OMG that is ridiculous. And i thought all the time that i got a "super charger" since i bought my Ipad 2.

Dont get me wrong, mine charges my ipad scarily fast. It does its job really well. Its just only amazing in its own eco system. Apple all over.

On the bright side, if the ipad charger is your primary phone charger, you can nearly halve your current charge time by getting the orange tipped BlackBerry playbook charger.

But the Blackberry charger would not be much faster than my EP850?

I was sometimes too lazy to use the original Sony Charger ans so I used the Ipad charger for all mobile Equipment.

well i have ep850 and ec600l. using battery monitor widget i got 1000-1200 mA when charging. but it's only when the data connection is off, with data connection's on, it's varied from around 100 mA and always got its peak at around 900 mA.

with 1000-1200 mA shown, full charge took around 1 hour 10 mins (from below 5%), but with the data connection's on, it took more than 2 hours just the same with my old LG's 0.7 A charger )

Dear all,
I’ve tested some different chargers and cables on my SXS and I could confirm, the charging time strongly depends on the both ones together:
The original EP800 with its own cable supports 900 mA / 4.9 V. This charger should have 850 mA.
The HTC charger model TC P300 with the original charge cable from SXS supports 1200 mA / 5,25 V. It goes pretty hot, because its nominal current should be 1000 mA by 5 V. The charging time with it from 20% to 100 % is less than 2 ours.
The both chargers, used with a cheap fake USB – micro USB cable supports only between 580 mA to 640 mA.
Generally, I’d like to confirm, it doesn’t matter what label stays on the charger. You should check the Tension output and use a copper wired charge cable. The charger could be 5 V / 100 A, but with an iron wired fake cable You’ll need a half day to fully charge Your SXS.

My XS is charged in less then 2 hours with Sony charger and Sony cable

Hi All,

After reading everything around the web re fast charging and seeing that Sony want €30 for their fast charger I decided to do some tests.

To test I cut a usb "fast charging" cable and removed the usb plug - this cable has a much thicker power cables (red and black) so should be able to take any current I throw at it.

Next I got out my digital bench power supply and set it to exactly 5.0v - this power supply has a digital amp meter built in that is very accurate - note this power supply can output up to 5 amps - easily enough for "fast" charging.

Next got my Xperia S and attached it to the bench power supply.

Test 1:

Phone on, usb pins 2/3 not connected to anything - Current: 280 to 500mah - appears to fluctuate depending on the processor usage.

Test 2:

Phone on, usb pins 2/3 shorted, Current - 700ma

Test 3:

Phone off, usb pins 2/3 open - Current: 500ma

Test 3:

phone off, usb pins 2/3 shorted - Current: 1.45 amps

Test 4:

Switched phone on while connected, pins 2/3 shorted - power used - 1.45 amps

Test 5:

unplugged and plugged back in the cable to the phone - power used - 700mah

Therefore, it sees to get fast charging to work you have to have the phone powered off initially (though you can power it on) and a usb power supply that supplies at least 1.5 amps - though probably needs 2 to be safe. The phone appears to be "intelligent" i.e. checks to see if pins 2/3 are shorted and whether the phone is on or off.

Now assuming the battery is 1700mah this means that 80% of it is 1360mah in a perfect world it would take 55 minutes to charge it 80% using a 1500ma current.

Will do more tests tomorrow (30 min test) and report results.

Doc.

Okay, done some more tests:

Appears to work via a curve:

charging starts off at 1.4 amps, this increases to 1.51 amps in the first 10-15 minutes.

After 30 mins - 45% charged average 1.5 amps
After 45 mins - 63% charge average for 15 mins 1.4 amps
After 60 mins - 80% charge average for 15 mins - 1.3 amps
After 75 mins - 91% charge average for 15 mins - 1.3 amps
After 90 mins - 97% charge for last 15 mins - 0.55 amps
At 90% it dropped back to 0.55 amps.

Doc.

I think the fast charging story is plain bull****:

My Neo (2011 model) charges from 15% to 80% in half an hour too with the stock charger.

err.. 1750 v 1500 mAh (provided u havent change the battery), dual core v single core, 720p v 480x854

if im google it right, ur charger is EP800 (850 mA) which already a good charger compare the usual 700 mA charger from other brands.

but imo, what matter most here is the current (charging amperage). i tried the EP850 (1500 mA) with other phone, they only show charging current ranging from 700-900 while if my sxs uses it, it shows 1200 mA.

and some people here testing with other (modified) chargers, and wmccann2 said the phone can take 1450 mA when charging. which is very impressive.

It is very simple:

Battery is 1750 mah approx

850mah charger - will take 2 hours to charge the batter

at 1.5amps it will take a little over an hour.

for safety the charging circuit uses a curve so it takes approx 90mins if it has "unlimited" power.

The power adapter will provide whatever power is required up to the design maximum of the supply. The phone draws what power it needs - if it tries to draw more than the power adapter can provide it will either burn it out or the adapter will get very very hot - think of it like a light bulb, a 100w bulb will draw approx 0.5amps, a 200w will draw just under 1 amp etc. your home circuit wil provide up to maximum 63amps before the fuse trips (assuming you connect directly to the main fuse and there is no breaker with a smaller ampage in between).

Basically it is the phone that decides the power it needs not the power adapter.
