Could you check/modify also those values:

qcom,ibatmax-ma = <1600>;
qcom,ibatterm-ma = <160>;
qcom,ibatsafe-ma = <1600>;
qcom,maxinput-usb-ma = <1500>;

To something like... erm 2200?

And ibatterm to sth like 320...?

EDIT:

After some research I think this parameter causes the Z3 to charge faster:

qcom,ibatmax-ma = <2150>;

vs Z2:

qcom,ibatmax-ma = <1600>;

or at least it limites the

qcom,ibatmax-ma-under-step
[Xperia Z2 Android Development] AndroPlus:
OK, uploaded v63c_QC2.0_1800 and v63c_QC2.0_2150;)

v63c_QC2.0_2150 have same ibatmax-ma-under-step with Z3.

[Xperia Z2 Android Development] Jackos:
I flashed v63c_QC2.0_2150 and I was able to go 1900mA in Ampere.

However my wattmeter still shows 10,4W.

However I think the device charges faster. Maybe we could tweak those values a bit higher...

Let's wait for [MENTION=3056043]Haldi4803[/MENTION], so he may test this more precisely.
[Xperia Z2 Android Development] TheFerhatKing:
Gonna test it too, because I'm gonna update to 5.1.1 (Existenz 3.0.0), using my Aukey charger.

[Xperia Z2 Android Development] Haldi4803:
[MENTION=5169444]AndroPlus[/MENTION] [MENTION=856195]Jackos[/MENTION]

Doesnt look good :(

Thats stock .580 with v63c kernel.

Seems like we really need some modifications in system.

Even over 60% no change. Dropped from 7.15W to 7.08W
[Xperia Z2 Android Development] Jackos:
I'm getting much higher values in Ampere. How's that possible?

Did you try the v63c_QC2.0_2150 with or without my flashable file?
[Xperia Z2 Android Development] TheFerhatKing:
Same bro.. Using v63c 2150.

Sony Xperia Z2
[Xperia Z2 Android Development] Haldi4803:
Without! this is a fresh .580 upgrade with old userdata and v63c 2150 flashed.

Thats why i mentioned kernel only will probably not solve this issue. Your script only increases the Battery Temp limits right?
[Xperia Z2 Android Development] Jackos:
It also increases the wattage limits found in sysmon and starts the hvdcp daemon.

charge_current_limit:0 usb_watt_limit:10000 dc_watt_limit:15000

That's what I use. The charge_current_limit:0 means it's unlimited.
[Xperia Z2 Android Development] Haldi4803:
10W USB is not enough.

Whats the difference between USB and DC?
[Xperia Z2 Android Development] Jackos:
USB means its charged from a PC for example. The charging device identifies itself.

Ampere shows it detected "Netz-Ladebetrieb" so you're charging using DC settings. I could make a test version for you using 15W for the USB detected input, but I don;t think this would make any difference. Also it could hurt the PC if you connect your phone to it.
[Xperia Z2 Android Development] TheFerhatKing:
Even with PC USB 3 port? Because it can get more power

Sony Xperia Z2
[Xperia Z2 Android Development] Haldi4803:
Well well well.

Edited sysmon.cfg to 15W and check this out! It works

[MENTION=5169444]AndroPlus[/MENTION]

Full success!

USB 3.0 allows 0.9A @5V therefore max 5W

USB 3.1 more with Type C
[Xperia Z2 Android Development] Jackos:
That's perfect :D

Let me release rev5 in a few minutes.

Thanks for proving me wrong, that's awesome :D
[Xperia Z2 Android Development] Jackos:
Please find attached my latest Quick Charge 2.0 enabler allowing the device to draw ~15W from the charger.

EDIT: For QuickCharge 2.0 to work you need both my flashable file and the AndroPlus v63c_QC2.0_2150 kernel. If you have a locked bootloader, just my flashable file will give you a bit faster charging.
[Xperia Z2 Android Development] Gmobilize:
So this only works together with androplus kernel?

Kinda dont want to unlock bootloader tho :S

[Xperia Z2 Android Development] TheFerhatKing:
Great guys I know we could get this damn thing working :D!! Thank you for your great work guys cool.. [MENTION=5169444]AndroPlus[/MENTION] is it possible to get 2500mA, if you modify it more? To get 50% in 30 min we need about 3000mA charging xD. For example mine charger can handle up to 18W.

Sony Xperia Z2
[Xperia Z2 Android Development] Jackos:
I don't think this is safe to modify it that high... Even at ~2300mA the device is getting quite hot.
[Xperia Z2 Android Development] Haldi4803:
Trial and Error xD i really don't understand why USB limit occurs when it's definitly connected to a DC charger... but well.... it seems to work.... gonna check on my USB3.0 port on my PC with hardware if it's drawing to much, just to be safe.

