Already tried those... Qc-2.0 is working in its half glory now.. That means z2 now supports qc current at 1700ma, but we have to boost it upto 2300ma.

Super slow
Why does my phone only charge at 850mah if I'm using a 5v 2a Samsung charger? When I tried the stock charger the speed goes down to 600mah... Why am I only getting half of what others are getting? I'm really thinking of switching phones as this is unacceptable. 5 hours to chatge the phone...

---

there´s no option to have QC 2.0 on locked bootloader?
i´m having issues to unlockl it with flashtool (bootloader unlock allowed: YES) is not the first time i´ve unlocked it, but now flashtool can´t unlock it, i think is windows 10 and have problems with adb drivers compatibility

Ya. Driver support may be the problem. Btw, if u have root, u can do it in terminal, just use the command.

Sony's Official EP880 charger provides 1.5A
You also have to include the Power the Phone is already using some power, so if you use "Ampere" app to check charging current, then you have to add about 250-400mA depeding on Screen Brightness and CPU load.

That still only adds up to about 1 Amp... And I'm using a 2A Samsung charger... Both that and the Sony charger charge at around 600-800ma

Hi all, I'm sorry to ask this, I'm using CM12.1 now, is there any hope to using the qc? Does it have any flashable zip to flash? Thank you ?

---

No big benefit if you don't have a kernel which allows for a higher current than 1.5A
