development.. But i will look for sources to compare..

Well, I'll try to find out how it works after my exams

thank you mate. well i would love to get attention of all developers to this thread.

@AndroPlus would be most qualified guy for the job

Thank you for this thread, i would like to add something
The official indian website of Sony lists a fast charging mobile charger compatible for the Z2 http://www.sonymobile.com/in/products/accessories/quick-charger-ep881/
& i bought it, but it doesn't do anything as it claims.
Now i may be a little skeptical but i think that as i bought my device from China through ebay, maybe thats why im missing this feature.
P.S. The power output of the charger is 12W which makes it total legit as a quickcharger

Check the volatge and amp description of that charger, if it is 5 v @ some "x" amp, then its just normal charger with high capacy. Not quick charge 2.0, but if its 9 or 12 v its a quick charger.

EP881 is not UCH10 is. Link: http://www.sonymobile.com/global-en/products/accessories/quick-charger-uch10/

QuickCharge is enabled by default, so no tricks with kernel needed.
But, as I found out reading on xda, you also need compatible CABLE to be able to use quick charging. Apparently the standard data cables cannot push enough current through them. The compatible cable (which ships with some of the newer devices) is labeled as EC 802. And as far as I understood any cable which has those cylinders behind both ports on the cable, can do the job.

Uhm, what kind of cylinders?
If you mean those 1.5cm in diameter plastic coated things on both ends of the cable after the connector, thats simply Lead to reduce electromagnetic interference or such a thing. I have a cable with those USB 1.1 that's about 8-12 years old.

Guys pls dont try to suggest things if u dont know what are you talking about.. I did say its quick charge 2. Not fast charging or rapid charging or lighting charing or what ever... Quick charging is a new method adopeted by qualicom.. Its not about amp ratings.. Its a method through which battery is charged with more watts/hr. And its the voltage increase that does the trick, not current. I have said the difference in op post...!!!! I wish some development should be happen, not just talking..

Well well well..... Is it physically even possible for the non Japanese version? Maybe they've put another VRM on the PCB on the SO-03 revision which can handle 9v, and the international version does have an older chip?

I forgot to say any newer cable, surely not those 10y old. Try to do a research on quick charging, I really don't know much about it, but I have found some posts where people tested different cables with aftermarket quick chargers (those approved by Qualcomm) and confirmed that not all of them will work, specifically EC802 does, bot not 801 and 803 (which I have).

I know the basic difference, I have just shared that I have found info about cable compatibility, not just the charger itself. No need to be upset about it, I was just trying to help, dear God.

If any one of the members want to know the basics of quick charging and similar technology for our devices, read this article by androidpolice
http://www.androidpolice.com/2015/0...-need-to-know-about-charging-your-smartphone/

Well one thing that is missed in the artcle... I will explain.
Normaly most rapid chargers/fast chargers ( not quick charger 2.0) like my sony oem Ep 880 which came bundled with z2( rated [email protected] = 7.5 w) and samsung model Eta-u90IWE which i use on my z2 normally ( rated [email protected] = 10 w) can charge z2 fastly ( using a belkin 2.5 mts usb cable) but neither is quick charger 2.0.
There are other oem chargers which are rated at 3amps or even 4.5 amps like asus transformer pad charger ( ie 5v at 3amp=15w or 5v at 4.5amp= 22.5w) but then too those are not quick chargers 2.0, since that article says that anything above 15(or18) watts is a quick charger 2.0, there will be a chance of miss conception.
Let me clear it, quick charging 2.0 chargers charge phone with higher voltage and below or equall to 2amps, thats how the wattage rating increses ( 9v @2 amps= 18 w 12v @2 amp = 24w) so be sure to check the volatge before choosing a quick charger. Any currents above 1.5 will do the trick if u have 9/12 v chager.

