Quick Charger 2.0 not working on Z2

Hi guys,
I have an D6543 (Brazilian Model), there is no difference between D6503.
I checked the Qualcomm website a lot of times, and Z2 is in compatibility list: https://www.qualcomm.com/products/snapdragon/devices/all?feature=Quick Charge 2.0
So, I purchase the Tenergy Quick Charger 2.0 at Amazon, and for my surprise, it's not working at all. Only normal charging.
I tested at 1%, and in 30 minutes only 11% was charged, VERY, VERY slow.
The light indication at charger is saying that is on normal charging.
I'm really frustrated.

Fastcharging is disabled on xperias for safety
Charging should be between 1-5 hours even without fastcharge

My z2 only take around 2 hours to fully charge from 1%. Just using the stock plug charger.

I dont think fastcharge is at all posible with the Z2
It charges at 1500mAh using the factory provided charger and trying to go beyond that isnt safe at all.

i dont know about it, but ive charged my z2 several times from 1% to 100% only take 2 hours - 2 hours and 30 minute. And yes, i've heard people charged thier z2 atleast 4hours to completly fully charged from 1%. My phone is still standard, under warranty(havent mod anything yet and still unrooted).

I don't know why. Z2 has the Snapdragon 801, which is compatible with Quick Charger 2.0, as Z1 was compatible with QC 1.0.
LG G3 also has the 801, but LG does not enable the QC, that's why it is not at Qualcomm's website. It's weird, because Z2 was recently added to the list, and the main product page says it's compatible.
In the end, I just lost money because their poor support and information.

As said its pointless trying to increase the charging rate
I learned when pushing it past 1500mAh it starts to damage the device usb port and
battery

Not exactly poor support, if its safe to use and certified safe to use sony would have put it in the features list on their website but it wasnt there when i bought the phone nor when i last checked.
As said check my reply
The device charges at as fast as it safely can with the factory provided charger

I'm using envi rom.
I have a normal 2,2A usb charger.
When I use the usb port to charge i have really slow (6h from 0 to full charge) to reasonable charge time (3h from 0 to 100) depending on the used cable.
But when I use the magnetic aftermarket cable than I get insane charge time, only the last 10% from 90 to 100 is not fast but it certainly uses 2A as it is from 0 to 90% in about 90 minutes.
The phone gets slightly warm but far from the temperature it gets with intensive usage and the magnetic connection gets warm too, but nothing alarming imo.
The full metal and glass design makes heat diffuse very fast.

That sucks I'm coming from a one plus one and the charger was very fast.

Xperia Z2 and Z3 supports Quick Charge 2.0.
You need charger which supports Quick Charge 2.0, though.
http://weekly.ascii.jp/elem/000/000/223/223383/
This site is in Japanese, but it says you'll get 13W when you charge with charger which supports Quick Charge 2.0 and with normal charger you'll get 10W.
Normal charging is already fast enough, so you won't notice big difference.

Either they know nothing about electronics or they cannot calculate ^^
1. it should show 9W..... 1.8A x 5V so their meassurement device is not exact (hell, these Wallplug meassurement things are made for 220V ! so you measure 0.045A you can't expect them to be realistic, they're for up to 2000W not so low values.)
2. 9V x 1.8A = 16.2W but this is wrong again as the Quick CHarge 2.0 speccs are up to 4.5A for 9V
So if it really is charching with 9V it only uses 1.44A
Oh... and btw the Stock Sony Wall charger EP880 only has 5V 1.5A
Let's hope some people who know what they're doing are gonna test the Z2 or other phones with Quick Charge 2.0

I'm unsure about the battery but this is why QC 2.0 utilizes a higher charge voltage. Also why in computers, all high current devices now run on the 12v rail instead of 3.3v or 5v, because high amperage at low voltage would damage cables and connectors. If we had expensive graphics cards pulling 400w at 3.3v there would be a huge problem with heat and necessary wire size. There is more resistance in metals with high current / low voltage vs. high voltage / low current and this is what can damage the USB port.
This is also why at 120v AC we have issues running high current draw appliances vs 220-240v circuits.
Also why high voltage is more fatal, because it travels more easily through our skin, and etc.

