Interesting. Still, in general, I can understand Sony being pretty conservative here.
[Xperia Z3 General] Rizera:
I am astonished to look at the results here...

Charing my Z3 Dual (D6633) with the stock OEM charger (EP880, allegedly 1.5a), I get on average 750mah according to Battery Monitor Widget, while leaving it charging and not using the phone while it is charging, of course. This leaves me to a total of 24.5%/h.

Why could that be? Will a QC2.0 charger help me get it any faster?

Also, if that is a Kernel limiting problem, there should be a way to third party it to make QC 2.0 available, shouldn't it?

Regards.

I use the charger from my note 4 with the magnector and my phone charges generally to 100 from 20 in about an hour and a half.
[Xperia Z3 General] tameracingdriver:
Bit in bold: Lucky you.... I am getting an average of just over 500 mah using the Sony charger and cable that came included. That is circa 6 hours to charge from empty to full. This is whether I use the Sony charger or the BB 2A charger I have, which charges my GFs HTC One M8 and my old N5 in around 1.5 - 2 hours. Making use of the magnetic (again, official Sony) dock makes no difference using either charger.

I'm trying to see how much it will charged completely off, but this is a really annoying part of ownership - not a deal breaker, but certainly very irritating. Perhaps my phone is faulty?

Edit: I've just tried 30 minutes with the phone turned off, using magnetic charger and stock charger and its gone from 50% to 67%, which is a fair bit faster - it was taking around 4 minutes to increase by 1% before, that is now up to 2.2% every 4 minutes, so is over twice as fast. So something in the software is restricting it.
[Xperia Z3 General] Entropy512:
No, it's a hardware limitation. The power going into the battery is the LEFTOVER power when the system power consumption is subtracted from the input power provided by the power supply.

So the higher the system consumption is with a normal charger, the less power that is left to go into the battery.

When charging with the phone "off" - it isn't really off. It actually boots into a limited minimal version of Linux that has one role: Charge the battery while using as little system power as possible - as many peripherals as possible are turned off and the CPU is usually kept locked at minimum frequency. Android calls this LPM aka Low Power Mode. Since system power usage is minimized, power to the battery is maximized.

Quick Charge 2.0 increases the input power budget significantly, which means that you can have much higher system power consumption without reducing the power remaining to charge the battery. Note that QC2.0 REQUIRES the D+ and D- pins of the USB port to be wired - so it will NOT work with the magnetic charging port (QC2 chargers will behave just like normal chargers if you use the magnetic port.)
[Xperia Z3 General] eosdigic:
I have a thick cable which can reach 1.4~1.5A with famous Chichony 5V 2A charger. Last week I bought Samsung Note4's QC 2.0 charger, which claims to have 9V 2A capability. But when use it with Z3, it only can reach 9V ~1A. So QC 2.0 is only 30% faster with my setup. It might due to Z3's hardware limit.
[Xperia Z3 General] PuffDaddy_d:
I agree - from everything I have read, it appears that our Z3/Z3C does not have the full QC 2.0 capability. It's performance more closely matches QC 1.0 from two years ago and may very well be why Sony does not advertise these as QC 2.0 capable. The long battery life renders this deficiency moot for me though.
[Xperia Z3 General] undercover:
Constant pull of 1.5A on a dock though, as long as charger is powerful enough. Charges at a very reasonable rate.
[Xperia Z3 General] Entropy512:
Try turning your screen on and doing something.

The battery charge current is limited to 4.35v@1.5A = around 6.5W

If you have the screen turned off and CPU idle, you won't see much more than 6.5W of consumption due to charging.

QC2.0 starts to matter when system power consumption (screen + CPU + radio + etc.) exceeds 4W.

6.5W for charging + 4W system = 10.5W power, which is nearly the 11 watt budget from a 5v@2.1A charger. (Cable losses mean you won't even manage to pull this off.

9V@2A gives you an 18W power budget instead of 11W. Although here, you may run into charge rate limiting due to thermal issues. The Z3's nonreplaceable battery means they need to be more conservative about battery stress during charging.

Most obvious difference is when running Google Maps Navigation.
[Xperia Z3 General] eosdigic:
I run StressTest v2.7 and could see 9V 1.5A on an external usb power meter. But it doesn't help battery charging time because the additional power is used by system, not pumped into battery. But at least I know my Samsung Note4's charger is not a fake one. (correction: it is a 9v 1.67A charger, not 2A)
[Xperia Z3 General] Entropy512:
It'll help battery charging time in cases where a 11W charger doesn't supply enough power to run the system and keep the battery charging at full rate (1.5A) - Keeping the system running is always the top priority over charging the battery, so if system power budget goes above 4W or so, you will NOT see the device able to reach its charge rate peak any more.

