[Q] Does "Quick Charger UCH10" support Z3 ?

Sony announced Quick Charger UCH10 for Z3+ that's works with Qualcomm quick charge 2.0 as you know
Did any one try it on Xperia Z3 ?? and what are the results ??

If it's QC2.0 compliant it should work, since other QC2.0 chargers work.

There's been a number of posts about quick charge only being enabled on Japan Z3 & Z3c variants. QC 2.0 is supposed to charge to 60% in 30 min, but I've seen VERY few people get anything more than 1% per min.

It's enabled, but Sony does not use it as aggressively as some devices with removable batteries. You won't see much improvement with the screen off and a GOOD 2.0A charger with a very short USB cable, but you'll see some. You'll see major improvements when running Google Maps Navigation in a car - many charger/cable combos can't even keep the battery steady, while a QC2.0 car charger will charge the device at a reasonable rate even through a long/thin (normally VERY poor for charging) USB cable.
Sony's charge rate cap is 1500 mA (0.5C) into the battery. With screen off and a high-quality charger, you'll hit this cap inconsistently (frequent drops to around 1.2A from the cap of 1.5). With a QC2 charger, you'll hit that cap consistently even with the screen on and a crappy USB cable.

Thanks for the info! But isn't 1.5A charging capacity closer to the old QC 1.0 standard that came out a couple years ago? In order to qualify as QC 2.0, shouldn't the charge rate be higher? Is this why Sony does not advertise quick charging on either of these phones?

1.5A into the battery, but don't forget that you need to power the device also.
Let's assume a battery with a voltage of 4.0 volts. Typical system power consumption when idle with the screen off and external power disconnected is 700-900 mA = about 3-3.5 watts. That's when sitting at the launcher doing nothing.
So now that we know the system power budget when screen on and idle, let's calculate how much power is needed to charge the device at full rate:
1.5A*4.0 volts = 6 watts. This goes up to around 6.5 watts at 4.35 volts
So the total power to run the system AND charge at 1.5A is 6 + 3.5 = 9.5 watts and this is with the system sitting at the launcher totally idle.
Also, typical switching regulators are only 80-90% efficient. Let's assume 90% here.
So we need 9.5/0.9 = 10.5 watts input
A 2.1A 5v power supply can only deliver 11 watts into the cable. Cables aren't ideal and have resistance, so you're going to lose power in the cable at 2.1A.
Try to do anything with the device and there is no longer system power budget to keep the battery charging at 1.5A. Also, see the above about cable losses? Every charger chipset I've seen backs off when vbus drops below 5.0-5.1 volts or so. The 2012 Nexus 7 dropped 200 mA for every 0.1 volt drop below 5.1 volts for example.
QC2.0 ups vbus to either 9 volts or 12 volts (9v in nearly all configurations I've seen, SHIELD Tablet is one exception). 9 volts at 2A = 18 watt power budget instead of 11. Also, for a given power delivery amount, there's less cable losses at 9 volts than at 5, and the system can tolerate much more input voltage drop.
Try running Google Maps Navigation with this USB cable - http://www.amazon.com/StarTech-com-Micro-USB-Cable-UUSBHAUB3RA/dp/B001AR4NC8/ - If you use any standard 5v charger, your battery will discharge because there just isn't enough power to even keep the screen/CPU/GPS fed. Use a QC2.0 charger and you'll see the battery actually charge at an acceptable rate.

Fast Charging "Homemade". What are the risks?

I lost my original Fast Charger in my school and now I'm without one. The problem is, that sometimes I need that great feature.
My question is, can I disassembly a random 9V charger and "adapt" a Micro-USB cable to it? Since the GS6 supports 9V I don't see a problem there. Or must I short some data pins in order to enable fast charging to not fry the device?

Why don't you just buy a new one?

I definitely think that's not a good idea. Buy a new one. If you are worried about Samsung charger price you can buy a cheaper charger that support Qualcomm 2.0 quickcharge, it's compatible.