I contacted Qualcomm by email, and they replied to me after a few days.
Xperia Z2 officialy does not support Quick Charger 2.0, only in JAPANESE models.
They updated their website, and removed the information, that's sad.
https://www.qualcomm.com/products/snapdragon/smartphones/sony-xperia-z2
FYI guys, Sony Brazil sells Z2 and Z3 with Smartband, so, our OEM charger has only 0.8A :crying::crying::crying:

Just purchase some charger with 5V 2A output and you will be fine..
I have tried using the standard charger 5V 1.5A if i am correct and it took around 3 hours..
And i tried using OnePlus charger 5V 2A and it is noticeably faster

I've already compared it with a normal 1.5A and it;s charging faster and the device also gets warmer.
I have a lot of apps running in the background, so my results may be other than yours.

Hello,
quick question: is it safe to charge our Z2's by S5 charger - 5,3V and 2,1A?

i dont get this. If the stock charger is 1500mA and the batery is 3200mA it should take only 2h10 to fully charge(more or less). But mine takes like 3h (brand new phone, charger and cable, all stock)

yes its 1500ma with a 3200ma battery but concider the cpu. your phone is awake for 25% of the screen being off so it should take a over 2hrs10m to charge unless you have xposed amplify installed.

Nexus 6P Not charging rapidly

Is anyone else not seeing charging rapidly with their stock charger?

No, I saw rates of 1500ma with a 2.4 amp car charger, usb a to c cable (screen showed rapidly charging). I also saw rates of 2400ma with the stock charger usb c to c cable (screen showed rapidly charging). I am guessing my battery was not drained enough to see higher charge rates.

I think your phone needs to be like 50% charge or less to really see the benefits of quick charge.

It was at 15% when I tried it. I have the stock charger and the Google 2 port 22.5w charger. I was plugged into the 2 port charger, but tried the stock charger for a minute. I may have had to leave it on the stock charger longer. Otherwise non "rapid" charging still took less than 2 hours from 15% to 100%.

I tried to edit my title I know it's not quick charge, but you can see youtube reviews where their phone shows "Charing Rapidly" on the lock screen and not just "charging". The phone can take up to 15W from the Type C port.

I tried the stock charger when the phone was at 60% and it varied between 1 and 2 amps. I'm going to run another test when the battery is lower. Sucks though because I typically try not to drain it that much.

Ok, I started charging with the stock 6p charger at 26%. I'm now at 74%. This charger does not ramp up in a linear fashion like other lithium-ion chargers that I'm familiar with. It's constantly ramping up and down over and over. The highest it's achieved was 2.8 amps for a few seconds and I would guess it may be averaging maybe 1 to 1.5 amps.
I'm wondering if it's even working to spec. Seems to me it ought to slowly ramp up to 3 amps, hold it, and then slowly ramp down at about 90%.
Anyone else monitored their charge rate?
Update: It took about 90 mins to go from 26% to 93%.

That sounds faulty. I can do that with a A->C setup in an hour. The google charger should be somewhat faster (40 minutes? Based on 2A vs 3A).

Load ampere from the play store and watch the charge rate. I wonder if it's just mine that has this very strange charge curve.

Glad I'm not going crazy. Coming from a Galaxy S6, I wasn't expecting the fast charge on this to be that slow.
From 46% to full on the stock fast charger supplied with the phone, it took an 1 hour 3 mins.
From 46% to full on my Anker IQ 71AN7105 which is supposed to output at 5V, 2.3 Amps, it took 1 hour 20 mins.
Both said the phone was "charging rapidly" when I plugged it in.
Just measured on the Anker, and it's showing charging rate at 640-790ma. So you're doing a lot better than I am! No wonder it's taking an age to charge!!!!
That's like normal non-fast charge surely.

I don't trust ampere to be honest.. charging current is supposed to vary but not the amount it's showing. I wonder if it's showing charging minus load, so having the screen on will make it give incorrect results, as will the various CPU sleep states, wifi, 3G, etc.
The real world test of time from x% to 100% or how many % in 30 minutes is somewhat better in that it's measuring the end result. I'll try to do that. (/me switches rob ross on twitch to drain some battery).

A typical charging curve is shown below. The shapes of the curves might vary some by battery and circuit, but in general a battery will draw full current (up to some limit) for a period of time and then the current draw will steadily decline. This is normal. A battery will charge from 0%-30% much faster than from 70%-100%. Beyond allowing 3A to the battery, there appears to be no "fast charging" technique employed by the 6P.
The real key is what is the charger actually outputting? This should be tested by an instrument, not the phone. If, for example, the charger is outputting 2.9A and the phone is 10% charged and only drawing your 700mA there is probably an issue OR the power control is limiting current for some valid reason. Maybe the battery temperature.