Honestly the best use case for QC2.0 chargers is car chargers, not wall chargers. It's much more likely the device is going to be used for extended periods of the time with the screen on and active when running Google Maps Navigation in a car.

Navigation is a notorious power hog. With a standard car charger, I've actually found it draining my battery even when connected to the charger. With a QC2.0 charger, the device charges at a decent rate even when running Navigation.
[Xperia Z3 General] jewelkobayashi:
I have recently bought z3 because prices have really come down.

I bought the docomo, a Japanese variant and flashed international rom on it.

I got tired of lugging around my z3tc.

Anyway, one of the reasons I went for Japanese docomo was that it supported QC2.0.

Not knowing fully if it was a hardware difference or software between the Japanese and international variant, I got it even at the expense of killing off nfc, because it was quite a bit cheaper than international variant.

Anyway, interesting interesting thing is, my z3tc fully supports QC2.0.

Using the same app, gsam, I see a clear difference in charging current.

I guess it is software determined, and was wondering if there is a tweak we could do to fully support the 2.0 standard.

From 5%, my z3tc charges faster to full by about an hours difference...

This is despite the bigger battery in z3tc, even though both have sealed batteries...I doubt hardware conservation is a valid argument to not adopting the full 2.0 standard

Admittedly I don't have the latest firmware in z3 since it is a pain onye rooted to casually update but it is still lollipop...
[Xperia Z3 General] Entropy512:
So you're saying that the Japanese z3 has the same charging current as other devices? I've always been surprised that it would be different than other devices in configuration.

And there's more to this than just sealed batteries. The z3tc has more thermal dissipation surface area in compared to the device's power usage (CPU/PMIC/etc. are all the same as z3, so same power usage from these but with a much larger device to dissipate the heat). So it does make sense that it can safely charge at 0.66C (3A into 4.5AH battery) for the entire duration of charging instead of 0.5C (1.5A into 3AH battery). What surprises me is that they allow 0.7C charging of the z3c below 60% battery - perhaps this device has some sort of additional heatsinking material.

- Z3 -D6603 stock customized CE1

- Aukey PA-U28 QC2.0 18W (5V-2A, 9V-2A, 12V-1.5A)

- Anker 28/21 AWG cable 3ft

Result (Ampere app):

5V 1630mAh

So no QC2.0

[Xperia Z3 General] infinitylook:
How did you test It? Did you use some software? If you use an app it won't show you real values. Quick charge only happens when screen is off
[Xperia Z3 General] PuffDaddy_d:
Unfortunately for us all, that's simply not true. It's been proven many times on this forum that the Z3 line of xperia devices simply do not support quick charge 2.0. Even Sony doesn't advertise these devices as being QC 2.0 capable. Sorry...

[Xperia Z3 General] Entropy512:
He used some app called "Ampere" - which appears to be misreporting vbus.

Also, it is most definitely FALSE that it only happens when the screen is off. For various reasons, the battery current limit is 1.5A. You can hit this limit (although unreliably) when the screen is off with a normal charger. You can NOT hit this limit reliably when the screen is on, and you absolutely cannot hit this limit when running Google Maps Navigation with a normal charger. QC2.0 makes the most difference when your screen is ON and the device is operating, not when the screen is off.

No, they support QC2.0. I've confirmed this using multiple methods with TWO different QC2.0 chargers.

Method 1: Plug Z3 into a Tenergy charger. Note that the charger lights GREEN, which it only does when in a QC2.0 mode.

Method 2: Compare the charge rate when using Google Maps Navigation and a normal charger. The device will either charge extremely slowly, or with many cables, it will actually DISCHARGE. With a QC2.0 charger, it will still charge at a reasonable rate. Especially if you've got a thinner cable like this one - http://www.amazon.com/StarTech-com-Micro-USB-Cable-UUSBHAUB3RA/dp/B001AR4NC8/ - One of the big benefits of QC2.0 is that high voltage (9v/12v) charging allows you to use lower-quality/longer/thinner-gauge cables. (Same principle as why our long-distance power grid lines run hundreds of kilovolts). You'll see far less advantage with the extremely thick Anker 28/21 cables.
[Xperia Z3 General] PuffDaddy_d:
I partially agree - QC 2.0 chargers will work with our phone, but as you mentioned, the phone is capped at 1.5A, which is not the full QC 2.0 threshold. It's more like QC 1.0. Whatever Sony did to our devices, it will not utilize QC 2.0 to its full, advertised potential. I can reach 1.5A with a tablet charger that isn't QC 2.0 or 1.0 rated at all. It will not charge as quickly as phones that truly utilize QC 2.0. If it did, then Sony would have advertised this as a feature. You will never see it mentioned anywhere on the product's website or manual. :(

Sony z3 charging issue. HELP!

