Possible Trick to get Quick Charge on Z2 international varient - Sony Cross-Device Development Themes and Apps

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.

Fast Chargers

Will using a fast charger hurt the phone?
I have been using my note edge charger but will it cause issues?
Always only use the charger that comes with the phone, other chargers may cause issues (damage battery, damage the phones charging port, etc.). its not gonna be really fatal if the charger is fine, but its reccomended to only use the charger what came with the device.

Sony xperia z5 premium is totally Qualcomm fast charge 2 capable.
I use my note 4 fast adaptive charger without any issues and it is fast charing as hell. This is because the phone support Qualcomm quick charge (which is a open standard from Qualcomm and Samsung use the same).
Even if you want you can't damage your battery because a controller inside the phone or the battery is controlling the charge, checking multiple parameters to avoid battery explosion.
It is simple - you can use even 5A charger, but the controller inside the phone will allow only safe charge rates.
So at the end, Yes you can use your note edge charger without any issues!

Anyone know what the fastest possible charging time from about 10% to fully charged would be? And with what charger?
-xirt0n
Mine came with the UCH10 charger and am using my short Sony usb cable that came with my headset (EC300). I went from 4% to 100% in 1 hour and 35 mins. I also tested with the Tronsmart quick charge 2.0. It went from 6% to 100% in 57 mins. Both chargers support the 5v/9v/12v output. Does anyone have a qc2.0 20v charger? I wonder if it will be faster?

what is your favorite fast charger for the le max 2?

Hello guys,
as the title already says I'd like to know what is your favorite charger for the Le Max 2?
Do you guys all think that the OEM charger from LeEco is the best considering the charging speed or did you find even faster solutions?
Curious for your answers!
ANY qc 3.0 charger, i suppose

Dear collegue. I am yet waiting for my X822. Maybe you could give me some information how long does it take you to fully charge your X820 from 0% and are you satisfied?
regards Olek
If the phone is off, I need about 1h30min. to full charge it when it is not in quick charge. First time I used QC and the phone heated up so that's why I know use the normall method.
For me it takes 1h20min with phone on and the capacity of the battery is correct measured with small USB tool. Fast charging is sometimes 8V and 2.5 A.
Wysłane z mojego Le X822 przy użyciu Tapatalka
got the X822 aka the grey version in transit, couldnt resist it at 222US, ewen thow im not in the market for new mobile, allready pretty satified with the p8max that i like a lot and that dont got any quickcharge tech at all afaik, other then just plain 1.9amp charge cycle., according to my YZXstudio1270 meter, but the 4300mah takes here around 2.15 hour to fill, but slowing down massive the last 5 to 10% like the norm.
that tempo is fine by me, but have also purchased the Vinsic P3 terminator with QC and type C in & out. intended for the X822. seemed reasonable at 28US and with product-specs that shouldnt be to fare for real-world according to reviews.
JUst wondering if you can trick QC3.0 trigger on other devices, got an relative old usb trigger for QC, but no QC phones or at least chargers to check if 9v and 12v can be optainable and be used for ones 12v coreM tablet, just like that and push of an button..
anyway certainly looking forward for my first entry into my first QC device Lemax2 X822 and not least typeC.. LeMax2 lookzs wicked in grey. .:good:

You are sure that the quick charge is actually off.?
when checking on mine X822 and turning the knob in setting < battery < quick charge' to not active.
it still display the same voltage and above +6v to around 9v dynamic.. (its the same when the phone is off)
its like the "quick charge off function" doesnt do anything at all. (am on stock X822 assume its 16s EUI'build)
if you got an usb-meter, try to measure if the voltage actually stays around usb 5v level when turning the quick charge off. (mine it doesnt on stock QC charger)

I'd like a charger for night-time charging. Does anyone know if there are ill effects by leaving your phone on quick charge for extended periods and doing so daily?
And would one risk damaging this phone by using any other 'regular' charger?
Any charger should be safe, just make sure the cable you use has Pullup resistor of 56kΩ, without that 56k chip all kinds of stuff can go wrong. usb A to usb C is a really bad setup and you'll need that chip for protection..
Thanks castuis. Best thing I learned today This (and this thread w/charger links) is good to have.
So Which charger and cable are the best for the price? Original or something else. And where to buy with shiping to EU?

This is by far the best way to buy cables and chargers. You will learn way more than you ever wanted about USB accessories.
I bought the multi pack of Orzly cables , they are the best, relatively cheap... Sturdy.... And won't burn up your phone/house.

Right, but those links mostly focus on USB C standard, not QuickCharge 3.0, which I believe technically violates USB C standards. I'd still suggest sticking to cables confirmed to have the correct pull-up resistor, and if you want to use USB power delivery rather than QuickCharge technology you can also stick to chargers and power banks from that list. I think QuickCharge 2.0/3.0 will still charge faster than USB power delivery though, in which you probably won't find them on that list.
In any case, I bought an 1 port Aukey QuickCharge 3.0 car charger and it seems to work well to charge up to 4 amps. I also bought an Aukey 10000 mAh QuickCharge 2.0 power bank, and it too seems to charge my phone at up to 4 amps. Both were bought from Amazon Canada. I use them either with the cable that came with my phone or good micro USB cables and Tronsmart Micro USB to USB C adapters (which have the appropriate pull-up resistor.)