Uff... it FULLY works only with AndroPlus kernel v63c2150 because that one increases the limit, i think it should halfway work on stock too.

Activating the hvdcp daemon and charging on 9V with Stock Limits might work.

To you want to burn your phone or use your phone to cook eggs ? ^^
[Xperia Z2 Android Development] TheFerhatKing:
Maybe both^^ Okay I understood it, my battery gets hot to 50°C+ its enaugh. Thanks again to all that helped to get QC2.0.

Sony Xperia Z2
[Xperia Z2 Android Development] Haldi4803:
Over 60°C is not healthy.... i would try not to go over 55°C for longer periods.

BTW; USB Ports on the PC are safe :)

Draws:

12.5-13.5W from Aukey2.0 Quickcharger

5W from Sony EP880

4W from USB3.0

2.5W from USB2

Charging duration Benchmark incomming :)

Wish i already had the Bluetooth module for my YZX Studios Power Monitor^^
[Xperia Z2 Android Development] Jackos:
I set temp_warm to 60C (it will throttle charging, if you reach that temperature), wondering, if I should lower it to 55C...
[Xperia Z2 Android Development] Haldi4803:
Hard to say, i'm not really versed on that topic :( Japanese Z2 Limits would be good i think.

BatteryUniversity says charging between 0°C and 45°C

(Smartphones use Li-Ion, most likely Lithium Cobalt Oxide: LiCoO2)

But in the next page they're talking about high temperatures are okay for charging... bad for health.

But well... they're talking about a freakin 130°C ^^ so i guess we're still Safe with 60°C

Btw, i had a maximum of 48.2°C while charging (21°C Room temperature).

If i get that Right 1Coulumb in our case means charging the phone full (3200mAh) in 1h. We're currently at 90 Minutes which would be 0.75C so that still seems okay.

But yeah....

One thing that everyone who uses QuickCharge 2.0 should accept.

It does reduce battery health more than normal charging!

We don't know by how much, might be 10% less capacity after 500 cycles, or might be 20%. But it's definitly worse than normal Charging. So don't use a QuickCharge device when you intend to let your phone charge over night.

Except you don't want to use your device for more than 2 years, then it doesn't really matter ^^

Edit:

Battery also says 60°C Maximum

EDIT:

---------- Post added at 02:48 AM ---------- Previous post was at 01:50 AM ----------

Uhgs.... taking a closer look at the data we're definitly over the 1C xD

60% Charged in 45 Minutes... Not far from Qualcomm's claimed "60% in 30 Minutes"

Comparing to the old Test with 10W Limit this does get kinda lot hotter...

It's about 10°C Hotter than normal ^^ might not be healthy... might not be healthy at all.
[Xperia Z2 Android Development] Jackos:
My chart:

Some notes:

After 70% the charging current goes down to 1800-1700mA.

After 80% the charging current goes down to 1500-1400mA.

After 90% the charging current goes down to ~800mA.

It charges faster than the Z3C stock + UCH10. Nice.

It charges slower than Docomo Z2. Weird.

Fully charged (from 1%) after 120 minutes.

I happy with the results :)
[Xperia Z2 Android Development] showlyshah:

I know it was possible, sorry i cant be with you for all these, as my laptop broke down. And my test files and findings were in that. Now its back. So i can continue.

I will flash the new Qc kernel and Jackos script, and cross match with the files i retrived from docomo firmware.

[Xperia Z2 Android Development] Jackos:
It's impossible to get it fully working without Kernel modifications - thus unlocked bootloader is needed. You can just flash my rev5 - it will give you a bit faster charging, but don't expect getting close to Qualcomm Quick Charge 2.0 standard.

[Xperia Z2 Android Development] showlyshah:
Magnetic cable will never work with QC-2.0, SINCE the usb d+ and d- lines are a must to enable quick charging mode on the charger. To put simply, magnetic port have no communication channel with the charger and hence u will get low currents. But since there are some changes in the charging configuration scripts, u will get a better charging current than the stock with this mod enabled, even if u use magnetic cable. 30-40% better charging times.
[Xperia Z2 Android Development] showlyshah:
There is nothing this mode does with battery drain, as of reports till now. U must check for apps, or configurations that drains the battery.

[Xperia Z2 Android Development] gamer649:
Why is this? Once the phone battery hits 100% shouldn't it kill the charging current to the battery and power the phone through AC?