I thought the whole thing was dynamic, that at lower battery levels it charges at different amperage than higher levels, and at a certain point it kicks over to 5V. It doesn't charge at 9V the whole time.
Sent from my SAMSUNG-SM-G920A using XDA Free mobile app

@quarlow is right, it's dynamic.
You should buy a new one, much more safe.

If I plug a normal 'old' 600mA 5V charger to it, it says that it will charge in 6 HOURS! I can't wait for that.
I have disassembled the charger, unsolded the Female USB plug and solded it to an 9V charger from an TP-Link Switch.
I plugged it in and the phone started charging. It says "Cable charging" instead of "Fast charging" and it stated 6 hours too. After that, I shorted the data pins and then the time reduced to 2 hours...
I also tried a 12V charger (1.5A), but it don't charged, nor maked any charging sound.
Now I concluded two things:
1. Samsung S6 phones are very robust with charger voltages :silly:
2. It isn't that easy to make a fast charger.
I hope I have saved some questions now

Thanks for all the replies, but now I haven't money to buy one. Where I live, they are really expensive!
Oh, aaand, I don't know if it's a good idea to charge at 9V the whole time, because when it reaches 100%, I hear constantly the charging sound.

Looking at a Samsung Travel Adapter change...
https://www.dropbox.com/s/54xt2u315nn1tkt/2015-09-27 14.04.18-1.jpg?dl=0
Output is: 9v at 1.67A, or 5v at 2.0A. It's listed as an adaptive charger.

Thanks, I will search for an 9V charger that has this amperage.
Btw, some chargers have adaptive 12V output.... Is that QuickCharge 3.0?

A normal Samsung or LG charger of 1.8A/2A output still charge my S6 in about 1.5 hours. Get one from a relative or friend or buy one if the S6 charger is too costly

the factory charger got in fire sometimes i don know abt home-made chargers... take care dude

You gotta be kidding. Spend $10 and get a QuickCharge 2.0 adapter.
Don't risk it. Samsung Fast Charge is the same thing as Qualcomm Quick Charge. It's Qualcomm's technology, licensed with no loyalty fee.
QuickCharge 2.0 uses the data pins to negotiate the charge voltage with your power adapter. Otherwise it just uses 5V.
I see on my S6 it stays at 9V all the time. The phone pulls the current it needs, so you don't have to try to match that current on the power adapter side. Just make sure it's at least 1.6A, preferably 2A. I never saw my S6 pulling 2A at 5V or 9V.

I'd imagen as this a form for devs . And this guy is trying to create somthing . The devs would be a bit more yaknow . Creative. First off
The guy is trying to make the adaptive charger .give him a bit of credit . I'm currently making a portable charger and I want it to use samsung fast charge
I'm using 18650 battery's 4.2 volts fully charged 3.7 volts give or take when they sag.
So if there is anyone with half a brain out there. How do you get the 9v (8.4) amp to make it a fast charger ( under one and a half hours. ) I'll worry about building the switch to the 5 volts after ( 4.2)
Is it loop the pins . Pin to earth pin to positive loop pins to negative ) the information isn't out there so surely some one has the information. ( just FYI the sgs6 is perfectly capable of being charged at 9 volts. The battery is a nine volt according to the build information explains why charging with any other charger takes 6 hours. .
Also to the op if you did indeed have a similar idea to me just tell erm straight I wanna mess about with low current and voltage dc haha. ( also I tried 18 volts samsung phones do no alow the charge over 9volts so it cannot hurt you're phone

Mi 4C Charging Current (simple test)

