Supplied charger is a Quick Charge 2.0 charger?

[milesg]

I've only charged my Z5C a couple of times but I noticed that it seemed to charge very quickly, checked the product code of the very neat USB wall charger that came in the box ( "UCH20" ) and sure enough it looks to be Quick Charge 2.0 compatible charger.

A nice bonus I wasn't expecting so thank you Sony!

UCH20 output is 5 V/1500 mA, same as the EP880 so not sure how you can see significant charging speed. Only UCH10 is Quick Charge 2.0 certified with output of 5 V/1800 mA

That's interesting, because it definitely seemed faster to me than my old Z3C charger.

And when I checked the spec on this page http://www.sonymobile.com/global-en/products/accessories/usb-charger-uch20/specifications/ it lists "Quick Charger UCH20" at the top above "Product Specifications", but Qualcomm Cetification isn't mentioned.

Then here (http://www.xperiablog.net/2015/09/20/sony-uch20-usb-charger-bundled-with-the-xperia-z5-family/) they mention "When Sony first announced the Xperia Z5 series back at IFA 2015, it initially tagged this accessory as a ‘Quick Charger’"

Wonder if it failed the certification, but still has the circuitry so is effectively Quick Charge 1.5?

I have a 3rd-party Quick Charge 2.0 charger on the way so it will be interested to compare the charge time difference.

Ok, ran my phone down to 4% this evening and plugged it into in the UCH20.

With the phone on, this is how it charged:

Start = 4%
20 mins = 22%
35 mins = 36%
60 mins = 60%
80 mins = 80%
100 mins = 95%
110 mins = 98%
121 mins = 100%

Not as fast a "quick charge 2.0" charge I think, but faster than I ever remember my Z3C charging?

Will it try it from completely flat with phone off next time (which might be a few days away... )

Well not quite QC 2.0.
The lab test Qualcomm quotes charged a smartphone with 3300mAh battery for 30mins
QC1.0 > 0% to 30% (5V / 2A)
QC2.0 > 0% to 60% (9V / 1.67A)
And 0% to 12% on a conventional 5V / 1A charger.

The Z3C came with a 5V / 1.5A charger just like this Z5C apparently. And the Z5C has a slightly bigger (2700mAh vs 2600mAh) battery so I'll make a wild guess that it's about the same speed, if not a tad slower.

Shame it doesn't come with a QC 2.0 charger.. Would've been a nice touch to include it.

Yes, I know the Z3C came with a charger that is supposed to have the same output, but my Z3C didn't seem to charge as fast as my Z5C is...

My experience was similar to this, charging in about 2.5 hours

The only explanation I can think of is that I was using a data USB cable with it, and I'm now using a 3rd party one specifically designed for charging. I'll update with the actual Quick Charge 2.0 recharge speed when my new charger arrives.

why didnt they they give us the optimal charger with the phone in the box then? I was looking forward to faster charging times, but i havent noticed any difference

 

[Sid3wayz]

Well that explains that disappointment with my Z5C, I need a new charger.

Now if only there was an easy solution to the phones lag problems...

Interesting thing is, Sony doesn't use step charging for Z5C and Z5P.

Z3C's max was 1800, so it's faster than Z3C.
