I lost my xperia z' s charger and so I brought a samsung note 2 original charger, since it is a 2000mA charger it can charge xz faster than its original cahrger ( xz can support 2 - 2.1 A charging current at max), and then due to loss of my usb cable along with the charger, I bought a 1.5 mts china cable. Ofcourse it do the charging, but its charging time is slower than what I get using a 1 mt high gauge nokia cable.
So this is what I learned, to get proper charging, we need to use original charger and a good quality high gauge usb cable too.
But since I wanted a lengthy cable of about 1.5-2 mts, I am going to buy a high gauge lengthy cable. Now here is my question;
Do anybody knows an app which realy works on xperia z which can detect the charging current properly?? I tried current widget, samsung charging current apps, and few others, all those apps shows some random numbers which changes randomly ( eg :- 300,206,540,750) , some does shows -ve values also, which totaly make no sense since I am plugged into a 2A charger!!
Thanks in advance.

Try Android Tuner app by 3c(available on playstore)
In app>>battery manager>>status shows the battery flow also the current capacity and a lot of other info
Also a negative value does makes sense...once your battery is fully charged the current flow is "cut-off" to prevent overcharging the battery and eventually damaging it.
If you feel that I've helped you in anyway, please hit the thank button

I already have that, think its not correct, coz I used a 2amp charger, ( note the charging current) this is why I asked. I think the stock kernel is not reporting it correctly???

I've been using my HTC Rapid Charger Quick Charge 2.0 with my new Sony Xperia Z2 Tablet and it charges in just under 3 hours for a 0 to 100% charge.
Not sure what the standard charge time is with the stock charger, since I haven't even taken it out of the box Just easier for me to use the same charge and cable to charge both my phone and tablet. Has anyone else measured that?
My HTC One M8 usually gets quite hot during quick charging, but didn't notice the same thing with the Z2. It only went up to around 35 degrees at the highest, for a short while.
I need 4.5 hours with stock charger (15% to 100%).

So 2.0 quick charging is working?
Do you really get 60% in first 30 minutes with HTC charger?
Yes, it's listed here:
https://www.qualcomm.com/products/snapdragon/devices/all?feature=Quick Charge 2.0
Does anybody know where to buy a quickcharge 2.0 charger with a euro plug?

No, those 60% in 30 mins is claimed with a much smaller phone battery..not with our 6000 mAh tablet battery. On my HTC One M8, it gets to about 50% in 30 mins.

Are you from Denmark? I bought mine from here: http://www.mytrendyphone.dk/shop/htc-tc-p1000-164522p.html
Not the cheapest option, but the only one with euro plug that i could find.
got official answer:
Thank you for contacting Sony Xperia Support.
To be able to utilise the Qualcomm Quick Charge 2.0 technology, the smartphone or tablet as well as the charger need to support Quick Charge 2.0. If you want to use a magnetic charging dock, this must also support Quick Charge 2.0.
Currently, there are no original Sony chargers that support the Qualcomm Quick Charge 2.0 technology. This means that, at present, you cannot charge Xperia™ devices using original Sony chargers utilising Qualcomm Quick Charge 2.0.
However, some Xperia™ devices and magnetic charging docks are prepared for and support the Qualcomm Quick Charge 2.0 technology. Again, as there is currently no original Sony charger that supports Quick charge 2.0, these devices cannot utilise Quick Charge 2.0 using an original Sony charger.
Regarding the charge time, according to our environmental declaration a full charge takes 5.8 hours while the tablet is turned off.

Wow, a normal full charge takes 5.8 hours? Even with tablet off..that sounds a bit crazy. Then im definitely glad i'm using the Quickcharger and getting it done in half that time..even with the tablet powered on.
As for the magnetic charger, it has been confirmed in other Xperia forums that Sony's dock and magnet supports Quickcharging, but most 3rd party ones don't. I'm using some cheap magnetic connector from eBay, and it charges quite slow (and half the times the magnet doesn't even keep it connected and it keeps falling off )
from my experience tablet charges in 4 hours (even if it`s turned on, from original SOny charger 1.5A 5V), from 20-30% to full. So this estimation is correct.
Anyone can recommend a good ansd cheap charger that support QC 2.0 or there already some thread about this on XDA somewhere?

Not sure where you are from but there are several good and cheap ones on Amazon:

http://www.amazon.com/Qualcomm-Cert...obile_desktop?ie=UTF8&*Version*=1&*entries*=0
There is not really any difference between all of them, as long as they are certified by Qualcomm to work with QC 2.0.
There's a list of all certified chargers on this page: https://www.qualcomm.com/products/snapdragon/quick-charge
and here is an especial cheap offer http://www.androidauthority.com/quick-charge-explained-563838/
So... do ALL z2 Tablets support QuickCharge 2.0 ? Because only the Japanese Z2 Phone supports Quickcharge!

