Z3+ fast charge issue, with sony uch10 take only 600mA at 9V ,~5.4W and 1.3 A at 5V 6.5W

[mit_z3plus]

i have just receved my new Z3+ indian version. 

after updating upto Android 6.0 . lastest version .

as i can see after few charege tests all from ~2% battery , first with simple sony CP-AD2 5V 2.1A charger it take around 1.3A ,~6.5W, the battery is ~ 11WAh, so it will take around 2 hours or more to full charge, no problem. 

but when i charge with  sony quick charger uch10 , 

it take only ~600mA , at 9V with is ~5.4W ,this even less than normal charger.  so it is going to take even more time than normal charging. it takes around 2.5 hours to full charge.

, quick charge claim battery to be 60% in 30minute  but it is only 20% because of low current. 

so i wanted to ask is there any issue with my phone or charger? 

or you "sony" limits the charging rate in Android 6.0 because of minor heating issues with eairly version of android? 

if you are limiting then at least limit to a little higher so that it will be qual to nomal charing at 5V. 

it is really "stupid " have quick charge and charge even show than normal charging. 

i hope to get some help

Sony has been showing interest in battery department of Xperia z series after they introduced qnovo adaptive technology for Xperia x series. Slow charging is to ensure battery stabile and to increase degradation of battery cells.
