Charging time with the charge that was in the box (5V 850mA) is very slow and takes almost 4 hours which is very annoying. So if i use a charger with 5V 2A will the device charge faster? It is supported?

I am never sure why there is so much uncertainty about these things:

CURRENT - MAX defined by the charger ACTUAL defined by device
VOLTAGE - MAX & ACTUAL defined by the charger

With some devices, the most common being Snapdragon phones, they can request the charger supply a higher voltage for quicker charging, but BOTH THE PHONE AND CHARGER NEED TO BE COMPATIBLE.

In this case the charger changes its voltage.

In any case, with a 5V charger, your phone will pull what it can.

There is no spec given, however from my experience of different chargers, I would say about 1A is the max for our phones.

Remember that if your phone is ON it is probably pulling 100-200mA so it has a material effect on charging speed.

As others have said, branded chargers are best.

Not because they are faster, but they provide a much cleaner 5V signal. Cheap chargers can damage your device as their voltage variation can be huge, even on a small 800mA load.

Hi how can I make my battery charge faster? It usually takes 2 hours from the charger & 4 hours from a pc usb port. The battery drains fast when using wifi or mobile data. Is it safe to use an iPad charger?

You probably cannot use a iPad charge, as it is not USB so will not fit, even with an adapter, and the voltage will be different.

HOWEVER FOR FASTER CHARGING WE HAVE HOPE:

Our MediaTek X10 chip supports their equivilant of FastCharging by Qualcomm:

Hi I have tried charging with an iPad 12W USB Power Adapter & it works!, charge time is only around 1 Hour! so far I have no issues with the phone at all.

Sorry I see what you mean, a charger but with a standard USB port which happens to be supplied by apple.

Yes, that charger is 5V (well 5.2V) so yes it would work fine.

Looks like it does charge a lot faster with 5v 2A charger. Even my old xpera P had 1.5A charger. Why sony included only 850mA charger with this phone? Using old xperia P charger, charges the phone a lot faster