I have found Mi 4C's charging current quite bizarre, more so than what was shown in: http://forum.xda-developers.com/mi-4c/general/xiaomi-mi-4c-charging-analysis-part-1-t3209028
I don't have fancy equipment so I just downloaded the Ampere app to test the charging current. While the app is not meant to be an accurate measure of the current, I find its result quite consistent with the charging time that I obtain. (My Mi 4C is running TS CM13.)
Results:
1. Original charger + original cable = 4.41V/1220mA
Not sure if the voltage measurement is correct. I thought it would be 9V as indicated in the post which I link to above. But at least the current is quite consistent with what the others have got. It takes around 2 hours for an full charge.
2. Computer USB 2.0 port + original cable = 4.24V/250mA
It takes forever to charge. I have no idea why the current is so low. The same USB port is able to output 450mA on another phone.
3. Original Charger + 3rd party cable = 4.21V/170mA
I have no other USB Type-C device so I can't test if the cable is functioning properly. But this is just weird.
4. Portable Charger (5V/1A output) + original cable = 4.36V/860mA
This feels normal.
So I have two questions:
1. Why is charging through computer USB port so slow? I have selected "Charging only", not running any ADB.
2. Can Mi 4C work well with 3rd party cables?
It would be great if you could share your charging experience with Mi 4C. Thanks in advance.

I think the thing with Ampere is, it needs to have your screen on to measure. And it doesn't really measure the current, it takes the average charge rate of your battery and converts that to Amperes based on your total battery capacity (that is why it takes a few seconds to show). So whatever you read in ampere is your net charge rate, not what the charger is providing (whatever is draining your battery is included in the equation, your screen will be the biggest drain, you can test this with the brightness).
So that is why your usb charging looks like it's at half rate, it is probably 450-500 when the screen is off.
The 4c works well with 3rd party cables, provided they are not faulty of course. After all, the original cable is also just a transformed usb 2.0
The phone will basically never pull more power than it can handle. The charger however could be damaged if it's coupled with a bad cable and a device that draws more power.

look at this!
https://forums.oneplus.net/threads/charging-analysis-between-oneplus-2-and-xiaomi-mi-4c.387573/
The AMPERE App shows you the current chargeing ampere minus the usage and no Votlage from the charger!
The app show you 4,41 V and 1220 mA that says the battery has a voltage 4,41 V that is the charge state (battery %) and the
1220 mA say that the charger charge with that speed minus the actual using (-~300mA) 1220+300=1520 mA voltage unknow

Can't really say that Ampere or any other app for that matter is accurate in measuring the charging current. I would say get an actual hardware (i know there's one that you connect to the charger) that measures charging current if you really want to test charging current that bad.
As for me I only charge my phone in 2 different ways:
1. Thru the stock wall charger. From 0-100, it takes roughly 2hrs and 20mins. Quite fast for a battery with 3080mAh. Slower when compared to other 2015 devices with quick charge 2.0 i.e. the LG G4 that charges 0-60 in 30mins vs the Mi 4c's 0-40 in 1hr. Hopefully this is just a kernel limitation which remains to be seen till Xiaomi releases the kernel source.
2. Thru my powerbank with 2A output which takes about 3hrs+ from 0 to 100

Try this app: https://play.google.com/store/apps/details?id=com.slash.electron&hl=en

I think the decision of making USB 2.0 with type-C connector is kinda faulty. I tried using my Mi Pad 2's cable which is a true type-C and the charging time is much faster. I don't want to use 4c's cable anymore.

So far the most effective combination for me has been aftermarket qc2.0 charger and factory cable. With that combo, charge times have been comparable to my moto x (2014)
Using any of my micro USB cables with a type c adapter has resulted in substantially slower charge times, regardless of charger.
I have a couple other third party type c cables coming tomorrow. Hopefully I can find another successful combination.

does it come with usb3 (+cable)?

As far as I know it's a standard USB cable with a type C end slapped on it.

sounds kinda useless

I wouldn't go so far as to say its useless. It charges the phone and allows for data transfer. Those are fairly useful things.

well, i was more relating to the nature of the cable as stated before:

anyway, i got the phone myself now and gonna try some other cables/chargers. my plan is to compare AUKEY, Blitzwolf, RAVPower and Qualcomm devices. big effort, but i have made pretty bad experiences with chargers (slow, noisy etc...)