Alright, can anyone confirm this for me? Wait, lemme start at the beginning...
So I was reading this Android Police article, hoping to get some quoting material for those times when a member thinks USB Fast Charge is the same as Qualcomm Quick Charge 2.0...
http://www.androidpolice.com/2015/06/12/quick-rapid-turbo-and-fast-charging-explained-what-you-need-to-know-about-charging-your-smartphone/
Y'know, all those times people ask a kernel dev "Why isn't Fast Charge speeding up my charging?" so I could swoop in and crush their dreams with "Fast charge means only more current draw when USB charging via PC. You're thinking Qualcomm Quick Charge 2.0, which needs hardware support, so ain't gonna happen."
But turns out, the Mi3/Mi4 DOES have the supported hardware (for Quick Charge 2.0 mind you, not v1.0 like in the Nexus 5)
https://www.qualcomm.com/documents/quick-charge-device-list
(Official document from Qualcomm listing the Xiaomi devices amongst the handful of QC 2.0 devices)
So can someone tell me if this needs kernel support? Or can I just buy a Quick Charger off Amazon and enjoy the benefits?
Or if this is at all LEGIT?

In fact I own an Mi4 which comes with a 2A charger that is normally supporting quick charge 2.0.
With MIUI it's charging 1.8A (of course 1.8A is around 2A minus phone consumption)
On all custom rom it's just charging max 1.3A with about same consumption, or even less.
So Mi4 support quick charge 2.0 with MIUI but not with any custom rom or kernel.
Anything regarding Mi3 ??

In the attachment 1 that is the stock charger of mi3 , in the attachment 2 that is the current of quick charge without the build.prop line. And in the last attachment that is that current with the buil.prop line.
In conclusion, without the build.prop line the lcd becomes super sensitive but higher current, with the build.prop line the lcd is fine but lower current than before

I don't think a 2A charger is an actual Quick Charger. (Obv it charges quicker compared to 1A ones )
Apparently for Quick Charge 2.0 technology, your Wattage/Power input should be around 18W (wattage is found by multiplying the voltage written on charger, usually 5V with current you're getting in ampere). Quick Charge 1.0 supported upto 10W which we're gettng with the 2A chargers, but I think we need an actual Qualcomm certified Quick Charger (which allow currents of upto 3A apparently) to see QC 2.0 at work.

Yes, this guy is right. 2A charger with 5V output is not a quick charger this guy talking about (Qualcomm Quick Charger 2.0). 12V charger output is.
Mi4 charger comes with 3 voltages 5V-2A, 9V-1.2A, 12V-1A...but maximum we get is 12*1=12W
Charging on xc kernel (cm ROM)
MI3 is not support any quickcharge. Even you use 2.0A charger, will give you same about 1.2A
What i know is i had Mi3 in past now i have Mi4 and mi4 comes with a Qualcomm Quick charger 12V-1A. It charges way too fast than Mi3 charger.
I use Mi3 Charger 5V-2A on Mi4 it took 2-3 Hours to get fully charged whereas Mi4 Charger takes 1-2 Hours to get fully charged.
It heats up a lot Charger + Mi4 Both
MI3W support QC 2.0, but needed QC 2.0 charger, for example Xiaomi Quick Charger 2.0 aka MDY-3-EB I`m found it here
Hey Peeps
Anyone else getting slow charging on SM-T810?
Using the bundled charger, I am getting average of only 680mA .... Definitely nothing over 950mA and that is even when screen is off...
Using the same charger and cable on my sony xperia Z3 easily achieve 1400mA ...
Same sort of numbers with other chargers etc... So pretty sure it is device not charger...

I just tested and am getting around 1500 mA. That is with my nexus 6 charger.
Bundled charger gives me around 1460 mA.
Are you certain it`s not the app that is wrong as the S2 is new and the app might not have been updated yet, Try the Samsung charging app below, you have to keep pressing the refresh button on the free version.

The charging rate can be anything from 300mAh to the maximum the power adapter can output, the tablet will determine the amount of power it will accept, and will jump from fast to slow charge depending on how much more power is needed until it reach 100%.
Thanks guys - obviously does not seen to be wide issue.
I tried the Samsung app above ... Sort of showed similar values ....
I did a charge from 69% to full and it took about 1.5 hours... So would be maybe 5 hours to charge fully?? Unless the device does much quicker charging at very low battery??
I will do a full discharge down to say 5% and then charge from there and see how I go.
Thanks again

I would install battery monitor widget from 3c on the play store.
A pretty comprehensive battery app and will give you a full history and time line of charging and discharging cycles.