I was expecting a curve like this but it was a roller coaster starting at 26%. I expect the charger is putting out because I measured a momentary blip of 2.8 amps.
As was mentioned, Ampere may be part of the problem but I don't have other tools other than a simple time to full calculation. Do we even have specs as to what's that supposed to be?

OK here are the results I got:
Both started at 10%, with identical settings (although on different days, can't help that). Normal working settings.. I avoided having the display on except for checks and it was sat still so allowed to doze.
Code:
30 Mins 60 Mins 75 Mins Total Time
USB A 47% 81% 92% 93 mins
USB C 50% 85% 95% 82 mins
And expressed as % per minute
Code:
30 Mins 60 Mins 75 Mins To full
USB A 1.23 1.13 0.73 0.40
USB C 1.35 1.16 0.66 0.71
So, C (well, google's charger and cable) is around 15% faster for me* than A.
Around 90% charging visibly slows to a crawl on both methods. The first 80% or so are fast, but interestingly C gains most at the end as it doesn't slow down as much.
Edit: If you ignore the timings at the bottom, it looks very similar to the example graph posted. Which is expected I guess.
* YMMV, standard disclaimers, etc.

one thing to note is that the phone will also charge slower if your screen is on and generating additional heat. The phone will throttle the charging rate based on the temperature of the battery.

So while it's 15% faster, the battery capacity is more than 25% larger. So how is the real gain achieved?

I'm thinking that the google charger isn't sending 3A anyway.. You'd expect more difference even if my normal charger is going as high as 2.4A (and I'm not sure it goes that high without QC). USB C might be capable of it but this phone/charger combination isn't.

Does Quick Charge or Fast Charging support on this device?

Hey guys, I wanna buy this phone but I have question about charging, does it support quick charge or just fast charging only? Thanks

I Saw Geekyranjits very detailed Faq video.. He said it Supports only 5v/2a charger speed.. he tested it with fast charger but it charged Normally as stock charger speed ... here's the link to his video...

The phone only supports fast charging for now. The bundled charger is a 2A and 10 Watts one. It takes about 2 hour 40 minutes to charge.
But the chipset does support Qualcomm quickcharge 4.0. Yet we don't know if the board supports it. If it also supports it, maybe ASUS will enable it via an OTA update. But its very rare in such cases and if they don't release an OTA, probably you would find a supported kernel and custom ROM here.
If the board doesn't support QC 4.0, then don't worry. You won't get it anywhere. Probably, that's why there is no QC supported charger provided by ASUS.

Mine takes almost 7hours to charge. When I check using ampere it shows only 900mA max of input rate. But I think there is no any problem with my charger because it's normal when I use it to my other phone. Anyone has the same issue? I've been using any method that everyone suggest in some forum but it ended up in no change at all.

No need to turn off mobile , simply switch off data and wifi.

What's with this charging issue for everyone.
Also like take 5 hours to charge full battery.
2 hours only chargers from 10-45%

Charging problem
My Zenfone Max pro m1 needed 4 hours to charge from 70% to 100%....!

Mine only takes about 2 hours to go from 10% to around 80-90%. the charger first says "Charging slowly" then within 2-3 mins it will say "Charging" and then within 3-4 mins it will say "Charging Rapidly" and then it only takes about 2 hours to charge 80-90% with the bundled charger. I don't know if a better charger would increase the outcome but lets see.

I have a MI Quick charger,
and i use it always from the day One of using this phone,
Previously it used to take the same time as the bundled charger,
but after the last / August 2nd update, i can see some sort of quick charging working,
Because i never saw charging rapidly on the lock screen before this update,
and as per my observation, 5% - 80% takes approx 2 hrs (Quick charge way), and slows down there after,
i haven't tested with the original bundled charger after this update though,
Will share the screenshots after testing.

Fast Charging working
Yes the phone supports fast charging can see from the screenshot

The bundled charger supplied with the phone is rated 5V/2A/10W which supports QC 1.0
Asus ZMP M1 runs on SD636 which theoretically supports QC 4.0. But it is not implemented at kernel level (probably due to licensing costs payable to QC which will raise the cost of the phone)
So effectively, fast charging is not supported on stock kernel. (And I may entirely be wrong !)

Here are the screenshots,
This one with 2 hours and 34 minutes (5% - 100%) is with the Mi quick charger 3.0 charger.

