Question [Q] Charging Current

Hi All,

Was wondering if anyone knows the maximum current the SGS2 can draw for charging purposes. I had a look at the wall charger provided with it, and it's 0.7a; it takes forever (my opinion) to charge compared to my last phone. Just wondering if it is worth my while investing in a more powerful charger.

Cheers

If you take the battery out and look and the sticker then it says there 1000mA

Excellent thanks; Can't get the back off my phone (fingernails).

Also, at the start of the SGS2 charging cycle, my wall-plug power meter reads 5.1 W.

5.1 is what the adapter is pulling. All of that isn't getting to the phone. Funny thing for my is the phone charges faster off my blackberry 0.75a charger then it does off my Galaxy I 1a charger.

Someone in another thread mentioned seeing something in the source code about the phone drawing at most 650 mA (instead of a more typical 1000 mA) during charging. If that's the case, a more powerful charger by itself won't help; you'd also need a custom ROM that doesn't limit the charge current.

Does anyone know why Samsung would limit the charge current?

Speculation is that its a heat related problem. Don't want to pull a Sony and have the batteries explode on people... (but again, that's speculation)

I also heard that a smaller charging current extends the Li-ion battery's lifetime, even though I'd prefer quicker charging as the battery can be replaced with ease.

I second that. I tried it today with a 1A car charger (USB cig. plug) can't say it made a difference on speed of charge compared to wall one.