Normally it will trickle charge slow once it reach approximate 80%, and is normally fast if the unit is almost power empty.
It's annoying. I've tried both ipad chargers and a 2.4A charger, but it will go to slow charging mode with anything else than the bundled charger.

Yeah i have found exactly the same!! Must be some sort of Samsung handshake protocol...
There is another thread on this that I have mentions about this, just use a good quality charger, or just go for a Qualcomm QC 2.0 charger from any known brand like htc, aukey, xpower, lots to name, just searh Qualcomm site for a full list.
It won't used the QC2.0, but all should work just like the OEM Samsung one
the ipad charger should be pretty high quality though, so I don't get why it's being so picky.

If you also followed the tab S thread, it's also been mentioned, Samsung tabs S are also picky, and yes all apple stuff don't work.
Should I rephrase it and say some good quality charger will work, even branded ones like sony may not even work, but my intital testing, most QC 2.0 charger will work.
The issue is that I'm trying to find one charger that will charge both my tab s2 and my iphone 6+ quickly. Any idea how qc chargers fare with iphones? The bundled tab s2 charger only gave my iphone 0.4A (it charges the tablet at 1.5A)
I have both sony and asus chargers with included cables work perfectly with iphones and sony xperia z3 and nexus 7... Hopeless with S2.... But s2 charger works fine with them..

Odd, my old Nexus 7 2012 charger fast-charges my S2 710 without any issue at all. I had it spare as the N7 died on me (the S2 is its replacement) and was initially wondering myself as I had a few supposedly 2A chargers at home which only slow-charged the S2 (or indeed under Android 5.0.2 said it wasn't charging at all, even though it evidently was, but 5.1.1 has fixed that).
That said this is a charger without fixed cable (but with a decent USB cable) and I know from Raspberry Pi experience that the cable is almost as important as the charger for getting decent charging (ie enough current) to the device on the far end.
I would make sure the USB cable is a decent one intended for charging.
Proper charging USB cables have the shield connected at both ends for use as ground which is why they are notably thicker.

I agree, a good quality cable is required, as well as the charger itself, I'm using a magnetic cable and a reversible micro USB cable with a OEM Samsung, Aukey and Xpower charger, I don't get the speed of the QC 2.0, but it isn't suppose to as the S2 is not QC 2.0 compatible, but it does charge pretty quick, it also charges my ipod 4, and my nw-ZX2 work without any problems.
I get the "slow charging" message when using the Galaxy Tab S2 bundled charger.
If I use the charger from my Note 4 (Exynos) I get faster charging and no "slow" warning.
Did Samsung bundle it with the slow charger??
I can confirm that samsung did in fact bundle the tab s2 WITHOUT a quick charge usb charger.
I also thought the tab s2 didnt come with quick charge. I have extremely slow charge times but my battery lasts for DAYS... I can fully charge it, put it in airplane mode and check on it after 2 days and be at 98-99% battery.
I also use the quick charge cable AND the quick charge usb adapter that came with my note 5 and the tab still slow charges..
Here the same problem use Samsung charger and cable charge from 20% to 100% in 6 hrs and when use HUAWEI cable with Samsung charger It charged in 2 hrs
I guess Samsung have poor quality cable *-*

Is Realme X2 Pro compatible with qc 2.0/3.0?
I´m using an Aukey charger qc2.0, and when it reaches 75% aprox, it stops charging.
qc 2.0 uses 12V, 9V, 5V
I´ve made some troubleshooting, using a safety usb tester (V, A, W, etc.) and I discovered that when changing from 9V to 5V charging mode, it freezes!! and stops charging. I started at 30% battery level, charging at 9V 1.9A (17W), and reaching 75%... Intensity dropped down to nearly 0A... was no charging... I unplugged it, wait 1 min, plug it again, and it started charging again, but at 5V 1.33A (7W)...
with other mobile phones and same charger (Aukey) it changes from 9V to 5V without stoping, so I am worry if it is a problem of my Realme unit...
Can anyone confirm this?¿?¿?

There must be a compatibility problem,
Maybe, if you unpluge and plug it again it will charge up to 100% (it works for me)
Let´s see if it can be solved in next software update, I will try to contact Realme support to let them know.
My charger at work also supports QC 3.0 (not oficially, LeEco Model EQ-248CN).