And this one with the 3 hour (17% - 99%) is with the bundled charger.

Anything above 1A can be called fast charging. So 5V/2A can be called fast charging. Although it is assumed that if device supports 9V and 12V then this indicates QC level fast charging.
A more accurate comparison and result can be obtained from Ampere app. You can use any charger but the phone will draw only that much power which is supported by the board. Also,many things affect the charging time e.g. length of the charging cable, heat dissipation by the charger etc.

Please suggest me a charger bcz my stock charger is damaged.

Would you please suggest me a good fast Charger for Asus Zenfone Max Pro M1 because my stock charger is damaged and the service centre is refused to replace it because of a small crack on the charger case.
Or
Can i buy the Mi Quick charge 3.0 instead of a fast charger.? Can i charge my phone with the quick charger 3.0 safely? Is the Mi 5V 2A charger is same as the Asus stock charger? Because asus stock charger not available to buy from online. It is only available in service centre and also need to wait a while.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Google Pixel 3 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

The Pixel and Pixel 2 used to charge "fine" through a PC port. The pixel 3 charges extremely slowly. For example my Pixel 2 would be at 50% battery and using the USB port on my car it would be close to 90% when I got home. Under the same situation, the Pixel 3 would only be at 55%. Same problem using the PC port. I know I know it's NOT supposed to be fast charge but I am only stating the facts and differences. Stock charger charges fine.

Pixel 3 charges very slowly on my existing 2.4A (per port) multi usb charger. Clearly it's not a PD charger, but it always provided enough juice for my nexus 5x to charge quickly. Clearly the pixel 3 doesn't like it.

Can confirm this also. Ampere indicates that it pulls less than 200mA on any non-USB type C charger. This is different from my previous Pixel 2.

With Samsung fast wireless charger, s9 goes from 20%to 100 in less than 2 h, pixel 3 charged only 25% in 2 h....... Charging speed is awfull if you don't use Google chargers

Something is not right there. I see around 1000 mA with an old 1.0A charger and around 1300 mA with various 2.4A ones. Even with 'slow' wireless I see 500-600 mA
Sent from my Pixel 3 using XDA Labs

With Nov security update. No improvements. It charges fine with pd charger but insanely slow with any other.

My Pixel 3 charges plenty fast for me. Although, I typically use my Dell Latitude 20v (45W) PD charger.

I'm not an expert at this stuff and certainly might be missing something but charging at 1000mA from a 1A charger should be physically impossible. Wouldn't that be 100% efficiency?

Yup.. Charging is too slow.. Infact, the charging time estimated (which is shown on the lock screen when the phone is being charged) is also wrong.. May be it gets adjusted over time...

The estimate is adjusted over time. To my knowledge, all fast charge technologies are able to charge much quicker when the battery is low, but then slow the charge down as the battery approaches a fully charged state/heats up. The estimate would simply be a guess, since they likely are, app status, ambient temperature and battery condition dependent.
This can be seen in the graph on xda's quick charging comparison. Note that all the technologies start out quite fast but eventually taper off. Also note that USB-PD is the slowest (most conservative) of the technologies after the battery gets to about %40 charge.

I would add that my new pixel 3 does appear to charge a little slower than some of my previous devices, however I've got several devices that use USB-PD so the versatility of USB-PD and ability to use one charger across my devices more than makes up for the extra 30 minutes or so of cellphone charge time. Guess everyone's expectations are different.

"Fast charging" on the Pixel is via Power Delivery. This is only possible over USB-C; PD can negotiate higher charging rates by increasing the voltage. This is not possible with PC type A ports; type A is rated for 5v, 3a max.
Qualcomm Quick Charge does adjust voltage and uses type A ports, but it uses the data pins for rate negotiation, while PD uses pins unique to USB-C.

No. The charger is able to deliver 1000mA, but the total power delivered to the device will be less than it draws from the mains supply (the difference wasted as heat).

The Pixel and Pixel 2 used to charge "fine" through a PC port. The pixel 3 charges extremely slowly. For example my Pixel 2 would be at 50% battery and using the USB port on my car it would be close to 90% when I got home. Under the same situation, the Pixel 3 would only be at 55%. Same problem using the PC port. I know I know it's NOT supposed to be fast charge but I am only stating the facts and differences. Stock charger charges fine.

Exactly. Google has really messed up the charging speed. Pixel2 used to be fine with usb ports. Pixel3 charges faster only with stock charger with which it came.