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

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 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" ?

Correct, but it supports QC4.0 (as confirmed by others). May be two possible reasons 1) Bad marketing 2) The included charger is only QC3.0 (Why LG, why...its you flagship phone, show some respect and love)
It says

Yeah the 845 supports it but i dont think LG has enabled it in firmware.
Im just excited we have fast wireless charging thats useable.
Kind of like bands, the radio will do them all but most are firmware specific.

before buy qc 4.0 charger i think the first step is create a mod that enable quickcharge when screen is on and possibility of increase max charging current to 3 amp
notice that when screen is on max current is around 1A and when is off is around 2.2A
so i think is useless buy an expensive charger when the firmware is limited to these values

Exactly, we need a custom kernel to have the charging amperes to be changed manually which is really cool. If we have a really cool custom kernel, the CPU governors should preset customisable governors (for smooth performance) and for the charge values, just look for a 3A charger, with the Kernel Adiutor change the values. Meaning the benefits of rooting gives us the complete freedom of our Android! If a 4A charger is detected by the kernel manager app, the charge values should show as "upto 4A even with the screen on! Then no need to be jealous of Dash Charging of One Plus!

Quick Charge 4.0 doesn't bump currents to 3A, it's not working that way. It bumps voltages to 20V instead

Yes, and no, i think the only one "problem" (or protection?) is the limit at 1 amp when the screen is unlocked, 20 volt i think isn't so useful if we use a good usb cable

But, even Samsung said and officially stated that after Note 7 fiasco they made same limit of 1A when screen is unlocked to prevent fast battery degrading. Samsung knows better then XDA uses, I think

Why? So G7 could pave the ways of Galaxy Note 7 and if not burn in flames then at least loose 50% of battery capacity in half a year? Sorry I'm not enlisting to shoot myself in the foot and throw expensive $700 phone in half a year to garbage can just because
Quick Charge 4.0 doesn't bump currents to 3A, it's not working that way. It bumps voltages to 20V instead

It's not 20 volts. That's way too much for a battery. It's actually 9v + 2 amps. 20v it's mostly for Tables i think.

9 Volts isn't even Quick Charge 3.0, it's legacy QC 2.0.
QC 3.0 & 4.0 compatible phones can get charged from 20V, 12V, 9V and 5V
This is the one I use:

But if I plan ahead, I try not to use it very often. It works well, it's just that the long-term health of my battery benefits from slower charging.

What is Superfast Charging actually?

So what is actually superfast charging? Is it just Samsung's term for USB-PD? Does our phone support USB-PD? I'm still relatively new to this charging protocol.. What's PDO and PPS?
Hello
This "Superfast Charging" is very similar to Qualcomm's Quick Charge technology but is somewhat more proprietary. Remember when Samsung launched 15W fast charging with the Galaxy S6? This is basically the same kind of thing, except instead of being only 15W, this is 25W. For comparison, a regular laptop charger from the last decade or so can support anywhere from 40W to 120W(Possibly more). Apple's newest MacBook Pro comes with a 96W charger. It supports USB PD (power delivery). However, USB PD has a very specific standard and is only supported over USB C cables, and has to be 60W or more. If you were to plug a USB PD cable into a device which only supports up to 25W, then the device will only draw up to 25W. The reason laptops and some devices can charge faster than others is because of the chemistry and thermal management they use. Remember, a hot Lithium Ion or Polymer battery is a very bad thing, and the faster a battery charges, the more heat it produces because of internal resistance. Though you may hear about something like Wh (watt-hours), this is very different to W (watts), since Wh is a unit to measure how much energy a cell can store, while W are generally used to measure HOW FAST a cell can charge. PPS is an acronym for Programmable Power Supply, this basically means that the power supply (or charger) is able to change the amount of current it supplies, so that it doesn't fry the circuitry of the device if it cant handle it. PDO is an acronym for Power Data Object. GSMArena has a good article about this.here
I hope I answered your question, oh and sorry I got carried away with the length , I find these kinds of thing quite interesting!

Thank you for the detailed explanation, now for my real question : can you plug a USB hub with multiple USB-A ports and a USB-C port and charge to this device through said port using any charger?

No, that's not true. USB-PD is flexible in it's power delivery and was designed to be one standard for all usb devices.,

I tried and apparently it is possible. But the charging would be standard charging.

Please get carried away some more! I love this kinda great info sharing, and it's the reason xda exists.
Thanks

Apologies for that, I think I got messed up with another fact I read up somewhere?

This will mostly depend on the device itself, as well as the hub you may be using. This is because we are not certain what the manufacturer intended the product for. If you have a hub like the one you described, give it a go. It should work but if it doesn't, the worst that can happen is it doesn't do anything. No biggie!
Oh and also, just make sure that the charger you'll use is powerful enough, just to make sure that your host device will actually charge at a reasonable speed.