Z5 fast charging

Hi.
I've came from a note 4 with fast charging to a z5p with supposed fast charging. The difference in battery capacity isn't too much. However, the z5 charges so much slower. I've tried multiple quick charge certified wall plugs and a quick charge 2.0 powerbank, the official wire and other wires as well as my old note charger plus wire.
Is this a fault in the firmware or a fault with the phone?
I get the results with the note what I expect. However with the z5 it feels like going back in time with a 'normal charger'

Mines been okay, I even have an Aukey fast charger and it's at the same pace.

I've noticed that quick charging isn't as fast too...I have three quick chargers and all three have worked great for phones like the S6, Nexus 6 and even the Zenfone 2.....I'm going to run my phone down to less than 5% and then watch to see how long it takes to get to 100%. It could be due to the Z5 Premium having a very big battery (3450mah I believe)....My Nexus 6 seems to be the fastest to charge...I have seen it literally go from 10% to 65% in 20 minutes.

I'll try my luck this week and report back for you guys.
As an aside though, I've typically avoided using QC2.0 unless I'm super desperate. That kind of heat and power going to the battery just screams "device killer" to me. I've used it on a Nexus 6, HTC One M9, and a Z3 - same heat issues across the board. I think I'll be relying on my faithful Aukey's standard USB ports. (Aukey PA-T1 54W 5 Port USB charger, fwiw)

Please let us know. So far the assumed quick charge 2.0 is a let down. Be back off to Samsung if not sorted

Not OP but been using the Z5P for the past few days... QC 2.0 is pretty fast, but not as fast as I expected it to be. As far as heat is concerned, I've had no issues from it overheating while charging.

Sony is notoriously conservative when it comes to battery charging. For example the Z3 only used QC2.0 to allow more flexibility in charger cabling - battery current was limited to only 1.5A. With a normal charger you could only hit this if the screen was off with an extremely short cable, with QC2.0 you could hit it even with a thin (more flexible) MicroUSB cable with a right-angle connector that would cripple charging on most phones.

Probe not noticing the results as well with always being on the phone

I bought this one from aukey for €15,- and in dollars like $20

I purchased the aukey quick charge 2.0 charger. It operates fine with my old note 4. So I see this as Sony issue

The device is most definitely using QC2.0 for power input - my Powergen wall charger turns green when the Z5P is plugged in.
Edit: If I'm reading the kernel source correctly, charge current is 2.3A with no step charging. https://github.com/sonyxperiadev/ke...com/msm8994-kitakami_satsuki_common.dtsi#L986 - No way will you hit that without QC2.0 except MAYBE if the screen is off and your USB cable is 3 inches long.
Z5 non-premium is 2.1A with no step charging, Z5C is 2.1A below 65% and 1.5A above 65%

my z5p came with a 2.0 UCH-10 charger from sony http://blog.clove.co.uk/2015/06/12/sony-uch10-quick-charger-coming-soon/

Thanks for the input. Any idea about the drop after 65%?

That only applies to the Z5 Compact. Smaller battery makes it easier to stress it. In general, rapid-charging a battery is far more stressful above 60-65% charge than it is below this, which is why so many companies specified "time to 60%" specs - because nearly all of them drop the current past 65%. The Z5P seems to be an exception - it has a lower charge rate (compared to the battery size) below 65%, but maintains this charge rate up to the CC/CV transition point (usually 80-85%).
Rapid charging past the CC/CV transition point cannot be done safely.

Is QuickCharge 2.0 working with magnetic cable?

Hello friends,
I've bought an Aukey QuickCharge 2.0 (Qualcomm) Car Power Adapter and want to use it with a magnetic cable (original Sony).
Someone know, is this a good combination / is this working?