Yeah, that's what I thought but the comment I replied to said it was charging at 1A from a 1A charger. I would expect maybe 800mA from a 1A charger.

Yeah idk if I just mixed up my numbers (I had been testing multiple charges) or what. Tried again and it averaged more around 600

The phone doesn't like to charge fast if the battery tempeturature is "high" (higher than 35 ºC). It's just a very agressive charge trhottle. Try charging again but in a colder weather or room.
It was my experience.

The charger that comes with the phone is not fast charger?
Got my phone yesterday and when I charged it, it said it's slow charging....
Edit
Second charge was fast charge according to info on screen.

After Dec update, the PC port charging is normal, not rad, not slow but normal. Problem fixed.

I felt similar way until today. But today at around 20% battery I put my Pixel 3 at Pixel Stand and have got that:

I already posted regarding strange behavior of wireless charging: https://forum.xda-developers.com/showpost.php?p=78315849&postcount=73:
Before I've got original Pixel Stand, I used generic wireless charger. No surprises, it chargers P3 slowly. But there is more. Sometimes it doesn't charge P3 at all. Way more strange, that almost the same behavior I have with Pixel Stand. After some days I began to suspect there is a regularity - the charge at full speed works with at least 85% of charge at phone. If the charge is lower, the possibility the charge would be at rapid speed is pretty low. It can claim it charges rapidly, but in fact it doesn't charge at all, since the charge is going down at the same rate as phone out of any charging. I definitely have relatively small statistics and can not say for sure that 85% is a "red line" for triggering wireless charge start (regardless of speed in my case). Today even at 91% phone battery wireless charging at Pixel Stand didn't start at all (with "charging rapidly" announcement at screen and slowly discharging phone). Other functions of Stand work pretty good regardless of what's going on with charging. I didn't contact Google Customer Service since the results are unstable.

In case of regular charging through the USB-C cable from native Pixel charger I've never had any problems. But wireless charging even with original Pixel Stand doesn't look good. At the generic charger even after Dec update charging goes south - not charging at all or with original Google wireless charger just like at screenshot - rapid charging in day and a half. It's better, than no charge, but for $79.99 for original Pixel Stand it has to be faster.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Realme 3 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Very good
One of the very few things that are good out of the box about this phone. Charges from 10 to 100% in 75 minutes even with screen usage while doing so.

Same here. If I want to go out and the battery is around 40%, I just plug the charger for a while. By the time I'm ready to go 15-20 minutes later, it's already around 70%. Thats more than enough juice for 9to5 office hours.

Realme 3 pro uses it's own VOOC 3.0 fast charger right? And it use snapdragon 710 that support Qualcomm quick charge 4.0
But Can realme 3 pro use qc 4.0 or even 3.0 atleast, like qc 3.0 powerbank or car charger maybe? They don't really have vooc accessories don't they? Just usual vooc charger?
Edit: I've found 6000mah vooc powerbank made by oppo itself, but the price is like 3 or 5 times more expensive than usual 10.000mah qc 3.0 powerbank price in here, insane ? i don't wanna pay that much for powerbank, so please still looking forward to see the compatibility between realme 3 pro and quick charge 4.0 or 3.0
Thanks

Charging time for me :
30 min - 0 to 44%
1 hr 25 min - 0 to 100%

I lost the original cable. I can't find a authentic vooc 3 cable anywhere. Please help. Without that particular 7 pin cable, it's 5 v 1 amp instead of 5 v 5 amp.

For me, it's 36 hours. I use it all day, then it stays at standby at night while I'm asleep. Then I use it another day before charging. Works perfectly.

I also looking for the same thing. It's quiet difficult to find one. I also looking forward the compatibility. Peace
Edit: i've try to search any info/video about the compatibility, and it's looks like realme 3 pro does not compatible with quick charge 3.0 (it will only be a normal charging if using qc 3.0). Still looking for qc 4.0 compatibility, but still not found one. About vooc powerbank, i came across with 2 other powerbank (both 10.000mah btw), not made by oppo, that support vooc charge for realme 3 pro. Unfortunately, it appears that it only available in my country. I've try to search it in banggood or amazon, but it didn't available. In theory, if the chip support qc 4.0 it should be compatible. But then again, what do i know. Peace

VOOC is a Proprietary technology of Oppo, Other brands won't have it even if they advertise as one. Beware.
