Dear All,

What about the charging performance in your ZUK Z2's

They are claiming 83% charge in 30 min

But when I tested today with their stock charger its only 30% charge in 30 minutes (ie I charged from 21% ,It reached 51% and took 30 minutes exactly)

Can somebody share the battery charging performance??

Thanks and best Regards,

Liju

Hi Marcin,

I got this info from GSMARENA.They all mark QC.3.0 phones like that.

BTW, my charging performance update is 80 minutes From 21% to 91% ie 70%

If this normal ,I am ok or else if it will be improved by some qualcomm charger thats what I need to know from you friends..

Regards,
Liju..

Well, the stock charger isn't QC 3.0 enabled; so you'll need a third party one to test.
Dear Dude,

Yes I also feel so.

Charging update :-

21% to 100 % in 1 hour 55 minutes.

Qualcomm documentation claiming more than this on QC.3.0 and QC 2.0 even.

So we can conclude the stock charger is not QC.3.0 enabled,right??

for sure default charger isnt qc 20.0 and 3.0 also.

Qc 2.0 will force to 9v, and the stock charger is 5,3v.

i can check charging on qc 2.0 charger when i get to home.

I use a qc enabled Blitzwolf charger and getting charge times closer to the ones posted on gsm arena. Note, that if the charge is higher, charging slows down a little. So from 5% to 50% is much faster then 50% to 95%

well i just uploaded a link to a charget that i have. I have with qc 2.0. I dont have charger with qc 3.0.


I have tested now in qc 2.0 port and....it shows me 1.85a at 5.06v(it was flying), but definately the default charger(from the box) can do it better.

I have QC3.0 car version and charging is going very slow... Looks strange for me. I bother if it's a problem of a phone, rom or faulty charger?

Original charger doesn't have quick charging, right? Mine took 3 hours from 30 to 100% last night. Maybe I because of crap rom or cable/charger?