Review: Choetech 10400mah QC 3.0 powerbank & 18w QC 3.0 wall charger-great combo!
I've been using these for about 2 weeks now so I wanted to share my experience.
They both arrived in nice minimal packaging. Cardboard boxes. The battery bank contained the powerbank, a nice thick USB micro cable and a USB a to USB type c cable. Both are thick and should last a long time. The powerbank is a nice metal black one, with chamfered edges.
The wall adapter comes solo as the wall adapter itself. I received the black one made of plastic.
Ports- the battery has both 2 charging ports, 1 the qc 3 port and 1 regular 1amp port. Then there's 2 recharging ports, 1 microusb and 1 lightning port. I've got an iPad so if you have a lightning cable it'll actually take both the Lightning port and the qc micro USB port to recharge, speeding up the recharging process.
The wall adapter has a single USB A port, which is actually reversible so it'll take the USB end both ways. A nice touch.
Ok testing this I used both a G5 and I used the wall adapter to recharge the battery, since the battery is qc compatible for charging and recharging. The wall adapter is just as good as the oem wall adapter in charging the G5. Both chargers took about an hour to charge from a dead phone. Impressed.
Then I used the powerbank to charge the G5 using the qc3 port and included type c cable. Again it was charging the same rate, finishing at about an hour. Compared to a qc2 charger I'd say there's about a 10-15% difference due to the faster charging up to about 60-70% before trickle charging.
So for the powerbank recharging it with a normal non-qc took around 6-6.5 hours. So using the qc wall adapter it charged noticeably faster, at just over 4 hours. Then on top of that if you use both the qc charger plus a lightning cable it cuts about an hour off that. Very good results for a 10400 capacity. Was able to get over 3 charges on the G5 with room to spare. The battery has 4 lights that are blue, with the first one turning green when utilizing qc for both charging and recharging.
It's a great combo. I used the bank to charge the G5 and the extra port to charge Bluetooth headphones when needed. I like both products. Any questions let me know. Thanks!

Quick Charging with Aftermarket Chargers?

I'm sure this phone works fine with aftermarket chargers like the Anker PowerPort Atom PD 2, but will it charge the phone faster? While the 18W fast charger included with the phone is good, it is admittedly slow to charge the massive battery this thing has.. I don't really care about reducing the lifetime of the battery all that much given that i usually don't use a single phone for longer than an year so i'd be happy if an aftermarket charger can charge the phone faster without setting it on fire.. Any thoughts?

I currently use USB-PD 30W charger + type Cs cable, and it shown fast charging. But I am not sure which standard it use because it also support QC4+, MTK PumpCharging, VOOC, Samsung's adaptive charging and Huawei super charge XD

Sketchy as it is used for marking 30W wireless and 100W wired I believe. Mind using an app that checks the reall wattage speed? Maybe (Ampere)?

Redmi Note 8 Pro uses Type-C interface, and the data transmission standard is USB2.0. Supports Quick charge4 + fast charge protocol, USB Power Delivery (USB PD) fast charge protocol, MediaTek Pump Express 2.0, 4.0.

Give me link for charger Turbo plisss

For me the pixel 2xls charger is showing turbo charging screen as posted above.. charging at 3300 to 3500 mah on accubattery..
For the Stock charger it never went above 3000mah

On stock have 2400 max that way need New charger

I use "Baseus adapter 30W" its quick charge if you use usb cable to tpye c, but this charger use turbo charge if use type c to type c cable

My Qualcomm Quick Charge 3.0 charger shows quick charge. It's one from Hama I got a couple months ago for about 20-30 quid. I am pretty sure any QQC 3.0 charger will work

So is it beneficial to go for aftermarket chargers, specially while using custom roms?