Just asking cause I'm curious :)
[Xperia Z2 Android Development] Haldi4803:
Well... why bother with Quickcharge if you have more than 5 hours time? Charging every night for 2 years with a quick charger instead of a normal one might reduce battery health.

Software security is good enough to stop charging from 99 to 100% and let it drop to 96 or 97% so keep it plugged in is no problem at all.
[Xperia Z2 Android Development] barmalini:
Very few car chargers can cope with hight Z2's energy demand while in route navigation mode, so no matter if you charge it or not, your device will run flat empty after some hours driving. Luckily, now QC2.0 chargers can do the trick, so I never arrive in the remote town with half-empty telephone.

They say 80% in 65 Minutes? Well... we need 66 Minutes ^^

But i don't really believe this one.... charging with 3 Ampere? ah common... no way.

On another note... my Bluetooth module arrived today :) any my battery is on 25%, so tomorrow i will make graphs with Charging current :)
[Xperia Z2 Android Development] barmalini:
Hard to tell. I've got like four or five of them, some branded some nonames, but not a single one is good enough. I'm tending to think that in my case it's a combination of factors like el-cheapo cables, crappy adapters, loose contact in the socket and indeed, maybe some overheating, and when all put together, they make charging the phone in a car nothing but pain.

And to bring all this misery to the end, I have ordered Aukey QC 2.0 car charger from Amazon and a couple of their cables. Expecting them to arrive tomorrow.

And again, let me thank you and all other guys who have worked on this project, you rock as a team and individually, thank you!

[Xperia Z2 Android Development] barmalini:
I'm sorry to read about your negative experience with Aukey cable, but I must confess quite an opposite.

I have just compared my charger with its native cable that came with it, with two generic cables and the results are as follows:

1. Generic cable #1, Chinese noname bought on Aliexpress for less than 1Euro. With this cable the charging current is 500mA as measured with Ampere app.

2. Generic cable #2, also noname, but bought in local electronic store for 1.50Euro - produced 1600mA.

3. Aukey cable, that was bundled with charger - 2250mA.

Also, Aukey cable is the thickest and the stiffest out of the three.
[Xperia Z2 Android Development] showlyshah:
Obviously.. Thats half true. Because

1) we never charge our device battery with 1C ( columb) . Ie. One columb means if u charge a battery of 1A with a current of 1A, the battery is said to be charging at 1C range, and 2A for 2A battery= 1C, SIMILARLY, IF WE HAVE TO CHARGE OUR Z2 BATTERY AT 1C, WE HAVE TO GIVE 3.2AMPS. Because our battery is 3200ma or 3.2A.

Also 1C is ok for a charging, anything over 1C for any battery will cause a temperature rise and eventually it will damage the battery. Here we are charging at a rate of about 2200 ma, which is about 68% of the 1C capacity. So no worries.And after all li-ions are designed to charge and discharge at higher rates, so even 1C rate is normal for li-ions. They are said to be charged at. 0.5 to 1C. And the best rates for prolonged life is. 0.5 - 0.88 C. All we have to keep notice is the battery temperature, that shdould not be crossed, 75 degrees.

2) As heat is the main enemy of li-ions. Thats why li-ions are said to be kept cool. If any of u had laptops, u heard that, dont plug it while u use it hard, its not mainly because the battery tends to rapid charge-discharge rates, (li-ions are designed for that high capacity and rapid charge discharge rates), its because, when u use laptop, the temperature of the working laptop will be pauses to battery, and these charging - discharging rates will also build up heat, the battery will have to suffer more than 75 degrees and will ruin the battery life.

Now in a phones case, we dont experience that much heat, and the sony battery is designed for 60Degrees, now we had a solution for that too, we implimented cut off at 60degrees, which means the device will stop charging at 60degrees. Btw, we never saw such high temps in normal charging ( or using while charging), and well everything on ur device will shutdown at that temp. So dont worry for that 60 degrees.

You can belive me, i used to study these, as i am an electronics and electrical engineer by profession. And still u dont belive, u can check google. Atlest they dont lie for some reasons.

Thanks all.

[Xperia Z2 Android Development] jerpelea:
hi all,

When you think about enabling qc2.0 on a device you should consider that qc-2.0 is a reference design which means that it can be supported by OEM if all conditions are met.

To enable qc2.0 on a device an OEM has to consider

Hardware

- Battery parameters (battery has more parameters than capacity)

- Power dissipation and power envelope (Sony devices are plastic, glass and metal)

- Charging circuit

- Charger

Possible problems

- damaged battery in a waterproof phone (sealed and without replaceable battery)

- damaged motherboard due to power circuit stress

I think that OEM engineers have disabled it with a reason, and in the box is a regular charger instead of qc2.0