Hi,

I bought my sony Xperia Z3 6 days ago. It charged great the first time. But after the second charge, I removed when it showed 100% but after a little use it started showing 50%. Still gave a great battery time and when the battery was low, it again went to showing 1 or 2 %. But that problem also went away after another charge. But now, the same problem occurred again. I charged it to 100%, used it perfectly but when the charging was somewhere around 45%, it again started showing 50%. Even though the battery lasted for quite some time after that but now the phone wont charge would neither turn on.

Help me out please! I updated my phone to lollipop 5.0.1 after the first charge.

Really frustrated.

Time for a warranty replacement.
[Xperia Z3 General] zeeshan11:
Frustrated!

Please NO!! I went to the retailer and he asked me to keep the phone plugged in to the supply. The problem according to him is that the battery went very low and the battery needs to be charged now until it gains some charge. He asked me to leave it plugged in for a whole day even. Lets see what that does. What do you suggest?

Phone was going really well. Awesome to be honest. Only if this issue didn't rise.
[Xperia Z3 General] PuffDaddy_d:
The retailer does not know what he's talking about. Leaving it on the charger longer will not do anything because the phone cuts the supply power once 100% is reached. Swap it while you still can.

The problem with my phone is that its just not charging no matter what. He asked me to keep it plugged in in order to get it to start charging. What is the key combination for Z3 for a simulated battery pull? It involves power button and volume buttons. just dont know for sure. Anybody, please?
[Xperia Z3 General] Entropy512:
VolUp + Power for 3-4 seconds will force a shutdown, but it is the exact same as fully powering your phone off from the menus.

Seriously, time for a warranty replacement. If the phone is reporting 100% and then rapidly dropping to <50% immediately after unplug, the battery is totally shot - probably has a short internally and if you just keep it on a charger for extended periods it might go POP.

update

Further tests with usb meter:

Aukey PA-U28 QC2.0 18W (5V-2A, 9V-2A, 12V-1.5A)

- "original" (ebay) Sony magnetic charging cable: 5.32V 1.57A

- Anker 28/21 AWG cable 3ft: 8.99V 0.91A

- original Sony cable: 8.98V 0.93A

original Sony charger EP880

- "original" (ebay) Sony magnetic charging cable: 4.85V 0.79A

- Anker 28/21 AWG cable 3ft: 4.86V 1.09A

- original Sony cable: 4.86V 0.89A

So it is compatible with qc but not the full 2.0 :(

I measured 8~9W no matter what I tried it with. I think it is limited by software side.
[Xperia Z3 General] Entropy512:
I've stated in a few places, the limit of current into the battery is approximately 6-6.5W (1.5A@4.35v is the highest wattage you'll ever see going into the battery itself) - add background power consumption of an idle device and inefficiencies, and you get 8-9W.

If you turn the screen on and use the phone, you'll likely see a much larger difference between the QC2.0 wattage and "standard" charger wattage.

I use Samsung Grand I-9082. I don't know much about android's workings and followed a youtube video to root my phone. I was then on 4.2.2 and then out of curiosity upgraded to Cyanogenmod 10.1. It was fine so when Cyanogenmod 11 came out i flashed it too using the same CWM recovery. Since about a month ago my phone is becoming unresponsive sometimes especially at lock screen and occasionally it reboots by itself while i'm in the middle of something.

Is there any way i can go back to android 4.2 from CM 11? I should also mention here that i don't want to unroot, just downgrade to a stable rom that my phone will be able to adequately function with, without causing any trouble.

I am using Geniatech ATV Android Set Top Boxes running android 4.2.2 for a current project. I might put some of those devices in public places like shopping centers. These boxes are connected to the local network there by cable or wireless.

I have a VPN connection to ssh remotely into the boxes (using debian kit) and on the boxes USB debugging is enabled, so that i have ADB access, which I use for chrome browser observation as well as for updating or installing new applications.

The problem is that everyone on the same local network as the box can also use adb to connect to the boxes and then have full access to everything, which is a big security problem.

What I want to do is restrict the interface of adb to only work over the vpn connection.

Alternatively I need a way to stop and start the adb daemon using my ssh connection to the box. The problem here is that I only connect to a debian kit instance running on the same box, which uses the same filesystem but doesn't have access to the start or stop adb commands.

Does anyone have an idea how to achieve this? I can't find a lot of information on this special requirements.