I have an Aukey QuickCharge 2.0 wall plug. When using a USB cable it appears to charge quicker than when using a magnetic cable (after market). The USB cable is higher gauge than the magnetic cable so that could be why. However, I do not think QuickCharge works on the magnetic connector. That being said the Aukey QuickCharge 2.0 does have a higher current and can charge non QuickCharge devices faster than the regular adapter. So I think you will notice it charge faster using the Aukey QuickCharge adapter and the magnetic cable versus a regular adapter, but not as fast as using a USB cable with the Aukey QuickCharge adapter.

yes, works very well for me. I use the same and it goes from under 10% to over 50% in 40 minutes. I slows down a bit after that, and the closer to 100% it gets the slower the charge.
You should be able to get from 0% to 100% in a little over two hours. The reason I bought a Q 2.0 charger is that it negotiates with the phone to get the best rate of charge, so even though it's super fast charging, the phone doesn't even get warm. It worries me when I plug my phone in somewhere I I feel it getting hot, it can't be good for the battery.

I recently bought a Quick Charge 2.0 adapter and can tell you that it made no difference to my charging times. Whether it's the standard charger that came with the Z3C, the Quick Charge 2.0 adapter, usb charging, or magnetic charger, my phone charges at about 1% per minute with any of those combinations.
Supposedly QC2.0 can charge up to 60% in 30 mins, or 2% per minute, i.e. twice as fast as a regular charger, but I didn't get close to that. I had a friend test my QC2.0 adapter on his LG G4 and it charged from 0 to 75% in 30 mins, so I'm guessing QC2.0 isn't active or doesn't work on the Z3C, at least on mine anyway.

Thanks, you have solved my question aahahha

With the magnetic does not exactly work.

I thought that for Quickcharge the data lines of the USB cable have to be used, because the CPU needs to communicate with the power supply for switching to QC 2.0. Right or wrong?!
And the magnetic cable doesn't provide any data lines

i just replace my z3 compact battery it turns on but won't charge... how i can made the unit charge again please help... the battery is ok...

chargers

So I've had a USB c for a while and now I need a second charger for this phone? Any recommendations that will work with the fast charge? I have a quick charge base already that I used with my LG, will any micro USB cable work with it? Pardon my ignorance

Anker and Aukey are my goto for everything charging related

Most cables work except for the ones that you run into occasionally that won't charge any device properly.

So my Qualcomm 2\3.0 adapter doesn't seem to quick charge this device. Any idea where to get an OEM Moto adapter that came with the phone? Or an aftermarket one that works with the turbo charge

Buy a moto g3 turbo(merlin) charger that works perfect with moto g5+

would you specifiy the product?
The Anker PowerPort+1 18W (QC 3.0, one Port) doesn't quick charge my G5 plus. Stays in 5 V + 1.5 A mode (which is only 7.5 W), instead of 12 V + 1.5 A (which is 18 W and does the exact same harm to the battery due to the same current... - so in this case I'd prefer to use one that uses quick charge).

i got it a long time ago so i am not sure but it looks like this

I hope you don't mind me asking, but: Does this mean you've been testing it with a voltage and current USB monitor (power monitor) that it really charges with a voltage of something like 9-12 V(DC) and a current of 1-1.5 A(DC) and you've also seen the "turbo charge" within the G5 Plus display or does it just "work" in the sense of "it is charging, but not sure at which power" ?

Can I use another charger to prevent the P2 from fast charging?

Hi.
I originally came from a vibe P1 which is now my gf's. One issue I had with the P1 is it gets noticeably hot during charging, which I take is not so good for the battery. Can I use a lower rated charger and let the P2 charge at normal speed to prolong the lifetime of this phone? I currently have a 2A charger from a Xiaomi RN4, I do not know how much current is the P2 charger rated. I'd appreciate all inputs.
Thanks.

you can indeed . of course it will take a bit longer to charge the phone . I use an old Samsung charger - 0.5A for charging phone and tablet .

Any chance that you know the Watt rate of the stock charger that comes with the phone? I have a 5V 2A charger which I guess is 10W. I have no idea how much W is Quick Charge 3.0 rated for but I'd like to have one quick charger to bring with me on trips and a normal one to charge it at home in normal situations.

I received the phone today. I think the charger that comes with the phone is some kind of quick charger because it is rated for different voltages, about the same current. So the verdict is the p2 has quick charging, just not Qualcomm's quick charge 3.0?
