Wall charger and charging time

---

After I read several infos about this topic ...

Is that true that the Nexus S has limit of the amount of power it takes from the wall charger?

Suppose, it has limit of 750 mA.

Even if we use 1000 mA or 2000 mA, the Nexus S will take 750 mA during charging.

So, having much bigger mA charging rate will NOT speed up the charging time.

Am I correct?

Yesterday, I checked my Nexus S during wall charging:
65% charged at 01:57
87% charged at 02:48

So, it is about 22% per 50 minutes.

100% = 227 minutes (3 hours 47 minutes) ... almost 4 hours.

No task was performed, except turning on screen to check batt %.

And I was using HTC Desire charger (5v 1000 mA).

How long is yours?

Using an iPhone (1000mA) nubby it takes sometimes over four hours to charge mine

It definitely seems limited to me - though it seems that 1-2A chargers do cut 10-20% off of the charging time of the .7A stock charger. I said 30% in another thread, but further testing indicates that's not the case. Maybe the limit is around 750 or 800mA, and the stock charger doesn't really give .7 ?

if you want to charge the battery real fast

don't charge inside the phone

use a Wall charger for the battery, and it charges 100% in a little over 2 hours

the ones you find on eBay or Deal Extreme

find the ones that charges at 1000 mAh

you wont find any wall chargers for 2000 mAh (only available for cars)

the highest i've seen for wall is 1200 mAh

in my case it came in a combo so i got 2 extra batteries + wall charger
