I bought Xperia D6503 4 days ago, the phone was ex display and the condition is still very good like new. Functions work fine. My phone Android OS is still Lollipop 5.0.2 bulid number 23.1.A.0.726. No new OTA update available. I found that the charging process of the battery takes a long time enough to be fully charged (100%), it could be more than 3.5 hours. But, today I find a solution, maybe not the best, but at least, in my opinion, it is better than before.
My phone brightness is around 50%, I turn off the Throw Settings feature. I usually charge my phone when the battery is under 30%, i noticed today I begin to charge from 15:18 (from 27%) to fully charged at 18:24, with the condition much time I let it keep charging with the Sony charger in the box to wall charger, and my phone is active, receive notification adn sometimes I read notification and reply messages. The charging process takes around 3 hours 6 minutes, better than before I did my phone charged that could take up to 3,5 hours or more. But, if I play a games while my phone is being charged, the process charging is become very slow and the percentage of battery maybe will not go up.
This Xperia Z2 is remind me to my Vivo V5, it also takes up to 3 hours for fully charged. Well, the phone (global version) that come to Indonesia region doesn't support fast charging.
That's my experience.
