For getting good charging speed I use ambrane 13000mah powerbank (1A out port) n it charges my c4 dual really fast... sometimes Almost like quickcharge feature! ;-)

Sony Xperia c4. And allsony Mobile battery is very bad. Samsung batteries are very very good.
The phone gives very good backup while doing anything except gaming ( drains battery faster), i dont understand how people say that it battery backup is very poor, i think some dont know how to get the most out of their battery
Amr, 02 Mar 2016I had my c4 3 days ago.. It is good in general . But the bad things are: Th battery take mor... more4 hours is not normal,it only takes 3 hours to charge, due to itsbig display u can face problem while handeling it with one hand, wont face the problem if u have a big hand. And if u are using ur phone while charging, dont use it will take more time to charge with screen on,i advise u to use EP880 charger by sony

It is good in general . But the bad things are:
Th battery take mor than 4 hours to recharg... is that normal??
And the phone is not easy to use it by one hand.
It does everything you need and the battery lasts enough for a day's work. Of course, if you get using mobile for videos, games and music will not last all day.
Awsome mobile, with magnificent camera lens, great pictures quality and display, go for it without another thought.
MY C4 is the best!
To avoid heat at the back, u need to close other apps which is idle but still running in your system.
Another why it is hang? I advised u to have an external sd card so everything u will be downloaded will not consumed your mobile's storage.
Proven and tested in my case with other cp brands when I put or place a protective gear like tampered glass or leather case on my cp it can affect the cp performance because the ventilation at the side and its back cannot pass through. And take note to consider its size, the thinner your cp is, the more it is sensitive and required a good hands of a father (technical term used in law)
all people who received defective models of xperia c4 will come to comment here hahahahaha
